Var
    Hcol: HDC;

Begin
 Hcol:=GetWindowDC(HandleOfEditBox);
 SetBkColor(HCol,RGB(255,0,0));
 SetTextColor(Hcol,RGB(255,0,0));
End;

Ok any idea why this does not work?

It may be that you are not drawing to the edit box eith the nex settings because this chages the text.

procedure TForm1.Button1Click(Sender: TObject);
Var
  Hcol: HDC;
  mystr : array [0..5] of char;
Begin
 mystr:='abcdef';
 Hcol:=GetWindowDC(Edit1.Handle);
 label1.caption:=inttohex(hcol,8);
 SetBkColor(HCol,RGB(0,100,0));
 SetTextColor(Hcol,RGB(128,0,0));
 TextOut(Hcol,0,0,myStr,5);
 ReleaseDC(Edit1.Handle,Hcol);
end;

get the text and re draw it, you could maybe use the invalidaterect call to force a redraw or just do this

 Hcol:=GetWindowDC(Edit1.Handle);
 SetBkColor(HCol,RGB(0,100,0));
 SetTextColor(Hcol,RGB(128,0,0));
 GetWindowText(Hcol,myStr,6);
 TextOut(Hcol,0,0,myStr,5);
 ReleaseDC(Edit1.Handle,Hcol);

This is strange , when you set the backgroud color the systems reports it as changed to
the new value .

It looks like you are only changing the windows context and this may be causing the delphi edit box to re paint to the original settings.

You amy have to create the edit box using windows calls instead of delphi calls to do what you want to do.

I use CreateWindowEx to make my edit control, there are no params to set the color of the edit box, you should be able to take the handle of the edit box (from any application) and with nothing more than the handle change the edit color box like doing...

EditBox1.Color:=$FF00FF;

That's all i am trying to do but in Win32 API
