c++ - 通过 C++ 运行命令时隐藏控制台窗口

Question

我使用 CreateProcess 运行命令并使用 CREATE_NO_WINDOW 标志，但控制台弹出一小部分时间，如何避免它？

STARTUPINFO si;
PROCESS_INFORMATION pi;

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

CreateProcess
( 
NULL,                // No module name (use command line)
command,             //set env variable and use it is my command
NULL,                // Process handle not inheritable
NULL,                // Thread handle not inheritable
FALSE,               // Set handle inheritance to FALSE
CREATE_NO_WINDOW,    //don't create window but it appears for fraction of second!
NULL,                // Use parent's environment block
NULL,                // Use parent's starting directory
&si,                 // Pointer to STARTUPINFO structure
&pi                  // Pointer to PROCESS_INFORMATION structure
)  

提前感谢您的帮助。

Answer 1

In your STARTUPINFO structure, set the STARTF_USESHOWWINDOW flag in the dwFlags member, and set wShowWindow to SW_HIDE.

Answer 2

你必须重定向你的输出。有一个成员hStdOutput，hStdError应该重定向。这里在 MSDN 上是一个例子。
