Hello,

I've got a ATL/COM dll that has an icon: IDI_RED. I used this icon in the
dialog editor and it works. Now I want to load it with:
AfxGetApp()->LoadIcon(IDI_RED);
but it fails. When I trace inside it seems that a call to MAKEINTRESOURCE
returns 0x00000e = "" as string. This seems really strange. Any ideas?

Thank you,

Gernot

icon=LoadIcon(NULL, MAKEINTRESOURCE(IDI_RED));

returns this error:

1813 The specified resource type cannot be found in the image file.
ERROR_RESOURCE_TYPE_NOT_FOUND

Has this to do with ATL and / or DLL instead of usual exe program?

Thank you,
Gernot

... and this works!
icon = ((CStatic*)(GetDlgItem(IDC_STATIC_RED)))->GetIcon();

Ah - come on! What is going on here? I'm really desperated now.

Gernot.

Check the HINSTANCE parameter to LoadIcon. NULL refers to the main EXE;
anything else refers to a particular DLL. You obtain the HINSTANCE to your
DLL in DllMain, or through the _Module object in ATL
(_Module.GetResourceInstance() works).

Wohooo! Yes, that was it!

Also I've got a problem: when I close the dialog, which I inserted
afterwards in my ATL Dll (using CMyDlg d; d.DoModal()) after the window
closes the function CDialog::DestroyWindow fails here:
ASSERT(m_hWnd == hWndOrig);

But when I compile a release version it does not make any difference - so
why bother. But it would be nice if you know a solution to this as well...

Anyway thank you very very much,
Gernot.

Use s_hInstanceDll instead of HINSTANCE hInst = AfxGetInstanceHandle(); or NULL

example

#if (_ATL_VER >= 0x0700)
HINSTANCE s_hInstanceDll = ATL::_AtlBaseModule.GetResourceInstance();
#else // !(_ATL_VER >= 0x0700)
HINSTANCE s_hInstanceDll = _Module.GetResourceInstance();
#endif // !(_ATL_VER >= 0x0700)

hBitmap = HBITMAP( ::LoadImage( s_hInstanceDll,
MAKEINTRESOURCE( IDB_BITMAP_NO_VIDEO ),IMAGE_BITMAP,0,0,
/*LR_LOADFROMFILE|*/LR_CREATEDIBSECTION ) );

If you're going to reply to a thread from over a decade ago, at least
quote some context please.
