The following code works when I debug and when I install the software
and run the .exe, but if I try to open the form in the designer (which
causes this code to run), I get an error:

Private Sub LoadTestSettings()
   Dim rootPath As String
   Dim eventHandler As ValidationEventHandler
   rootPath = My.Application.Info.DirectoryPath
   eventHandler = New ValidationEventHandler(AddressOf
XmlValidationEventHandler)
   _xmlDocument = New XmlDocument()
   _xmlDocument.Load(rootPath & "\" & "TestSettings.xml") '-->this is
where the error occurs<--
   _xmlDocument.Schemas.Add("http://tempuri.org/TestXmlSchema.xsd",
rootPath & "\" & "TestXmlSchema.xsd")
   _xmlDocument.Validate(eventHandler)
End Sub

If I try to open the form in the designer, I get this error:

Could not find file 'C:\Documents and Settings\DanThMan\Local Settings
\Application Data\Microsoft\VisualStudio\8.0\ProjectAssemblies
\gyyihrso01\TestSettings.xml'.

I can't figure out what to specify for the filename in
XmlDocument.Load(string fileName). Does
My.Application.Info.DirectoryPath not work if not in debug mode? If
not, what should I do to get the designer to open?

Thanks for your help,
