Hi.
I have problems with the ListBox control, (class CListBox), 'cause I have a Access 2000 database with text in russian. When I show the data in an EditBox or even in a Button, everything work fine, but when I want to show the data in a ListBox, it shows something like "??????????" or "|||||||".
The listbox have not UNICODE support?.
I think that the problem is with the method AddString() maybe it convert the text to ANSI.
What is the solution?. There's is an alternative listbox?
Thank you.
Demian.

Send a message to the ListBox directly and use
SendMessageW. Then it will interpret LPARAM/WPARAM
as unicode parameters.

Hi!
Thank you for your answer.
I have write something like that
<br />
::SendMessage(m_lstText.GetSafeHwnd(), LB_ADDSTRING, 0, (LPARAM)(LPCTSTR) field);
And I have the same problem, the listbox can't show the info.
field is a CString variable, that one line before is asigned to an editbox that shows well the text in russian. At the beginning of the procedure the variable field was filled with the field of the database.
I dont know what I doing wrong.
Thank you very much for your support.
Demian.

Hi Demian,
Do you compile your app with UNICODE support?
If no, then you cannot use CString because it will
internally use ANSI characters.

Yes the application is support UNICODE.
Remember that I can see the data in the editbox.

I compiled a small sample app.
And RChin got the trick right from the beginning.
The font is the problem.
A ListBox uses the MS Sans Serif font, which obviously does not support Unicode.
Set the font to a different type, the it will work, like the following MFC sample code:
<br />
<br />
CFont *pFont = m_ctrlList.GetFont();<br />
LOGFONT lf = {0};<br />
pFont->GetLogFont( &lf );<br />
::lstrcpyn( lf.lfFaceName, _T("Tahoma"), sizeof( lf.lfFaceName ) / sizeof( lf.lfFaceName[ 0 ] ) );<br />
<br />
m_font.CreateFontIndirect( &lf );<br />
m_ctrlList.SetFont( &m_font );<br />
<br />
That should do the trick...

In addition to the comment above^, ensure that the font used by the listbox for display supports your russian UNICODE characters.

hello every body
what is the future of vc
ive read that microsoft wants everybody to move over to managed code
what is managed code
is this the end of vc
joooooooe
|
|
|
|
|
is it because code is going to be managed that VC is going to stop ? never !
second thing, every thing can't be managed... watch this

Oh, I think VC will still be around. But to take advantage of newer OS features, probablly you'll have to use Managed C++ or some other .NET language. MFC, in my opinion, is headed towards maintenance mode. It will probably always work and compile, but I don't expect, say, all the new Longhorn stuff to be wrapped in MFC.
Unmanaged code will still be necessary, but it will be mostly for specialized functions and for backwards compatibility.
All that "managed" code is, is code that runs within the CLR framework. It is garbage-collected, can access the .NET runtime, etc.

While you speak, developpers are using C/C++ .NET and even assembly

I agree with navin's comment regarding MFC.
I have used, am using and will use the MFC for a long while to come, but I can see a point in the distant future where it may fall out of popularity with the programming masses as new development fads takes over.
Regarding VC++, I don't think you have anything to worry about. As far as I'm concerned, VC++ will always be around (OK, maybe not always, but for a loooong time). The libraries in use may vary from MFC, ATL, WTL or the .NET malarky, but the language itself will survive. Vive VC++!

I can't imagine coding without using the VS environment, so I guess I was specifically talking about VC++.

Yes I admit it. I am a programming spawn of the Microsoft generation.
I did try tinkering with the Mandrake version of Linux a few years ago, but it scared me so much that I have not touched it since.
Don't get me wrong though, I have no dislike either way, its just that all my time right now involves development and continual learning of Microsoft products.

I am making a Win32 project in VC++ v7. When I click on the executable, I want it to run in the task bar. How would I do this? Any help is appreciated.

Hi All
I am a fresher in C/C++, I want to read first 2 bytes from a BMP image, when i open the file in "rb" and use scanf to read first 2 bytes, I am unable to read. Can i know the reason.
Thnx in advance
regards

Off the top of my head,
scanf reads from stdin (e.g. Keyboard on a console
sscanf processes a given string.
fscanf reads from a FILE.
So you are probably using the wrong one!

Since i have two read two bytes from the file I have to use
fscanf

fscanf... The mysterious function 
If you just want to read 2 bytes I wouldn't use the fscanf function, just use the fread function:
BYTE bytes[2];<br />
fread(bytes, 1, 2, fileptr);
If you insist on using the fscanf function:
BYTE bytes[2];<br />
fscanf(fileptr, "%c%c", &bytes[0], &bytes[1]);
Best regards,
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Hi Reichi
Thnx for u'r solution, Actually i used fread to solve the problem but i was interested to know on what occasions do we use fscanf,one occasion as of i know is when u write a file and read it in the same order as u write. Is this the only occasions we use fscanf or is there any other use.
I thought fread takes more memory cycles so thought of using fscanf. So I went inside the fscanf function but could not make out it works, Now i found a solution i need not know
Thanx a lot for u'r help.
Regards
