Hi

I've got a part of a program which allows the user to set certain values to the registry. I got two buttons in this panel, one which is "Save & Exit" and one just "Exit". As it takes about 4-5 seconds for it to write it all to the registry an impatient user could after pressing the "Save & Exit" button press the "Exit" button, and the program will then stop writing the wanted values to the registry and exit this part of the program. When pressing "Save & Exit" the button gets grayed out (so you can't click on it again). Is it possible to make the "Exit" button grayed out too when pressing "Save & Exit"?

Another part of the program has another panel with some user objects and the user objects have their own panel. Is it possible to merge to panel of a userobject with the panel of where it is
a user object? Or is there a way to have a panel be "on top" so it cant dissapear behind another panel..

Regards,
Tobias

Tobias,

I'm slightly amazed that your registry writing takes so long - it may be worth examining that as there is probably something amiss there.

In answer to your question though, the answer is 'no' as far as I'm aware: you can set a flag ( so that the 'exit' command is ignored if the other button was pressed first ), hide the panel ( see your second question ) or you can cover the button with something else ( e.g. a dummy button which is greyed out! ).

As to 'merging' panels the answer is 'yes'. Briefly, create a panel for the UserObject; right-click on its icon and select 'restore' then add the sub-panel to the main panel. You can change the UserObject panel view back to an icon in the detail view once you have done that. If you want to look at my mini-tutorial on the subject which covers this aspect go to http://www.preciselyso.co.uk -> VEE Resource Centre tab -> choose Tools and Tips on the right -> look for "Tutorial: Static, Pop-up and Status Panels"

Assuming you have VEE 8.0 or later you easily gray-out the "Exit" OK-button when "Save&Exit" is clicked (and re-enable it again later).
Just declare a name (like ExitButton) for the "Exit" OK-button in Properties. Then use a Formula with: ExitButton.EnableOnPing=FALSE when "Save&Exit" is clicked.
The programmable properties introduced in 8.0 really helps creating good GUIs.

I found the reason why the registry writing takes so long (might be worth adding I've not written this code from the start) and the author of this part has for unknown reason added a delay in the writing. Thanks for the help & tutorial link, I'll read through it in a bit.

Thanks, that did the trick. I had no knownledge about these programmable properties, time to read up on them as they seem pretty handy.

Well I learned something there too. I had seen that property but I guessed what it did and guessed wrongly! What it means is that you can enable/disable the button but it must be pinged ( as normal VEE rules ) before it will operate.

I offer the attached example program: if you let it run then the OK button 'flashes' a couple of times showing it in both enabled and disabled states. If you press the OK button at the end then you cannot re-enable it with by setting the EnableOnPing property to true.

Just for clarity, the object name 'button' can be found by clicking on the OK button, opening the properties and looking for the Declared Name field. Note also that like other variables you can change the scope of that name depending on where you need to access it.
