in vb.net how do I raise a click event for a label

Solution 1
Let's say your label is named Label1.
This Sub is the Sub that will be executed when you click on the label.
Private Sub Label1_Click(sender As Object, e As EventArgs) Handles Label1.Click
End Sub
To raise a label click, you just need to call that event.
Label1_Click(Label1, Nothing)
That's it :)
Solution 2
It's considered bad form to call the event handler method directly. Put the code you need to call when the label is clicked into a method and call that method from both the label click handler and the whatever method:
Private Sub click_assessment_menu_button(ByVal sender As System.Object, ByVal e As System.EventArgs)
runLabelCode(sender)
'other code here
End Sub
Private Sub runLabelCode(sender As Label)
current_label_clicked = sender
'other code here
End Sub
'elsewhere in the code
Private Sub Whatever()
runLabelCode(Label1, Nothing)
End Sub

I have a several labels all coded as such:
Public assessment_menu_button As New Label Public current_label_clicked As New Label AddHandler assessment_menu_button.Click, AddressOf click_assessment_menu_button Private Sub click_assessment_menu_button(ByVal sender As System.Object, ByVal e As System.EventArgs) current_label_clicked = sender ' do some other stuff End Sub
Then, later in my program, I have a Sub which needs to perform a click on whichever label was put into current_label_clicked and raise a click event on it. Something like
Private Sub whatever() current_label_clicked.performClick() End Sub
but you can't do that with labels.
So how do I raise the click event for the label?
Thanks.

John over 10 yearsThanks for the info, but I have several buttons and I do not want a separate function for each button. I am trying to use a single function for all labels and a single variable to reference the one that was clicked. When the "click" subroutine is called, just use whatever label is referenced by the variable and perform a click event for it.

John over 10 yearsThis would work if I could use "...) Handles sender.Click", but that gives me an error.

William Gérald Blondel over 10 yearsIf you have 3 labels name Label1, Label2 and Label3 you can create a Function that handles click on all these labels. ` Private Sub Label_Click(sender As Object, e As EventArgs) Handles Label1.Click, Label2.Click, Label3.Click 'something here End Sub`

John over 10 yearsOK, I figured it out. I can simply leave off the "Handles" statement and it works just as well.

John over 10 yearsApparently, I need to wait 8 hours to post my final code as an answer, but basically I changed my calling routing to be the same as yours (William), but using my own naming convention.
