DWORD to LPCWSTR

All replies

• MessageBox(NULL, TEXT((LPCWSTR)data), L"", MB_ICONINFORMATION | MB_OK);
  

• Error    1    error C2275: 'LPCWSTR' : illegal use of this type as an expression

  I encountered this error...

  
  

• Is there a way to convert dword to string directly?
  Like 0xffffff to "16777215"
  

• The 2nd argument to MessageBox() has to be a string of characters (UNICODE, or ASCii)

  (LPCWSTR)data will not add the null character at the end of 0xffffff

• Also consider a solution like this:
  

  
  DWORD data = 0xFFFFFF;

  TCHAR s[100];

  _stprintf_s(s, _T("%X"), data);

  MessageBox(NULL, s, _T(""), MB_ICONINFORMATION | MB_OK);

  Instead of %X you can use %i or other described in documentation for sprintf. There are more solutions for MFC and STL.

• Error    1    error C2664: 'sprintf' : cannot convert parameter 1 from 'TCHAR [255]' to 'char *'

  I encountered this error

  It also says that it is depreciated

  String convertions i'm using sprintf_s

  I forgot to say that just a newbie in C++ Win32 sorry for that.

• Use _stprintf_s() instead of sprintf()

• Complementing Jijo's suggestion :

  TCHAR s[5];

  _itot_s((int)data, s, 5, 10);

  will do it.
