The communication between those sites and the CRM instance is done via a **CRM proxy**, a WCF service that sits near it (near CRM), handles requests, queries CRM etc.
That WCF service is facing the Internet. Although secured communication channels aren't that necessary, authentication is. We cannot let random clients to use the services provided by the CRM proxy.

Here is the relevant code snippet.
>new=$(sed -n '/version: /p' temp.txt)
sed -i .bk "s/version: [.0-9]*/version: $new/" file2.txt
The problem I'm having is that the variable `new` doesn't take just the one line with the version number on it, but instead takes the whole file, file2.txt. This leads me to believe that the `-n` part of the command isn't working, as this should suppress the printing of all lines but those with the string `version` in them.
I think this could be a problem with the version of sed I am using (on a mac). Alternatively I could be using the sed command wrong. Any help would be appreciated.
I'd rather not update my version of sed, since this script will not just be running on my computer. So any workarounds would be ideal.

}
So the switch appears on the overlay, but how do I command it do something when called?
I've tried the following
-(void)mySwitch {
if ([mySwitch.on]){
execute this..
}
}
But the above doesn't work. I get an error saying "undeclared identifier, did you mean UISwitch?". So then I replace mySwitch.on with UISwitch.on, then it says " property on not found on object of type UISwitch".
I just want to execute my if else method properly. I made the overlay, I made the switch code and it appears on the overly perfectly. But now I want it to do something with an if/else condition. How do I rectify this?
What did I do wrong?

However I cant seem to be able to print an single element.
p array2D[0][0]
gives me
> Cannot perform pointer math on incomplete types, try casting to a known type, or void *.
I tried to google this but I can't find anything and I am not sure if I am missing something obvious. | 0 |

The problem I have, is that for obvious reasons since the I/O is blocking there can only be one connection to the socket at any one time that PHP is able to manipulate. I am fine with this, as this is the behaviour I am after.
However, if a client is to open a connection to the my PHP server, if they are simply leaving the socket open and sending no data, the socket and daemon are rendered useless as the blocking I/O will not allow new requests.
Is there a way to detect a client that is simply sending no data (like a no-transmission timeout) or something similar? I'd rather not use non-blocking I/O. | php | sockets | tcp | null | null | null | open | PHP Socket Blocking

Does someone know why it works only on simulator as I expected? BTW, I'm using the SDK for iOS6, Can it be something there?

I'm having something really weird going, I'm adding caption to an image and everything works fine on simulator but on the device itself the font is really small...
I have a problem when using this code :
-(UIImage*) drawTextOnPic:(NSString*) bottomText
inImage:(UIImage*) image
{
UIFont *font = [UIFont boldSystemFontOfSize:CAPTION_FONT_SIZE];
UIGraphicsBeginImageContext(image.size);
[image drawInRect:CGRectMake(0,0,image.size.width,image.size.height)];
CGRect = CGRectMake(10.0f,10.0f,image.size.width-20.0f, image.size.height);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetShadow(context, CGSizeMake(2.5f, 2.5f), 5.0f);
[[UIColor whiteColor] set];
[bottomText drawInRect:CGRectIntegral(rect) withFont:font lineBreakMode:UILineBreakModeClip alignment:UITextAlignmentCenter];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}

My goal is to read EXIF metadata of a jpg picture.
There are some tutorials on the internet, but I have some difficulties with them.
1)
I found this code on a msdn man page, its about the use of GDI+ library and functions of a Bitmap class..
'Create an Image object.
Dim image As Bitmap = New Bitmap("c:\FakePhoto.jpg")
'Get the PropertyItems property from image.
Dim propItems As PropertyItem() = image.PropertyItems
'Set up the display.
Dim font As New Font("Arial", 12)
Dim blackBrush As New SolidBrush(Color.Black)
Dim X As Integer = 0
Dim Y As Integer = 0
'For each PropertyItem in the array, display the ID, type, and length.
Dim count As Integer = 0
Dim propItem As PropertyItem
For Each propItem In propItems
e.Graphics.DrawString( _
"Property Item " & count.ToString(), _
font, _
blackBrush, _
X, Y)
Y += font.Height
e.Graphics.DrawString( _
" iD: 0x" & propItem.Id.ToString("x"), _
font, _
blackBrush, _
X, Y)
Y += font.Height
e.Graphics.DrawString( _
" type: " & propItem.Type.ToString(), _
font, _
blackBrush, _
X, Y)
Y += font.Height
e.Graphics.DrawString( _
" length: " & propItem.Len.ToString() & " bytes", _
font, _
blackBrush, _
X, Y)
Y += font.Height
count += 1
Next propItem
'Convert the value of the second property to a string, and display it.
Dim encoding As New System.Text.ASCIIEncoding()
Dim manufacturer As String = encoding.GetString(propItems(1).Value)
e.Graphics.DrawString( _
"The equipment make is " & manufacturer & ".", _
font, _
blackBrush, _
X, Y)
But is this possible to use in VBA? I added System_Drawing resource, it knew Bitmap class, but I couldnt use PropertyItem() for example.. what am I doing wrong please?

I know its probably lame question, but i wasnt able to find an answer (at least if you told me where to find answers it would be great :) | excel | vba | metadata | jpg | basic | null | open | Visual Basic for Application (Excel 2002): How to use WIC api or Bitmap class?
===
I have no experience with VBA and I need to get this done. I appreciate any help.
My goal is to read EXIF metadata of a jpg picture.
There are some tutorials on the internet, but I have some difficulties with them.
1)
I found this code on a msdn man page, its about the use of GDI+ library and functions of a Bitmap class..
'Create an Image object.
Dim image As Bitmap = New Bitmap("c:\FakePhoto.jpg")
'Get the PropertyItems property from image.
Dim propItems As PropertyItem() = image.PropertyItems
'Set up the display.
Dim font As New Font("Arial", 12)
Dim blackBrush As New SolidBrush(Color.Black)
Dim X As Integer = 0
Dim Y As Integer = 0
'For each PropertyItem in the array, display the ID, type, and length.
Dim count As Integer = 0
Dim propItem As PropertyItem
For Each propItem In propItems
e.Graphics.DrawString( _
"Property Item " & count.ToString(), _
font, _
blackBrush, _
X, Y)
Y += font.Height
e.Graphics.DrawString( _
" iD: 0x" & propItem.Id.ToString("x"), _
font, _
blackBrush, _
X, Y)
Y += font.Height
e.Graphics.DrawString( _
" type: " & propItem.Type.ToString(), _
font, _
blackBrush, _
X, Y)
Y += font.Height
e.Graphics.DrawString( _
" length: " & propItem.Len.ToString() & " bytes", _
font, _
blackBrush, _
X, Y)
Y += font.Height
count += 1
Next propItem
'Convert the value of the second property to a string, and display it.
Dim encoding As New System.Text.ASCIIEncoding()
Dim manufacturer As String = encoding.GetString(propItems(1).Value)
e.Graphics.DrawString( _
"The equipment make is " & manufacturer & ".", _
font, _
blackBrush, _
X, Y)
But is this possible to use in VBA? I added System_Drawing resource, it knew Bitmap class, but I couldnt use PropertyItem() for example.. what am I doing wrong please?
2)
Second tutorial I found was about Windows Imaging Component (its not VB, but I couldnt get it work in C# also).
First code on that page is:
IWICImagingFactory *pFactory = NULL;
IWICBitmapDecoder *pDecoder = NULL;
IWICBitmapFrameDecode *pFrameDecode = NULL;
IWICMetadataQueryReader *pQueryReader = NULL;
IWICMetadataQueryReader *pEmbedReader = NULL;
PROPVARIANT value;
// Initialize COM
CoInitialize(NULL);
// Initialize PROPVARIANT
PropVariantInit(&value);
//Create the COM imaging factory
HRESULT hr = CoCreateInstance(
CLSID_WICImagingFactory,
NULL,
CLSCTX_INPROC_SERVER,
IID_IWICImagingFactory,
(LPVOID*)&pFactory);
// Create the decoder
if (SUCCEEDED(hr))
{
hr = pFactory->CreateDecoderFromFilename(
L"test.jpg",
NULL,
GENERIC_READ,
WICDecodeMetadataCacheOnDemand,
&pDecoder);
}
// Get a single frame from the image
if (SUCCEEDED(hr))
{
hr = pDecoder->GetFrame(
0, //JPEG has only one frame.
&pFrameDecode);
}
and I just dont know what reference to add (i tried windowscodecs.dll - wrong move) or what Declaration to add to get the VBA module to know this *IWICImagingFactory* (for example), can you help me?

I have N databases with similar structures and I access it with EJB module in GlassFish 3.1.1. Some of my EJB methods are secured (@RolesAllowed...). I want simply test theses methods with remote call by an application client with JNDI. I can access remote interface of my bean with InitialContext().
But now I'm a litle bit lost because I don't know how to call these secured methods with correct Identity to match secured role of the method.
Should I create new realm or only JAAS module ? I'm in doubt...
Actual Glassfish jdbcRealm doesn't match my case because I want user to provide username, password AND database name to get identity but jdbcRealm is mono-database...
For now, I have created one JAAS test module in my EJB module and created one method to launch authentication process. Authentication seems to finish well and I had one Principal to my Subject on commit method :
@Override
public boolean commit() throws LoginException {
if(succeeded){
subject.getPrincipals().add(new OlivierPrincipal(name));
}
return succeeded;
}
name variable equals "name" String and I have created glassfish-ejb-jar.xml in which I wrote :

ejb.testLogin(); // test login with JAAS module stored on my EJB module

I have some security error because my method call isn't done with admin role.

I currently have a view controller called `MainViewController` which has a UITableView with many different cells. When I click on a cell, I want that cell to expand (grow in height) and show some "additional information". The problem is, this additional information is very complex and can contain UILabels, other UITableViews, UIWebViews and UIImageViews. Furthermore, this "additional data" requires quite a bit of computation in order to determine what exactly to display (i.e. what the UILabels say, how large the UIImageViews are). Therefore, because of the complexity of this "additional information", I'm at a loss as to how to design my program.
The "additional information" requires a lot of code, thus I don't want to just throw that code into the `MainViewController.` Additionally, it would be nice if there was some way to use Interface Builder to design these "additional information" views graphically rather than programatically.
Currently I have each set of additional information as its own separate UIViewController (thus allowing me to have separate classes for the data and allowing me to use interface builder) and I just segue to a new screen when a cell is selected. However, I don't want to segue to a new screen; I want all of the data that this UIView controller is showing to be shown in `MainViewController`. What's the best way to do this?
In summary, I currently have one UIViewController segueing to another UIViewController; however, I want the second UIViewController's content to be show in the first. If possible I would like to use some sort of Interface Builder and to separate out the logic for this second UIViewController into another class.
Details:
~ I'm developing for iOS 5 only and I'm using ARC.

A = "cheddar".split(//) # ["c", "h", "e", "d", "d", "a", "r"]
B = "cheddaar".split(//) # ["c", "h", "e", "d", "d", "a", "a", "r"]
The A array is a subset of the B array. If the A array had another "d" element, it wouldn't be a subset.
I want to compare and find if one is a subset of the other even if they have duplicates. The A - B or the A & B doesn't capture the duplicates it just compares them and find them matched. So I wrote the following which it captures the duplicates:
B.each do |letter|
A.delete_at(A.index(letter)) rescue ""
end
p A.empty?
Is this the best way or can it be optimized?

For example, I could sum the cash of all agents in an array using the following:
sum_of_cash = agents.inject(0) { |sum, e| sum + e.cash }
However, how can I sum only the positive or negative values of the properties, i.e. only the positive or negative cash balances, for example?
One way I can think of is doing a loop over the array and summing only if the value is positive using an if function but I'm looking for a cleaner method, if possible.

The three data tables in question are **Users**, **Roles** and **Pages**, with the two link tables **UserRoles** and **RolePages**. These tables are related thus:
- a **User** has many **UserRoles**
- a **Role** has many **UserRoles**
- a **Role** has many **RolePages**
- a **Page** has many **RolePages**
The Catalyst helper script created these relationships and accessors for me:

"MyApp::Schema::Result::UserRole",
{ "foreign.username" => "self.username" },
{ cascade_copy => 0, cascade_delete => 0 },

My end goal is to have a clean way to get a list of the pages that should be displayed for the current user. I.e.:

{
'username.username' => $self->username,
},
{
join => [
{

},

],
}
);
}
which worked until I added a class to extend MyApp::Schema::Result::RolePage. That class starts off like this:
package MyApp::Schema::ResultSet::RolePage;
use Moose;
use namespace::autoclean;
extends qw/MyApp::Schema::ResultSetX::DisplayTable/;

I've used this technique throughout my app, to create various result sets, and have only run into trouble with it now. I get this error:

We may have our peon about to reach the end of the board, and it may be required for a method called onto that peon object to change the class of that object to 'Queen', 'horse' or whatever.

Serializing the tree to an HTML string should be relatively forward, normally, since the tree nodes store information about offsets and lengths from the original HTML document, to be able to reproduce the exact same string, byte by byte.
However, when one has manipulated the tree with `append_child` and `erase` and so forth, that information quickly becomes useless since the original document, obviously, doesn't contain anything regarding new nodes.
How would one go about reconstructing the HTML from this tree?
The tree contains `HTML::Node`s and they contain information about one DOM node (tag, text, comment).
The tree class has [several iterators available][3] for traversing the tree.

I noticed that loading the audio files from a second device doesn't work immediately. So I implemented
- (BOOL)downloadFileIfNotAvailable:(NSURL*)file
That helped but still it works sluggish.
I wanted to speed up the downloading process on other iCloud devices by wrapping the audio file in a UIDocument. Is this even possible? I could store the file contents in a NSData, but is there a point (seeing as how AVAudioPlayer wants a URL)? Is there another way for me to speed up the synchronization?
Thanks

I have a little app that works with iCloud. It stores audio files into the cloud. I noticed that loading the audio files from a second device doesn't work immediately. So I implemented
- (BOOL)downloadFileIfNotAvailable:(NSURL*)file
That helped but still it works sluggish.
I wanted to speed up the downloading process on other iCloud devices by wrapping the audio file in a UIDocument. Is this even possible? I could store the file contents in a NSData, but is there a point (seeing as how AVAudioPlayer wants a URL)? Is there another way for me to speed up the synchronization?
Thanks

I've read about disabling binary log when restoring a DB dump, but I can't find how to do this with general log (all the INSERT statements end up there and they take a lot of space). Is it possible to disable this kind of logging just for the restore operation?
