Thank you, Steve, but FldDirty() does not help me. FldDirty() returns true after the field has been modified, even if undo is not available.
For example, --- 1. One character is entered 2. The character is deleted by backspace 3. Undo (The character is restored) 4. Undo is not available here, but FldDirty() returns true. --- At Sun, 23 Nov 2003 22:39:33 +0100 "steve" <[EMAIL PROTECTED]> wrote: >Date: Sun, 23 Nov 2003 22:39:33 +0100 >From: "steve" <[EMAIL PROTECTED]> >Reply-To: "Palm Developer Forum" <[EMAIL PROTECTED]> >To: "Palm Developer Forum" <[EMAIL PROTECTED]> >Subject: RE: How do I know whether undo is available? > >Perhaps the dirty bit can help you: FldDirty() > Subject: How do I know whether undo is available? >> >> Hello, >> >> I am writing an application that has an field, which user can >> edit arbitrarily.
