C Sharp - Question - Multiple Commands in one

[Valvaris]

Hi @ all,

im in a Projekt to help my co Workers with a little app to save time in uninstallig a special app - My Goal is to write this tool in Framework 2.0 (Windows Forms Projekt) and later after 6-8Months to Framework 3.5.

OK now to my question - I know it sounds N00b but need help on how to setoff multiple commands to scan registry on a button.

My Code Looks like so:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows;
using System.Windows.Forms;
using System.Security.Principal;
using System.Diagnostics;
using Microsoft.Win32;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button5_Click(object sender, EventArgs e)
        {
            WindowsIdentity wi = WindowsIdentity.GetCurrent();
            WindowsPrincipal wp = new WindowsPrincipal(wi);

            if (wp.IsInRole(WindowsBuiltInRole.Administrator))


                // Ok, user is administrator
                MessageBox.Show("OK");

            else

                // Non privileged user, not ok to continue...

                MessageBox.Show("Nooooooo");
        }

        private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
            string mailtoString = @"mailto:xxx@xxx.xx";

            Process.Start(mailtoString); 
        }

        private void button3_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            string MyKeyName = "HKEY_LOCAL_MACHINE\\Software\\Test\\Product\\PAA003XX\\Versions\\1.0";
            string MyKeyName1 = "HKEY_LOCAL_MACHINE\\Software\\Test\\Packages\\PAA003YY\\Versions\\1.0";
            string MyValueName = "CompVersion";
            string MyValueName1 = "CompVersion";
            string MyValue = "####";
            string MyValue1 = "####";
            object MyObject = null;
            object MyObject1 = null;


            //Registry.GetValue returns an object:

            MyObject1 = Registry.GetValue(MyKeyName1, MyValueName1, null);
            if (MyValue1 != "####")
            {
                //Get the string value of the object returned:
                MyValue1 = MyObject1.ToString();

                MessageBox.Show("Product Version = " + MyValue1);
            }

            else
            {
                MessageBox.Show("Product X not found");
            }

            MyObject = Registry.GetValue(MyKeyName, MyValueName, null);

            if (MyValue != "####")
            {
                //Get the string value of the object returned:
                MyValue = MyObject.ToString();

                MessageBox.Show("Product Version = " + MyValue);
            }

            else
            {
                MessageBox.Show("Product Y not found");
            }




        }
    }
}

Main Code of problem is the Event from private void button2_Click(object sender, EventArgs e) - Downwards the rest is kinda ok.

how do i get this to work im very new to C Sharp still need to learn allot.

Many MAny thx in advance Val.

--------------------- UPDATE -------------------------

----------------------SOLVED------------------

Yes I did it --> So this is the Code I use now and it works!

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows;
using System.Windows.Forms;
using System.Security.Principal;
using System.Diagnostics;
using Microsoft.Win32;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button5_Click(object sender, EventArgs e)
        {
            WindowsIdentity wi = WindowsIdentity.GetCurrent();
            WindowsPrincipal wp = new WindowsPrincipal(wi);

            if (wp.IsInRole(WindowsBuiltInRole.Administrator))


                // Ok, user is power user or administrator
                MessageBox.Show("OK");

            else

                // Non privileged user, not ok to continue...

                MessageBox.Show("Nooooooo");
        }

        private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
            string mailtoString = @"mailto:xxxx@xxxxx.xx";

            Process.Start(mailtoString); 
        }

        private void button3_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            string MyKeyName = "HKEY_LOCAL_MACHINE\\Software\\XXXXX\\Packages\\PYY003XX\\Versions\\1.0";
            string MyKeyName1 = "HKEY_LOCAL_MACHINE\\Software\\YYYYY\\Packages\\PYY003YY\\Versions\\1.0";
            string MyValueName = "CompVersion";
            string MyValueName1 = "CompVersion";
            string MyValue = "";
            string MyValue1 = "";
            object MyObject = null;
            object MyObject1 = null;


            //Registry.GetValue returns an object:

            MyObject = Registry.GetValue(MyKeyName, MyValueName, null);
            if (MyObject != null)
            {
                //Get the string value of the object returned:
                MyValue = MyObject.ToString();

                MessageBox.Show("Product X Version = " + MyValue);
            }

            else
            {
                MessageBox.Show("Product X not found!");
                MyObject1 = Registry.GetValue(MyKeyName1, MyValueName1, null);

                if (MyObject1 != null)
                {
                    //Get the string value of the object returned:
                    MyValue1 = MyObject1.ToString();

                    MessageBox.Show("Product Y Version = " + MyValue1);
                }

                else
                {
                    MessageBox.Show("Product Y not found!");
                }
            }






        }
    }
}

So what happened ive mixed the MyObject with the MyValue and recieved a String Error if nothing was found and if something got found nothing will happen becouse it got stuck. Now it searches for Product X and if thatone got found its done - But if Product X wasnt found it will search for Product Y and then its done ---- IF Found dialouge with Version of Product X/or/Y or a Message!!!

So many many Thanks @ all - Bestregards HAppy Holidays @ ll and BEst regards Val.
