Win32 error codes are translated from their numeric representations into a system message when they are displayed. Use NativeErrorCode to access the numeric representation of the error code associated with this exception. For more information about the error codes, see "Win32 Error Codes" in the Platform SDK documentation at http://msdn.microsoft.com.

The following code example shows how to catch a Win32 exception and interpret its content. The example attempts to start a nonexistent executable, which results in a Win32 exception. Upon catching the exception, the example fetches the respective error message, code, and origin of the exception.
Try Dim myProc As New System.Diagnostics.Process() myProc.StartInfo.FileName = "c:\nonexist.exe" 'Attempting to start a non-existing executable myProc.Start() 'Start the application and assign it to the process component. Catch w As System.ComponentModel.Win32Exception Console.WriteLine(w.Message) Console.WriteLine(w.ErrorCode.ToString()) Console.WriteLine(w.NativeErrorCode.ToString()) Console.WriteLine(w.StackTrace) Console.WriteLine(w.Source) Dim e As New Exception() e = w.GetBaseException() Console.WriteLine(e.Message) End Try
