Drawing UPC-A Barcodes with C# - CodeProject
6 Apr 2005 ... Demonstrates a method to draw UPC-A barcodes using C#.

If true, switches caching on. It s false by default. Uses a value from the DataSourceCacheExpiry enumeration Absolute for absolute expiration (which times out after a fixed interval of time), or Sliding for sliding expiration (which resets the time window every time the data object is retrieved from the cache). Determines the number of seconds to cache the data object. If you are using sliding expiration, the time limit is reset every time the object is retrieved from the cache. The default value, 0, keeps cached items perpetually. Allow you to make a cached item dependent on another item in the data cache (CacheKeyDependency) or on a table in your database (SqlCacheDependency). Dependencies are discussed in the Cache Dependencies section.

When you enable caching for the SqlDataSource control, you cache the results of the SelectCommand. However, if you create a select query that takes parameters, the SqlDataSource will cache a separate result for every set of parameter values.

Each group of objects is called a data provider and is housed in its own namespace For example, Microsoft ships all of the following data providers:.

#footer { clear : both; } * html #left-container { left : 300px; } If you were to view the HTML code from Listing 6-8 using only the preceding CSS, the display in Firefox would be similar to the screen in Figure 6-4. The bottom half of this figure shows the Firebug console as it integrates into Firefox.

format that the DataSet uses. These are data-provider-specific. However, their basic mechanisms are the same across the board. Their Fill() method causes data to be pulled from the database into a DataSet, and their Update() method pushes any changes made to the DataSet back to the database, as shown in Figure 5-4.

Figure 24-7. Retrieving data from the cache There are two SqlDataSource controls at work in this example. The first SqlDataSource gets the list of cities for the drop-down list. These results don t change often, and so they are cached for one hour (3600 seconds): <asp:SqlDataSource ID="sourceEmployeeCities" runat="server" ProviderName="System.Data.SqlClient" EnableCaching="True" CacheDuration="3600" ConnectionString="<%$ ConnectionStrings:Northwind %>" SelectCommand="SELECT DISTINCT City FROM Employees"> </asp:SqlDataSource> <asp:DropDownList ID="lstCities" runat="server" DataSourceID="sourceEmployeeCities" DataTextField="City" AutoPostBack="True"> </asp:DropDownList> The second SqlDataSource gets the employees in the currently selected city. These results are cached for 600 seconds and bound to a GridView: <asp:SqlDataSource ID="sourceEmployees" runat="server" ProviderName="System.Data.SqlClient" EnableCaching="True" CacheDuration="600" ConnectionString="<%$ ConnectionStrings:Northwind %>" SelectCommand="SELECT EmployeeID, FirstName, LastName, Title, City FROM Employees WHERE City=@City"> <SelectParameters> <asp:ControlParameter ControlID="lstCities" Name="City"

Firebug is arguably the most powerful web development plug-in available for Firefox. While the Web Tip Developer toolbar has been around for longer and is also very useful, the CSS and DOM inspection capabilities, as well as the ability to debug subrequests made with XMLHttpRequest, make it a must-have plug-in. You can download Firebug from http://www.getfirebug.com.

PropertyName="SelectedValue" /> </SelectParameters> </asp:SqlDataSource> <asp:GridView ID="GridView1" runat="server" DataSourceID="sourceEmployees" ... > ... </asp:GridView> This SqlDataSource is a bit more sophisticated because it uses a parameter. Each time you select a city, a separate query is performed to get just the matching employees in that city. The query is used to fill a DataSet, which is then cached for up to ten minutes (600 seconds). If you select a different city, the process repeats, and the new DataSet is cached separately. However, if you pick a city that you or another user has already requested, the appropriate DataSet is fetched from the cache (provided it hasn t yet expired). Thus, this single SqlDataSource can result in a surprisingly large number of cache entries. If there are 20 different cities in your list (and therefore 20 different possible parameter values), you can end up with as many as 20 different DataSet objects in the cache at once.
