Writing Data to MSI Database


I need to be able to update a binary table and i do it like so:

View v = session.Database.OpenView("SELECT `Data` FROM `Binary` WHERE `Name` = '{0}'", binaryKeyName);

            v.Execute();

            var IsReadOnly = session.Database.IsReadOnly;

            Record r = v.Fetch();

            StreamReader reader = new StreamReader(r.GetStream("Data"));
            string text = reader.ReadToEnd();
            text = text.Replace(@"Test12345", "TTTest");

            byte[] byteArray = Encoding.ASCII.GetBytes(text);
            MemoryStream stream = new MemoryStream(byteArray);

Once I have the stream I would like to update database table. How do i do it?

Thanks


Solution

  • The dtf.chm documentation, which comes with WiX, contains the following sample on how to update the binary table:

    Database db = null;
    View view = null;
    Record rec = null;
    try
    {
        db = new Database("product.msi", DatabaseOpenMode.Direct);
        view = db.OpenView("UPDATE `Binary` SET `Data` = ? WHERE `Name` = '{0}'", binName))
        rec = new Record(1);
        rec.SetStream(1, binFile);
        view.Execute(rec);
        db.Commit();
    }
    finally
    {
        if (rec != null) rec.Close();
        if (view != null) view.Close();
        if (db != null) db.Close();
    }
