• Re: Generics and the Type object

  [quote user="pauldavidson"]I have the need to create a generic class, however I will not know when I instantiate the object what type it will be, all I will have is the string of what type it should represent. [/quote] Why do you want to/need to do this? I think that you're trying to complicate something that could be simpler. The point of generics is to be able to work with strongly typed, but somewhat flexible implementations. Can you explain a little further what you're really

• Re: how to get base type functionality?

  [quote user="mariafinley"] how to implement class that extend base type functionality.[/quote] As mentioned, you can't extend the System.String class. You should not implement extension methods unless you specifically need them. They are fraught with some real dangers, and they make the code much less readable when misused. You have two choices basically: Implement a (static) helper method of a suitable class to do your custom parsing. Implement a wrapper object for your specially formatted

• Re: Generics and the Type object

  [quote user="SvDeursen"]it's a premature to conclude that this isn't the right approach[/quote] Absolutely! I'm sorry if I gave that impression. I do, however, suspect that it isn't the right approach - but I'm hoping for some more info about the actual case. Generally speaking, when there really is a good reason for this very dynamic approach, perhaps C# is not the language of choice... Certainly possible, but perhaps not the best choice of tool. Then again, it might

• Re: how to call static class?

  In a standard Web Project, you should place common utility code in the App_Code folder. This will cause ASP.NET to compile it into an assembly that is available to your other code in code behinds and .aspx files etc.

• Re: overloading existing String method

  [quote user="thewatcheruatu"]extension methods, but didn't want to get all into that unless I knew that I had [/quote] Extension methods should indeed be avoided unless required. In this case, they will not help you since an extension method does *not* override an existing method of the same signature. The correct answer to your original question "overloading existing String method" is: You can't and you should not. You can, but should probably not, create an extension

• Re: namespace guidlines

  Golden rule: Write for human readers, not compilers or tools. Code is typically write once or twice, read many. Therefore: If your class is a business object forge, should should certainly name it BusinessObjectForge (and use HostingSolutions as the namespace to answer your original question). Bytes are cheap but people are expensive, and with Intellisense you don't even have to exercise your fingers to type them...

• Re: convert to byte to binary

  [quote user="munish_ps"]the right way of converting[/quote] The right way of converting depends on what you're getting as input. You say you "loose a lot of data" when you use the UTF8-decoder, that's probably because what you're getting is not UTF-8 encoded text. Your BitConverter.ToString() will get a hexadecimal representation of the binary data - you'll still have to interpret it to something useful with. You have to *know* what your input is. What is your

• Re: Using MD5 for password storage

  [quote user="eddy556"]MD5 is still suitable for encryption[/quote] This is just the point. By asking this question, you clearly indicate that you are not experienced enough in this field. MD5 is a cryptographic hash. Not an encryption algorithm. It is never used for encryption. (Correction - it should never be used for encryption, but I am aware of people who mistakenly do...) Passwords should not be encryped. They should be hashed. With a cryptographically strong hashing algorithm, which

• Re: Using MD5 for password storage

  Let's see if I can say this in a nice way. Assuming web site security is important (some would even say that it's vital), it should be fairly clear that to implement it, the implementer must know how to do so. From your initial attempt, the main question, and follow up question, I can only conclude that you do not yet have the experience required to implement such a function. In fact, few do. Unfortunately, this is not as easy as just putting you right on the main issues above (no, MD5 is

• Re: e-mail sending failed after deploying the page on website

  To elaborate a bit: Your hosting provider, or equivalent, appears to have restricted SMTP access. Exactly how is hard to tell, if you look at http://msdn.microsoft.com/en-us/library/system.net.mail.smtpaccess.aspx you'll see there are two levels of restriction 'Connect' and 'None'. If your hosting provider has set 'None' you're out of luck, if it's 'Connect', you'll probably just have to ask them for the name of a relaying smtp server that they do allow
