error in Richedit [bug in FWH]

[Antonio Linares]

John,

In a dialog you have to press CRLF (enter) before the style change.

I have tried to dynamically modify the RTF but without success

[ukservice]

Antonio,

Thanks for reply, but this way is unusable. It should work as Word.

Is it possible to fix it?.

Thanks so much,

[ukservice]

Antonio,

It worked fine with FW 11.03.

What happened before?.

Please, I need a fix urgent.

Thank you.

John,

We have not modified Class TRichEdit neither its C functions lately:

[Antonio Linares]

John,

If it was working fine in FWH 11.03 that means 30 x 9 = 270 days aprox.

Maybe my changes for:

* Adapting internal\richedit.c to 64 bits (232 days ago)

made the difference.

Are you using Borland ?

[ukservice]

Antonio,

Yes, I use BORLAND 5.82.

Thanks.

[ukservice]

Also, in FW 11.03 I used Harbour 2.x provided by Fivetech (with the installer).

[Antonio Linares]

John,

The changes that I did only affected Microsoft code, not Borland.

So if it was working fine in 11.03 and now it is not, then it may be the side effect of another change. That will make it harder to locate it to provide a quick fix.

Can't you use a window instead of a dialog ? That would solve it for now...

[ukservice]

Antonio,

Thanks, but I can´t use a Window. The Richedit must be in the dialog (in fact, it´s a Folder with several Pages).

The point is why FW 11.11 select all text when issuing a oRtf:Refresh().

Antonio, John,

TRichEdit inherits from TControl and TWindow, maybe there has been made some changes since 11.03 causing that behavior.

You could compare the sources to find out what happened.

Just an idea ...

[Antonio Linares]

Stephan,

We are going to check from version 11.03 to see what may have caused the difference

[Antonio Linares]

Stephan, John,

We have been doing some more tests with the RichEdit control and found that there are different behaviors on it when using it on a window or on a dialog. The tests I have done use pure C language (no Harbour, no FWH).

I plan to publish the tests here for your review, thanks

I plan to publish the tests here for your review, thanks

Ok

Hi everyone;

If I follow the discussion correctly, then I confirm that I've observed this Trichedit unwanted behavior. The problem can be reproduced with \samples\testrich.prg. Simply change line #32 to this:

Code: Select all | Expand

   REDEFINE BUTTON ID 998 ACTION ( oRich:SetBold( .t. ) /*oRich:GoToLine( 10 )*/, oRich:SetFocus() )
 

Highlight some text and then press the last button (#998). The selected text is set to bold, but immediately after that, all text gets selected (select all).

I did a diff on TRichEdi and could not find any differences dating way back. I think the culprit is TControl. There is a newer method PaintBack() that loos very conspicuous.
