No. First of all, consider that the Windows API has no idea what the “VCL” is. It doesn’t know “TButton” or “TStringGrid,” and it certainly doesn’t know “TImage” or “TLabel,” which don’t even have window handles.
You could use
EnumChildWindowsto get handles to the windowed controls. You could look at their class names to determine that they came from “TButton” or “TStringGrid,” but even then, you would not have access to any object-related facilities. You wouldn’t have an object reference, and so you could not read any properties or call any methods.TestComplete, from Automated QA, offers access to a program’s forms and classes from an external program, which sounds like what you might be trying to do. It works by having a unit that you include in the Delphi program, and that unit essentially provides a back door for the TestComplete program to use to query the program’s internals. That requires cooperation from the application developer; you can’t sic TestComplete on an arbitrary program.
