Finish a dll

[_Carlos_]

Hello people,

I'm new programming dlls in c++, and I have one question that I don´t understand.

I have created a dll, that it's load in a thread, and then the thread finishes, I dont know how finish the dll.

I have this code in my main method:

BOOL APIENTRY DllMain( HANDLE hModule, DWORD  ul_reason_for_call, LPVOID lpReserved )
{
	switch(ul_reason_for_call)
	{
		case DLL_PROCESS_ATTACH:
			g_hModule = hModule;
			Init();
			return TRUE;

		case DLL_PROCESS_DETACH:
			Cleanup();
			return TRUE;
	}

I don´t understand when the program calls DllMain in the case DLL_PROCESS_DETACH.

Please, anybody knows??

Welcome to the Windows Forum.

What exactly do you mean "finish the dll" - release the loaded dll module? Is it not automatically released?

Welcome to the Windows Forum.

Sorry, I explain me not very well.

Yes, I mean that release the loaded dll module.

I have a thread that loads the dll, and in it, I install a hook in the beginning of the dll. When I do:

Thread.currentThread().stop();

The program in java finishes, but the dll is running during a lot of time.

To finish the dll, I need to call maindll in the case PROCESS_DETACH:

case DLL_PROCESS_DETACH:

Cleanup();

return TRUE;

because in Cleanup:

static void Cleanup()

{

if( hkb != NULL )

UnhookWindowsHookEx( hkb );

hkb = NULL;

}

Is where I Unhook, and the dll stops running.

Then, I don´t know when DLL_PROCESS_DETACH case occurs, somethig like unload, or I don´t know.

Thanks :)

Hello people!!

I have resolved it!!

The problem was that when I stop the thread it calls to the entry-point function with the case DLL_THREAD_DETACH, instead of with the case DLL_PROCESS_DETACH.

Thanks for your help :)
