窗口操作函数

查找窗口

找window窗口句柄可以使用spy++或者大漠这样的工具，但是在程序重启时句柄会有变化，所以需要使用函数。

#include "stdafx.h"
#include 
#include 
#include 

1、FindWindow + SetWindowText

	//参数：类名 标题
	HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("飞鸽传书  IP Messenger"));
	if (hwnd != NULL)
	{
		//修改窗口标题					
		::SetWindowText(hwnd, TEXT("新的窗口标题"));
	}
	else
	{
		::MessageBox(NULL, TEXT("窗口没有找到"), TEXT("[ERROR]"), MB_OK);
	}

2、FindWindow + dll加载 -> SwitchToThisWindow +  SendMessage

	HWND hwnd = ::FindWindow(TEXT("WeChatLoginWndForPC"), TEXT("登录"));
	if (hwnd) {
		typedef void (WINAPI *PSWITCHTOTHISWINDOW) (HWND, BOOL);
		PSWITCHTOTHISWINDOW SwitchToThisWindow;
		HMODULE hUser32 = LoadLibrary(TEXT("user32.dll"));
		SwitchToThisWindow = (PSWITCHTOTHISWINDOW)GetProcAddress(hUser32, "SwitchToThisWindow");

		//切换窗口：切换到最上层					
		SwitchToThisWindow(hwnd, false);

		Sleep(3000);
		//关闭窗口：最小化 							
		::SendMessage(hwnd, WM_CLOSE, 0, 0);
	}
	else {
		::MessageBox(NULL, TEXT("窗口没有找到"), TEXT("[ERROR]"), MB_OK);
	}

 

查找子窗口

1、方式一： 

	HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("lenovo(LAPTOP-HF4N9SA5)"));
	if (hwnd != NULL)
	{
		//查找子窗口：父窗口句柄 类 标题					
		HWND hEdit = FindWindowEx(hwnd, NULL, TEXT("RichEdit20W"), TEXT(""));
		//设置标题					
		::SetWindowText(hEdit, TEXT("文本框新的标题"));
		//修改内容					
		::SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM)"1");
	}
	else
	{
		::MessageBox(NULL, TEXT("窗口没有找到"), TEXT("[ERROR]"), MB_OK);
	}

2、同类名、同内容的情况(就是上面的那种情况，使用的是飞秋软件)。
使用GetDlgItem函数；
这时候就可以通过控件ID来查找：spy++查找之后确定、右键、属性就可以查看ID，注意此时的ID是16进制的。

	TCHAR szTitle[MAX_PATH] = { 0 };
	HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("lenovo(LAPTOP-HF4N9SA5)"));
	if (hwnd != NULL)
	{
		//查找子窗口					
		HWND hEdit = ::GetDlgItem(hwnd, 0x480);
		//获取内容					
		::SendMessage(hEdit, WM_GETTEXT, MAX_PATH, (LPARAM)szTitle);
		//修改内容					
		::SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM)"111");
	}
	else
	{
		::MessageBox(NULL, TEXT("窗口没有找到"), TEXT("[ERROR]"), MB_OK);
	}
	printf("%s", szTitle);

 

枚举所有子窗口

控件的本质就是窗口，所以这里也可以表示为所有控件；
EnumChildWindows需要传入一个回调函数，重复调用直到遍历完成或者返回False为止。

BOOL CALLBACK EnumChildProc(HWND hWnd, LPARAM lParam)
{
	TCHAR szTitle[MAX_PATH] = { 0 };
	::GetWindowText(hWnd, szTitle, MAX_PATH);
	MessageBox(NULL, szTitle, TEXT("[子窗口]"), MB_OK);
	return true;
}

VOID EnumChildWindow()
{
	TCHAR szTitle[MAX_PATH] = { 0 };
	HWND hWnd = ::FindWindow(TEXT("#32770"), TEXT("新的窗口标题"));
	if (hWnd != NULL)
	{
		::EnumChildWindows(hWnd, EnumChildProc, 0);
	}
	else
	{
		::MessageBox(NULL, TEXT("窗口没有找到"), TEXT("[ERROR]"), MB_OK);
	}
}

 

枚举所有打开窗口

BOOL CALLBACK EnumOpenWindowProc(HWND hWnd, LPARAM lParam)
{
	TCHAR szTitle[MAX_PATH] = { 0 };
	::GetWindowText(hWnd, szTitle, MAX_PATH);
	//MessageBox(NULL, szTitle, TEXT("[窗口]"), MB_OK);
	if (lstrcmpW(szTitle, TEXT("登录")) == 0)
	{
		MessageBox(NULL, szTitle, TEXT("[窗口]"), MB_OK);
		return FALSE;
	}
	return TRUE;
}
VOID EnumOpenWindows()
{
	EnumWindows(EnumOpenWindowProc, NULL);
}

 

模拟鼠标事件

隐藏控制台	
	
#pragma   comment(linker,"/subsystem:\"windows\"  /entry:\"mainCRTStartup\""   ) 	
	
模拟鼠标单击	
	
	
TCHAR szTitle[MAX_PATH] = {0};	
RECT r;	
HWND hwnd = ::FindWindow(TEXT("#32770"),TEXT("飞鸽传书  IP Messenger"));	
if(hwnd != NULL)	
{	
	HWND hButton = FindWindowEx(hwnd,NULL,"Button","刷新(&R)");
	
	//获取窗口坐标
	::GetWindowRect(hButton,&r);
	
	printf("%d %d",r.left,r.top);
	
	//设置鼠标的位置
	::SetCursorPos(r.left+10,r.top+10);
	Sleep(2000);
	//鼠标左键单击
	mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);//点下左键 
	mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);//松开左键
}	
else	
{	
	::MessageBox(NULL,TEXT("窗口没有找到"),TEXT("[ERROR]"),MB_OK);
}	

 

模拟键盘事件

模拟键盘点击(搜索：键盘键与虚拟键码对照表)	
	
	
TCHAR szTitle[MAX_PATH] = {0};	
RECT r;	
HWND hwnd = ::FindWindow(TEXT("#32770"),TEXT("飞鸽传书  IP Messenger"));	
if(hwnd != NULL)	
{	
	//HWND hButton = FindWindowEx(hwnd,NULL,"Button","刷新(&R)");
	HWND hEdit =::GetDlgItem(hwnd,0x3E9);
	
	//获取窗口坐标
	::GetWindowRect(hEdit,&r);
	
	//设置鼠标的位置
	::SetCursorPos(r.left+1,r.top+1);
	Sleep(1000);
	
	//鼠标左键单击
	mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);//点下左键 
	mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);//松开左键
	
	//模拟键盘
	keybd_event(97,0,0,0);
	keybd_event(97,0,KEYEVENTF_KEYUP,0);
	Sleep(1000);
	keybd_event(66,0,0,0);
	keybd_event(66,0,KEYEVENTF_KEYUP,0);
	Sleep(1000);
	keybd_event(16,0,0,0);
	keybd_event(67,0,0,0);
	keybd_event(67,0,KEYEVENTF_KEYUP,0);
	keybd_event(16,0,KEYEVENTF_KEYUP,0);
	
}	
else	
{	
	::MessageBox(NULL,TEXT("窗口没有找到"),TEXT("[ERROR]"),MB_OK);
}	

 

可以完成一个模拟QQ登录的功能。
