For my program I use the following code:

Dim dr As DialogResult
Dim ofd As New OpenFileDialog

ofd.DefaultExt = "*.*"
ofd.Filter = "All files|*.*"
ofd.FilterIndex = 0

ofd.Multiselect = False
ofd.ReadOnlyChecked = True
ofd.Title = "Selecteer de file"
dr = ofd.ShowDialog()

If dr = Windows.Forms.DialogResult.Cancel Then Exit Sub

Dim fileName As String = ofd.FileName

At my computer this works fine and no errors.
At a users computer I get the following error:

************** Exception Text **************
System.MissingMethodException: Method not found: 'System.String
System.Windows.Forms.OpenFileDialog.get_SafeFileName()'.

This user is like me using Vista.
My program is set to use only .NET 2.0

I do not user SafeFileName, so why this error?
How can I make this error go away?

Hi Eric,
In the snippet you've posted, it seems there's no usage of
SafeFileName property which is part of .NET 2.0 SP1 according to the
web. I suggest you to search entire code file again(can be done by
"Quick Find") for "SafeFileName" against any risk of usage of that
property that you may have missed to see.

If you have used SafeFileName and getting that exception, try to
switch it to "FileName" property instead.

Hope this helps,

This piece of code is the first in the button-click routine and the exception
comes when this button is clicked.
There is no other use of SafeFileName in the rest of the code.

Is installing SP1 an option for the machine that fails?
