Excel Vba Clear Memory Cache
How do I clear the memory between procedures/calls to prevent an "out of memory" issue occurring? Thanks excel vba memory share|improve this question asked Jan 18 '13 at 10:32 Marc L 2783820 1 Its likely that you need to look at the structure of your VBA, and particularly any very large arrays/strings it might be working with - break these down into batches to limit the total usage of memory by your code at any one out of memory excel time. –Jon Egerton Jan 18 '13 at 10:34 Release Variant, Object whenever possible (Erase, Set object = nothing) . ReDim them to a more reasonable size, loop them in buffer size. But most probably reason is the spreadsheet too large (check in task manager if it's taking >500M RAM before running any macro) . You may want to open a read-only spreadsheet, remove all unused Sheets ( This will free a lot of memory) –Larry Jan 18 '13 at 10:37 You should show the code which is causing the problem. –Tim Williams Jan 18 '13 at 15:54 You could use 64bit office to get round the issue temporarily but you still need to address the problem like mentioned my most people. –Dreamwalker Jan 24 '13 at 14:20 2 You might not even be having memory issues - I've encountered VBA reporting "Out of Memory" errors, when the root cause was a function in an add-on DLL I had written raising an exception, thinking VBA would report that to the user. Apparently "Out of Memory" can also be VBA's way of saying "I don't know WTF to do about this"! –Loophole Jul 21 '14 at 3:00 add a comment| 4 Answers 4 active oldest votes up vote 8 down vote The best way to help memory to be freed is to nullify large objects: Su

Currently, the saved spreadsheet is about 76MB, and pretty much all of it gets read into arrays in memory for various manipulations. At times, I get Visual Basic "out of memory" error messages, and when I use the Application.MemoryUsed and Application.MemoryAvailable functions, I show about 1,000,000 bytes available and about 84,000,000 bytes used. At the same time, out of memory though, when I use Ctrl-Alt-Delete to look at my SYSTEM memory, I have lots free... Excel is using about 500 MB, and I have over that much physical memory showing as available (I have 2GB ram on the computer). So I'm thinking that there's a limit in Excel that I'm really close to, 84,000,000 used and 1,000,000 available, and I start to write this post to see if there's a way to allocate more of my physical memory so that Excel can use it, since I'm not done doing all the things I want to do with this data. HOWEVER, when I try to generate the exact "out of memory" error by loading an older (but still large) version of the spreadsheet, to my surprise I do NOT get an out of memory error, but instead my "in use" memory in Excel shows 155,000,000+ bytes, and the "available" memory shows THE SAME 1,048,576 bytes available. Huh. Am I IN FACT close to any limits for memory, or will Excel actually use whatever the system has available and I'll only get errors when I have other programs in use hogging resources? Is Application.MemoryAvailable a bogus indicator? Should I be worried? Thanks! G.T.

Is Application.MemoryAvailable a valid indicator of what's really available to Excel, or no? Thanks! Reply With
Visual Basic Editor usg990a10-19-2006, 04:41 PMI am having a problem where I am unable to open the Visual Basic Editor in Excel. Each time I attempt to open it (using Alt+F11 or Tools>Macro>Visual Basic Editor) I get a message box with the out of memory error. I have built several addins (.xla) for Excel in the past. I attempted to unload them from Excel (via Add-ins menu) and even went as far as deleting the files thinking that perhaps my previous code did not destroy all objects. After doing a complete shutdown and restart, I still get the same message when Excel is the only application open. I have searched the forums and can find several references to the out of memory error but in context of during run-time of a procedure or with an Access database, but never when simply trying to open the editor. Any suggestions on this would be greatly appreciated. Mike Rosenblum10-20-2006, 11:52 AMUnfortunately, I think that you likely have some sort of corruption. You might need to uninstall/re-install or roll-back to a restore point (if you have a restore point that you can use). I think the first check here would be to start up Excel in 'Safe Mode'. Here's a couple of articles on it: Startup Errors In Excel (CPearson) (http://www.cpearson.com/excel/StartupErrors.htm) How to troubleshoot startup problems in Excel (MSKB) (http://support.microsoft.com/kb/280504) Oddly, neither article mentions the easiest way to start up Excel in Safe Mode: you simlpy hold hown the CTRL key when opening up Excel. You must HOLD it down while Excel is loading until you get a confirm box. (You cannot simply hit it briefly while clicking on the mouse, for it will take a second or two for the code to get to the point in the loading process where it checks for the CTRL key to effect Safe Mode.) When you get the confirm box, hit the 'Yes' button. Running under Safe Mode runs with full functionality, but no addins are loaded, the XLStart directory is ignored, Personal.xls is not loaded and your cutomized toolbars held within your *.XLB file are also not loaded. You can still run macros, etc, but the loading process is 100% clean. (This really should be called "Safe Boot" not "Safe Mode" because, as far as I know, there is no functionality actually prevented once it's loaded, as far as I know
