Geçerli etkin uygulama adını edinin

Question

Zamanlayıcı durduğunda aktif olan uygulamanın adını almak istiyorum. 20 sn kaydettikten sonra bana geçerli aktif uygulama adını göstermelidir. Bazı kodları denedim. Burada görebilirsiniz. Ama zamanlayıcı durduktan sonra bana hiçbir şey göstermiyor.

C# kodu:

public class Win32wrapper 
{ 
    private System.Timers.Timer pingTimer; 
    private Timer recordTimer; 

    private List<HarvestApp.ProcessInformation> ProcessList = new List<HarvestApp.ProcessInformation>(); 

    [DllImport("user32.dll")] 
    public static extern IntPtr GetForegroundWindow(); 

    [DllImport("user32.dll")] 
    public static extern IntPtr GetWindowThreadProcessId(IntPtr hWnd, out uint processId); 

    private DateTime recordStartTime; 

    public void startTimer(int pingTimerValue=5000, int recordTimerValue=20000) 
    { 

     pingTimer = new System.Timers.Timer(pingTimerValue); 
     pingTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent); 
     pingTimer.Interval = pingTimerValue; 
     pingTimer.Enabled = true; 

     recordTimer = new Timer(recordTimerValue); 
     recordTimer.Elapsed += new ElapsedEventHandler(OnRecordEvent); 
     recordTimer.Interval = recordTimerValue; 
     recordTimer.Enabled = true; 

     recordStartTime = DateTime.Now; 
    } 

    private void OnTimedEvent(object source, ElapsedEventArgs e) 
    { 
     Console.WriteLine("The Ping Elapsed event was raised at {0}", e.SignalTime); 


     //Record through win32dll the application foreground caption 

     GetActiveFileNameTitle(); 

     //Store into collection object, Push into ArrayList, Push into process id 
    } 


    public String GetActiveFileNameTitle() 
    { 
     IntPtr hWnd = GetForegroundWindow(); 
     uint processId; 
     GetWindowThreadProcessId(hWnd, out processId); 
     Process p = Process.GetProcessById((int)processId); 
     //p.MainModule.FileName.Dump(); 
     return p.ProcessName; 
    } 

     private void OnRecordEvent(object source, ElapsedEventArgs e) 
    { 
     Console.WriteLine("The Record Elapsed event was raised at {0}", e.SignalTime); 

     ProcessInformation procTemp = GetMaxRunTimeForApplicationsBetween(recordStartTime, DateTime.Now); 
     Harvest_TimeSheetEntry tempEntry = new Harvest_TimeSheetEntry(procTemp, recordStartTime, DateTime.Now); 

     //Add to the list of the specific day Only not the entire 
     // Globals._globalController.harvestManager._TIMESHEETENTRYDICTIONARY[recordStartTime.Date].Add(tempEntry); 


     Globals._globalController.getDayViewWindow.Dispatcher.BeginInvoke(new Action(delegate() 
     { 
      Globals._globalController.getDayViewWindow.addHarvestEntrytoView(tempEntry); 
     })); 
     //Clean Out the ProcessList? 

     recordStartTime = DateTime.Now; 
    } 


    public void stopTimer() 
    { 
     pingTimer.Stop(); 
     recordTimer.Stop(); 
    }

Düzenleme: Başlık missleading edilir.

sizin Kodu İzleyin:

private void OnTimedEvent(object source, ElapsedEventArgs e) 
{ 
    Console.WriteLine("The Ping Elapsed event was raised at {0}", e.SignalTime); 

    //Record through win32dll the application foreground caption 

    // You miss the output or usage of the return value here. 
    GetActiveFileNameTitle(); 
    // Try 
    var procName = GetActiveFileNameTitle(); 
    Console.WriteLine(procName); 

    //Store into collection object, Push into ArrayList, Push into process id 
} 

Çalışma örneği:

[DllImport("user32.dll")] 
public static extern IntPtr GetForegroundWindow(); 

Önalan Pencere almak ve alıcı:

[DllImport("user32.dll", SetLastError = true)] 
public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId); 

ProcessID belirlemek. ProcessID ile işlemin adını elde edebilirsiniz. Süreç Class : http://msdn.microsoft.com/de-de/library/system.diagnostics.process.mainmodule.aspx

class Program 
{ 
    static void Main(string[] args) 
    { 
     Thread.Sleep(5000); // Test it with 5 Seconds, set a window to foreground, and you see it works! 
     IntPtr hWnd = GetForegroundWindow(); 
     uint procId = 0; 
     GetWindowThreadProcessId(hWnd, out procId); 
     var proc = Process.GetProcessById((int)procId); 
     Console.WriteLine(proc.MainModule); 
     Console.ReadKey(); 
    } 

    [DllImport("user32.dll")] 
    public static extern IntPtr GetForegroundWindow(); 

    [DllImport("user32.dll", SetLastError = true)] 
    public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId); 
}
