It's best to define both UNICODE and _UNICODE.

It might be easier to just use the macros defined in tchar.h like _tcscpy() and _tcslen().

Correct.

Did you assign a Unicode font to the edit control?

Sir,
I will tell you in sequence what happened. First I added 'UNICODE' ( in project-settings ). The app was unaware of unicode (displayed ???). I added _UNICODE and suddenly the compiler gave me a bitter error that _WinMain@16 is an unresolved external symbol. I had to give my entry, i.e. entry:"wWinMainCRTStartup". I really dont know why I had to do this, but after this only it compiled, and the program worked with unicode. I did not assign any unicode font also, to the edit control. What is the significance of this "wWinMainCRTStartup"? and is that if i assign a unicode font to the edit control it can still go ahead to be unicode aware without defining _UNICODE and my own entry point "wWinMaainblahblah"?
Thanks and Regards,
Aljechin Alexander

It's the entry point for Unicode MFC applications.

The best way to answer "What happens if..." questions is to just try it and see.

Is there a way to convert RTF string to plain text?
Putting a string into CRichEditCtrl using Callback StreamIn and then getting it out using CRichEditCtrl::GetWindowText seems overly complicated and doesn't work in my case, since GetWindowText returns null unless you've displayed the string (UpdateData(FALSE)) and it doesn't support unicode (or at least I've been unable to get it working).
Just stripping RTF codes wouln't do since unicode rtf uses some strange character encoding.
If you know how to do it I'd really appreciate. (I think I've read something about coping it into clipboard and then getting plain text, but can't find it..)

Copy it to the Clipboard then get the CF_TEXT(?) format and use that. Should work.

Every bit of code I found/wrote in order to put CStringW into clipboard caused program crash (no exception thrown).
.. help?

After you stream it into the Rich Edit control you can always stream it out.

For some reason it doesn't work.
I'm using this StreamIn/StreamOut:
<code>
static DWORD CALLBACK StreamOut( DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb )
{
// Setting up temp buffer
char* buff;
buff = new char[ cb + 1 ];
buff[ cb ] = ( char ) 0;
strncpy( buff, ( LPCSTR ) pbBuff, cb );
int max = strlen( buff );
CString* str = ( CString* ) dwCookie;
#ifdef _UNICODE
// We want to convert the buff to wide chars
int length = ::MultiByteToWideChar( CP_UTF8, 0, buff, max, NULL, 0 );
if( length )
{
TCHAR* wBuff = new TCHAR[ length ];
::MultiByteToWideChar( CP_UTF8, 0, buff, max, wBuff, length );
*str += wBuff;
delete[] wBuff;
}
#else
*str += buff;
#endif
delete[] buff;
*pcb = max;
return 0;
}
static DWORD CALLBACK StreamIn( DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb )
{
CString* str = ( ( CString* ) dwCookie );
#ifdef _UNICODE
// Unicode is only supported for SF_TEXT, so we need
// to convert
LPCTSTR ptr = str->GetBuffer( (*str).GetLength() );
int length = ::WideCharToMultiByte( CP_UTF8, 0, ptr, -1, NULL, 0, NULL, NULL );
int max = min( cb, length );
if( length )
{
char* buff = new char[ length ];
::WideCharToMultiByte( CP_UTF8, 0, ptr, -1, buff, length + 1, NULL, NULL );
strncpy( (LPSTR) pbBuff, buff, max );
delete[] buff;
}
str->ReleaseBuffer();
#else
int max = min( cb, (*str).GetLength() );
strncpy( ( LPSTR ) pbBuff, (*str) , max );
#endif
(*str) = (*str).Right( (*str).GetLength() - max );
*pcb = max;
return 0;
}
</code>
If I StreamIn with SF_RTF and StreamOut with SF_TEXT I end up with an empty string or one far too long, but containing the desired data.

Hi,
I have a OpenGlView extended from a CView. I then extend from OpenGLView to get e.g. a TexturedSceneOpenGLView.
However when I do this only the OpenGLView is constructed and the OnPaint and other handlers for TexturedSceneOpenGLView are not called.
Does anyone know how I can make this work or offer any alternative suggestions.
Kind Regards,
flip

I don't understand exactly what your problem is... So you have a OpenGLView class that inherits from CView. Then, you have another class (TexturedSceneOpenGLView) that inherits from OpenGLView ? Is that right ?
And, what is exactly the problem ? Can you post some code ?

flip wrote: Subclassing CView twice with MFC
I think you are refering to deriving, subclassing in windows has a different meaning.
you said that TexturedSceneOpenGLView's OnPaint event is not called, just wanted to know if you have created an instance of that class and made the view visible?

can any one help me out
in convert WAV file to VOX,
Thanks in Advance

I dont know the format of VOX audio, but before you do, you need to get a codec for conversion for doing it programatically.
But if you need a tool, you can search google for any available converter.

I created an SDI in VC++. When I derive classes from MFC classes they are shown in the class wizard and windows message handlers can be added to those classes. When we again derive from these classes which are derived from the MFC classes, those are not shown in the class wizard classes list. So I m having problem adding windows message handlers to those classes which are at the second level of inheritance.
For eg:
I made a class named CListRs with base MFC class CListView. Then when I take the class wizard I can see CListRs in the class name combo box and is able to add message handlers to it. Now I made another class CMailView derived from CListRs. But it is not seen in the class name combo box of the class wizard. So I m unable to add windows message handlers to this class.
Can anyone please help?
Hoping for a reply

Try deleteing your *.CLW file and hit Ctrl+W. This will ask for create class view from exisiting file. add all file and create class view.....

Thanks for the reply. Tried that, but doesnt solve the problem. Now what to do?

Hi,
this is another dirty trick wich I use to do the same thing.
Derive your new class from CListView, this will add your new
class to the CWL. Then replace CListView with CListRS.
This works for me, hope it does the same for you

Can you please tell me how to do that? Thanks in advance
