MobileAsset v7: Nothing happens at Print Preview of Asset Tag, Labeler's Data tab says "The connection to <MobileAsset> is not valid."

Scott Leonard
2023-01-19
in Version 7

Symptoms

  • In MobileAsset, when Print Previewing an asset tag, no preview window appears, and no error appears on screen. MobileAsset.log contains errors regarding "Input string was not in a correct format" (full error below).

  • You can configure the ODBC connection and Labeler's data connection successfully, but the Data tab still says "The connection to <MobileAsset> is not valid. To check the connection properties, click Edit Connection. To delete this data source connection and create a new one, click Remove Connection."

  • Clients on workstations and the database PC experience the same thing.

Cause

In SQL, the AssetReader accounts's db_datareader checkbox is unchecked for the WaspTrackAsset database.
