通过ShellExecuteEx函数启动时，Install-Shield窗口不会出现在顶部

Question

我正在尝试使用以下代码启动通过install-shield创建的setup.exe

DWORD ChildProcess(LPCSTR exePath, LPCSTR lpCmdLine ,BOOL showDialog, char* workingDir, BOOL bParentWait )
{
    CWnd * handle = AfxGetMainWnd (); //handle to the main dialog box of mfc application
    DWORD dwExitCode = -1;
    SHELLEXECUTEINFO ShExecInfo = {0};
    ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
    ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
    ShExecInfo.lpVerb = "open";
    ShExecInfo.lpFile = exePath; //setup.exe path, installer exe

    if(bParentWait)
    {
        ShExecInfo.lpParameters =   lpCmdLine;
        ShExecInfo.nShow = SW_MINIMIZE;
    }
    else
    {
        ShExecInfo.nShow = SW_SHOW;
        ShExecInfo.lpParameters =   NULL;
    }
    ShExecInfo.lpDirectory = workingDir;

    ShExecInfo.hInstApp = NULL; 
    if (ShellExecuteEx(&ShExecInfo))
    {
        if(bParentWait)
        {

            handle->ShowWindow(SW_MINIMIZE);
            WaitForSingleObject(ShExecInfo.hProcess,INFINITE);  
            if(showDialog){
                handle->ShowWindow(SW_RESTORE);
            }
            GetExitCodeProcess(ShExecInfo.hProcess, &dwExitCode);

        }
        else
        {
            CloseHandle(ShExecInfo.hProcess);
            dwExitCode = 0;
        }
    }

    return dwExitCode;
}

问题是启动的安装程序窗口没有出现在顶部。任何帮助将不胜感激。

我相信你遇到的问题是因为setup.exe会生成另一个执行UI序列的进程（从而显示窗口）。
