【问题描述】:
如何将带空格的路径传递给 CreateProcess() 函数?
以下作品
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
if( !CreateProcess(_T("c:\\installer\\ew3d.exe"), // No module name (use command line)
_T("c:\\installer\\ew3d.exe /qr"),//argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // 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 false;
}
//Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
但是如果我像下面的代码那样使用带空格的路径,它就不起作用了。
CreateProcess(_T("c:\\master installer\\ew3d.exe"), // No module name (use command line)
_T("c:\\master installer\\ew3d.exe /qr"),//argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // 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
)
并且引用如下命令也无济于事
CreateProcess(_T("\"c:\\master installer\\ew3d.exe\""), // No module name (use command line)
_T("\"c:\\master installer\\ew3d.exe\" /qr"),//argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // 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
)
什么是带空格的路径的正确通过方式?

刚刚在编辑中发布了对我来说可以的代码 - 不明白为什么它不适合你
-
它在 Windows Vista 32 上,我使用的是 VS 2010。它在不同操作系统上的工作方式会有所不同吗?
