Hy,

is it possible to change the fieldwidth of an StringField at runtime ?
I have now a width of 8 and want to change at runtime to a width of 20.
!! the current data in the fields must be saved!

I tried =>>  "Field->DisplayWidth = 20"
I tried "EditRange... "

-->  but nothing happends!

Anyone an idea ?

Thanks..

Joachim

YES, I found the trick!!!!!!!!!!!

==>
The easiest way is to use the SQL ALTER TABLE statement as described in the
Local SQL help file in your BDE directory. The other way is to use the BDE
API function DbiDoRestructure. See the examples at
www.borland.com/devsupport/bde/bdeapiex.
