Method

Decodes a Base64 string back to its original form.

Usage

result = DecodeBase64(str [, encoding])

Part	Type	Description
result	String	The decoded value of str.
str	String	The Base64 String to be decoded.
encoding	TextEncoding	Optional: The text encoding of the passed string. If you pass an encoding, is has the same effect as calling DefineEncoding on the returned String.

Notes

The DecodeBase64 function performs the reverse operation of EncodeBase64. An encoded string passed to DecodeBase64 returns the original string.

Sample Code

The following code decodes a string back into ASCII:

Var encoded, decoded As String
encoded = EncodeBase64("How now brown cow.", 0)
decoded = DecodeBase64(encoded)

MessageBox(decoded)
