I try to invoke funcitons of AcitveX control in a DLL. However, I found out that the control cannot be initialized normally (m_pCtrlSite=NULL). Therefore, I got "Assertion Failure" (winocc.cpp line 345) on calling the ActiveX function. Also, I don't have any dialog to show. Can I do it if I do not any dialog? What is normal procedure to initialize the control?
Since I am new in VC++, I will be happy if you can tell a bit more on the detail.
