Application.Echo method (Access)
The Echo method specifies whether Microsoft Access repaints the display screen.
expression.Echo (EchoOn, bstrStatusBarText)
expression A variable that represents an Application object.
|EchoOn||Required||Integer||True (default) indicates that the screen is repainted.|
|bstrStatusBarText||Optional||String||A string expression that specifies the text to display in the status bar when repainting is turned on or off.|
If you are running Visual Basic code that makes a number of changes to objects displayed on the screen, your code may work 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 should not or does not need to see.
The Echo method does not suppress the display of modal dialog boxes, such as error messages, or pop-up forms, such as property sheets.
The Echo method doesn't affect the visibility of the ribbon or the availability of ribbon commands.
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. You may want to create a macro that turns repainting on and then 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 the code, you won't be able to see progress through the code or any other visual cues until repainting is turned back on. However, your code will continue to execute.
Do not 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.
The following code 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 indicating 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.
Public Sub EchoOff() ' Open the Employees form minimized. Application.Echo False DoCmd.Hourglass True DoCmd.OpenForm "Employees", acNormal DoCmd.Minimize Application.Echo True DoCmd.Hourglass False End Sub
