SQL Connection String to SQL Server Database

Question

I am having trouble trying to get my connection string to connect to my SQL Database file here is my code

    Dim myConn As SqlConnection

    Dim cmd As SqlCommand

    Dim sqlstring as string


    'Difines what database i would like to use '
    myConn = New SqlConnection("Data Source=SHAREPOINT-TEST;AttachDbFilename=\\sharepoint-test\SPD\MSSQL\Data\ProblemsAndActions.mdf")
    'Opens the connection to the database'
    myConn.Open()
    'inserts into database what table and what information relevant to what variable line in table Master'
    sqlstring = "INSERT INTO Master (Id, Raised_By, Customer, Complainant_Details, Product_Code_Affected, Description_Of_Product, Qty_Affected, Batch_Affected, End_Customer, Order_Number, Consignment_Number, Details_Of_Complaint, Severity_Rating) VALUES ('" + L1 + "','" + L2 + "','" + L3 + "','" + L4 + "','" + L5 + "','" + L6 + "','" + L7 + "','" + L8 + "','" + L9 + "','" + L10 + "','" + L11 + "','" + L12 + "','" + L13 + "')"
    cmd = New SqlCommand(sqlstring, myConn) 'comands to insert the above line ^'
    cmd.ExecuteNonQuery() 'execute the command'
    myConn.Close() 'closes connection to database'

Error I keep getting is:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

My SQL Server instance Name is SHAREPOINT-TEST\SHAREPOINTTESTSQ

Ports open in the firewall? Server set up to allow remote connections? — Allan S. Hansen

Assuming you can execute that SQL using SSMS, I suspect that tour connection string is incorrect. Try:

myConn = New SqlConnection("Server=SHAREPOINT-TEST\SHAREPOINTTESTSQ;Database=ProblemsAndActions;User Id=myUsername; Password=myPassword;")
