If you need to write a UNICODE file the code I provided works fine but you have to put the proper BOM at the very start of the file, for instance

  TCHAR * szIn = _T("http://sharepoint/Docs");
  ofstream of("foo.txt", ios::out);
#ifdef _UNICODE
  TCHAR BOM = 0xFEFF;
  of.write((const char *) &BOM, sizeof(TCHAR));
#endif
  of.write((const char *) szIn, _tcslen(szIn)* sizeof(TCHAR));
  of.close();

On the other hand, if you need to write a ANSI file then follow Naveen suggestion: use wofstream instead of ofstream.

Since your writing a wide char text, either you have to use wofstream instead of ofstream or
Covert the elementValue[i] to mutibyte using sprintf() or WideCharToMultiByte() before writing..

Dynamically drawing 10 images to an area depends on the no of pixels.. Do you checked the minimum pixel area required to fit 10 image in the dialog bar

Ex if i want to draw 10 buttons with respect to the Size of the CDialogBar in a mainframe.
Then it should exactly fit to the screen.

Don't "draw" them yourself. Simply create them dynamically using CreateWindow.

I hope you mean wide characters(UNICODE) and multi byte characters. Try the IsTextUnicode() function.
