Tracking PageMethod Failure

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :ASP.Net

Hi All,

  I have a webmethod that I call from javascript. It succeeds most of the time but at certain times it fails. The webmethod writes some data to a text file. I do not see an error generated neither on the client side nor on the server side when it fails. i was wondering if I could be able to track its failure and have it  execute a couple of times in a loop until it succeeds. My code looks like this trying to track its failure but the code is not returning any alerts. Please help !!!

The fileWrite function triggers upon the firing of the window.onbeforeunload event.


function FileWrite() {
           PageMethods.WriteToFile(OnSucceeded, OnFailed);

       // Callback function invoked on successful
       // completion of the page method.
       function OnSucceeded(result, userContext, methodName) {

Customize failure text for login control


Hi all,

I would like to show the failure text in a client-side alert box for login control in c#. Please help me if there is an easy way to convert it from vb.net to c#.net. Thanks a lot!

Protected Sub Login1_LoginError(ByVal sender As Object, ByVal e As System.EventArgs) Handles Login1.LoginError
'Display the failure message in a client-side alert box
ClientScript.RegisterStartupScript(Me.GetType(), "LoginError", _
String.Format("alert('{0}');", Login1.FailureText.Replace("'", "\'")), True)

 End Sub

 Converted, but it doesn't work.

protected void Login1_LoginError(object sender, System.EventArgs e)
    //Display the failure message in a client-side alert box
    ClientScript.RegisterStartupScript(this.GetType(), "LoginError", string.Format("alert('{0}');", Login1.FailureText.Replace("'", "\\'")), true);

Failure to reliably iterate through all elements of a COM Collection from C# .NET 4.0

In C#, .NET 4.0, I am making a call to a COM DLL to return a collection object. A foreach loop steps through each element of the collection. In the loop, a new .NET object is created for each element of the COM collection. The new object is added to a new .NET collection. This works fine in the development environment. In a deployed system, is works correctly most (about 90%) of the time.  However, sometimes (about 5% of the time) the foreach loop finds no items in the COM collection. Other times (also about 5%), it finds the first 2 or 3 or ... N items.  Somehow, the enumeration interface exposed by the COM object is failing. Here is a code snippet from the COM Object, which is called NameList.  NOTE that the VB6 cls file was opened in a text editor to show the class and method attributes. VERSION 1.0 CLASS BEGIN MultiUse = -1 'True Persistable = 0 'NotPersistable DataBindingBehavior = 0 'vbNone DataSourceBehavior = 0 'vbNone MTSTransactionMode = 0 'NotAnMTSObject END Attribute VB_Name = "NameList" Attribute VB_GlobalNameSpace = False Attribute VB_Creatable = True Attribute VB_PredeclaredId = False Attribute VB_Exposed = True Attribute VB_Ext_KEY = "SavedWithClassBuilder6" ,"Yes" Attribute VB_Ext_KEY = "Top_Level" ,"Yes" Option Explicit Private mCol As Collection ' <snip> Only code rela
