为何小弟我用CreateProcessW()方式运行C:\db\bin\mysqld -init-file=C:\db\my.ini会出现创建线程失败

为何我用CreateProcessW()方式运行C:dbbinmysqld –init-file=C:dbmy.ini会出现创建线程失败?

执行函数如下:

CString ExecuteCommandLine(CString strCmdLine)

{

SECURITY_ATTRIBUTES sa;

HANDLE hRead,hWrite;

sa.nLength = sizeof(SECURITY_ATTRIBUTES);

sa.lpSecurityDescriptor = NULL;

sa.bInheritHandle = TRUE;

if (!CreatePipe(&hRead,&hWrite,&sa,0)) {

MessageBox(_T(“Error On CreatePipe()”));

return _T(“”);

}

STARTUPINFO si;

PROCESS_INFORMATION pi;

si.cb = sizeof(STARTUPINFO);

GetStartupInfo(&si);

si.hStdInput=NULL; 

si.hStdError = hWrite;

si.hStdOutput = hWrite;

si.wShowWindow = SW_HIDE;

si.dwFlags = STARTF_USESHOWWINDOW|STARTF_USESTDHANDLES;

if (!CreateProcessW(NULL,strCmdLine.GetBuffer(), 

NULL,NULL,TRUE,REALTIME_PRIORITY_CLASS,NULL,NULL,&si,&pi)) {

MessageBox(_T(“Error on CreateProcess()”));

return _T(“”);

}

CloseHandle(hWrite);

char buffer[4096] = {0};

CString strBuffer;

DWORD bytesRead = 0;

do{

bytesRead = 0;

memset(buffer, 0, sizeof(buffer));

ReadFile(hRead,buffer,4096,&bytesRead,NULL);

strBuffer += buffer;

}while( bytesRead == 4096);

// Wait until child processes exit.

WaitForSingleObject( pi.hProcess, 0 );

// Close process and thread handles.

CloseHandle( pi.hProcess );

CloseHandle( pi.hThread );

return strBuffer;

}

这是创建进程，不是创建线程。。。。。

最好去MFC版面问。
