ftp上传显示123错误,请帮我看看代码,谢谢.

[hexi1981]

CInternetSession* pSession;
pSession=new CInternetSession();
CFtpConnection* pConn=NULL;

pConn=pSession->GetFtpConnection("192.168.100.28","ftpuser","ftpuser");
pConn->PutFile("E:\temp\begin.mpg","begin.mpg");

pConn->Close();
delete pConn;
pSession->Close();
delete pSession;

错误代码:123,查error lookup显示"文件名,目录名或者卷标语法不正确",以上为我的ftp上传代码的关键部分.请帮我看看有什么问题,谢谢.

E:\temp\begin.mpg-->E:\\temp\\begin.mpg

谢谢,就是这个问题.另外如果
CString a;
a = "E:\temp\begin.mpg"
a.Replace("\","\\");

编译无法通过啊?
