Echo Action [Access 2003 VBA Language Reference]

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

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 window. 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."

Remarks

When Microsoft Access 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, Microsoft Access automatically turns echo back on and repaints the window. The No setting for the Echo On argument doesn't affect 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 these to gather or display information even if echo is turned off. To turn off 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 Hourglass action to change the mouse pointer into an hourglass icon (or whatever mouse pointer icon you've set for "Busy" in Microsoft Windows 2000 or Microsoft Windows XP) to provide a visual indication that the macro is running.

To run the Echo action in Visual Basic, use the Echo method of the DoCmd object.

Examples

The following macro opens the Add Products form from a button on the Suppliers form. It shows the use of the Echo, Close, 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. Then the GoToControl action 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.
