VB.NET OpenFileDialog RestoreDirectory for each dialog

Here is a code snippet (VB.NET 2005) that demonstrates how you can implement a separate RestoreDirectory for each of the OpenFileDialog’s you have.

Basically what this does is it allows you to have multiple “Browse” dialogs that each remember their own last directory used.

I have added comments to Button1_Click code only as Button2_Click code is pretty much the same:
[code]Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
‘declare a new instance of OpenFileDialog
Dim diag As New OpenFileDialog

‘set initial directory to be shown to button’s tag value.
‘this is initially blank
diag.InitialDirectory = Button1.Tag

‘sets button’s tag to directory of the file selected
If diag.ShowDialog() = Windows.Forms.DialogResult.OK Then
Button1.Tag = System.IO.Path.GetDirectoryName(diag.FileName)
End If

‘output last directory shown on a label
Label1.Text = Button1.Tag
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim diag As New OpenFileDialog
diag.InitialDirectory = Button2.Tag
If diag.ShowDialog() = Windows.Forms.DialogResult.OK Then
Button2.Tag = System.IO.Path.GetDirectoryName(diag.FileName)
End If
Label2.Text = Button2.Tag
End Sub
End Class[/code]
Now, assuming that you will be putting a button to show the openfilediaglog, and assuming you will have a button (or some kind of control) for each of the openfiledialog, we can utilize the button’s or control’s .Tag property to store the directory last shown.
