c++ - '<function-style-cast>' : cannot convert from 'int' to 'CString' -

this code written in visual studio 2003, compile in 2008.

int afxapi afxmessagebox(lpctstr lpsztext, uint ntype = mb_ok, uint nidhelp = 0);  if(iirecd == socket_error || iirecd == 0) {   ierr = ::getlasterror();   afxmessagebox(cstring(ierr));   goto prereturncleanup; } 

in 2003, works fine, in 2008, shows me error:

error 50 error c2440: '<function-style-cast>' : cannot convert 'int' 'cstring'

what error mean?

it's bit hard without information, erroneous code , want there.

here's guess: want convert int cstring, somehow this:

int = 42; cstring str = (cstring)i; 

if you're using mfc/atl cstring try following

int = 42; cstring str; str.format("%d", i); 

cstring::format takes format string printf , stores result in cstring.

edit

i'm interpreting comment below code causes error. bit surrounding text , explanation nice, though.

if(iirecd == socket_error || iirecd == 0) {    ierr = ::getlasterror();   afxmessagebox(cstring(ierr));   goto prereturncleanup;  } 

try change to

if(iirecd == socket_error || iirecd == 0) {    ierr = ::getlasterror();   cstring msg;   msg.format("%d", ierr);   afxmessagebox(msg);   goto prereturncleanup;  } 

one general comment on goto prereturncleanup;: may want take @ raii-idiom (imho) better way such cleanup.
