MsiGetProperty returns an empty string

[ChrisG2]

I am busy upgrading from IS8 to IS2009. My scripts are not working correcly anymore. I discover that the MsiGetProperty doesnt return a value/string.


nvSize=255;
MsiGetProperty(hMSI , "DB_ORACLE_CREATIONFILES", szReturnValue, nvSize);
MessageBox (szReturnValue, INFORMATION);

Who knows the answer?

Where in your sequences or events are you calling MsiGetProperty? If it's an action or event scheduled for "deferred execution", you'll need to go through the "CustomActionData" property, about which see these forums and the online help.

The property is in CAPS and should be public. In IS8 this property returns the correct value. In IS2009 it returns an empty string.

Please see, for example, the help topic "Upgrading InstallShield 11.5 or Earlier Basic MSI Projects that Have InstallScript Custom Actions"; it explains how/why CustomActionData is used in this case...
