The sample application below demonstrates how to use MsiRecordSetString, MsiOpenDatabase, MsiCreateRecord, MsiCloseHandle, MsiDatabaseOpenView, MsiViewExecute, MsiDatabaseCommit, and MsiViewClose in C# to modify a property value in an MSI database. To run it, simply create a new Windows Console application and replace the code that Visual Studio gives you with the code below. You may have to modify the namespace name. The sample as-is requires a valid MSI database named SETUP.msi, with a property named PROPERTY1 in the Property table, to be located in C:\. You can of course change the path to your MSI database in the calls to ChangeMSIProperty() in Main() and use any existing property you wish.
