Hi, Please check whether ur object is created properly before u call the domodal(). If it is fine, keep the break point in the dialog class's "oninitdialog" function and move forward step by step. I guess the issue would be in any of the controls u have used. Thanks, Arun P.

Knowing where files are certainly makes programs work better :)

You can't force it. Your external process just hasn't stopped yet for some reason. Does your external process wait for the user to "Press any key to exit"?? I sure hope not! A guide to posting questions on CodeProject[^] Dave Kreskowiak

Luc, Thanks for give me the good suggestion.

ah yes! i should've remembered the module definition file.. glad you fixed your bug and shared the solution! :)

Thanks for reminding me, I do get application crash since I didn't use AFX_MANAGE_STATE(AfxGetStaticModuleState()) at first.

Thanks! SelectedIndexChanged event works if the tabpage is not the first one. If the tabpage is the first page (index = 0), the message still cannot be shown.

Luc, Working great, Thank you very much.

That just works fine. Just check the width of your rowheader, if it is less then 30, numbers will not be shown. Make it 50 or so. I've checked this code which uses same code, and works fine. http://www.vb-helper.com/howto\_net\_datagridview\_row\_headers.html

Eddy, Thank you very much, that what I did right now.

Please, ask your question in the VB forum. This forum is for C++. Cédric Moonen Software developer Charting control [v3.0] OpenGL game tutorial in C++

That is correct; if you don't like it, use something else. :) Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles] Nil Volentibus Arduum Please use <PRE> tags for code snippets, they preserve indentation, and improve readability.

User will choose columns from these tables. so we need to list all columns in each table.

Yes, when focus only leave the control when I click other control, do you know how can I let focus leave control when I click other place instead of control on the form? Thanks!

Solve it. The MouseMove event must be set on the parent control. and when get the control from mousemove, should use following syntex: Private Sub GroupBox1_MouseMove() Dim parent As Control parent = sender Dim ctrl As Control ctrl = parent.GetChildAtPoint(e.Location) ......... end sub Thanks!

Hi, I try to use something else to display message that looks like tooltip. I create a label with some message to indicate why its attached control (not real attach) is disabled, set visible = false, I capture the mouse move event, when mouse move to the attached control and also it's disabled, the label with message will be visible, when the mouse move out of the control, the message will be hidden. When I create the control (like textBox) directly in form, and capture Form_MouseMove() event, it works fine. But if I create a TabControl in the form and then a groupbox on the tabpage, then put the textBox control in the groupbox, now I cannot get the control when mouse move by : ctrl = Me.GetChildAtPoint(e.Location) Then ctrl is always Form, or tabControl. Why??

Thanks!

Thanks, David, it's very useful.
