Echo Method (Application Object)

Applies To Application object.

Description

The Echo method specifies whether Microsoft Access repaints the display screen.

Syntax

Application.Echo echoon[, statusbartext]

The Echo method has the following arguments.

Argument	Description

echoon	True (default) indicates that the screen is repainted; False indicates that the screen isn't repainted.
statusbartext	A string expression that specifies the text to display in the status bar when repainting is turned on or off.

Remarks If you are running Visual Basic code that makes a number of changes to objects displayed on the screen, your code may be faster if you turn off screen repainting until the procedure has finished running. You may also want to turn repainting off if your code makes changes that the user shouldn't see or doesn't need to see.

The Echo method doesn't suppress the display of modal dialog boxes, such as error messages, or pop-up forms, such as property sheets.

If you turn screen repainting off, the screen won't show any changes, even if the user presses CTRL+BREAK or Visual Basic encounters a breakpoint, until you turn screen repainting back on. You may want to create a macro that turns repainting on and assign the macro to a key or custom menu command. You can then use the key combination or menu command to turn repainting on if it has been turned off in Visual Basic.

If you turn screen repainting off and then try to step through your code, you won't be able to see your progress through the code, or any other visual cues, until repainting is turned back on. However, your code will continue to execute.

Note Don't confuse the Echo method with the Repaint method. The Echo method turns screen repainting on or off. The Repaint method forces an immediate screen repainting.

Example

The following example uses the Echo method to prevent the screen from being repainted while certain operations are underway. While the procedure opens a form and minimizes it, the user only sees an hourglass icon to indicate that processing is taking place, and the screen isn't repainted. When this task is completed, the hourglass changes back to a pointer and screen repainting is turned back on.

Sub EchoOff()
    Application.Echo False
    DoCmd.Hourglass True
    DoCmd.OpenForm "Employees", acNormal
    DoCmd.Minimize
    Application.Echo True
    DoCmd.Hourglass False
End Sub
