Interfaces are class type that provide only function and method decleration without implementation. It is known as the blue print of classes, since classes needs to provide the implementation for their interfaces.

We use interface to enforce same name convention to similar operation, let say we have build an application with objects that perform update and insert operation into the database. Without implementation of the same interface each object can have different name for the insert operation, one object can use the InsertNew method name, another object can use the method name InsertMe. In this case interfaces are enforcing object that implement the interface to use the same name convention declared inside the interface.

This is a really big issue when you start building collection of the same type and each type has a different name convention to same operation. In this case you cannot create a generic code that will handle all object type in the same way because of the different methods name convention.

The example based on Tim Stall article in 4 Guys from rolla. com

If we have a dynamic page that according to parameters in the querystring retrieves data from User Control ( user define control that uses different method names for similar operation in this case fetching the value of the control)

// Determine what User Control was loaded based on the querystring value
string strSection = Request.QueryString["Section"];

string str = "";

// Use a switch statement to reference the correct User Control

switch (strSection) 

{
         case "A":
                 str = ((NoneA)this.PlaceHolder1.Controls[0]).ControlData;
                 break;
         case "B":
                 str = ((NoneB)this.PlaceHolder1.Controls[0]).Values;
                 break;
         case "C":
                 str = ((NoneC)this.PlaceHolder1.Controls[0]).SelectedItems;
                 break;
}; //end of switch-case

Each optional  control on the page has a different method to extract the value

                One control uses the conrolData  ( user control)

                Value for text box control

                Selected item for list view control.

The brut approches uses the switch statement to read the query string parameter value and accordenly it will execute a different method to extract the control value.

 No matter which type of control :

(this.PlaceHolder1.Controls[0]).GetData;

However if the user control all implemented the same interface that enforce them to use the same name conventions, the end result will be that, instead of a switch statement, you can execute the same method name on different controls type, and therefore, eliminating the switch statement. This solution will also enable more controls to be created implementing the same interface and the code will work for those new controls without the need to change it.

What are .RDL files ?

Stands for report definition language.

Xml syntax that contains the report definition.

Can be created with the ms SQL server intelligence studio.

Where do publish the reports ?

            Deploy to a report server.

What files you need to download?

Sql server advanced.

Swl server tools.

Where can you define the virtual location of you report services. :

                        Configure report server.

What is the use for the database setup in the configure report server tools :

            Uses to control report cashing

            Saving information on the reports created by the report services.

OnClientClick

=<%# String.Format(“return checkMe(‘{0}’);”, (Container.DataItemIndex + 2).ToString().PadLeft(2, ’0′)) %>

 Using a shorthand if statement to present icon when a rule is satisfied, in this example if the field vp_submited ( Boolean in the database ) is equal to 1 then show an icon representing a submitted status.
<%# (( Convert.ToInt16(DataBinder.Eval(Container.DataItem, “vp_Submited”)) == 1) ? “<img src=’images/Flag2_Green.png’ />”:“&nbsp;”) %>
 

 The current index in a repeater control :
<%# Container.ItemIndex.ToString(“00″)%>
id=’in_sysId_<%# Container.ItemIndex.ToString(“00″)%>‘

 different ways to use Eval statment : 

#Bind
You will need to use the #Bind For 2 way databinding where you want to update or insert a record with the use of a data source.
#Eval
Read-only databinding, where the control only presents a value without updating capabilities. 

<%# “<b>” + Eval(“PK_VehiclePageSysId”) +“</b>”%>
 SelectedValue=’<%# Eval(“vp_PageType”) %>‘

Calling to a function from within the aspx code, the function is located in the codebehinde (or at the same page in the server side script level), in this example the function return a Boolean value for an asp:checkbox control, in order to determine if to show a checked status.

Checked=’<%# GetDeletedStatus(Eval(“recStatus”).ToString()) %>‘

In this example the image url and visablity are determine by the return value of the functions:

src=’<%# GetImageUrl(Eval(“ImageName”).ToString(), Eval(“OriginalFileName”).ToString()) %>‘ visible=’<%# SetImageVisibility(“Left”) %>‘

The current index :

repeater control:
 <%# Container.ItemIndex.ToString(“00″)%>
 id=’in_sysId_<%# Container.ItemIndex.ToString(“00″)%>‘

grid control :

<%# (Container.DataItemIndex + 2).ToString().PadLeft(2, ’0′) %>

SELECT ShiptoPlant, CleanString([ShiptoPlant]) AS Clean

the golobal public function inside a module 

Function CleanString(strText) 
Dim objRegEx As Object 
 
Set objRegEx = CreateObject("VBScript.RegExp") 
objRegEx.IgnoreCase = True 
objRegEx.Global = True 
 
objRegEx.Pattern = "[^a-z0-9]" 
CleanString = objRegEx.Replace(strText, "") 
 
End Function 

            1 ) bind the form to a table.

            2) Any additional view information you need to present can be bind to the controls with the use of a module public function that retrieves the data needed.

1. How do you submit a page in java script through code :

                        Document.form.FormName.submit();

                        Document.forms[“formName”].submit();

                        Document.forms[0].submit();

                        Document.getElementById[“formName”].submit();

2.   What will be the advantage of using document.forms[0].submit over the other options?
                        using the form collection with an index will give you more dynamic approach in this case the form name can be changed and it will not require the change of the submit code. Disadvantage: in a multi form page, it is  harder to trace which form is being submit since there is no explicit indication of the form name.

3. You have a document.form.formName.submit() code that doesn’t work, what will be your approach of debugging the problem?

1. I would make sure that the form name is correct (syntax).
2. Check for duplication in elements with the same name.
3. Check there is no element name submits in my form.

4. when you get the error message “object doesn’t support this property or method” what will be your first steps in debugging the problem ?
                        make sure I am targeting the right object

I will use alert with tagName and typeOf  and object name do verify that I am targeting the right object.

5. How would you reefer to container document from inside his child frame. ?
                                    I will use the top keyword.

Microsoft Access Tips for Serious Users

Field type reference – names and values for DDL, DAO, and ADOX

You can create and manage tables in Access using:

• the interface (table design view);
• Data Definition Language (DDL) query statements;
• DAO code;
• ADOX code.

Each approach uses different names for the same field types. This reference provides a comparison.

For code to convert the DAO number into a field type name, see FieldTypeName().
