#### newbie question on multi-dimensional array

```Hi all,

I have a real lame question about multi-dimensional array operation.
Suppose I have defined a two-dimensional array "Array(10,10)". If I
want to use the Excel function "Average" to compute the average value
of Column, say 10, of that 2D array, is there any way to realize it? I
tried "Application.Average(Array(:,10))", but apparently the Excel
doesn't like that. (You can see I am a Matlab guy, so please don't
laugh at me:) )
Any comments are extremely welcome.

Sub ArrayTest()
Dim i As Long
Dim j As Long
Dim arrNums() As Double
Dim arrCol As Variant

'11 columns
ReDim arrNums(0 To 10, 0 To 10)
'Fill the array
For i = 0 To 10
For j = 10 To 0 Step -1

'If you set row_num or column_num to 0 (zero), then

MsgBox Application.Average(arrCol)

Printing multi copies
I want to print 2 pages per sheet of paper. I have selected Multiple pages per sheet. I indicate that pages I want and preview if find for one copy. If I then indicate that I want 10 copies of the Multiple Pages, then the preview reverts to two pages of the same page. It just duplicates one page twice and I lost the second (different) page I want. This is a printer issue. I've tried to duplicate this, but I cannot with my printer. Might try converting to PDF and then printing. There are free converters around. www.primopdf.com is mentioned here often. -- Mary Sauer http://msau...

Mailbox move question
All, I initiated the movement of several large mailboxes 1 gig plus last night. It did not complete by this morning, so I canceled the move. They canceled just fine, and people have access to their email, but the server is SLOW. It isn't a processor thing either, it is strictly IO from what I can tell. Anyone have similar experience?

Question about CEdit and ENTER-TAB keys
I've a CEdit control inside a CDialog, and I want to perform a checkup in the value of the CEdit, but ONLY when the user hits ENTER or TAB. I guess that the TAB can be done using the ON_EN_KILLFOCUS(IDC_EDIT1, OnKillfocusEdit1) map. However, I have not been able to find an event for the Enter case. ON_EN_CHANGE(IDC_EDIT1,OnChangeEdit1) doesn't work for me, since I'd like to perform the check ONLY after an Enter, not anytime the text in the control changes. I also tried overriding OnKeyDown in the CEdit class, but the message is not triggered for Enter key. So, my question is: Is...

Re: What is an efficient way to determine if a value is in an array?
Right now I have a list of 300 items, and I want to see if they belon to one of three sets of values. I keep the 300 items in column A o page 1, and on pages 2, 3, and 4 I have the other three lists of value in columns A respectively. Right now I am using a VLOOKUP on each of the three sheets, and if i exists I return the value in the adjacent column, which is always "1". I run this vlookup for each page, and put the return value in th three adjacent columns next to my original value. This works, but the problem is that it returns the dreaded #N/A if i doesnt exist in the page. ...

extremely basic question about paragraph indenting
This is a terribly basic question but I can't find the answer in Word Help. How do I indent all the paragraphs of a Word document, not just one para... Michael Well, if you want *all* the paragraphs indented, then maybe you actually want to change the margins? So, for instance, that there is a 2-inch left margin on every page instead of a 1-in margin? To do that, go to Format | Document | Margins (assuming you are using MacWord). (This will partially affect the headers). Otherwise, you can indent more than one paragraph at a time by selecting more than one paragraph at a time, and th...

Question about x.y.z order
My god, I have some excel file, the data sheets have so many columns, and I need order like following, 1.1.1 1.1.1.2 1.1.2.1 1.1.3 1.1.4.2.3 1.2.5 1.10.6 1.11.1 How ever, using the excel order function, it looks like 1.1.1 1.1.1.2 1.1.2.1 1.1.3 1.1.4.2.3 1.10.6 1.11.1 1.2.5 The 1.2.5 shell before 1.10.6, how can I do it? Thanks for help. If you entered the values as: 001.001.001.002 (as many leading 0's as you need for the biggest number) Then your sort would work fine. An alternative is to insert as many empty columns to the right and then using data|text to columns|delimited by ...

Double-Click question
I have a function that is called by both WM_LBUTTONDOWN and WM_LBUTTONDBLCLK messages. However the double-click behavior seems to depend on the state of the system (what exactly I don't know). Can anyone speculate what might cause this? Could it be the time limit between clicks or could the state of the system reduce this time limit? (BTW, what is the limit normally set at?) Thanks, E-Jo Define "state of the system". The double-click behavior is independent of any other consideration of system state unless your code is dependent on the system state. The only thing that th...

Multi page worksheet question
Hi guys i have a roster that is on a single worksheet. What i want to do is when I change a name into a particular shift it then takes that shift and copies the shift onto another worksheet. So when its done each employee will have a worksheet with just his shifts on it, there are only 5 employee's atm, so instead of them having to go through every day to see what each day has they can just click on their own name and get a roster that has the week setup for them. Does this make sense? if not I can post the roster to show you what it is I want to accomplish. many thanks -- Codger ...
