Anyone do anything in .NET 2005?
Got a snippet of code that is supposed to save to a database. It doesn't. I'll be damned if I can figure it out. Written in VB.
--- Code: --- 'save to the database
conn = New SqlConnection
conn.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\cyberhack.mdf;Integrated Security=True;User Instance=True"
Dim sCmdText As String = "INSERT INTO Game ([GameName], [GameDate], [GameTime]) VALUES (@GameName, @Date, @Time)"
Dim cmd As New SqlCommand(sCmdText, conn)
Dim iRow As Integer
cmd.Parameters.Add("@GameName", SqlDbType.VarChar, 50)
cmd.Parameters.Add("@Date", SqlDbType.DateTime)
cmd.Parameters.Add("@Time", SqlDbType.DateTime)
cmd.Parameters("@GameName").Value = txtName.Text
cmd.Parameters("@Date").Value = "01/01/2068"
cmd.Parameters("@Time").Value = "12:00"
MsgBox(conn.ConnectionString)
'cmd.CommandText = "cyberhack.dbo.GameInsert @GameName, @Date, @Time"
cmd.CommandType = CommandType.Text
Try
cmd.Connection = conn
conn.Open()
cmd.Prepare()
iRow = cmd.ExecuteNonQuery
MsgBox(iRow)
conn.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
--- End code ---
iRow has a value of 1, which means the call returned 1 row like it should. It does not throw any exceptions.

Were you biting your lip while you wrote it? Sometimes that helps.

I think I was cussing the computer when I was trying to debug it...
RoguePhoenix:
A nice big rubber mallet is usually helpful. We keep one in our cube for the parts database management server. It usually works pretty well too!
And if we're good lil boys and santa is ever so nice this year we might even be able to office space it when the new system comes in MWUHAHAHHAHA
Randy:
Not sure if it makes a difference, but I usually have the connection opened before trying to create a comand from it...
ie do
--- Code: ---conn.open()
--- End code ---
before
--- Code: ---Dim cmd As New SqlCommand(sCmdText, conn)
--- End code ---
But this assumes that your connect string is working. Are you able to perform a select using that connect string?
I generally keep the connection open (unless doing asp.net) as it works a little faster using connection pooling.
I also tend to assemple the sql string rather than using parameters (they get real annoying sometimes
Then again, I'm only using .net 2003 and Access...
