A text box control is a box in which the user can enter text while the dialog box is displayed. By default, a text box holds a single line of text. Enable support single and multiline text boxes. The last parameter of the textbox function contains a variable to set the textbox style.
Sub Main
MsgBox "This example displays a dialog box that shows the difference between a single-line text box and a multi-line text box"
Begin Dialog TextBoxSample 16,30,180,96,"Text Boxes and Text"
OKButton 125,74,40,14
Text 8,8,32,8,"Single-line Text Box:"
TextBox 8,20,100,12,.TextBox1
Text 8,44,84,8,"Multi-line Text Box:"
TextBox 8,56,100,32,.TextBox2, 1
End Dialog
Dim Dlg1 As TextBoxSample
Button = Dialog ( Dlg1 )
End Sub
