COM DLL from Delphi in ActiveX Control
-
I want to create ActiveX control which calls COM DLL from Delphi. I have tried this way HINSTANCE m_sampleDLL = LoadLibrary("D:\\SampleDLL.dll"); m_sample_dll = (SAMPLE)GetProcAddress(m_sampleDLL,"TestFunction"); but I am unable to get handle to Testfunction. Is this way is correct? or wether I have to use some other technique to call DLL which COM and written in Delphi. Please Help! THANX...

Pallini's reply still holds. But are you sure SampleDLL.dll has exported function called TestFunction.

what you are expected from sampleDLL.dll. As you are calling from your activex, you might be having some specfication to use it. Do you want the COM object to be created from the dll?
