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)
Do

Why does my Excel hang on this
While TempWaarde1 <> ""
TempWaarde1 = Cells.Value(Posi, 1)
TempWaarde2 = Cells.Value(Posi - 1, 1)
If TempWaarde1 <> TempWaarde2 Then
ListBox1.AddItem TempWaarde1
End If
Posi = Posi + 1
Wend
What I'm trying to achief is to fill a listbox with all values in the first column of the active sheet, but avoiding double entry's if they're on the row after the 1st one. When I execute this in my Userform_Initialize, Excel hangs like the while-wend loop is never finishing, while i'm sure there is no more data in the 1st column after 200 rows or so.

I've used a loop in one of my macros and the loop goes on endlessly. I've been trying to come up witha way to overcome this problem but with no luck till now. knowing that I'm new to VBA i decided to turn to the big guns at mr.exxcel to help me out. Here's the code i have. Any alternatives to this would be VERY VERY VERY USEFUL!!!
Sub smalloops()
Dim i As Integer
Dim compliant As Integer
Dim noncompliant As Integer
compliant = 0
noncompliant = 0
For i = 1 To 60
Do Until Cells(i, 2) = ("RECOMMENDATIONS")
Do While Cells(i, 3) 0
If Cells(i, 7) = 1 Then
compliant = compliant + 1
ElseIf Cells(i, 7) = 2 Then.................

I have the following VBA in the attatched spreadsheet (seperated so I could upload)
The only problem that I have is that I cannot stop the loop, it constantly keeps going round in a circle.
What im wanting to do is when the Date checked is the End date and the End Time has been checked, to move onto the next row and do it again until it gets to row 40.
Sub Calculate()
Dim CellNo As Integer
Dim CurrentDate As Date
Dim StartDate As Date
Dim EndDate As Date
Dim theDate As String
Dim c As Range
Dim i As Integer
Dim addDate As Integer
Dim DaysHoursSick As Date
Dim StartWorkTime As Date
Dim EndWorkTime As Date
Dim endmarker As String
I've only got this VBA working really under Wednesday so I can make sure it is right before adding it onto the other dates,

Having another problem with the same macro that has been giving me trouble for a week now. Now, the macro will run, but after it finishes, excel stops responding. Is this because the macro continues to run indefinitely.

I have a multi-sheet workbook. The first sheet is a summary of results from the rest of the workbook. I would like this summary sheet to auto-refresh itself each time the sheet is activated. The VBA code triggered by the Worksheet/Activate event feeds some parameters out to other sheets, then copies back the results to the summary sheet of the workbook.
While doing so, it keeps "reactivating" the first sheet, causing it to get into an endless loop that is triggered by the Worksheet/Activate event. Essentially, I'd like the Worksheet/Activate event to go dormant for 15 seconds or so each time it is triggered.

I have a very long routine, looping through 35,000-ish rows several times to detect and delete unwanted items. Occasionally, it gets locked into an endless loop and CTRL+Break will not stop it - I have to kill Excel through the Task Manager.
How can I find out where the endless loop is so I can detect what's causingit and fix it?

When I set a "for each cell in range" to go through the range, and if there are merged cells in this range, this will result an endless loop.

With Sheets("regrade pharm_standalone")
For Each r In .Range("standaloneTerritory")
If r.Value = "X101" Then
r.EntireRow.Copy
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!

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.

Dim i As Long

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.
Code:
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.

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)
CELL.Select
'Code here to delete a row based on criteria
Next
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.

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 i As Long

I've worked on a solution for this thread (http://www.excelforum.com/excel-prog...-automate.html) 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?

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)

For Each loop can be instructed to loop starting the bottom of the range. I know that a For To Loop can handle looping from the bottom up,
Sub Filterout()
Dim c As Range
Dim rng As Range
Dim i As Long
Dim lrow As Long
Dim counter As Integer
lrow = Cells(Rows.Count, 3).End(xlUp).Row
Set rng = Range("c2:c36")
For Each c In rng
If Left(c.Value, 1) "~~" Then
c.EntireRow.Delete
End If
Next c

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?

I have got a loop which is working fine but now i need another loop which will run till the end but need to repeat itself as soon the column x become 1 the highest number would be 3
here is my main loop A1 = 5000
and second loop need to run inside the this loop
Sheet1.Activate
i = Range("A1")
For b = 1 To i
If Cells(1 + b, 3).Value = "P" Then
Cells(1 + b, 29).Value = 1
Else
If Cells(1 + b, 3).Value = "S" Then
Cells(1 + b, 29).Value = 2
Else
If Cells(1 + b, 3).Value = "C" Then
Cells(1 + b, 29).Value = 3
End If
End If
End If

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.

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 *****
Sheets("Setup"). Cells(20 + N, 1).Value = Time 'Print the start time of each case....................

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?

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.

I have a spreadsheet that uses columns A:I. I want excel to be able to look at a row in the spreadsheet and where column I is empty it should delete cells I and H, then look at cell G and if it is empty, delete cells G and F, and then do exactly the same for columns E and C.
also, this spreadsheet is not always the same length, but always starts at row 15
