Seeing the error message:
“ Error returned: ‘The following error occurred while opening the file ‘\ServerName \homes\documents\visual studio 2015\Projects\TabularProject4\TabularProject4\bin\Data\TabularProjecdemo_Table_name.db\Query (13).RowNumber 2662979 (14).0.idf’: The system cannot find the path specified.”
It seems that you are trying to access a file with a user who does not have privileges over that file.
I would check:
1. If this file exists,
2. If the Virtual DataPort server that contains the view can access to it,
3. If the user that is launching the Virtual DataPort server has privileges for the file.
Hope this helps.
