Dragon Naturally Speaking 9.5

Kern · Post by **Kern** » Wed Dec 12, 2007 7:54 pm

We would like to use Dragon Naturally Speaking to dictate text into TRichView-Components (Ver. 1.9.24) .

We changed some entries in nsapps.ini (Dragon) like
TDBRichViewEdit=4. This entry tells the Dragon software that this field is a Richtext-Field. We made the same entry for TDBMemo which is working all right. Working means, that the field is recognized from the Dragon software as a standard-window.

TDBMemo uses standard edit control, so external applications must know how to get text from it. But TDBRichViewEdit is not a standard richedit control, so probably it will not work.
It depends on how this software gets text from control. It may use window messages. If it uses WM_GETTEXT, it will not work (this message is supported only if you use Delphi 7 or older; in new versions of Delphi, support for this message is disabled because it conflicts with VCL implementation). If it uses EM_GETTEXTRANGE, it may work.

Hi Sergey

We found some news about the Dragon implementation:

if you want to make your application Select-and-Say compatible with DNS 9, make sure that your application both supports MSAA and that all Windows that support dictation use Text Services Framework.

So there would be a chance to implement TRichView if it uses MSAA? How can we do that?

Post by **Sergey Tkachenko** » Wed Jan 16, 2008 6:01 pm

I never worked with MSAA. It looks like it requires implementation of IAccessible and may be a couple more interfaces.
Please remind me again after release of next TRichView update (v10.0), planned for February.

I know this is an old post but did you have a chance to add the required implementation to TRichViewEdit ? Someone just told me that Dragon Natural Speaking didn't work with TRichViewEdit.

Thanks.

Sorry no, it is still do not implemented.
And I do not have an up-to-date information about features to implement in TRichViewEdit to support DNS; and I cannot even test it because they do not offer trial versions.

Too bad

Hello,

it's possible to tells Dragon that TRichViewEdit is compatible in nsapps.ini

Code: Select all

[.Global\Global Enable Class Names]
RICHEDIT=2
RichEdit20A=3
RichEdit20W=4
RichEdit20WPT=4
RichEdit50W=4
RichEdit60W=4
Edit=1
TEdit=1
TMemo=1
REComboBox20W=1
TRichEdit=2
RichTextWndClass=2
TRichViewEdit=1

but then TRichViewEdit needs to support more EM_xx messages

for now, my test do not work but here is my code

the messages are not the same according to the value set in the ini

The new version of TRIchView supports the following edit/richedit messages:
EM_GETSEL, EM_SETSEL, EM_GETTEXTRANGE, EM_LINEFROMCHAR, EM_EXLINEFROMCHAR, EM_LINELENGTH, EM_LINEINDEX, WM_GETTEXTLENGTH, WM_GETTEXT, WM_SETTEXT.
There is one important thing that I was not able to find in Windows documentation, but found by experiments: how many characters are in line breaks?
As I found, in WM_* messages above, line breaks are counted as 2 characters both in Edit and RichEdit.
But for EM_* messages, there is a difference: line breaks are counted as 2 characters in Edit, but as 1 character in RichEdit.

TRichView uses 2 characters per line break in these events, so it makes sense to introduce it as an Edit, not as a RichEdit. Because of this, messages specific for RichEdits become unnecessary.

with last version of RVEditDemo.exe, if I set TRichViewEdit=1 (3 or 4), I have a access violation error at 0040712C
I guess it's about EM_POSFROMCHAR when Msg.WParam is not a Pointer to a TPointL structure but a 0 based char index.

If I set TRichViewEdit=2, and I ask Dragon to set text in bold, I have a very strange error with a dialogbox.
the title is "dd10edit"
and the french text talk about COM error HOOKERR_CANNOTINJECT

Post by **Sergey Tkachenko** » Thu Jun 03, 2021 11:53 am

EM_POSFROMCHAR is not processed by TRichView at all, so probably the error is in another message.
Unfortunately, I do not have DNS to check.

Hello,

I'm still playing with the Dragon

to implement EM_POSTFROMCHAR I need to return the pixel position of the nth character for the text

I've made a quick test with TMemo with a the text "test"

Code: Select all

EM_POSFROMCHAR -1, 0 returns $FFFFFFFF
EM_POSFROMCHAR  0, 0 returns MakeLong(1, 4)
EM_POSFROMCHAR  1, 0 returns MakeLong(1, 10)
EM_POSFROMCHAR  2, 0 returns MakeLong(1, 16)
EM_POSFROMCHAR  3, 0 returns MakeLong(1, 22)
EM_POSFROMCHAR  4, 0 returns $FFFFFFFF

I guess I could use LinearToRichView and Item2DrawItem but I don't see how to get individual character position.

Thanks

for information, here a the notable message when Dragon add a text "test" in a TMemo, select the text and make it bold (Ctrl+G with the french term "Gras")

Hello,

Finally I got it working

1) add TRichViewEdit=1 in nsapps.ini
2) handle this messages

For Dragon Medical One, you have to use the Standalone version and change SOD.exe.Config to add a TextControlMappings section inside ApplicationSettings to map TRichViewEdit to a TMemo

Code: Select all

<applicationSettings>
...
   <TextControlMappings>
    <TextControlMapping Control="TMemo">
      <WindowClass>TRichViewEdit</WindowClass>
    </TextControlMapping>
  </TextControlMappings>    
 </applicationSettings>

damned ! the flickering is back :/ since I've updated to last version of RV (from an old version)

I have to dig into the methods...

when Dragon Medical One is active I have this messages permanently

Code: Select all

procedure TRichViewEdit.WndProc(var Msg: TMessage);
begin

Sergey, have you any idea of what can produce a move/paint in that messages ?

hum...it seems that LinearToRichView is the source of the pb
