Color window in hbrBackground

Question

WNDCLASS wc;
...
wc.hbrBackground = (HBRUSH)GetStockObject(COLOR_WINDOW+1);

I could not undestand what is +1 for and what is HBRUSH?

Answer 1

Don't you mean?

wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);

GetStockObject gets one of the stock brushes, pens, fonts or palettes. You should not be using COLOR_WINDOW with it.

Use one of the stock brushes with it, so for a white background you could use...

wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);

Whatever works, use it!
