Even if we implement digest authentication in RVMedia code, we will be able to play only MJPEG by HTTP. RTSP and H.264 require FFmpeg or GStreamer (some time ago we started implementation of MJPEG by RTSP, but abandoned it).

You can disable word selection completely by assigning rvsmChar to RVStyle.SelectionMode. Unfortunately, you cannot disable it for Chinese text but enable for English text. But even with word selection, it is possible to select precisely: if you shrink the selection (while selecting, move the mouse ...

I added ADO+Access version of this demo. As I said above, the main difficulty was storing binary RVF data in a text (memo) field. I used the simplest possible binary-to-text encoding - hexadecimal code. It is simple and fast, but increases data size by 100%. A better alternative would be Base64 enco...

Nostradamus, this project was created in the old version of TRichView. The only required change to make it work in the new version of TRichView, is removing type-casting to Word in all calls of IsDelimiterW. For example, change rve.RVData.IsDelimiterW(Word(ws[Offs])) to rve.RVData.IsDelimiterW(ws[Of...

I'll try to make an example in the next couple of days. The main problem with MS Access, as far as I understand, the lack of field type for storing arbitrary binary data (required for RVF). Unfortunately, even "text mode" RVF is not really a plain text and requires a binary field. Well, there is a s...

If you want to change a cell background image, the code is similar. A direct assignment (cannot be undone): Table.Cells[0, 0].BackgroundImage := gr; Table.Cells[0, 0].BackgroundStyle := rvbsTiled; If you want to change as an editing operation (that can be undone), use SetCellBackgroundImage and SetC...

If you have a Table object, you can simply assign BackgroundImage property: Table.BackgroundImage := gr; This code copies an image from gr, you still need to free gr. However, if Table.BackgroundStyle = rvbsColor, this image will not be displayed. You need to assign rvbsStretched, rvbsTiled, or rvbs...

I suggest to place collapsible text in a table, and implement a link that hide/show a table (by assigning rvepHidden item property to 1 or 0). A similar feature is implemented in Help&Manual that uses TRichViewEdit as a topic editor. Here are examples of collapsible tables: https://www.trichview.com...

UI language does not affect spelling.
You can see the demos in ThirdParty\ASpell\Demos\
They change spelling language with this code:

Code: Select all

  RichViewEdit1.ClearLiveSpellingResults;
  RVASpell1.DictIndex := ComboBox1.ItemIndex;
  RichViewEdit1.StartLiveSpelling;

Can this be done in a TRichViewEdit by the end-user ? If so, how should it be done ?
Thanks.

Sorry, I do not understand the question. "Can be done" what?

You are right, this check must be added.

This is a bug. This code must be:

Code: Select all

    try
      // Open video file
      if not OpenFile(FormatContext, DecCurTime, filename) then
      begin
          FormatContext := nil;
          exit;
      end;
    except
      exit;
    end;

Unfortunately (unlike TRichView), ScaleRichView cannot add page breaks inside table cells. Page breaks can be only between rows.

There is no standard Clipboard format for Jpegs, so the copied image will be inserted as a bitmap. The only way to paste JPEG to RichViewEdit is copying a JPEG file (for example, from Explorer). Here is a function that pastes bitmap as JPEG: function PasteBitmapAsJpeg(rve: TCustomRichViewEdit): Bool...

Sorry, no. If you have RVF field, you have the following options to search: 1) Create one more field, a plain text. When saving RVF field, save a copy of document as a plain text in another field. Then you can use SQL queries or other standard tools to search in this plain text. or 2) Load content o...
