I can't post in the Code Library

[Merrion]

which is probably a good thing as I'm not very experienced in this .Net stuff yet

 

Anyway - the API Exception class is wrong...the API declaration for FormatMessage should be...

 

#Region "API Declarations"
   <DllImport("kernel32.dll", EntryPoint:="FormatMessageA", _
CharSet:=CharSet.Ansi, _
ExactSpelling:=True, _
CallingConvention:=CallingConvention.StdCall)> _
Public Shared Function FormatMessage(ByVal dwFlags As Format_Message_Flags, ByVal lpSource As Int32, ByVal dwMessageId As Int32, ByVal dwLanguageId As Int32, ByVal lpBuffer As StringBuilder, ByVal nSize As Int32, ByVal Arguments As Int32) As Int32

   End Function

#End Region

Fixed.
