c - 使用 CreateProcess，无法获取 CREATE_NO_WINDOW 来抑制控制台

Question

我想在不弹出控制台窗口的情况下启动一个进程(为简单起见，我们将使用记事本)。

我确定我错过了一些非常简单的东西，这是我最简化的测试用例:

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

void _tmain( int argc, TCHAR *argv[] )
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );

    // Start the child process. 
    if( !CreateProcess( NULL,   // No module name (use command line)
        "notepad",        // Command line
        NULL,           // Process handle not inheritable
        NULL,           // Thread handle not inheritable
        FALSE,          // Set handle inheritance to FALSE
        CREATE_NO_WINDOW,              // No creation flags
        NULL,           // Use parent's environment block
        NULL,           // Use parent's starting directory 
        &si,            // Pointer to STARTUPINFO structure
        &pi )           // Pointer to PROCESS_INFORMATION structure
    ) 
    {
        printf( "CreateProcess failed (%d).\n", GetLastError() );
        return;
    }

    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );

    // Close process and thread handles. 
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

您正在从父进程(您的控制台应用程序)创建一个新进程(notepad.exe)，并让父进程等待子进程完成。控制台窗口是父进程的主窗口。您可以隐藏和恢复如下所示。

// Notice how hiding the console window causes it to disappear from
// the Windows task bar. If you only want to make it minimize, use
// SW_MINIMIZE instead of SW_HIDE.
void _tmain(int argc, TCHAR *argv[])
{
    ShowWindow( GetConsoleWindow(), SW_HIDE );

    // create a new process and wait for it to finish

    ShowWindow( GetConsoleWindow(), SW_RESTORE );
}
