How can I programmatically read the properties inside an MSI file?

Question

Is there a way to read the properties inside an MSI file?

For example, given a MSI file named Testpackage.msi, I need to find

productName
PackageCode
version

This I am going to use it with WMI uninstall

string objPath = string.Format("Win32_Product.IdentifyingNumber='{0}', Name='{1}', Version='{2}'", "{AC9C1263-2BA8-4863-BE18-01232375CE42}", "testproduct", "10.0.0.0");

Using Orca is a great option, if this can be achieved programmatically. Then I can use this to generate automatic release notes. And in un-installing program too.

You can use the COM-based API for working with MSI, and do something like

Function GetVersion(ByVal msiName)

    Const msiOpenDatabaseModeReadOnly = 0
    Dim msi, db, view

    Set msi = CreateObject("WindowsInstaller.Installer")
    Set db = msi.OpenDataBase(msiName, msiOpenDatabaseModeReadOnly)
    Set view = db.OpenView("SELECT `Value` FROM `Property` WHERE `Property` = 'ProductVersion'")
    Call view.Execute()

    GetVersion = view.Fetch().StringData(1)

End Function
