How to block all callbacks from Toolbar?

[howdy]

I noticed there are many callbacks going in Toolbar such as ToolbarCallback, ParentPanelCallback, HelpPanelCallback. I want to block all those callbacks when I call ProcessSystemEvents(). Does anyone know how to do that? Thanks.

I'm not aware of any explicit command to disable those callbacks.

Since all of those functions are relate to the tollbar being operated, probably the best way to have those functions do nothing is that of hiding the toolbar before entering your critical section of code and enabling it after.

As an alternative, you could modifiy tollbar code to customize it to your desire: not so easy since you'll have to carefully study that code before attempting to modify it.

Thanks. What about my other questions posted yesterday? I need to know how much time is spent in reading data from hardware in my second thread. So I have to use Timer (). But as I mentioned in my yesterday's post, the computer will freeze when I call Timer (). Do you have any good solutions? Thanks.

Are you afraid the computer will freeze of have you verified it has frozen?

I was looking into ToolbarPanelCallback, and the only reference to the timer I found is in SetPollTimer routine, which is called with NORESET as the last parameter: with this option, SetPollTimer is not expected to reset the timer.

This looking into toolbar.c code distributed with CVI 7.1.

Here is what I found in Toolbar.c

errChk (SetPollTimer (toolbar, ENABLE, SLOW_POLL_FOR_HELP, RESET));

You mean I should set RESET as NONRESET to solve my problem?

Thanks.

Which version of CVI are you using?

In my code (version 7.1 as already noted) ToolbarPanelCallback calls SetPollTimer (toolbar, ENABLE, FAST_POLL_FOR_HELP, NORESET); without errchk macro.

This function is always called with NORESET parameter except inside Toolbar_DisplayInternal function, which is called by several update functions inside the instrument (add or discard a button and so on) but NOT from ToolbarPanelCallback.

Sorry, I looked at the wrong place. I am also using CVI7.1. Could you please take a look at the problem I posted yesterday? computer frozen in secondary thread

Thanks.
