Hi All,
Is there a standard WinAPI function or how to encode an executable or a zip 
file in multi-part http POST request?
Encoding type required can be read from the registry HKLM\Software\Classes\
Default is "application/octet-stream".

Thanks,
Vladimir

No WinAPI function, but any base64 mechanism works.

Phil,
I created an html file with 2 inputs - text and file. Attached an executable 
and compared the message body which contained an attachment and the 
attachment (executable) content itself. Message content I took from Fiddler. 
They were identical, no any encoding.

I created a multi-part message, attached an executable (FRead(Attachment)) 
and
sent (LoadFromURL, method POST) it to a php script  and compared received 
one with original. It worked. But I tested only on my local system.

Regards,
Vladimir

Yes, that works too. The way it is done is through the boundary markers,
which delimit the start and end of a part. I made a mistake in suggesting
base64 - this is used in 7-bit transportation systems (such as SMTP) to
cater for 'illegal' characters.

My apologies.
