Excel: Progress Bar Indicator with VBA There was a request for an Excel Progress bar with percentage

indicator. While I personally don’t understand the need for

something like that, I am happy to oblige.

Lets say we have this fictitious scenario. We have a spreadsheet with

65536 numbers in it. I want to go through each number, and in the

cell next to it, put an ‘X’ if the number is a prime number. There will

be a small form that pops up with a progress bar and percentage

indicator while the macro is processing. I am purposely using a

inefficient function for determining Prime Numbers so we can have a

noticeable delay in the processing in order to demonstrate the

Progress Bar indicator.

To start, create a new Excel worksheet. In Cell A1, put in the value of

1. Select all of Column A, go up to “Edit”, “Fill”, and select “Series”.

This will fill out all of column a with the numbers 1 – 65536.

I will now create the progress bar itself on a user form. First, I go

into the Excel Macro Editor, choose this workbook, go to the “Insert”

menu at the top of the screen, and select UserForm. When the

component toolbox opens up, I right mouse click on it and

choose “Additional Controls”. (Alternatively, I could go up to

the “Tools”/”Additional Controls” menu) From the list of

components, I select “Microsoft Progress Bar Control 6.0 (SP4)”. I

then draw a form with the progress bar and 1 text label, as illustrated

below. One thing to be sure of is to set the UserForm1 property

of “ShowModal” to false; otherwise the progress bar will display and

sit without processing anything else in the script.

And below is the code for the Workbook.

'ignore the values of 1, 2, and 3 and answer appropriately

If (n = 1) Then Exit Function

isPrime = True

Exit Function

End If

'If number is divisible by 2 or 3, it is not prime

Hi. My name is Bill, and I wanted to thank you for this great tip. I

have created a workbook with a macro that takes several seconds and

I am fearful that once I release it for general use, fimpatient folks will

start hitting keys. With a visible progress meter, I won't be so

concerned.

Thanks for the tip!!

Thank you for this loading bar. I find it extremely usefull, since my

wait, and if they do wait, they need to see the progress...:)

So, how would i tweak this to track the progress of multiple

subroutines. For example, if I have 1 workbook that contains 10

subroutine. Each subroutine calls a separate workbook and performs

a series of code on that workbook, and then closed the workbook and

calls the next subroutine.

I'd want the % progress indicator to be based on the # of subroutines

I'm the same poster as above. Maybe better yet, to possibily make it

easier, tweak it based on counting the # of lines of code in all of the

subroutines instead of the # of subroutines

John Ward said...

That is a little tricky to do. If this were .Net, you could use the

StackTrace package. Since thats not an option, there are a few

options.

For 1, if you have 10 subs, then after each execution you would be

roughly 10 percent complete and could update the progress bar

accordingly.

If you wanted to, you could also go old school Basic and put in the

line numbers in your code. Then, you can figure out how far along in

your code execution you are through a little math. Luckily there are

programs out there that will add the line numbers automatically.

So would you be able to show me a working example using the

subroutines below? How specifically would the VBA look?

Sub Macro2()

Range("B1").Select

Anonymous,

Something like this would work... I wrote a small function to

demonstrate this, it takes 1 over the number of functions in the total

program and multiplies that by the current function number, which

will give you the percent complete. Then it updates the progrss bar

based on that.

I also included the Sleep function since I needed to slow down the

execution to see this work. Note I included the progressbar update

before I make the call to MacroX due to the recursive nature of the

function calls:

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As

Long)

Private Sub CommandButton1_Click()

Macro1

End Sub

Sub updateProgressBar(totalSubs As Integer, subNumber As

Integer, ByRef progressBarToUpdate As ProgressBar)

Dim percentComplete As Integer

'Get the percentage of sub routines complete based on the currently

Página Web 6 de 13


executing subroutine

percentComplete = ((1 / totalSubs) * subNumber)

'Update the progressbar with the percent complete

progressBarToUpdate.Value = (100 * percentComplete)

Sleep (3000)

End Sub

Sub Macro1()

Range("A1").Select

ActiveCell.FormulaR1C1 = "a"

updateProgressBar 5, 1, ProgressBar1

Macro2

End Sub

Sub Macro2()

Range("B1").Select

ActiveCell.FormulaR1C1 = "b"


Macro3

End Sub

Sub Macro3()

Range("C1").Select

ActiveCell.FormulaR1C1 = "c"


Macro4

End Sub

Sub Macro4()

Range("D1").Select

ActiveCell.FormulaR1C1 = "d"


Macro5

End Sub

Sub Macro5()

Range("E1").Select

ActiveCell.FormulaR1C1 = "e"

ProgressBar1.Value = (100 / 5) * 1


End Sub

I got that to work in your example, but I can't seems to get it to work

in my customer made sheet now. Here's the code I'm using:

Página Web 7 de 13



Integer, ByRef progressBarToUpdate As ProgressBar)






progressBarToUpdate.Value = (100 * percentComplete)

End Sub

Sub start_freq()

UserForm1.Show

ActiveWorkbook.RefreshAll

ActiveWorkbook.Save

Workbooks.Add

ActiveWorkbook.SaveAs Filename:= _

"C:\Documents and Settings\book2.xls" _

, FileFormat:=xlNormal, Password:="", WriteResPassword:="", _

ReadOnlyRecommended:=False, CreateBackup:=False

Windows("book2.xls").Activate

Sheets("Tab Definitions").Select

updateProgressBar 5, 1, ProgressBar

(I have more after this, but I cut it off here at where the error occurs)

I get the following error at the last line above:

Compile error:

ByRef argument type mismatch

I can't see the mismatch, but maybe I am just going blind.

updateProgressBar 5, 1, ProgressBar

In that statement, the use of ProgressBar should be disallowed since

ProgressBar is a type. You need to pass in the name of the

Pogressbar Variable as it is named on your form, such as

Página Web 8 de 13


pbOverallProgress, or pbProgress.

3:44 PM

Still the same error:

The Progress Bar is named pbBar in the Form (UserForm1 is it's

name)


Integer, ByRef progressBartoUpdate As ProgressBar)


Dim pbBar As ProgressBar





progressBartoUpdate.Value = (100 * percentComplete)

End Sub

Sub start_freq()

'UserForm1.Show

ActiveWorkbook.RefreshAll

ActiveWorkbook.Save

Workbooks.Add

ActiveWorkbook.SaveAs Filename:= _

"C:\Documents and Settings\book2.xls" _

, FileFormat:=xlNormal, Password:="", WriteResPassword:="", _

ReadOnlyRecommended:=False, CreateBackup:=False

Windows("book2.xls").Activate

Sheets("Tab Definitions").Select

updateProgressBar 5, 1, pbBar

7:14 AM

John Ward said...

Whoops.... my bad, I overlooked something there. In the function

updateProgressBar, percentComplete will always get assigned the

Página Web 9 de 13


value of 0 since ((1 / totalSubs) * subNumber) will always return a

real number. Integer casts will automatically cut off the remaining

decimals. So to fix your function you would need to update

percentComplete to read like so:



Dim percentComplete As Single





progressBartoUpdate.Value = percentComplete * 100

End Sub

I wasn't paying attention to that when I posted it originally. Make

sure you are using your code in the same module as UserForm1.

Drop the statement dim pbBar as progressBar in updateProgressBar

since it is not necessary. I changed start_freq in the below example

since I don't have the books2.xls file you are referencing, but it

should go something like this:

Option Explicit

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As

Long)

Const LOOP_MAX As Integer = 10



Dim percentComplete As Single





progressBartoUpdate.Value = percentComplete * 100

End Sub

Sub start_freq()

Dim x As Integer

For x = 1 To LOOP_MAX

Página Web 10 de 13


updateProgressBar LOOP_MAX, x, pbBar

Sleep (900)

DoEvents

Next

End Sub

Private Sub CommandButton1_Click()

start_freq

End Sub

Awesome!!! Everything works perfect now.

While we're at it ( :-) ) , do you happen to know if there is a way,

while a series of Subroutines are running one right after the other, to

Stop the Macro running these Subroutines and then Start them back

up - both by the click of a button.

I answered that question in a seperate post:

Man you are just absolutely awesome. Got my processes working

99% flawlessly now.

The only 1% I am left to figure out is how to keep my progress bar

active the entire time all of the other subroutine/macros are running.

If I click off of the workbook that contains the subroutines and

userform, and then try to click back on it to activate it while the other

subroutines are running then I can't see the progress (one of those

excel things).

So I was wondering if there was a way to have excel call up MSAccess

and have the Userform/Progress Bar in MSAccess and be able to

have it talk back and forth with Excel as Excel is running the

subroutines/macros so that the MSAccess Progress Bar (which I



have in Excel currently) can update.

Possible?

Hi John,

I am trying to use progressbar code in my application. I have read all

comments in this blog and followed every step but still get an error

message "Comile Error: User-defined type not defined" and I think

my VBA is accepting "progressbar" as user-defined type.

Prasad,

Possibly, change ProgressBar to something like myProgressBar. Int

he version I used int eh above example (Excell 2000), it wasnt as

picky. That may not be the case for you. If you want, post your code

and I will take a look.

Hi,

I have a similar question. I have a worksheet, where I hide/show

params in a pivot table, which in turn re-calculates the whole

worksheet, which takes about 3-4 minutes. How do I show the

progress bar during that recalc time? Thanks.

ShowModal = "False", brilliant, that statement was apparently too
