I've been trying to load a bitmap from my resources in order to set it as an icon in one of my programs control for a good while now, with no success at all.
What I did so far:
First, I went into the code of my .rc file, and added all my bitmaps like this in the corresponding BMP section. Note that all .bmp files are saved as 256-color-bitmaps:
IDB_01d BMP "<path>"
Afterwards, I went into my Resource.h file and inserted a define for every bitmap, looking like this:
#define IDB_01d 2000
After adding my resources, this is what I tried in my code so far:
HBITMAP hbmp = LoadBitmap(m_hInstance, MAKEINTRESOURCE(IDB_01d));
DWORD lastError = GetLastError();
m_weatherIcon.SetIcon(hbmp);
Note that m_hInstance is the HINSTANCE i got from my _tWinMain-method.
However, this is not working. The problem is currently the fact, that hbmp is NULL, due to LoadBitmap returning a NULL value.
I added a call to get the last error, and the error code I'm getting is 1813 all the time. I already did some research, and it seems like the HINSTANCE might be the problem, but I don't see how exactly.
Any advice?
