Chris wrote about a problem he is having with VBA. It seems that he's getting the error message "out of memory" when attempting to access the VBA editor. He's tried closing all other applications, checked for background programs, and he has ample disk space. The error message even occurs in workbooks with relatively small procedures.
It could, realistically, be any number of conditions causing the problem. Because of this, it can be hard to track down the cause. There are a couple of clues that suggest that the problem may be due to either an add-in or to a problem with your macro modules.
You can figure out if it is an add-in by simply starting Excel with all the add-ins disabled. Add them back in, one at a time, until you notice the error again cropping up. You will then have a pretty good idea that the problem is caused by the last add-in you enabled.
If the problem is not due to your add-ins, then you should suspect your macro modules. If you spend a lot of time editing your modules, they can become corrupted over time. (This has been a known problem for some time in VBA.) You can usually get around this problem by recreating the workbook in which the problem occurs. Copy the worksheets from the old to the new workbook, and then use the VBA export and import capabilities to move the macro modules from the old workbook to the new one.

I don't know if Dee had problems just with the VBA Editor and the out of memory issue, or with only opening the file. Even without macros in the workbook I have to constantly remind co-workers not to format the entire worksheet, as it makes the file huge. If there are multiple worksheets in the workbook the file size can get out of control quickly when entire worksheets are formatted.

Dee, try starting Excel in safe mode (eg, hold down the Ctrl key), and see if that eliminates the message.

I don't have any active add-ins and I have never added a macro. Why would I be getting this message? My computer shows that I have plenty of memory. I closed all my running applications and restarted my computer, starting only the tiny excel file I'm using and I still get the message.

Good ideas except when moving your macros it's easier to paste them into a new module (easily created in the new workbook) if you keep them in a Word doc or text file. If you email this to yourself your macro collection will always be safe for reuse.
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
