VB.Net - Windows Forms FolderBrowserDialog Not Opening

[jmarkus]

I'm trying to present the user with a folder dialog to pick a destination directory when they click a button.

I can't get the sub that handles this to show the dialog.

I've stripped down my sub to just the following bare bones code and it still hangs and doesn't show the dialog. How can I debug this?

Private Sub Button13_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button13.Click
[indent]Dim folderBrowserDialog1 As New FolderBrowserDialog
folderBrowserDialog1.ShowDialog()
[/indent]
End Sub

Thanks,
Jeff

This works for me - Visual Studio 2015:

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim folderBrowserDialog1 As New FolderBrowserDialog

        folderBrowserDialog1.ShowDialog()
[green]
        'If FolderBrowserDialog1.ShowDialog() = DialogResult.OK Then
        '    MsgBox(folderBrowserDialog1.SelectedPath)
        'End If[/green]
    End Sub

Try it with a brand new Project in VS just to test it.

Have fun.

It works for me in a new project, but this is in some existing VB code which I am adding to.

Any idea what would cause it to trip up?

Since the FolderBrowserDialog class in System.Windows.Forms has such an awful user interface; maybe someone wrote their own version within the project you are working with and that custom version isn't working just right.

Try changing

Dim folderBrowserDialog1 As New FolderBrowserDialog
' to
Dim folderBrowserDialog1 As New System.Windows.Forms.FolderBrowserDialog

and see if that makes any difference. If it does then you probably have a renegade version of FolderBrowserDialog somewhere in your project.

Nope, no other FolderBrowserDialog exists in the code.

As a "let's see what happens" I put an OpenFileDialog in place of the FolderBrowserDialog, and that worked. Unfortunately that doesn't let me return just a folder.

Sigh.

I just wanted to circle back and let y'all know that I implemented code based on:

http://glassocean.net/how-to-create-a-treeview-file-browser-component-in-vb-net/

in order to create my own folder dialog window that works when FolderBrowserDialog didn't.
