I use Microsoft Internet Transfer Control (iNet) in my application to communicate with other side via https. The code is like this.

oInet.execute(url, "POST", MyRequest)
... wait till finished
msgHead = oInet.getHeader()
......

It works fine if I run my application directly. But if I call my application from another application via Windows API call, I cannot get any response (doesn't have anything in the message head, and no state change in INet) after execute. Is there any special I need to do for MS Internet Transfer Control ActiveX when the application is called by Windows API?
