How to disable buttons on the toolbar!

How to disable buttons on the toolbar!

I have a toolbar on the main window (MDI form) and there is a button on this toolbar. When user clicks the button, a child window will be shown and the button will be disabled.
I did this part. But when that child window closed, the button on the toolbar must be enabled. I tried to enable it in the "Close Event" of the child window but I'm getting an error message like "Unknown identifier ?Button14".
How can I access a button on the toolbar from a child window?

RE: How to disable buttons on the toolbar!

Try placing the code on an embed point from the button on the main menu.  You place it there after the code to pull up the child, then when it returns from the child it will execute this code.

RE: How to disable buttons on the toolbar!

Well, you must to try SETTARGET.

something like

0{PROP:STATUSTEXT,1} = 'Change the status text'

As you know, the FEQ number, is assigned at every control into the window, where 0 always is the windows itself, every control after will be a number (FEQ).

vrg: A Window with an OK and an CANCEL button:
Windows will be 0
IF "TAB" order is OK then CANCEL button:
OK button will be 1
CANCEL button will be 2

so you can change the text to button CANCEL this way:

and change to flat the OK button:

finally change the icon to the window:

So, you can disable control from every window, by just knowing the thread number of the window, and the FEQ of the control.
You can put something like this on your tool's bar button to know it's FEQ


ALWAYS on MDI the Main Windows has the Thread No. 1

You code should be like:


Saludos, CabrĂ³n!.
