问题
I am trying to convert a base64binary string to a byte array in classic ASP. StrConv() doesn't exist in ASP.
My objective is to take the base64binary string received from a web service call, and write the binary format to a file.
thanks,

When faced with a similar situation some time ago, I used MSXML to convert the data to a byte array before saving it to a file. You will need version 3 or higher.
To do this you would:
- Load the data with MSXML
- Set the node's dataType property to
bin.base64 - Read the binary data from the node using the nodeTypedValue property
- To save the file you can use the ADODB.Stream component.
A few links on how the to this are below.
