Hi, Does any know a method/tool to peek inside a OCX control to find what DLLs it refers to, the versions of the DLLs, what functions are available. I have a OCX control. When I view it in binary mode, I can find it having a reference to "DirectDrawCreate" which is a part of DirectX. Can I find out from the OCX which version of the DDraw.dll it refers to ? Any help is very much appreciated. Thanks in advance Arun
