LineCount, TextLength Properties Example

The following example counts the characters and the number of lines of text in a TextBox by using the LineCount and TextLength properties, and the SetFocus method. In this example, the user can type into a TextBox, and can retrieve current values of the LineCount and TextLength properties.

To use this example, copy this sample code to the Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains the following controls:

• A TextBox named TextBox1.
• A CommandButton named CommandButton1.
• Two Label controls named Label1 and Label2.

'Type SHIFT+ENTER to start a new line in the text box.

Dim CommandButton1
Dim TextBox1
Dim Label1
Dim Label2

Sub CommandButton1_Click()
    'Must first give TextBox1 the focus to get line count
    TextBox1.SetFocus
    Label1.Caption = "LineCount = " & TextBox1.LineCount
    Label2.Caption = "TextLength = " & TextBox1.TextLength
End Sub

Sub Item_Open()
     Set TextBox1 = Item.GetInspector.ModifiedFormPages.Item("P.2").Controls("TextBox1")
     Set Label1 = Item.GetInspector.ModifiedFormPages.Item("P.2").Controls("Label1")
     Set Label2 = Item.GetInspector.ModifiedFormPages.Item("P.2").Controls("Label2")
     Set CommandButton1 = Item.GetInspector.ModifiedFormPages.Item("P.2").Controls("CommandButton1")

    CommandButton1.WordWrap = True
    CommandButton1.AutoSize = True
    CommandButton1.Caption = "Get Counts"

    Label1.Caption = "LineCount = "
    Label2.Caption = "TextLength = "

    TextBox1.MultiLine = True
    TextBox1.WordWrap = True
    TextBox1.Text = "Enter your text here."
End Sub
