  Hi,
  I´m trying to make word automation on document custom properties(for a given 
  property name change the value)
   
  I put this code together:
  Type Prop = Type.GetTypeFromProgID("Word.CustopParoperties");
              System.Object obj = Activator.CreateInstance(Prop);
              
              Microsoft.Office.Interop.Word.CustomProperties CustomProp = obj 
  as Microsoft.Office.Interop.Word.CustomProperties;
              foreach (Microsoft.Office.Interop.Word.CustomProperty property 
  in CustomProp)
              {   if (property.Name == valfind) property.Value = valreplace;   }
   
  and I get this error
   
  Exception Details: System.ArgumentNullException: Value cannot be null.
  Parameter name: type
   
  Source Error: 
   
   
  Line 53:             
  Line 54:             Type Prop = 
  Type.GetTypeFromProgID("Word.CustopParoperties");
  Line 55:             System.Object obj = Activator.CreateInstance(Prop);
  Line 56:             
  Line 57:             Microsoft.Office.Interop.Word.CustomProperties 
  CustomProp = obj as Microsoft.Office.Interop.Word.CustomProperties;
   
   
  As I understand I dont have the ProgID right
  any ideas what should be there
  I´m quite new to this and running out of hope
   
  Thanks
