Cathi...

Thanks for your response.

I'm using C#, so I tried to convert it. However, I must be missing something, because I'm not able to access things like HITTESTINFO. I even tried a code sample from MSDN that was written for .NET, but the code that I paste in doesn't even run. (Even typing 'System.Windows.Forms.DataGrid.HitTestInfo myhit results in an error).
