I'm not quite clear on what you want to achieve. In any case, you cannot use the CString constructor like that in the second case.

The following does indeed compile, though how it could be used in a useful way is still a puzzle. (since it cannot be assigned to anything) :|
void MyFunction() { CString("Hey").Format("There!"); }

That compiles *and* runs successfully. The problem is that
CString::Format's return type isvoid. So that's the return type of this statement, and there doesn't seem to be any way to convert that to the LPCTSTR that AfxMessageBox expects. It's going to take some serious obfuscation to make this work. My question is...what's wrong with a local CString variable? Like it or not, the statement itself is creating a local CString that goes out of scope after the statement executes. Bob Ciora -

Although this is a valid call, isn't it a bit like asking for "unpredictable results" to come your way ?
CString strText( _T("Hey") );
strText += _T(" there !");Much easier, much simpler, and compiles correctly :D -Antti Keskinen ---------------------------------------------- "If we wrote a report stating we saw a jet fighter with a howitzer, who's going to believe us ?" -- R.A.F. pilot quote on seeing a Me 262 armed with a 50mm Mauser cannon.

Its all about trying to show the geekness, wot you feel cing the following. int fun(tchar* buff,tchar* szFnd,int n) { .... .... return CString(buff).Right(n).Find(szFnd); } ;)
