private void button1_click(object sender, eventargs e)

//驗證當前窗體是乙個正在執行的

if (calculatorhandle == intptr.zero)

執行左鍵按下

//mouse_event(mouseeventflag.leftdown, 775, 1173, 0, uintptr.zero);

執行左鍵鬆開 

//mouse_event(mouseeventflag.leftup, 775, 1173, 0, uintptr.zero);

//獲得焦點 

uint wm_setfocus = 0x07;

sendmessage(calculatorhandle, wm_setfocus, intptr.zero, intptr.zero);

//找子視窗

intptr gg = findwindowex(ff, intptr.zero, "shell embedding", null);

intptr hh = findwindowex(gg, intptr.zero, "shell docobject view", null);

intptr ii = findwindowex(hh, intptr.zero, "internet explorer_server", null);

// a set of calculations.

setforegroundwindow(ii);

sendkeys.sendwait("做實驗-0-");

sendkeys.sendwait("^");

}//得到乙個應用程式視窗的控制代碼.

public static extern intptr findwindow(string lpclassname,

string lpwindowname);

// 啟用應用程式視窗.

[dllimport("user32.dll")]

public static extern bool setforegroundwindow(intptr hwnd);

[dllimport("user32.dll", entrypoint = "sendmessage")]

private static extern int sendmessage(intptr hwnd, int msg, intptr wparam, string lparam);

//sendmessage的三個引數意思分別為

//引數1:接收訊息的控制項的控制代碼

//引數2:訊息型別   比如wm_lbuttondown

//引數3:訊息的附加資訊   比如要傳遞一些文字啊.或者座標資訊

[dllimport("user32.dll", entrypoint = "findwindowex")]

private static extern intptr findwindowex(intptr hwndparent, intptr hwndchildafter, string lpszclass, string lpszwindow);

[dllimport("user32.dll", entrypoint = "findwindowex")]

private static extern intptr findwindowex(intptr hwndparent, int hwndchildafter, string lpszclass, string lpszwindow);

//[flags]

//enum mouseeventflag : uint

// }

}
