Slow Down Loop At Each Loop

Nov 18, 2006

Going through a loop, I am trying to load pictures into an image box (or alternatively into a label) one by one i.e. going through the loop the first time, I want to load picture 1, then on the second loop, picture 2 and so on. A bit like an automated slide show.

I have written a simple loop and have used the loadpicture function to load the picture into the image box. When the code runs, the image box only gets populated after the last run through the loop. I have tried using application.screen updating function and the image.activate function without success. It is a simple bit of code and I expect an easy problem to solve if you know excel vba well.

Slow For Loop With IF Statment

Nov 23, 2009

why the code below is very slow with the extra if statment in it (marked with **) i have googled around and found that my for staments are correct i have tried screen updating etc. i have added a timer to see what diffrence it makes, what i have is 3 sheets 1st has about 100 rows with a number and time same as second but that only has 2 rows of the same the 3rd sheet has about 100 rows of just a number what the code does is loop through the 3rd sheet (build list) when it finds a number it looks on the first sheet to find the same number then gets the data in the second coloum and so on until it reaches a cell that says stop.

i have added a button to start this process, with the ** line in it takes 311 seconds with out it it takes 0.17 seconds

Slow Macro Loop

Jan 10, 2007

Need some alternative code that would speed the execution of this macro. My weak attempt runs noticeably SLOW.

Dim cell As Range
For Each cell In Range("TPD")
If IsNumeric(cell) And Not IsEmpty(cell) Then
If cell.Value > 0 Then
cell.EntireColumn.Hidden = False
cell.EntireColumn.Hidden = True
End If
End If
On Error Goto 0

Loop Within A Loop (repeat The Loop Values)

Mar 31, 2008

With Sheets("regrade pharm_standalone")
For Each r In .Range("standaloneTerritory")
If r.Value = "X101" Then
Sheets("X101").Range("A1").End(xlDown).Offset(1).PasteSpecial xlPasteValues
End If
Next r
End With
I need to repeat this loop for values from X101 to X151. In all cases, the sheet name is equal to the value I'm looking up (eg: value = X102 goes to sheet X102).

I have a named range called 'territories' that contains the list of X101 -> X152.

I'm hoping to make the code perform the loop for each of the territories without my having to copy & paste and change the 'X101' 51 times as this would seem a rather silly thing to do!

Loop Through Multiple Files And Call Macros (but Unable To Loop)

May 14, 2014

Macro which loops through a number of files and calls the same macro in each of them. Unfortunately when I add "Application.Run..." to the code, it no longer loops through the process and instead stops after updating the first file in the loop. If I remove the "Application.Run..." code and add any other code, the loop works fine and it continues through the process repeating all the steps for each file found.

Why it stops after one file when using "Application.Run..." to call the macros?

NB I have a list of path and file names starting in row 8 of columns A and C. Each file in the list has a macro called UpdateS1 and promoupdate1.

Sub C_Run_Loop_Macro()
Dim lastRow As Long
Dim i As Long

Store Row Number Within Loop And Delete All Stored Rows After Loop?

Sep 11, 2013

I have working code that returns a row number within a for loop based on parameters I set.

Each time the for loop runs I would like to store this row number, then after the loop has finished, delete all stored rows.

for rowNum = 1 to x (some variable end row number which I already have worked out using End(xlUp).Row)
if x = y then
*storedRow = rowNum
end if
next rowNum

Lines with a * are the bits I can't work out. I've been trying to understand arrays by reading posts on what other people have done, but I can't fit (or fully understand) the reDims, or reDim preserves into my code. I've seen what appear to be quite complex ways involving uBounds and LBounds, but unfortunately I can't see how to use them.

All I want is to simply keep adding a row numbers to a variable, (i.e. row 2, 5, 20, 33, 120, etc) and then delete those specific rows.

Loop Through Cells And Ranges Reverse Order With Backwards Loop

Aug 30, 2006

I am looping through each cell in a range and I would like to loop in reverse order.

Dim CELL As range
Dim TotalRows As Long
TotalRows = Cells(Rows.Count, 1).End(xlUp).Row
For Each CELL In Range("C1", "C" & TotalRows)
'Code here to delete a row based on criteria

I have tried:

For Each CELL In Range("C" & TotalRows, "C1")

and it does not make a difference. I need to loop in reverse order since what I am doing in the loop is deleting a row. I am looking at a cell and determining its value. If the value is so much, then the row gets deleted. The problem is that the next row "moves up" one row (taking the pervious cell's address) and therefore the For Each Next loop thinks it has already looked at that row.

Loop Through Index Worksheets Using For Loop And Select Clause

Nov 4, 2013

I have a workbook that contains, say, 50 worksheets: the first two worksheets summarise the data and are static in that they don't move position. However, the next four worksheets contain certain data for any given month. Each time a new month comes along, say, November, I insert four new worksheets after the two static ones as a result October's four worksheets are simply moved down the line in terms of worksheet order.

I need a macro to refer to the first six worksheets only (not the other tabs). I opted for index referencing for each worksheet, ie one - six. Now within these six worksheets in any given month, I need to sort the data by a certain column. The problem: in sheets 1,4,5 and 6 I need to rank by column E, but in sheets 2 and 3 I need to rank by column C. I have stepped through the code, which works for sheets 3-6, but doesn't seem to refer to sheets 1-2.

Sub WorksheetLoop()
' Loop through an indexed number of worksheets; _
' & this ensures that the worksheet range is dynamic _
' and is able to adjust when new sheets are added/removed, etc.
'Dim ws As Worksheet
Dim i As Long
Dim ws As Worksheet

Avoid Changing A Loop Counter Within A Loop?

Oct 24, 2009

I've worked on a solution for this thread ( but have been mentally challenged with how to avoid changing the loop counter in one of the loops I have used to resort an array of file names from the getopenfile dialog.

The aim of the shown code (see post 12 of the above link for attached file) is to check if the file containing the macro is included in the array returned by getopenfile while sorting the array of file names, and if so, moving it to the end of the array for "deletion" by redimming the array to exclude the last item. This problem of the open file being selected in the dialog may never arise, but... as the OP's request in the other thread was to allow two-way comparisons between numerous files, I've considered it likely enough to test for.

Here's the code I have settled for esp between the commented lines of hash symbols, which does change the counter (see the commented exclamation marks), but prevents an infinite loop (on my second try!) by using a second boolean flag of "HasCounterBeenChanged". Is there a better way of doing this? Or, alternatively (not in my thread title), is it possible to prevent the active file being selected through one of the arguments in the getopenfilename method?

Copying From One Loop To Paste Into Another Loop?

Aug 27, 2012

I am working on some code that loops through a column of number values. Whenever it encounters a number value and a blank cell in an offset column, it places that number value into an offset cell (forming a separate column to be compared to another column in a separate sheet). I would like to take all the values in that new column and begin placing them in a new column in a separate sheet adjacent to another table. Most of the time, these values should match the adjacent values in the separate worksheet. However, if they don't match, I would like a new row to be created for that mismatched value.

For example. This is the first worksheet. So far, my macro loops through the column with rows 1-5. It looks in the offset cell(0,2) for Isempty value and then places that value into the offset cell(0,6)

Nested Loop. Inner Loop Not Running

Nov 30, 2006

i have a problem with a nested loop:

it seems like the first instance of the code is running the way i want it to run, but when it starts with the second instance, it does the first search and copy, but it seems like the nested loop is being ignored.

am i doing something wrong?

Thanks to Aaron Blood for the find_range function. i also poached the lastrow function from somewhere on ozgrid, but I cant remember the name of the poster.

For b = 1 To i
If Cells(1 + b, 3).Value = "P" Then
Cells(1 + b, 29).Value = 1
If Cells(1 + b, 3).Value = "S" Then
Cells(1 + b, 29).Value = 2

Endless Loop Within A Loop

Oct 28, 2006

I have loops working in other loops. The macro is almsot working well. It does the calculation i want but it fails to stop a loop, because of that, the macro can't run the next main loop (c), which is to move to the next cell where the calculations must be run.

I attach a file. the troubleshooting macroation is Sub Itiration.

The code of this macro are bellow. Basically, the loop using d as counter run into an endless loop. I don't how to stop this loop without affecting the results which are calculated correctly.

Sub Itiration()
Dim CurCell As Object
Dim TempSum As Double
Dim d As Integer

For c = 3 To Cells(3, 4)
If Cells(11, c) > 0 Then
For i = 1 To Cells(10, c)

Loop Gets Slower On Each Loop

Jul 20, 2007

I am parsing 15,000 files from a network server. The files are all the same format and length. The problem is that the first few iterations of my loop run fairly quickly, 7 to 9 seconds a case, but after only 300 iterations I'm up to 60 seconds a case. How do I keep the last iteration running as fast as the first iteration? I've included the main loop of my parsing routine below.

Sub Fill_Summary_Tabs() 'fills out the Datapack and JMP tabs
Application. ScreenUpdating = False 'turn off screen updating for speed

Call PrepImporterTab 'formats the Importer Tab so that everything runs smoothly < 1 second
Dim fs
Set fs = CreateObject("Scripting.FileSystemObject") 'part of the filename test

For N = StartingCase To EndingCase '***** Start of the Parsing Loop *****

Loop Or For Each Within A For Each

Jan 22, 2010

I am having some technical difficulties trying to place data onto sheet2. Sheet2 starts out blank, as sheet1 is proccessed it pastes data to sheet2. I have tried a "For Each" that failed only pasting data into Range "A1" for every found instance.

In the code below, the area colored "Magenta", I need a Loop of some type that as data is pasted into column A on sheet2, it indexes to the next available cell and continues. How do I construct such a Loop or For Each with in the existing For Each?

For Each Loop

Sep 7, 2007

I don't get For Each loops. All I want to do is cycle through everywork sheet in the active workbook and lock certain cells. I've got the lock part working right but I have no idea how to effectively preform this on each sheet. From what I've read I think a For Each loop is the best way, but I can figure out how it works.

For Each Next Loop

Jan 19, 2010

This is my first time using the "For Each Next" loop. I want to subtotal values in each sheet. Unless I make the worksheet active in the loop the code kept summing the same worksheet.

The question is do I have to activate the next sheet in the loop. Here is the code I have been using:

Sub SumCost()
Dim WS As Worksheet
Dim FinalRow As Integer
For Each WS In ActiveWorkbook.Worksheets
FinalRow = Cells(Rows.Count, 11).End(xlUp).Row
Range("k" & FinalRow + 1).Formula = "=sum(k2:k" & FinalRow & ")"
Range("A" & FinalRow + 1).Value = "Total"
Next WS
End Sub

Do Until... Loop

May 2, 2006

I don't know what I am doing wrong, but I know this should be verrrrry simple, and for some reason I just can't get it to work. I have the following

Sub HighlightRawData()
Do Until Selection = "x"
If Selection < 0 Then
With Selection.Interior
.ColorIndex = 6
.Pattern = xlSolid
End With
Else: Selection. Offset(1, 0).Select
Exit Do
Selection.Offset(1, 0).Select

End Sub

This code is supposed to look at each cell in column A, and if it is not blank, it is supposed to highlight the entire row yellow and move down one row. If the cell is blank, I want it to just move down to the next row. The loop is supposed to run until it hits the "x" at the end of the range of cells.
