Close windows application

Question

Hi guys, is it possible to close a running application with another application?

I have implemented APP1.exe and APP1_UNIN.exe, I would that APP1_UNIN.exe kill running APP1.exe and uninstall it. Is it possible?

Answer 1

Use System.Diagnostics.Process class:

http://msdn.microsoft.com/en-us/library/system.diagnostics.process.closemainwindow(v=VS.71).aspx

There's also a Kill method.

Answer 2

At least to kill the running process you can do like this:

Process[] processes = Process.GetProcesses();
foreach (Process process in processes) {
  if (process.ProcessName == "APP1.exe") {
    try {
      process.Kill();
      break;
      } catch (Exception) { 
        //handle any exception here
      }
    }
  }
}

Regarding uninstalling it, I'm not sure.

Answer 3

For closing, you can do it by killing its process. System.Diagnostics.Process

Process []pArray = Process.GetProcesses();

foreach(Process prc in pArray) {
    string s = prc.ProcessName;
    if (s.CompareTo("APP1") ==0) {
        prc.Kill();
    }
}

Answer 4

Yes using System.Diagnostics

You can get the process and Kill the Process.

Answer 5

To uninstall an application, you can start a new process and invoke msiexec.exe, and on the command line you can specify what to uninstall:

ProcessStartInfo psi;
//take your choice of which you want to use:
psi = new ProcessStartInfo("msiexec.exe", string.Format("/x {0}", "path of my msi"));
psi = new ProcessStartInfo("msiexec.exe", string.Format("/x /n {{{0}}}", "my product code"));
Process p = new Process();
p.StartInfo = psi;
p.Start();
