Ensure Automatic Calculation
Apr 30, 2008
I have largish workbooks (10MB) with a variety of formulas and lookups to generate tables and charts. Calculation is ALWAYS set to Automatic, but sometimes (not always) the formulas fail to update when values are changed. Sometimes F9 will force calculation, sometimes Ctrl + Alt + F9, sometimes (especially with charts) I have to close the workbook and reopen before they will update. The workbooks contain macros but none are running when this happens. A search of your forum indicated that this question has arisen several times before, but I haven't seen a definitive answer.

In attached file, I need to find a way for "y" to be automatically calculated. But for that, "y" needs to first find out which equation to use, depending upon the corresponding entry in first column.
would somebody know how to do it ?
I was trying vlookup, but couldn't.

When i have automatic calculation on, excel freezes. When i push the escape key i get focus back to excel but then it nearly immediatley loses focus again. I have to keep hitting excel to navigate anywhere with excel. By turning calculations to manual it no longer freezes. Is there a way to identify whats causing this freeze, I went through and deleted nearly all events? Why would auto calculate freeze excel if no changes are being made to a formula?

Is there a way of using VBA to check which calculation option is on - "automatic" or "manual" ?

I am working in a fairly large worksheet, and I realized that when I make changes to it, sometimes some of the cells do no recalculate. The only way I can get them to recalculate is by clicking into the cell, and then hitting return.
The issue is that I don't know which ones are failing to recalculate unless I click into each individual cell and hit return to see if it changes. This would be logistically impossible given the size of my sheet.
Has this ever happened to anyone else? Does anyone have any suggestions as to how to fix this issue?

I have several data validation style drop down menus, and I basically don't want excel to recognize changes in these cells and execute a calculation of the entire workbook. Since there is a large number of calculations being performed in the workbook the sheet gets really slow.
Overall the way excel "automatically calculates" really screws me up a lot. This built in functionality could be a lot smarter in my opinion.

I need to average data following the format below by average per week by week/store combination e.g. wk 1/store A average is 6.
Week
Store
Sales
1
A
7
[Code] ..
I can easily use SUMIFS to achieve this, but I have a large amount of data between the weeks of 1-52, a dozen different stores and I will be adding to this. I don't want to have to enter new SUMIFS every time I enter a new wk/store combination. How do I get this info to automatically calculate?

I have this problem where the SUM function is returning 0. The context is this- I am simulating values using RAND() and looking up the values corersponding to probabilities from a different tables. I then use the TRIM function to return the value I need, and the final number is of a "general" format.
This is the formula in the column I wish to sum:
And this is dragged down the column.
When I change the cells using =VALUE(cell) the SUM function then returns the required value. Oddly the SUMPRODUCT function seems to work.
Calculation is set to automatic and the cell has been formatted as a number.

I know how to turn off automatic and manual calculation modes manually in excel or through VB. But is there a way to make the automatic calculation mode ignore changes in certian cells? It would be good if you could right click on a cell and turn this on/off as an option. I assume I will have to code this in vb somehow, but I am a novice. Something like:
Sub test123()
For Cells = Value.Range("I7:R22")
Application.Calculation = xlCalculationManual
Like I basically want part of my sheet to be set to manual calculation mode, and partially to automatic...

I have a table with rows that keep growing. But I have place formula in the whole of column F, i.e. F2:F66565. When I import information from MS Access into column A to E, the formula in F does not work, until I copy from F2 to the end manually. I have tried using Tools, Options, Calculation, Automatic. That doesn't work, I have also tried F9, that doesn't work and I have also tried checking Precision as Displayed under the calculation tax in Tools-Options, that doesn't work either.

I have workbooks in which summary tables are generated by lookup formulas. Tables are on different sheets but all use the same lookup value by referring to a cell on the 'master' sheet. The lookup value appears in cells on all sheets, by reference to the master sheet (e.g. [formula] = mastersheet!$B$2).
The master sheet contains the main summary table and is copied and detached for distribution, using a macro. For practical reasons, this is done in two stages, first copying the sheet within the workbook (to make minor alterations), then moving it to a new book to save and distribute.
This is where the problem arises. After the sheet has been detached, we find that if we now change the lookup value on the master sheet in the original file, the tables on that sheet will update normally, but the cells on other sheets remain frozen at the previous value and the tables on those sheets do not update.
The only way round the problem is by Shift + Ctrl + Alt + F9. (Maybe I should add that all my workbooks are always set to automatic calculation.)
The macro itself is not the cause of the problem; if we follow the same procedure manually, the result is the same. However, if we move the sheet in one step, eliminating the intermediate copying stage, the problem does not arise. But this is evading the problem, not solving it, and I would be reluctant to have to resort to this.
The original problem remains as stated, viz. failure of automatic calculation.

which will calculate value of a cell when one of the variables has been changed?
To illustrate what I have in mind, an ecxample:
* User can add values to cells using UserForm
- Component name (to Cell "A1")
- Component price (to Cell "B1")
- Component quantity (to Cell "C1")
[Code]....

My form has a combobox with three options "Withdrawal" "Deposit" "Fee". I want to make sure that whatever number a user puts into a textbox, if they select "Withdrawal" or "Fee" that number will be converted to a negative number, and if they select "Deposit" it will be positive. I have written the following code and am just wondering if there is some super slick way of doing it other than an if statement.

I enter for example in a cell : 0625-C0/01
sometime 0 is entered as O a letter and not zero.Is there a way to ensure that only 0 (zero) is allowed in that string using data validation rules.

I have five text boxes on a user form. I would like the 5th box to always equal 100 - the Sum of the other boxes, and never go below 0.
In other words, the text boxes are representing percentage breakdowns - so to validate the percentage entry in each box i want the last box to 'count down' from 100 as the percentages are distributed amoungst the other boxes. This box will also be a percentage figure, so is crucial it has its own box (rather than just saying these four boxes have to total 100) i hope this makes sense!
I have tried a code along these lines (see below) - (adapted from this forum but couldnt get it to work) I also found a version where one poster used a command to change the 'value' from string to numbers - but have been unable to find that again.
Private Sub txtbox1.change()
txtbox5 = 100 - (CCur(txtbox1) + CCur(txtbox2) + CCur(txtbox3) + CCur(txtbox4))
End Sub

I have two enormous lists of dates. How do I automatically compare them to ensure the date on one comes after the date on the other one?
They're formatted as dates. Christmas Day 2000 (UK) did say 25/12/2000, and then when I reformatted it it automatically changed to 25 Dec 2000, and so on.

I'm looking for a way to ensure that users of a spreadsheet have filled in all required cells. VBA code which will prompt if a cell is blank which will activate on a button click
All cells are 'Named ranges' so hoping there's a way in which I can point to all named ranges and if they're blank display the below error message.
"Please ensure you have filled in all required fields"

I have a workbook containing several sheets, each sheet has a large number of ActiveX check box controls on it.
The controls are presented in groups of three to capture responses to a question (Y/N/NA). If one of the three check boxes is set to True, the other two associated check boxes must be set to False.
What I want to do is avoid having to have an On_Click event sub for every single check box.
I have written a function that will handle updating the related check boxes but I am unsure how to call this function, passing it the name of the clicked Check Box whenever any check box is clicked.
Here is my current code with an On_Click event being used to call the function:
Private Sub chk100_01Y_Click()
' Want to replace this with a dynamic sub that will be invoked
' when any Check Box is clicked and pass the name of that Check
' box to the function
Call Update(ActiveSheet.OLEObjects("chk100_01Y"))
End Sub

I have the formula but it will always change when i shift my cell down
=MAX($G$21:G35)
When I shift my cell G21 down, it will change to below

The problem is that I do not want the formula to change. How can I do it ?

I have created a survey in excel 2003. It has 70 questions on it and the user responds to the questions by clicking on a radio button. There are 4 radio buttons within a group box for each question and the user will select one of them.
At the end of 'sheet 1' with all these questions on, i have a button which the user presses to proceed to 'sheet 2'. When they press the button i want to ensure is that all questions have been answered ie: 1 of the radio buttons is selected for every question.
If one of the questions isnt answered then a pop up box will appear to tell the user they have unanswered questions and then the vba code will exit and the user stays on the question sheet (sheet 1). If all the questions are answered then the user will move to 'sheet 2'. (the reference cells for all the groups of radio buttons are within column G on sheet 1).

I have a range B1:B20. These cells are populated by the user and I want to ensure that no two entries are the same. Is there a way of presenting a dialog box that prompts the user to enter a different value if the value they are trying to enter is already entered somewhere in the range?

I have written some code that copies certain cells from a spreadsheet constructed form back to a master spreadsheet database. The idea being to prevent users of the form from accessing the database and mucking it up. I write it the long way round and am now trying to modify it to not have to open and close the database everytime BUT whenever I change it I get errors that I think relate to the code not understanding the change of object...
' 3. send updated data to the database (all yellow boxes will update)
' set parameters for cells to copy from
Dim r As Long, e4 As Long, e6 As Long, e18 As Long, e20 As Long, e22 As Long, e24 As Long, _
e26 As Long, e28 As Long, e30 As Long, e32 As Long, e34 As Long, e36 As Long, e38 As Long, _
e40 As Long, e42 As Long, e44 As Long, e46 As Long
r = Range("D2")
e4 = Range("B4")
e6 = Range("B6")
e18 = Range("B18")
e20 = Range("B20")
e22 = Range("B22")
e24 = Range("B24")
The little blocks of code go on for 17 open/closes!
