Hi, I'm trying to upload a binary file to a third party website using objHTTP = CreateObject("MSXML2.ServerXMLHTTP.3.0"). I've managed to log in to their system via their API, and navigate their folder system. I can upload text files, but I have a problem with binary files. The issue is I have to put some text at the start of the file, specifically...

--NEXT_PART_4578577.12021
Content-Disposition: form-data; name="options"
{
"folder" : "aa28796xxxxxxxxxxx0e54c",
"filename" : "C:\\Data\\filename.ext",
"name" : "xyxyxyxyxyx",
"description" : "xyxyxyxy"
}
--NEXT_PART_4578577.12021
Content-Disposition: form-data; name=file1; filename="C:\\Data\\filename.ext"
Content-Type : text/plain
.

My process is to create a string (sOutputData) with the equal to the stuff above (I stream the contents of the text file in the .... bit using NotesStream.ReadText). Having setup our sOutputData string, I then send it (see below) and it works!
Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP.3.0")
objHTTP.Open "POST", sTargetURL & "/resources" & "?p10=" & g_sAPIKey & "&p20=" & g_sUserUUID & "&folderuuid=" & varChosenFolderItems("folderuuid"), False
objHTTP.SetRequestHeader "Cookie", g_sCookie
objHTTP.SetRequestHeader "Content-Type", "multipart/form-data; boundary=" & sBoundary' & "; Charset=Unicode"
objHTTP.Send(sOutputData)

This works fine for text and NotesStream.ReadText (stream.ReadText returns a string, whereas stream.Read returns a variant array of bytes). But if I try to include my binary file stream in the middle of the sOutputData string I get "Type Mismatch"!!!

Has anybody got any ideas?

Regards
Tim
