Draw Resource Icon on Button - c++

Question

I would like to draw my program's icon on an "owner-drawn" button. This could be either an icon in the resource file, or the generic Windows icon. But, even after endless searching, I have not been able to find the code for this. I have come across bits and pieces of answers. But, no complete explanations.
Sorry that I have no code to post. I am totally lost on this one. Either standard Win API or GDI+ will work for me.

When you create the button, add BS_ICON style, then get the handle to your icon, you can use LoadImage.
Finally send BM_SETIMAGE message with the handle to your icon.
Here is the code sample:
HWND button1 = CreateWindow(TEXT("Button"), TEXT("OK"), WS_VISIBLE | WS_CHILD | BS_PUSHBUTTON | BS_ICON,
50, 50, 50, 50, hwnd, (HMENU)1001, hInstance, NULL);
HICON hIcon = (HICON)LoadImage( // returns a HANDLE so we have to cast to HICON
NULL, // hInstance must be NULL when loading from a file
L"iconname.ico", // the icon file name
IMAGE_ICON, // specifies that the file is an icon
0, // width of the image (we'll specify default later on)
0, // height of the image
LR_LOADFROMFILE | // we want to load a file (as opposed to a resource)
LR_DEFAULTSIZE | // default metrics based on the type (IMAGE_ICON, 32x32)
LR_SHARED // let the system release the handle when it's no longer used
);
SendMessage(button1, BM_SETIMAGE, IMAGE_ICON, (LPARAM)hIcon);
