关于releasebuffer的问题

Question

CString filenamebuf,mophonebuf;
GetPrivateProfileString("SetVoiceInfo","VoiceFile","",filenamebuf.GetBuffer(filenamebuf.GetLength()),255,"./INI/ibsc_config.ini");
GetPrivateProfileString("SetVoiceInfo","MoPhone","",mophonebuf.GetBuffer(filenamebuf.GetLength()),255,"./INI/ibsc_config.ini");
m_palyfilename = filenamebuf;
m_strMoNum = mophonebuf;
m_palyfilename.ReleaseBuffer();
mophonebuf.ReleaseBuffer();
这段程序家最后两句出错，不加可以调试通过并结果正确。
但是，总觉得有空间没有释放，会存在潜在的危险。
请问高手们，这是怎么回事，并能不吝赐教！

Answer 1

//试试这样：CString filenamebuf,mophonebuf; 
GetPrivateProfileString("SetVoiceInfo","VoiceFile","",filenamebuf.GetBuffer(filenamebuf.GetLength()),255,"./INI/ibsc_config.ini"); 
GetPrivateProfileString("SetVoiceInfo","MoPhone","",mophonebuf.GetBuffer(filenamebuf.GetLength()),255,"./INI/ibsc_config.ini"); filenamebuf.ReleaseBuffer();
mophonebuf.ReleaseBuffer();m_palyfilename = filenamebuf; 
m_strMoNum = mophonebuf; m_palyfilename.ReleaseBuffer(); 
mophonebuf.ReleaseBuffer(); 

Answer 2

m_palyfilename.ReleaseBuffer(); 错了->  filenamebuf.ReleaseBuffer(); 

Answer 3

//试试直接使用 m_palyfilename 和 m_strMoNum 来获取数据。GetPrivateProfileString("SetVoiceInfo","VoiceFile","",m_palyfilename.GetBuffer(255),255,"./INI/ibsc_config.ini"); 
GetPrivateProfileString("SetVoiceInfo","MoPhone","",m_strMoNum.GetBuffer(255),255,"./INI/ibsc_config.ini"); m_palyfilename.ReleaseBuffer();
m_strMoNum.ReleaseBuffer();

Answer 4

filenamebuf.GetBuffer(filenamebuf.GetLength())
你的filenamebuf.GetLength为0,你的GetBuffer如何能成功
改为filenamebuf.GetBuffer(255);

Answer 5

我试了一下！是releasebuffer放的位置不对，应该紧跟使用getbuffer那句。谢谢各位散分！
