I have used the D3 ActiveXForm to create an application, and I also created an ActiveX Library but unable to compile the project. There was a dialog requesting for the host application. Since this project has not been compiled, there is no host application. I am wondering if I didn't set the library correctly or what I am I doing wrong? I was able to compile the project successfully using the ordinary form. I'll appreciate any help and will give more points if need be. Many thanks.
