Thank you . I will Replace this code & use.

My requirement is , My dialog box background colour is black [ RGB(0, 0, 0) ] & Text colour is Green [ RGB(128, 255, 0) ].

So i try to change the all controls edit box, picture box & button, etc.. colours into the same dialog box's background colour (Black).

And also I'm used the same background colour & text colour for all my child dialog & controls in my project.
