Sub Page_Load(ByVal Sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not Page.IsPostBack Then
Dim SQLconn As New SqlConnection("Server=(local)\SQLExpress;Initial Catalog=Test;Integrated Security=True")
SQLconn.Open()
Dim Query As String = "SELECT rawvalue FROM Device1 WHERE device = 'Channel1'"
Dim SelectCmd As New SqlCommand(Query, SQLconn)
Dim result As Boolean
SQLconn.Open()
Dim myDataReader As SqlDataReader
myDataReader = SelectCmd.ExecuteReader()
result = myDataReader.GetBoolean(0)
SQLconn.Close()
ChangeButton(result)
End If
End Sub
Sub ChangeButton(ByVal Status As Boolean)
If Status Then
OnOff.Text = "Press to Close"
Label1.Text = "ON"
Label1.BackColor = Drawing.Color.Green
Else
OnOff.Text = "Press To Open"
Label1.Text = "OFF"
Label1.BackColor = Drawing.Color.Red
End If
End Sub
I have this code to change some properties of a label and a button. The problem is that I get and error while debbugging this in Visual Web Developer.
The error is:
"The connection was not closed. The connection's current state is open."
The problem is in line 21 "SQLconn.Open()"
Stack Trace:
[InvalidOperationException: The connection was not closed. The connection's current state is open.]

You have two calls to Open().

Yes. Thank you.
I deleted "Handles MyBase.Load" and I don't get the error message now.
The problem now is that I don't get any values in my Button and Label controls.
I mean the Boolean value passes to ChangeButton procedure that should initialize the controls.
QLconn.Open()
Dim myDataReader As SqlDataReader
myDataReader = SelectCmd.ExecuteReader()
myDataReader.Read()
result = myDataReader.GetBoolean(0)
myDataReader.Close()
SQLconn.Close()
ChangeButton(result)
Sub ChangeButton(ByVal Status As Boolean)
If Status Then
OnOff.Text = "Press to Close"
Label1.Text = "ON"
Label1.BackColor = Drawing.Color.Green
Else
OnOff.Text = "Press To Open"
Label1.Text = "OFF"
Label1.BackColor = Drawing.Color.Red
End If
End Sub

Why would you delete the handle from the event??
The only problem you had was that you were opening the connection twice...
|
|
|
|
|
Man. Thank you again!!!!!!
I'm so stupid and blind. I put the handle and it works perfect.
If you have the time can you please explain me why this handle is needed?

You can name your page load sub to be whatever you like (as long as it has the right method signature). The handles keyword tells the system which function to fun on page load...
If you want some more info, read up on events within asp.net.

hi all,
I have a flash application which needs to send values to the server (here asp.net). Also the response from the server is sent again to flash.
Going through the articles i found that the method,sendandload allows two way communication between flash and asp.net.But the problem is that the values are passed to the asp.net page but the page gets loaded again and again.
Thanks in advance

Hi All!!!
I´d like to know if somebody can give any idea, cause I don't know what else to do:
Scenario:
ASP.NET GridView, linked to a Customer Object (public/private properies) through a ObjectdataSource
The Thing is that when I am doing the Update of the Grid, the Object Customer arrives with all the data to the BLL, but when I am clicking in the Delete one, the object arrives empty to the BLL.
I have debuged it, and in the "Deleting Event" of the Grid, the values for the parameters are there, but in the "Deleting Event" of the Object DataSource the values dissapear...
Can anybody give any ideas
Thanks and Regards

Each time you post back to the web server you most likely need to bind your Grid back to the datasource. I would guess you left this out when you are doing a delete. So after you do your delete logic you would need to do another objectdatasource.select and gridview.databind or datagrid.databind.
Hope that helps.

Thanks Man...
But I don't think the problem is there (I tried it now), because I can "Update", when I click in the Update Button, the the BLL the object arrives with all the new properties modified, the problem is when clicking in the Delete arrives Empty.
If I debug the the page, when the deleting event of the grid is fired I can see in the "e" var the properties and I can see how the .net creates using Activate the BLL Object. But the properties are not being assigned.
In the update event I also debug the point where the properties are assinged...

Because I was creating the GridView columns at runtime based on the schema of the Business Entity, because of that I forgot assing the DataKey property
