### 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 <stdio.h>
    #include <Windows.h>
    #include <TlHelp32.h>

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);
    }
