Hi to all (and merry christmas).
I am confused, have a mess into the head....

Well, I am trying show in a listview some special characters (like the spanish 'ñ'), but i have an unreadable result.

what are the steps for full support utf-8 format, in my program (edits, listviews, etc...)

thanks

Morlok

My program maintais a communication 'http' with a server in the net. This server replys in utf-8 format, and i want to show part of the message
in a listview (LVM_SETITEM), but some special characters are unreadables.

are ther some way to show them correctly.

(if i put the incoming message in a buffer and try
    invoke MessageBoxW, hWnd, addr Buffer, NULL,MB_OK  ----> i get Chinese characters  :shock: )

the goal is put the message in a listview, but i am lost.

thanks.

I think MultiByteToWideChar is what you need here

Hi, Morlok (hi, everyone)
My 1-st post and 1-st suggestion...you could use my funcs
to_UTF8 - which converts from UCS-2 to UTF-8
UTF8_to - which converts from UTF-8 to UCS-2
I actually didn't like Multi.. Wide.. APIs because of too large number of arguments. BTW I happily pass an input as UTF8 strings ussing these two in scintilla :)

UTF8_to endp

P.S. charachters greater than 0FFFFh are rarely used (maybe never) so I didn't bother implementing...

Create a 'Wide' listbox (CreateWindowExW).

Unicode Listview Revisited.... :roll:


Here is a small program that open a utf-8 file (only a few lines) and put the text into one Edit, one ListBox and at last one ListView.
(here i use the ramguru's func for trans utf-8 strings).

Well, the Edit and the ListBox display corretly the text, but no the listview.

	
    invoke UTF8_to, addr LocalBuff2, addr LocalBuff1	;THANKS ramguru FOR YOUR FUNCS (UTF8_to AND to_UTF8)

    invoke SendDlgItemMessageW, hWnd, IDC_EDT1, WM_SETTEXT, 0, addr LocalBuff1

    invoke SendDlgItemMessageW, hWnd, IDC_LST1, LB_INSERTSTRING, 0, addr LocalBuff1

    mov Item.imask,  LVIF_TEXT					
    mov Item.cchTextMax,256	 				
    lea edi, LocalBuff1
    mov Item.pszText,edi					 	
    mov Item.iSubItem,0				 		
    mov Item.iItem, 0
    invoke SendDlgItemMessageW, hWnd, IDC_LSV1, LVM_INSERTITEM, 0, addr Item

what is the ListView's trick for display unicode strings?

thanks
