[求助]请教高手，我的写文件程序哪里有错误。

我运行了下面的代码后，复制后的图像特别模糊，请问这是怎么回事
如果我复制的是文本文件，复制后的文本文件里面有乱码。
请高手帮我查查哪里错了。谢谢。
Dim FreeF As Integer
Dim LenFile As Long
Dim nCnt As Long
Dim LocData As String
FreeF = FreeFile
Open "f:\desktop.bmp" For Binary As #99
Open "f:\1.bmp" For Binary As #1
nCnt = 1
LenFile = LOF(99)
Do Until nCnt > (LenFile)
LocData = Space$(4096)
  Get #99, nCnt, LocData
   If nCnt + 4096 > LenFile Then
     Put #1,ncnt , Mid$(LocData, 1, (LenFile - nCnt) )
   Else
   Put #1, nCnt, LocData
  End If
   nCnt = nCnt + 4096
Loop
Close #99

为什么要复制了
直接用filecopy  就可以了

问题在此，LocData = Space$(4096)
你读的是二进制数据，却用的是字符串暂存，字符串遇到0表示终止，你应该使用Byte数组。

谢谢版主了，我试试
