Question

If I have two variables containing binary values, how do I append them together as one binary value? For example, if I used WMI to read the registry of two REG_BINARY value, I then want to be able to concatenate the values.

VBScript complains of a type mismatch when you try to join with the ‘&’ operator.

For the record, I wanted VBScript code for a large userbase as a logon script that has the least chance of failing. I like the ADO objects, but there are so many mysterious ways ADO can be broken, so I shy away from ADODB.Stream.

Instead, I was able to write conversion code to convert binary to hex encoded strings. Then, to write back to a REG_BINARY value, I convert it to an array of integers and give it to the SetBinaryValue WMI method.

Note: WshShell can only handle REG_BINARY values containing 4 bytes, so it’s unusable.

Thank you for the feedback.
