Problem with SOURCEDIR when Upgrading Installshield project to IS 2008.

[thaka01]

Hello Everyone!
I have tried to upgrade an InstallShield project created on IS 11.5 to install Shield 2008. I have some install shield custom actions.

When i run this part of script on the first custom action i get the real values
SprintfBox (INFORMATION, "New Source Folder","New Source:%s",SRCDIR);
SprintfBox (INFORMATION, "New Source Folder","New Source:%s",SUPPORTDIR);
SprintfBox (INFORMATION, "New Source Folder","New Source:%s",SETUPEXEDIR);
SprintfBox (INFORMATION, "New Source Folder","New Source:%s",SUPPORTDIR);

But when i run the above script on another custom action the value is blank.

I need to have the path of the source.

Perhaps try calling MsiGetProperty to get the value of, say, SETUPEXEDIR?

[thaka01]

The script i use to get the path is:

MsiGetProperty(ISMSI_HANDLE, "SourceDir", szSourceDir, nvBufferSize);
MessageBox ("SourceDir is:=" + SourceDir, INFORMATION);

MsiGetProperty(ISMSI_HANDLE, "SETUPEXEDIR", szSETUPEXEDIR, nvBufferSize);
MessageBox ("SETUPEXEDIR is:=" + szSETUPEXEDIR, INFORMATION);

The output is the same.
If I use this script on the first custom action I get the right path. Otherwise the values of szSourceDir and szSETUPEXEDIR are blank.

When/where in the sequences are you calling this code? As a sanity check, are you setting nvBufferSize to a large value before each call to MsiGetProperty?

Everything work fine on IS 11.5. But after the upgrade to IS 2008 those part of code do not work same as IS 11.5.
I think is part of the way how IS 2008 works with global variables, and how IS 2008 works with many custom action.

Correct, the InstallScript-in-MSI architecture changed in InstallShield 12; please see the sticky posts at the top of this forum for links to further details.
