open/save dialog, user clicks cancel

[Guest]

I'm fairly new at this, so sorry if it's a stupid question.

I've used the code from the http://www.mvps.org/access/api/api0001.htm to
create dialog boxes for both importing and exporting data. I have 2
questions, though:
1.) I've had to create 2 separate macros for exports, 1 for csv files and 1
for xls. I've tried putting both in 1 module, but I kept getting errors when
I'd test for both. 1 would usually save np (it varied which one), but the
other format would either do nothing or create an error.
2.) I know there's a way to prevent/hide the error when a user clicks the
cancel button from the dialog box, but my searches have turned up nothing.

Any help is greatly appreciated.

If you are using the API code you downloaded and the user cancels, the call
returns and empty string. Since I don't use macros much, I don't know how
you handle that in a macro. In VBA, you test the return value to see if it
is = ""

Thanks Klatuu, I've found the answers to both (mostly through testing,
although I'm sure the web's riddled with it...I just didn't find it in my
searches).

The code I ended up using to solve both issues is this:

If strSaveFileName = "" Then
MsgBox "Action Cancelled"
Else:
If strSaveFileName Like "*xls" Then
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9,
[TableName], strSaveFileName, True
Else:
DoCmd.TransferText acExportDelim, , [TableName], strSaveFileName, True
End If
End If

For imports, of course, I replaced "strSaveFileName" with
"strInputFileName". I'm really very new at this, and have learned all I know
from this forum, so the code maybe dirty, but it works. Hopefully, this will
prove useful to someone else.
