#### save string as unicode

This problem is solving itself piece by piece. I have a legacy VC 6 application and have to fix it to produce a unicode file.
By turning on 'see display unicode string option on under tools/options/debug' I now know that the string I have actually does have the unciode entity.  But the routine used bty the application to save any strings is not working correctly - it saves the unicode as ?.

Can anyone show me a very simple code snippet to do this !  I know there is information about settiings...I need to be able check this large application for the settings, ( help please ), drop in the snippet, then go back and see why/if the existing file save code is failing. ( I need to fix the existing one if my settings are correct  - because of the extensive business logic the application does to the strings(s) that form the file.  Thanks Andrew

Hi Andrew,

>But the routine used bty the application to save any strings is not
working correctly - it saves the unicode as ?.
>
Do have checked its binary code? Maybe the Unicode string has already been
saved, but the file is not saved as an Unicode txt file. (If a txt file's
first 2 bytes is 0xFF and 0xFE��it is Unicode file��else it is an ANSI txt
file.)

What's routine do you use to save the Unicode string?
How about copy the Unicode string into a TCHAR array first, then save the
TCHAR array to the target file:
TCHAR szBuffer[MAX_LENGTH];
_tcscpy(szBuffere, (LPCTSTR) szUnicode);

Thanks!

I tried this but content did not have the enity ( small delta ) I expected. The file looks the same - although I inspected the
memory location of cstrHTML . Is there some other value(s) that need to be in place ???  Thank

CString cstrHTML(bstrHTML)
CFile		fOutFile
CFileException	exception
int		status

const int MAX_LENGTH=20000
TCHAR szBuffer[MAX_LENGTH]
_tcscpy(szBuffer, (LPCTSTR) cstrHTML);
CString htmlPath
htmlPath = "c:\\delta.html"
status = fOutFile.Open(htmlPath,
CFile::modeCreate | CFile::modeWrite | CFile::shareExclusive, &exception)
fOutFile.Write ( szBuffer,  cstrHTML.GetLength())

Hi Andrew,

Do you have checked the following MSDN doc:
Unicode Topics
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HT
ML/_core_unicode_topics.asp

Strings: Unicode and Multibyte Character Set (MBCS) Support
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HT
ML/_core_strings.3a_.unicode_and_multibyte_character_set_.28.mbcs.29_.suppor
t.asp

I think you may not  have a Unicode versions of the MFC libraries
installed, the Unicode versions of the MFC libraries are not copied to your
hard drive unless you select them during a Custom installation.

Wish it helps!

You are right, unicode MFC is not the default in VC6 ++ and if you had not told me I would never have kept selecting the options - it was really deeply nested

As for seeing if I should use unicode or isolate it or do all this specific task work in TCHAR ... I don't know - I summerized the facts and now other big-cheeses can decide. Thanks for the many replies and help !

Why do PDF attachments in OWA 2003 need to be saved before opening?

Is there any way to prevent that and allow them open it directly please? They can do that with Word attachments, for example. PDF isn't mentioned in the Level1 or Level2 lists. And what's annoying is that if they right-click on the attachment, then one of the IE options is "Open" anyway. Go figure. Thanks, - Alan.
