SYMPTOMS
Pressing the ESC key before pressing the ENTER key when the insertion point is in a text box, clears the content of the text box. However, doing the same thing in a combo box does not produce the same behavior.



CAUSE
The ESC key is seen as a cancel operation for a text box object. In the combo box object, the ESC key is a terminator for the drop-down list only.



WORKAROUND
In the text box object, it is possible to use the Keypress event to trap for the ESC key. If the ESC key is pressed, a dialog box prompting the user to save the data can be displayed. Please see the "Step-by-Step Example" section of this article.



STATUS
This behavior is by design.



MORE INFORMATION
The following example creates a form with a text box, and traps for the ESC key in the text box. When the escape key is pressed, a dialog is displayed, and if the user answers No, the data is not cleared from the text box.

Step-by-Step Example
 Create a form. Place a text box on the form.  Place the following code in the Keypress event handler: * Visual FoxPro Header file. This file contains named constants for many * Visual FoxPro functions #INCLUDE "FOXPRO.H"  IF nkeycode = 27  && The escape key is pressed. nresponse=MESSAGEBOX("Do you want to Cancel?", MB_YESNO) IF nresponse=IDNO NODEFAULT ENDIF ENDIF  Save and run the form. When the form displays, type something in the text box. Then press the ESC key.
