启动应用程序并按C ++键

问题描述

我正在尝试启动应用程序，然后按F4键。我已经使用EnumWindows和FindWindow尝试了许多解决方案，但它并没有为我提供所需窗口的HWND。

我将其更改为FindWindow，但这无济于事。 我需要获得HWND，但不知何故。

也许你可以帮助我。

到目前为止，我的代码：

#include <Windows.h>
#include <wchar.h>
#include <iostream>
#include <utility>


const std::string command = "echo hi";
const std::string inserted = "cmd.exe /c " + command + " && exit";

wchar_t desktop_name[] = L"Desktop1";
wchar_t explorer_path[] = L"explorer.exe";
wchar_t explorer_class[] = L"Explorer­WClass";

const DWORD waiting_time = 25;

const WORD VK_ENTER = (WORD) VK_RETURN;
const WORD VK_BACKSPACE = (WORD) VK_BACK;

int main()
{
    // Create desktop
    HDESK hDesk = CreateDesktop(desktop_name,NULL,GENERIC_ALL,NULL);
    if (hDesk == NULL)
    {
        std::cout << "Cannot create virtual desktop" << std::endl;
        Sleep(5000);
        exit(1);
    }

    // Assign thread to desktop
    BOOL switchToDesktop = SetThreadDesktop(hDesk);
    if (!switchToDesktop)
    {
        std::cout << "Cannot switch to virtual desktop" << std::endl;
        exit(1);
    }

    // Open WE on the desktop
    STARTUPINFO si;
    ZeroMemory(&si,sizeof(si));
    si.cb = sizeof(si);
    //si.lpDesktop = desktop_name;
    
    PROCESS_informatION pi;
    ZeroMemory(&pi,sizeof(pi));

    // Create process
    CreateProcess(NULL,explorer_path,FALSE,&si,&pi);
    HANDLE explorer_process = pi.hProcess;
    HANDLE explorer_thread = pi.hThread;

    if (explorer_process == NULL)
    {
        std::cout << "Cannot create explorer on virtual desktop" << std::endl;
        Sleep(5000);
        exit(1);
    }

    Sleep(3000);

    // Find process
    HWND weHandle = FindWindow(explorer_class,0);

    if (weHandle == NULL)
    {
        std::cout << "Cannot find explorer on virtual desktop" << std::endl;
        Sleep(5000);
        exit(1);
    }

    PostMessage(weHandle,WM_CHAR,VK_F4,0);

    CloseHandle(explorer_process);
    CloseHandle(explorer_thread);

    return 0;
}
