I am using smtpmail.prg to create and send emails with the attachments. The function works fine on my computer but on clients computer it comes with the following error : Class defination MSWINSOCK.WINSOCK is not found. I have read and followed Sergey's and Naomi's suggestions but I can not get rid of this error. Probably I am not doing thing the right way. This is what I am trying :

Create a class called Oletest, based on "Ole control" and save in "Oletest1.vcx". Then in the insert box, I have selected "Insert control" and selected "Microsoft Winsock control 6.0" and saved the file and added the new vcx in the library list. I don't know if I am on the right track here.

The next step is the one I need help with, how to use this class or a correct class and get rid of the above error and continue sending the emails from clients computers. Anyone out there can help me ??? TIA
