请教一个字符串操作问题
外星人oo 2006-11-22 09:14:00 TFileName filePath = PathInfo::PhoneMemoryRootPath();
filePath.Append(PathInfo::VideosPath());
TBuf <32> timeAsText;
TTime currentTime;
currentTime.HomeTime();
_LIT ( KTimeFormat, "%1_%2_%3_%H_%T_%S" );
currentTime.FormatL( timeAsText, KTimeFormat ) ;
filePath.Append(timeAsText);
得到的filePath中timeAsText尾部有乱码
TDes16 &aText 又是什么意思
