Connects to an SQL Compact Edition 3.5 database. Assumes the database has a blank password.

Connects to an SQL Compact Edition 3.5 database.

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Returns an instance of an object from the collection using a distinct value (see IDatabaseObjects.DistinctFieldName). If the collection has implemented the IDatabaseObjects.Subset function then the objDistinctValue need only be unique within the collection's subset, not the entire database table.

Returns an object from the collection using a unique key value. The key must be unique within the collection. If the collection's IDatabaseObjects.Subset has been implemented then the key need only be unique within the subset specified, not the entire database table.

Returns an object from the collection using a unique key value. The key must be unique within the collection. If the collection's IDatabaseObjects.Subset has been implemented then the key need only be unique within the subset specified, not the entire database table. Returns Nothing/null if the object does exist with the specified key. This feature is what differentiates Database.ObjectByKey() from Database.ObjectByKeyExists().

ObjectByOrdinalFirst returns the first object in the collection respectively filtered and sorted by the collection's IDatabaseObjects.Subset and IDatabaseObjects.OrderBy values. It differs from ObjectByOrdinal in that it only loads the first record from the database table not the entire table.

Returns the last object in the collection respectively filtered and sorted by the collection's IDatabaseObjects.Subset and IDatabaseObjects.OrderBy values. It differs from ObjectByOrdinal in that it only loads the first record from the database table not the entire table.

Deletes an object's database record. If the collection's IDatabaseObjects.Subset has been implemented then the object must exist within the subset, otherwise the object will not be deleted. If the object has not been saved to the database the function will exit without executing an SQL DELETE command. After deleting the database record the object is set to Nothing. The calling function should receive the object ByRef for this to have any affect. Setting the object to Nothing minimises the possibility of the deleted object being used in code after ObjectDelete has been called.

Returns whether the key exists within the collection. If the collection's IDatabaseObjects.Subset has been set then only the subset is searched not the entire table.

Returns whether an object exists for the specified distinct value in the collection.

Returns the database fields for an object from the collection using a distinct value (see IDatabaseObjects.DistinctFieldName). If the collection has implemented the IDatabaseObjects.Subset function then the objDistinctValue need only be unique within the collection's subset, not the entire database table. This is typically used to interogate the database fields before loading the object with a call to ObjectFromFieldValues. This function is rarely used and generally the Object function suffices.

Gets and returns the field value from the database record associated with the object and collection.

Gets and returns the field value from the database record associated with the object and collection.

Returns an instance of an object from the collection using a distinct value (see IDatabaseObjects.DistinctFieldName). If the collection has implemented the IDatabaseObjects.Subset function then the objDistinctValue need only be unique within the collection's subset, not the entire database table. Returns Nothing/null if the distinct value does not exist in the database. This feature is what differentiates Database.Object() from Database.ObjectIfExists().

Locks the database record associated with this object by selecting and locking the row in the database. Supported in Microsoft SQLServer, Pervasive and MySQL. The record lock is released when the transaction is committed or rolled back. Throws an exception if not in transaction mode. Returns the field values from the record that has been locked.

Returns an array of IDatabaseObject objects contained within this collection.

Extracts the fields to save to the database from the objItem.SaveFields function. The fields are then written to the database using either an SQL INSERT or UPDATE depending on whether the object has already been saved. If the collection has implemented IDatabaseObjects.KeyFieldName then objItem's key is also validated to ensure it is not null and unique within the collection. If objCollection has implemented IDatabaseObjects.Subset then objItem should exist within objCollection. If not, a duplicate key error may occur if the obItem's key is being used in another subset in the same table. If a record is being amended (IDatabaseObject.IsSaved returns true) then the function will "AND" the collection's IDatabaseObjects.Subset conditions and the objItem's IDatabaseObject.DistinctValue value to create the WHERE clause in the UPDATE statement. Therefore, the combination of the IDatabaseObjects.Subset and IDatabaseObject.DistinctValue conditions MUST identify only one record in the table. Otherwise multiple records will be updated with the same data. If data is only inserted and not amended (usually a rare occurance) then this requirement is unnecessary.

Returns the number of items in the collection. If the collection's IDatabaseObjects.Subset has been implemented then this function returns the number of records within the subset, not the entire table. Also utilises the table joins so that any filters specified on the subset can be used.

Deletes all of the objects in the collection. If IDatabaseObjects.Subset has been implemented then only the objects within the subset are deleted, not the table's entire contents.

Returns an IDictionary object. Each key/value pair contains a key and the object associated with the key.

Returns an IDictionary object. Each key/value pair contains a distinct value and the object associated with the distinct value.

Sets the field value for the database record associated with the object and collection.

Sets the field value for the database record associated with the object and collection.

Returns an IList object containing all of the collection's associated child objects. This function is useful when loading a set of objects for a subset or for use with the IEnumerable interface.

Returns a collection of objects that match the specified search criteria. This function utilises any subsets, ordering or table joins specified in the collection. To add a set of conditions to the objSearchCriteria object with higher precendance use the "Add(SQLConditions)" overloaded function as this will wrap the conditions within parentheses.

Returns a String that represents the current Object.
