为何调用CreateProcess时出错？

[fenex]

调用语句如下：
CreateProcess(strFileName, NULL, NULL, NULL, FALSE, NULL, NULL, strDirectory, NULL, NULL)；
程序执行这句后出错并退出，请问是哪个参数不对，应该如何修改？
我的OS是Win2000

用GetLastError()查差！

你的后两个参数不对，不能为NULL，必须传入参数才可以。
下面是msdn给的例子，希望对你有些帮助。

STARTUPINFO si;
PROCESS_INFORMATION pi;

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

// Start the child process.
if( !CreateProcess( NULL, // No module name (use command line).
"MyChildProcess", // 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.
)
{
ErrorExit( "CreateProcess failed." );
}

// Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );

// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
