Navigation:  I Want To... > Automation > Launch the viewer from my application

Use Case

Sample Code

using System.Diagnostics;

using System.IO;

 

internal static class AutomationHelper

{

   public static void StartViewer()

   {

      const string processName = "ClearCanvas.Desktop.Executable";

      const string viewerProcessPath = @"C:\Program Files\ClearCanvas\ClearCanvas Workstation";

 

      Process[] viewerProcesses = Process.GetProcessesByName(processName);

      if (viewerProcesses == null || viewerProcesses.Length == 0)

      {

         string executable = Path.Combine(viewerProcessPath, processName) + ".exe";

 

         ProcessStartInfo startInfo = new ProcessStartInfo(executable, "");

         startInfo.WorkingDirectory = viewerProcessPath;

         Process viewerProcess = Process.Start(startInfo);

         if (viewerProcess == null)

            MessageBox.Show("Failed to start the viewer process.");

      }

   }

}

Remarks

The sample code above checks to see if the viewer process is already running, and if it is, does nothing.  If the process is not running, it will be started.  This method can be executed as many times as you like and only one instance of the viewer will ever be launched.
