What do you mean by “to others using qt”? You mean you want to implement email sending in Qt? Or contact people who use Qt? If the latter, then you have already found the solution – post a post on this forum ;) But I am almost certain you have mean something else.

I want to Developing email Application in qt.If you have any idea , please share with me.

Thanks for your previous reply.

Hm, never did anything in that direction. You can definitely take a look at QNAM [qt-project.org], which is the new official class for making any network communication. Or, look for some email-only C++ libs and plug them into your Qt GUI.

Ok thanks and another thing How can i get system serial number using qt? or c++ codings?
If you know ,please send me that function().

I will try this and send to back the result
