Attachment upload error on browser based InfoPath form

 Hi, I have window form to let user fill data, I want to alert user if close web browser before saved web form data, could anyone provide any clue?

Thanks,

Martin

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...

I'm doing an application which has already contains a master page named Master.master. And all related web forms(Webpage) are running well. But I create another master page in same application named Profile.master for some other web form(Webpage). But this time some of the related pages are running a blank page and some are generating an error that is:-

is not allowed here because it does not extend class 'System.Web.UI.Page'.

please help me to rectify this error.

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!

hey,

i've read several posts with similar but problems, but i can't find one exactly like what i am seeing.  This is probably very simple...i just can't get the exact solution.

Platform is c#, VS 2010.

I have a web form and code behind file, with scripting that works just fine.  i'm trying to move script from the code behind file into a class, to consolodate and create re-use. The basic problem is when i move the script into the class, i cannot access the webform.

error here on "this":   HyperLink hyplAlertbox = (HyperLink)this.frmEtsuHome.FindControl(codeboxID);

i know WHY it throws the error, i just don't know how to fix it.  any help is appreciated.

below is simplified code....

------------------------------------------------------------------------------------------------

New Script in Code Behind File:

namespace myhome
{
    public partial class _default : System.Web.UI.Page
    {
                    
        protected void Page_Load(object sender, EventArgs e)
        {

             new majorAlerts();
             majorAlerts.GetAlerts();
             majorAlerts.ProcessAlerts();
        }
    }
 }

-------------------------------------------------------------------------------------

Code for the Class

-------------------------------------------------------------------------------------

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;

namespace myhome
{
    public class majorAlerts
    {
        
        public static void GetAlerts()
        {
            // grab the alerts and store them in a list                     
        }

        public static void ParseAlerts(List<Alert> lAlerts)
        { 
            foreach (Alert Alert in lAlerts)
            {
                  // create codebox ID 
                codeboxID = "codebox" + index.ToString();
                // find hyperlink with ID of codeboxN cand reate an instance of it 
                HyperLink hyplAlertbox = (HyperLink)this.frmMyHome.FindControl(codeboxID);

//******************* ERROR *************************************************
// ERROR ON this in previous line.  i understand, because "this" is not the form like it is in the code behind file. 
// but i don't know how to modify "this" and make it work from class file
// **************************************************************************

 // set hyperlink URL value for alert based on alert ID
                alertURL = "http://www.blah.com";
                hyplAlertbox.NavigateUrl = alertURL;
             }
     }

I got a very long user creation form with tons of validation.  Works fine.

Now I want to "split" this form into 5, displaying each form in a set of tabs (will be using jQuery UI Tabs).

So when you start, Tab1 is enabled, the rest not.

You finish what is in Tab1, and click "Next", the part of the original long form get validated (like a normal form using client side and remote validation .....it *must* be client side.  User Requirement.)

If valid, Tab2 becomes enabled, and also the user are shown Tab2.

Once the user get to finish and reach the last tab (which will basically just have a "Submit" button) I need to post everything that was entered across the series of tabs to the server (back to the single form/model/controller the existing form works on).

Any tips / advice / samples out there will be welcome.  (However not suggestions to change the requirements....picky as hell client)

Thanks for reading....
