FILE* stream=NULL;
                int iFileHandle=0;
                int iFileLen = 0;
                char *pszBuffer;
                DataBf = new float[DataNum];   //DataNum = 5440

                stream = fopen("D:\\mjlee\\testmm.txt", "w");

                if (OpenDialog->Execute())
                {
                        iFileHandle = FileOpen(OpenDialog->FileName, fmOpenRead|fmShareCompat);

                        if(iFileHandle == -1)
                        {
                                ShowMessage("File Open Error");
                                return;
                        }

                        iFileLen = FileSeek(iFileHandle, 0, 2);
                        FileSeek(iFileHandle, 0, 0);
                        pszBuffer = new char[iFileLen+1];

                        FileRead(iFileHandle, pszBuffer, iFileLen);

위에 있는 것처럼 coding을 해서 파일을 읽어 들여서 pszBuffer에 값을 넣었는데...
이값을 float형 DataBf에 넣고 싶은데 어떻게 해야 될지 잘 모르겠습니다.
도움 바람니다.
