qwert Posted July 12, 2014 Share Posted July 12, 2014 I'm having difficulties with the GUIRichEdit.au3 UDF It seems to have gone through some evolutionary changes over the years and at least a couple of the streaming functions have problems. I've entered a bug report on ToFile. But others, I just can't follow. For example, can someone experienced with these functions shed light on the meaning of this statement: Local $iWparam = ($s == "{rtf" Or $s == "{urtf") ? $SF_RTF : $SF_TEXT It's in Func _GUICtrlRichEdit_StreamFromVar($hWnd, $sVar) Usually, when I encounter a question mark character, it means that something couldn't be interpreted ... like a character from another character set. But I see several uses of question marks in StringRegExp, so maybe the above use has meaning. But, I've never typed one in, myself. Also, is an original copy of the UDF available for inspection? ... a copy from before it was added to Include? Thanks for any help. Link to comment Share on other sites More sharing options...
BrewManNH Posted July 12, 2014 Share Posted July 12, 2014 (edited) Local $iWparam = ($s == "{\rtf" Or $s == "{urtf") ? $SF_RTF : $SF_TEXT That's a statement using the ternary operator that's in the newest versions of AutoIt. It's a shortened version of an If/Then/Else statement. What that statement is saying is if $s is equal to "{rtf" or $s is equal to "{urtf" then $iWparam will be assigned the value of $SF_RTF, if neither of those comparisons are true then $iWparam will be assigned the value of $SF_TEXT, and it's a case sensitive string comparison. NOTE: I don't know if you'll be able to find a pre-include version of the RichEdit UDF, but you can certainly find earlier versions of it in the archived versions of AutoIt. Just find when it was added to the standard UDFs and find that version in the archives.

qwert Posted July 12, 2014 Author Share Posted July 12, 2014 Thanks, BrewManNH. It now makes sense. I guess the time to debate 'ternaries' has passed ... but it's sad to see the cryptic quality they inject into what is otherwise a refreshingly forthright and readable language. Anyway, the problem I'm chasing appears to be related to the EM_STREAMIN message calls. I'm streaming rich content from a variable and I'm getting a "transformed" result ... the biggest problem of which is the insertion of an unwanted/unneeded font, MS Shell Dlg. I've attached an example, if anyone happens to have ideas. I'm testing alternative methods. mLipok 1 Link to comment Share on other sites More sharing options...
Moderators Melba23 Posted July 12, 2014 Moderators Share Posted July 12, 2014 qwert, I guess the time to debate 'ternaries' has passedYup! the cryptic quality they injectOnly if you have never seen them before - once you understand the ternary syntax [i.e. (test) ? (true) : (false) ] is it any different to using other operators? I suggest <> and /= are also pretty cryptic the first time you come across them. a refreshingly forthright and readable languageAt least we agree on something!

qwert Posted July 12, 2014 Author Share Posted July 12, 2014 I suppose. I must have skipped that chapter in my CS courses. I think my aversion is due to the use of ? as an operator. [i.e. (test) ? (true) : (false) ] IMO, anything else ... like || ... or / ... would have been a better choice. '?' rattles too many neurons in the brain. But we make do with QWERTYUIOP keyboards and ASCII Control Codes, so maybe it's no worse. [shrug] Link to comment Share on other sites More sharing options...
BrewManNH Posted July 12, 2014 Share Posted July 12, 2014 The ? usage as the ternary operator is used in other languages and written the same way. It's just keeping AutoIt consistent with other languages so the learning curve wouldn't be steep.

Richard Robertson Posted July 14, 2014 Share Posted July 14, 2014 Yeah. Ternary is actually intuitive. Read it as question ? yes : no BrewManNH 1 Link to comment Share on other sites More sharing options...
