Re: Some question about CString,Unicode ,and TCHAR *

LPCTSTR is only a pointer which point to the temp string,
COptions::Stora gePath+_T("\\te st\\")+pWData-cFileName; will construct
a temp CString ,but after that it will be destroyed, and the pointer
will point to a invalid memory.

by the way, please do not post Chinese charator in your question, here
is a international mailist, so many people can not read in Chinese.

and the type of upload function is:
UINT WRMCC_RequestUp loadFile ( LPCTSTR lpszMyFilePath, LPCTSTR
lpszPeerFilePat h=NULL, FUNC_FTNOTIFY_C allback
Proc_FTNOTIFY_C allback=NULL, BOOL bForceRetransmi t=FALSE );
