Changing the color of Rectangles
Author
In Win32 VC++ 6 How do I change the fill color of a rectangle and the border of a rectangle.
If you are doing some coding in win32 you could change the color of the rectangle by creating a brush with a different color. For the outline create a pen with a color of choice. check out

it seems to me in your code you only deleted 1 of the 2 objects you created can you explain this?
I went back and edited the code, now myPen and myBrush are both deleted. old_pen is what is initially in the hDC, just restoring it.

Also the functions are:
CreatePen(int, int, COLORREF)
CreateSolidBrush(COLORREF)
You got the names mixed up.
CreatePen(int, int, COLORREF)
CreateSolidBrush(COLORREF)
You got the names mixed up.
