Infinite ProgressBar
Hi,
I'm a nsis newbie, and have created a script to install a program, and uninstall the existing version, before installing a new one. I run the uninstaller in silent mode, so there is no progressbar during uninstallation, but maybe a infinite for a long time job?
Is it possible, to show a infinite progress bar during uninstalling of the old version?
Thank you in advance.
Regards,
Boian
You could play with one of the banner plugins or the LoadingBAR UI for your uninstaller:
http://nsis.sourceforge.net/LoadingBar_UI
http://nsis.sourceforge.net/MSIBanner_plug-in (old)
http://nsis.sourceforge.net/NxSMSILoaderDlg_plug-in (slightly less old)
http://nsis.sourceforge.net/Nxs_plug-in (least old)
Thank you for the response. I have downloaded the plugins, and have already a solution to show a dialog with the progress bar, during execution of the longtime process. Is it possible, to integrate the progressBar into a NSIS installer page?
I have found that the NSdialog, already contains a ProgressBar (NSD_CreateProgressBar), but there is no documentation, how i can use it, and set a value.

well if you want it inside a dialog, then your uninstaller isn't very 'silent' anymore, is it? ;)
The nsDialogs progressbar you'd probably have to alter using windows messaging. See also this thread:
http://forums.winamp.com/showthread.php?postid=2575941
Just in short, you'd want to set up a range...
sendMessage ProgressControl_hwnd ${PBM_SETRANGE32} start end ; e.g. 0 100 for a standard 0%-100% progressbar
And then set the value in your script where appropriate...
sendMessage ProgressControl_hwnd ${PBM_SETPOS} value 0 ; e.g. 33 0 for 33%
ProressControl_hwnd is what you get in the Pop after creating the item with nsDialogs.
PBM_SETRANGE and PBM_SETPOS are defined in WinMessages.nsh (ships with NSIS) - so be sure to include that if you aren't already.
If you want it to be one of those marquee progressbars that just continually loop from left to right, you probably have to set up some manner of style on the thing.. haven't looked into that :)
Edit: This page is informative, though: http://msdn.microsoft.com/en-us/libr...#Marquee_Style
complete example...
!include "WinMessages.nsh"Essentially you would put all of your actions inside the function that is being called, and start/stop/slow-down/speed-up the progressbar from there.

And one more reply.... This is a plugin we actually use for our uninstaller to set the progress of the built-in un.InstFiles page to a correct amount (we use a stored list to delete only installed files, and the built-in progress handling only goes by the number of commands it knows about, so direct control to show a correct progress was needed):
http://nsis.sourceforge.net/RealProgress_plug-in
Note that this plugin does -not- do any marquee style handling - that's not what it's for :D
I have updated the nsDialogs FAQ wiki topic with some more progress bar examples:
