The following example retrieves a type by passing a ProgID, specifying whether to throw an exception if the ProgID is invalid.

/*from   w  w w  . j  a va2 s.  co  m*/
using System;
class MainApp 
{
    public static void Main()
    {
        try
        {
            string myString1 ="DIRECT.ddPalette.3"; 
            string myString2 ="MyProgID"; 
            Type myType1 =Type.GetTypeFromProgID(myString1,true);
            Console.WriteLine(myType1.GUID);
            Type myType2 =Type.GetTypeFromProgID(myString2,true);
        }
        catch(Exception e)
        {
            Console.WriteLine("An exception occurred.");
            Console.WriteLine("Source: {0}", e.Source);
