Dialog on OnSaveDocument

[Anonymous]

I try to open a Form that i create in the OnSaveDocument Event. I tested the Event with some MessageBox, they show up succesfully.

The Problem, My Form does not show on Screen.

        Private Sub m_appEvents_OnSaveDocument(ByVal DocumentObject As Inventor.Document, ByVal BeforeOrAfter As Inventor.EventTimingEnum, ByVal Context As Inventor.NameValueMap, ByRef HandlingCode As Inventor.HandlingCodeEnum) _
                                  Handles m_appEvents.OnSaveDocument
            If BeforeOrAfter = EventTimingEnum.kBefore Then
                If DocumentObject.DocumentType = DocumentTypeEnum.kAssemblyDocumentObject Or DocumentObject.DocumentType = DocumentTypeEnum.kPartDocumentObject Then

                    CheckCustomiProperty(DocumentObject, "Name englisch", "")
                    CheckCustomiProperty(DocumentObject, "BENKEY", "")

                    Dim oUDProps As PropertySet
                    oUDProps = DocumentObject.PropertySets.Item(4)

                    Dim oProps As PropertySet
                    oProps = DocumentObject.PropertySets.Item(3)

                    If oUDProps.Item("Name englisch").Value = ""

                        MsgBox(oUDProps.Item("Name englisch").Value)
                        MsgBox(oUDProps.Item("BENKEY").Value)
                        MsgBox(oProps.Item(2).Value)

                        MyForm.Show()
                        MyForm.TopMost = True

                    End If

                End If
            End If
        End Sub

The Important Part is:

'WORKS

                        MsgBox(oUDProps.Item("Name englisch").Value)
                        MsgBox(oUDProps.Item("BENKEY").Value)
                        MsgBox(oProps.Item(2).Value)

'DONT WORK
                        MyForm.Show()
                        MyForm.TopMost = True

 Thank you for your help, is it possible to show the Dialog ?

I think you need to make Inventor the parent for your form.
Will you please look into this discussion:

 Here is the source text of WindowWrapper class provided by Josh_Petitt
