Definition
VBA ScreenUpdating is a property in Excel Visual Basic for Applications (VBA) that controls the display of changes made in a spreadsheet during the execution of a macro. When set to ‘False,’ it turns off screen updating, which can speed up a macro’s performance by avoiding unnecessary screen refreshes. When set to ‘True,’ it allows the spreadsheet to visually update to reflect changes during macro execution.
Key Takeaways
- VBA ScreenUpdating is a property in Excel VBA (Visual Basic for Applications) which provides a graphical display of any macro commands that run on the Excel screen. Setting this property can have considerable effect on the speed of your macro execution.
- When the VBA ScreenUpdating property is set to false, the screen doesn’t refresh during macro execution, hence speeding up tasks. It essentially turns off the screen updating, enhancing the performance especially for large datasets or complex manipulation.
- Though VBA ScreenUpdating makes the macro run faster, it should be used carefully to avoid disorienting effects. After setting ScreenUpdating property to false, it is crucial to reset it back to true at the end of the macro to reflect all the changes made by your macro.
Importance
VBA ScreenUpdating is a crucial finance term used in Excel VBA programming.
It’s primarily a property utilized to manage the visuals on the screen while running a macro.
Essentially, when ScreenUpdating is set to false, it switches off the screen updating process, making the macro operation invisible to the user, thereby enhancing the speed of code execution.
This is particularly important in finance, as macros often handle large sets of data or perform complex calculations, and the updating of the screen can considerably slow down the procedures.
In other words, VBA ScreenUpdating makes the computational process more efficient and smoother, reducing the waiting time for the user and providing a better overall performance for Excel-based financial modeling and analysis.
Explanation
VBA ScreenUpdating is a property used in Microsoft Visual Basic for Applications (VBA) programming, mainly within Microsoft Excel, to control the way the screen updates or refreshes during the execution of a macro. When set to False, ScreenUpdating tells Excel to not update the screen, leading to the user not seeing any changes on their screen until ScreenUpdating is reset back to True.
The main purpose of this property is to maximize efficiency and speed when running complex or long procedures, as turning off screen updating can significantly improve macro performance. By using VBA ScreenUpdating, a programmer can make a script run more efficiently by preventing unnecessary screen refreshes that do not affect the final outcome but consume system resources and can slow down macro runtime.
Without it, Excel will render every change your code makes, which could be detrimental to performance for large or complex macros. Therefore, VBA ScreenUpdating is heavily used in Excel macros where multiple actions are being performed successively, and the immediate visual updates are not required.
After the procedure is done, ScreenUpdating can be set back to True to allow the user to see the final results and any changes in their workbook.
Examples of VBA ScreenUpdating
The term “VBA ScreenUpdating” refers to a property used in Excel Visual Basic for Applications (VBA) to control the display of your spreadsheet during macro operations. Turning off ScreenUpdating can speed up macro execution and prevent distracting flickers. Here are three real world examples:
Data Importing: Many businesses require regular data updates in their Excel reports for decision making. These data often come from external sources such as web or other databases. A VBA macro can be written to import the data and update the report. During this process, to increase the speed and reduce the system load, ScreenUpdating property can be set to false.
Financial Modeling: Financial analysts often develop large and complex financial models in Excel. These models may include macros that perform iterative calculations or simulations. To prevent the screen from flickering and the model from appearing to run slowly, they can turn off ScreenUpdating while the macro runs, and then turn it back on afterwards.
Customer Relationship Management: A company may use Excel to keep track of customer information, sales data, and trends. Macros might be used to sort, filter, and analyze the data. VBA ScreenUpdating can be turned off to speed up these operations and provide a smoother user experience.
VBA ScreenUpdating FAQ
1. What is VBA ScreenUpdating?
VBA ScreenUpdating is a property used in Excel Visual Basic for Applications (VBA) to control the display of the screen during macro operations. When set to False, the screen does not refresh or show changes until the macro finishes running, which can enhance performance for large or complex operations.
2. How do I use ScreenUpdating in VBA?
To use ScreenUpdating in VBA, you should set the ScreenUpdating property to False at the beginning of your macro, perform your operations, and then set ScreenUpdating back to True at the end of the macro. This looks like:
Application.ScreenUpdating = False
‘ Your code here
Application.ScreenUpdating = True
3. Why should I use ScreenUpdating in my VBA code?
Using ScreenUpdating in your VBA code can significantly improve the speed and performance of your macros, especially for larger tasks or operations. It also provides a smoother user experience by preventing screen flickering or flashing during macro execution.
4. Can I use ScreenUpdating in other VBA applications?
While ScreenUpdating is a property mostly used in Excel VBA, it can also be used in other Microsoft Office applications, such as Word and Access, to control screen refresh during VBA operations in those environments.
5. What happens if I forget to set ScreenUpdating back to True at the end of my code?
If you forget to set ScreenUpdating back to True at the end of your code, the user’s screen will not update to reflect changes made after the macro finishes running. This might confuse users or give the illusion that the application is not responding, even though it’s processing normally. Therefore, it’s always recommended to return ScreenUpdating to its default state (True) when your operations are done.
