 |
|
I am using the function FindNeares to search a table by using the text typed
into a TEdit field and it works fine. However, I would like to be able to
detect when the function call can no longer find a match as I am typing in
text and the FindNearest doesn't return anything. Is there a way to do this?

Do a string compare with your AnsiString and your Index Field, and
as soon as the compare does not match, SetFocus to another field, Pop up a
Window with Warning, or whatever you would like.
My suggestion would be to "Build" your Index as you go. I prefer
this method, because it allows for a lot of different errors.
example of Right Padded Index:
Edit1 Your_Info.
AnsiString B
IndexField char 8.
12345678
123
456
876
ABD
B=Your_Info.
do a while statement.
while(B.Length()< B=B+" ";
GotoNearest().
check and see if B is equal to your Table data, if not
pop your window. If so, loop back to your Edit1 input.
