uninstallation

Question

Hi
Friends in a winform I have a button called uninstall .Upon clicking on this button I want to uninstall certain software say for example winamp and also I want to know how to end a process say spool.exe that is running. We can do this by clicking remove in the add/remove programs of control panel and clicking the end process button in the task manager but I want to do it in my program say form1.cs button click event?
plz help
thanks

well my friend this are 2 very good questions in order to kill a process here is a code snippet: //Namespaces needed using System.Diagnostics; public bool FindAndKillProcess(string name) { //here we're going to get a list of all running processes on //the computer foreach (Process clsProcess in Process.GetProcesses()) { //now we're going to see if any of the running processes //match the currently running processes by using the StartsWith Method //this prevents us from incluing the .EXE for the process we're looking for. //. Be sure to not //add the .exe to the name you provide i.e: NOTEPAD //not NOTEPAD.EXE or false is always returned even if //notepad is running if (clsProcess.ProcessName.StartsWith(name)) { //since we found the proccess we now need to use the //Kill Method to kill the process. Remember if you have //the process running more than once say IE open 4 //times the loop thr way it is now will close all 4 //if you want it to just close the first one it finds //then add a return; after the Kill clsProcess.Kill(); //process killed return true return true; } } //process not found return false return false; } in order to uninstall a program you can either do that by msi like this : private void uninstallSoftware() { Process p = new Process(); p.StartInfo.FileName =  msiexec.exe ; p.StartInfo.Arguments =  /x \C:\Application.msi/qn ; p.Start(); } or by registry information like this for Adobe Reader 7.0.8 : Microsoft.Win32.RegistryKey Fregistry = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(SOFTWARE) .OpenSubKey(Microsoft).OpenSubKey(Windows).OpenSubKey(CurrentVersion) .OpenSubKey(Installer).OpenSubKey(UserData) .OpenSubKey(S-1-5-18).OpenSubKey(Products); string []Names = Fregistry.GetSubKeyNames() ; string uninstall = ; string ApplicationName = Adobe Reader 7.0.8; for (int i = 0; i { Microsoft.Win32.RegistryKey FTemp = Fregistry.OpenSubKey(Names[i]).OpenSubKey(InstallProperties); if (FTemp.GetValue(DisplayName).ToString() == ApplicationName) { object obj = FTemp.GetValue(UninstallString); if (obj == null) uninstall = ; else uninstall = obj.ToString(); i = Names.Length; } } System.Console.WriteLine(uninstall); System.Diagnostics.Process FProcess = new System.Diagnostics.Process(); string temp = /x{ + uninstall.Split(/.ToCharArray())[1].Split(I{.ToCharArray())[2]; //replacing with /x with /i would cause another popup of the application uninstall FProcess.StartInfo.FileName = uninstall.Split(/.ToCharArray())[0]; FProcess.StartInfo.Arguments = temp; FProcess.StartInfo.UseShellExecute = false; FProcess.Start(); System.Console.Read();
