当我使用createprocess时如何隐藏gui [英] how to hide the gui when i use createprocess

问题描述

你好朋友，
我使用createprocess函数打开一个现有的应用程序，例如"calc.exe".但是如何隐藏gui界面?STARTUPINFO成员``wShowWindow=SW_HIDE''不起作用.

hello friend,
I use createprocess function open an exist app such as ''calc.exe''. But how can i hide the gui interface?The STARTUPINFO member ''wShowWindow=SW_HIDE'' doesn''t work.

PROCESS_INFORMATION pi;
STARTUPINFO si;
memset(&si,0,sizeof(si));
si.cb=sizeof(si);
si.dwFlags=STARTF_USESHOWWINDOW;
si.wShowWindow=SW_HIDE;
BOOL fRet=CreateProcess(_T("C:\\Windows\\system32\\calc.exe"),
                        NULL,
                        NULL,
                        FALSE,
                        NULL,
                        NULL,
                        NULL,
                        NULL,
                        &si,
                        &pi);

推荐答案

我怀疑这与calc.exe本身无关，而与此参数无关.我刚刚使用测试程序对其进行了尝试，并且可以正常工作，如文档中所述.

I suspect that this is something to do with calc.exe itself ignoring this parameter. I have just tried it with a test program and it works correctly, as described in the documentation.
