I am having troubles, like always. For a few semester projects in school I decided to make a graphical game using the Win32 API. Things have progressed rather smoothly, but I've hit a big snag. Apparently I cannot load from a resource. Whats funny is I load my icons from the resource and that works just fine. Here is the function giving me trouble:
The commented out LoadImage call was an alternate way of trying to do this, but neither works. As to why, I dont know, my log of this spews (btw, IDB_IMAGE1 is defined as 2000):
1. Bitmap_from_resource: Beginning resource is 2357
2. IDB_IMAGE1 = 2000
3. Bitmap_from_resource: NULL bmp. Error 1812 Res: 2357
4. Loading of Image1 failed!
5. Last error: 183
Yet the way I call it is this:
So I have no idea as to why when I call the function with IDB_IMAGE1 it turns up 2357 when it is defined as 2000. The result is a resource error that will not go away.
Any ideas? See anything wrong with these functions? I'm not Win32 API expert since this is more or less my first -REAL- adventure through the Win32 API realm.
Thanks for anything and everything in advance, this is for school so I appreciate it doubly :P
