more info about it : 

  1- lets say we got a code comment in vb6 and its a long one so i need to seperate with using ( _) like;
     'Blablabla bla situation is needed to handled by blablabla situation _ 
      and another blablablabla so we can blablablabla bla and blablablabla _ 
      in the end bla bla blabla.

so this whole text should be rendered as grey but sadly its not. 

After using (') u should be able to check it as string in that line by trimming 
and getting the last 2 chars in that string.
If its ( _) space and underline than use that lines style at the next line too 
or you can look for just last 2 chars if there is a (space + continues sign) 
than u should give the same styling to the next line, but offcourse i'm just 
thinking in vb6 mind.. it may be a little harder or easier in js code or with 
jquery coding also similar problems occur with the C# u might have noticed 
about it.

Just please do something about these continues signs.. Thanks already.

This is definitely not a published feature of the VB.net grammar and I can't 
find a VB6 grammar, but it seems unlikely to cause confusion so I fixed it at 
http://code.google.com/p/google-code-prettify/source/detail?r=203#

For the record, the relevant portions of the VB.net grammar are quoted below:

According to http://msdn.microsoft.com/en-us/library/aa711643(v=vs.71).aspx

Comment ::= CommentMarker [ Character+ ]
CommentMarker ::= SingleQuoteCharacter | REM
SingleQuoteCharacter ::=
   ' |
   < Unicode left single-quote character (0x2018) |
   < Unicode right single-quote character (0x2019)

and according to http://msdn.microsoft.com/en-us/library/aa711639(v=vs.71).aspx

Character ::= < any Unicode character except a LineTerminator >

so the _ line continuation syntax does not appear to be a publish syntactic 
feature of VB.net.

Thanks so much about this. Its a VB6 feature and it may have joined the
usual VB6 syntax with any update.
