Attaches a data source to the specified publication, which becomes a main publication if it's not one already.
expression.OpenDataSource(bstrDataSource, bstrConnect, bstrTable, fOpenExclusive, fNeverPrompt)
expression Required. An expression that returns a MailMerge object.
bstrDataSource Optional String. The data source path and file name. You can specify a Microsoft Query (.qry) file instead of specifying a data source, a connection string, and a table name string; values in a Microsoft Query file override values for bstrConnect and bstrTable.
bstrConnect Optional String. A connection string.
bstrTable Optional String. The name of the table in the data source.
fOpenExclusive Optional Long. True to deny others access to the database. False allows others read/write access to the database. The default value is False.
fNeverPrompt Optional Long. True never prompts when opening the data source. False displays the Data Link Properties dialog box. The default value is False.
This example attaches the Employees table from the Northwind database and denies everyone else write access to the database while it is opened.
