    <p><strong>The Task</strong></p> <p>I'm working on a VBA project wherein I store the data from a sheet in a <code>Variant Array</code>, do a bunch of calculations with the data in the <code>Array</code>, store the results of those computations in a few other <code>Arrays</code>, then finally I store all the "results arrays" in another <code>Variant Array</code> and write that array to a range in a new sheet. </p> <p>Note: this process has been working fine ever since I first wrote the procedure.</p> <p><strong>The Issue</strong></p> <p>After a very minor logic change, my final <code>Array</code> will no longer write to the specified range. I get <code>Run-time error '7': Out of memory</code> when I try. I changed the logic back in case that was my issue, but I still get the error. </p> <p>After doing some research, I tried to erase all the arrays (including the one containing all the sheet data) before writing to the range, but that didn't work either. I've checked Task Manager and that shows my RAM as having a lot of free space (almost 6K MBs available and over 1k Mbs "free"). (Task Manager shows the Excel process as using around 120 MBs.)</p> <p><strong>The Code (Snippet)</strong></p> <pre><code>Dim R As Range Dim ALCount As Long Dim All(5) As Variant Dim sht As Worksheet Dim Arr1() As Long Dim Arr2() As Date Dim Arr3() As Date Dim Arr4() As Long Dim Arr5() As String All(1) = Arr1 All(2) = Arr2 All(3) = Arr3 All(4) = Arr4 All(5) = Arr5 Set R = sht.Cells(2,1) R.Resize(ALCount - 1, 5).Value = Application.Transpose(All) </code></pre> <p><strong>More Details</strong></p> <pre><code>My device: Win 7 64-Bit Excel: 2010 32-Bit File Size: &lt;20 MBs Macro Location: Personal Workbook Personal WB Size: &lt; 3 MBs </code></pre> <p><strong>Edit: Array Size: 773x5</strong></p> <p>Any thoughts on why this might be happening?</p>

    1. COYou might need to show more code. You say the array size is 753x5, but the array is declared as `All(5)` - that's only a 1D array.

    2. COInteresting discussion [here](http://social.msdn.microsoft.com/Forums/en-US/c45d37f1-a5f1-4cf4-938d-69d294d8e447/limitations-on-arrays?forum=isvvba). They don't come to a conclusion but seem to think that there is a hard limit in some versions of Excel of around 2^16 array elements when writing to a range. I don't see anything overtly wrong with the code you've included. When you say "my final `Array` will no longer write to the specified range", do you mean that the code will run fine until that line?

    3. CO@TimWilliams I've added the code where I assign the other arrays to `All`. If I'm doing this wrong, how in the world was it able to work before? I haven't changed anything about the arrays since the last time it worked.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
