Lotusscript save base64 encoded string to file (DLL) - vb.net

Question

[EDIT] I believe i left out my original problem. To me it seems like the issue resides in passing the content of the decoded MIMEEntity to a stream, which i'd like to write out to a file. No matter how i attempt it, i can not get lotus script to write the binary data to the file. If anyone has any helpful opinion/suggestion/etc.., I'd be more then grateful!
[ORIGINAL]
I have the following code
Dim a As String
a = "TVqQAAMAAAAEAAAA//8AALgAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" & _
"AAAAgAAAAA4fug4AtAnNIbgBTM0hVGhpcyBwcm9ncmFtIGNhbm5vdCBiZSBydW4gaW4gRE9TIG1v" & _
...
...
Dim session As New NotesSession
Dim stream As NotesStream
Dim doc As NotesDocument
Dim body As NotesMimeEntity
Dim db As NotesDatabase
Set session = New NotesSession
'Create stream and display properties
Set stream = session.CreateStream
'check if the file exists
If Not stream.Open("C:\\Notes\\update.dll") Then
'if the file doesnot exist then create one and add a time stamp to it
Dim fileNum As Integer
fileNum% = Freefile()
Open "/ww414/notes/ebcdicfile.txt" For Output As fileNum%
Close fileNum%
'this should have created the file. see if it existis now
If Not stream.Open("C:\\Notes\\update.dll") Then
'if the file has not been created yet then let the user know of the error that blocks the operation
Messagebox("Log file Is inaccessible")
End If
End If
Dim b As NotesStream
Set b = session.CreateStream
Call b.WriteText(a)
'==========================================================
'update file with the b64 decoded content
Set db = session.CurrentDatabase
Set doc = db.CreateDocument
session.ConvertMime = False
Set body = doc.CreateMIMEEntity
Call body.SetContentFromText(b, "", ENC_BASE64)
Call body.DecodeContent
content = body.ContentAsText
Call stream.WriteText(content)
'close stream/file open in memory
Call stream.Close()
The problem is, the file gets created, but when it comes to the content, it simply puts a few bytes in it (instead of the 14kb of actual file data)
I have checked a bunch of forums and possible solutions, but none of them seem to work.

Answer 1

So, the solution was even simpler as i thought.
This was a huge help, as the root cause of my issue seemed to be the writing out the binary content to the disk. And that was due to creating the file the wrong way! While the file got created it couldn't output the content properly (for some "Lotus reasons"..)
Either way, taking a coffee break and starting everything from zero helped a lot! The code that worked (for future ref. if someone would need to get such a thing working):
Sub Initialize
Dim a As String
a ="BASE64 ENCODED STRING(In my case it was a DLL)"
Dim session As New NotesSession
Dim stream As NotesStream
Dim doc As NotesDocument
Dim body As NotesMimeEntity
Dim db As NotesDatabase
Set session = New NotesSession
Set stream = session.CreateStream
Dim b As NotesStream
Set b = session.CreateStream
Call b.WriteText(a, EOL_NONE)
Set db = session.CurrentDatabase
Set doc = db.CreateDocument
session.ConvertMime = False
Set mime = doc.CreateMIMEEntity
Call mime.SetContentFromText(b, "application/octet-stream", ENC_BASE64)
Call mime.DecodeContent
If Not(mime Is Nothing) Then
Set stream = session.CreateStream
pathname$ = "c:\temp\test.dll"
If Not stream.Open(pathname$, "binary") Then
Messagebox pathname$,, "Open failed"
Goto ExitSub
End If
Call mime.GetContentAsBytes(stream)
Call stream.Close
Else
Messagebox "Not MIME",, doc.GetItemValue("Subject")(0)
End If
ExitSub:
session.ConvertMIME = True ' Restore conversion
End Sub
