ASP.NET MVC database connection using a form


ASP.NET MVC database connection using a form

This might help you You don't connect the actual form itself, you connect your backend to the DB, and you connect the form to your backend. Make some sort of route to handle the form request and then connect to your database in that route, and use it to input the data to the database.

like below fixes the issue In your MDI Form create a module level variable to hold the connection:
code :
Private m_Conn as ADODB.Connection
Public Property Get CurrentConnection() as ADODB.Connection
     Set CurrentConnection = m_Conn
End Property
Dim oConn As ADODB.Connection

Set oConn = MainForm.CurrentConnection
Does every Form in c#.net needs a new connection to be established with sql database?

Hope that helps No, I'd say that in general, for a thick (single-threaded) client, you probably want only one connection open (probably for the lifetime of the client).
You can keep the parameterless constructor for Form2 (which will be needed for the VS designer to continue to work), but you can create a second constructor for Form2 that is passed the open connection and continues to work with it, e.g.:
code :
public Form2()
{
    InitializeComponent();
}
private SqlConnection _conn;
public Form2(SqlConnection conn)
    : this()
{
    _conn = conn;
}

Hope this helps To literally answer your question: your getConnection method is a public static method so you can call this from anywhere. Just call ConnectionManager.getConnection() where-ever you need that connection.

To fix this issue You have to substitute the username and password in your DSN with the form data:
code :
conn = ibm_db.connect("DATABASE=WDLAB; HOSTNAME=127.0.0.1; PORT=10000; PROTOCOL=TCPIP;UID={};PWD={};".format(USER_ID, USER_PASS), "", "")
