Get Folder

[Doug Bell]

Hi,
Is there a way to use the OpenFileDialog to retrieve a directory?

I need to allow the user to set a directory and it may not have any files in
it.

Hi Doug,

if the directory is empty, no.

I need to allow the user to set a directory and it may not have any files
in
it.

Another possibility is to use the FolderBrowserDialog and to check whether
the selected directory contains files or not:

If FolderBrowserDialog1.ShowDialog = DialogResult.OK Then
Dim di As DirectoryInfo = New DirectoryInfo( _
FolderBrowserDialog1.SelectedPath)
If di.GetFiles.Length > 0 Then
MessageBox.Show("...")
End If
End If

Cheers

..NET 1.1:

'FolderBrowserDialog' Class ('System.Windows.Forms.FolderBrowserDialog')
<URL:http://msdn.microsoft.com/library/e...WindowsFormsFolderBrowserDialogClassTopic.asp>

Note that there is a bug in the .NET Framework 1.1 that causes a really bad
error when using a path longer than about 128 characters. This occurs on
Unicode systems only. Use the p/invoke solutions listed below instead.

..NET 1.0:

Folder Browser component for .NET

The bug you mention, is that this one?
http://support.microsoft.com/?kbid=830920

If so, looks like it will get fixed in .NET 1.1 SP 1 (due in Sep)

Yes, that's the bug I was talking about. I'll update my FAQ. Thanks
for making me aware of that.

Thanks,
The Class Module FolderBrowserDialog works fine.
