Richedit5 and XP

[Natter]

I have several clients on computers which costs XP. I wrote an application using richedit5. On W10 everything is normal. Under XP (if richedit5 there are several Windows) when you exit I get the error. If you use the old richedit, then everything is fine

Yes, MsftEdit.dll is used for control RichEdit5, and not exist in XP ( I think with XP SP1 or later exist it, but I'm not sure and this control I not tested in XP )
RichEdit use RichEd20.dll
But if you copy MsftEdit.dll in folder of application it's possible run ok

Thanks, Cristóbal ! I understood. And how can you insert a square root or a degree or other Unicode characters into richedit ?

[cnavarro]

Excuse me, I do not understand your question well
1.- What language are you using?
2.- Do not confuse "unicode" with special symbols (which may depend on the font used), or with ascii symbols that you can obtain by pressing ALT + 167, for example.

You can easily verify that the control accepts any character you wish to put, using the Windows utility charmap.exe

In Microsoft Word there is an option Insert -> Symbol. Is it possible to do it by means of Richedit ?

[cnavarro]

Not exactly, although CharMap is very similar
