visual studio 2005 - How to programmatically change a project's product version?

Question

I have several deployment projects. In order to deploy an application, I need to do several tasks, one of them is to change each deployment project's product version and product code.

I can't find a way to programmatically change them.

Since it's a Deployment project (which finally produces an executable installer), I'm not able to work with MSBuild, instead I'm using the Devenv from the command prompt.

I was searching for the exact same thing today. I found this using google:

static void Main(string[] args) 
{
    string setupFileName = @"<Replace the path to vdproj file>"; 
    StreamReader reader = File.OpenText(setupFileName); 
    string file = string.Empty; 

    try 
    { 
        Regex expression = new Regex(@"(?:""ProductCode"" = 
        ""8.){([dw-]+)}"); 
        Regex expression1 = new Regex(@"(?:""UpgradeCode"" = 
        ""8.){([dw-]+)}"); 
        file = reader.ReadToEnd(); 

        file = expression.Replace(file, ""ProductCode" = "8:{" + 
        Guid.NewGuid().ToString().ToUpper() + "}"); 
        file = expression1.Replace(file, ""UpgradeCode" = "8:{" 
        + Guid.NewGuid().ToString().ToUpper() + "}"); 
    } 
    finally 
    { 
        // Close the file otherwise the compile may not work 
        reader.Close(); 
    } 

    TextWriter tw = new StreamWriter(setupFileName); 
    try 
    { 
        tw.Write(file); 
    } 
    finally 
    { 
        // close the stream 
        tw.Close(); 
    } 
 }
