Error in viewing InfoPath forms (mobile version)

I utilized forms authentication as provided by ASP.NET engine. At first, everything worked well until there was a need to manually sign out current user. Quick look into MSDN documentation revealed SignOut() method of FormsAuthentication class. The documentation promised that this method signs out the user and redirects the client to login page. Considering the fact that I did not care about redirect (Flex application was running on the client side, so that redirection did not have any effect), I was hoping that the method would still perform desired effect and "de-authenticate" (I know, I know, that is not even a word) current user. At first, it seemed to work, but debugging revealed that even though this method removed authentication cookie, it did not sign out the user. User's identity was still marked as authenticated and subsequent calls to the Http handler would be considered authenticated. Furthermore, the session object was still valid, so that existing session information was still available. Quick look into MSDN revealed Session.Abandon() method, which would destroy session object upon execution. However, even though the session object was destroyed, client calls to ASP.NET web application were still considered authenticated. It was time to search the web to see if other developers faced the same issue.

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!

 

 

 

Ok..my last in a series of questions tonight....

Got a form using a strongly typed view.  The viewmodel have a nested type, which mostly are not displayed on the form.  (Say a "person" model with an "address" nested model.) 

Note: This is just a simplified example....(and this have not been started yet, so I'm open to alternative suggestions, as long I can fit it into th user requirements)

On the form, I have a label, showing the city of the user's address.  Of course this will not show anyting when you create a new person.

On the form is a button "Create Address".  This will popup a modal form (strongly typed...."address").  You enter an address (street, select country, etc) and click save.

Now....This "address model" must become the value of the "main" form's "person" model.

At the same time, the "city" label of the main form must show the "city" member of the "address" nested model.

This should all happen client-side (dang..this client with their "client-side" requirements..why not just get a desktop app build then?)

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?

		var methodName = "add";
		var useGet = false ;
		var xValue = $get("cboScenario").value;
//		var yValue = "Scenario:8";
//		var zValue = "";
		alert("xValue");
		var params = {x: xValue};
		var userContext = $get ("result");
		var webServiceProxy = new Sys.Net.WebServiceProxy ();
		webServiceProxy .set_timeout(0);
		request = webServiceProxy ._invoke(servicePath ,methodName ,useGet ,params ,onSuccess, onFailure, userContext );
		}
		function onSuccess(result, userContext, methodName)
		
		{
		userContext .innerHtML = "<b><u>" + result + "</b></u>"
		
		
		}
		
		function onFailure(result, userContext, methodName)
		{
		    alert('Ravi');

 [WebMethod ]
    public DataSet add(string x)
    {

//code for populating using x
return dataset;

how to overcome this problem?

I have got this script from http://flowplayer.org/tools/demos/overlay/modal-dialog.html and using this overlay to display errors in my application. But when i call this script from code behind I get "Operation Aborted" in IE although it works perfectly in FireFox. Here is the code

Here is the Code behind where i am calling "triggeroverlay" javascript function to display error to the user.

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

        }

        protected void Button1_Click1(object sender, EventArgs e)
        {
         ClientScript.RegisterStartupScript(this.GetType(), "throwError", "<script>triggeroverlay();</script>");
        }
    }
}

I was reading this article about the same thing but didn't get it properly. Please help and give example where i am wrong and how to make it work.
