I already tried to do that with Android's GridView but got strange things. The grid distorts when scrolling up and down and at some point, when scrolling up, it dissapears. If I put all rows with the same height, it works, but as soon as they are a bit different, the problem appears.
So it seems I have to make a custom view. It has to have very good performance and low memory usage. Would be enough to extend, for example, Relative Layout, and put all my items with certain top and left margin? Or do extend View and draw directly to the canvas? Or a Scroller?
Embedded question: Will this, (maybe it depends if I extends some Layout or directly View), manage to load only the things which appear on the screen (the list is very long and I don't want all the objects in memory at once) or do I have to implement this myself?
Thanks in advance!

I am writing a Python script that compares 2 XML files. In both files we have data for which the id's are equal to those in the other file.
E.g.
Source file:
<id>123456</id>
<data>blabla</data>
......some other data......
<id>abcde</id>
<data>gfkgjk</data>
......some more data..........
Target file:
<id>123456</id>
<data> </data>
......some other data......
<id>ghijk</id>
<data>gfkgjk</data>
......some more data..........
As you can see in the above examples, not all ID's that are in the source file are also in the target file. Furthermore, although 2 data groups have the same ID, one has the "data" tags filled out, the other hasn't.
My programme is supposed to have a look at the source file, extract the id and the text between the data tags. Then it looks into the target file, and if there is data with the same ID and empty data tags (like in the example above), it fills in these empty tags with the information from the source file. (By the way: apart from the ID and the data information, the two XMLs are completely different, therefore I can't just keep the source file).
Right, I was able to extract the ID and the info between the data tags.
Now I'm trying to write a function to compare the ids and replace the empty data info if there is one.
However, I'm not very familiar with Python and functions and need some help.
Here is what my function looks like:
def replace_empty_data():
for x in xmlData_id_source:
if xmlData_id_source==xmlData_id_target:
target = re.sub(xmlData_2,xmlData,target)
return target
file_target.close()
There's probably loads missing in the function, but I don't know what. It doesn't give me any errors and is simply not working. Variables except x have been defined in earlier parts of the code, so this is not an issue.
xmlData_id_source is the ID from the source file
xmlData_id_target is the ID from the target file
xmlData_2 is the data information from the target file
xmlData is the data information from the source file
I am grateful for any kind of input.
Thanks in advance and kind regards

id | column 1 | column 2 | ... | column n
The data are downloaded from a server whenever users press a button. However, the data table doesn't have a fix number of column (as well as row) every time user downloads it from the server. For example, the server may send data with 3 columns the first time. Then it might send data with 5 columns the second time, etc...
Given this scenario, I think the database is probably the right data structure to use. My plan is to create a database, then add and delete tables as necessary. So I have been reading various tutorials on Android database (one example is this one http://www.codeproject.com/Articles/119293/Using-SQLite-Database-with-Android#). It seems to me I cannot create new table with variable number of columns using the sqlite database. Is this correct? In the onCreate(SQLiteDatabase db) method, the "create table" command must be specified with known number of columns and their data types. I could provide several "create table" commands, each with different number of columns but that seems like very crude. Is there a way to create database tables with variable number of columns on the fly?
Another alternative probably using several hash tables, each storing one column of the data table. I'm seriously considering this approach if the database approach is not possible.

I'm writing an app that allows the user to send text from an `EditText` to a `TextView`. If the user makes a mistake, the user can hit the space key to bring the most recent text sent from the `EditText` to the `TextView`. This works sometimes, but other times, it gives me an `IndexOutOfBounds` exception.
textInput is an EditText, back1,2,3 are the three most recent strings (with back1 the most recent)
public void onTextChanged(CharSequence s, int start, int before, int count) {
if(count==1&&before==0&&s.toString().equals(" ")){
textInput.setText(back1);
}else if(s.toString().equals(back1 + " ")){
textInput.setText(back2);
}else if(s.toString().equals(back2 + " ")){
textInput.setText(back3); //causes error if back2 > back3
}
textInput.setSelection(textInput.getText().toString().length());
The above code checks if the user hit the space key, and if so, what to do with it. If the user pressed space on an empty EditText, they get the last thing they sent. If they hit space again, they get the next to last thing they sent, and so on. This is still a bit rough, but I hope you get the idea.
The OutOfBounds exception comes from taking a large item in the `EditText`, hitting space, and setting the `EditText` to a smaller string. I assumed it was because the cursor is at the end of the `EditText` and could no longer be there when the text got smaller, so I tried adding `textInput.setSelection(0)` right before the `setText()`. That didn't help. I also tried setting the `EditText` to `setText("")`. That didn't work either. If I comment out the lines of `setText(back#)`, everything works fine.
An example:
A user types in "hello", "hi" and "hey" in that order.
back3 = hello, back2 = hi, and back1 = hey.
Hitting space once will set the EditText to "hey"
A second tap will crash, since the `setSpan(3...4) ends beyond length 2`, presumably because back 1 is larger than back2.

I experience horrible performance going through the BufferingForwardingAppender instead of directly through the RollingFileAppender and I really don't get the reason.
Here is my configuration
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="c:\" />
<appendToFile value="false" />
<rollingStyle value="Composite" />
<datePattern value="'.'MMdd-HH'.log'" />
<maxSizeRollBackups value="168" />
<staticLogFileName value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>

<bufferSize value="512" />
<appender-ref ref="RollingLogFileAppender" />
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="BufferingForwardingAppender" />
</root>
And here is the benchmark (very simple code)
var stopWatch = new Stopwatch();
stopWatch.Start();
for (int i = 0; i < 100000; i++)
{
Log.Debug("Hello");
}
stopWatch.Stop();
Console.WriteLine("Done in {0} ms", stopWatch.ElapsedMilliseconds);
Going directly through RollingFileAppender the output is :
Done in 511 ms
Whereas going through the BufferingForwardingAppender decorating the RollingFileAppender :
Done in 14261 ms
That's approx 30 times slower.
I thought I would gain some speed by buffering a certain ammount of log before writing them to the file, however for some reason it gets things much worse.
Seems to me like the configuration is OK, so this is really weird.
Anyone got a clue ?

I'm trying to use opencv to save frames from a webcam as jpgs or pngs or whatever. It's proving more difficult than I'd thought, despite having examples like the one here: http://stackoverflow.com/questions/11094481/capturing-a-single-image-from-my-webcam-in-java-or-python
I am trying to do this:
if __name__ == "__main__":
print "Press ESC to exit ..."
# create windows
cv.NamedWindow('Raw', cv.CV_WINDOW_AUTOSIZE)
cv.NamedWindow('Processed', cv.CV_WINDOW_AUTOSIZE)
# create capture device
device = 0 # assume we want first device
capture = cv.CaptureFromCAM(0)
cv.SetCaptureProperty(capture, cv.CV_CAP_PROP_FRAME_WIDTH, 640)
cv.SetCaptureProperty(capture, cv.CV_CAP_PROP_FRAME_HEIGHT, 480)
# check if capture device is OK
if not capture:
print "Error opening capture device"
sys.exit(1)
while 1:
# do forever
# capture the current frame
frame = cv.QueryFrame(capture)
if frame is None:
break
# mirror
cv.Flip(frame, None, 1)
# face detection
detect(frame)
# display webcam image
cv.ShowImage('Raw', frame)
# handle events
k = cv.WaitKey(10)
if k == 0x1b: # ESC
print 'ESC pressed. Exiting ...'
break
if k == 0x63 or k == 0x43:
print 'capturing!'
s, img = capture.read()
if s:
cv.SaveImage("r'C:\test.jpg", img)

However, after reading `info automake`, I'm still very confused about the order of which tools are invoked by the developer.
Let's think about a very simple hello world application. In the root dir of the application there is simple `src/hello.c` and nothing else. What tools need to be called in what order to create `configure` and a `Makefile`?
I figured out by myself (partially reading doc, partially just trying) that `autoscan` comes first and generates a "sketch" of the `configure.ac`. Then `autoheader` appearently creates a header file (why?). Next `autoconf` finally creates the `configure` script, which will ultimately create a `config.h`.
However, I am still missing a `Makefile` which I believe is created by `automake`, but this requires a `Makefile.am` which I don't know how to generate.

I have this list bound to a ListBox with a custom DataTemplate for the items showing the data. I also created a second page to show the details of each movie.
My problem now is the navigation between these pages. I'm using MVVM to build the applications and most of the approaches I've found searching on internet is to use the OnSelectionChanged event in the code-behind, but it goes agains what I want, that is to use MVVM.
Other approach I've seen, which is the one I'm trying, is to bind the SelectedItem to a property in the ViewModel, but I can't make it change the property, it seems that I cannot select an item in the listbox. Also, I don't have the visual feedback when I press one of the items in my listbox, like the feedback we have in the settings menu of the phone for example.
The code I'm using in the listbox is:
<ListBox Margin="0,0,-12,0" ItemsSource="{Binding Movies}" SelectedItem="{Binding SelectedMovieItem}" SelectionMode="Single" >
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<!--Replace rectangle with image-->
<Rectangle Height="50" Width="50" Fill="#FFE5001b" Margin="12,0,9,0"/>
<StackPanel Width="311">
<TextBlock Text="{Binding Name}" TextWrapping="NoWrap" Style="{StaticResource PhoneTextExtraLargeStyle}" Foreground="#000" />
<!--<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>-->
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Another approach I've seen is to use the INavigationService to achieve this, I found this article: [http://windowsphonegeek.com/articles/MVVM-in-real-life-Windows-Phone-applications-Part1](http://windowsphonegeek.com/articles/MVVM-in-real-life-Windows-Phone-applications-Part1)
I read the parts one and two, but I couldn't understand this one works.
So, what I want to know is whether the approach I'm using is the correct to make a page navigation, or if there is a better way using MVVM to do this with visual feedback on the listbox.
Thanks in advance!

Also, I don't have the visual feedback when I press one of the items in my listbox, like the feedback we have in the settings menu of the phone for example.
The code I'm using in the listbox is:
<ListBox Margin="0,0,-12,0" ItemsSource="{Binding Movies}" SelectedItem="{Binding SelectedMovieItem}" SelectionMode="Single" >
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<!--Replace rectangle with image-->
<Rectangle Height="50" Width="50" Fill="#FFE5001b" Margin="12,0,9,0"/>
<StackPanel Width="311">
<TextBlock Text="{Binding Name}" TextWrapping="NoWrap" Style="{StaticResource PhoneTextExtraLargeStyle}" Foreground="#000" />
<!--<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>-->
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Another approach I've seen is to use the INavigationService to achieve this, I found this article: [http://windowsphonegeek.com/articles/MVVM-in-real-life-Windows-Phone-applications-Part1](http://windowsphonegeek.com/articles/MVVM-in-real-life-Windows-Phone-applications-Part1)
I read the parts one and two, but I couldn't understand this one works.
So, what I want to know is whether the approach I'm using is the correct to make a page navigation, or if there is a better way using MVVM to do this with visual feedback on the listbox.
Thanks in advance!

i researched mixed values a bit and it looks like it can take in stuff like struct, arrays, int and stuff like that, but not svg. if im wrong about this plz tell me because using serialize and unserialize would make things much easier. | serialization | null | null | null | null | null | open | how to serialize svg so it can fit into a cookie

1. I have 2 web methods one to upload the raw data
2. This data is used on the server for certain calculations. i.e. An item has a set of calculations,
3. So my entity design is such that Item entity has collection of Calculation entities. The collection is not marked as a DataMember.
4. The GetItemDetails method returns each item with it's collection of calculations.
5. I have ended up defining 2 differet DataContracts for Upload and GetItemDetails operations because Item is my main entity which is used in all my business logic operations but its collection of calculations is data that gets generated at server side and must be returned on demand (GetItemDetails ). Since it's processing data it seems inappropriate to expose it at the time of Upload as no input is expected in the calculation collection.
6. In my GetItemDetails method, I use 'Item' entity and load collection of items with resp. calculation collections and then translate it into my output datacontract which has item and collection both exposed.
This approach has the disadvantage of having to maintain 2 data contracts for the same Entity representation.
I tried to search for option to dynamically adding DataMember attribute on the Calculation collection for GetItemDetails method with no success.
I hope the scenario is clear. My question is what is the best way to define data contracts in such scenarios so that client doesn't have to deal with 2 different proxy classes for representing the same entiy for Upload and Get. Will it be a correct solution if same entity is used for both so that my upload contract exposes (and then ignores any input in) Calculation collection even though user is not expected to provide it to my Upload operation ?
I will appreciate any help on this. | wcf | datacontracts | null | null | null | null | open | WCF Input/Output DataContract definition guidelines

I am looking for advice on how to connect the clients to the server.
I was thinking that I would use NetTcpBinding.
But do I use a callback structure or do I just make a netTcpBiding connection in both directions to maintain the connection?
I will probably only have about 100 online at any time, and there will be a dispatching center that would update or send the field personnel out to the client sites.
We would use cellphone data to transfer the data over the internet and a product called Netmotion that will let the client computer look like it is setting on the home network.
Any advice would be appreciated.

I think that there must be something wrong in this above Ajax Function .. but what it is that I don't know | mvc | telerik | grid | null | null | 07/24/2012 23:06:54 | not a real question | Search Telerik MVC Grid from an Ajax.BeginForm and Rebind the grid with new Model
===
I want to search Telerik MVC 2.0 Grid (aspx ViewEngine ) .. I have a " UploadFiles " View on which a Grid is rendered at first then clicking on a " Show History " Ajax.ActionLink opens a PartialView "SearchGrid " . In this View there are 2 Telerik MVC DatePickers and a submit button .. On clicking of Submit button sends DatePicker Values back to UploadFiles Controller's " SearchByDates( DateTime? frmDate,DateTime? toDate)" Action ... Here in this action I am sending frmDate,toDate Values to WorkerService Class which in turn sends values to UploadedFilesServices class ... Here in this class UploadDate Item range is matched in between frmDate and toDate ... then an IEnumerable<UploadFilesDescriptor> is sent back to UploadServices class using a LINQ query ... Result of this query is sent back to UploadFiles Controller through UploadServices , UploadWorkerServices ...Everything works fine till this point ... But My problem is with Ajax , after UploadFilesViewModel's GetUploadDescriptor is bound with UploadFilesGrid , again a call is made to SearchByDates action ... but only url.Action is called and not parameters are passed ... When at first the call to this action is made FormCollection doesn't contain anything but when next time a new call is made FormCollection values contain frmDate,toDate.. Finally an empty Grid is displayed .. I don't know what I am doing wrong ...

Because I'm not a very good coder, the way the whole thing works is that in the 'body onload' tag, there's about 15 different 'generateRandomBlah()' functions just within this one tag. The nature of the site means that on any one page, I will only need 2 or 3 of these scripts at once, but I require the ability to call *any* of them on *any* page. As you can see, my current tactic is to just call them all at once, and if the corresponding <span id> doesn't exist for a script, it'll just ignore that fact and move onto the next one.
Except that it doesn't ignore the fact that there's no corresponding
<span>.
As soon as one <span> isn't present, the rest of the scripts break and don't actually do what they're supposed to do. Looking at the code in Chrome's 'inspect code' shows an error at the first script which happens to break: "Uncaught TypeError: Cannot set property 'innerHTML' of null". I see a couple of potential solutions, but I might be completely off:
1) Add some code into each script which tells it that, if there's no <span id> on the page to insert its code, it ends gracefully and moves onto the next one - gradually (obviously in less than a second speed-wise) going through the scripts and only running them if <span id> actually exists. (As you can see, the problem is that a script will get 'snagged' on the fact that there's no place to insert its code and doesn't just end gracefully if that happens.
2) Get rid of the 'onload' stuff and just make each script self-containing, calling its own function. I don't know if this would fix the problem, though.

At the very bottom of that UIScrollView, i'm attaching a UITextView, and below that, a UITextField.
So far, so good. The contentSize of the scrollView is correctly set, and the 'scrollEnabled' flag is set to YES.
Both, the UITextView and the UITextField, have a custom InputAccesory view. It's a simple toolbar, with the previous / next buttons.
The handling code of the toolbar is the following:

// Get the firstResponder
ASSERT(_scrollView);
UIView* firstResponder = [_scrollView findFirstResponder];
if(firstResponder == nil)

}
// Do we have a nextView?
UIView* nextView = [_scrollView viewWithTag:nextViewTag];
if(nextView != nil)
{
[nextView becomeFirstResponder];
[self refreshToolbar];
}
}
I'm struggling with an ugly bug, in which... when the UITextView has several lines in it, the UIScrollView will fail to automatically scroll to the next firstResponder. (It will remain below the toolbar).
By the way, i'm handling the keyboard events, and applying a bottom inset to the scrollView, as described here: http://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html#//apple_ref/doc/uid/TP40009542-CH5-SW1.
Any suggestions / ideas will be very welcome.

Now, how can I optimize these so that they are faster? | c# | sqlite | select | null | null | null | open | c# - Optimize SQLite Select statement
===
I am using System.Data.SQLite for my database, and my select statements are very slow. It takes around 3-5 minutes to query around 5000 rows of data. Here is the code I am using:
string connectionString;
connectionString = string.Format(@"Data Source={0}", documentsFolder + ";Version=3;New=False;Compress=True;");
//Open a new SQLite Connection
SQLiteConnection conn = new SQLiteConnection(connectionString);
conn.Open();
SQLiteCommand cmd = new SQLiteCommand();
cmd.Connection = conn;
cmd.CommandText = "Select * From urls";
//Assign the data from urls to dr
SQLiteDataReader dr = cmd.ExecuteReader();
SQLiteCommand com = new SQLiteCommand();
com.CommandText = "Select * From visits";
SQLiteDataReader visit = com.ExecuteReader();
List<int> dbID2 = new List<int>();
while (visit.Read())
{
dbID2.Add(int.Parse(visit[1].ToString()));
}
//Read from dr
while (dr.Read())
{
string url = dr[1].ToString();
string title = dr[2].ToString();
long visitlong = Int64.Parse(dr[5].ToString());
string browser = "Chrome";
int dbID = int.Parse(dr[0].ToString());
bool exists = dbID2.Any(item => item == dbID);
int frequency = int.Parse(dr["visit_count"].ToString());
bool containsBoth = url.Contains("file:///");
if (exists)
{
if (containsBoth == false)
{
var form = Form.ActiveForm as TestURLGUI2.Form1;
URLs.Add(new URL(url, title, browser, visited, frequency));
Console.WriteLine(String.Format("{0} {1}", title, browser));
}
}
}
//Close the connection
conn.Close();
And here is another example that takes long:
IEnumerable<URL> ExtractUserHistory(string folder, bool display)
{
// Get User history info
DataTable historyDT = ExtractFromTable("moz_places", folder);
// Get visit Time/Data info
DataTable visitsDT = ExtractFromTable("moz_historyvisits",
folder);
// Loop each history entry
foreach (DataRow row in historyDT.Rows)
{
// Select entry Date from visits
var entryDate = (from dates in visitsDT.AsEnumerable()
where dates["place_id"].ToString() == row["id"].ToString()
select dates).LastOrDefault();
// If history entry has date
if (entryDate != null)
{
// Obtain URL and Title strings
string url = row["Url"].ToString();
string title = row["title"].ToString();
int frequency = int.Parse(row["visit_count"].ToString());
string visit_type;
//Add a URL to list URLs
URLs.Add(new URL(url, title, browser, visited, frequency));
// Add entry to list
// URLs.Add(u);
if (title != "")
{
Console.WriteLine(String.Format("{0} {1}", title, browser));
}
}
}
return URLs;
}
DataTable ExtractFromTable(string table, string folder)
{
SQLiteConnection sql_con;
SQLiteCommand sql_cmd;
SQLiteDataAdapter DB;
DataTable DT = new DataTable();
// FireFox database file
string dbPath = folder + "\\places.sqlite";
// If file exists
if (File.Exists(dbPath))
{
// Data connection
sql_con = new SQLiteConnection("Data Source=" + dbPath +
";Version=3;New=False;Compress=True;");
// Open the Connection
sql_con.Open();
sql_cmd = sql_con.CreateCommand();
// Select Query
string CommandText = "select * from " + table;
// Populate Data Table
DB = new SQLiteDataAdapter(CommandText, sql_con);
DB.Fill(DT);
// Clean up
sql_con.Close();
}
return DT;
}
Now, how can I optimize these so that they are faster? | 0 |

For simplicity, lets say a property can be represented by getter/setter functions. What I want (in simple function terms) is (inside some arbitrary class):
def setter1(self, value): self.a = value
def setter2(self, value): self.b = value
func_list = [self.setter1, self.setter2]
value_list = [1, 2]
for ind in range(len(func_list)): func_list[ind](value_list[ind])
The only thing not elegant is when I access these functions separately later on in the code. This is precisely why I want to implement a similar arrangement but with properties - so that later on in the code I still have the convenience of self.a = 1 rather than self.setter1(1). Obviously I want to ensure read only access.
I understand if this is asking too much though - just wanted to hear it from a pythonaut before I make the assumption python isn't capable. I understand the dir(), vars(), class.__dict()__ methods all return references - but correct me if I'm wrong in thinking they only return the value of the property or its string representation (I want the setter *method*).
In summary, I want the ability to pass properties like functions (in that I have full use of their methodology).
I have tried creating a function that sets the value of the property (but I get an error saying AttributeError: can't set attribute). I believe this is because only the setter function can set the value.

Sorry about all of the code. If anyone can help it will be greatly appreciated! I've gone in circles for days trying to get the ContentFlow to play nice with my session. | database | servlets | jpa | coverflow | illegalstateexception | null | open | Display db images using ContentFlow (coverflow) IllegalStateException error
===
I'm currently using a third party image coverflow (http://www.jacksasylum.eu/ContentFlow/) to display images which are being saved within a database. I'm using Java, JPA, and Richfaces for this. I have set up an image servlet to handle the image display. I have a Richfaces datatable set up and I only want to display images of selected records within the coverflow. This functionality is in place to do this. I have a command button to render the image coverflow within an OutputPanel. My images display correctly down the page without errors before implementing the coverflow. So, I know my underlying functionality works as desired. The issue is that when I implement the coverflow by placing specific div tags around my img tags as instructed I get the following error:
Error Rendering View[/index.xhtml]: java.lang.IllegalStateException: Cannot create a session after the response has been committed

i got the same result for both the OID's and that doesn't seem right. I'm wandering if there are other variables i could try instead of those i'm using now. | snmp | nagios | net-snmp | oid | mib | null | open | SNMP OID for network traffic

i'm working on a script that will monitor traffic on specific hosts from nagios. I have studied some scripts already made and have gathered almost all the info i need to do it but i have encountered a problem in identifying the OID's necessary for the traffic.
