I'm in need of subtatial help with trancexx's FileSelectFolder UDF, if possible from the author herself. That UDF uses COM objects derived from the system-standard file dialog (IFileDialog), which object is then somewhat modified to implement the specific features trancexx wanted. What I want to do is modify that COM object further to add two Radio Button groups to the dialog, and return their values to the caller. Here's a rough example of what I think the modified FileSelectFolder2 code would have to approximate. Note that the string arguments containing all caps are from a C++ example provided by Microsoft. ; _MyModSelectFolder.au3 ;.......script written by trancexx (trancexx at yahoo dot com) ; Donations to help me write more are very welcome.

For example, what data structures are used in these COM object calls, such as the Radio Button List Control ("CONTROL_RADIOBUTTONLIST"), and how do I create and populate them? Am I missing any method calls I need? Etc, etc... I would be endlessly grateful for guidance and coding assistance!

Link and example: FrameGrabber.dll What about my question regarding returning a bitmap handle or bitmap data rather than saving the grabbed frame to disk? Actually I would talk about VScript because I'm curious but Jon doesn't want it but can you show me the code please? You said it is similar to AU3 code. I want to understand how you did it. Thanks.
