when we have a method of a derived class implementing a method of an interface which is already implemented in the base class, the compiler throws a warning (by default). when i see a warning i will try to erase it and the only way to erase this warning is to mess with the settings of the compiler hence i hope that there is a way to declare "how" a method implements an interface's method. by this i meant that we should be able to declare overridable, overrides and shadows for the implements keyword. hence if we declare overridable-implement for a method of a base class implementing an interface's method, the compiler should give no warnings when we override this implementation (re-implementing in a derived class). Similarly, if the method of the base class implementing an itnerface's method was not declared as ovveridable-implement, the derived class should be able to Shadow the implementation example code which flags unnecessary warning:
What are the behaviors difference for the Previous Property of Other1 and Other2 Class.Note than the return type of the ovrloaded Previous Property of Other2 as bean changed to Other2 while it stay as Base for Other1.
Public Class Base Private _Previous as Base Protected Overridable ReadOnly Property Previous As Base
Currently im trying to write a HotKey class, however in order to intercept the messages you need to overwrite the WndProc and check for WM_HOTKEY.
Currently, im using Inherits Form inside of the class, so that it has the option of overwriding the wndproc, but along with that I get all the forms normal events when trying to handle it.
Below is my
Public Class Form1 Private Class HotKey Inherits Form
I knew VB.net is very weird when talking about shadows and overloads, but this this I'm completely baffled.I'm working with a model similar to the following one. Parent class:
Public Class Base Function F() As String Return "F() in Base Class" End Function
I'm using the standard code for form drop shadows that creates an effect identical to that of XP's, but you will notice in Windows 7 that the shadows are much larger, are not visible only on the right & bottom sides of the form (example: [URL])
Here's the code I'm currently using:
Private Const CS_DROPSHADOW As Integer = &H20000
Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
[CODE]...
Is there a way to expand the shadow to resemble Windows 7 more?

I'm unable to find out how to do this, so either it's not possible or I'm using the wrong keywords.
Basically, I want to add something to my base class method (Overridable), so that when a derived class Overrides it, some comments appear along with the "MyBase.MethodName".
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) MyBase.OnPaint(e)
'Add your custom paint code here End Sub I want to have my own equivalent of "Add your custom paint code here".
I have this class Public Class DGVMod Inherits DataGridView
Protected Overrides Sub OnEditingControlShowing(ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) MyBase.OnEditingControlShowing(e) Try
Warning1property 'Events' shadows an overloadable member declared in the base class 'MarshalByValueComponent'. If you want to overload the base method, this method must be declared 'Overloads'.
I am trying a example codes of animated graphics. I rewrote all the code and I found an error which doesn't happen on the example code(I run the example project)
error: 'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.
when I double clicked the error, I got this in Form1.Designer.vb:
'Form overrides dispose to clean up the component list. <System.Diagnostics.DebuggerNonUserCode()> _ Protected Overrides Sub Dispose(ByVal disposing As Boolean)
I am cleaning up some code and I have multiple classes that are 99% exactly the same. So my understanding is that my options are...
1. Create a class and all other classes inherit from it and modify it a bit
2. Create an abstract class and all classes inherit from it and modify a bit ** I took this route
3. Create an interface and all classes Implement that interface.
Here is my 'original' class below (the one that all of them look 99% identical). This class is used in an arraylist so I have a listing of all my images from a folder I have searched.
I've wanted to know the answer to this question for a long time but I never really took the time to ask anyone. My question is, why do rounded edges or drop shadows of transparent form layouts turn white. Take a look at the following image to know what I'm talking about.
I placed this checkbox named owner on my form. When i build the project i got the error as Quote: 'owner' conflicts with property 'owner' in the base class 'Form' and should be declared 'Shadows'
I am converting an application from vb.net 2003 to 2005. I got the following warning and need help how to resolve it. withEvents variable 'PreviousPage' conflicts with property 'PreviousPage' in the base class 'Page' and should be declared 'Shadows'
Yesterday I started my first DLL project which is for ArabicMessageBox that will allow arabic programmers to display there message in totally Arabic message.My project contain one Form only, and the basic code that I use is:
Public Overridable Function Show(ByVal APrompt As String) As MsgBoxResult mLoad(APrompt, MsgBoxStyle.OkOnly, "") Me.ShowDialog()
What does this error mean? I havent modified anything in the designer code, but its giving me an error? WithEvents variable 'Move' conflicts with event 'Move' in the base class 'Control' and should be declared 'Shadows'. The error relates to Friend WithEvents Move As System.Windows.Forms.DataGridViewCheckBoxColumn
I have a base class (ex: Class1) containing a list of another base class (ex: ClassA). Each child class of first base class (ex: Class1AA, Class1AB,..) containing a list of child class of second base class (ex: ClassAA, ClassAB,...)The client must never know which child class is using, then i don't think i can use generic for my bases classes.I try something like this and many more, but i always received errors..Imports System.Collections.Generic
I am inheriting some .net code and they use a couple things i am unfamiliar with and was wondering if someone could shed a little light on why they are used.
Here they are:
Public Shadows Sub RemoveAt(ByVal indextmp As Integer)
When and why would you use "Shadows"?
Public Overloads ReadOnly Property Count() As Integer
