Close Port

Hi all ,

   I am using VB 6 in W2K OS .

   I have problem in my DDE program .
   Let me explain in detail :

The DDE program will call the The Reader program which will open com port in the computer. Everything are OK except that when i close the DDE program , it did not close the port in the The Reader program, eventhough i have the ClosePort method in the Unload method in the Reader program.

Anyone have any idea or suggestion how to call child exe Form Unload() method in the DDE exe program ? How maybe there are another ways ?

Thanks
