We have an active-x control developed using ATL with MFC support. Our active-x control shall be used in something called frame application. The frame application create its own active-x control and embed our active-x control inside it at runtime.
There are 20+ frame applications in the industry. Now the issue is that each frame application is creating its own active-x container on its own size. But we want to notify the frame application about the required control size so that the frame application can resize its active-x control size itself.
Are there any way to do this?
