Can't disable last used button

Der_Andi · January 6, 2010

Hi,

there's a button on my GUI I can't disable.

As this is the last used button, I moved the focus to another control. Still I can't disable it.

Let's call this button the problem-button.

About the button:

The problem-button calls a function, which creates a child GUI, displays it and disables the main GUI.

This child GUI has a button, too. It calls the work-function, which does some work and when finished calls the close-function and then the update-function.

The close-function deletes the child GUI, re-enables the main GUI and moves the focus from the problem-button to another button.

The update function then will refresh some data on the main GUI and depending on that data finally disables the problem-button.

And THAT does not work and makes me really mad!

In a manner of speaking, the update-function is triggered by the problem-button. I came to the conclusion, the program has to exit the whole chain of functions to "free" the button. Only after that it could be disabled. So I hotkey-ed a test function, that just disables the button, when I press F10.

I pressed the problem-button and it did the usual work. When everything was finished and the main GUI seemed to be in normal state again, I pressed F10, but the button still can't be disabled!

GUICtrlSetState($btn, $gui_disable) returns always 0 in this case.

Why? Is there anything else, that keeps blocking the button?

I tried to make an example script with exactly the same 'architecture', but for some reasons this just works fine. :evil:

Regards,

Andreas

Edit:

I'll cut this short. Here's the whole thing.

Just find the line with GUICtrlSetOnEvent($btnErase, "showEraseWarning") and follow the white rabbit.

Der_Andi,

You have this line in your main script:

$btnErase = GUICtrlCreateButton("Speicherkarte löschen", 250, $topAction+30, 210, 25)

and this line in your showEraseWarning function:

$btnErase = GUICtrlCreateButton("Ja, alles löschen", 240, 120, 150, 25)

Does that give you a clue?

M23

You are overwriting the ControlID so that the first button no longer exists as far as AutoIt is concerned!

Der_Andi · January 6, 2010

Does that give you a clue?

YES!!! I need a break. :evil:

Good god! And I just wondered why $btnErase first has the value 29 and later 33!

And now I also know, why the example script worked. I used completely different variable names!

Thanks very much!!
