I want to make an Active X ctrl that communicates with a device and then sends data to main program. I want to know that Does activex work as seperate process. Does main program waits on ActiveX ctrl or I can do sperate processing simultaneously in my main program. Thanks in advance.

I am using vc++ 6.0. I Have made an unlicensed activex ctrl application from app wizard (MFC activeX ctrl wizard for generating random drawing). When I am testing this Activex by ActiveX control test container, all functions are working fine, but when I am testing it with dialog application, On calling any method of ActiveX it is giving error debug assertion failed. Program ...... File: winocc.cpp; line: 345 I am making an object of this ActiveX ctrl wrapper class in my testing dialog application and then calling method defined in this ActiveX ctrl. My code: CNewSquiggleAcX m_ClNewSquigg; CFileDialog m_ldFile(TRUE); // Show the File open dialog and capture the result if(m_ldFile.DoModal()== IDOK) { CString m_sResults; m_sResults = m_ldFile.GetFileName(); //m_ClNewSquigg.GetSquiggleLength(); m_ClNewSquigg.LoadDrawing(m_sResults); // Error comes in this line calling any activex function } Calling any method of this self created unlicensed ActiveX ctrl is giving error. Please help.
