Does anyone have a code snippet or advice on easily writing results from an InstallScript custom action to the MSI database?

Specifically, I am attempting to list the SQL Servers available in a listbox in a Basic MSI project. I found a great code snippet here on InstallSite that will list the SQLServers, but I need to be able to write the results back to the listbox table in the MSI database.

I'm a relative novice at InstallScript.

Thanks in advance!

In your InstallShield program directory under Samples\ScriptSamples you'll find a .rul file that includes a function to add entries to a combo box. List boxes work quite similar to combo boxes.

Thank you! I wasn't aware of the code samples that were installed with InstallShield.

I'm having a little problem getting the sample code to run. I can step through the code with no errors, but nothing seems to get written back to the ComboBox table. Shouldn't I be able to see these entries in the ComboBox table of the MSI file being executed in the temp folder?

I'm not a whiz in InstallScript and am likely missing something basic - any ideas?

Thanks GREATLY in advance for your help!

The SDK states that the database cannot be changed at runtime. You can only add, modify, remove temporary rows, columns or tables from a database. I assume this means that any changes you do will be "in memory" only and never be persisted to disk.
