excel cannot complete this task with available resources

Hi folks,

I encountered a memory problem when I ran my codes. Basically I used the codes to compare two similar entries in two excel files and then saved each comparison result in a new excel file.

The problem is that when the entry number increases to 7000 and above, a error message pops out saying: excel cannot complete this task with available resources. I checked the memory of the computer. There is still half of the memory unused.

I think it may reach the limit of memory usage for excel 2007 (2Gb). Do you guys have any idea how to release memory using VBA codes? Or any other idea how to solve the problem?

By the way I don't think it is the problem with copying and pasting since I didn't use many. I suspect that it is because I created too many workbooks (over 7000).

My system info:
Excel 2007 & Windows XP Home Edition SP2
Intel Core 2 Quad CPU Q6600 @ 2.4GHz
3.23GB of RAM

Here is the code:

[vba]
Dim AK_14 As Workbook, AK_15 As Workbook
Dim Pre_candi As String, Char_candi As String, FileName As String, pre_Candii As String
Dim i As Long, j As Long, row_n14 As Long, row_n15 As Long, col_n14 As Integer, col_n15 As Integer, row_res As Long, rows_n15 As Long
Dim m As Integer, n As Integer, Com_Ions As Integer, Com_YBs As Integer, Cols_N14 As Integer, Cols_N15 As Integer

It may be that the Undo stack is filling up as the macro runs. You can clear it after each Add-Close operation, by adding a "do-nothing" line of code:

Sub ClearUndo()
Range("A1").Copy Range("A1")
End Sub
This clears out the stack. Hope this helps.

It still builds up to the limit after processing 7000 files. Any other ideas?

Reading your code, I realized that you never clear the stack after copying, which may be causing a problem. After each Paste or PasteSpecial is complete, add the code:

Application.CutCopyMode = False

this may help.

Sorry I didnt solve the problem. I found out that it was the problem with too many workbooks adding and closing. Do you have any idea how to solve that problem?

I don't have any more ideas about the memory issue. If it were my project, I would save each set of results as XML. In fact, you can set up results once, and save the file as XML to get the framework. Then, use that as a template to write out each text file.
