Need a Delete Button?

[Mike]

On my form I have an button to Browse my Computer and an Open Button
that allows me to open the file I have associated on my Computer. The
browse button also places the name of the file into a a field named
tbFileName on my form.

My question is, once I associated this file there is no way to
unassociate it on this form. Is there a way to delete this with a
delete button?

Here is my code. Any help would greatly be appreciated. Thanks.

You could set tbFile = "", but it looks like you're trapping that as an
error.

What do you mean by "unassociate it on this form"? Remove the value from
tbFileName, or something else?

 

[Mike]

I know my terms are not correct. I just do not want the form showing
the name of a file if I mistakenly associate/ link it. See once I find
the file I want and click OPEN. The file parses itself to the file name
and deletes the rest of the path. But sometimes I attach/associate/link
the wrong file and then I want to be able to DELETE it, so it does not
show the file name. Can someone help me delete it from the form.

Make Sense? I wish I could show you with a picture.

Sorry, it still doesn't make sense to me.

You're putting the file name in the field named tbFileName on your form. Are
you saying that you want to remove that name from that field? Add a button
to your form, and put Me.tbFileName = Null in the Click event.

I suspect you are confusing the issue by focusing on the Form... Forms are
for entering and displaying data that is stored in Tables and retrieved with
Queries. (Forms can be "unbound" for other purposes, but yours does not seem
to be unbound, from what you say.)

My guess is that you are having difficulties because the information you
entered on the Form is already saved to the Table, and what you really need
to do is to delete the Record from the Table.

Do you sometimes discover the error after closing the data entry Form, and
then want to delete it? If so, you will have to remove the Record from the
Table, not just the value from the Form.
