Hi arage,
I'm not sure what you mean by the set import dialog box but it sounds like this is a common dialog control.
Maybe you can create your own set import dialog by adding a common dialog control from the "include activex control" option.
You can then set the dialog to look in a certain directory for a certain file etc.
If this is what you are looking for I can give you more info on the common dialog if need be.
HTH
