IGxDialog hangs when on sub forms

Hi, I have been tackling this error for days. I am in Arg10.0 Windows 7 using Engine. This all worked in 9.3, but now converting I have having some issues with accessing files. The following code works fine in the main form(I use 0 for the parentWindow), but it doesn't work on any sub forms. I have tried adding the IntPtr value, but same error "VSHOST.EXE has stopped working". it just hands trying to navigate to folders.

        Dim pGxDialog As IGxDialog
        Dim pSel As IEnumGxObject = Nothing
        Dim pGxobj As IGxObject = Nothing

        Dim Result(2) As String

        Try

            pGxDialog = New GxDialog
            pGxDialog.AllowMultiSelect = False
            pGxDialog.StartingLocation = "C:\"
            pGxDialog.Title = Title_Display
            pGxDialog.ObjectFilter = New GxFilterShapefiles

            Dim vptr As IntPtr
            vptr = Me.Handle

            'make sure something was selected
            If Not pGxDialog.DoModalOpen(pvtr.ToInt32, pSel) Then
                Exit Function
            End If

thanks

I don't anything about this function and don't program in VB.NET.

That said, it looks like you set up a variable named "vptr" but then pass one named "pvtr" to the function.

Implicit variable declaration is not one of the better features of VB.NET.

Yes, you are totally correct, that was bad on my part. I had been playing with other options in that variable, had tried the 0 again, so that was a typo. The program would've even built properly if that was the case.
I wish it was that easy. I think now there are more issues with converting 9.3 to 10.0 than just changing library references.

thanks,

Apparently, IGXDialog is not available in ArcEngine 10!!!! so if anyone has a work around, besides Window.forms dialog, please let me know.

thanks
