How can I cancel a thread which is displaying a msgbox ?

What exception are you getting?

Presumably, you are getting a ThreadAbortException ;)

Personally, I would NEVER use Abort on a thread. You should just find a
code path to exit the thread. For starters, .NET does not deal with thread
abort while using COM objects very well - and secondly, it's just better to
set a variable in your thread loop to exit.

I have a thread which is displaying a msgbox. I need to programmatically
cancel the message box if the user does click on OK. I tried to abort
the thread T1.abort() , but am getting an exception. Is there a way to do
this?

I am calling msgbox, this means that my thread is not
in my control, so what message loop are you talking about?

? You are creating the message box within the thread? So the thread is
blocked until the user responds to the message box. I'm not sure I
understand why you need to "cancel" the message box. Surely, the message
box dissapears when the user clicks Okay?

It would, yes, but I need to cancel the msgbox from the other thread
if a certain something happens (and the user has not pressed "Ok" )
Is that clear now?

It might be easier and cleaner to create a custom message box (just a new
form with some buttons and a Label or TextBox).

Once you have a new MsgBox, you can simply expose a public function in your
new message box to get rid of it.
If your event model is more structured, you may need to allow your MsgBox to
subsribe to events triggered by other modules:

Someone (May not be the MsgBox) defines the event:
Public Event EventYourSubscribingTo()

New MsgBox Handles the event:
AddHandler EventYourSubscribingTo, AddressOf RoutineToDoTheWork

You can trigger your cancellation with an appropriate "RaiseEvent".
RaiseEvent EventYourSubscribingTo
