How Would I Do This...

How can I use SendMessage API to change the Appearance from 3D to Flat on a RichTextBox at runtime? What Message do I send to change the style/appearance?

Here's a list of messages to change window style

I think you have to take out the WS_EX_CLIENTEDGE style.

e.g:
SetWindowLong rtb.hwnd, GWL_EXSTYLE GetWindowLong(rtb.hwnd, GWL_EXSTYLE) Xor WS_EX_CLIENTEDGE

Thanks Jim thats great if I want to switch to other things also.

Megatron you're the BOMB!

If anyone else wants to do this here you go:

Dim style As Long
    
    style = GetWindowLong(RichTextBox1.hwnd, GWL_EXSTYLE) Xor WS_EX_CLIENTEDGE
    
    SetWindowLong RichTextBox1.hwnd, GWL_EXSTYLE, style
    SetWindowPos RichTextBox1.hwnd, Form1.hwnd, 0, 0, 0, 0, SWP_FLAGS
