I have 50 share returns for 2009 (A2:A51). I am solving for optimal portfolio by allocating weights to my 50 shares in 2009. in solver, i am changing cells B2:B51, but the criteria is that if any of the 2009 returns is greater than 75 then the weight on that share should be 0. i tried to write an if function in column C of the changing cells but solver overrides the command when i solve.

Under Solver, the changing cells box only alllow 200 adjustable cells. I had problem that my adjustable cells is more than 200. Is there anyway I can increase it ? maybe using VB.
View 2 Replies View RelatedI'm trying to use solver to find the minimum value of a cell by changing 5 separate cells. These cells are subject to a set of constraints that are formulae. On top of that I have a large number of these solve's to run (The spreadsheet is creating randomly distributed data to form a Monte Carlo simulation). Therefore I am referencing the formulas using the ActiveCell, Offset() function. For some reason when running this code none of the values are changed. Also I changed the UserFinish to false so I could see what solver was doing at each solve, It stops at the correct cell (one after the final cell) but without me having to confirm it each time.

I want to restrict a textbox to only let the user fill negative values. So first of all he/she shouldn't be able to fill in a text, and only values. And if a value is filled in, then it should be a negative value (automatically).

A macro is assigned to then extract this data and paste into the recording sheets behind.
I would like to format somehow cells B11:B15 so that only numeric entries can be pasted in and not any alpha including #.

I want to use solver program. But when solver "changes cells" i want it to trigger my pivot tables in the workbook. So i added the code to my worksheet:

So when a change occurs, all my pivot tables will get refreshed and my data will change. Is solver able to trigger this event while solving an optimization problem?
I have a Macro 'Timenow' to give current time in a Cell of MS Excel, but then it changes all Cell values of sheet where the macro was used.
Sub Timenow()
'
' Timenow Macro
' Keyboard Shortcut: Ctrl+b
ActiveCell.FormulaR1C1 = "=NOW()"
Selection.NumberFormat = "h:mm"
Range("F5").Select
End Sub
Even assigning value to variable does not work:
Sub Timenow()
' Timenow Macro
' Keyboard Shortcut: Ctrl+b
Dim TN As String
TN = Format("=now()", "h:mm")
ActiveCell.Value = TN
End Sub
how to restrict the macro to change the value of current/active cell only without effecting other cell values?
I have a cell, D5, which is the sum of three other cells, A5 B5 and C5. (all currently empty). Cells A1 through C4 are filled with various numbers.
What I've been trying to do is use solver to say: Make D5 equal 200, do it by manipulating only A5 B5 and C5, and make it subject to the constraint that A5 must equal a value selected from A1:A4, and B5 must equal a value from B1:B4, and C5 ...etc. I have deliberately set it up so that there is only one solution.
I was doing fine until trying to create the constraints. How can I make a constraint that says "this cell" must equal "one of the following cells"? And if I can't do that, is there an alternate method of achieving the same result?
I am trying to multiply a range of cells by a cell reference. The cells currently have hard coded values in them. I know with past special you can multiply a range of cells by a copied #. I want a similar function to that just instead of a copied cell its a cell reference. No VBA.
View 5 Replies View RelatedThis may have been answered on here but can not seem to find it. My situation is I have values in A1,A2 & A3 that are like counter reading so the value is always changing. What I am looking to do is change the cell color if one of the values is over 500 from the other two values. Say A1 is 3000, A2 is 3250 and A3 is 3500. I would like the cell for A3 to change color.

View 6 Replies View RelatedI have taken over a workbook that due to various constraints elsewhere I cannot change the structure.
Each of the three columns in question C, E & F have dropdown validation lists.
Column C is either Import or Export
Column E is a list of locations where work is Imported From

Based on whatever choice is made in column C either Import or Export I only want the user to be able to select a value in E or F.
So if Import is selected then a value cannot be entered in F

View 3 Replies View RelatedI am trying to get a macro that converts Japanese digits to their Roman counterparts but does it only in a specific column. My original version just selected the J column and then Cells.Replace ran just fine on just that column. I have discovered, however, that the users may make the crucial column either J or K, so I changed it to search for the header first, and then select that column. It replaces in the entire sheet, however.
Here's what I've got (I've only given you one digit replacement. The What doesn't display properly because this forum doesn't display Japanese):
I have a cell in a spreadsheet which has a lot of text entered. The spreadsheet needs to be used by another application (Business Objects).
My problem is that I need to limit the number of characters entered in the cell to 255 characters. I know I can use Data, Validation to limit the text length, but this only works once all the data has been entered, then a message is displayed.
My ideal soulution would be:
When a user is entering text and has reached my 255 character limit, no more text can be entered;
or
When a user is entering text and has reached my 255 character limit, the text automatically continues in the next cell.
A not so elegant solution (but a usable) would be:
A character counter to let the users know when 255 characters have been reached.
This may be a two part question, I finally was able to build a calender contol to insert dates into a active cell, now what i am trying to do is be able to restrict the usage of certain dates. For instance, dates prior to the current date cannot be chosen, nor dates that fall on 29th, 30th and month depending the 31st. Is this possible? Its is being used to calculate amounts for certain days, for example the calender object places a date in Cell A1, which falls between 1st-28th, another column also has a date option, the date to be chosen cannot be before todays date, and cannot be after the 28th of any given month. Is there a way to restrict in the calender or would a if statement apply? OR would a more simple approach to use data validation? where as (A1=MM, B1=DD, C1=YY) so that D1=A1/B1/C1 ie. 07/22/09, so that when using D1 it would be a date format. which would be the start date and E1,F1,G1 for a new date, then use conditional formatting to restrict or prevent choosing dates before TODAY() for the second date colums, I know a message could be displayed for it if it is less then/prior to the current date, or should i have the data validation adjust (if at all possible)for the first set of date options?
View 11 Replies View RelatedI have cut and paste some code provided by members of this great forum to insert a row in a second worksheet at the same row number when one is inserted in the active worksheet. e.g. If I insert a new line at Row 14 in worksheet "admin" I also get a new row at Row 14 in worksheet "report".
Code is as follows:
Private Sub Worksheet_Change(ByVal Target As Range)
Set sourcebook = ThisWorkbook
Set sourcesheet = sourcebook.Worksheets("admin")
Set targetbook = ThisWorkbook
Set targetsheet = targetbook.Worksheets("report")
myRow = ActiveCell.Row
targetsheet.Activate
ActiveSheet.Rows(myRow).EntireRow.Insert
sourcesheet.Activate
End Sub
However, anything I do in worksheet "admin" triggers a new row to be inserted in "report".... If I change text in any cell, or make any changes at all, I get a new row in "report".
Is there a way to restrict this action to only a line insert?
I'm an intermediate Excel user that can navigate around pretty well, but now my boss wants me manipulate Excel in such a way that I cannot figure out how to do.
He wants the worksheet to be "locked" so that I cannot select another or "the next" cell unless the active cell I'm in has something entered into it. The purpose of this is so that when a manager is buying off (proofing and approving) my work, he can't put his initials in a cell next to the purchased item unless the cell that decribes the purchaed item is filled in. I'm not exactly sure what terminology to use when describing this, so forgive me if I'm being vague.
Can I restrict a user from "moving on" to another cell unless the active cell is filled in? And if so, how do I do this?
I was wondering if there was a way that I can have a user only able to edit the worksheet that pertained to them in a workbook of many sheets. So if there was a sheet called "Alicia" and another one called "Love Child"; user Alicia would only be able to update info on the "Alicia" tab and user Love Child would only be able to update their info. Is this possible? Also can this be done for a particular row in a spreadsheet? So if row 3 has Alicia's info, she's only allowed to update the info on that row.

I have a long list of data: a unique number identifier that needs to be grouped with text. Right now they are in two separate columns. I would like to have two large columns on a page, as if you were looking through a phone book. I have been trying to get this list to load into a finite number of rows before it breaks into another column on the same page. Then moves to the next page, so about 30 rows that are set 8 rows down on a page to account for company letter head.
I haven't paired the text and numbers together at all. But I haven't been able to find a way to have them move in a way that maintains their correspondence. I have gotten my numbers to move into the row column set I have wanted but not the text.
[LETTERHEAD] {1-7 rows}

View 6 Replies View RelatedI have two worksheets. One is called "Orders" and the other is "Invoice2".
On my "Orders" sheet I have a listed of product codes and ordered quantity. One column being ordered quantity and the other being product codes.
For instance it is like this:

TH1 5

On my "Invoice2" sheet I have a column for product codes and ordered quantity. Basically, I want the "Invoice2" sheet to reference the "Orders" sheet in relation to these columns. However, on the invoice I only want to display the product codes ordered and ordered quantity. For instance TH1 would be the first line and JC5 the second line. This is because AB3 is less than 0. So ever product code on the "Invoice2" sheet must be greater than 0 in ordered quantity on the "Orders" Sheet. This is what the invoice2 sheet would look like:
Product Codes Ordered Quantity
