Excel vba stop screen updating
You may have noticed that when running the procedure with screen updates disabled the subroutine appeared to run faster.This should certainly be the case as Excel doesn't have to continually redraw the screen each time something changes.To achieve this we need to add a single line of code to the subroutine, just below the variable declarations.It's probably also worth changing the colour that we're using so that we can see when things have changed. This time you won't be able to see the macro carrying out its tasks; once the subroutine has finished the screen will update once at the end to show you the final result.The Screen Updating property resets at the end of a procedure.This means that if you run a different subroutine after the one above and you haven't added the line of code to disable screen updates to it, you'll be able to see the screen updating in the background.This screen update takes extra time and is usually unnecessary.The good news is that 99% of the time, the Select method can be avoided all together.
The general structure of our timer is shown below: This isn't the most accurate timer system you can create in VBA but it's good enough for our example.Jeff Coachman The After Update event does not trigger when the field is changed by vba. Hwnd To "unfreeze", call it again with an argument of 0 (zero): Lock Window Update 0 Just be SURE to call the unfreeze code, otherwise it'll appear to lock up the application. Recordset Dim var New Value As Variant Set rst = Me. [Tag_Create S I've tried the revised recordset code. As you suggested, I started to look at form events but could find nothing causing a problem.The flicker is bearable, but I very much don't like it at all. Attach a label to a control 1) Open a form, report, or data access page in Design view. I have commented out the last 3 lines of the code (see code) Nothing has changed really. Now that the 3 last lines of the code have been commented out, there is no screen flicker. docmd For clarity, note that [Stocknum] is a field in the same record. So, I created a new access database and included only the table and the continuous form stripped everything. Thank you The code you have there should eliminate the flicker... I hate using "Null" as a selection/option Lets see if another expert has more insight into this... So if I wanted to lock the screen from a button click on a Form, I'd do this: Lock Window Update Me. It is awesome to be getting the caliber of help that is available here. That may be taken care for by controlling Painting: Private Sub Flip Tag() Dim rst As DAO. I have asked a similar question in the past and received answers that minimized the flicker, but I really hope that you can help me eliminate the screen flicker when changing a value of a field in an existing record using VBA. Echo True Try putting the code on the After update even instead of the click event... Other: Then if only two states are allowed for this field, I would use a Boolean field and set a default value. I am hoping that this issue can be solved completely and without reservation. To do that, in a Standard Module add this to the General Declarations section: Declare Function Lock Window Update Lib "user32" (By Val hwnd As Long) As Long You can then use that function like this: Lock Window Update Where 'h Wnd' is the Windows Handle of the form you wish to "freeze". The following code (my code) works perfectly though. I have tried LSMConsulting's advice and it does work as advertised. When run, it reads the correct data but only updates the first record every time. Before I decide on the solution, I thought that I might give Cactus_Data an opportunity to address these problems. Update Set rst = Nothing End Sub If the screen flickers by this, something else is going on, like running (other) Before/After Events or format conditions.
