QProcess调用外部程序不显示界面

 1 include <Windows.h>
 2     QString program = "C:/Windows/System32/notepad.exe";
 3     QProcess *myProcess = new QProcess();
 4     myProcess->setCreateProcessArgumentsModifier([](QProcess::CreateProcessArguments *args)
 5     {
 6         args->startupInfo->wShowWindow = SW_HIDE;
 7         args->startupInfo->dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
 8     }
 9     );
10     myProcess->start(program, QStringList());

 第二种方法

 1 QString program = "C:/Windows/System32/notepad.exe";
 2 
 3 STARTUPINFO si;
 4 PROCESS_INFORMATION pi;
 5 si.cb = sizeof(STARTUPINFO);
 6 GetStartupInfo(&si);
 7 si.wShowWindow = SW_HIDE;
 8 si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
 9 
10 if (!CreateProcess(NULL, (LPWSTR)program.utf16(),NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))
11 {
12 
13 }

今天在项目内遇到的问题,需要调用外部程序,但不能显示此程序界面,在网上找了一下,调试出这两种方法。
