Echo Macro Action
You can use the Echo action to specify whether echo is turned on. For example, you can use this action to hide or show the results of a macro while it runs.
Setting
Note
This action will not be allowed if the database is not trusted. For more information about enabling macros, see the links in the See Also section of this article.
The Echo action has the following arguments.
Action argument |
Description |
|---|---|
Echo On |
Click Yes (turn echo on) or No (turn echo off) in the Echo On box in the Action Arguments section of the Macro Builder pane. The default is Yes. |
Status Bar Text |
The text to display in the status bar when echo is turned off. For example, when echo is turned off, the status bar can display "The macro is running." |
When runs a macro, screen updating often shows information not essential to the functioning of the macro. When you set the Echo On argument to No, the macro runs without updating the screen. When the macro finishes, Access automatically turns echo back on and repaints the window. The No setting for the Echo On argument doesn't affect the functionality of the macro or its results.
The Echo action doesn't suppress the display of modal dialog boxes, such as error messages, or pop-up forms, such as property sheets. You can use dialog boxes and pop-up forms to gather or display information, even if echo is turned off. To suppress all message or dialog boxes except error message boxes and dialog boxes that require the user to enter information, use the SetWarnings action.
You can run the Echo action more than once in a macro. This allows you to change the status bar text while the macro runs.
If you turn echo off, you can use the DisplayHourglassPointer action to change the mouse pointer into an hourglass icon (or whatever mouse pointer icon you've set for "Busy") to provide a visual indication that the macro is running.
To run the Echo action in a Visual Basic for Applications (VBA) module, use the Echo method of the DoCmd object.
Examples
Set the value of a control by using a macro
The following macro opens the Add Products form from a button on the Suppliers form. It shows the use of the Echo, CloseWindow, OpenForm, SetValue, and GoToControl actions. The SetValue action sets the Supplier ID control on the Products form to the current supplier on the Suppliers form. The GoToControl action then moves the focus to the Category ID field, where you can begin to enter data for the new product. This macro should be attached to the Add Products button on the Suppliers form.
