Trimming a label - brandonio21 - 06-28-2012

I was contacted the other day asking to hand over a code snippet that trimmed a label if it was too long, making it display "...". So, I crafted a method that would do so!

Code:
'This method is intended to trim a label that is too long and replace it with

    'dots where there would normally be stuff

    'Made by Brandon Milton, http://brandonsoft.com

    Public Sub TrimLabel(ByVal label As Label, ByVal MaxCharCount As Integer)

            If (label.Text.Length > MaxCharCount) Then

                Dim remaining As Integer = label.Text.Length - MaxCharCount

                label.Text = label.Text.Remove(MaxCharCount - 4, 4 + remaining)

                label.Text = label.Text & "..."

            End If

    End Sub

Usage:

Code:
Dim Label As New Label

Label.Text = "Hello my name is Brandon"

TrimLabel(Label, 10) 'Trims to a max of 10

MsgBox(Label.Text)

With this usage, the output displayed is Hello ... which was trimmed from the original "Hello my name is Brandon"

I just stumbled upon this post and when I saw the code, it reminded me on something.

Quote:Public Sub TrimLabel(ByVal label As Label, ByVal MaxCharCount As Integer)

Does "ByVal" means decalring a parameter for method? Like in Java?

Would it be something like this in Java?

Code:
public void TrimLabel(label Label, int MaxCharCount){

//code

}

(Even though I am not sure if type label exists. I assume it would be JLabel or something.)

This is exactly right! Of course, I don't think that ByVal is completely necessary in VB.NET. For example, I think the code snippet

Code:
Public Sub TrimLabel(label As Label,MaxCharCount As Integer)

Would also work.

But yes, you are right!
