我開發了響應低級別鼠標點擊的C#應用程序。我用鼠標鉤來做到這一點。該應用程序工作正常,每當我點擊任何窗口它響應並執行一些任務。但我想在這裏做一個修改。我想要在窗口上的任何按鈕上執行單擊時響應鼠標點擊。如果我點擊窗口的平坦區域,它不應該回應。目前它響應無論我點擊。我找不到如何識別我是否點擊了按鈕。鼠標鉤,僅在點擊按鈕時才作出響應
這是我的代碼:
private IntPtr SetHook(MouseHookHandler proc)
{
using (ProcessModule module = Process.GetCurrentProcess().MainModule)
return SetWindowsHookEx(WH_MOUSE_LL, proc, GetModuleHandle(module.ModuleName), 0);
}
private IntPtr HookFunc(int nCode, IntPtr wParam, IntPtr lParam)
{
if (nCode >= 0)
{
if (MouseMessages.WM_LBUTTONUP == (MouseMessages)wParam)
if (LeftButtonUp != null)
LeftButtonUp((MSLLHOOKSTRUCT)Marshal.PtrToStructure(lParam, typeof(MSLLHOOKSTRUCT)));
if (MouseMessages.WM_RBUTTONUP == (MouseMessages)wParam)
if (RightButtonUp != null)
RightButtonUp((MSLLHOOKSTRUCT)Marshal.PtrToStructure(lParam, typeof(MSLLHOOKSTRUCT)));
}
return CallNextHookEx(hookID, nCode, wParam, lParam);
}
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
public int x;
public int y;
}
[StructLayout(LayoutKind.Sequential)]
public struct MSLLHOOKSTRUCT
{
public POINT pt;
public uint mouseData;
public uint flags;
public uint time;
public IntPtr dwExtraInfo;
}
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr SetWindowsHookEx(int idHook,
MouseHookHandler lpfn, IntPtr hMod, uint dwThreadId);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool UnhookWindowsHookEx(IntPtr hhk);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam);
[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr GetModuleHandle(string lpModuleName);
請幫我解決這個問題。謝謝。
謝謝您的重播。現在我添加了下面的代碼: IntPtr win = WindowFromPoint(ms.pt); 我得到了窗口句柄作爲勝利。現在我可以通過傳遞'win'句柄的光標位置來使用GetChildAtPoint()嗎?或任何其他建議? – Vignesh
我試圖使用ControlFromHandle將intptr'win'轉換爲Control,並且它始終返回null。如果成功,我可以調用GetChildAtPoint()方法。 – Vignesh
ControlFromHandle僅適用於您的正常流程。嘗試GetClassName或GetWindowText(都是原生函數,所以使用pinvoke) –
