also add UNICODE
never say die

Sir,
What is the significance of adding UNICODE / _UNICODE? It's actually now I removed _UNICODE and added UNICODE, the app still understands unicode. I kept both UNICODE AND _UNICODE, the app still works with unicode.  I don't understand this. Can someone explain me in detail? I went through The msdn documentation regarding the same, but didn't get it. (In all the cases I had to define an entry point by myself i.e. entry:wBlah, otherwise the compiler gave a bitter error complaining _WinMain@16 is an unresolved external symbol!)
Thanks,
Aljechin Alexander

the two macros exist, but not manages the same places. so, the best way to handle unicode fully is to define the 2 macros this way (in stdafx.h for instance) :
<font color=green>
<font color=blue>#define</font> _UNICODE
<font color=blue>#define</font> UNICODE
<font color=green>

yes and this need to put preferablely in stdafx.h or any common header file that is included in all the files so that the project is compiled uniformly or add it to the project settings.

_UNICODE for C like wsprintf
UNICODE for Microsoft Function/API

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.
Reference:
CRichEditCtrl::StreamOut[^]

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 ?

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.
