What is the appropriate declaration such as "ValueChanged" or "Click" for a NumericUpDown that will execute the code when I press enter. I already know that setting the "AcceptButton" property of the main form to a default button will not work, especially if I want a different button to be selected depending on which control I give focus.
PS: Is the syntax any different from Visual Basic 2010 Express than it is on Visual Studio 2012 RC (running in Visual Basic Mode)?

View 9 RepliesQuestion: How to shorten this array creation ? I need to create an array of type ReportingService2005_WebService.Property with one property.
Something like:
Dim PropertyArray() as new ReportingService2005_WebService.Property(1)
I have to do this:
Dim PropertyArray As ReportingService2005_WebService.Property() = New ReportingService2005_WebService.Property(0) {}
PropertyArray(0) = New ReportingService2005_WebService.Property
[Code].....
For some reason when i declare an array and set it to a certain amount of elements then under it specify the elements it works in VB 2005 but when i do it in VB 2008 it get : "declaration expected " and i get words underlined.
Public Class Form1
Dim words(20) As String
words(1)="Computer"
End Class
Let me know how to do this in 2008!

View 4 RepliesDoes anyone know of a working declaration for the API "AccessibleObjectFromEvent"? Or a good .net equivalent? I've spent so much time getting the other main Accessible API to work on .NET, that I'm hoping to start with a good declare on this one.
I've built a really good narrator, for totally blind people so that they can interface and use the computer in a substantial way. The innovation is a static mouse that controls category input, rather than free mouse movement, and the middle wheel selects items of that category. But I need the last access API for events and voice feedback when the event occurs. I'm guessing it's something like this, according to what works for the other API: Code:
This is loosely based upon microsoft Access example written in vb6, available as an online download. I've have not seen a .NET example online, so it might prove useful for someone.

I am creating a kind of a "naive" search engine.What I have done is distributed words in files where each file corresponds to the starting letter of the words (i.e. if its English, then 26 files are there)Then when the search system loads I am loading all the words in hash tables (26 hash tables corresponding to 26 alpha-characters) for which I am using an array of structures.The problem is after declaring the variables in a Form load subroutine, the variables are not able to use those values in other subroutines..How do I properly declare them so their values persist?

Declaring Varibales where to put the declaration.
View 3 RepliesOne would think I'd already know this, but I never really gave it much thought before now. When declaring a member variable for a class, is it better to set the default value at the declaration
Private m_strMyVariable As String = ""
Or is it better to do it in the constructor
Private m_strMyVariable As String
[Code]....
Should I maybe always specify a value at declaration, even if it's Nothing, and just override that value in the constructor(s) as needed? Or is it situation specific? If so, a really quick rundown of which situations might warrant which treatment would be nice.
The Param1 works but param2 failed when passing it to method with object array parameter
Dim param1() As Object = {5, 5}
'And
TextBox2.Text = "5,5"
Dim param2() As Object = TextBox2.Text.Split(","c)
RichTextBox2.Text = CType(InvokeDllMethod(bt, "kayTestDynamicAssembly.KayTestDLL", "Addup",
param1), String)
My main question is that does .NET treat those 2 declarations differently or maybe I am missing something?
I'm trying to declare a generic using a variable of type System.Type, with VB 2005, and haven't found the right approach. Consider the typical:
Dim m_GenObj As MyGenericObject(of T)
Instead of using "T" I want to use a variable of System.Type, for something like:
Dim m_MyType as Type
Dim m_GenObj as MyGenericObject(of m_MyType)
But of course that doesn't work.

Line B - I instantiate the object
Line C - I edit data in the GameTable
Line D - I display the data in Visual Basic
Line C will crash in runtime if I don't do sometype of "New" declaration
Line B is my attempt at a "New" Declaration by I get an error message I don't understand - "Type Expected" - I think I have the syntax wrong here.

I'm working on my final assignment for my Visual Basic class, and the last assignment is to create a program which stores CD collection information. It works fine, but the task is to create a structure for the input information and use it in the Add buttons click event code.I'm not asking to have my homework done for me, but i'd like some advice on where I should declare the structure and how. Everywhere I try and declare it, it ends up closing that particular sub procedure or section. I've tried looking up plenty of help sites to learn about structures, but sadly they and the book are both very vague. The instructor also mentioned padding each entry, but that I'm pretty sure I know how to do

I'm working on a home project using DirectShow.Net. to learn some VB.net. Most of the examples I've found have all been in C# so I'm looking through code for ideas and converting where I need to. I keep stumbling upon these declarations and I'm unsure how to convert it to a VB.Net statement.[code]Then the second part seems to be assigning the value but as its made up of two parts im unsure how that works?
View 2 RepliesI have two classes; one is a data class which contains routines to handle data and the second is a utility class which contains useful routines which can be used again and again. I have come across a problem. Some of my routines in the utility class use routines in my data class and now I want to use some of my utility routines in my data class. I tried this in a service and the service just would not start. After commenting out code I realised it was because I was making a declaration in the utility class for the data class and in the data class making a declaration of the utility class.
I understand that this is now causing looping but is there a different way to do what I want. If not I would need to have two copies of routines in both classes.
i'm used to be a VB6 user and started move on to VB.NET few days ago and i'm still quite new to its new syntax.Today i came across there is a object declaration with the 'Nothing' keyword follows at the end and what it actually means? Dim l_Active As AvsIdentityType = Nothing
As i know Nothing keyword is usually used to release the instance to the object after we used it but why it is used in the declaration statement?BTW, the 'AvsIdentityType' is a public structure.
i am still new in VB.net if someon can just help with these codes below: [code] what does the () after each one of these declaration means are they arrays?!
View 2 RepliesI have some VB6 code that I am converting to VB.net and came across this section
Declare Function TmSendByLen Lib "tmctl.dll" Alias "TmSendByLength"(ByVal id As Integer, ByRef msg As Any, ByVal blen As Integer) As Integer
'snip'
[code]....
I have not come across the Alias term before but I can guess what it does. What I am unsure of is the reasoning behind overloading the alias. If that is what is happening.I need to create overloads for the TmSendByLen function as the 'As Any' is not supported in VB.net so I am not sure if I should just remove the alias or if I should leave it in place.
Very easy today, I think. In C#, its:
Dictionary<String, String> dict = new Dictionary<string, string>() { { "", "" } };
But in vb, the following doesn't work.
Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) (("",""))
I'm pretty sure there's a way to add them at declaration, but I'm not sure how. And yes, I want to add them at declaration, not any other time. :)
I've also tried:
Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) ({"",""})
And...
Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) {("","")}
And...
Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) {{"",""}}
