Windows 7
I create parent window(size 800x600) and create WS_CHILD+WS_VISIBLE button(position 200,200 and size 80,30 ).
And GDI+ draw on button png picture. Work well.

But around the button exists white rect.
How disable\hide this rect ?

I try BS_FLAT not help.

Can we see a screenshot? Isn’t this some kind of off-by-one mistake in drawing operations?

But on button we see white rect. Button not push on image !
If button pushed with rect draw tab stop lines ! It's horrible! Shocked

I do trick.
Create parent window smaller than button !
And rect not draw becoase pass in not render parts of parent window.
But this trick bad if we want draw many buttons on one parent window.
