Hi All,

I am trying to call a click routine such as

VB

btnVoltsCurrent_Click(sender, New System.EventArgs())

I have done this using another click routine which has some values passed to it, I am now trying to call from a Sub() that does not have the value passed to it.
Leaving with sender is not declared errors....
HELP!

Your first mistake is that you have your code in the Click event handler. That's wrong. The code you have in there should be in its own method. That way, you can call the code from anywhere, including the Click event handler(!), and you don't have to worry about how you're going to call the code in there by passing garbage parameters to it.

I wish the obvious wouldn't be so damned hard to find to sometimes! :)

You and me both brother!

Of course, a 5.
Still the question is better than many more typical questions on "how to call event".

I know it is. Plenty of context to work with. That's the nice part about it, though someone still voted it a one and that person has just as much pull around here as I do.

As David so rightfully pointed out that the correct way to do this is to pull out the code from the button click handler that you need to call from the other non-event driven method and put that into a separate method.

However, if you are pressed for time and need to do a quick and dirty test to see if it works, you could (and I am not saying that this is right) call your button click handler with dummy parameters.

VB

btnVoltsCurrent_Click(Nothing, Nothing)

But you can only do this if you do not need the sender or the event arg parameters.

If you did not call it "quick and dirty" I would not like it... :-) My 5.

Thank you Sergey. I was actually thinking of you when I wrote it. :-)

Do you mean that you expected me to criticize the answer? I really would, but you did it yourself.

Oh yes. I knew that you would unless I qualified it enormously. :-) Cheers!
