C# - Page Methods Throwing Undefined?
Dec 1, 2010
I am trying to use page methods to call a function and I am getting a "PageMethods is undefinded" error. I have used them before whilst using C# but not VB so I'm wondering if my syntax is wrong as all examples I can find are C#. I am also wondering if it's because my scriptmanager is on the master page?
I've read about this error everywhere but everything I have appears to be correct!
My code:
Part of Master Page
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" EnablePageMethods="true" >
[Code]....

I have a project written in MVC2 and VB.NET. I use a lot of htmlhelper extension methods,and I have them all in a public module. They work just fine, and I can compile and run my project. I reference the namespace they are in with this:<%@ Import Namespace="MyProject.WebUI.Extensions" %>So, again, they work great, my project runs and compiles without a hitch.The problem is that each one of these extension methods is shown as an error:
Error 33 'TabbedMenu' is not a member of 'System.Web.Mvc.HtmlHelper(Of Object)'. C:ProjectsMyProjectMyProject.WebUIViewsSharedSite.Master 23 21 MyProject.WebUI

Several of my overriden Equals methods have started throwing Invalid Cast Exceptions -
Unable to cast object of type 'System.DBNull' to type Common.ResolveUser'.
This occurs when binding List (of T) (where T is of type ResolveUser in this case) to a combo.
Equals Method:
Public Overrides Function Equals(ByVal obj As Object) As Boolean
Dim i As ResolveUser = CType(obj, ResolveUser)
If i.UniqueResolveID = UniqueResolveID Then Return True

There is a site that I go to that has a website chat thats located at the bottom of every page. It allows you to talk to specific people while you're online and they're online.
Sometimes when I get into a good conversation I don't want to end it. I still have other things to do though.I wanted to make a small window that I can just drag around that will allow me to chat with people easier.
I've set up pretty much everything in this program except the actual retrieving of the information from the site and the replying to the chat. I know I could do this (I've done similar things in the past) by putting an invisible webbrowser object off to the side and just run my stuff through there. But I think thats kind of sloppy.
I've read in some of my classes and books and have learned how to make simple web requests that return the results. In its case, I had to return definitions from google. I tried this on a recent project but found that it didn't the permission to access any kind of secured account whether it was logged in or not because it was "unsafe".
Does anybody know how to access a page thats been logged into through IE but without needing the sloppy methods I mentioned earlier?

This is the original code in c#

Does anyone has an idea what i should change to let it work and let my UserRepository use the methods in RepositoryBase while implementing the IUserRepository?

I am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?

These objects are derived from System.IO. I am running Visual Studio 2008. When I go to the VB object browser, I see System.IO.Log, but do not see System.IO. When I try to use Streamreander and Streamwriter in my VB programs I get an undefined error.

I am working on a VB NET project and had the strangest thing happen.I created a class file(just like a dozen or so I have already created). I wrote in the code to access it. The autocomplete found the class, filled it in and colored it blue, just as it should.But, when I run the app, I get a type is undefined error.
There is nothing in the class yet. And there is really no code to post..it is as straight forward as I described.I tried restarting VS; Deleting and recreating the class; Deleting the class and creating a new one with a different name.
Is there something in the VB NET configuration I can check to see if it is not being added somewhere?
I found the problem. I have 2 projects in one solution. They both share some classes that were trying to use my new classes. When I hit F5, both projects are compiled, and since I hadn't shared the classes with the second project, it errored.
So, now my question is changed; How do I specify to only build the specified Startup Project when debugging?

Alright, so I've got my program and it works, but I have to pump out updates every once in a while. If I can get it so the code will let me have my text file with any number of lines for my array, then I can simply send out a text file and update done.So here's what my code does:
Define a record of arrays, two items, a unicode string (Japanese/Korean text) and then an English translation for the text.I read in the file, it's one item per line, unicode string and then the translation.I have it preset with a defined upper bound for my array, but if I just took out the define and leave the upper bound as limitless, then it would work if I just updated the text file. Problem is, I don't know how to do it with stream.reader (I think that's what it is) because I learned a different way in school. I want to do something like Do While Not EOF with this, and loop it reading lines from the file.
Would it work if I change the array to no upper bound and then simply use Do While Not EOF with stream reader?

I have a Javascript function for my select box, but after I included runat="server" to it, the script debugger highlights on this line below:
' for (i = 0; i < sourceTo.options.length; i++) { ' and says:

I included it because I wanted to loop through it in code behind and perform some other stuffs?

Working around an issue where my jquery datepicker does not display after postback within an update panel.
The textbox (trigger) for the calendar is contained within a control, which is contained within an update panel.I found an article assisting with this issue, and it informed me to do the following
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim tScript As String = "$(function(){ Sys.WebForms.PageRequestManager.getInstance().add_endRequest(ShowDatePicker); });"
Page.ClientScript.RegisterStartupScript(Me.GetType(), "async_" & Me.txtAquisition.ClientID, tScript, True)
Then on the ascx I have
[Code]...
Am I approaching this in the correct manner? Any other suggestions to ensure my datepicker remains usable within the update panel?Thinking this may be due to the fact that I have the controls nested within an update panel... several of them in fact.

I am currently attempting to create a VB.Net script that pulls up information on installed printers. I am using Visual Studio 2010 SP1, and as my target program needs to run on older machines, is currently built using .Net 3.5.Looking online, there are several methods on how to do this, one from url...the code is supposed to use System.Management as you can see. However, after importing System.Management, Visual Studio throws an error and states that ObjectQuery, ManagementObjectSearcher, and ManagementObject are not defined.a quick look at the MSDN forums shows that ObjectQuery is a class of .Net 4, 3.5, 3.0 and 2.I figured the error might be because I didn't have the .Net 3.5 SDK installed, so I installed the .Net 3.5 SP1 SDK to no avail.just to make clear, I am importing System.Management at the top "Imports System.Management"

I thought at first that because during testing GetFormsByStatus() returns 0 results maybe that was causing problems, but it doesn't make sense that Except() wouldn't work if the provided list had 0 items.

I have the following code:
Public Shared Function GetAvailableManufacturers() As List(Of Manufacturer)
'first get all the live orders and extract their mfrs'
Dim sos As List(Of OrderForm) = GetFormsByStatus(StockStatus.Building)
Dim unavailableMfrs As New List(Of Manufacturer)
[code]....
My idea to get available manufacturers was to get a list of all the manufacturers in my open forms, then get a list of all manufacturers and exclude all the manufacturers in the first list, illustrated like so (pseudo):
List A: {1,2,3,4,5,6,7,8,9,10}
List B: {5,7,10}
Result: {1,2,3,4,6,8,9}
I have set up my Manufacturer class according to this article so that it can be compared, but I'm still getting this error:
Unable to cast object of type '<ExceptIterator>d__92'1[csCore.Manufacturer]' to type 'System.Collections.Generic.List'1[csCore.Manufacturer]'.
I thought at first that because during testing GetFormsByStatus() returns 0 results maybe that was causing problems, but it doesn't make sense that Except() wouldn't work if the provided list had 0 items.
