You should use really use WM_APP as your base message number instead of WM_USER. Microsoft makes use of WM_USER + n for many internal messages so it can cause operational issues if there is a conflict.

Yes, Registered Windows messages are better. But:
1. You don't have to send these messages between processes. So there are no problems with Microsoft internal messages.
2. Many customers use current constant messages.

The program doesn't have "FadeIn" feature. Why you need this?
The Delphi code for "FadeOut" on top.

Still getting the same error, I am programing in vb6 from a touchscreen running XP and I am using the manufacturer API, do I need to insure that I activate any other references from there list or can I use the hex value from the vb8 example instead of the WM_User.
I am rusty with vb6 so all help is appreciated.
Thanx

Please look at "Visual Basic 2008 (VB.NET) Sample Code"
Const WM_CSKEYBOARD = &H400 + 192
then
Const WM_USER = &H400
