我想在计时器停止时获取当前活动应用程序的名称。录制20秒后,它应显示当前活动的应用程序名称。我尝试了一些代码。你可以在这里看到。但是在计时器停止后它没有向我显示任何内容。
C#代码:
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();
}

编辑:标题是误导性的。
观看您的代码:
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
}
工作示例:
[DllImport("user32.dll")]
public static extern IntPtr GetForegroundWindow();
获取前景窗口并且:
[DllImport("user32.dll", SetLastError = true)]
public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);
确定ProcessID。使用ProcessID,您可以获取进程的名称。 使用流程类: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);
}
