I need to create a function that checks to see if a password that the user creates is 'strong' enough. The password must contain an uppercase letter, a lowercase letter, a number and a special character. The part I'm having trouble with is the checking for lower or uppercase. Is there some hidden asp function that I don't know about that might tell me if a lowercase or uppercase character exists in a string? I know that C# has a isLower() function but I don't think ASP does. What would be the best way to test for this? Any help is greatly appreciated. Thanks.
