master page error

I think in many time developer need this event, which is not provided by any browser and it is not captured by any javascript event.In this Article you see how you capture this event and how you force the browser to load the page from server.

I'm trying to figure out how I can get around an error I get when multiple users are accessing different my site. I'm getting an error:

there is already an open datareader associated with this connection which must be closed first

It's not the same query everytime but I recently triggered it on this statement:

Dim adapterSavedState As New SQLDataAdapter("SELECT SavedStateContactView, SavedStatePropertyView, SavedStateTransView, SavedStateCompanyView FROM WebusersProfiles WHERE ContactID = '" & Session("ContactID") & "'", myConnection)
    Dim dtSavedState As New DataTable()
    adapterSavedState.Fill(dtSavedState)
         Dim rowSavedState As DataRow
         For Each rowSavedState In dtSavedState.Rows
             If Request.QueryString("View") = "Contact" Then
                SavedState = rowSavedState("SavedStateContactView").ToString()
            Else If Request.QueryString("View") = "Property" Then
                SavedState = rowSavedState("SavedStatePropertyView").ToString()
            Else If Request.QueryString("View") = "Trans" Then
                SavedState = rowSavedState("SavedStateTransView").ToString()
            Else If Request.QueryString("View") = "Company" Then
                SavedState = rowSavedState("SavedStateCompanyView").ToString()
            End If
         Next rowSavedState

I define my connection in my basepage

    Public Dim MyConnection As SqlConnection
    Public Shared Dim strSite As String = "dev"
        
    Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
        myConnection = New SqlConnection("server=xxxx;database=xxxxx;User ID=xxxxx;Password=xxxxx;")

Where is my issue and how can I overcome it? This is a .net 1.1 site so MARS I know is not available...

Have a project where I need to access a RSS feed.   The issue is this RSS feed, you need to be logged in as a user.   They have a simple web form (login + password).   How do I?

1) Post a web form with my login and password

2) Maintaining Session (w/successful login), do an additiional GET to retrieve the RSS feed.

I am doing this in an ASP.Net page so it all happens server side in VB.Net

hi for all

please i want calculate number of refresh per page how can i do that 

Hi All,

i have a program in vb.net..i use the webrequest to post the data to another page (http://localpost/posReceived.aspx), and use the webResponse to get the back the response from the remote page.

When i run this program, it returned error "The remote server returned an error: (403) Forbidden.". I have no idea on this. Coz my aspx page and posReceived.aspx are placed in the same server and same directory. I supposed it should be worked without any security concerns.

Can anyone help me to solve it. Thanks a lot!

I have created a sample Web App. for creating dynamic controls. It worked fine when I originally created it, however after closing the solution and opening a couple days later this is what happens. Any ideas why?

 

Error Creating Control - ScriptManager1, Oject Reference not set to an instance of an object. 

Error Creating Control - Button1, Oject Reference not set to an instance of an object.

Hello,

I am facing this error 

Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.

Parameter name: element

while using Ajaxtoolkit ModelPopupextender with listview, actually I am retriving image from database to the listview in VS 2008. 

Can anyone please help me out of this..

I am having some problem with Jquery validation.

In my application i am using jquery validation plugin..I am using Updatepanels and i am validating using

Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(ValidateMyForm);

and ValidateMyform will validate on each button click...

var objPost = args.get_postBackElement();
    if (objPost === null || objPost === undefined) return;
    if (objPost.type == 'submit') {
      
        if (objPost.id == 'btnUpdate') {
             var isValid = $('#form1').validate({
                errorClass: 'error',
               
             },
                invalidHandler: function (e, validator) {
                    var errors = validator.numberOfInvalids();
                    if (errors) {
                        //custom error message
                    }
              }    

            }).form();

            if (!isValid) {
                CancelPostback(sender, args);
            } else {
                $('form1').submit();
                $('#form1').get(0).reset();

}

Here I want to get back the page to normal stage(like after a full page postback)...even though after async postback the validation is still active...it should not get back to normal and its throwing errors if i enter something wrong...this is because the page is not fully refreshed on asyc postbacks...I just want get the like the normal after each asyc post back...

I tried using submit and reset to reset the page but its became to normal..the validation is still active...I have no idea what to do..

i am very new to jquery and i am facing many problems...so please kindly help me out in this...
