Cannot open database "E_learning" requested by the login. The login failed.

Question

I have created an application that takes a file and saves it into database.
Here is the code

C#

int len = FileUpload1.PostedFile.ContentLength;
byte[] pic = new byte[len];
FileUpload1.PostedFile.InputStream.Read(pic, 0, len);
cnn.Open();
cmd = new SqlCommand("insert into images values='" + pic + "'", cnn);
cmd.ExecuteNonQuery();

but when I click on upload it gives me the following error
Cannot open database "E_learning" requested by the login. The login failed.

I know it is because I have not used the uid and pwd options in database connection string. Actually I am using the windows authentication mode in sql server. There is no user created for the login through sql authentication mode, although I have created one, but it doesnt work.
Can anybody help to solve my problem?

try to make a connection string exactly the same as the authentication method which is used when connecting with SSMS, to resolve the problem.

Looks your connection string is not right and it will have to be in the format of

Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;

Please refer http://www.connectionstrings.com/sql-server-2005[^] for further information.

Also, its worth checking whether you are able to open the SQL server in the windows authentication mode.
