From limited experience I know that excel calculates dates via serial numbers.
I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)
I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.
What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?
Hopefully a simpler question for your experience level than mine.

Lookup number 1 from column A, then give me the largest number from column B
example table:

Posted this on the Ozgrid forums, but haven't gotten any help yet, so I thought I'd try here too!
I've been having a strange problem lately. I have a fairly lengthy macro that works perfectly most of the time. Occasionally it will run as expected but as soon as the macro ends, excel becomes unresponsive to mouse-clicks. When I click anywhere (trying to select a cell, or an excel menu item...clicking anywhere in excel) I'll get the a 'ding' system sound and nothing will happen. BUT, if I use the keyboard arrow keys, I can see that the active cell selection moves accordingly. Then it gets really strange - when I have a cell highlighted and press any key to input text, it gets duplicated. So if I press 's' it will input 'ss' into the cell, and then when I press enter it will auto-move to the next cell down, but nothing ends up getting saved into the previous cell.
I don't understand what's going on at all. I can't think of anything in my macro that would have these kinds of effects. I've made sure that screenupdating is turned back on at the end of every procedure. If I go into the VBE, I can manually run procedures and they all work fine. The only way I've been able to get back to normal is by force closing excel altogether and re-opening. Any ideas?
______________________
Still having trouble, and the same thing is happening with this workbook on two different computers, so I don't think it's a hardware, or OS specific issue. When it gets locked up like this, I can still do anything in the VBE (edits cells, run macros, etc.) with no problems. If I'm in the excel window, I can click alt on the keyboard and the shortcut keys for the menu come up, but I can't go deeper than that by clicking the letter shortcuts, they do nothing. If I use the delete key to delete the contents of a cell, then it gets deleted. But if I type anything else (numbers, letters, or symbols) then it types 2 instances of the key every time, yet when I hit enter, nothing changes in the cell. I also can't really bring focus to the excel window if something else (ie. the VBE) is on top of it, clicking into the excel window just gives the little system 'ding' sound and nothing happens.
If I hit the save button in the VBE (since I can't click anything in the excel window), then it seems to snap out of it and go back to normal. I tried searching for anything simmilar to this and can't find anything...
Any help would be much appreciated. This is driving me nuts!

Hi everyone....this is my first post here ....and not my last I believe!
My question I believe is easily solvable for you cracks of excel.
I have a worksheet with a list of rows (item#, date, price, etc). In the last column of this list I can put an x for some of the items.
On another worksheet or sheet, I need to autoamtically have a list of the items in the first list above, that have an X in the last columns.
I created an example on a worksheet attached just for you to understand.
I apreciate all the help I can get.
Thank you so much.

Hello ,
Here is my issue:
I have a list of SKUs in Excel and I need to add one same word to 500 cells that have pre-existing text in the cells. See example below:
1) List of SKU's in cells:
34
35
39
55
2) text that needs to be added IN FRONT of every number:
DF
So the result would be:
DF34
DF35
DF39
etc.
How do I do that in a formula and not manually? I found another similar thread and I understand how to do it from the instructions there but the same text goes on the back and the result is: 34DF but I need it to be like: DF34.
I am using Office 2007 for mac.
Thank you for the help,
Chris

Hi there,
I'm very new to Excel, and I'm having trouble figuring a few things out. Hopefully this will be very easy for you guys!
In Sheet 1, I have a column of cells that I would like to also appear in Sheet 2. If I add a new row to the column in Sheet 1, I would also like it to be updated automatically in Sheet 2. Currently, I can get it to show the contents of individual cells from Sheet 1 in Sheet 2 by using this formula in the formula bar for each cell in Sheet 2:
=Sheet1!A3 (or whichever cell it is)
That's fine, but I'd like to just have a formula that will reproduce the entire column (ie. without a fixed range, as new rows are going to be added to the column).
If anyone could point me in the right direction, I'd be very very grateful. Thanks.

Thought I'd append my experience of the above problem - you can find all sorts of references to it everywhere.
My problem was that a userform defined with Excel at work (containing DT pickers) gave the message in the title when opening it at home. I had a light-bulb moment and wondered whether there was a difference in the version numbers for MSCOMCT2.OCX at work and at home. Turned out the work version was newer. I then copied the MSCOMCT2.* files from work, made a backup of them at home and copied those from work to my C-drive (Windows XP - c:windowssystem32 ).
No luck. I then rebooted the machine - still no luck.
Then, finally I unregistered the old DLL via
Code:
(not sure if this was necessary, but I didn't think it could hurt). Reregistered the DLL via
Code:
and what do you know - it worked.
Summa summarum - it could be an idea to check whether the two machines have different version numbers for the MSCOMCT2.OCX files.

First time in this forum. Hi all. I have a challenging question, is there a way either by VBA or manually (preferably both, if possible) to actually unite the X amount of numbers that are in a cell given the contents is alphanumeric? I'll give you the following examples to see if you can understand what I' referring to?
DATA output should be
asd67,h876 --------> 67876
2,3,ujdj5&34 -------> 23534
909k86m34 --------> 9098634
Hope this makes sense?

I am having trouble with a sort. I would like a list sorted descending, so that the highest dollar amount is at the top. However, if there are blanks or zeros in the list, it is putting those first. How do I get it to ignore them or put them at the bottom?
Thank you,
Liz

Hi all,
I've been getting this error on occasion recently.
- It's a shared document
- There is usually 10-12 people using the file at the same time
I've read on the Microsoft Help site that the issue is that somebody is accessing the file while another is trying to open it.
Is there a way, perhaps through VBA, that I can not allow a user to save while somebody else is opening the document? Other suggestions on how to avoid this error?
Thanks!

Hi
I'm not sure how to do this, but I want the Total (column D) to be the sum of the Unit Price (column C) times the Quantity (column A). Is there a formula you can apply to a column or do I have to do it in individaul cells?

Hello,
I have a number of different files that I often need to run a macro on. In order for me to do it on the 75-100 files I have at any given time, I need to open one, run the macro, close and save, then open the next one.
Is it possible to write a macro that will start with the first file in a folder, open it and update links, run a macro, save and close, and open the next file in the folder until it has open all the files in the folder.
I have experience with creating macros that reference different workbooks, but not sure how to go about opening files with different filenames (without referencing the exact filename).
I'd like to be able to have basic code for opening, saving and closing, opening next file, saving and closing, etc. and input the macro I'd need to run in each file in the appropriate location. Is this possible? Any help is greatly appreciated!!
Thanks,
Jason

I have an image or picture within a worksheet.
I want to be able to reference it from a cell so that depending on a
validation list a different picture is shown.
Is this possible in Microsoft Exec 2000

Hello All, I have a column where cells need to be 50 characters long, it contains addresses, however, since all the addresses do not meat the criteria, I need to add (blank spaces) to reach the 50 characters, any idea on how to approach this?
Example
Fire Street #50 this cell contains 17 characters therefore I need to add the rest by adding blank spaces to reach 50 characters, otherwise the system I am exporting the data will not understand this cell

I have a couple of worksheets that have goal seek already performed on 20 target cells (for each worksheet). I did this manually, without a macro (since I'm absolutely horrible at all of this).
Now from what I can tell, I need a code to add to the worksheet module in order to make sure that the goal seek updates itself whenever I change a value in the formula of the target cell.
what IS that code?! I can't understand the codes some people have put up, so I have no idea what to do.
Target Cell: M21:M42
Changing Cells: N21: N42

I have a co-worker's file that he is having trouble with. He is using Excel 2000 SP3. When copying a cell with a formula in it of '=D6+C6' and pasting it into the next cell down, it will display the same value in the cell as the calculated value from above, but has the correct formula displayed in the formula bar of '=D7+C7'.
Example:
A1: 50
A2: 10
B1: 60
B2: 20
A3: Formula: =A1+A2 Displays: 60
Right click A3, Copy, right click B3, paste
A3 displays 60
When I click save, it will change the display value to 80.
I am trying this on his workstation and mine. Mine has Office 2010, so I think there might be an issue with the file itself.
Also, not just copy and paste. I can also just click the top cell after filling in the formula and then drag the bottom right of the cell downward and it will do the same of filling in the correct formula, but have the incorrect value.
I know that I could get him to just click save each time before really looking at the results, but that is just a band aid to the problem.
Any ideas how to fix this?
