[VB][Resolved] name "OpenFileDialog" is not declared

 * Visual Studio 2008 with .Net framework version 3.5

Error code:

Dim result As DialogResult = OpenFileDialog.ShowDialog()

If result = DialogResult.OK Then

  'Do sth

End If

Firstly let imports System.Windows:

Imports System.Windows

and then try another syntax

Dim odf As FileDialog = New OpenFileDialog()

If odf.ShowDialog = DialogResult.OK Then

  'Do sth

End If
