Hi Ark,

I tried the code on link provided, but i crash my VB. It got error on Kernel.dll as:

did you close the App via the Stop button in the VB IDE? When subclassing a window, you have to close it via the "X" button, or some other coded way... Otherwise, the Unload() code never executes, leaving windows unsure of where to send messages etc (I think, lemme know if im wrong)...

Hi JonFish85,

Sorry i'm not quite understand on what is your comment.

> did you close the App via the Stop button in the VB IDE?
So what method should i use to "Close" the window?

But before that my VB crashed before the code is successfully executed.

Any comments? Any useful links/ articles?

Thanks A Lot to ALL. : )

Hi
When using subclassing, you should close program in IDE ONLY with main form [x] button. There won't be a prb when compiled.

Cheers

Hi Ark,

This question has been opened for a long time now (sorry about that), as got some free time to research recently i go back to this question.

As testing the code form the link you provided (VBNet) i still get the error. This time is:

"Invalid use of AddressOf" in HookWindow. I think this is a typical error. How can i figure it out?

Win2k, VB6 development environment.

Thanks a lot.

"Invalid use of AddressOf" - this often occure when you place CallBack function at form/class module.
Function which you use in AddressOf operator MUST BE IN A BAS MODULE ONLY and be Public

Hi Ark,

Although "Invalid use of AddressOf" error had been removed, but the whole running project disappear (corrupted?) from my desktop within seconds. So ..?? What may cause this happen?

Thanks

Seems it's corrupted. This is subclassing behavior - when you subclass window/control, all messages come to your callback function first. But if you have an error inside function, VB try to interrupt process, while messages continue redirecting to missing(interrupting) function. This cause GPF. Check all code. Follow all instructions from VBNet (i.e. place everything they say "bas module" in bas module, "form code" - into form, name all controls same as in their code).

Cheers
