When you type sender. IntelliSense lists 5 methods and yet if you type sender.Left or sender.top these will work. Why don't these properties show up as available for use via IntelliSense.

I came across a DbParameterCollection object, which should have an "Item" property inherited from IList, but IntelliSense does not show this object has the Item property.
View 2 RepliesI am writing my first class-library in VB.NET. My idea is to distribute this library so others may use it in their applications.However, perhaps due to my lack of experience in writing and structuring the library and the classes therein, I noted that the methods/properties are ALL being shown in the IntelliSense of Visual Studio.
The thing is that many of them are only used within the library itself and should NOT be used by the developers (could create a disaster) when they incorporate my library in their application - only a few should be visibile i.e. the ones which are needed by the developer.Thus, my question is: is there a way to hide certain methods/properties of my library from Visual Studio's IntelliSense? Maybe something similar to REM?
EDIT: as mentioned - this is my first library and I now understand that my question could be intepreted in two ways:
1) how to hide something from IntelliSense
2) how to prevent a developer from using and calling certain methods/properties
Of course, the end-result that I want is that the developer is not able to access AT ALL certain methods/properties i.e. No. 2 above.
When working with the code within a control's subprocedure if you type it brings up intellisense as you would expect: Code: sender. Within the intellisense there is no text property listed to select from however if you just type "text" after the "sender." it allows it. It also doesn't capatilize the T in text after you leave the line as you would expect to see when working with other properties. This is the first occurence that I've seen where an item was not included in intellisense but allowed it without errors. This is a big code saver and discovery for me as it cuts my other previous methods of extracting the control's text down to a single simple line.
View 2 Replies(me = an absolute beginner in WPF / VB2010) how to get the type of sender in (ByVal sender As Object)? Purpose: when two different Objects call the same subroutine, find out which one actually called it.

I am trying to get my code working as per the instruction on [URL]So far I have the wrapper:
Public Delegate Function PredicateWrapperDelegate(Of T, A)(ByVal item As T, ByVal argument As A) As Boolean
Public Class PredicateWrapper(Of T, A)
Private _argument As A
Private _wrapperDelegate As PredicateWrapperDelegate(Of T, A)
[code]....
Then I try to call it from my code:
Dim children As List(Of String) = toplevel.FindAll(New PredicateWrapper(Of Integer, Integer)(Did, AddressOf DidMatch))
I then get an error on DidMatch ... Error Method 'Public Function DidMatch(item As DeptMenuData, did As Integer) As Boolean' does not have a signature compatible with delegate 'Delegate Function PredicateWrapperDelegate(Of Integer, Integer)(item As Integer, argument As Integer) As Boolean'.
I've been using the System.Net namespace ever since we switched from .net Framework 1.1 to the 3.5 framework, but there's one thing that's been puzzling me since. What's the difference between the Sender and the From properties in the MailMessage class?Are they both the same, and if not is there a reason to use Sender together with From?
For example:
Using m As New System.Net.Mail.MailMessage()
m.Sender = New System.Net.Mail.MailAddress("test@test.com", "Name here")

I've wondered this for a while, when I hover over an object's properties when the program is paused (from a breakpoint) I can see the values of each property but when it comes to a collection it wont list the objects in the collection unless I specify an index, how do I specify an index?Basically I have a form with a ToolStrip that has 12 items in it, I would like to see what the 12th item is but can't because it's an indexed property.

I have a combo box and a property grid in a form. The combo box contains 2 items. If one item is selected, two properties are listed in the property grid. These properties should have a dropdown that contains a list of items. I have two string arrays that contain the values for these properties. Can I use one TypeConverter that inherits StringConverter for these lists to be displayed in two different properties? That is, with one TypeConverter class, can I populate both the lists? I will also have to do the same with the other items in the combobox.
View 1 RepliesWhen I write public events for my business objects, I've adapted the habit of always passing the instance as "sender as Object", in addition to additional specific parameters. I just asked myself now why am I not specifying the class?
So for you with more experience; Do you ever pass the distinct class as sender in an event? And if so, what are your decision criteria for when this is ok/not ok?

I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?

I have a class definition that I've seen other define properties that return collections of objects.
Public Property GetAllAdults() as Adults End Property I made the argument that this should be a method in the class, because it doesn't define an attribute of the class, and could not be extended with parameters. Is/Are there reasons why this should be defined as a property vs. a function?

1. The cmd window normally shows various status messages in colour, whereas the RichTextBox shows all messages in Black (on a white background). How can I get the RichTextBox to show the messages in the same colours that the cmd window displays?
2. As the RichTextBox fills with data, filling the box, and beyond, and the scrollbar starts to shrink, I notice that the data at the top of the RichTextBox stays there, and you would have to scroll down to see the last status message, whereas I would like it to do the reverse, i.e the last status message is at the bottom of the visible RichTextBox, and if I wanted to see the earlier messages I would have to scroll up. How can this be achieved?
