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
与&
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 buff
s 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()
