How to get the upgrade code using the MsiGetProductInfo and MsiOpenDatabase?

I have read a few posts on StackOverflow itself about getting the UpgradeCode using 2 queries. First, use MsiGetProductInfo to get the database path (how?!) to open the database which will contain the UpgradeCode. Please provide the API call to fetch the database path! Urgent.

Call MsiEnumProducts to find the package code if you only know the name, then call MsiGetProductInfo with the product code to get INSTALLPROPERTY_LOCALPACKAGE property (i.e. the "database"/msi file), open the database, find UpgradeCode in the property table, done. That answers your question - but I'm not sure why you would need this in such a manner.
