高手救命:用writefile向gdb写命令为什么它不执行?

只是个实验版本:

tmp = szFilename;//路径加文件名
HANDLE hRead = NULL;
HANDLE hWrite = NULL;
SECURITY_ATTRIBUTES sad;
STARTUPINFO suid;
PROCESS_INFORMATION pid;
sad.bInheritHandle = TRUE;
sad.lpSecurityDescriptor = NULL;
sad.nLength = sizeof(SECURITY_ATTRIBUTES);

if(NULL == hRead || NULL == hWrite )
{
if(!CreatePipe(&hRead,&hWrite,&sad,0))//创建匿名管道
{
AfxMessageBox("创建匿名管道失败");
Complying = 0;
return -1;
}
}

ZeroMemory(&suid,sizeof(STARTUPINFO));
suid.cb = sizeof(STARTUPINFO);
GetStartupInfo(&suid);
suid.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
suid.wShowWindow = SW_SHOW;
suid.hStdInput = /*GetStdHandle(STD_INPUT_HANDLE);//*/hRead;
suid.hStdOutput = /*GetStdHandle(STD_OUTPUT_HANDLE);//*/hWrite;
suid.hStdError = /*GetStdHandle(STD_ERROR_HANDLE);//*/hWrite;
tmp = "D:\\MinGWStudio\\MinGW\\bin\\gdb.exe -x -v " + tmp;
