Reset For Loop On Each Iteration?

Jul 2, 2014

I want to iterate a For Loop changing one variable each iteration until the Total from the For Loop equals zero. Each iteration of the Do Loop keeps the previous Total from the For Loop and adds it. How do I reset the For Loop to start from Total = 0 at the beginning of the For Loop?

Sub PV_IRR()
Discount_Rate = Range("A2")
Total_Investment = Range("B2")
Annual_Return = Range("C2")

Reset Variables For Each Pass Through For Loop

Jun 27, 2014

I am having trouble defining a variable in a For loop. When I run the loop the first time everything seems to work fine, but when the loop goes back through the second time it carries its previous value with it. Here in lies the problem if the variable is supposed to be empty (not assigned a value). So, for example: 'Variable' in the code below may or may not be given a value depending on the conditions in the For i loop. If it is given a value then 'Variable' will still have that value on the next pass through the For j loop. And if none of the conditions are met for the If statement in the For i loop the second time through the For j loop, it should be an empty variable, but instead the code is reading it as having a value (from the previous pass through the For j loop).

[Code] .....

I have tried using:

[Code] .....

After the For j line, and instead of using:

[Code] ....

I tried using:

[Code] ....

and I've tried:

[Code] .....

I get an Object error with either line I use. I just want to be able to reset the variables each time through the For j loop so in the case of an empty variable, it doesn't try to calculate based on the previous value.

Good Way To Reset Variable Each Loop To Empty?

Apr 15, 2012

I'm using a variable to loop down a column of data. Each time it loops the variable may or may not perform an operation - it will if there is something in the cell but won't if the cell is empty. It writes the answer of the operation to an ajoining cell, before looping again.

The issue is that if the row cell is empty, what's written to the ajoining cell is the pre-existing value of the variable, because its value hasn't changed.

how best to 'empty' the variable each loop to ensure either that the correct value or nothing at all is written to the ajoining cell?

Iteration

Feb 10, 2009

Suddenly I have a problem with copying formulas:

I started with the following formula: =COUNTIF($D2:$D5694,D5724)
I then copied it to the next line: =COUNTIF($D3:$D5695,D5725)

That's not supposed to happen if you use the $ sign. So I checked Tools > Options > calculation. That is set to automatic. What else could cause my problem?

Utilizing Iteration In Conjunction With Function

Nov 1, 2008

I would like to start with a spending value, (SV), that would be the amount of money that I want to spend in a year, not counting taxes. The function (or functions) would then go through some sort of iterative calculation process that would compute the total spending level including taxes, (TS), the federal tax, (FT), and the state tax, (ST).

These values would have the relationship that TS=SV+FT+ST. When the iteration was finished, the federal tax and state tax amounts would be consistent with the taxes that would be due for this level of total spending as determined by the normal tax tables for both federal and state taxes.

I am not concerned that the tax figures be absolutely exact, so a lot of iteration is probably not necessary.

Code Loops Through Range Instead Of Crashing On Second Iteration

Apr 6, 2014

Not come across this issue before where the Code works once then fails to iterate!

In attached file 140405 Loop not working.xlsm, for each cell in C4:C27 on the Inventory Sheet, the Code should:

Look in the Data Input sheet.

Find the Item Number in Col B corresponding to the number in Col A of the Inventory Sheet.

Find the quantity on the Data Input sheet corresponding to that number.

Copy the quantity into Col H of the Inventory sheet.

The Code works for the first row then throws error message "Run Time error 13" Type Mismatch!

VB:
Sub OFFLOAD()
Dim Dest As Range, Dest1 As Range, oCell As Range
Set Dest = Sheet2.Range("C:C")
Set Dest1 = Sheet2.Range("B:B")

Sheets("INVENTORY").Select

Error In Code Regarding Iteration Through Multiple For Each Loops

May 23, 2014

I am having some trouble with some code I am trying to write for some calculations. I am trying to make excel iterate through a range of cells in 2 columns and compare the cells in each row of the column to a set different number. If both the numbers in the row pass the test then I add them to a count. I know it is simple but I am really struggling with my basic vba knowledge to correctly iterate through 2 columns.

A
B

5
8

8
4

2
9

9
9

For example say my "cutoffs" are a value greater than 2 for numbers in column A and a value greater than 5 for numbers in column B. The program then should return me a value of 2 for this example.

Option Explicit
Function cutoff(phi_cutoff As Double, sw_cutoff As Long, gross As Double)

Dim count As Double
Dim my_range1 As Range
Dim my_range2 As Range
Dim c1 As Range
Dim c2 As Range
Dim value1 As Double

[Code] ............

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
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!

Iteration Inconsistency: Allow For A Cost Being Added To Loan Amount Where The Cost Is Based On The Total Loan Amount

Mar 15, 2007

In a financial environment we have a calculator which uses iteration to allow for a cost being added to loan amount where the cost is based on the total loan amount. Iteration is set to 100 iterations with max change .001

On one PC the first time the calculator is opened it gives a particular (incorrect) result. If the input cells are cleared and the data re-entered, it gives the correct result. This only happens on one particular PC. Is there some other setting , other than the iteration setting, that would cause this?

Reset To Zero

Jun 5, 2006

I have a workbook with 20 worksheets the first is a summary called Discount Set the 19 sheets with various names

The 19 sheets in column H4:H40 u enter a number greater than 0 which is the quanty required. This is used to calculate a price on which ever row it is entered

the selection must only affect numbers as there are rows that are just shading and they contain no data .

So u could enter quanties on serval rows of different sheets to get a total price displayed in the Discount set

What I want to do is have button on the Discount Set which will clear any quantity that does not equal 0 back to 0 in column H which will reset the total 0.00

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.

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.

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)
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.

Reset Value Of Long?

Jun 2, 2009

I know that a variable of string type is equal to "" before it's assigned a value. So I reset the value of strings to empty (i.e. "") when I want them clear of a value. I also know that variables of Variant Type are equal to NULL when they are unassigned so I reset them to NULL when I want to clear them of a value.

But what about a Long? When you declare a variable of Long Type or Int Type or Double Type, what is it's inital value when empty and unassigned. I assume it's not 0 since 0 is an actual number.

I want to reset my lng variable and clear it of a value. So I'm wondering what should I set to... How can i do this?

If I click the "End" button, the window closes and Excel is at rest - which seems to be some sort of Reset process.

I have a need to execute that process while Excel is at rest.

Reset Cell Value To Zero

May 28, 2009

i have cells A1 to A10 filled with numbers
i have cells B1 to B10 blank
what i need to do is when something is typed in cell B1 - A1 to A5 are reset to zero and when i type something in cell B2 - A2 to A6 reset to zero.

I have tried to do this as a range ie

A1- A10 have numbers in B1 - B10 copy these numbers and reset if anything is typed in C1 with this formula =IF(C1:C5="",A1,"0") what it should do is reset B1 to zero if anything is typed in C1-C5 but only when something is typed in C1 does this work ..

Reset Counter

Jun 20, 2006

I am not experienced at all with Excel, here is my problem: In column "A": I have 288 rows and has nothing but numbers in them. Row 1 is the lowest number, row 288 is the highest number. In each row the numbers typically increase; every once in a while the numbers may stay the same, but the number will never be lower. The numbers range from 0 through 600,000.

What I want to do is have column "B" follow column "A" until the cell total reaches 12000. The next cell in column "B" would then reset and start all over from "0". I want it to keep on reseting every 12000 counts. Another potential problem is that a majority of the time the cell value will not be an even 12000, 24000, 36000 etc. They may be more like A40: 11742 A41: 13201 etc.

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

I have attempted to delete all of the extra rows by holding SHIFT and CTRL, striking the down arrow then right-clicking on the left margin of highlighted row numbers and choosing delete. I have also done the same procedure except clicking clear all from the editing menu. None of these methods has removed the rows and enlarged the vertical scroll bar to a proportionate size in relation to the number of rows.

Reset ALL Sorting In A File?

How do I reset ALL the sorting in a file?

The first worksheet is all formula generated and has filters at the top, which I've variously sorted alphabetical. The second worksheet is raw data the user isn't intended to read.

Now I want to alter one of the formulas. The problem is, if I change it in row 2 and fill down I get all kinds of different information. This is because while the present formulas read

='other worksheet'!A265
='other worksheet'!A934

- and so on at random, when I resort them I just get A2, A3, and so on.
