Re: [WiX-users] How to move progress bar during custom action

2009-03-18 Thread Don Benson 
In order to show progress, you have to know two things: total work to be
done and current amount of work completed. MsiProcessMessage is used to
notify Windows Installer how much work has been completed.
Who knows how much work has been done? If it is the EXE that you cannot
modify, then I don't know how you could use a realistic progress bar.

You could fake the progress bar by creating a custom action that spawns two
background threads. One thread is the EXE that needs to run and the other is
a timer. When the timer updates you could increment the progress bar through
MsiProcessMessage.

To do this trickery, you'd have to estimate how long the EXE should take to
run. If a computer is faster, then your task will finish before the progress
bar is filled up. If the computer is slower, then your progress bar will get
"stuck" at 100% completed.

I have a lengthy executable that runs at the end of an installer. My
ProgessText for the custom action includes the text "This may take several
minutes. Please be patient." The users don't get a progress bar, but their
expectations are set.

Hi Richard,

 Thanks for your suggestion. How do I use it? I can't modify EXE. Where 
I have to write MsiProcessMessage?

Regards,

I think that's only because that example is talking about a deferred
CA which must be in the install transaction.

To change the progress bar, you need to call MsiProcessMessage with
INSTALLMESSAGE_PROGRESS.  See

The Windows Installer documentation seems to indicate that the progress bar
does not work after InstallFinalize. Check out the following, link,
especially step 9.

[WiX-users] How to move progress bar during custom action

2009-03-17 Thread Michael 
Hi,

 I have a custom action after 'InstallFinalize' which runs an EXE. EXE 
will execute for long time. During that period,  progress bar is not 
moving. Progress is being empty. Give me some suggestions about how to 
show progress bar during custom action.

Thanks,

-SMR
