Alarm & Event Query To Spreadsheet.vi

Question

dear all,
 i m using  "Alarm & Event Query To Spreadsheet.vi" for alarm transfer using following inputs
1. Filter
2.Display Format
3. Output file path(C:\Program Files\National Instruments\LabVIEW 7.1\*.ALR)
and Database URL it will take by default i.e current tagfile.scf
on running this i get following error
"HIST_AlarmsToSpreadsheet.vi, Citadel:  (Hex 0x8ABC1008) Read alarm failed because of connection or query failure."
if i give the database URL manually in the following way
\\computer name\Labview
then i get the following error out
"HIST_AlarmsToSpreadsheet.vi, IAK_SHARED:  (Hex 0x8ABC700A) Not found."
so pls solve my problem as early as possible for u

Hi dhanwanti,
There could be a couple possibilities here -- one is that the database you are trying to reference has become disconnected -- Make sure you can see historical data in MAX.  If needed, reconnect your database or create a new one and change this in the .scf file in the Tag Configuration Editor.
Another possibility is that some of the parameters you have set in the filtering could be incorrect such as start and stop time.  I would suggest creating a simple test VI to make sure you can get the Alarm & Event Query To Spreadsheet.vi working, and then double check how it integrates into your project.   You may also want to take a look at the example that ships with the DSC Module for this VI, found in the Example Finder under Toolkits and Modules » Datalogging and Supervisory Control » Alarms and Events » Export Alarms to File.VI.
