Text boxes and text

A text box control is a box in which the user can type text while the dialog box is displayed. By default, a text box holds a single line of text. BlueZone Basic supports single and multi-line text boxes. The last parameter of the TextBox function contains a variable to set the TextBox style.

Example:

Sub Main
   Begin Dialog TextBoxSample 16,30,180,96,"Text Boxes and Text"
   OKButton 132,20,40,14
   CancelButton 132,44,40,14
   Text 8,8,32,8,"Text Box:"
   TextBox 8,20,100,12,.TextBox1
   Text 8,44,84,8,"Multiline Text Box:"
   TextBox 8,56,100,32,.TextBox2
End Dialog
   Dim Dlg1 As TextBoxSample
   Button = Dialog ( Dlg1 )
End Sub

The above code produces the following dialog:

The following is an additional example of how to implement a multi-line text box:
