下面我通過代碼為大家分享下C#模擬鼠標(biāo),具體內(nèi)容如下:
想必有很多人在項(xiàng)目開發(fā)中可能遇見需要做模擬鼠標(biāo)點(diǎn)擊的小功能,很多人會在百度過后采用mouse_event這個函數(shù),不過我并不想討論如何去使用mouse_event函數(shù)怎么去使用,因?yàn)槟菦]有多大意義。
- static void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo)
- {
- int x = dx, y = dy;
- edit_position(dwFlags, dx, dy, ref x, ref y);
- IntPtr hWndFromPoint = WindowFromPoint(x, y);
- screen_to_client(hWndFromPoint, ref x, ref y);
- send_message(hWndFromPoint, dwFlags, cButtons, x, y);
- }
上述代碼你發(fā)現(xiàn)了什么?如果你發(fā)現(xiàn)說明你知道了本文到底在寫什么東東 說不定你會有一些興趣看下去,不過想到我如今混那么凄慘 在工地上做干活 不過也還好。
鼠標(biāo)點(diǎn)擊目標(biāo)時會向鼠標(biāo)所點(diǎn)擊目標(biāo)窗口投遞消息,根據(jù)鼠標(biāo)的按鍵、狀態(tài)不同會投遞不同的消息,一個完整的“鼠標(biāo)左鍵單擊”事件過程為“WM_LBUTTONDOWN +
WM_LBUTTONUP”即鼠標(biāo)“先左鍵按下 + 后左鍵抬起”,由于mouse_event可以模擬鼠標(biāo)點(diǎn)擊過程而不是直接性一次完整的鼠標(biāo)單擊過程,所以同樣存在“按下、抬起”
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP | MOUSEEVENTF_MOVE, -450, 0, 1, 0);
mouse_event在沒有提供MOUSEEVENTF_MOVE量時光標(biāo)不會移動到相對位置,“光標(biāo)相對位置=光標(biāo)現(xiàn)行位置+新光標(biāo)位置”如果提供量“MOUSEEVENTF_ABSOLUTE”絕對位置,則會以“新光標(biāo)位置”為準(zhǔn)而不會添加“光標(biāo)現(xiàn)行位置”
- static void edit_position(int dwFlags, int dx, int dy, ref int x, ref int y)
- {
- Point pos = MousePosition;
- x = x + pos.X;
- y = y + pos.Y;
- if ((dwFlags | MOUSEEVENTF_ABSOLUTE) == dwFlags)
- SetCursorPos(dx, dy);
- if ((dwFlags | MOUSEEVENTF_MOVE) == dwFlags)
- SetCursorPos(x, y);
- }
edit_position函數(shù)主要用于對MOUSEEVENTF_MOVE于MOUSEEVENTF_ABSOLUTE
相對/絕對光標(biāo)位置修改的一個支持
- static void send_message(IntPtr hWnd, int dwFlags, int cButtons, int x, int y)
- {
- if ((dwFlags | MOUSEEVENTF_LEFTDOWN) == dwFlags)
- SendMessage(hWnd, WM_LBUTTONDOWN, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_LEFTUP) == dwFlags)
- SendMessage(hWnd, WM_LBUTTONUP, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_RIGHTDOWN) == dwFlags)
- SendMessage(hWnd, WM_RBUTTONDOWN, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_RIGHTUP) == dwFlags)
- SendMessage(hWnd, WM_RBUTTONUP, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_MIDDLEDOWN) == dwFlags)
- SendMessage(hWnd, WM_MBUTTONDOWN, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_MIDDLEUP) == dwFlags)
- SendMessage(hWnd, WM_MBUTTONUP, cButtons, MakeDWord(x, y));
- }
send_message函數(shù)主要用于模擬鼠標(biāo)點(diǎn)擊的過程,上面我提到“先左鍵按下 + 后左鍵抬起”在上面的代碼中你會看的清楚的不得了,如果相反你可以去嘗試一番會有什么后果與其說
不如你們自己做更要來的快些。
- static int MakeDWord(int low, int high)
- {
- return low + (high * Abs(~ushort.MaxValue));
- }
- static int Abs(int value)
- {
- return ((value >> 31) ^ value) - (value >> 31);
- }
- MakeDWord / 合并整數(shù),函數(shù)主要是把兩個short合并為一個int,分為low、high兩部分
- static bool screen_to_client(IntPtr hwnd, ref int x, ref int y)
- {
- bool bRetVal = false;
- Point lpptPos = new Point(x, y);
- if ((bRetVal = ScreenToClient(hwnd, ref lpptPos)))
- {
- x = lpptPos.X;
- y = lpptPos.Y;
- }
- return bRetVal;
- }
- screen_to_client函數(shù)故名思意,它主要用于把屏幕上的坐標(biāo)轉(zhuǎn)換到窗口客戶上對應(yīng)坐標(biāo)
