Treatment of colors in a TStatic or TEdit class ?
How can I treat the foreground and background color
of a derivered TStatic or TEdit class in
the class himself and not the parent class ?
(With BC 4.52)
I have try to use GetDC with SetTextColor and SetBkgndColor
in the derivered TEdit class but it doesn't work.
I have also try to use the WM_CTLCOLOR in the derivered
TEdit class but the event never arrived at my TEdit class
because the parent treat this message before.
How can I activate the WM_CTLCOLOR for the derivered TEdit
class.

Use GetDC and SetTextColor and SetBkColor API functions for your classes. If it will no help handle WM_CTLCOLOR for them.

There is no way to use WM_CTLCOLOR in control itself, you have to
handle it at parent level, because each control is managed by
its parent.
add this in parent message tabel define.
EV_WM_CTLCOLOR,
add this function for control background
HBRUSH TControlParentWindow::EvCt
{
HBRUSH br = GetYourOwnControlBrush();
if(br) return br;
return TWindow::EvCtlColor(hDC, hWndChild, ctlType);
}

I doesn't want to treat the color in the parent class.

VBX make it so !!!!!
