不知道为什么，老提示 实时错误 类型不匹配
在写access数据二进制图片时候，如下代码：

Dim NumBlocks As Integer
Dim LeftOver As Long
Dim byteData() As Byte '字节数组
Dim DestFile As Integer, i As Integer
Dim ColSize As Long
Dim BlockSize As Integer
BlockSize = 256
ColSize = Col.ActualSize
DestFile = FreeFile
Open filename For Binary Access Write As DestFile
NumBlocks = ColSize \ BlockSize
LeftOver = ColSize Mod BlockSize
If Col.Type = adLongVarBinary Then
If LeftOver > 0 Then
ReDim byteData(LeftOver)
byteData() = Col.GetChunk(LeftOver)
‘Col.GetChunk (LeftOver)
Put DestFile, , byteData()
End If
ReDim byteData(BlockSize)
For i = 1 To NumBlocks
byteData() = Col.GetChunk(BlockSize)
’Col.GetChunk (BlockSize)
Put DestFile, , byteData()
Next
End If
Close DestFile


到byteData() = Col.GetChunk(BlockSize)这一行老提示：：

实时错误 类型不匹配

------解决方案--------------------

Binary类型的最好用command+parameter来写。

请仔细对照上面地址的代码和分析。
[解决办法]
set byteData = Col.GetChunk(BlockSize)
