RichTextBox, Emdash differences in Windows 2000

[Mike]

Hi,

 

Does anyone know of documented differences using the Microsoft Rich Textbox Control 6.0 (SP4) (RICHTX32.OCX  V.6.00.8804) under WinNT 4 and Windows 2000?

 

Created an RTF file containing both an emdash and endash. Created an identical VB app with VB6 with NT4 and Win2000. The app is simply a form with a RichTextBox which loads the RTF file.

 

Under NT4, the RichTextBox properly displays the  emdash and endash,. Under Windows 2000, the emdash and endash are displayed as hyphens.

 

If I set a breakpoint and display the .TextRTF property of the RichTextBox, NT4 shows (in part):

 

\par Here is the EMDASH\emdash EMDASH
\par
\par Here is the ENDASH\endash ENDASH

 

while the same breakpoint in  Win2000 shows:

 

\par Here is the EMDASH-EMDASH
\par
\par Here is the ENDASH-ENDASH

 

[in the RTF file, the actual emdash and endash characters appear between the upercased words.]

 

So it seems that before the RichTextbox Control even "sees" these characters, they are being transformed to hyphens - perhaps by riched20.dll?

 

The versions of riched20.dll are 5.30.23.1200 (Version 3) under NT4 and 5.30.23.1209 (Version 3) under Win2000.

 

Thanks,

Mike
