ASP Classic - convert base64binary string to byte array

Question

I am trying to convert a base64binary string to an array of bytes in classic ASP. StrConv () does not exist in ASP.

My goal is to take the base64binary string received from the web service call and write the binary format to a file.

thanks,

When I came across a similar situation a while ago, I used MSXML to convert the data into an array of bytes, before you save it to a file, you will need version 3 or higher.

For this you would:

• Load data using MSXML
• Set the node property dataTypetobin.base64
• Read binary data from node using property nodeTypedValue
