Procedure List

Procedure Name

Type

Description

(Declarations) Declarations Declarations and private variables for the modJetObjectInfo module
BuildDictionaryToArray Procedure Build a dictionary of Data Access Objects to an array. This includes tables, fields, queries, indexes, relations, forms, reports, macros and modules. The array is populated with both the object type and name in the form: [ObjectType][ObjectName]. For example, a table named 'Customers' appears in the array as [Table][Customers].
BuildDictionaryToTable Procedure Build a dictionary of Data Access Objects to a table. This includes tables, fields, queries, indexes, relations, forms, reports, macros and modules. The table populated is named 'tbl_DAO_Dictionary'. If the table doesn't exist, it is created. If it does exist, it is first emptied of records. The array is populated with both the object type and name in the form: [ObjectType][ObjectName]. For example, a table named 'Customers' appears in the array as [Table][Customers].
DumpDAOToText Procedure Dump the DAO structure of the database to a text file. This function creates a text file containing a list of objects in the current database, and optionally, their property names and values. If a path is omitted in the 'strFile' parameter, the file is created in the current directory.
DumpDAOToText_WriteOutput Procedure Write the string out to the file. This is a private helper function used by DumpDAOToText().
DumpDAOToText_WriteProperty Procedure Write the name and value of the supplied property. This is a private helper function used by DumpDAOToText().
GetQueryType Procedure Get the type of the named query: Select, Action, Crosstab, Delete, Update, Append, Make-table, Data-definition, Pass-through, or Union.
IsObjectInDB Procedure Determine if the named object is in the named Jet database.
NumberObjects Procedure Get the number of objects in a database, including tables, queries, forms, reports, macros, modules and relationships. System objects (such as the MSYS... tables) are not counted.
ObjectsToArray Procedure Populate the passed array with a list of object names of the specified type.
ObjectsToString Procedure Populate the supplied string with a delimited list of object names of the specified type.
QueryFieldsToArray Procedure Populate the passed array with a list of fields in the named query.
QueryFieldsToString Procedure Populate the passed string with a list of fields returned by the named query.
QueryParametersToArray Procedure Populate the passed array with a list of parameters returned by the named query.
QueryParametersToString Procedure Populate the passed string with a list of parameters returned by the named query.
RelationFieldsToArray Procedure Populate the passed array with a list of fields in the named relation.
RelationFieldsToString Procedure Populate the passed string with a list of fields in the named relation.
