hi everyone

Thank you

If I understand your question correctly, you want to add an operation to a class, and this operation should have a parameter, which is optional.
You do this by filling in a value in the "Default" field on the Parameters page of the Operations dialog box.

In C++ this generates the declaration shown below, when Param2 has a default value of 117:

void MyFunction(int Param1, int Param2 = 117);

I hope it helps

Sorry, I tried with "Optional" in default field but its gave me error.
Any other solution?
Here is an example what I am after(in VB):

Public Sub Add (lngID as Long, Optional strType as String)
....
....
End Sub

Thank you for your kind help.
