Initialising New Label In Code - Object Reference Not Set To An Instance Of An Object

Nov 28, 2011

I'm converting an application from VB6 to VB.NET, and am required to declare and initialise some controls in code (control arrays). I have it declared globally, so other forms can access the data stored within them, and then I try to manipulate them inside the Form_Load() sub:

Public lblDataZone() As Label
Private Sub Form_Load() Handles Me.Load
lblDataZone(0) = New Label

[code]....

The error I get says "Object reference not set to an instance of an object". I feel like I'm missing something huge here, but what's wrong with it?

Create A Button Or Label That Is On A Form That Has Also Been Created Programmatically

Sep 11, 2009

I have code that refers to controls like buttons and labels and textboxes (obviously), but i want to create them programatically, how can i create a button or label that is on a form that has also been created programatically. Here is what i have:

Dim frmIndashone As Windows.Forms.Form
Dim vscPage As Windows.Forms.ScrollBar
Dim lblPageNum As Windows.Forms.Label
Dim txtVector As Windows.Forms.TextBox
Dim txtPageCode As Windows.Forms.TextBox

I am asking because i have a With statement that assigns different values to the different things that looks like this below:

RaiseEvent Load(frmIndashone)
With frmIndashone
.vscPage.min = 1

[code]....

But i am told on everyline of the second snippet that vdcPage, lblPageNum, txtVector and txtPageCode are not members of windows.Forms.Form, How can i make them members?

Label Size - Drag The Label Object From The Toolbox And Drop In The Tab Control Container

Feb 4, 2007

I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.

VS 2008 : Create A Button Through Code?

Jun 25, 2009

I know how to create a button through code. I also know how to make a new event for that button. The problem that I am having is creating an event for a button if I do not know what the button is going to be. For example if I wanted to allow a user to have custom buttons that they can setup and link on my form how would I create an individual event for each one, or how does that work?

Create An Object From The Class - Use The Object To Interact With The SQL Db?

Apr 12, 2006

I am developing an IT Asset Tracking application using VB 2005 and SQL Server 2005 Express edition. Will I need to create classes to represent objects such as Computers, Printers, Scanners/Faxes, Contracts, Purchase Orders etc or are there any other approaches.For example, if I am correct, I will have a class called Computer and its properties will include Make,Model,CPU,Hard Disk,Memory etc. Is this the right approach.

Computers can be split up into Desktop PC's, Servers and Notebooks. Would I have to create separate classes for these as well or would they be ok under the Computer class.Once I create an object from the class, how can I use the object to interact with the SQL db.I am a beginner to VB.NET 2005 therefore I am slowly getting to grips with OOP.

Getting Code Of An Object Is Executing Even When The Current Object Is Nothing?

Jan 19, 2012

I stumbled upon the statement "If Me IsNot Nothing" several times. Often I find this in WinForms samples.I dont't get the sense or meaning of this line. "Me" refers to the current Object or Form, so if I am executing this line "Me" can't be Nothing. Or am I missing something here?Is there a way that Code of an Object is executing even when the current Object is Nothing?
