请教各位大虾，急！！！

我在WIN2000，如下代码：
DWORD outCount;
unsigned int inBuffer;
unsigned int outBuffer;
DWORD bW;
BOOL status;
HANDLE hDevice;

hDevice = CreateFile(\"\\\\\\\\.\\\\LPT1\",
GENERIC_READ | GENERIC_WRITE,
0, // share mode none
NULL, // no security
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL ); // no template
if (hDevice == INVALID_HANDLE_VALUE) {
AfxMessageBox(\"Failed to obtain file handle to device: \");}

outBuffer=0xFF;
outCount=sizeof(outBuffer);
status = WriteFile(hDevice, &outBuffer, outCount, &bW, NULL);
if (!status) {AfxMessageBox(\"Failed on call to WriteFile - error: \");}
else{AfxMessageBox(\"Succeeded in writing bytes\");}

status = CloseHandle(hDevice);
if (!status)  {
AfxMessageBox(\"Failed on call to CloseHandle - error:\");}
else{
AfxMessageBox(\"Succeeded in closing device...exiting normally\");}

我一运行就死机，是什么问题？
