Invalid Execution Context again

[GeeHaa]

Hi

I am recieving the message invalid execution context when I try to open a drawing. The form that this button is on was opened modeless.

any help would be much appreciated.

 Private Sub BTN_Select_Attribute_Tag_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BTN_Select_Attribute_Tag.Click
        OpenFileDialog1.Filter = "AutoCAD Drawings|*.dwg"
        OpenFileDialog1.Multiselect = False
        Dim dialogRes As DialogResult = OpenFileDialog1.ShowDialog()

        If dialogRes = Forms.DialogResult.OK Then
            Dim dwgName As String = OpenFileDialog1.FileName

            Dim acDoc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(dwgName, True)

I think I figured it out.

If I dispose of Openfiledialog1 it opens the drawing without an error.

Thanks Again.
