我有一个 vbscript 脚本，它接受一个 .ico 文件并使用它作为图标创建一个桌面快捷方式，但如果可能的话，我希望能够将脚本需要的所有内容存储在自身中。
【问题讨论】：
WSF，您可以将二进制数据作为Base64 嵌入CDATA 部分。或者，您可以使用常规的VBS 文件并在脚本之后将 Base64 作为 cmets 嵌入。无论哪种情况，您只需要读取 Base64 并将其转换为二进制并将其写入 ICO 文件即可。

我在网上找到了这个名为 Basic Base64- Encode- Decode.vbs 的 Vbscript 您只需将文件拖放到脚本上，然后单击“是”进行编码。并单击“否”以解码 Base64 字符串。
'-- This is a barebones Base64 encoder/decoder. Drop a file onto script and click YES
'-- to encode. Click NO to decode a Base64 string.
'-- This script uses only VBS and FileSystemObject to do its work. The basic function
' of Base64 conversion is to take each 3 bytes of binary data and convert it to 4
' 6-bit units, which allows any data to be stored as plain text because on plain
' text ASCII characters are used. Decoding is the reverse.
' FSO is designed to only handle text data. Special treatment is required to handle
' binary data, but FSO *can* do it. For example, Textstream.ReadAll expects to read
' a string, so it will return file bytes up until the first null byte. But Textstream.Read(length-of-file)
' can be used to read in the entire file as a string, regardless the content. The bytes can
' then be handled by using Asc to convert the string into a numeric array. It's inefficient,
' but it works. When the file is written back to disk the array members are then converted
' back to characters and the whole thing is transferred as a string. That works fine as
' long as one doesn't try to handle it as a string. For instance, checking Len of the string
' returned from DecodeBase64 will only return the position of the first null.
' The vbCrLf option with encoding is to accomodate email, which by tradition
' inserts a return every 76 characters. In other words, these functions can be used
' to create or decode attachments in email. They could also be used to send any type
' of file in the form of text pasted into an email. If the recipient has the decode script
' they can just select and copy the email content, paste it into Notepad, save it as a
' TXT file, then drop it onto the script to convert that text into the original JPG, EXE, or
' any other file type.

与使用@Hackoo 找到的代码相比，在 VBScript 中将二进制数据转换为 Base64 有一种更简单（也更快）的方法。您可以通过使用MSXML2.DOMDocument 类来利用Microsoft 的Base64 实现。这是一个脚本，它采用二进制文件c:\test.jpg 并将其转换为 Base64。生成的 Base64 编码字符串保存在文本文件 (c:\out.txt) 中。它使用ADO Stream 将文件读入二进制数组，然后将其传递给使用DOMDocument 将二进制数据转换为Base64 编码文本的例程。
Const BINARY_FILE = "c:\test.jpg"
Const BASE64_FILE = "c:\out.txt"
With CreateObject("Scripting.FileSystemObject").CreateTextFile(BASE64_FILE, True)
.Write BinaryFileToBase64(BINARY_FILE)
.Close
End With
Function BinaryFileToBase64(strFileName)
With CreateObject("ADODB.Stream")
.Type = 1 ' Specify binary data (adTypeBinary)
.Open
.LoadFromFile strFileName
BinaryFileToBase64 = Base64Encode(.Read) ' Read binary contents into VT_UI1 | VT_ARRAY
End With
End Function
' This function accepts binary (VT_UI1 | VT_ARRAY) data and converts it to Base64-encoded text (Unicode string).
Function Base64Encode(BinaryData) ' As String
With CreateObject("MSXML2.DOMDocument.3.0").CreateElement("Base64")
.DataType = "bin.base64" ' Set the type of data the element should store
.NodeTypedValue = BinaryData ' Write the binary data
Base64Encode = .Text ' Read it back as text
End With
End Function
因此，您可以使用此脚本将任何二进制文件转换为其 Base64 编码的字符串表示形式。例如，这是 Stack Overflow 的图标，保存为 12x15 位图：

要解码 Base64 编码的字符串，我们只需要反向执行这些步骤。首先，我们将文本解码回其原始二进制形式。然后，我们将二进制数据写入文件。
CONST NEW_BINARY_FILE = "c:\test2.jpg"
With CreateObject("Scripting.FileSystemObject").OpenTextFile(BASE64_FILE)
Base64ToBinaryFile .ReadAll(), NEW_BINARY_FILE
.Close
End With
Sub Base64ToBinaryFile(strBase64, strFileName)
With CreateObject("ADODB.Stream")
.Type = 1 ' adTypeBinary
.Open
.Write Base64Decode(strBase64) ' Write the byte array
.SaveToFile strFileName, 2 ' Overwrite if file exists (adSaveCreateOverWrite)
End With
End Sub
Function Base64Decode(ByVal strText) ' As ByteArray
With CreateObject("MSXML2.DOMDocument.3.0").CreateElement("Base64")
.DataType = "bin.base64"
.Text = strText
Base64Decode = .NodeTypedValue
End With
End Function
那么，回到您最初的问题，如何在您的 VBScript 文件中嵌入二进制 (ICO) 文件？您可以在某处添加 Base64 字符串。把它放在结尾，开头，中间的某个地方。但它当然需要被注释掉，因为它不是有效的 VBScript。您可能想要添加一个开始和结束分隔符，以便知道它的开始和结束位置。例如：
' Read ourself...
With CreateObject("Scripting.FileSystemObject").OpenTextFile(WScript.ScriptFullName)
' Look for the "start"...
Do Until .AtEndOfStream
strLine = .ReadLine()
If strLine = "' ~END~" Then fRead = False
If fRead Then strBase64 = strBase64 & Mid(strLine, 3)
If strLine = "' ~START~" Then fRead = True
Loop
End With
' Re-create our bitmap!
Base64ToBinaryFile strBase64, "c:\stack_overflow.bmp"
' ~START~
