View 3 RepliesDll - Public Properties From Another Class
Mar 8, 2012I'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.

How To Handle Public Properties
Dec 31, 2009Within 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.

Creating Public Function / Sub To Set CSS And Other Properties
Jan 11, 2011I 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

View 1 RepliesAccessing Public Properties Of An Object Contained In A Listbox?
May 8, 2011I 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:
myListBox.Items(index).
Copying A Set Of Private Variables Into Corresponding Public ReadOnly Properties?
Oct 18, 2011I 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.
Does DataGridView Always Depend On Public Properties For Column Values
May 26, 2011At 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

Make A Control That Exposes Its Protected Properties To The Public?
Jan 30, 2010ok 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

Public Properties Within VB Module - Cross-client Behavior
Oct 15, 2010Can 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?

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.
.net - Using A Class Like A Public Variable In Asp.net?
Apr 13, 2009I'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..

Public Variable Goe Out Of Scope In Private Sub?
Aug 23, 2009I have a public variable which seems to be going out of scope. I am confused as it has been dimensioned as a public variable: Public xlCell as As Microsoft.Office.Interop.Excel.Range
I originally had all my code in the same module in the same project and it was wrapped within a For/Next Loop (Example 1). I decided to clean up my code and make it more modular (Example 2). All the code is still in the same module in the same project.
Upon doing so, my public variable is not recognized in any of the private subs that I have created. I keep getting the following error: Message="Object reference not set to an instance of an object." When I test the variable using ?IsNothing(xlCell) in the Main Sub I get False in the main sub. this tells me te variable is recognized. However as soon as the Call SelectCaseSub() is triggered, I get a True value for ?IsNothing(xlCell). Why is this? Shouldn't this variable be in scope regardless?
