Well, you actually can do that:

try
{
  CStringArray ss;
  ss.RemoveAll();
  ss.ElementAt(1);
}
catch(...)
{
  AfxMessageBox("Get invalid element");
}

You'll get the assertion just with DEBUG build. RELEASE build will not assert.

Cpallini is right. Assertions are made only in Debug builds. The exception will be thrown in Release builds.

To set the RELEASE build, choose 'Build->Configuration Manager' menu item and then set 'Active solution configuration' to 'Release' (at least on VS 2005...).
