Hallo,

I want to clean up directories on uninstall. These directories are installed by the IS. To this directories are files copied by the installed program.
These Directories are set by
ComponentSetTarget(MEDIA, "<DATADIR>", szDataDir);
Is it possible to get the value on uninstall?

Thanks for any help,

Get what value?  The value of DATADIR/szDataDir?

Most installs manually save off the installed location to the registry for future use.  However, if you've failed to do this, I don't think the uninstall auto. pick this back up, but to find out just add some debug messages or run through it with the debugger and see what you get.

I'm guessing you are a bit of a newbie, so when you do, you'll most likely want to focus on OnMainUIBefore & OnMainUIAfter.

Hope I did understand everything correctly, sure I'm a bit newbie in using installshield:

I need to get the value of that, what in the install process is assigned to <DATADIR>, the target directory of my data in szDataDir.
May be I can get this value (of szDataDir on install) on uninstall like <TARGETDIR>?

I think the easiest way would be to save the installation path in someregistry entry, and try to read it in the OnBegin event handler.

Ok, thank you all for help,
I thought that this will be done by the Installshield "automatically" and I can read it by an scriptfunction like ComponentGet...()

Hi,

Once you have set the varaibles using
ComponentSetTarget(MEDIA, "<DATADIR>", szDataDir);

declare szDataDir as a globbal variable and have the following line in the function OnMaintUIBefore

szDataDir=TextSub.Value("szDataDir")

This might work, usually I have the first line as
ComponentSetTarget(MEDIA, "<szDataDir>", szDataDir); -- both the script-defined variable and my global variable same.

Hope this helps

cool, this works,
I can use

szDataDir = TextSub("DATADIR")

witch extraxts me the path of the directory decared as <DATADIR> in the Script-Defined Folder.

Thank you!

Torsten.
