I've tried searching... a lot for the answer, but as I'm not too sure what exactly I'm trying to do I can't seem to find anything. I'm trying to write a dll in order to handle errors thrown from a vb.net app. In the dll I need several forms (I'm not totally sure if they can have forms - I'm a bit of a newbie when it comes to dll's) for which the user can type in their message about the error and submit it.
I want to created a nested class that can only be visible to and instantiated from the parent class.But I also want to be able to use an instance of the nested class through a public variable of the parent class.I tried making the nested class private, or making the nested class' constructor private, but it won't compile.Is it possible to do this in .NET?
Within my application i have a PUBLIC customer class...
Public Class Customer Public Name As String Public Surname As String End Class
Then i decided to use LINQ to SQL within my application.After adding the MyDatabase.dbml class, errors showed up since LINQ creates public properties too
<Column(Storage:="_Name", DbType:="NVarChar(50) NOT NULL", CanBeNull:=false)> _ Public Property Name() As String Get Return Me._Name End Get
Here are some errors..'Name' is already declared as 'Public Name As String' in this class.'SurName' is already declared as 'Public SurName As String' in this class.
Ok. Thats logical. But what is the best-practice i should use in the future? I would not like to use the Name and Pluralization options mentioned in ScottGu's blog or rename the properties of my Customer class.
How dan I dynamically create some public properties on a custom webcontrol.
For example, web control has 5 TextBox controls. I need a public property for each TextBox control to be able to set a specific property of the TextBox control.
I want to be able to loop the controls in the webcontrol and create a public property for each TextBox control.
I am trying to create a Public Sub / Function that will allow me to pass certain variables into it and this will affect the output. e.g. DIV ID = InfoDiv CSS Class = "Warning" LBInfoMsg.Text = "An Error has occured" DIV Visibility = True or False
I would like to type something similar in the code behind page: InfoMsg(InfoDiv, "warning", "An Error has Occurred", True)
Public Sub InfMsg(ByRef MyDIV As System.Web.UI.HtmlControls.HtmlGenericControl, ByRef CSS As System.Web.UI.WebControls.Style, ByVal strMessage As String) strMessage = strMessage.Replace("'", "''") MyDIV.Attributes.Add("Style", "warning") MyDIV.Visible = "True" End Sub
I need to convert the following code, so that it exists as a created class "Payroll" that utilizes "Get" and "Set" elements. Unfortunately, I'm completely lost.
Public Class frmPayroll Private Sub frmPayroll_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I have to make a VB project for one of my college Co-Sci classes. However, I am having issues doing what I think is logically possible. Part of our project entails creating a user defined class, then create a form that then instantiates an instance of the object type. After that we are to list the item in a listbox. That is all well and good and works fine.
What I need help with is looping through each object in the listbox, getting some data from the object, then moving to the next.
I have been trying something similar to c++. For example, an object contained in a c++ array can be accessed like this:
array[index].someObjectMethod().
How would someone do something similar to that for objects contained in a VB listbox? I imagine it starts something like this:
I have a bunch of private variables I've typed out and I want to put all of my corresponding Public ReadOnly Properties in a bunch below them.Is there some way of copying ten lines of
Private _myVar As String
and pasting in ten sets of
Public Readonly Property MyVar As String Get Return _myVar[code]....
I'm currently copying the whole bunch of variable declarations, Find+Replacing Private _ into Public ReadOnly Property then going line-by-line expanding the definitions and writing return statements.how to avoid all this nonsense in the future, as I'm developing on a virtual terminal server, and the input lag on my little copy/paste/type operations on the code is driving me up the wall.
At runtime, I have a collection of rows (Row class). Each of them consist of column values, represented by instances of a ColumnValue class. The name of the columns are determined at runtime, and are in a separate columns descriptor collection (Column class).I want to create a DataGridView that displays all Row instances. Of course, the DataGridView's columns shall be exactly those specified by the Column instances in the containing collection.But since DataGridView's columns can fetch their values from a list item's public properties only, and I cannot easily define such a property at runtime, I cannot use DataGridView to display the tabular data.
' Classes for table structure representation Public Class TColumn ' describes my columns Public Name As String
ok basically i was trying to make a Control that exposes its protected properties to the public. example, you could call the protected DoubleBuffered property publicly. the problem is that this class called ExposedControl must be compatible with the type System.Windows.Forms.Control, meaning i should be able to create an ExposedControl using an existing Control so i had something like this in the constructor.
Public Sub New(ByVal control as Control) Me = control
Can one client call a public property within a VB.NET module and see the value of that public property changed by another client accessing it at the same time?
[Code].....
I'm running into random instances where it looks like another client might be modifying (by setting) the value of GetSetDateTime DURING the first client's run through of WhateverMethod(). This is alarming to me and I've been trying to figure out if that's a possibility.
This is another one of my "I think it's not possible but I need confirmation" questions.I have a base class for a bunch of child classes. Right now, this base class has a few common properties the children use, like Name. The base is an abstract class (MustInherit)Technically, this means that everytime a child class is instantiated, it lugs around, in memory, its own copy of Name. The thing is, Name is going to be a fixed value for all instances of a given child. I.e., Child1.Name will return "child_object1", and Child2.Name will return "child_object2".
I have a class in which some of the fields are also classes.I can put values in the "normal" properties, but in the others when o try to assign values it gives the: "Object reference not set to an instance of an object"But the code compiles fine.
dados_Defenicao = New ServiceReference1.draftClaimEntryDefinition dados_Defenicao.arCode = "123" dados_Defenicao.claimMarket.warrantyType = "w" - Here it gives the error

I'm getting an error in .net when trying to declare a Public class on my code behind page.
Partial Class _Default Inherits System.Web.UI.Page
Public someVariable as integer Public someClass as className
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load [...]
The error I'm getting is BC30508: 'someClass' cannot expose type 'className' in namespace '<Default>' through class '_Default'.The goal here is accessing the class properties in script blocks on the aspx page like this <%=someClass.classProperty%>
I'm not sure if I'm trying the right methods (I've tried several ways of declaring the public class) or if it can even be done..
I am making a program where there is a number of strings are needs and they need to be pre-defined. I rather not store it all in a XML file as I don't want anyone going in and altering them.
Has anyone ever created a class of public constants just to make cleaner code or is it considered bad practice?
I have a class that is primary configuration for my application. It has 70 plus public collections that holds all my data. I am trying to do a For Each through each of these public collections, so that I can process the data through my code, but I am getting following error:
I've got an issue where Public Events in a class aren't being seen outside the class. Code looks like this: Public Class Class1 Public Event Event1(someargs as object) Public Sub New() 'Perform Some Code RaiseEvent Event1(someargs) End Sub End Class
Can i add an event to a Public NotInheritable Class?, in particular i would need to have an event that would listen to property change.System.Web.ClientServices.ConnectivityStatus has a property IsOffline, i would need to know when this property has changed?
I have Errorlog.vb in my vb.net 2008 project. It is for public class. Public Class ErrorLogger I want to call this public class anywhere. So on EACH vb file I use import "mainproject name".ErrorLogger How can I declare once some where at the beginning and that class will be availabe through out the project?
I have this public class Public Class commonSettings Dim etcString As String = "some string" End Class How can I call etc String and use it entirely on my code?
