To implement a process watcher in Delphi, you will need to use the TProcess class, which is part of the Classes unit. This class provides methods and properties that allow you to create, manage, and monitor the execution of external processes.
Here is an example of how you might use the TProcess class to implement a process watcher in Delphi:

uses Classes; var Process: TProcess; begin // Create a new TProcess instance Process := TProcess.Create(nil); // Set the command line parameters for the process Process.CommandLine := ‘”C:\Program Files\MyApplication\MyApplication.exe”‘; // Set the current directory for the process Process.CurrentDirectory := ‘C:\Program Files\MyApplication’; // Set the application’s window state Process.ShowWindow := swHide; // Start the process Process.Execute; // Wait for the process to finish Process.WaitOnExit; // Check the exit code of the process if Process.ExitCode = 0 then WriteLn(‘Process finished successfully.’) else WriteLn(‘Process finished with error code: ‘, Process.ExitCode); // Free the TProcess instance Process.Free; end; |
In this example, we create a new TProcess instance and set the command line parameters and current directory for the process. We then start the process and wait for it to finish, and check the exit code to determine if it completed successfully or not.
