【WPF】C#获取运行的窗体标题

方法1：

XP任务栏结构解析:http://www.shengerzi.com/zhinan/?action-viewnews-itemid-10199

1.整个任务栏的类名为Shell_TrayWnd
2.其下分为了三个区：开始按钮，中间任务栏和右下角任务栏:
1)开始按钮: 类名为BUTTON,标题为"开始",控件ID为0x130
2)中间任务栏:类名为ReBarWindow32，控件ID为0xA005,其下又有三个子窗口:
i.快速启动栏: 类名:ToolbarWindow32,Title:Quick Launch
ii.正在运行程序栏:类名:MSTaskSwWClass,Title:运行应用程序;再其下又有一个类名:ToolbarWindow32,Title:
运行应用程序
iii.文字输入语言栏:类名:CiceroUIWndFrame,Title:TF_FloatingLangBar_WndTitl e
3.右下角任务栏:类名:TrayNotifyWnd,其下有也有三个子窗口:
1)时间显示栏:类名:TrayClockWClass,Title:当前时间如19:00
2)主要显示栏:类名:SysPager,其下有个子窗口，就是我们最常见的最小化到右下角任务栏的地方:类名:
ToolbarWindow32,Title:通知区域
3)一个button,类名:Button, 控件ID为0x5DE

 

 

遗留问题：查询出来的：不止运行中的窗体，还有多出来的几个，例如WinWindows Explorer,360se,Mozilla Firefox,vshost.exe,Microsoft Visual Studio 2008等一些后台的东西。

 

方法2:

private int m_ProcessorCount = 0; //CPU个数 private PerformanceCounter pcCpuLoad; //CPU计数器 private long m_PhysicalMemory = 0; //物理内存 private const int GW_HWNDFIRST = 0; private const int GW_HWNDNEXT = 2; private const int GWL_STYLE = (-16); private const int WS_VISIBLE = 268435456; private const int WS_BORDER = 8388608; #region AIP声明 [DllImport("IpHlpApi.dll")] extern static public uint GetIfTable(byte[] pIfTable, ref uint pdwSize, bool bOrder); //函数功能：该函数返回与指定窗口有特定关系（如Z序或所有者）的窗口句柄。 //函数原型：HWND GetWindow（HWND hWnd，UNIT nCmd）； //参数： //hWnd:窗口句柄。要获得的窗口句柄是依据nCmd参数值相对于这个窗口的句柄。 //nCmd:说明指定窗口与要获得句柄的窗口之间的关系。该参数值可以是下列之一： //GW_CHILD：如果指定窗口是父窗口，则获得的是在Z序顶端的子窗口的句柄，否则为 NULL。函数仅检查指定父窗口的子窗口，不检查继承窗口。 //GW_ENABLEDPOPUP：（WindowsNT 5.0）返回的句柄标识了属于指定窗口的处于使能状态弹出式窗口（检索使用第一个由GW_HWNDNEXT 查找到的满足前述条件的窗口）；如果无使能窗口，则获得的句柄与指定窗口相同。 //GW_HWNDFIRST：返回的句柄标识了在Z序最高端的相同类型的窗口。如果指定窗口是最高端窗口，则该句柄标识了在Z序最高端的最高端窗口；如果指定窗口是顶层窗口，则该句柄标识了在z序最高端的顶层窗口：如果指定窗口是子窗口，则句柄标识了在Z序最高端的同属窗口。 //GW_HWNDLAST:返回的句柄标识了在z序最低端的相同类型的窗口。如果指定窗口是最高端窗口，则该柄标识了在z序最低端的最高端窗口：如果指定窗口是顶层窗口，则该句柄标识了在z序最低端的顶层窗口；如果指定窗口是子窗口，则句柄标识了在 Z序最低端的同属窗口。 //GW_HWNDNEXT：返回的句柄标识了在Z序中指定窗口下的相同类型的窗口。如果指定窗口是最高端窗口，则该句柄标识了在指定窗口下的最高端窗口：如果指定窗口是顶层窗口，则该句柄标识了在指定窗口下的顶层窗口；如果指定窗口是子窗口，则句柄标识了在指定窗口下的同属窗口。 //GW HWNDPREV：返回的句柄标识了在Z序中指定窗口上的相同类型的窗口。如果指定窗口是最高端窗口，则该句柄标识了在指定窗口上的最高端窗口；如果指定窗口是顶层窗口，则该句柄标识了在指定窗口上的顶层窗口；如果指定窗口是子窗口，则句柄标识了在指定窗口上的同属窗口。 //GW_OWNER：返回的句柄标识了指定窗口的所有者窗口（如果存在）。GW_OWNER与 GW_CHILD不是相对的参数，没有父窗口的含义，如果想得到父窗口请使用GetParent()。例如：例如有时对话框的控件的GW_OWNER，是不存在的 [DllImport("User32")] private extern static int GetWindow(int hWnd, int wCmd); [DllImport("User32")] private extern static int GetWindowLongA(int hWnd, int wIndx); [DllImport("user32.dll")] private static extern bool GetWindowText(int hWnd, StringBuilder title, int maxBufSize); [DllImport("user32", CharSet = CharSet.Auto)] private extern static int GetWindowTextLength(IntPtr hWnd); public const int GCW_ATOM = -32; public const int GCL_CBCLSEXTRA = -20; public const int GCL_CBWNDEXTRA = -18; public const int GCL_HBRBACKGROUND = -10; public const int GCL_HCURSOR = -12; public const int GCL_HICON = -14; public const int GCL_HMODULE = -16; public const int GCL_MENUNAME = -8; public const int GCL_STYLE = -26; public const int GCL_WNDPROC = -24; [DllImport("user32.dll", CharSet = CharSet.Auto)] private static extern int GetClassLong(IntPtr hwnd, int nIndex); #endregion #region 查找所有应用程序标题 /// <summary> /// 查找所有应用程序标题 /// </summary> /// <returns>应用程序标题范型</returns> public static List<string> FindAllApps(int Handle) { List<string> Apps = new List<string>(); int hwCurr; hwCurr = GetWindow(Handle, GW_HWNDFIRST); while (hwCurr > 0) { int IsTask = (WS_VISIBLE | WS_BORDER); int lngStyle = GetWindowLongA(hwCurr, GWL_STYLE); bool TaskWindow = ((lngStyle & IsTask) == IsTask); if (TaskWindow) { int length = GetWindowTextLength(new IntPtr(hwCurr)); StringBuilder sb = new StringBuilder(2 * length + 1); GetWindowText(hwCurr, sb, sb.Capacity); string strTitle = sb.ToString(); if (!string.IsNullOrEmpty(strTitle)) { Apps.Add(strTitle); } } hwCurr = GetWindow(hwCurr, GW_HWNDNEXT); } return Apps; } #endregion
