C++ Win32 遍历窗口

查找指定窗口

#include <iostream>
#include <windows.h>
using namespace std;

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    HWND hWnd = ::FindWindow(L"#32770", L"x32Inject");
    if (hWnd != NULL)
    {
        // 修改窗口标题
        ::SetWindowText(hWnd, L"Hello World!");
    }
    else
    {
        ::MessageBox(0, L"窗口没找到", L"提示", 0);
    }
    return 0;
}

窗口控制

#include <windows.h>

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    HWND hWnd = ::FindWindow(L"#32770", L"x32Inject");
    if (hWnd != NULL)
    {
        // 切换窗口
        SwitchToThisWindow(hWnd, false);
        Sleep(5000);
        // 关闭窗口
        ::SendMessage(hWnd, WM_CLOSE, 0, 0);
    }
    else
    {
        ::MessageBox(0, L"窗口没找到", L"提示", 0);
    }
    return 0;
}

查找子窗口

#include <windows.h>

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    HWND hWnd = ::FindWindow(L"#32770", L"x32Inject");
    if (hWnd != NULL)
    {
        // 查找子窗口
        HWND hEdit = ::FindWindowEx(hWnd, NULL, L"Edit", L"");
        // 设置标题
        ::SetWindowText(hEdit, L"test");
        // 修改内容(本案例，内容和标题是一样的)
        ::SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM)L"Hello World！");
    }
    else
    {
        ::MessageBox(0, L"窗口没找到", L"提示", 0);
    }
    return 0;
}

#include <windows.h>

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    HWND hWnd = ::FindWindow(L"#32770", L"x32Inject");
    if (hWnd != NULL)
    {
        // 查找子窗口
        HWND hEdit = ::GetDlgItem(hWnd, 0x3EA);
        // 获取内容
        ::SendMessage(hWnd, WM_GETTEXT, MAX_PATH, (LPARAM)szTitle);
        // 修改内容
        ::SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM)L"Hello World！");
    }
    else
    {
        ::MessageBox(0, L"窗口没找到", L"提示", 0);
    }
    return 0;
}

枚举子窗口

#include <windows.h>
#include <stdio.h>

BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam)
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    ::GetWindowText(hwnd, szTitle, MAX_PATH);
    ;; MessageBox(0, szTitle, L"子窗口", MB_OK);
    return TRUE;
}

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    HWND hWnd = ::FindWindow(L"#32770", L"x32Inject");
    if (hWnd != NULL)
    {
        ::EnumChildWindows(hWnd, EnumChildProc, NULL);
    }
    else
    {
        ::MessageBox(0, L"窗口没找到", L"提示", 0);
    }
    getchar();
    return 0;
}

枚举所有打开的窗口

#include <windows.h>
#include <stdio.h>

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    ::GetWindowText(hwnd, szTitle, MAX_PATH);
    wprintf(L"%s\n", szTitle);
    if (wcscmp(szTitle, L"x32Inject") == 0)
    {
        ::MessageBox(0, szTitle, L"窗口", 0);
    }
    return TRUE;
}

int main()
{
    ::EnumWindows(EnumWindowsProc, NULL);
    getchar();
    return 0;
}

模拟鼠标点击

#include <windows.h>
#include <stdio.h>
// 隐藏控制台运行
#pragma comment(linker,"/subsystem:\"windows\"  /entry:\"mainCRTStartup\"")     

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    RECT r;
    HWND hWnd = ::FindWindow(L"#32770", L"x32Inject");
    if (hWnd != NULL)
    {
        HWND hButton = ::FindWindowEx(hWnd, NULL, L"Button", L"选择程序");
        // 获取选择程序窗口坐标
        ::GetWindowRect(hButton, &r);
        // 设置鼠标位置
        ::SetCursorPos(r.left + 10, r.top + 10);
        Sleep(3000);
        // 鼠标左键单击
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0); // 按下左键
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);  // 松开左键
    }
    else
    {
        ::MessageBox(0, L"没有找到窗口！", L"提示", MB_OK);
    }
    getchar();
    return 0;
}

模拟键盘点击(搜索：键盘键与虚拟键码对照表)

#include <windows.h>
#include <stdio.h>
// 隐藏控制台运行
#pragma comment(linker,"/subsystem:\"windows\"  /entry:\"mainCRTStartup\"")     

int main()
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    RECT r;
    HWND hWnd = ::FindWindow(L"#32770", L"SemaphoreEx");
    if (hWnd != NULL)
    {
        HWND hEdit = ::GetDlgItem(hWnd, 0x3E8);
        // 获取选择程序窗口坐标
        ::GetWindowRect(hEdit, &r);
        // 设置鼠标位置
        ::SetCursorPos(r.left + 1, r.top + 1);
        Sleep(1000);
        // 鼠标左键单击
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0); // 按下左键
        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(0, L"没有找到窗口！", L"提示", MB_OK);
    }
    getchar();
    return 0;
}
