Event code: 4005

Posted By:      Posted Date: October 18, 2010    Points: 0   Category :ASP.Net

Hy Guys,
something weird is happening! is a couple of days that my users are experincing a "logging out" isses, the error message is:

Event code: 4005
Event message: Forms authentication failed for the request. Reason: The ticket supplied was invalid.

Here the data:

1. the website is running on 3 server behind a load balancer
2. yes, machine key is the same all across thw websites, because the configuration is shared and all servers are pointing to the same folder on a NAS, this is the key:

<machineKey decryption="AES" decryptionKey=" ... snipped for security reasons ... " validation="SHA1" validationKey=" ... snipped for security reasons ..." />

3. I created the keys using an console app as suggested here: http://msdn.microsoft.com/en-us/library/ff649308.aspx#paght000007_webfarmdeploymentconsiderations
4. the form auth config is

    <authentication mode="Forms">
      <forms loginUrl="SignIn.aspx" timeout="525960" />

5. the time on the servers is in sync

... Any other suggestions?

Creating Event Handler in Code behind


Hi, so I have a control that is created in the code behind and generates fine but I can't figure out how to create an event handler for it.  I've found plenty of examples for it in C sharp, but none of them seem to apply to VB.  What I want to do is essentially this:

myDropDownList.SelectedIndexChanged = "Event to do here"

but it doesn't seem to work for me.

Any suggestions are appreciated.

Infopath button click event in custom workflow code.

Can you help me.




Infopath Changed Event code triggering in preview but not in web filler.

Hi there, I've written some code for a changed event hookup on a field in infopath 2010. The form is for submission to a sharepoint 2010 forms library. What the code does is fill in a specific value into a field depending on the selected value from a combo-box elsewhere on the form. When i preview this in Infopath 2010 it works perfectly but when i fill out the form through the web interface it simply does nothing. I've got another piece of code which executes on load and this works perfectly in both the preview and the web filler. What it does is just set the value of a field when the form loads. Here is the code, could someone tell me what i'm doing wrong? public void InternalStartup() { EventManager.XmlEvents["/my:myFields/my:service_level"].Changed += new XmlChangedEventHandler(service_level_Changed); EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading); } public void service_level_Changed(object sender, XmlEventArgs e) { // Write your code here to change the main data source. XPathNavigator xroot = MainDataSource.CreateNavigator(); XPathNavigator serviceLevel = xroot.SelectSingleNode("/my:myFields/my:service_level",NamespaceManager); XPathNavigator xest = xroot.SelectSingleNode("/my:myFields/my:est_cost", NamespaceManager); switch (serviceLevel.Value)

How to implement handle externl event activity by my code?...

As a programmer, I write some code to practice wwf, and I have implemented the **call external activity** by using reflection. 1. Firstly, define a xml document that contain a plugin detail: <xml version="1.0" encoding="utf-8" > 2.Secondly, call the external method by reflection in some codes: Assembly assembly = Assembly.Load(assemblyName); Type myInterface = assembly.GetType(interfaceName); Type myClassType = null; foreach (Type t in assembly.GetTypes()) { if (myInterface.IsAssignableFrom(t) && t.IsClass) { myClassType = t; break; } } MethodInfo methodInfo = myClassType.GetMethod(method); object instance = Activator.CreateInstance(myClassType); object result = methodInfo.Invoke(instance, userData); But when I implement the handle external event pattern, i can't finish it by using reflection directly, then i want to hookup delegate, still faild. It seems that the mothod **addService(service)** do somethings inside the wf side. Could I still implement it by use reflection? Actualy, I don't know the detail about when the host client raise an event, how wf side can recieve this action. it seemed that this is the key for my question... Thanks ligong

Running code after site definition site creation in a event receiver or feature receiver

Hi guys I've got a site definition which is pretty much based on STS.This is it's own sharepoint project. Let's call this project SiteDefProj. Next in another SharePoint project (same solution though). Let's call this CustomListProject. In this project I've got a feature which provisions a bunch of lists based on custom content types - this feature is a site scoped. Let's call this feature: CustomListInstances. I have added a feature receiver to this feature to execute some custom code on the lists themselves (under feature activated) In my ONET.XML (part of the SiteDefProj) I have CustomListInstances feature ID as part of my <sitefeatures>. When I do a create site I can actually step through the code and see it actually being executed but after the site is created the list instances are created but it's like the code never run or did anything. The weird part is that stepping through the code while creating a site collection using my SiteDefProj the code runs great with no errors. All lists are there and the code runs smooth. If I manually create a STS site and activate my feature everything works and the code does actually run and the effects are visible after the feature is created. Again I can actually step through it in debug. My suspicion is that there's some sort of a race condition in the CREATE SITE functionality where maybe the web or site collection hol

adding onload event from code behind for Google Maps

Code in an event handler not working when used with system reflection.

Hi, I am presently writing an application that uses an MDI form with a ToolStrip on it. I have the need to build the menu items dynamically using an XML file. The format of the XML file is as follows: <ContextMenu EventHandlerHost="vFrmPDUsetup"> <!-- These styles will be applied to the menu items. Individual menu item styles can be override by defining as an attibute to the specific menu item, see below --> <Style> <MenuStripBackColour>Transparent</MenuStripBackColour> <BackColour></BackColour> <ForeColour>Chartreuse</ForeColour> <BackImage></BackImage> <!-- Must exist in Images folder --> <FontName>Tahoma</FontName> <FontSize>10</FontSize> <FontStyle>Bold</FontStyle> </Style> <!-- Attributes: Key = Resource Key name in resource file Image = image to display before text, image must exist in Images folder BackImage = background image, image must exist in Images folder BackColour = background colour as colour name ForeColour = foreground colour as colour name FontSize = size of font as value Seperator = add a menu seperator OnClick = click event pointing to the event handler method which must be defined as the MenuItem_ + <attibute value> &

Event Handler returning unexpected Error Code

How can i safe value of variables in javascript code in PostBack event?


Hi Experts.

I need to define some Boolean variables in my javascript code and use them  when  the any onfocusout methods of controls  is fired. Like this:


            Var is_ValidateTextBox1 = false;

            Var is_ValidateTextBox2 = false;

            Var is_ValidateTextBox3 = false;

Function focusout_TextBox1()

{ValidateTextBox1 = true; }


When onfocusout of TextBox1 is fire, I want to set  " is_ValidationTextBox1=true;".  But when the post back is fired from the form, the variable reset to false because the line of defining the "Var is_ValidateTextBox1 = false;" is run again in post back!

Now how can I to solve this problem? How can i safe value of variables in javascript code in PostBack event?

MVVM how to move event handler from code behind to ViewModel


First of all I'm fairly new to WPF and MVVM. For learning purposes I created a very simple MVVM test app similar to the one demonstrated here: http://windowsclient.net/learn/video.aspx?v=314683

I am trying to find out how to work with events in the MVVM pattern. To work with events in the xaml code behind is simple. But how to move the code to the ViewModel?

In the xaml I have:

    <StackPanel Background="{Binding BackgroundBrush}">
        <ItemsControl ItemsSource="{Binding AllEmployees}">
                    <StackPanel Orientation="Horizontal">
                        <TextBox Width="100" Text="{Binding FirstName}" />
                        <TextBox Width="100&q

Run Code/Fire Event After First Event Finishes

I have a form with an ActiveX control on it. When the disconnect event of the OCX runs, I want to close the form. The problem is, if I call the close command from within the disconnect event, I get an access violation as the form/control is disposed of when the OCX event finishes up.

OCX Disconnect Event
Custom EventHandler for OCX Disconnect Event
Clean up all connections and close form
Form Close Event
Form is closed and all controls are disposed of
Exception thrown as the parent form no longer exists

I just need to make the Clean up all connections and close form function run after OCX Disconnect Event, but I don't know how or if its possible. Any help or work arounds would be appreciated. Currently, my only work around is basically to leave the parent form open and have the user close it.

If it helps any, this form is a child of a master MDI form.
