Asp.net - Reference Page Class From A Code Folder?
Oct 14, 2011
I have an ASP.NET website written in VB.NET and trying to add MVC to it.
I managed to add controllers (to CS_Code folder) and make them running. However, I have to use some code from aspnet pages.
When I try to call method from page I ma having compile time error
public CustomerFrontend.DefaultForm DefaultForm { get; set; }
Error:
The type or namespace name 'DefaultForm' could not be found (are you missing a using directive or an assembly reference?)
Page directive definition which proves than namespace is correct:
<%@ Page Language="vb" ValidateRequest="false"
EnableViewState="False"
AutoEventWireup="false"
Inherits="CustomerFrontend.DefaultForm"
CodeFile="DefaultForm.aspx.vb" %>

I have a very simple class that is located within my App_Code folder in my VS2008 web application project. I am trying to instantiate an instance of this class from my code-behind file. Intellisense does not seem to be seeing my class and I am not sure why. I am using VB.NET which I am admittedly not that familiar with as compared to C#. Perhaps I am missing something. I would bet it has something to do with something I am missing in VB.NET.Here is my simple class (for testing):

What used to be C:Documents and SettingsAll UsersApplication Data is now Win7 as C:UsersPublicPublic Documents or similar..This folder is not part of the Environment.SpecialFolders list. Is there another way to expose the above Public folder?I'm hoping you can programatically use that location for non virtualized read/write/alluser files.

I have a 'property management class' that contains several functions and properties. I have several other classes that use the 'management class' as a property to derive the value of several of its other properties.Is there a way for me to reference the outer class from the 'management class' functions without having to pass it as a parameter? I ask because several different classes can have this 'management class' as a property and am having a hard time typing the parameter.

If we are within the derived class then ofcource we can use MyBase keyword to access base class's object reference . That's fine , how can we take that base class's object reference outside that derived class's definition.My following code will explain what i want . Actually that is giving error right now, but it is explaining my requirement .
Public Class Base
Public x As String
End Class
[code]....
Actually there is error in ReadOnly Property BaseReference's Getter . Error is "Error 1 'MyBase' must be followed by '.' and an identifier. " how can i get base class object reference in Main method ?

I need to create a new instance of a class that needs a member of the calling class. But i can't pass a reference to the calling class through the constructor.The solution i am looking for is something like this:
Public Class ChildClass
Public Sub New(args)
_MyMember = GetMemberFromCallingClass()
[code]....
I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass.

I am creating a notes software. This is just a simple application that will show the data from the database which are Notes_Title, Due_Date, Priority. I display the data with datagridview. I also added a checkbox for each row to the datagridview to mark as check if the Notes_title is already done. In displaying the data, I need to display only a 5 data in a row.So, I create a another CLASS that will only show 5 rows per page. But the PROBLEM is, if I mark the checkbox as check in the first page then if I turn it to the next page the checkbox in the first page that mark as check will be uncheck if I turn it back to the first page. The mark check in the checkbox will mark as uncheck if I turn the page. How can I make it mark as check even if I turn the pages? And How can I save the data row as done if I check

I have an ASP.NET 3.5 page with some AJAX, some Validators and some business-rule validation done in the code-behind page (VB.NET).
The Validators set focus to the 'offending' control when an error is detected.
When a business rule is violated, I used the following code to generate some javascript "on the fly" and execute it to simulate the Winforms "MessageBox.Show" functionality:
Sub DisplayMessages()
Dim lblError As New Label
lblError.Text = "<script language='javascript'>" & Environment.NewLine & "window.alert('"
[Code]....
At the end of the "btnSave.Click" code, if everything went ok, calling that subroutine.
What I get is the page scrolling to the top and then back to where it was when the Save button was clicked.
For various reasons, 'MaintainScrollPositionOnPostback="True"' is in the Page directives at the top of the .aspx code. What I'd really like is to make that FALSE for just a moment so that the page resets at the top - again, only if everything is ok and only for this button (there are other buttons on the page that require the page to keep it's scroll position).

i was just wondering if in Visual Studio there was a way to put all the referenced DLL files in a separate folder for when you build the project? I'm talking about when you build the project and go in Bin/Release or Debug, i have the exe file along with all the DLL files in the same folder and would like to clean it up and get the dlls in a separate resource folder or something like that.

I'm converting a VB6 app to vb.net.The code creates objects using the CallbyName function with the classes name & and method being read from a database.I want to rewrite the classes in vb.net and have the same behaviour as I read in the name of an object from the database, instantiate it, and call one of it's methods.I don't know ahead of time what the names of the classes will be, so I can't make a reference to them in my project.
