Connecting to a remote SQL database

Hey, not sure where to post it on here but sorry if it's in the wrong spot.
Anyway, I am trying to connect to a SQL database through a visual basic app.
I can't even get it to connect, any idea on what could be wrong?
It just hangs and then after a minute closes.
Here is what I have,

Code:

---

        Dim oSqlConn As New SqlConnection
        oSqlConn.ConnectionString =
        "Data Source=118.139.179.54;" & _
        "Initial Catalog=gunderak;" & _
        "User ID=gunderak;" & _
        "Password=XXXXXXXX"
        oSqlConn.Open()

---

Cheers.

Also does anyone have any idea how to actually do query's such as insert or drop etc?
