Error running unit tests under MbUnit (Gallio)

In this example i am going to demonstrate how to display running total in footer row or footer template of GridView in ASP.NET using C# and VB.NET. This method works with paging enabled gridview as well.

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!

 

 

 

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 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)

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.
