Sakthiu27-Dec-06 23:40 Sakthiu 27-Dec-06 23:40  you want to use that COM dll .. right ? then you have to register that COM dll in to your system. To do that pres 'Start' button take 'Run' Applicaiotn, inside Run win type 'Regsvr32' then space your COM dll file location. for example., you COM file location is C:\\app.dll then in Run window, type 'regsvr32 c:\\app.dll' press enter now your COM dll is register wit your system. then write COM client program using api's like CoInitialize(NULL),CoCreateInsatnce() and CoUninitialize(); This is the way you have to use COM dll. bye.

AfxOleTerm() - COM Uninitialize. i have really confused. please send any cleared article URL or any sample code... Thankx...

You are mixing simple dll with COM dll. In case of COM dll, there would interface(s) present. Which you need to use. This interface in your case is Igscript . You haven't noticed how interface need to be used from C++ client. Look in to CMfcclientDlg::OnOk. You need to use CoCreateInstance for this purpose. Refer CMfcclientDlg::OnOk. from article and post back, if got any issue. Prasad Notifier using ATL | Operator new[],delete[][^] Re: How can i call COM DLL in vc++ 2005?

Sakthiu20-Dec-06 2:07 Sakthiu 20-Dec-06 2:07  Dear All, I have a MFC application and also i am having a COM interface with that application. Both are running at the same address space. Now that MFC application is up, when I call that COM interface from different program, everything goes correct. well. After the COM fn execution is done, the MFC application goes out of memory (application stoped). What is the reason for this? I need to have MFC application to be in memory still even COM fn is done. To do this, what should i do ? How can i do this ? Kindly help me. Thanks. Re: Question about MFC &COM Application ? Skond23-Dec-06 2:50 Skond 23-Dec-06 2:50  Perhaps an extra IYourInterface::Release() happens caused by returning the interface pointer to the client via GetIDispatch(FALSE). Must be GetIDispatch(TRUE) to increase internal reference count. hallelujah Call DLL in VB.Net rajiv KumarMM18-Dec-06 19:48 rajiv KumarMM 18-Dec-06 19:48  Want to call a dll which is created in vb 6 in vb.net.
