Hi The first step is to create the activex control like in http://www.c-sharpcorner.com/UploadFile/dsandor/ActiveXInNet11102005040748AM/ActiveXInNet.aspx Second step is to use CAxHostWindow that implements the necessary interfaces in order to support the hosting of common ActiveX controls (including windowless) and Microsoft Web Browser control. In case you do not need to host a Web Browser control you can define _ATL_NO_DOCHOSTUIHANDLER in your project and save about 4K in release dll. CAxHostWindow derives from CWindowImpl and this means it needs a window to operate. CAxHostWindow can host only one control at a time and as a result one CAxHostWindow is required for each hosted control.
