Dialog control - add color border when focused

[r0n]

Sorry again for this simple question.
I am looking for a way to give an interface element-border a different color (example: text-inputfield).
(see code below)

• I tried the 'DrawFocusRect'
  http://msdn.microsoft.com/nl-nl/library ... 85%29.aspx
  But I coudn't get it to render a focus-rectangle around a text-inputfield
  
  
• I also tried to find something in the MSDN 'windows styles' here:
  http://msdn.microsoft.com/en-us/library ... 85%29.aspx
  But the problem here is that most styles can't be modified after the window has been created.
  
  
• I also tried the on screen drawing of an rectangle:
  Drop Box for OCR
  On-screen drawing
  But the problem is that it is time constrained (rectangle is drawn for an amount of seconds/minutes/...).
  I need to keep it 'on' until the user switches to another interface element (or does something else).

To summarize, I am just looking for a very simple way to change the border color of an interface element.
Or change the borderline/border color of the "Group, or multi-drag container", in that way I just place the around the interface-object(s)
(see code below)
