Problems after linking to tables over WAN

C

CB

Hi Doug,

I changed the code from the link you provided to the following. To make it
easier to see, look for "##### my comments #####." Note that I only commented
out code rather than deleting anything in the event I made an error.

I also have a nagging feeling that I don't have this code in the right
place. I'll ask that one after I get rid of compile errors.

Thanks again for your patience!

Chris

Since you know that the path exists, eliminate the code

If Len(Dir(strDBPath)) = 0 Then
'File Doesn't Exist, call GetOpenFileName
strDBPath = fGetMDBName("'" & strDBPath & "' not found.")
If strDBPath = vbNullString Then
'user pressed cancel
Err.Raise cERR_USERCANCEL
End If
End If

Hi Doug,

It works like a charm! As to my previous comment where I thought I might not
have the code in the right place, I figured out my own answer. Though I
placed the code in the form's class modue, I wasn't calling it from the On
Open event procedure. Once I found the proper syntax, all is okay.

Thanks for all your help!

Hi all,

I would like to thank everyone for all their assistance. After all this
frustration, it turned out to be permissions after all in the end. All is not
lost though, as I've learned useful new stuff. :)

I had permissions issues previously (BE permissions not the same as FE) and
was certain that I had fixed all those. However, somehow in the FE MDE file
the Full Data users no longer had Insert permissions. I guess double- and
triple-checking isn't sufficient. :(
