>I have purchased the dbi-tech ctGrid Control and it's great....or I thought. I develop on a windows xp workstation and it all works perfect. I tried my new forms on a Windows 2000 workstation, and I ran into an issues. The grid control allows the users to type into a cell, or use a drop-down, checkbox, integer, etc. The problem is when the user is allowed to type into the control. It starts repeating the keystrokes. So I type the letter N, my cell fill with NNNNNNNNNNNNNNNN. But it only happens on windows 2000. I sent dbi a support request and they sent back:

According to that text, you should highlight the WM_CHAR message section and resend it to them. They should be able to resolve it. The easiest way they could is to subclass the edit control, and filter the WM_CHAR messages with a 1 count for the character entries.

Good luck.
