Hi All,
I have a factory which has some concrete sub classes for generating reports (.txt, .csv,.xls) I want to make the interface of the concrete classes to be generic so that i can pass in diff types of parameters (Instead of DataTable i need to use DataSet or some other class instance as argument). Here is my previous interface.

  interface IReportCreator
  {
        bool Create(DataTable dt);
  }

I made the interface as generic..like the one below

interface IReportCreator<T>
{
    bool Create(T args);
}

Now my question is how can i return the generic interface from the Factory My previous factory code
My previous factory code is like the one below..

class Factory
{
    static IReportCreator  GetReportCreator(string type)
    {
        IReportCreator reportCreator = null;
        if(type == "txt")
            reportCreator = new TextCreator(); 

        if(type == "csv")
            reportCreator = new CSVCreator();

        return reportCreator;
    } 
}

And in the cient.. i call like this

IReportCreator repCreator = Factory.GetReportCreator("txt"); 
repCreator.Create(// the argument);

I want to make the factory as a generic one.. Pls help me to solve this

Any help will be appreciated greatly
Thanks

Hi All,

I have developed a web site in ASP.NET in 3 tier architecture (Presentation layer, BusinessLayer, DataLayer). Now the client is looking for an entire look and feel for UI, which consist of lots of jquery sliding / animated features etc. (Few pages will get loaded in a frame with sliding and as modal pop up). I want to know whether i can apply any design patterns or architectural pattern for developing the new UI with the existing business and data layer.

Hi All,

I need to implement a searching feature in my web site. My web site is a Shopping site having different categories (like ebay). There is a general search textbox at the top of the page, if a user types in "Guitar" and clicks the search button it should search in our database and should provide the search result.Writing queries to search for the specific word in whole categories and subcategories can take more resource. How can i implement the searching feature? Any available free search engine to my web site which pulls the data from my database? Please help me to solve this.
