Pobierz bieżącą aktywną nazwę aplikacji

Question

Chcę uzyskać nazwę aktualnie aktywnej aplikacji po zatrzymaniu mojego licznika. Po nagraniu 20 sekund powinien pokazać mi aktualną nazwę aktywnego programu. Spróbowałem trochę kodu. Możesz zobaczyć tutaj. Ale nie pokazuje mi niczego po zatrzymaniu się stopera.

C# Kod:

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(); 
    }

Edycja: Tytuł jest missleading.

Uważaj Kod:

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 
} 

przykład roboczych:

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

uzyskać Okno planie i:

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

Aby określić ProcessID. Dzięki ProcessID możesz uzyskać nazwę procesu. z klasą Process: 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); 
}
