• Overload with different return type in java?

  - by nunos

  So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.

• FormsAuthentication AuthCookie data type

  - by FreshCode

  Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.

• Determining if types alias to the same underlying type in C++

  - by emchristiansen

  I'd like to write a templated function which changes its behavior depending on template class types passed in. To do this, I'd like to determine the type passed in. For example, something like this: template <class T> void foo() { if (T == int) { // Sadly, this sort of comparison doesn't work printf("Template parameter was int\n"); } else if (T == char) { printf("Template parameter was char\n"); } } Is this possible?
