• Re: How can I pass a null value for an integer (value type) parameter and then check if this integer parameter is null?

  If you are using .NET 2.0 you can use nullable types. All you have to do is declare you int as int? instead. The nullable type will give you some extra properties you don't have with a strict value type. For instance you can do the following: int? mID = null; if(mID.HasValue) { ProductService.GetAllProductsByID(mID.Value); } If you aren't using .NET 2.0 then you can use the MinValue of whatever value type you are using. Technically there is a risk that the following method is unsafe code

• Re: Deleting a file

  Well you wouldn't do this with a Webservice, you would want a Windows service. You can schedule windows services to run automatically. Here's an article on writing windows services.. http://www.developer.com/net/csharp/article.php/2173801 Just a word of caution, keep all of your business logic out of the service project. Windows services are very difficult to debug. If you have a class that does all the work and you just call one method on that class to do all that you need then you can wire

• Re: Deleting a file

  There are many ways to approach this problem. One way I would consider is to write a simple windows service that cleans up this folder on a schedule.

• Re: Delete file from folder....

  you want to use the FileInfo class in System.IO. This is pseudo code, but it goes something like this.. FileInfo file = new FileInfo(@"C:\SomeFileToDelete.txt"); if(file.Exists) { file.Delete(); } That should do it...

• Re: Wrapping table columns to fit on one page

  Instead of trying to do this with tables, you could achieve the desired effect by using a series of DIVs and setting the container DIV to a class that uses the CSS float:left property. This will stack as many DIVs next to each other as long as there is room on the screen. Should you have left over DIVs they will break to the next line... this will make your layout liquid as well.

• Re: LinkButton Post back

  The standard approach which you suggest here is ususally the right way, but won't work in your situation. The browser decides what links have been visited by looking at the browsing history. Since this is an ASP.NET postback the link in the href of your anchor tag is to a JavaScript function. Therefore the browser can't tell if you have been to that link or not. The best way to achieve your desired result is to assign the control a .visited class that you can create on post back. HTH, Craig

• Re: Proper way to populate a DDL with n-tier architecture?

  There's an old saying that goes something like, "If you dare to ask for the proper way to do a thing, expect to get 5 answers from the 4 people you ask." I like the method of having a class that will handle talking to your data access classes to get the data from the database and then return the collection up to the user interface. Taking abstraction even a step further I like to use a class I call DataSourceContainer which contains the data source, DataTextField value and the DataValueField
