PRB: DEL Key Behavior Depends on Text Box MultiLine Property

ID: Q77737

The information in this article applies to:

- Standard and Professional Editions of Microsoft Visual Basic for

  Windows, versions 2.0 and 3.0

- Microsoft Visual Basic programming system for Windows, version 1.0

SYMPTOMS

Pressing the DEL key in a multiline text box generates a KeyPress event for that text box with an ASCII code of 8 for the key. In a standard text box, no KeyPress event is generated for the DEL key.

STATUS

This behavior is by design. It is inherent to Windows and is not specific to Microsoft Visual Basic for Windows.

MORE INFORMATION

Steps to Reproduce Behavior

1. Place a text box on a form.

2. Set the MultiLine property for the text box to True.

3. Add the following code to the text box KeyPress event:

   Sub Text1_KeyPress (keyAscii as Integer)
        debug.print keyAscii  ' This will print the generated ASCII
                              ' code to VB's Immediate window.
   End Sub

4. Execute the program and press the DEL key while the focus is on the

   text box. An "8" will be printed in the Immediate window.

If the text box's MultiLine property is set to false, no KeyPress event occurs and nothing is printed to the Immediate window when you press the DEL key. This behavior is standard for Windows multiline text boxes.
