I wrote the code according to the sample given in online MSDN doc. So, you have to call MsiGetProperty() method twice. In 1st call, you get the length of the actual value, passed as a 4th parameter of MsiGetProperty() and return value comes as ERROR_MORE_DATA which is correct according to doc. In 2nd call, you have to pass this length as 4th parameter and for 3rd parameter, construct a string array with the size as above length +1. This call returns ERROR_SUCCESS, which is also according to the doc.
So, I am wondering whether I am using the correct string as a 2nd parameter to MsiGetProperty() or not. Can you tell me if there is any problem in this call as I have mentioned in my previous email?

It just wasn't clear from your first post. What's the return value for MsiGetProperty?
