问题描述

我必须将3个二进制文件合并为一个,但是尝试时出现错误.这是我的代码:

I have to concatenate 3 binary files into one, but I am getting an error while I try it. Here is my code:

' This is a simple example of managing binary files in
' vbscript using the ADODB object
dim inStream,outStream
const adTypeText=2
const adTypeBinary=1

' We can create the scream object directly, it does not
' need to be built from a record set or anything like that
set inStream=WScript.CreateObject("ADODB.Stream")

' We call open on the stream with no arguments.  This makes
' the stream become an empty container which can be then
' used for what operations we want
inStream.Open
inStream.type=adTypeBinary

' Now we load a really BIG file.  This should show if the object
' reads the whole file at once or just attaches to the file on
' disk
' You must change this path to something on your computer!
inStream.LoadFromFile(Zip7sSFX)
dim buff1
buff1 = inStream.Read()
inStream.LoadFromFile(Config)
dim buff2
buff2= inStream.Read()
inStream.LoadFromFile(PackName)
dim buff3
buff3= inStream.Read()
' Copy the dat over to a stream for outputting
set outStream=WScript.CreateObject("ADODB.Stream")
outStream.Open
outStream.type=adTypeBinary

dim buff
buff=buff1 & buff2 & buff3

' Write out to a file
outStream.Write(buff)
' You must change this path to something on your computer!
outStream.SaveToFile(OutputFile)

outStream.Close()
inStream.Close()

End Sub

我做错了什么?它抱怨buff类型不匹配.

What I am doing wrong? It complains about buff type mismatch.

推荐答案

您无法将 buff & 并置,因为它们是(byte())变体,相反,您可以直接将其附加到输出流中:

You cannot concatenate your buffs with & as they are (byte())Variants, instead you can append to the output stream directly:

const adTypeText=2
const adTypeBinary=1

dim inStream, outStream

set inStream=WScript.CreateObject("ADODB.Stream")
set outStream=WScript.CreateObject("ADODB.Stream")

inStream.Open
inStream.type=adTypeBinary

outStream.Open
outStream.type=adTypeBinary

inStream.LoadFromFile(Zip7sSFX)
outStream.Write = inStream.Read()

inStream.LoadFromFile(Config)
outStream.Write = inStream.Read()

inStream.LoadFromFile(PackName)
outStream.Write = inStream.Read()

outStream.SaveToFile(OutputFile)

outStream.Close()
inStream.Close()
