Error accessing report: error for sending(saving) data to database

Hi,

I’m using VS2005 and I’m trying to link the C# windows form to MSSQL. I used BindingNavigator Control to read the data. After that I add sqlcommand and sqldataadapter to send the data to the database. My code is this

sqlDataAdapter1.InsertCommand.CommandText =

"INSERT INTO SUDENT (" +

"S_ID, S_NAME, S_ADDRESS, S_PHONE" +

") VALUES ('" +

S_IDComboBox.Text +"', '" +

S_NAMETextBox.Text +"', '" +

S_ADDRESSTextBox.Text +"', '" +

S_PHONETextBox.Text +"')";

sqlDataAdapter1.InsertCommand.ExecuteNonQuery();

It gave me this error

“NulleferenceException was Unhandled”and “ Object refrence not set to an instance of an object” so I add this line

sqlCommand1 = ("INSERT INTO STUDENT (S_ID,S_NAME,S_ADDRESS,S_PHONE) VALUES (@.S_ID,@.S_NAME,@.S_ADDRESS,@.S_PHONE)" ,sqlConnection1);

Then it gave me some stupid error. By the way it didn’t make a new object of SqlCommand although I tried ….

So can u help me to solve my problem ? Thank you

the first thing i noticed is "INSERT INTO SUDENT (" +

Spelling mistake

|||Hi,

could you please send your whole code. As of now it seems that you did not initialize the DataAdapter object.
