[RESOLVED] DateTime format validation method using DateTime.TryParse() always returns false??

If you're not going to do anything with the result of a .TryParse in VB.NET you can set the result to Nothing rather than creating a temporary variable you need to get rid of.

Good call on that. Actually up until now I've never considered having Nothing as the return on a .TryParse(). Thanks!

It's not that you're using Nothing as the return. The return value is a Boolean regardless. The output parameter is a DateTime. If you pass Nothing to that parameter then, inside the TryParse method, it will receive the default value for the DateTime type, which is #1/01/0001#. If the conversion works then the method will assign the appropriate DateTime value to the parameter and that is what the method outputs. The only difference is that, because you used a literal rather than a variable, you don't have access to that output value.
