I don't want to specify OwnerForm inside the user control. I know a solution to add manually handlers for MyUserControl.tb.TextChanged to some functions on a owner form, but I think it's bad way.

Inherit And Then Override A Resource Or Contents Of It In .NET?
May 21, 2012I have a project, let's call it "BASE", that has a bunch of .CSV files as Resources. The project makes references to My.Resources.XXXXXXX in different methods where XXXXXXX is the CSV filename. I am working on a class that derives from "BASE" and I would like to change some of the .CSV files and replace the ones that are in the "BASE" project with mine. I would like the methods in the base project to use my CSV files when it calls My. Resources. XXXXXX instead of the files that are in "BASE"'s Resources. Any tips on how to do it? (any .NET language is welcome)
View 1 Replies.net - Override A Class/add Properties To A ListviewItem?
Jan 12, 2010I have a listview but I would like to add 3 properties (for example one of them is "image") to the listviewitems in it. I was fine with making a custom class with the 3 properties and just inheriting ListViewItem but now I need to use MultiSelect, so it means doing things like(in For Each loops):
ListView1.SelectedItems.Item(i).Image don't work because it returns a ListViewItem not my CustomClass. I could always do : Ctype(ListView1.selectedItems(i), MyCustomClass).Image
But using that over and over again seems like a waste/wrong way to do it?
.net - Override Variables Declared In A Class?
Dec 16, 2010I'm trying to create a generic Controller Class for generic events. But these these events still need to access their class variable. So my idea is to create the Base Controller Class with a ModelBaseclass variable as _ClassVar, which is inherited by all of the other class Controller classes will derive from. But I want the derived controller classes to override the _ClassVar with whichever one they need.
I want to do this, so the ControllerBaseClass can have all the generic functions that all the Derived Classes would use.
Model :
Public Class ModelBaseClass
Public Overridable Function Foo() As String
Return "Name"

C# - Override/Handle Own Type Conversions In .Net
Apr 20, 2011Is there a way to define an implicit conversion operator in VB.NET?
I can't remember ever seeing or hearing of anyone do this; but now I'm in a situation where I think it would be incredibly useful to define my own custom 'type conversion' for my class.
As an example - let's say I have my own class, 'AwesomeDataManager'. It does not inherit from DataTable, but it holds data in a similar fashion to a DataTable. I would to be able to say, 'myDataTable = CType(MyAwesomeDataManager, DataTable)' and have it execute some code inside my class that would return a populated DataTable.
Granted, I could do something like 'MyAwesomeDataManager.GetDataTable' but for the sake of integrating with an existing code base, I'd like to avoid it.
C# - XMLElement - Override Output Format?
Feb 12, 2012what method would i need to override with a custom XmlElement to format the body in a certain order?Currently, when the class is instantiated, i have it auto-fill the Default Value from the DefaultValueAttribute and create the initial child elements through the constructor.What i want to do is make sure that the Elements child nodes are in a certain order. This is not a webservices Xml Transformation but a simple file output for a User Interface.
I tried overriding InnerXml but that was a bust. If i dont create the initial child elements from the constructor then they never show up.
[Code]...
Actual output would not be in a XSLT format but this should get the format i am looking for. Currently, what ever is edited last is at the bottom, and i want to have the various object properties to be outputed in a certain order in the ChildNodes of the parent. I want to have the iteration overload to a minimum. I would rather handle the childnode creation be handled on the output of the class into XML format.

View 3 RepliesHow To Override Dataset.Desinger Property
Nov 20, 2009In my project, I have a table that has an image column, but with vs2008 it stores the image as bytes. I have the column set to allow nulls. When I save my image I convert it to a byte array. Then when I retrieve that row, I convert the byte array back to the image, no problems. The problem is when there is not an image selected I return Nothing to the datatable, saves ok, but when I try to retrieve that row, The dataset.desinger throw the "value in column dbnull". I can temporary override this error with a code change in the dataset.designer, but it does not stay permanently. How can I override the dataset.desinger property permanently.
Original dataset.desinger code:
<Global.System.Diagnostics.DebuggerNonUserCodeAttribute()> _
Public Property Image() As Byte()
Get
Try
Return CType(Me(Me.tableCustomers.ImageColumn),Byte())
[Code] .....
All I did is add the if statement capturing the dbnull and forcing it to return Nothing instead. When I close VisualStudio, then reopen this change is gone. How can I keep this or override it.

Jun 2, 2009Ok, I've been searching all over the web for an answer to this and I'm getting nowhere. I've found several examples and tried code translators, but they either fail to compile at all (syntax is wrong) or fail to solve the problem. Here is what I am up against:
I am trying to implement a service object class for the POS for .NET library using VB9. Specifically, the BillDispenser class. I define my class and inherit from Microsoft.PointOfService.BillDispenser. As normal, it creates stubs for all the MustOverride (abstract) properties and methods that I need to override (I love that), EXCEPT for the DirectIOEvent. Apparently this event is defined as abstract in the POSCommon base class, but VB doesn't generate a stub for it.
No compile errors are generated from not defining it, but I get the following runtime error as soon as my unit test attempts to load the dll[code]...
