ADODBStream.Write() should not throw for certain types of binary data #6

Closed bobbystacksmash closed 6 years ago

bobbystacksmash commented 6 years ago

ADODB Streams in binary mode will throw when .write() is called with createable JScript types (strings, objects, etc).

However, .write() will work if it's called passed some kind of COM binary type, such as the .ResponseBody returned from the XHR instance.

We need a mechanism whereby we are able to tell .write() we're giving it binary data. Perhaps a write_arg instanceOf Buffer check would suffice?
