So I'm giving it a test run now. I have no problem running my test project. However I'm not entirely sure if I'm doing it right. Mainly because I don't really understand what is happening exactly( at least im not entirely sure).
I've compiled both the DLL and Static library(.a). For my test project i'm using the Headers from my library and linking against the static library. I'm able to compile. But then It seems that I also need the DLL where the executable resides in order for it to run.
So to my understanding, I compile using the static library but I don't exactly embed it into my executable, therefor at runtime it's looking for the DLL?
My confusion comes from the fact that I read that static libraries are usually embedded into the executable. But doesn't that only happen if you specify that in the compiler options?
I'm rather confused about the relationship in my sittuation. Can someone clarify this? | c++ | dll | static | compilation | null | null | open | C++: Static and Dynamic libraries ( compiling and running)

A key requirement is view-level auditing. In other words, we must be able to show who accessed a view, the parameters to create the view and when the view was accessed.

My problem is this, when querying from the local machine through remote desktop, querying for www.domainname.com/Content/Styles/reset.css i get the css fine.
When doing the same from an external machine, I get a 404 error... I know why, the reason is that it's trying to get the file from:
C:\inetpub\wwwroot\Content\Styles\reset.css
This is kind of bad considering that the website is actually hosted at: c:\http\www.domainname.com\
The error in the browser, from IIS, gives the following information:
Module IIS Web Core

Handler StaticFile
Error Code 0x80070002
Requested URL http://www.domainname.com:80/Content/Styles/reset.css
Physical Path C:\inetpub\wwwroot\Content\Styles\reset.css
Logon Method Anonymous

I've been looking at the other sites running on the IIS, and none of them point to InetPub as their directory, so I simply can't see why it's trying to get the item from this path.
Calling the main application, a MVC based site running Umbraco, works fine, or rather, all the dynamic content works fine, just not static content.
To give a little more information:
Currently the IIS 7.5 has 4 sites and 1 ftp server running.
1 site with the following bindings:
http - this 1st site host name - port 80 - ip address *
https - blank host name - port 443 - ip address *
1 site with the following bindings:
http - the 2nd site host name - port 80 - ip address *
1 domain with the following bindings:
http - the 3rd site host name - port 80 - ip address *
The actual domain
http - www.domainname.com - port 80 - ip address *
And finally a ftp server
I hope that someone have any idea what is going on...
Best regards and praying (despite being an atheist),

On testing of OpenPGM with pgm_send and pgm_recvfrom, The situation is I am sending the package between a Windows 7 computer and a Windows XP computer. They are connected directly and only to a gigabits switch.I got following problems:
1. Windows 7 does not receive any data on application layer, even though I did see data arrived from its wireshark log.
2. unrecoverable data loss, I tried to send data from a Windows 7 to Windows XP computer. Data packages arrived, but after about 10KB, unrecoverable data loss came.
Data packages got lost in transfering, NAK is sent from receiver to sender, sender also received the NAK, which I can see from wireshark log.
But it seems the sender does not react on the NAK, I did not see any NCF log.
- I tried to introduce the speed limit, it did not work until I reduced it to 1500 bits.
- I tried to introduce sleep between pgm_send, it worked when I added a sleep(500) for each 10KB.
From the announcement of OpenPGM, it is stated achieve a speed of 700mb/s.
So I am not sure if something is missing in my implementation. Is there any specific configuration for responding on NAK?

| c++ | multicast | pgm | null | null | null | open | unrecoverable data loss of OpenPGM on Windows 7
===
I recently started to try the OpenPGM out for a distribution feature, which basically needs to transfer data to multiple receivers.
On testing of OpenPGM with pgm_send and pgm_recvfrom, The situation is I am sending the package between a Windows 7 computer and a Windows XP computer. They are connected directly and only to a gigabits switch.I got following problems:
1. Windows 7 does not receive any data on application layer, even though I did see data arrived from its wireshark log.
2. unrecoverable data loss, I tried to send data from a Windows 7 to Windows XP computer. Data packages arrived, but after about 10KB, unrecoverable data loss came.
Data packages got lost in transfering, NAK is sent from receiver to sender, sender also received the NAK, which I can see from wireshark log.
But it seems the sender does not react on the NAK, I did not see any NCF log.
- I tried to introduce the speed limit, it did not work until I reduced it to 1500 bits.
- I tried to introduce sleep between pgm_send, it worked when I added a sleep(500) for each 10KB.
From the announcement of OpenPGM, it is stated achieve a speed of 700mb/s.
So I am not sure if something is missing in my implementation. Is there any specific configuration for responding on NAK?

I know it is less than ideal to work on a remote repository but is there a way to have Aptana recognize remote git repositories and have the git commands enabled for them as well? | 0 |

I'm creating some HTML elements on-the-fly like this:
Element outerDiv = DOM.createDiv();
outerDiv.getStyle().setOverflow(Overflow.HIDDEN);
outerDiv.getStyle().setWidth(100, Unit.PCT);
outerDiv.appendChild(new HTML(mapPOI.getHtmlDetails()).getElement());
Button popupButton = new Button("View Property");

Then I'm getting the source HTML for these elements by calling
String src = outerDiv.toString();
and inserting this html into my map marker. Now my map marker displays the content ok, including the button. However, the button won't respond to any events! From what I can gather, this is because the buttons onAttach() method is never being called.
Is there a better way to do this?

Is there a way to tile a bitmap along a Rect object using a paint property or something? I have looked, but I can't find anything that makes it do what I need it too, most of the tiling options won't tile it for a specific instance, they tile it along the entire screen, so everything using that bitmap ends up having one big bitmap tiling along all of them at the same time, without scrolling or anything.
Any ideas? If you need more info let me know, its kind of a weird question so I know I probably didn't mention something important.

Essentially, I want to send a record across (using a stream) but this record can indicate that x bytes to follow will be an image file.
As such, when the record is recieved on the server, if it's contents indicate it's followed by an image, it needs to separate the record and image data.

//The Size of the stream is 8 bytes here!

end;
To simulate the 'image file' I simply want to send TWO records consecutively; thats the aim. Notice here I am sending the whole memory stream at once (!) and NOT record by record. But interestingly, the server runs the OnExecute event twice!

I want it to execute once, so in the future I can first read the header record (known size) and THEN see what/if anything is to follow and act accordingly..
Help would be greatly appreciated!

In summary, I wish to identify a pattern (e.g. `**/*ResourceTest.java`) that describes the tests I don't want to run, unless I pass a Maven property to enable them.
E.g.
`mvn clean install` (*runs the standard tests, but skips resource tests*)

The left-hand panel is fixed-width, and docked to the left of the form. It works fine, and isn't relevant here.
The right-hand panel is positioned to the right of the left-hand panel, filling the remainder of the form, and anchored top, left, bottom & right so that, as the form resizes, it continues to occupy the whole of the form except that part occupied by the left-hand panel. It also has `AutoScroll` set to `True` so that whenever the content is too big to fit, it automatically displays scrollbars. That part works fine too.
Because I want to show different things in the right-hand panel at different times, I've created an ordinary `Panel` as a container, and am using child panels for each of the different types of content. Only one of these child panels will be visible at any one time.
One of the things I (sometimes) want to display in the right-hand panel is a very much like the "icon" view in Explorer - i.e. a bunch of file icons, and for this a `FlowLayoutPanel` sounds perfect, since I do want them to be arranged left-to-right but then wrapping onto a new row as required.
I would have thought this was exactly what a `FlowLayoutPanel` was designed for, but I can't get it to work! [I set the `Dock` property of the `FlowLayoutPanel` to `Fill` so that it uses all the space available in the parent `Panel`.] What actually happens is that it just displays all the icons in a single row, and never wraps them. I end up with a horizontal scrollbar on the parent `Panel` because the `FlowLayoutPanel` does not fit.
I think this might be because the parent `Panel` that contains the `FlowLayoutPanel` does not have a fixed size (since it will grow and shrink with the form), and so I guess when the `FlowLayoutPanel` decides how wide it can afford to be, it decides that it can be as wide as it likes. However, that's not very helpful.
Is there any way I can persuade the `FlowLayoutPanel` that it should only be as wide as its parent `Panel`? | .net | winforms | flowlayoutpanel | null | null | null | open | Can a FlowLayoutPanel auto-fit to a resizable panel?

The credit tables are as follows:

| id | user_id | coins | timestamp |
+----+---------+-------+---------------------+
credit_spend
+----+---------+-------+---------------------+
| id | user_id | coins | timestamp |

What I'm trying to do is select the SUM(credit_purchase.coins) - SUM(credit_spend.coins) for each user. Right now I have something like this:
SELECT users.*, COALESCE(SUM(credit_purchase.coins) - SUM(credit_spend.coins), 0)
FROM users
LEFT JOIN credit_spend ON users.id = credit_purchase.user_id
LEFT JOIN credit_spend ON users.id = credit_spend.user_id
GROUP BY users.id
but, it the result is not the correct number. It seems to be SUMing the purchases properly, but multiplying the SUM from the spend by the number of purchases.
What am I doing wrong?

I've started a git repository of a framework I'm developing which is used on a lot projects I'm working on, to update these projects easily.
To test, I've started a new project and added the framework as a submodule. I've cloned the project on a new folder, executed the following commands `git submodule init; git submodule update` and the submodule was cloned into it's directory perfectly.
After that, I've made some modifications to the source accordingly to the project needs and committed the modifications made on the source and pushed to the server. Everything went fine.
On the another folder which I've cloned, I've pulled the modifications and everything seems to be ok.

When I test in Fiddler, I specify the verb as GET, and enter the JSON text in the "Request Body" input box. This works great!
The problem is when I attempt to perform Load Testing in Visual Studio 2010 Ultimate. I am able to specify the GET action and the JSON Content-Body just fine. But when I run the Load test, VS reports exceptions of type ProtocolViolationException (Cannot send a content-body with this verb-type) in the test results. The test executes in 1ms so I suspect the exceptions are causing the test to immediately abort. What can I do to avoid those exceptions?

When I test the sdk with the obfuscated jar that ProGuard spits out, the graphical layout editor in Eclipse says that it cannot find the class:
The following classes could not be found:
- com.my.company.PublicViewClass (Fix Build Path, Edit XML, Create Class)
The jar is indeed included on the build path of the project's properties and marked for export, but the editor can't seem to find the class.
This is not a null pointer exception nor is this a build error. The test project that I created builds and runs fine, finding `PublicViewClass` properly. A placeholder shows up in the layout editor for that class, but that "error" message shows up under the sample view.
The XML layout file is using the class's full path:
<com.my.company.PublicViewClass android:layout_width="200dp"
android:layout_height="200dp"
android:layout_marginTop="10dp"
android:layout_gravity="center"/>
I'm using ADT 18 and the test Android project is targeting Android 2.1.

[1]: http://www.cs.utexas.edu/~moore/publications/fstrpos.pdf
Almost everyone knows how Boyer Moore and Knuth Morris Pratt algorithm works. I recently looked into BM algo and i looking at how the delta1 and delta2 tables are formed, the logic behind it. The explanations and examples are understandable but the RPR table that is rightmost plausible reocurrence table manipulation is not explained well anywhere.
The paper says
delta2(j) = patlen + 1 - rpr(j)
but the calculation of rpr is still not vivid. i have gone through many articles on internet and still nothing is upto the mark. | boyer-moore | null | null | null | null | null | open | Boyer Moore Algorithm Delta2 Table

I have tried so much already and used google i just seem to continually receive syntax errors and unexpected at this time errors, dos is really a struggle to trouble although it is pretty old and yet powerful.
my structure was like :
echo off
if "%1"=="imre" goto imre (
echo found parameter "%1"
) else if NOT %1=="imre" echo you failed
just not working i get ( was unexpected and other syntax errors if i try to tweak this...
its not exactly what i want though because i have manipulated it so many times.
All i want is to:
if %variable%=="hello" (
echo hello is correct
echo now lets start this program
start /w excel.exe
) else (
exit 1
)
this does not work, i dont understand what i am doing wrong.
