Open/read Unicode file contents and display

[Bert Slootmans]

I need to be able to open a text file with Unicode content (Chinese characters and Pinyin).

Using the following code I am able to read the first Chinese character correctly, but NOT the following Pinyin. The next character is read, but is again incorrect. Only plain Asci characters are loaded corectly.

SUB LoadCharacters ()
   DIM strTempChar AS STRING
   DIM strTemp AS STRING
   DIM strTempMeaning AS STRING
   OPEN "data\Chinese.dat" FOR INPUT AS 1
   WHILE ISFALSE EOF(1)  ' check if at end of file
      LINE INPUT #1, strtempchar
      strtemp = PARSE$(strtempchar,1)
      UniMsgBox BYVAL 0, STRPTR(strtemp), 1, BYVAL 0
      strtempmeaning = fixtextline(PARSE$(strtempchar,2))
 
      MSGBOX strtempmeaning
 
      intcounter = intcounter + 1
      REDIM PRESERVE strCharacter(intcounter)
      REDIM PRESERVE strMeaning(intcounter)
      strCharacter(intcounter) = strtempchar
      strMeaning(intcounter) = strtempmeaning
 
   WEND
   CLOSE 1
END SUB

How can I fix this? and how can I display this Unicode on a PBWin label control (I don't want to use the richtextbox because everything needs to stay read-only)?

A disabled richedit does not seem to appear with gray colors.

DDT does not support Unicode. You'll have to use SDK-style coding. Here's a demo to get you started:Directory List with Non-ASCII (Unicode) characters in file names 5-31-08

(There are some other demos of this, as this subject has come up numerous times).

If you only have one or two controls which must support unicode on the screen, you might (that means I've never tried it) be able to use DDT syntax to create the controls, but you'll have to owner-draw them ... which owner-drawing will require SDK-style commands.

FWIW, a regular edit (class "edit") control offers the style ES_READONLY, but if you are creating Unicode controls anyway you may as well stick with the label ("static") control.

RichEdit control used as a label can display Unicode (Chinese etc) characters.
They can be made to look like a label easily enough..

Just FYI...

OPEN "data\Chinese.dat" FOR INPUT AS 1
   WHILE ISFALSE EOF(1)  ' check if at end of file
      LINE INPUT #1, strtempchar

Using the LINE INPUT# or PARSE statements, or any of the functions designed for use with "text" pretty much assumes that text is "regular ASCII" and you "may" have some problems with Unicode.

Eg, LINE INPUT # is documented to read from the current file position up the next CRLF or end of file; but CRLF is NOT CHR$(13,10) in a Unicode file. (In Real Life LINE INPUT does not work this way, it never has; but maybe someday the behavior will match the documentation). (It actually reads up to CR, not CRLF).

It might be better us open the file for BINARY access and handle the parsing a little differently.

Took me a while to figure out how to parse the string but this works fine now.

Also the code referenced in the next quote works perfect.

All I need to know now is how I can change the font of this Unicode control.

I've tried this:

  IF hCtl THEN
     ' Either use parent font or Windows' GUI font...
     LOCAL hFont AS DWORD
     hFont = SendMessage(hParent, %WM_GETFONT, 0, 0)
'     IF (hFont = %NULL) THEN hFont = GetStockObject(%DEFAULT_GUI_FONT) ' Original code, changed with next line:
     FONT NEW "Arial Unicode MS", 288, 0 TO hfont
     SendMessage hCtl, %WM_SETFONT, hFont, %TRUE
     FUNCTION = hCtl
  END IF

But that doesn't do much (only changes the font to BOLD).

Any idea?

[Michael Mattias]

In the example I gave you the link to, there is an example of changing the font.

Try creating your font with CreateFont as shown in demo instead of FONT NEW and see what happens.

Bert,

Have a look at the sample I posted in that thread (#16) http://www.powerbasic.com/support/pb...0&postcount=16

That shows a couple of ways to set the font in the Unicode controls created with a variation on Kev's method.
