wamp server turn to yellow color

When I install wamp sever on my laptop, I face subjected problem. The wamp server turns to yellow instead of green. To fix it follow below mentioned steps:

1) Stop IIS Server (type inetmgr.exe in run command)
2) Locate httpd.config file (default path is C:\wamp\bin\apache\Apache2.2.21\conf)
3) Locate below lines
#Listen 12.34.56.78:80
Listen 80

and change them with
#Listen 12.34.56.78:8080
Listen 8080.

Save httpd.config file and restart wamp services. You can see that it will be now changed into green color.

Cannot use the special principal 'sa'. (Microsoft SQL Server, Error: 15405)

Yesterday, I start SQL Server 2005 and try to connect with sa user but was enable to connect with the 'sa' user and got this error:

Cannot use the special principal 'sa' (Microsoft SQL Server, Error: 15405)

After doing some google, I found out the solution which I am sharing so that others can get all the possible solutions from this article.

The titled message mean that your sa user is disabled. To enable it, you have to follow below mentioned steps:

1) you have to change the authentication mode: go to Management Studio and open Object Explorer. Connect to your server and right-click on the server name, then select Properties. Go to Security tab and under Server Authentication select "SQL Server and Windows Authentication Mode".

2) Also, after you follow the directions above, you will also need to explicitly enable the sa account as well. Go to Security->Logins. Right-click on the "sa" account, select "Properties". In the list on the left, select "Status" and under "Login" on the right, make sure "Enable" is selected.

3) exec sp_changedbowner 'sa','true' in query editor after selecting the database whom you want to assign user sa.

4) You can also change the password of sa (it's better to change the password).

After performing all above mentioned changes, Exit with SQL Management Studio. Restart Sql Service from services.msc.

Open Management Studio again and try to login "sa". Hopefully, it works. Enjoy!

EXTRACT DATA FROM XLS AND XLSX FILE FORMAT

Dear All,

Todays post is about how to load data from excel sheet. This post is emphasized on following file formats:

1) xls (Excel Sheet 1997-2003)

2) xlsx (Excel Sheet 2007)

Both sheets require connection string to extract data from sheet.

Connection String for xls:

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Sample1.xls;Extended Properties=Excel 8.0"

Connection String for xlsx:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Sample.xlsx;Extended Properties=Excel 12.0"

Below is a small program for your understanding. The program is in ASP.NET.

protected void Page_Load(object sender, EventArgs e)

{

string connString = ConfigurationManager.ConnectionStrings["xls"].ConnectionString;

// Create the connection object

OleDbConnection oledbConn = new OleDbConnection(connString);

// Open connection

oledbConn.Open();

// Create OleDbCommand object and select data from worksheet Sheet1

OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", oledbConn);

// Create new OleDbDataAdapter

OleDbDataAdapter oleda = new OleDbDataAdapter();

oleda.SelectCommand = cmd;

// Create a DataSet which will hold the data extracted from the worksheet.

DataSet ds = new DataSet();

// Fill the DataSet from the data extracted from the worksheet.

oleda.Fill(ds, "Employees");

// Bind the data to the GridView

GridView1.DataSource = ds.Tables[0].DefaultView;

GridView1.DataBind();

}

I hope this will help you.

SQL Statement OpenDataSource

SELECT *

FROM OPENDATASOURCE('SQLNCLI',

The credentials you provided for the SQL server Agent service are invalid. To continue, provide valid account and password for the SQL server Agent Service.

Today, I have decided to install SQL SERVER 2008 on my PC. All was going fine until I came to server configuration page/tab. I was halted for half an hour to insert correct credential to move to the next page. If you are also getting the same trouble then just enter following data in Account name and password:

Account Name : "NT AUTHORITY\NETWORK SERVICE "

Password : Blank

I hope this will resolve your issue.

FORMATTING NUMBERS IN SQL

HOW TO REMOVE PRINTER DRIVER

You can remove printer driver by following steps that are defined below:

1. Go to Printers & Faxes

2. Delete the printer configuration in question. (For safety's sake, you may want to consider deleting all printer configurations to ensure that you aren't still using some element of the driver in another configuration somewhere. Remember that a driver is often times more than just a single file. It may involve shared libraries in use by multiple printer configurations.)

3. Go to File --> Server Properties

4. Go to the Drivers tab. You will be presented with a list of drivers.

5. Select a Driver and press the "Remove" button.
