How To Use Screenupdating Application In Vba?

Excel VBA ScreenUpdating

When we run any VBA macro with a huge set of code, the code completes but in the background we get processing data in the form of running or waiting for the pointer. And once it is done, we can only see the output. The regular way is not the proper way to see how the values are updating by running code. For example, let’s say we have written the code to generate some numbers in 100 cells. Now that code could simply generate the output without showing how the numbers are getting printed. To resolve this, we have VBA ScreenUpdating. ScreenUpdating in VBA helps us the see how the code is generating the output. This could be numbers, text, alphabets or combination. Once we run the code loop, by VBA ScreenUpdating we could able to see the numbers getting generated.

How to Use ScreenUpdating Application in Excel VBA?

We will learn how to use the ScreenUpdating application in Excel by using the VBA Code.

Watch our Demo Courses and Videos

Valuation, Hadoop, Excel, Mobile Apps, Web Development & many more.

You can download this VBA ScreenUpdating Excel Template here – VBA ScreenUpdating Excel Template

VBA ScreenUpdating can be noticed while we run the code or macro. While the code is running, we will be able to see how our screen is getting updated by the values generated by written code in VBA. Instead of seeing the older waiting sign, by the help of VBA ScreenUpdating we can see how the screen is updating the values of output by VBA ScreenUpdating. Now by that, we can also see the name of the article itself defines it work, VBA ScreenUpdating.

VBA ScreenUpdating – Example #1

In this example, we will see a simple code for updating the screen. For this, we need some cells with numbers, as shown below. For this, follow the below steps:

Step 1: Open a Module from the Insert menu tab as shown below.

Step 2: Now write the subprocedure in the name of VBA ScreenUpdating as shown below.

Sub

Screen_Update1()

End Sub

Step 3: We will now copy the numbers from cell A1: A3 to any other cells. Let’s say that cell be C1: C3 with the help of the below code.

Code:

Sub

Screen_Update1() Range("A1").Copy Range("C1") Range("A2").Copy Range("C2") Range("A3").Copy Range("C3")

End Sub

Step 4: Now if we run this code, we could only get the output which is copied values from column A to C. Now we will use ScreenUpdating application as shown below.

Code:

Sub

Screen_Update1() Application.ScreenUpdating Range("A1").Copy Range("C1") Range("A2").Copy Range("C2") Range("A3").Copy Range("C3")

End Sub

Step 5: We put an equal sign to select the Boolean values which are TRUE or FALSE. We will select FALSE to stop the screenupdating.

Code:

Sub

Screen_Update1() Application.ScreenUpdating =

False

Range("A1").Copy Range("C1") Range("A2").Copy Range("C2") Range("A3").Copy Range("C3")

End Sub

This could be seen more clearly if we have a huge set of numbers.

VBA ScreenUpdating – Example #2

Let’s see another example for ScreenUpdating. This time let’s consider the number from 1 to 20 from cell A1 to A20 as shown below.

For using screenupdating application, follow the below steps:

Step 1: Write the subprocedure of VBA Screenupdating as shown below.

Code:

Sub

Screen_Update2()

End Sub

Step 2: Now write the code to select the range cell from A1 to A20 and copy them at B1 to F20 as shown below. In a similar fashion as we saw in example-1.

Code:

Sub

Screen_Update2() Range("A1:A20").Copy Range("B1:F20")

End Sub

Step 3: To apply the screenupdating application, we will again use a similar line of code which we have seen in example-1.

Sub

Screen_Update2() Application.ScreenUpdating =

False

Range("A1:A20").Copy Range("B1:F20")

End Sub

The above-used application ScreenUpdating as FALSE will allow us to see how the VBA code updates the screen. As we have more numbers so there are chances we can see screenupdating.

VBA ScreenUpdating – Example #3

There is another way to see the screen getting updated. This could be done with the help of the For-Next Loop. In this example, we will print the numbers in a Row and Column combo matrix. For this, follow the below steps:

Step 1: Write the subprocedure of VBA ScreenUpdating.

Code:

Sub

Screen_Updating3()

End Sub

Step 2: Now declare the 2 variables for Row and Columns separately as data type Long.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

End Sub

Step 3: Now declare another variable which we will use as a reference to start the numbers.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

End Sub

Step 4: Now give the reference number from which position we want to start the counting. Here we are giving it as 0.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

MyNumber = 0

End Sub

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

MyNumber = 0

For

RowCount = 1

End Sub

Step 6: To continue the loop give MyNumber variable +1.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

MyNumber = 0

For

RowCount = 1

For

ColumnCount = 1

50 MyNumber = MyNumber + 1

End Sub

Step 7: Now select the Row and Column variables in Cell function. And then select the values stored in them and assign them to MyNumber variable.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

MyNumber = 0

For

RowCount = 1

For

ColumnCount = 1

50 MyNumber = MyNumber + 1 Cells(RowCount, ColumnCount).Select Cells(RowCount, ColumnCount).Value = MyNumber

End Sub

Step 8: Now close the Loop by Next. Include Row and Column variables which we defined and used in the For-Next loop.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

MyNumber = 0

For

RowCount = 1

For

ColumnCount = 1

50 MyNumber = MyNumber + 1 Cells(RowCount, ColumnCount).Select Cells(RowCount, ColumnCount).Value = MyNumber

ColumnCount

RowCount

End Sub

Step 9: Now we haven’t inserted the Screenupdating application yet. Now insert the Screenupdating application as FALSE before the start of the loop and as TRUE at the end of the loop as shown below.

Code:

Sub

Screen_Updating3()

Dim

RowCount

As Long

Dim

ColumnCount

As Long

Dim

MyNumber

As Long

Application.ScreenUpdating =

False

MyNumber = 0

For

RowCount = 1

For

ColumnCount = 1

50 MyNumber = MyNumber + 1 Cells(RowCount, ColumnCount).Select Cells(RowCount, ColumnCount).Value = MyNumber

ColumnCount

RowCount Application.ScreenUpdating =

True

End Sub

Now compile the complete code step by step by pressing the F8 function key and then run it if no error is found. We will see, how each cell of selected rows and columns is getting updated with the values stored in it.

Pros of Excel VBA ScreenUpdating

It is quite helpful in seeing how the screen is getting updated with the value stored in the loop.

We can use Screenupdating if we want to switch between worksheets and workbooks.

We can use any range of numbers.

Things to Remember

We use the insert For-Next loop as the frame or first, we can satisfy the condition of For loop and then close it by Next.

VBA ScreenUpdating is quite useful and visible if we are using a huge set of numbers.

Once done, do save the excel file as Macro enables excel format.

VBA ScreenUpdating can also be used for creating a macro through which we can send emails.

How To Fix System Service Exception Stop Code In Windows 10

While uncommon, Blue Screen of Death (BSOD) errors do still occur in Windows 10. Unlike the wall of blue text that older Windows versions displayed when a system crashed, newer Windows BSODs are simpler and easier to troubleshoot. One common BSOD error that still occurs is a System Service Exception in Windows 10.

For most users that statement means nothing. Understanding what a BSOD System Service Exception error is should help you to troubleshoot and fix the problem. If you’re facing this kind of BSOD error on your Windows PC, here are some steps to help you understand, troubleshoot, and resolve the issue.

Table of Contents

What Is A System Service Exception Error In Windows 10?

In Windows 10, a BSOD caused by a System Service Exception error (usually shown as SYSTEM_SERVICE_EXCEPTION) is unusually tricky to resolve. Unlike a Windows Stop Code Memory Management BSOD, this error has any number of potential causes.

Don’t be too surprised if this BSOD sounds familiar—this BSOD has existed in Windows for decades. While it sounds generic, the Microsoft technical explanation states that this BSOD is usually caused when a running process on your PC attempts to move from “non-privileged to privileged code.”

Windows, like all operating systems, has security levels in place for different system processes to ensure only the right code can run at the right times and by the right processes. When that fails for any reason, errors like this occur to stop the process from causing harm to your system. Unfortunately, there could be any number of causes behind this.

Update Windows 10 and Installed System Drivers

The best fixes are sometimes the simplest, and for many users, a quick trip to the Windows Settings menu to update your PC could be all you need to fix the System Service Exception Error.

Microsoft regularly issues important fixes and improvements for Windows, especially for new hardware. This includes new driver updates for your different system components.

You may need to search online for additional driver updates, however. Graphics card manufacturers like NVIDIA, for instance, often have newer drivers available on their website than those offered through Windows Update.

Run the Windows Driver Verifier Tool

Protected system code can usually only be accessed by certain system processes or devices, which is why hardware drivers usually cause System Service Exception errors in Windows 10, as they’re among the pools of third-party apps that can do this.

Even new device drivers can cause this BSOD error, especially if you’ve installed brand new hardware. If you’re unsure whether your drivers are causing this BSOD to occur, you can run the Windows Driver Verifier tool to check.

This is a troubleshooting tool that is designed to stress test your system drivers. However, be warned—this is designed to find and recreate the very bugs that cause a Stop Code System Service Exception error in the first place, so don’t run this tool while you’re using your PC for anything critical.

It is essential that you backup your PC before you do this by first creating a new system restore point. The Driver Verifier is a development tool and is designed to cause BSODs when a driver can’t be verified or if a driver is corrupted. This could mean your PC becomes stuck in a BSOD loop caused by Driver Verifier itself.

This is an entirely normal and expected result when Driver Verifier detects an issue with your drivers. You’ll need to analyze your BSOD dump files next to identify the drivers causing your BSOD issues and replace them, then disable Driver Verifier in Safe Mode (or use your System Restore point) to fix the BSOD loop it causes.

To test all the drivers on your PC, select the Automatically select all drivers installed on this computer option and then press Finish. If you want to test a specific driver, choose Select driver names from a list instead, then press Next.

If you chose the Select driver names from a list option, select the driver (or drivers) you wish to test at the next stage, then press Finish.

To stop Driver Verifier from running its driver stress test, type verifier /reset at the PowerShell window and hit enter, then restart your PC.

Resolving a Driver Verifier BSOD Loop

As we’ve mentioned, the Driver Verifier may cause additional BSOD errors when it detects an issue, forcing you into a BSOD loop. This is to be expected, and you’ll need to check your BSOD dump logs for more information. In most cases, however, upgrading or replacing your drivers will resolve the problem.

However, you’ll need to boot into Safe Mode first, then switch Driver Verifier off and delete its settings to stop this BSOD loop occurring.

After your PC restarts, select 4 or F4 to boot into Safe Mode, or 5 or F5 to boot into Safe Mode with networking features enabled.

In the new PowerShell window, type verifier to open the Driver Verifier tool.

Select Delete existing settings in the Driver Verifier Manager window, then select Finish. If your PC doesn’t automatically restart, restart it yourself at this point.

This should resolve any additional BSOD loops caused by the Driver Verifier. However, don’t forget that if Driver Verifier does cause a BSOD loop, it’s working as intended.

You’ll need to investigate your BSOD dump files for further information to identify the problematic driver (or drivers) causing your BSOD errors and update or remove them.

Restoring Your PC using System Restore

If disabling Driver Verifier in Safe Mode doesn’t resolve your BSOD loop, use the System Restore point you created before you started this process to reset your PC back to an earlier point. Otherwise, you’ll need to consider resetting Windows to factory settings as a last resort.

Select an Administrator account on your PC from the list provided and sign in accordingly. Once you’ve done this, select Next to begin the System Restore process.

Select the system restore point you created before you ran the Driver Verifier tool from the list provided, then select Next to continue.

Once you’re ready to restore your PC using this System Restore point, select Finish.

If the BSOD Verifier causes further BSODs, then you can assume that it has identified a driver that isn’t fit for purpose that could cause both BSODs. Check your BSOD dump logs for further information—once you’ve identified the rogue drivers, you’ll need to uninstall them or replace them with newer (or older) drivers.

This should help you to troubleshoot the cause of your driver BSOD issues, especially if you see a System Service Exception BSOD appear on your PC.

Run CHKDSK and SFC Tools

A problem with your drive or system files could cause a System Service Exception in Windows 10. You can run the chkdsk and sfc commands from an elevated command line or Windows PowerShell window to double-check if this is the case.

To check the integrity of your Windows files, type sfc /scannow from the PowerShell window. As with the chkdsk tool, this tool will automatically detect any missing system files and correct them, where possible.

Reset or Reinstall Windows 10

When all else fails, and if you’ve ruled out a problem with your hardware itself, then resetting Windows 10 to its default state (or wiping and reinstalling it entirely) may remove any conflicts causing this BSOD error.

Note: Once this process begins, there’s no turning back, so make sure you’ve backed up your PC first.

Keep Windows 10 Updated to Prevent BSOD Errors

The steps we’ve listed above should help you troubleshoot the problem when a Stop Code System Service Exception BSOD appears on your PC. In many cases, keeping your system updated should stop BSODs from appearing, unless there’s a more serious hardware issue at fault.
