From my past posts explains how to export to excel as
1. Export GridView Data into CSVFile In Asp.net
2. GridView Export to Excel

So here its 3rd type to export to excel using Jquery.

In javascript, we have window.open function. We are using same function to export to excel using jquery.

Syntax,

window.open(MIMEtype,replace);

Here
MIMEtype : this is the optional parameter, and its for type of document. default it take as "text/html"
replace : this is also optional parameter, and its set.

Example,

$("#btn_Export").click(function(e) {
window.open('data:application/vnd.ms-excel,' + $('#divData').html());
e.preventDefault();
});

Hope its helps you.

Find Difference between 2 dates in Year, month, day, hour, minute, second and millisecond.

Posted by Viral Sarvaiya on May 3, 2013


After a long time i get time to post in my blog.

Few day ago i get very good function which finds difference between 2 dates.

Below is the class named “DateTimeSpan.cs”

using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;

public struct DateTimeSpan
{
  private readonly int m_years;
  private readonly int m_months;
  private readonly int m_days;
  private readonly int m_hours;
  private readonly int m_minutes;
  private readonly int m_seconds;

  private readonly int m_milliseconds;
  public DateTimeSpan(int years, int months, int days, int hours, int minutes, int seconds, int milliseconds)
  {
    this.m_years = years;
    this.m_months = months;
    this.m_days = days;
    this.m_hours = hours;
    this.m_minutes = minutes;
    this.m_seconds = seconds;
    this.m_milliseconds = milliseconds;
  }

  public int Years
  {
    get { return m_years; }
  }
  public int Months
  {
    get { return m_months; }
  }
  public int Days
  {
    get { return m_days; }
  }
  public int Hours
  {
    get { return m_hours; }
  }
  public int Minutes
  {
    get { return m_minutes; }
  }
  public int Seconds
  {
    get { return m_seconds; }
  }
  public int Milliseconds
  {
    get { return m_milliseconds; }
  }

  private enum Phase
  {
    Years,
    Months,
    Days,
    Done
  }

  public static DateTimeSpan CompareDates(DateTime date1, DateTime date2)
  {
    if (date2 < date1)
    {
      dynamic sub = date1;
      date1 = date2;
      date2 = sub;
    }

    DateTime current = date1;
    int years = 0;
    int months = 0;
    int days = 0;

    Phase phase__1 = Phase.Years;
    DateTimeSpan span = new DateTimeSpan();

    while (phase__1 != Phase.Done)
    {
      switch (phase__1)
      {
        case Phase.Years:
          if (current.AddYears(years + 1) > date2)
          {
            phase__1 = Phase.Months;
            current = current.AddYears(years);
          }
          else
          {
            years += 1;
          }
          break; // TODO: might not be correct. Was : Exit Select
        break;

        case Phase.Months:
          if (current.AddMonths(months + 1) > date2)
          {
            phase__1 = Phase.Days;
            current = current.AddMonths(months);
          }
          else
          {
            months += 1;
          }
          break; // TODO: might not be correct. Was : Exit Select
        break;

        case Phase.Days:
          if (current.AddDays(days + 1) > date2)
          {
            current = current.AddDays(days);
            dynamic timespan = date2 - current;
            span = new DateTimeSpan(years, months, days, timespan.Hours, timespan.Minutes, timespan.Seconds, timespan.Milliseconds);
            phase__1 = Phase.Done;
          }
          else
          {
            days += 1;
          }
          break; // TODO: might not be correct. Was : Exit Select
        break;
       }
    }
    return span;
  }
}

Now in default.aspx page i am using this structure to get difference between 2 dates as below.

protected void Page_Load(object sender, EventArgs e)
{
  DateTimeSpan datetimespan = new DateTimeSpan(); // Create object of constructer to get difference.

  string date1 = "3-May-2013 9:26:10.011 AM";  //Date 1
  string date2 = "4-June-2014 6:50:20.136 PM";  // date2
  datetimespan = DateTimeSpan.CompareDates(Convert.ToDateTime(date1), Convert.ToDateTime(date2));  //Call static function of DateTimeSpan structure. which return difference of 2 dates.

  Response.Write("Date 1 : " + date1 + "  <br>");
  Response.Write("Date 2 : " + date2 + " <br><br>");

  Response.Write("Years : " + datetimespan.Years + "<br>");
  Response.Write("Months : " + datetimespan.Months + "<br>");
  Response.Write("Days : " + datetimespan.Days + "<br>");
  Response.Write("Hours : " + datetimespan.Hours + "<br>");
  Response.Write("Minutes : " + datetimespan.Minutes + "<br>");
  Response.Write("Seconds : " + datetimespan.Seconds + "<br>");
  Response.Write("Milliseconds : " + datetimespan.Milliseconds + "<br>");

}

This will give difference in all possible ways as below output.

Output

Hope this will helps you.
Thanks.

Delete multiple Procedure/Table/Trigger form sqlserver database

Posted by Viral Sarvaiya on December 14, 2012


In sql server we use one query for drop table/procedure/trigger like below


Drop table table_name
Drop procedure Procedure_name
Drop trigger Trigger_name

But if we want to delete some or all Tables/Procedure/Trigger then what?
have to delete one by one?
We can create one loop with cursor to drop table/procedure/trigger for that as like below.

we can create SP to delete perticulers of the database as passing text and type as a parameter.

For that we can use sys.objects table

For table Type = 'U'
For procedure Type = 'P'
For Trigger Type = 'TR'

For more type of sys.objects please refer http://msdn.microsoft.com/en-us/library/ms190324.aspx

Stored procedure is as below.


ALTER PROCEDURE DeleteEntities
@Type VARCHAR(2),
@SearchText VARCHAR(50)
AS
BEGIN

DECLARE @procName varchar(500)
DECLARE @StrDrop VARCHAR(50)

IF (@type != '')
BEGIN

DECLARE cur cursor

FOR SELECT [name] FROM sys.objects WHERE TYPE = @Type AND NAME LIKE '%'+  @SearchText +'%'
open cur
fetch next from cur into @procName
while @@fetch_status = 0
BEGIN
SET @StrDrop = ((CASE WHEN @Type = 'U' THEN  'drop table '
WHEN @Type = 'P' THEN 'drop Procedure '
WHEN @Type = 'TR' THEN 'Drop trigger '
ELSE ''
END) + @procName)
IF (@StrDrop != '')
BEGIN
EXEC @StrDrop
END

fetch next from cur into @procName
end
close cur
deallocate cur
END

END

As like this we can also drop table constraints.

Hope this will helps you.

Thanks

Handling Window services thru C#

Posted by Viral Sarvaiya on November 23, 2012


Hello.

Open Run window form start menu or Press Window key + R, Run window will open, in textbox type “services.msc” and Hit Enter, Service window will open.

Service window has list of the services installed in the computer.

To these all service we can call Window service in technical word.

Window service enable you to create long-running executable applications.

To know how to create window service please click here

C# provide you functionality to handle installed services, that will include in namespace System.ServiceProcess

Here i am explain, how to handle window service.

1. To get list of the Window service.

You can get list of the window service installed in computer from below code,

In System.ServiceProcess namespace we have a from that we can get list of the window service.


ServiceController[] ListServices = ServiceController.GetServices();

2. Search particular service from list.


ServiceController[] ListServices = ServiceController.GetServices();

string TextService = "My Sample Service"

if (LstServices.Where(a => a.ServiceName == TextService).Count() > 0)
{
ServiceController Myservice = new ServiceController(TextService);
}
else
{
MessageBox.Show(TextService + " is not Installed");
}

ServiceController.GetServices() gives list of the service so i take that in array of the ServiceController class.

And from linq query we can check that particular service is in the list or not and if that list count is greater than zero then we get that service is installed in the computer else not.

And to get that particular service, here i have creating object of the ServiceController class.

3. Check the status of the Service.

If the window service is installed in computer then we can also check the status of that window service.

Now we assume that we find the service "My Sample Service".

So from below code we can get the status of the service whether it is Running, Paused, Stopped.


ServiceControllerStatus ServiceStatus = Myservice.Status;

ServiceControllerStatus is Enum for all service statuses.

If we want to compare status then we can use as like below.


if (ServiceStatus == ServiceControllerStatus.Running)
{
//Do something
}

4. Start/Stop the Service

From ServiceController class we can start or stop the particular Service with object of the ServiceController.

To start the service you can use


Myservice.Start();

And to stop the service you can use


Myservice.Stop();

5. To Restart the Service

To restart the service first we have to check that service is running or not and if it is running then we can stop the service and start the service.


ServiceController[] ListServices = ServiceController.GetServices();

string TextService = "My Sample Service"

if (LstServices.Where(a => a.ServiceName == TextService).Count() > 0)
{
ServiceController Myservice = new ServiceController(TextService);

ServiceControllerStatus ServiceStatus = Myservice.Status;

if (ServiceStatus == ServiceControllerStatus.Running)
{
Myservice.Stop();

TimeSpan timeout = TimeSpan.FromMilliseconds(2000);

Myservice.WaitForStatus(ServiceControllerStatus.Stopped, timeout);  //To wait 2 second for Stop Service

Myservice.Start();

Myservice.WaitForStatus(ServiceControllerStatus.Running, timeout);   // To wait 2 second for Start Service
}
}
else
{
MessageBox.Show(TextService + " is not Installed");
}

hope this will helpful

Thanks.

String.Split – by Multiple Character Delimiter in C#.Net

Posted by Viral Sarvaiya on October 31, 2012


 

Basically String Split function split the string with the single character delimiter;
we take one example of single string of the multiple emails.
If we have comma separated emails then we can use Split function as like below

string strEmailText = "abc.abc@yahoo.com,xyz.xyz@gmail.com,some.text@yahoo.co.in";
string[] strSplitText = strEmailText.Split(",");

this will give us string array of the Emails.

But what if we want to use split with 2 or more than one character?
Means what if i have string as like below

string strEmailText = "abc.abc@yahoo.com,xyz.xyz@gmail.com;some.text@yahoo.co.in,pqr.xyz@msn.com";

at this time above split function will not work with this string. so for that below solution works well.

string strEmailText = "abc.abc@yahoo.com,xyz.xyz@gmail.com;some.text@yahoo.co.in,pqr.xyz@msn.com";
string[] strSplitText = strEmailText.Split(new char[] { ',', ';' }, StringSplitOptions.RemoveEmptyEntries);

this will give you string array of the Emails.

Thanks.
