Desaströse Performance von TRichedit

Zitat von Kas Ob.:

What about this

And this is supposed to work in a Delphi since 2009?

SendMessage = SendMessageW = Unicode
Is your file also Unicode?

It should !

Notice by sending the stream in full as it in the file, meaning the header included U+FEFF BOM header, yet the Window class recognized it, and handle it right, this even should work with Delphi 5.

But was it faster ?

At least the example files posted above are.

Anyway, the TMemoryStream approach is quite similar to setting the Text or SelText with a string. It doesn't affect the performance, though.

Yes after re-reading more, i think WM_SETTEXT with Delphi 5 or may be even Delphi 7 might not work, as it will fail to handle the BOM marker for UTF16, as the used RichEdit class is version 1.0 and it is

Zitat:

ANSI (single-byte character set (SBCS) and multibyte character set (MBCS)) editing

So will work if the class changed to version 2.0, yet i might be wrong though, all in all this need more digging.
