ReplaceSel(…) does not work with DBCS

[John R Shaw]

I am trying to display Japanese characters in a CRichEditView by setting the text using GetRichEditCtrl().ReplaceSel(…), but it does not work. The correct font is selected, so I know that is not the problem. DBCS Example: 1) I run the Rich Text (RT) application, written in VC6. 2) Open ‘Accessories->System Tools->Character Map’, select same Font and Language as RT app., select full-width character ‘Z’ and paste it to RT app. 3) No problem! 4) Inside the RT app., programmatically select the DB text, and get a copy of it using GetRichEditCtrl().GetSelText(). 5) Replace the selected text with the copy you just made using GetRichEditCtrl().ReplaceSel(…). 6) Problem: Instead of displaying a DB character it displays the ‘lead’ and ‘trail’ bytes as individual characters. The full-width ‘Z’ is stored as “\x82\x79”, but if you pass that string to ReplaceSel(…), it will display “,y” instead of “Z”. I have verified that the correct font is specified for the text being displayed (SHIFTJIS_CHARSET, "MS PMincho"), but it is not showing correctly, as stated above. Do you have any ideas why this happens?
