Using Data Controls and Nulls
Posted on 1998-07-16
Hi. I have created a simple application. It has a dBase database with only 2 fields. Name, and age. Name
is a text field, and age is a numeric field. On my VB app, I have a data control linked to the database, and two text boxes linked to the fields. I have another button labeled Update. When I run the program, I use my data
control to move through the records. But, if I stop on a record, and delete the age that was there, and hit my update button, it gives me a data conversion error, because I'm not storing a numeric value in the age field. How can I
make my program allow storing of empty strings in a numeric field???
