how to read values from msi database?

Thanks

Thanks,
i looked at that code but
Database dbMsiFile = new Database(strFileMsi, OpenDatabase.ReadOnly);
even in that code it is not a defined type, what is that Database class?

majestic0110, i will examine panayquil's code, then i will synthesize the knowledge and come back.

That MSI Analyzer is pretty cool, but here is a simplified answer I whipped up for ya:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices; // Deploying a .NET component customization
using WindowsInstaller;
using System.IO;
using System.Collections;

namespace MSIDataBaseStuff
{
    public partial class Form1 : Form
    {
        [System.Runtime.InteropServices.ComImport(),
            System.Runtime.InteropServices.Guid
            ("000C1090-0000-0000-C000-000000000046")]
        class Installer { }

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            FileInfo msiFile = new FileInfo("setup1.msi");

            // open MSI database
            WindowsInstaller.Installer inst = (WindowsInstaller.Installer)new Installer();
            Database instDb = inst.OpenDatabase(msiFile.FullName,
                WindowsInstaller.MsiOpenDatabaseMode.msiOpenDatabaseModeReadOnly);

            // query the database
            WindowsInstaller.View view = instDb.OpenView
                ("Select `Property`,`Value` FROM `Property`");
            view.Execute(null);

            //fetch each record...
            Record record = view.Fetch();
            while (record != null)
            {
                int iRow = dataGridView1.Rows.Add();
                dataGridView1.Rows[iRow].Cells[0].Value = record.get_StringData(1);// property
                dataGridView1.Rows[iRow].Cells[1].Value = record.get_StringData(2);// value

                record = view.Fetch();
            }

            // close the database
            view.Close();
        }
    }
}
partial class Form1
    {

havent checked yet but if works, oh man!

i have a question here, you open an .msi by specifying a path to .msi.
i want to read that information without knowing the physical path of that .msi. i will use this from within custom installer class, so in any case .msi will be executed first, i want to read information from the .msi which is being executed at the time of reading. Is that clear?
