Vba screen updating off
The procedure pauses code execution for a certain amount of time putting the whole processes in a type of coma.It is one of the most popular approaches to pausing code execution, and at the same time simplest one.Now why would we want to use the Do Events function you might ask? Wait does not allow you to wait for intervals shorter than 1 second? Need to wait for 500 milliseconds – no more no less? On the other hand Sleep freezes your application entirely although being more granular. Do Events is especially useful when you have a lot of computations going on but want to keep your VBA Project responsive WITHOUT introducing significant (1 second) delays. Want to pause for a minimal interval just to refresh your application screen? Wait Date Add("s", 90, Now) ' = 60 30 'Wait for 1 hour 2 minutes and 30 seconds Application.Wait Date Add("s", 3750, Now) ' = 3600 120 30 at any time and resume control over your project.
Wait Date Add("h", 1, Now) 'Wait for 1 minute 30 seconds Application.Do remember, however, that during macro execution no changes can be undone ( will not undo changes made during macro running).What is more Application Wait does not allow you to wait for periods shorter than a single second. Wait function is: This approach is of course less practical as usually you want to wait simply for a precise interval of time, like say 3 seconds.The next time we run the procedure we don't want to be able to see the screen flickering in the background.
To achieve this we need to add a single line of code to the subroutine, just below the variable declarations.This means that you cannot continue working on your spreadsheet and that Sleep is not to be used for long durations of time as in some extreme cases might cause Excel to assume the application has crashed. As opposed to VBA Sleep, the Application Wait procedure does not freeze Excel during the pause.
