Cuold you help me, please.

Try this code: System.Diagnostic.Process.Start("Path to your chm file")

you need to utilize the after_Update event from the datagrid. The arguments taht are passed include the row and column as ordinals. Then all you have to do is access the information in column 2, manipulate it and change the info in column1. One gotcha to watch out for is that you need to specify which columns you want the event to do work on. You can do this by adding a select...case liek this select e.datagridcolumn (not sure if this is the actual name of the parameter passed) case 2 Make changes to column 1 else do nothing end select

' frm will get each child form and in sample am closing them all ' Dim frm As Object For Each frm In Me.MdiChildren frm.dispose() Next Rizwan Bashir

check this example http://rustemsoft.com/ASPDataGridColumns.htm

Build one function in MDI like this Public Sub SetMenu(Enable as boolean) mnuITem.enabled=enable end sub and call this from mdiChild like me.Parent.SetMenu(True)

Thanks for your help. I used design mode to created oledbadapter, oledbconnection, dataset and combine with a table on SQL Server 2000. When I press Tab key to enter a new row on datagridview but I can't check a old row. Could you help me and give me code demo. Thanks.
