Generating KnockOut ViewModel from a sql table

Here is the script that can be used to generate a Knockout V.M. from a table




DECLARE @TableName VARCHAR(100) = 'Persons'
DECLARE @ShortTableName varchar(100) = 'person'
DECLARE @TableSchema VARCHAR(3) = 'dbo'
DECLARE @result varchar(max) = ''


SET @result = @result + CHAR(13)


SET @result = @result + 'var ' + @TableName +  'VM = function('+ @ShortTableName +'){' + CHAR(13)

set @result = @result + 'var self = this ;' + char(13)

SELECT @result = @result + CHAR(13)
     + 'self.' + ColumnName + ' = ko.observable(' + @ShortTableName + ' ? ' + @ShortTableName +'.' +ColumnName +' : '''');' + CHAR(13)
FROM
(
    SELECT  c.COLUMN_NAME   AS ColumnName
        , 'var' AS ColumnType
        , c.ORDINAL_POSITION
FROM    INFORMATION_SCHEMA.COLUMNS c
WHERE   c.TABLE_NAME = @TableName and ISNULL(@TableSchema, c.TABLE_SCHEMA) = c.TABLE_SCHEMA
) t
ORDER BY t.ORDINAL_POSITION


SET @result = @result  + '}' + CHAR(13)



PRINT @result

Enabling Tracing for WCF Service

If you want to enable tracing for your WCF Service Copy Paste following code under configuration


<system.diagnostics>
    <sources>
      <source name="System.ServiceModel" switchValue="Information, ActivityTracing"
          propagateActivity="true">
        <listeners>
          <add type="System.Diagnostics.DefaultTraceListener" name="Default">
            <filter type="" />
          </add>
          <add name="ServiceModelTraceListener">
            <filter type="" />
          </add>
        </listeners>
      </source>
    </sources>
    <sharedListeners>
      <add initializeData="C:\temp\web_tracelog.svclog" type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
          name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
        <filter type="" />
      </add>
    </sharedListeners>
    <trace autoflush="true"/>
  </system.diagnostics>

Frequently Used JQuery functions for select list


Clearing a Select list:
$("#select_list_name").empty();


Adding an option in Select List:
$("# select_list_name ").append($('<option>', {
                            value: value_to_add,
                            text: text_to_add
                        }));
Here ‘value_to_add’ & text_to_add aer values that you want to be added.



To Check if an option exist by value in a Select List:
if ($('#select_list_name).find('option[value=' + value_to_search + ']').length > 0)
{
       //When an Item exist
}

Here value_to_search is the value that you want to searched in select list.


To select a particular value in select list after you find it:
$('#select_list_name).find('option[value=' + value_to_search + ']').attr("selected", "selected");


To read a selected value:
var selectedvalue = $("#select_list_name option:selected").val();


To set Margin value & Width for select list:
$('#select_list_name').css('margin-left', '5px');
$('#select_list_name ').css('width', (window.screen.width * 0.14) + 'px');

Setting up NAnt on your pc/server

In this post we are going to see how to set up NANT on your PC/Server. Its first step towards Build Automation.



1.       Download Nant Binaries from http://nant.sourceforge.net/


2.       Once you download all Binary files, right click on Zip file and open Properties as show below


3.       Once properties window opens click on Unblock button as shown below



4.       Now unzip the Zipped file contents at some preferred location for eg. C:\Program Files (x86)\ Nant, as show below.




5.       Now go to “My Computer “ => “Advanced System Settings” => “Environment Variables”
And add following “System variable” as shown below


6.       Edit “Path” Variable in System Variables section as show below, append newly added system variable in your existing paths

 

7.       Open a command prompt and type “Nant – help”, you should see o/p like this.

LINQ to Excell


I am going to share a code sample where I am going to read data from excell and use Linq Query to process that data.

            //declaring all variables that I will use
            Workbook workBook;
            IEnumerable<Sheet> workSheets;
