Take a look at http://www.fileformat.info/info/unicode/char/2014/index.htm to see if the information there helps you out (em dash character's unicode value is 2014).

 

by: KenTan85Posted on 2009-08-27 at 06:21:24ID: 25197763

Hi irudyk,
The symbol is not a em dash. From I gathered it seem to be a unicode of "F0BE" which I cannot seem to be able to detect in word 2007.

 

by: irudykPosted on 2009-08-27 at 06:32:26ID: 25197888

Hmm, okay, well from http://www.fileformat.info/info/unicode/char/f0be/index.htm</A> it would appear that what you are looking for is not a valid unicode character.  So, I'd say the answer to the question you posted is that you won't be able to detect this character by unicode.

 

by: irudykPosted on 2009-08-27 at 06:33:33ID: 25197903

Seems like the link I posted got messed up - try http://www.fileformat.info/info/unicode/char/f0be/index.htm

 

by: KenTan85Posted on 2009-08-27 at 06:39:24ID: 25197968

Orh? So does that mean I cannot detect this in word 2007? If u refer to my screenshot, it seem to be a Symbol font unicode stuff,,, What does it mean...?

 

by: irudykPosted on 2009-08-27 at 09:02:33ID: 25199764

Well, when you are actually in Word you can find this symbol character via VBA code by finding the text defined as ChrW(61630).  So in Word VBA you would do something like:

Selection.Range.FInd.Execute(ChrW(61630))

which return True or Flase depending on whether the symbol character is found

In VSTO, you could try using the Word application object (e.g. if defined as objWordApp) and try

objWordApp.ActiveDocument.ActiveWindow.Selection.Range.Find.Execute(ChrW(61630))

Now when I tried it, I get False even though the symbol is in my document, so this is not likely an option for you (unless I missed something).

 

by: KenTan85Posted on 2009-08-27 at 18:39:58ID: 25204393

irudyk: yes you are correct... I also tried this at my side and I still cannot detect it.

Since it can input into word, I believe there is a way to detect this, just that we do not know how.

 

by: irudykPosted on 2009-08-31 at 08:49:48ID: 25223755

Okay, well you could try the following to see if the character is found (a message box will pop up with the result).  Again, the code example uses the Word application object (e.g. defined as objWordApp) 

Dim objWordApp As Word.Application
objWordApp = WordAddIn1.Globals.ThisAddIn.Application
With objWordApp.ActiveDocument.ActiveWindow.Selection.Find
    .ClearFormatting()
    .Text = ChrW(61630)
    .Replacement.Text = ""
    .Forward = True
    .Wrap = Word.WdFindWrap.wdFindContinue 'or .Wrap = 1
    .Format = False
    .MatchCase = False
    .MatchWholeWord = False
    .MatchByte = False
    .MatchWildcards = False
    .MatchSoundsLike = False
    .MatchAllWordForms = False
    MsgBox(.Execute)
End With

Just curious if you had success with the above code? Using it, I was able to locate the symbol.  Seems strange though that I had to write the code the way I did in order to find the symbol as opposed to executing the find in one line of code which as we found out did not work.
