Hi Giovanni,

My module is a filter to work with DirectShow. Now i used
::GetModuleInstance(sMyModuleFileName), it fixed my problem.

Hi all

i try to load a bitmap from resource in COm and dll.
hInstance = NULL;// i can't get instance
LoadBitmap(hInstance, ID_BITMAP1)

Hi,

I don't know if I have understood your question well...

However: when a DLL is loaded into a process, the DllMain function is
called with dwReason == DLL_PROCESS_ATTACH, and the DLL hInstance is
specified as input parameter to DllMain.
So, you can store the DLL instance like so:

<code>
BOOL WINAPI DllMain(
HINSTANCE hInstance,
DWORD dwReason,
LPVOID lpvReserded )
{
switch ( dwReason )
{
   case DLL_PROCESS_ATTACH:
   {
     // Save DLL instance handle
     g_dllInstance = hInstance;
     break;
   }
   ...

}

return TRUE;
}

</code>

If you use ATL, you might use CComModule::GetModuleInstance (or use
CAtlBaseModule, if you are developing using ATL 7).
