I have absolutely no idea what you mean by "suggest me with the suitable array list" - you shouldn't be using ArrayList anyway, there were superseded by the Generic List<T> class many years ago...

But...if you create a dynamic check box (and generally speaking, it's a poor idea, there are normally better ways to handle this kind of thing) all you need to do is keep a reference to it at a class level when you construct it: move the checkBox variable declaration to the class instead of inside the method and it will be persisted for later use.

Alternatives, you could look in the Controls array and find it - but unless you add a distinguishing feature such as a Name property, you won't be able to tell which is which if you create more than one.

No - because I have no idea what you are trying to achieve!
I assume this is part of your homework - but I don't know what homework you have been assigned...

Hi ...
When you create your Checkbox you should give it a Name. With this given Name you could find in inside the controls-collection of the from (or the container-control) to ask for it's checked-state.

Another possibility is to add a handler to a named Sub which allows you to react directly on the changing of the state of the Checkbox. But ... when you use this way you must later remove the handler when you dispose the form, you are in.

You can user OfType method in VB.NET.

If you have multiple controls of same type or one control, Use following method :

VB

for each CheckBox as CheckBox In <controlcontainer>.Controls.OfType(Of CheckBox)()
     <controlcontainer>.Controls(CheckBox.Name).Text)
next 
</controlcontainer></controlcontainer>
