As I said, you don't need this trick (WinAPI), use standard MQL4 and it will become easier to make it work with MT5

Could you please provide a hint so I can explore and learn more about it?  

Are you referring to the `ObjectCreate()` function?

What I want seems achievable with that function and is much simpler. However, the WinAPI trick feels a bit more user-friendly.  

Thanks again! I think I'll go with the `ObjectCreate()` approach unless there's a better option.
