Destroy CString instance?

[Oliver123]

Suppose I have the following function which is executed many times in a program. Is a separate CString textSub instance created each time the function executes? Do I need to destroy the CString textSub at the end of the function? Or suppose it wasn't CString, but some other class? Thanks. void CNew1Dlg::OnBUTTONPick() { CString textSub; textSub.Format("%d %s", someNumber, someString); GetDlgItem(someEditBox)->SetWindowText(textSub); }

Of course. You don't need to clean it up, it's not a pointer, it will clean itself up ( calling it's own destructor )

Unless you use a "new" operator explicitly,it gets cleaned up automatically once it looses it's scope (Once it returns back to the caller). If you had used "new" to instantiate the object,then you need to "delete" it mannualy.

Another important thing is: sometimes you'll need to call GetBuffer() or another function of that kind, if you do that, you must remember to call also ReleaseBuffer() just before exiting the scope of the CString variable. Hope this helps
