关于如何处理二进制数据？

[0004yhy4000]

我有一些二进制数据！想通过VB处理！例如：分析数据或者画出数据曲线等等！不知该如何处理！哪里有这方面的资料？或者类似的程序在那里可以找到？请各位高人指点一二！小弟先谢谢了！

The following routines demonstrate how to write/read data to/from a file. The data can be an array or any simple data type.
Option Explicit
'Purpose : Saves/writes a block of data to a file
'Inputs : vData The data to store in the file. Can be an
' array or any simple data type.
' sFileName The path and file name where the data is to be stored
' [bAppendToFile] If True will append the data to the existing file
'Outputs : Returns True if succeeded in saving data

'Revisions :
Function FileWriteBinary(vData As Variant, sFileName As String, Optional bAppendToFile As Boolean = True) As Boolean
Dim iFileNum As Integer, lWritePos As Long
On Error GoTo ErrFailed
If bAppendToFile = False Then
If Len(Dir$(sFileName)) > 0 And Len(sFileName) > 0 Then
'Delete the existing file
VBA.Kill sFileName
End If
End If
iFileNum = FreeFile
Open sFileName For Binary Access Write As #iFileNum
If bAppendToFile = False Then
'Write to first byte
lWritePos = 1
Else
'Write to last byte + 1
lWritePos = LOF(iFileNum) + 1
End If
Put #iFileNum, lWritePos, vData
Close iFileNum
FileWriteBinary = True
Exit Function
ErrFailed:
FileWriteBinary = False
Close iFileNum
Debug.Print Err.Description
End Function
'Purpose : Reads the contents of a binary file
'Inputs : sFileName The path and file name where the data is stored
'Outputs : Returns an array containing all the data stored in the file.
' e.g. ArrayResults(1 to lNumDataBlocks)
' Where lNumDataBlocks is the number of data blocks stored in file.
' If the file was created using FileWriteBinary, this will be the number
' of times data was appended to the file.

说详细点嘛。什么数据？和什么有关？要怎么处理？（统计？计算？）

[kmzs]

什么呀？？？

太笼统了。
