View 6 RepliesInside The Service Class, Declare A Class Variable Named Started?
May 8, 2012Create a class named Service. Inside the Service class, declare a class variable named Started. The datatype of this variable is Boolean.Public Class Service Dim started as Boolean End Class Create a class named Server. Inside the Server class, declare a dynamic array that can contain elements of the type Service.(Note: For convenience, both the array and the variable Started can be accessible from a client program that creates an instance of Server and Service respectively)
Create a constructor for the Service class. When the constructor is executed, it will set the value of the class variable Started to True. Create two new classes: WebServer and DatabaseEngine. Both of these classes inherit from the class Service. Inside the Service class, declare a Sub procedure (method) named Terminate. This method should display the following text Service stopping in a message box when executed.This method can be overridden in classes that inherit from Service class.
Inside both the WebServer and DatabaseEngine class, override the method Terminate inherited from their base class Service. Both methods should first call the base class Terminate method. The messages Web server stopping and Database engine stopping should also be displayed in a message box when the Terminate method for the WebServer and DatabaseEngine are called respectively. These messages should only be displayed if the Started variable inherited from their base class is not equal to False.
Inside the Server class, declare a method named Shutdown. This method does not return any value. When executed, it will call the Terminate method for each of the Service instances (if any) in the arrServices
array. You should call the Terminate method within a For Each loop that loops through the elements of the arrServices array.
In the Sub Main method, create an instance of the class Server. Set the size of the arrServices array in
your Server instance to contain 2 elements. Create first a WebServer instance and then a DatabaseEngine
instance into this array. Call the Shutdown method from your Server instance.
Declare A RANDOM Class Instance At CLASS Level?
May 6, 2010If you run this code you will see that the 500 PictureBoxes that are added ( this is easier to show than adding pixels as a pixel is only a single point ) fall mainly on the diagonal.With regard the RANDOM class, why should this be like this when the bounds of the instances are? >>
p.Location = New Point(x.Next(0, Me.Width + 1
), y.Next(0, Me.Height + 1 ))
as in this code.>>

View 4 RepliesGlobally Declare A Class?
Jun 1, 2009I know you can globally declare a structure so every class knows it.But I have a class named "WPNConnection", but I was wondering if you do like.Public WPN as new WPNConnection but so every class in the whole project could access it. It's just annoying having to raise events to get back to the class holding it, or finding the main class and finding it declared there.

View 6 RepliesOOP - Declare Two Datatables And Fill Them Both From A Datatable Returned By A Function In Class
Sep 27, 2010When I declare two datatables and fill them both from a datatable returned by a function in class, that when i filter the one it seems to filter the other aswell?
For example:
I declare the datatable and initiate my class:
Dim DatatableOne As New Datatable
Dim DatatableTwo As New Datatable
Dim MyClass As New MyClass
I then call the function that returns a datatable and apply it to datatable1 and 2 Then fill two DataGrids with the table:
DatatableOne = MyClass.GetTable()
DatatableTwo = MyClass.GetTable()
DatatableOne.DefaultView.RowFilter = "Name = 'Tom'"
[CODE]...
For some reason i don't understand but both grids end up with the filtered data?
Declare A WithEvents Class In Windows Form Designer Which Is Not Control Base
Jun 4, 2011I am making a TabStrip control to hold a number of tabs just like TabControl, but only with the tabs, no page. The control has a "Tabs Collection", which stores a list of "Tab" class. "Tab" is not inherited from Control, but each tab has its events. So when the user add a "Tab" in the "Tabs Collection", each "Tab" instance should have a (Name) identifier, which user can access it in the code, and with WithEvents keyword so users can add event handlers to each "Tab". The expected out come should similar to this:
Friend TabStrip1 As TabStrip
Friend WithEvents t1 As Tab
...
Me.TabStrip1.Tabs.Add(t1)

VS 2005 Declare Size Of Array In Structure
Dec 11, 2009I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.
In VB.net: Code:
So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?

View 2 RepliesMake A Control Reusable In Different Projects?
Jun 22, 2011Is there a way to not put the project name in the Inherits attribute?
I am working with vb and I have multiple projects, that have multiple web pages. In each of these projects I create controls that are reused in the web pages.
Each control I have is declared like this:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="MenuBarControl.ascx.vb" Inherits="**projectName**.MenuBarControl" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
When I want to copy the control into another project I have to change the **projectName**. Having to change the project name for each project makes the code not reusable. Changes made to specific projects each time is not reusable.
I want to be able to omit the project name in the Inherits attribute. When I do that now I get an error
Parser Error
Parser Error Message: Could not load type 'MenuBarControl'.
Reusable Custom Control With Properties?
Nov 13, 2009I have built a Custom Control Class that makes it much easier to build a side bar element in my html.
