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

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 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).

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.

I have to create a project management application in VB.Net Framework 4 which should create a client folder in a public folder in Exchange server.
I think the only way to create a public folder is through the management console. Is there a way to connect to the Exchange server and execute the creation command file from the code but I do not know how.

Class A gets, as part of it's constructor, a pointer to class B and saves that pointer in a private variable. Class B exposes a public function, F. I'd like for class A and all classes that inherit from class A to NOT be able to call B.F.The idea is that class A will implement its own version of F, one that calls B.F, but the rest of the code should not be calling B.F. If it matters, the two have different function signatures.Maybe another way, like a class C that inherits from class B and hides the public functions? (Cant that even be done?)

I have a public function declared in my code-beside on default.aspx.vb. I needed to add a second page to my project and copied and pasted that function into the second page, but when I test the page I get an error saying there's a conflict with the same public function on the default page.
If I remove the function from the second page, i don't get the error, but will it still be accessible if called on that page, even though it's on the default page? Or do I need to place it somewhere else so that it's accessible to both pages?

I have a Function for checking the input in a textbox and only allowing Numeric & Backspace; everything works fine so far. My form is for financials and it has about 20 textboxes; they all receive Numeric only data; there is NO alpha data on the entire form required. Note in the snippet below that I don't even need a decimal point as well.
Is there a way to handle ALL textboxes on this form without having to place the Function call in each textbox KeyPress event. took a long (5 year) hiatus from developing VB6

If (KCode >= 48 And KCode <= 57) Or KCode = 8 Then

I have a situation where I have several VB.NET Modules in the same Logical-Module of a large application. I would like the update function of each module to be public, but I would like users to be forced to qualify the function call with the module name.
ModuleName.Update()
instead of
