窗口查找操作

#include<windows.h>

void Find()
{
    TCHAR szTitle[MAX_PATH] = {0};
    HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("飞鸽传书 2007 绿色版"));
    if(hwnd != NULL)
    {
        SetWindowText(hwnd, "Hello!");
    }
    else
    {
        MessageBox(NULL, TEXT("NOT FOUND"), TEXT("ERROR"), MB_OK);
    }
}
int main(int argc, char* argv[])
{
    Find();
    return 0;
}

FindWindow第一个参数为类名，第二个参数为标题

#include<windows.h>

typedef void (WINAPI *PSWITCHTOTHISWINDOW) (HWND, BOOL);
void WindowControl()
{
    TCHAR szTitle[MAX_PATH] = {0};
    HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("飞鸽传书 2007 绿色版"));
    if(hwnd != NULL)
    {
        PSWITCHTOTHISWINDOW SwitchToThisWindow;
        HMODULE hUser32 = LoadLibrary("user32.dll");
        SwitchToThisWindow = (PSWITCHTOTHISWINDOW) GetProcAddress(hUser32, "SwitchToThisWindow");

        SwitchToThisWindow(hwnd, TRUE);

        Sleep(3000);
        SendMessage(hwnd, WM_CLOSE, 0, 0);
    }else
    {
        ::MessageBox(NULL, TEXT("NOT FOUND"), TEXT("ERROR"), MB_OK);
    }

}
int main(int argc, char* argv[])
{
    WindowControl();
    return 0;
}

SwitchToThisWindow作用是切换窗口。由于它没有在头文件中声明，所以必须从dll中导入。

#include<windows.h>

void FindChildWindow()
{
    TCHAR szTitle[MAX_PATH] = {0};
    HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("飞鸽传书 2007 绿色版"));
    if(hwnd != NULL)
    {
        /*HWND hEdit = FindWindowEx(hwnd, NULL, TEXT("Edit"), "");
        SetWindowText(hEdit, "HelloWorld!");
        //设置内容
        SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM)"新的内容");
        */
        HWND hEdit = GetDlgItem(hwnd, 0x3E9);
        //获取内容
        SendMessage(hEdit, WM_GETTEXT, MAX_PATH, (LPARAM) szTitle);
        //printf("%s", szTitle);
        SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM) "HelloWorld!");
    }
    else
    {
        MessageBox(NULL, TEXT("NOT FOUND"), TEXT("ERROR"), MB_OK);
    }

}
int main(int argc, char* argv[])
{
    FindChildWindow();
    return 0;
}

查找子窗口的两种方式，第一种是通过父窗口查找子窗口，即使用FindWindowEx。

 FindWindowEx(hwnd,    //父窗口句柄
NULL, 　　　　　　　　　　//子窗口句柄
TEXT("Edit"), 　　　　　 //子窗口类名
"");　　　　　　　　　　　　//子窗口标题
第二种方式是通过GetDlgItem查找。

#include<windows.h>

BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam)
{
    TCHAR szTitle[MAX_PATH] = {0};
    GetWindowText(hwnd, szTitle, MAX_PATH);
    MessageBox(NULL, szTitle, "ChildWindow", MB_OK);
    return true;
}

void EnumChildWindow()
{
    TCHAR szTitle[MAX_PATH] = {0};
    HWND hwnd = ::FindWindow(TEXT("#32770"), TEXT("飞鸽传书 2007 绿色版"));
    if(hwnd != NULL)
    {
        EnumChildWindows(hwnd, EnumChildProc, 0);
    }
    else
    {
        MessageBox(NULL, TEXT("NOT FOUND"), TEXT("ERROR"), MB_OK);
    }
}
int main(int argc, char* argv[])
{
    EnumChildWindow();
    return 0;
}

此程序是遍历子窗口。

#include<windows.h>
BOOL CALLBACK EnumOpenWindowProc(HWND hwnd, LPARAM lParam)
{
    TCHAR szTitle[MAX_PATH] = {0};
    GetWindowText(hwnd, szTitle, MAX_PATH);
    MessageBox(NULL, szTitle, "Windows", MB_OK);
    if(strcmp(szTitle, "飞鸽传书 2007 绿色版") == 0)
    {
        MessageBox(NULL, szTitle, "Windows", MB_OK);
        return false;
    }
    return true;
}

void EnumOpenWindows()
{
    EnumWindows(EnumOpenWindowProc, NULL);
}
int main(int argc, char* argv[])
{
    EnumOpenWindows();
    return 0;
}

枚举所有打开的窗口。

#include<windows.h>
void func()
{

    TCHAR szTitle[MAX_PATH] = { 0 };
    RECT r;
    Sleep(5000);
    HWND hwnd = ::FindWindow(TEXT("TXGuiFoundation"), TEXT("QQ"));
    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(707, 447);
        //Sleep(1000);
        //SetCursorPos(621, 399);
        //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(16, 0, 0, 0);
        keybd_event(83, 0, 0, 0);
        keybd_event(83, 0, KEYEVENTF_KEYUP, 0);
        keybd_event(16, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(69, 0, 0, 0);
        keybd_event(69, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(67, 0, 0, 0);
        keybd_event(67, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(50, 0, 0, 0);
        keybd_event(50, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(48, 0, 0, 0);
        keybd_event(48, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(51, 0, 0, 0);
        keybd_event(51, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(56, 0, 0, 0);
        keybd_event(56, 0, KEYEVENTF_KEYUP, 0);


        keybd_event(16, 0, 0, 0);
        keybd_event(87, 0, 0, 0);
        keybd_event(87, 0, KEYEVENTF_KEYUP, 0);
        keybd_event(16, 0, KEYEVENTF_KEYUP, 0);

        keybd_event(84, 0, 0, 0);
        keybd_event(84, 0, KEYEVENTF_KEYUP, 0);

        SetCursorPos(686, 508);
        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);
    }
}
BOOL CALLBACK EnumOpenWindowProc(HWND hWnd, LPARAM lParam)
{
    TCHAR szTitle[MAX_PATH] = { 0 };
    ::GetWindowText(hWnd, szTitle, MAX_PATH);
    if (strcmp((const char *)szTitle, "QQ") == 0)
    {
        
        return FALSE;
    }
    return TRUE;
}
VOID EnumOpenWindows()
{
    EnumWindows(EnumOpenWindowProc, NULL);
}


void main()
{
    STARTUPINFO si = { 0 };
    PROCESS_INFORMATION pi;
    si.cb = sizeof(si);
    BOOL res = CreateProcess(TEXT("D:\\QQ\\Bin\\QQ.exe"), NULL, NULL, NULL, TRUE, CREATE_NEW_CONSOLE, NULL,NULL,  &si, &pi);
    func();
}

实现QQ自动输入密码并且登陆
