Jeffrey, you certainly choose the hardest topics for your first PB/DLL program!

Assuming you are using DDT, you can use a CONTROL ADD "RICHEDIT" statament, but you have to explicitly load the RICHED32.DLL library using LoadLibrary(). See the PBNOTE.BAS example file for the necessary code to load the library, etc.

If all you wish to to is display STOP in red/black, then there are other ways... for example, use an IMAGE control with a BMP with the word STOP on it, etc. Yet another way (a bit complicated) is to create an static control (LABEL) and specify a custom font of the appropriate size, then intercept the
%WM_CTLCOLORSTATIC message and set the foreground & background colors - I seem to remember that you may have already experimented with code along these lines?

Lance, I don't think that PBNOTE program uses RichTextBox control. I looked through the code, WIN32API.INC, and RICHEDIT.INC files but they were not helpful. I found a sample program that used RichTextBox control in a message posted on this forum and used it. I think that using

Code:

and

in messages remove CR/LF characters from text but I am not sure. Jeffrey.

Not sure this is what you are looking for, but I've just posted a
small sample in the Source code section that shows how to create
and fill a Richedit control with text, search for all occurrences
of a certain word and then mark them all with a new color.

It loads the text "Start and Stop", where "Stop" then can be marked
with red (since that's the word you were asking for).

Who knows, maybe you can find something useful in it..

**Lance Edmonds** · 23 Apr 2000, 09:11 PM

The PBNOTE.BAS example I have here uses a RICHEDIT control, but it seems that the most recent version of this file (as supplied with PB/DLL 6.0) uses a standard EDIT control instead. Sorry for the misinformation.

There have been quite a few threads in this BBS about using RichEdit controls, so you should find a few useful code snippets.

Borje, Thank you very much for the sample code. I modified the code for my subway stop program but I want "Stop" and "Change" to be printed in red and "Skip" to be printed in green. Here is the code:

Why not lift out the actual color marking to a separate sub, like:

Code:

'¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤
' Loop through string, pick out positions, select occurrences and then paint
' Note - Instr returns pos +1 in relation to Selstart, so we have to use -1
'¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤
SUB MarkString(BYVAL AllText AS STRING, BYVAL MyText AS STRING, BYVAL cCol AS LONG)
   LOCAL stopPos AS LONG
 
   stopPos = INSTR(AllText, myText)
   DO WHILE stopPos
      CALL SendMessage(hEdit, %EM_SETSEL, stopPos - 1, stopPos + LEN(myText) - 1)
      CALL setRichTextColor(cCol)
      stopPos = INSTR(stopPos + LEN(myText) - 1, AllText, myText)
   LOOP
END SUB
 
'¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤

While "Stop" and "Skip" are four-letter words, "Change" is six-letter word. The "Chan" is printed in red and the "ge" is printed in black. I want "Change" to be printed in red. Jeffrey.

------------------

**Borje Hagsten** · 26 Apr 2000, 03:32 PM

Change

call sendmessage(hedit,%em_setsel,stoppos+4,stoppos+len(alltext))

to

call sendmessage(hedit,%em_setsel,stoppos+len(mytext)-1,stoppos+len(alltext))

------------------

**Jeffrey Morris** · 27 Apr 2000, 12:47 PM

Borje, I changed the SendMessage code but the "Change" word is still printed in red and black, not red only. Jeffrey.

------------------

**Borje Hagsten** · 27 Apr 2000, 02:40 PM

You don't check to see if Instr actually finds something to mark,
so the function marks everything, which means the last word you
send to it, "Skip" will set the final looks of things.
The following should work:

Code:

SUB markstring(BYVAL alltext AS STRING,BYVAL mytext AS STRING,BYVAL ccol AS LONG)
  LOCAL stoppos AS LONG
  stoppos=INSTR(alltext,mytext)
  IF stoppos THEN  'must check to see if something actually was found!!!
     CALL sendmessage(hedit,%em_setsel,stoppos-1,stoppos+LEN(mytext) - 1)
     CALL setrichtextcolor(ccol)
     CALL sendmessage(hedit,%em_setsel,stoppos+LEN(mytext)-1,stoppos+LEN(alltext)-1)
     CALL setrichtextcolor(0)
  END IF
END SUB

**Jules Marchildon** · 27 Apr 2000, 02:54 PM

Borje, I have followed your RichText posts. I would like to
thank you as well, as this helps me too.

BTW, I tried Jeffrey's code and it works the way he is asking.

Regards, Jules

**Borje Hagsten** · 28 Apr 2000, 12:17 AM

Glad to hear you find it useful Jules, especially since I've
learned so much from *you* in these forums over the years..

I actually don't use the Richedit control that much myself, but I'll
see if I can wrap up a more complete sample for it this weekend for
the source code section. It seems to be some need for one..

------------------

**Jeffrey Morris** · 28 Apr 2000, 01:37 PM

Borje, I got the subway stop program (short version) working properly. I edited the long version and got it working properly. Jeffrey.
