I'm making a program that allows me to drag and drop an image to a picture box. But I get this error when using the dragenter event. Here is the code:
e.AllowedEffect = DragDropEffects.All
This is code-related as in what the compiler will allow you to do in one language, but not allow you to do in another language (e.g. optional parameters in VB don't exist in C#).

I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.

I am writing a math game for my brother in Visual Basic to help him with double digit numbers(both adding and subtracting).Normally you solve a problem by writing right to left on a piece of paper. Is there any way of setting the text box to do this?
For Example:
58
+ 18
You would type in the text box '6' followed by '7' so it would read '76'I set the right to left property but it does not do what I want it to do.
I am working on an assignment, so need to pass the file to the instructor. I thought I remembered a way to input a placeholder character(s) that tells the computer that the path is flexible until the point where I declare the actual path.
For example: if the directory is C:documentsMyProjectinDebug on my machine, and is F:usersownerclass assignmentscis101StudentAMyProjectinDebug on the instructor's machine, can I put a "wildcard" type of character that points to the ...MyProjectinDebug file that will work on both machines in the Initial Directory property?

I am having a Friend Class InterceptingChannelBase class.It has a property as below:
Protected ReadOnly Property InnerChannel() As TChannel
Get
Return Me.innerChannelT
[code]....
This class is being inherited by (Friend Class InterceptingInputChannel) class which in turn contains another (Private Class TryReceiveAsyncResult) class.The property above is being used in this private class as below:
Public Sub New(ByVal channel As InterceptingInputChannel(Of TInputChannel), ByVal timeout As TimeSpan, ByVal callback As AsyncCallback, ByVal state As Object)
MyBase.New(channel, callback, state)
[code]....
I am getting the error on the above underlined statement saying that Protected Readonly Property InnerChannel is not accessible in this context because it is declared asa Protected.As far as i think,if i declare a property in class as 'Protected' then if this class is inherited by 'another' class then i can use this property and it should not throw an error.
i get the following error in the follwoing code , the word right is underlined in blue and the error is "1'Public ReadOnly Property Right() As Integer' has no parameters and its return type cannot be indexed."

Is there a way for implementers of an interface where a ReadOnly property is defined to make it a complete Read/Write Property ?
Imagine I define an interface to provide a ReadOnly Property (i.e., just a getter for a given value) :
Interface SomeInterface
'the interface only say that implementers must provide a value for reading
ReadOnly Property PublicProperty As String
End Interface
This means implementers must commit to providing a value. But I would like a given implementer to also allow setting that value. In my head, this would mean providing the Property's setter as part of the implementation, doing something like this :
Public Property PublicProperty As String Implements SomeInterface.PublicProperty
Get
Return _myProperty
