Problem getting CHARFORMAT from Rich Edit, HELP!

[RyanCross]

Okay I'm trying to retrieve the CHARFORMAT of the Selected text of a Rich edit control but for someon reason the code I have won't fill in the CHARFORMAT type:

CASE %WM_NOTIFY
SELECT CASE CBWPARAM
CASE 105
nh = CBLPARAM
SELECT CASE @nh.code
CASE %EN_SELCHANGE
mask& = SendMessage(GetDlgItem(CBHNDL, 105), %EM_GETCHARFORMAT, 1, VARPTR(cf)))
END SELECT
END SELECT

mask& returns 0 no matter what and all other information returns 0 or "". So the CHARFORMAT type must not be getting filled in. Can anyone post an exnample or please tell me what I'm doing wrong.

a search of the bbs for "charformat" reveals the following thread that may interest you:

No that didn't help, unless I missed something. I can EM_SETCHARFORMAT perfectly fine, just getting CHARFORMAT is the problem.

If the UDT structure change did not fix your problem (I gather you read to the bottom of the thread?), then you will need to post compilable code so we can duplicate your problem.

Thanks!

It seems like RichEdit uses szFaceName + 2 bytes, so you need to
declare and use the following instead:

TYPE CHARFORMAT2
  cbSize AS LONG
  dwMask AS DWORD
  dwEffects AS DWORD
  yHeight AS LONG
  yOffset AS LONG '* > 0 for superscript, < 0 for subscript *
  crTextColor AS DWORD
  bCharSet AS BYTE
  bPitchAndFamily AS BYTE
  szFaceName AS ASCIIZ * %LF_FACESIZE + 2
END TYPE

Then you can use the following example to get the format for
selected text (taken from a rebuild of PBpad):

  LOCAL cf AS CHARFORMAT2
  CALL SendMessage(GetEdit, %EM_GETCHARFORMAT, _
                              %SCF_SELECTION, VARPTR(cf))

As discussed in the thread I noted above - you should not extend the ".szfacename" member by two bytes, but add an additional 2 byte dummy member to the end of the structure.

Yeah I added the dummy and removed the 2 extra bytes, but it still has no affect. Does anyone have any Richedit examples they could post? If not I'll try ot throw a small code together for an example of compilable code.

I'm not at my DEV PC to check if this is required, but I think you have to set the .cbSize member of the structure before calling the API.

I think it's time that we see your code...
