[RESOLVED] [VS2005/CE] How to determine is mouse click was on a label

[szlamany]

I'm believe that labels cannot receive click events - right?

How would I determine if a mouse-click on a form (when checked in the FORM click event - I guess) was over a specific label?

I'm not sure what version of .NET your using but 2003 has a click event for a label.

Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
'...Enter your code
End Sub

They sure can, when you are in the form designer look to the top of the properties box, (not sure if that is the correct term but you know, the place where you type the name and the text of the label) There is little icon that looks like a lighting bolt. click that you will see all the events you can associate things with. There all all kinds of choices from hover to click.

Hopefully I have answered you question.

Sorry about that - I should have indicated the version...

VS2005

and the worse part - Mobile CE app - there is no click event for a label.

I really can't check because I cannot run the program on the computer but could you do something like this?

Private Sub Form1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click
        If sender.ToString() = "Label1" Then
 
        End If
End Sub

Nope - SENDER.TOSTRING returns APC.APC - which is the project and form name.

Somehow I think I have to use the MOUSEPOINTER - but it's not aligning sensibly with the TOP/LEFT/HEIGHT/WIDTH of the label.

Well I know a really crappy way to do it.. but I know you won't like it. I have an idea though, so hold on

[Fromethius]

Nevermind, I have no clue. lol

Ok - I'm trying to use MOUSEPOSITION.X and .Y in the FORM_CLICK event and comparing it to a LABEL TOP/LEFT/WIDTH and HEIGHT.

And apparently the MOUSEPOSITION includes the "top line" of the form but the x/y of the label does not include that area.

Any ideas on how to measure or realize the size of the top bar on the form?

Maybe this can help http://www.vbforums.com/showthread.php?t=455971. This thread shows how to add a click event to a rectangle, so perhaps you could draw a rectangle where your label is and then monitor the click event for the rectangle.

I started using the MOUSEDOWN event - it's working much better.

    Private Sub APC_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Click
        Label.Text = MousePosition.X.ToString & " " & MousePosition.Y.ToString
    End Sub

    Private Sub APC_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
        lblStatus.Text = e.X.ToString & " " & e.Y.ToString
    End Sub

The _CLICK takes into account the "top bar" and the _MOUSEDOWN is the useable area of the FORM - and that's what the label placement is based on.
