Private Vs Protected - Button Click Event Is Created In ASP.NET ?
Feb 22, 2012
In ASP.NET using VB.NET, you can define the wired up button click event (to an ASP.NET server control) in 2 different ways (for the purpose of this conversation - manually wiring up via button property not in question here):
Double click on the button in the designer which produces an event in the code behind with a Protected method.In the code behind, select the button from the list of controls, and then select it's 'Click' event. This produces a Private method.I understand the difference between Private and Protected; why based on how the wired up event is autocreated it generates a different Access Level on the method?

I'm writting a program that will output the column headings of the database onto a form in a label along with a text box for the user to input their own information and a button to add a new record in the database. My problem is I do not know how to refer to the text boxes or how to call the click event from the button that was created at runtime.

I have two forms. Form 1 you click a button, and it opens Form 2. Form 1 is still open.
When you click a button on Form 2, I want to run a Private Sub that is on Form 1, whilst Form 1 is still open.
The idea is that the data i've entered on Form 2, once I close this form, I can continue working with Form 1 with the updated data without having to close and re-open it.

I have created a program that allows the user to click on screen and add many ovalshape objects. But I have got stuck as now I need to create a rightclick event for any of the runtime generated ovalshapes on screen and dont know how to refer the right click event to all the many objects?
My code for creating the oval's are as follows:-
Dim
Drg As New ShapeContainer
Dim Shape As New OvalShape
Drg.Parent =
Me
Shape.Parent = Drg
Shape.Size =
New System.Drawing.Size(10, 10)
Shape.FillColor = StampColor
Shape.FillStyle = FillStyle.Solid
But how do I write a click event now for any of these runtime created objects???

I'd like to have a Private or Protected "Setter" for a property that also happens to be an abstract (MustOverride). I'm porting some code from C# to VB and in C# this is pretty straight forward. In VB not so much (for me anyway).
Some code...
In C#...
public abstract class BaseClassWithAnAbstractProperty
{
public abstract int AnAbstractIntegerProperty { get; protected set; }
}
[Code]....
The issue seems to be the inability to flesh-out the Get/Set specifics in the declaration.

How can you add a click event to dynamically created menu item?I thought I could do something like
Loop through all the items in the Menu1.DropDownItems then create a mousedown even on the item and execute an action based off that.I'm new to VB and was wondering what logic to use. Will that even work? How will the events be saved through the life of the application?

What purpose do protected or private (non-static) events in .NET really serve?It seems like any private or protected event is more easily handled via a virtual method. I can (somewhat) see the need for this in static events, but not for normal events. Have you had a use case before that clearly demonstrates a need or advantage for a non-static protected or private event?

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

For i = 0 To 9
Dim Browser As New WebBrowser
Browser.Name = "Browser" & [i]
Browser.Navigate("[URL]")
Browser.Visible = True
Next
So now I will have 10 webbrowsers aimed for google, right? So how do I make a loop that clicks the search button 10 times? I know I need to use member_invoke like this
Browser.Document.GetElementById("search").InvokeMember("click")
But I have no clue how to code the loop.

Can i Know how to catch between these 2 event, Leave and Click?
I have one checking in a textbox Leave event. I will go check whether this ID is already exist in DB or not. If exist, I will prompt MSG box to user.

So, the form remains open without trigger Button Click event.
how to prevent this textbox leave event or how can i catch/control this situation?

I created a button in DatarGrid. Now I want to click that button and only when I click the button should the event be fired. Actually I want to Delete that particular row once the button is clicked. However, when I click the button, the Event: CellContentClick of the DataGrid gets fired. And that means if you click anywhere on the Datagrid, that even will be fired, and that makes no sense to put a Delete button. So I want to keep the Delete button and once the Delete button event gets fired, the record gets deleted.

Is it possible to call a protected method via reflection. I am using this:
Me.GetType.InvokeMember(Stages(CurrentStage),
Reflection.BindingFlags.InvokeMethod,
Nothing,
Me,
Nothing)
Which always calls a method with no params or return. The idea is that the user of my object (transactional processing of business logic) inherits the base class adds in a load of private methods to fire. They then add these method names to a list in the order they would like them fired and the code above will take care of firing them.
It works fine with public methods but not with private or protected methods in the same class (Protected because I have some 'standard' pre built methods to add to the base class). Realistically I could make the methods public and be done with it but my inner nerd wont allow me to do so...
I am assuming this is a security feature. Is there a way to get around this or does anyone have any suggestions on how to proceed but keep my tasty, tasty visibility modifiers in tact?
(NOTE: ITS IN VB.NET but a C# Answer is fine if that is what you are comfortable with).

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.
I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.
How can this be accomplished?
