Hey, i have a listbox that contains various items inside of it. can someone tell me how i can make only one of those items selected in the listbox, be deleted by pressing a button?

You want to have exactly one string in listbox? Or one selected string in listbox?

I want to be able to select one item in the the list box and remove it from the list with the push of a button.

CListBox::SetCurSel selects item (assuming that you have single-selection listbox). CListBox::DeleteString deletes item with specified index.

Hi Tomasz
This thread is now dead. The question has been reposted and using my nick in the subject. The nick was spelt wrong and I had to replace a { with a [ in the reply. But I think the subject of the re-post might actually confuse some people and they might think I am deleting strings for whatever reasons I might have

I am learning multithreading for the first time. I tried to create a thread using CreateThread() in MS Visual C++:
sThread = CreateThread(NULL, 0, StreamHandler, NULL, 0, &sThreadID);
Tracing through debugger, the thread seems to be created because I receive a handle.
I placed a cout statement at the beginning of my StreamHandler function, but it was not printed. So it seems as if the thread was created, but did not execute my function.
Does anyone know how I can jump into my function to see if the thread is running?

cout uses C++ runtime features, which are not initialized when you create thread by calling Win32 API (CreateThread). If you want to use streams or anything which is provided by runtime, you need to create your thread with _beginthread or _beginthreadex.

Use _beginthreadex instead. The CreateThread function don't initialize the CRT (C-RunTime, not Cathodic Ray Tube  correctly, so this might be your problem.

** OK, let's assume I don't use cout, but printf instead **
How do I use the Visual Studios so I can trace into my thread function?

Just set a break point in your thread routine.

I did that. It didn't go into the thread function.

Strange, very strange...
Maybe someone else has seen this before. Like you, since it created the handle, the thread was at least started. I would have expected some type of dialog box if it tossed an exception.
When you call CreateThread, are you having to do any type casting to get the routine to accept your routine?

This is my code:
DWORD WINAPI StreamHandler(LPVOID lpParam)
{
//Thread function code
printf("I am in the thread\n");
}
//Create TCP/IP Thread
sThread = CreateThread(NULL,0,StreamHandler,NULL,0,&sThreadID);
if (sThread == NULL)
cout << "Create Stream Thread Failed\n";
else
CloseHandle(sThread);
It's pretty simple, I don't know why it doesn't execute.

Something else is going on. I just tried that code and it worked just fine.

Hmm, are you exiting your program right after the create thread?
If so, then your thread probably doesn't even have the chance to execute.

That is what I realized too. Hopefully there is more to the program than just those lines.

Yes, but he called CloseHandle right after creating the thread

It doesn't stop the thread. I found much evidence on groups.google.com that if you don't care about syncing on the handle, then closing it right after creation is very common.

I do end the program after I create the thread what do I do to give it time to execute? No one mentioned this when I was reading up on threads...
What should I do put a sleep in?
|
|
|
|
|
Did that work for you? I received some kind of memory leak... Does this sound familiar?

cout, printf, same sh*t. As a matter of fact, cout uses printf to perform its job (or at least fome function from stdio.h.

Just forget CreateThread, and use _beginthreadex instead.
