Most of the functionality available in Microsoft Access can be called from an external program, such as one written in Visual Basic 6 or Excel. This class contains methods and properties that show you how to get to database objects in a Microsoft Access database.
Procedure Name | Type | Description |
(Declarations) | Declarations | Declarations and private variables for the CAccessAutomation class. |
AppAccess | Property | Handle to the Access application. |
AccessPath | Property | Path where Access is installed. |
AccessVersion | Property | Access Version number. |
Visible | Property | Get the visible property of the current instance of Access. |
WorkgroupPath | Property | The workgroup information file contains security definitions of users, groups and permissions for Access and Jet databases. |
Class_Terminate | Terminate | Clean up. |
StartAccess | Method | Starts an instance of Access without opening a database; not needed if the OpenDatabase function is called. |
OpenDatabase | Method | Open the specified database in the current instance of Access. |
OpenTable | Method | Open the specified table. |
OpenQuery | Method | Open the specified query. |
OpenForm | Method | Open the specified form. |
OpenReport | Method | Open a report in design, preview, or report view mode. Also print it. To specify a range of pages to print, use the ReportPrintPages procedure instead. |
ReportPrint | Method | Print an entire report. To specify a range of pages to print, use the ReportPrintPages procedure instead. |
ReportPrintPages | Method | Print a range of pages from a report. |
CloseAccess | Method | Close the instance of Access. |
CloseDatabase | Method | Close the current open database. |
CloseObject | Method | Close an object. |
DeleteObject | Method | Delete the named object from the database. |
DuplicateObject | Method | Duplicates (copies) the specified object to a new name (an object with the new name must not already exist). |
ExecuteSQL | Method | Executes an action query represented by a SQL string. |
ExportObject | Method | Exports the named object from the current database to another database in the specified format. |
ImportObject | Method | Imports the named object into the current database. |
TableToXML | Method | Export data from a table or query to an XML file. |
ReportOutput | Method | Export a report to a file such as a PDF, XPS, HTML, Snapshot, etc. |
ReportOutputPDF | Method | Export a report to a file in PDF format. |
