How to find the ProductCode of one installed app.msi

[VP]

I developed one app.msi to intall one app. And I need to develop one
bootstraper.exe to retrieve the ProductCode of previously installed app
outside the MSI.

Some one suggested me to use MsiOpenDatabase/MsiViewExecute.

Could you please give me an example how to use it?

Here's some vbscript to show you how to use those objects:

Untested but'll you get the idea:

Set installer = Wscript.CreateObject("WindowsInstaller.Installer")
Set database = installer.OpenDatabase("c:\path\toyour\msifile.msi", 0)
query = "SELECT 'Value' FROM Property WHERE Property='ProductCode'"
Set view = database.OpenView(query)
view.Execute
Set record = view.Fetch
WScript "ProductCode is " & record.StringData(1)
