hi,

while german Xbase++ Forum have installed new "phpBB" Ver. 3
the "Subject" with SEE32 have change.

*** snip ***
Subject:

Subject shoud be encode to : "Xbase-Forum: Neue Software, Forentreffen im 
Frhjahr 2009"

not shure where to start ... i have search Newsgroup and did found
somethings with MultiByteToWideChar and WideCharToMultiByte
and some Tip to use Pablo Botella ot4xb LIB ...

This means that the Subject line was Base64 encoded, because of the "ü" in 
the text was represented as an UTF-8 character. To convert it back, use a 
routine to "decode" Base64 encoded text, like "FromBase64()" from ASINet 
or "XbBase64Decode()" from Xb2Net.

First, you need to take both of the strings between the "?B?" and the "?=", 
and combine them, then decode that string, and because the "ü" is UTF-8 
encoded, you need to use OT4Xb's "cUtf8ToAnsi()" function to convert the 
resulting string to ANSI -- or use "cUtf8ToOEM()" for OEM.

If a subject line starts with "=?ISO-8859-1?" (or something similar) 
instead of "=?UTF-8?", you won't need the cUtf8ToAnsi() function. The 
character set description isn't case sensitive, so it could also be 
"=?utf-8?" or "=?iso-8859-2?" etc. If a subject line continues with 
"?Q?" instead of "?B?", you need to use "FromQP()" from ASINet (or a 
homegrown function) instead of FromBase64()"/"XbBase64Decode()".

Because that particular Subject line is longer than 75 characters, it was 
encoded in two parts that you need to combine. Longer text might even be 
split into three or four lines. The basic format for "encoded words is 
this: "=?" + Character-Set + "?" + Encoding + "?" + Encoded-Text + "?="

Hi Jimmy,

 >> routine to "decode" Base64 encoded text, like "FromBase64()"
 >> from ASINet or "XbBase64Decode()" from Xb2Net.

does SEE offer the needed function or did you get a different one ?

I have got a implementation in PowerBasic, build with the inline 
assembler. No chance to understand for me 
I thought I red on there homepage somthing about decode Base64.

Hi,
See a running test 
http://news.xbwin.com/ot4xb.public/164/attachments/0/atlenc.zip

Just need to add the #include "atlenc.ch" and put the atlenc.dll in your app directory

local cBase64 := "QmVuYWNocmljaHRpZ3VuZyDDvGJlciBuZXVlIEFudHdvcnQg4oCUIOKAnk5ldWUg" +;
                 "Rm9yZW5zb2Z0d2FyZeKAnA=="

? cUtf8ToOem( cBase64Decode(cBase64) )   

function cBase64Decode( cSrc )
local nSrcLen := Len( cSrc )
local nDstLen := Base64DecodeGetRequiredLength(nSrcLen)
local cDst    := ChrR(0,nDstLen)
if Base64Decode(cSrc,nSrcLen,@cDst,@nDstLen)
   return Left(cDst,nDstLen)
end
return NIL
