Hello,

I de-installed visual studio.NET. Recently I found out that the de-installer didn't remove the JIT debugger regestry settings from my system.

Now, when a program crashes, the debug dialog appeart and asks me if I want to debug the application. When I hit the retry button (to debug), I get this really annoying message box that says that the JIT debugger canno't be found. It also asks if I want to use the old debugger msdev.exe

After sweeping the geristry manually and removing every VS.NET and JIT entry I could find, the dialog still appears.

Does anyone know how I can solve the problem?

Thanks

I solved the problem!

I just don't know why I didn't think of enabling the Just In Time debugger from VS 6.0 Mad | :mad:

On the other hand, my registry is clean(er) than it was before

Did you check this one?

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Aedebug

In "Debugger" String i have:
"C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin\msdev.exe" -p %ld -e %ld

I have the same key, but there was another key: "PreVisualStudio7Debugger". Now I have removed the key..

You never know how much garbage an uninstaller leaves around...

Hello,

I don't think that there is a function to replace a message to the top of the message qeue. But you can use SendMessage for immediate processing (the message won't be placed in the message qeue)

Check out NetUserEnum(), NetSessionEnum(), and NetWkstaUserEnum().

but it's thread application and the server was with COM technologie developed.
I use one variable iClientsCount it means how much connected clients and i would
like the show this variable in system monitor.

So iterate through each connection and increment iClientsCount. Or, you could look at the fifth parameter which receives the count of items actually iterated. What's wrong with that?

CEvent?

Please bear with me on this post, I have never coded anything in any form of C++ but my boss has given me the task of putting something together that for various reasons requires a C++ application.

The Setup
I have a C# application that launches a background process, this process has to be coded in C++. Fom time to time the C# application will need to close the background process, for various reasons I cannot do a dirty shutdown (i.e. just kill the process). So I am looking for a way of getting the C# app to make the C++ application shutdown cleanly (i.e. process some code before existing).

After doing a far bit of reading I have come across something called CEvent which I understand as being an event that can be fired by external process and caught with the C++ application.

The problem is that although I can easily hold my own in C# I havent got a clue when it comes to C++ so can anybody firstly tell me if I am on the right track, and if so can you point me in the direction of some basic tutorials.

Thanks in advance

Here are some, but not all, options:
You first need to determine how the other program will be able to respond to the request to shutdown.
1. Event: If you want to watch for an event, then you must have a WaitForSingleObject, WaitForMultipleObjects, etc. call in your C++ program. You can code in a periodic check where you can try to wait for the object for a very brief time, like 50 milliseconds or less. If it is already signaled, then you can exit the C++ program, if you get TIMEOUT, then the event was not already signaled by the C# program.
2. You might also be able to use PostThreadMessage if you had some way to determine what the main thread identifier of the C++ progrma was, then you could watch for a registered window message in the C++ progrma and terminate, or else some other message of your choosing, use the MsgWaitForMultipleObjects to get the message.
3. If the C++ program has a window and you can determine the window handle, you can then just post a WM_CLOSE to the C++ program's main window.
4. If the C++ program has a window and you can NOT determine the window handle, you can always try a SendMessage with a registered window message that the C++ program is watching for.

Thanks for the reply.

After much reading, I have opted to create an event and then sit on WaitForSingleObject(...) this works something like this :

//initialisation code
...

//create the shutdown event listener
HANDLE hEvent = CreateEvent(NULL, true, false, "EventEngine 10062004-MICRG-4546-9DD2-F0868C319D02");

//Reset the event just incase
ResetEvent(hEvent);

//sit here until the event fires (this will be initiated by the external c# app)
WaitForSingleObject(hEvent, INFINITE);

//code to cleanup and close
...

I think this will work so all I need to work out now is how to get C# to set the event, fortunately this is more comfortable ground for me Big Grin | :-D

Why o why cant I start my C++ jaunt with a nice and simple Hello World application Sigh | :sigh:
