Reset Memory Or Clear Old Value

Jun 19, 2007

How come I keep having the same value for "lastrow". eg: 35

lastrow = ActiveSheet.UsedRange.Rows.Count

It doesn't matter how many rows of data I've changed, it still show lastrow = 35.

I tried to add an extra line above but still doesn't work:

lastrow = 0
lastrow = ActiveSheet.UsedRange.Rows.Count

Pivot Table Cache (Refresh/Clear Memory Space)

Jun 4, 2008

I am currently taking over a workbook from a colleague that contains 10 pivot tables. Spaced out over a few sheets.

Each pivot table contains a lot of information and my current workaround to refreshing them all is..

Step1:Refresh 2 Pivots,
Step2:Save and Close document,
Step3: Re-Open document and repeat Steps 1 & 2 until all refreshed.

I was wondering if there was any kind of code to clear the memory space being used by the pivots thus leaving the hard coded information behind.

That way I can just write some vb to refresh all the pivots and not keep saving and re-opening the document which takes sometime as its on a network drive.

Reset / Clear ComboBox

Jan 11, 2008

I have a userform with several combo boxes on it. I also have three command buttons, 'OK', 'Reset' and 'Cancel'. I want to code the 'Reset' command button to reset the values of the combo boxes to empty or "". I have attempted to do this simply by using the following code.

Private Sub cmdReset_Click()
cmbWaterTemp.Value = ""
cmbTypeFastIce.Value = ""
cmbIceDrift.Value = ""
cmbTrendBehavior.Value = ""
End Sub

When I click on the 'Reset' command button I get the following error.

"Run-time error '94':
Invalid use of Null"

When I use the debug tool the error pointed to is a different sub.

Private Sub cmbWaterTemp_Change()
txtTemp1Encoded.Text = Left(cmbWaterTemp.value, 1)
txtTemp2Encoded.Text = Right(cmbWaterTemp.Value, 1)
End Sub

I am not exactly sure why the error points to this sub. I know there must be a simple way to accomplish this. I am including a workbook that is similar though not exactly the same due to file constraints. What I want to happen is when the 'Reset' button is clicked is to clear all values for the combo boxes and the text boxes. I have successfully gotten the textbox values to clear although not the combo boxes.

Create A Clear/reset Button?

Sep 3, 2009

I'm just finishing a project that is a collection of three calculators, each of which returns data based on a series of user-supplied variables. All the mechanics are working [thanks in part to replies to previous posts], but there is one more thing I'd like to add:

Does anyone have a way to clear the contents of another cell [actually several] cells via another cell? As the most complex calculator requires eight variables to be entered, I'd like to provide a quick way [a button?] to "clear" or "reset" the calculator - basically wipe all unlocked cells. I should note that all of the cells in question already have Data Validation of one type or another.

Clear Contents Of Rows To Reset Used Row Count?

Jul 18, 2013

I am working on some code that I would like the user to be able to re-run should the underlying data in the adjacent tabs change. My existing code is shown below

Code:
Option Explicit
Dim wb As Workbook
Dim ws As Worksheet

[Code]....

I'd like to be able to remove all data on the ALL tab so that when the UsedRange.Rows.Count is run again on that page it will only see the header row. In the past I've deleted or cleared data from the sheet and the Rows.Count still counts the rows which have no content in them.

Clear Macro NOT Clear Formula?

Aug 15, 2014

I'm having a problem with a macro clearing a formula in a cell. I have the same type of cell that doesn't have the problem but I can't find the difference between the 2 cells or difference in vb that's making it happen. I have to intentionally cause this to happen but don't see why it's happening. Do I need to attach workbook and describe what's happening? I have been copying and pasting from different sources as well as paying to have it created/started but it was expensive(for me) and I make nothing off of it, just use it at work. I am not proficient in Excel or vb but I'm desperately trying to learn as I go so as not to fork out a few hundred dollars again.

here's atleast the vb for the macros:

VB:
Sub clearclientinfo() '
'
'
'
Sheet5.Select

[Code].....

Out Of Memory

Dec 15, 2006

I have name 28 columns. The range in EACH columns is 6:14000, i.e. the first name is date and the range is from Row B6 to Row B14000.

I am using SumProduct instead of VlookUp to look up values. An example of one of my sumproduct formulas:

SUMPRODUCT(--(Date=$B$6),--(Book=$D$6),PnL___Book)

where the first columns has dates, the next column is bookname and the last column is the profit and loss for each book, i.e. the values that need to be addad.

Now, suddenly I do not get any numbers but just #VALUE! but if I change the range to a lot less, e.g. between Row B6 and B50, it works.

My questions is if this has to do with memory in Excel. Are there limits to how many formulas and how many names you can have before Excel crashes. I am aware that the 28 columns names are very large.

Are there any way of how to get around this, VBA-codes or other formulas that uses less power, not naming columns or what?

Looking For A More Memory-efficient Way

Mar 31, 2009

I am currently using Excel 2003 to pull from 2 external spreadsheets to compile data. The first sheet (seniority list.xls) being referenced contains all of our employees (approximately 350 rows, but that can vary from 340 to 450) as well as some information (employee ID, full time or part time, etc.). The second sheet being referenced (pay.xls) contains a breakdown of all employees and their pay for a particular bi-weekly period.

What I'm looking to do is:

(1) Find out all of my current employees. I do this by referencing seniority list.xls.

(2) For each employee, find out how many hours they worked each week. I need to do this by referencing pay.xls. Unfortunately, that file works quite differently than seniority list.xls. Unlike the latter, which contains one employee number per row, pay.xls could contain as many or as few rows per employee as their schedule dictates. Each row contains things such as overtime, regular time, double time, alternate regular time, alternate OT, vacation, sick pay, etc. In total, pay.xls could contain as many as approximately 8000 rows. To determine how many hours they work, I'm using this CSE (array) formula:

(Note that the employee ID is in column A of the current sheet.)

Book Using Too Much Memory?

Dec 23, 2013

I have a large amount of data on NBA teams and players that is extracted from external web pages. In order to have the data shown on separate sheets to do comparisons I have to use many array formulas and from what I have read that takes up a large amount of memory. I'm now at the point where I'm receiving a message that says "Excel cannot complete this task with available resources" when I open the workbook.

Is there any plausible way that I can resolve this situation? I have thought about converting the lookup formulas from arrays (index/match) to vlookups and hlookups.

I'm not as advanced with using Excel as most of you, and I realize I may be at a point to where I will need to use different software to analyze my data, but I would prefer to stick with Excel as it would be difficult to start from scratch and learn how to use a different program.

ADO: Memory Leak

Oct 4, 2006

Regarding the Memory Leak problem with ADO, does anyone know of a workaround?

The workaround mentioned on Microsoft's website (http://support.microsoft.com/default...;en-us;Q319998) pertains to using ADO to retrieve a recordset from an Excel worksheet, not from an Access Database.

1) Does anyone know if those workarounds would also address retrieving a recordset from an Access Database?

2) If so, is the "SELECT INTO" workaround effective?

Is this Memory Leak issue relatively minor or only affecting Excel 2000? I'm guessing it must be one of those 2 things since the concensus is ADO is superior to MSQuery..

Memory Usage ...

Dec 6, 2006

I'm using a Dell P4, 1.6Ghz, 512Mhz of memory (Win2K & Excel 2003), and it's bogging on spreadsheets that aren't that big and complicated (compared to thing's I did years ago, in the days of 386's and Win98)...

It hits the 100% CPU usage and stays there for minutes (especially when saving) on files that are only around 2M in size, yet it's not using much of the memory...

Spreadsheets large or small seem to have little effect on how much memory is being used... is Win2K allocating a fixed % of total memory for Excel to use?... can this be changed, so Excel gets to use more of the available memory?

I've been cleaning up and redesigning my spreadsheets to make them more efficient, but there seems to be a disconnect between my hardware specs and Excel's performance with files that aren't that big ~:-/

Disabling my antivirus software (Nortons) prior to saving, seems to speed it up a little, but this is not something I should be having to do...

Flush Memory VBA

Apr 8, 2007

One of my apps I run is very large and memory intensive, and there are several subsequent procedures which tend to either bog down or errors out before the program finishes running.

Is there a way to clear the memory out?

And adding more physical memory is not an option, I have 4gigs already and Excel can only utilize 1gig anyway.

Protection Password Memory

Jan 27, 2010

I have tried Tools/Options/Security Password to modify, but it can still be saved as a copy to the network which becomes very confusing to many. If I use Tools/Potect Sheet, I need to re-enter the password for all sheets twice. I am trying have it so that everyone is read only, select people can edit (with same password). Password protect all sheets and the workbook with the same password everytime when the workbook is closed

Basically 2 questions

1) Is there a way of remembering a password so that when the workbook is closed it and all sheets are automatically protected with the same password every time

2) Is it possible to have it not copied unless it is opened by an editor

How Much Memory Do Command Buttons Add

Jan 17, 2014

I have been having an internal debate of how my worksheets shoud be configured.

My workbook could potentially contain 300+ worksheets, 10 control buttons and around 20 macros.

Each worksheet contains data in a range ~ A1:AC40 with many blank cells.

Do you think a workbook with this many worksheets would be unmanageable given the Comp Spec of the user PC below?

Most of the cells are simply short text data.

System info
Processor: 2.3Ghz Dual Processor
RAM: 2GB

SQL And VBA Memory Usage And Clean Up

Feb 3, 2010

I have created an excel tool w/ A LOT of macros in it, and the tool "speaks" to the SQL server (downloads data from it and uploads it back). My big problem now is that every time I run any of the VBA code the amount of RAM that is getting allocated to Excel (2007) is increasing - I am checking it in the Task Manager. So if I work for a long time without closing down Excel - my entire RAM is getting consumed and the system slows down, and sometimes crushes.

I was wondering if there is a way in VBA to clean up memory that is used by Excel.

Do you have any hints? I am using extensively 3 things - screenupdating off; displaymessages off, and calculations off. But this speeds up Excel but doesn't reduce the memory usage.

Excel Runs Out Of Memory

Jun 10, 2014

I have a macro which filters data on one sheet and copies that data onto 34 new sheets . This works perfectly until the 25th pass when Excel advises that there is insufficient memory to continue. I assumed that this was connected to the clipboard and its ability to remember 24 chunks of data so I turned it off but still Excel gave up at the 25th pass. Is there a way that I can clear the clipboard during the macro's execution or is there something else going on?

Out Of Memory On Loop And Match

Jun 18, 2014

I have come across one of those annoying 'out-of-memory' errors. See my code below:

Code:
'Dimensions (first rows and cols)
Const frow3 As Integer = 17
Const frow4 As Integer = 19
Const fcol3 As Integer = 10
Const fcol4 As Integer = 11

Sub Extract()
Dim ws As Worksheet, target As Worksheet, meta As Worksheet

[Code] .......

The code executes fine until it gets to End Sub. Some object eats up memory but I don't understand which one.

Sort An Array In VBA Memory

Jul 11, 2007

two parts:

1.
The following is the VBA version of what i've been using:

Range("A1:J1000").Sort Key1:=Range("D2"), Order1:=xlAscending, Key2:= _
Range("E2"), Order2:=xlAscending, Key3:=Range("F2"), Order3:=xlDescending _
, Header:=xlGuess, OrderCustom:=1, MatchCase:=False, Orientation:= _
xlTopToBottom, DataOption1:=xlSortNormal, DataOption2:=xlSortNormal, _
DataOption3:=xlSortNormal
now arrays are bigger than 1000 rows>> even bigger than 65536.

Such an array is stored in "arrBIG" and dimed as (1 to 10, 1 to 100000). The goal is to sort it by the 4'th, then 5th then 6th values in the first dimension - the one that is 1 to 10 - i call this the column.

arrBIG.Sort Key1:=4, Order1:=xlAscending, Key2:= _
5, Order2:=xlAscending, Key3:=6, Order3:=xlDescending _.................

Not Enough Memory On Data Import

Sep 9, 2008

I'm trying to import data into my sheet with formulae like this in row1(Columns A:I): ='F:Dir[File.xls]Sheet'!A2.

The files I'm importing the data from all have 50.000 rows and 9 columns, so I copy the formulae downward 50.000 times. This generates an error ('Not enough memory'), not surprisingly. I've also tried to do it in steps by way of VBA; first two thousand, copy and paste values, next two thousand etc. But that doesn't work either.

Does anyone know of a solution to this memory problem or a way to work around it (without opening the files with the data in them).

Out Of Memory - Is My User Form Too Big

Jun 3, 2009

I have recently just encountered a problem where whenever I try and run / edit any part of my user-form code i get the following error:

Compile Error:

Out of memory

The help document then lists about 12 things that could cause this.

My user form code is very small, however the form itself is large, it has a multipage with 12 tabs, each tab then contains between 50 and 100 labels which populate with data from the spreadsheet in the background.

Do you think this size could be causing the error? If not, does anyone have any solutions / ideas?

My hardware / software setup is all ok.

Reduce Picture Memory

May 1, 2006

I got a CD with pricing and (high resolution) pictures (for printing). I've built the search/display macros for displaying a page on the net, so all I want to do is reduce the pics (Adobe Photoshop) to save memory - easy, right? Why can't I get the pics out of excel for work in Photoshop? I've done the tools>options>General tab>ignore other applications (clear) thing. I've done the "shift>edit>copy picture" or "right-click>copy" thing - but I can't paste anything anywhere. What's up? I didn't think I was this bad, but I guess I am; life is humbling.

Web Page > Memory Reduction

May 5, 2006

I have windows XP and xl2k. I have a single- sheet workbook (9MB) linked to another multi-sheet workbook of databases (20MB). The single-sheet workbook has about 100 pictures (30k ea) that, when a number is entered, searches the database. If no match is found for a given picture and product info, then the picture is deleted and the rows are hidden (macros). Usually, about 10 products are found in the database for any one entry.

My goal is that I can "save as > web page" and email these results off to my customer. The problem is the after-the-search result page is about 1MB and so too is the .htm file that is created when I "save as > web page." I was thinking that 10 pictures at 30k should be around 300k plus the formatting (no?). I cleared the "tools>option>general>web options>general>save any additional hidden data..." to little effect. Is there a macro that will delete the hidden rows which I should run AFTER the product search (because deleting them instead of hiding them messes up the macro run) - I'm sure that would help (right?). But my original thought was that the .htm file size would not be affected by hidden rows.

The per-item section of excel is 375 cells + the picture with simple font and formatting and no other objects, etc... When I delete the picture and save as > web page just this one-item section area (375 cells), the .html file is 37kb in size. That seems large to me (yes/no?). (10 x 37K = 370K before pictures!). This may be a reasonable file size, I'm no expert. I read a post where xl2003 has a compression application - is that what I need, or is there a 3rd-party app that can help me reduce the size of this file in htm. Or, is this the best I can expect from this method and I should be exploring elsewhere (metatags?).

Memory Usage Limited To 1 Gig

Jun 24, 2006

I was reading in the sticky post about the new version of Excel that is due out this year. One of the improvements listed was the increase of usable memory by Excel from 1gig to the amount of Windows memory. In reading this, am I to understand that increasing a machine's physical memory above 1gig is useless for Excel in the current version? My specific issue is I have a very involved worksheet that takes about 2.5 minutes to calculate and this will increase as more data is added, it is heavy formula laden. I was going to increase memory from 2gig to 4gig to assist in reducing the calculation time.
