i have some data in array format and want to use that data in the solver. However, as per my understanding solver takes in only ranges. How can i use arrays directly? this is wht i am trying, but not working
entities = 1
spread = 3 + entities
ans = 5
SolverOk SetCell:=spread, MaxMinVal:="3", ValueOf:=ans, ByChange:=entities
I'm trying to use Solver to determine an input parameter of the BINOMDIST() formula that provides the exact answer I want. It works for some inputs and outputs but not for all.
For example, I want 4 successes out of 7 trials to yield a 95% answer, meaning I need to itterate on the "P" input in the formula [=BINOMDIST(4,7,"P",TRUE) should result in .95]. Using solver it iterates successfully to .3413.
Now, change 4 to 6, and solver drives "P" to an answer that causes a #NUM result (P= 4.023), however I can manually input 0.6518 and I get the right answer.
I've tried adding constraints that won't let the input go outside the bounds of 0 and 1.0 but it does anyway.
FromToTriggerrange26Stop-lossrange25Combination triggerlevelie: 4Combination stop levelie: 5Profit $10
How can I make "Solver" run a check on which combination of trigger and stoploss that gives the highest profit? The range is in two different cells, but I can't get it working. I guess that it's my lack of skills, and not "Solver" that isn't complex enough.
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 have to use use the solver to calculate something (a mean-variance framework).
I am using the solver to minimize a cartain cell (variance) by making two cells equal through (expected return) by varying 10 cells( weights of assets), but I have to repeat this for 500+ times (for different expected returns).
Someone told me that I could best use some sort of loop through VBA. But I don't have a clue how that works.
I have a HUGE dataset (more than 1 million rows). I'm trying to find the optimum cell range size - 10 rows, 100 rows, 682 rows, whatever - for a SUM formula. (The formula would be in every row, looking down at the next n rows).
Is it possible to control the SUM cell range specified in a formula in cell (X) with a value in cell (Y)? In other words, the SUM formula in cell (X) would somehow refer to cell (Y) to determine the SUM cell range.
Ideally, I would like to then use Solver to find the optimal value for cell (Y).
Is this possible with just formulas? Or is VBA required?
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:
Private Sub Worksheet_Change(ByVal Target As Range)
ThisWorkbook.RefreshAll
End Sub
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?
With the inputbox I want to insert a numeric value to define a cell range, for example "C15:F15"
This is the code I'm using:
x = InputBox("Insert Row")
Range("C(x):F(x)").Select
Where (x) represents the Inputbox data (the number "15") I want to insert, But it doesn't runs
I would like an input box that asks users a select a range of cells....After this certain range of cells is selected....I would than like that range to be copied to a different sheet.

Is it possible to use an input box so a user can copy rows from a particular row to the last row that has data in it?
e.g row 23 & copy all rows from 23 to end od date (and then paste them to another location - e.g. nother sheet at the next empty row.
I'm trying to get a users' selected range to display in a cell as stored text.
therefore, If a user selects A1:D7. The text in Cells("G", 10) will be:"A1:D7"
w/o the quotes.
I've attached an example workbook.
Here's the formula thus far:
Sub SelectRangeBox()
Dim rnBody As Range
Dim vaMsg As Variant
Do
vaMsg = Application.InputBox( _
Prompt:="Please enter the message-text:", _
Title:="Message", _
Type:=2)
Loop While vaMsg = ""................................
Actuall maybe my thread should be Titled. user selected cell range displayed in input box save to cell as a text value.
I have a range (C3:C56). I have a set number in each of these cells. I also have a range out to the side that calculates a number after input a % in cell BI2. The formula reads as "=AE3-(AE3*$BI$2)". Basically it is reducing the values in my range. If a number is in my range is 8 and i input 25% in cell BI2, then my result would be 6.
I have a few steps I want to happen with this range.
1 Display an input box asking for a percentage
2 I want to loop through my range and use that percentage to reduce the numbers
3 (optional but would be amazing to have) after the reduced value is determined, round down to the nearest multiple of 4.
Is there a way of setting the input range on a combo box to a vale set in a cell?
ie, if my current input range is A2:A40 and i then users add another 20 records to that column, i need the combo box input range to change to A2:A60, so I can leave the sheet unmonitored for the users to add lines and not have to manually change the input range of the combo box.
I have a spreadsheet that has multiples ranges. Some values are displayed as negative values. I would like to create a macro that allows me to first select the range/s, (maybe using a input box) I want to change and then display the negative values as positive values.
Would I need to create a separate macro to do the opposite (change the values that are positive to a negative value)?
The other macro I’m trying to create is a similar type. What I would like this macro to do is first select the range I want to change and then divide all the cells in the range by 100000
I have searched for code in the forum to help me here but could not get any of the possible choices to work for me. I have a spreadsheet that is password protected but would like the user to be able to change the color of the fonts based on the user's choice. The protected page (one of many in the spreadsheet) has various cells that are unlocked so that the user can enter data. The rest of the page is locked. I have allowed all users of the worksheet to Select Unlocked Cells only. I have attempted to allow them to Format cells as well, but each time the program is re opened this feature is no longer working. (The program has a macro that ensures it opens in protected mode each time.)
So I would like to set up a Macro that allows the users to set the color of 6 rows and 5 columns based on their choice. An example of the configuration is:
1234Color Choice
A11016221
B21117232
C31218243
D41319254
E51420265
F61521276
Using the above format, I am imagining the I would have a Key with color codes (using the ColorIndex Properties). The user would type in the appropriate number for each row and click a button and the rows (5 cells each) would change to the selected color.
have a range of dates in a column i can match an input date with this code where the input date is in cell H20 (eg 04/04/2008)
With ActiveSheet
Range("D:D").Select
Range("D:D"). Find(What:=Range("H20"), After:=ActiveCell, LookIn:=xlValues, LookAt:= _
xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:=False _
, SearchFormat:=False).Activate
End With
the problem is that not all the dates in the range are consecutive and there may be the same date more than once eg
01/04/2008
03/04/2008
03/04/2008
05/04/2008
the problem is if the date in cell H20 (inputted by user) does not exist in column D, it all goes wrong.
what i would like to achieve is a way of incrementing the cell date by one day until it matches a date in the range, in this case if 02/04/2008 was entered 03/04/2008 would be picked up.
So I found a macro that does something similar to what I need.
I tried changing the data range and input column but it doesn't work.
What the macro does is I type whatever name into the msg box and it will copy and paste all the rows that contains the name to a different sheet.
Here is the macro:

Application.ScreenUpdating = False: vl = Application.InputBox("Enter value for Column B", Type:=2): If vl = "" Then Exit Sub

I have a column of hours spent working on a particular task, but I only want to add the hours that fall within a two week reporting period.
Is it correct to use the SUMIF formula? If so how do I write the formula to include the date range desired? Would it go under 'criteria'?
I am using the built in moving average function to calculate the moving average of a set of numbers. There are a few things that i would like to do.
First i would like to have the last result displayed in a single cell. Then next to that cell i would like to have a cell that would specify the period of the moving average. I would like to be able to change the period in that cell and have that change it in the actual function. And finally i would like to have the moving average in a chart that would also change its period once that is changed in the respective cell. I realize that this might need some VB coding which i am currently learning.
If possible could someone please help with changing the below code so that column "D" in the rngIn part of the code can be a variable. i.e so the user can select one, two, three or four columns (with visible data) to be copied. The "b3" part is a constant.

Excel 2010. I have a macro, stored in a workbook.
The macro is: collecting data from another opened workbook,processing the data,saving the processed data in yet another workbook.
The workbooks' names it is operating on are hardcoded in the macro. I'm trying to make it more flexible, that is to allow user to specify both source and target workbooks along with the data columns.
The workflow follows:
User opens both source and target workbooks,User opens the workbook with the macro,User runs the macro (with a button for example),Macro prompts the user to select range in the source workbook,Macro "memorizes" the range and the source workbook's name from user's selection,Macro prompts the user to select range in the target workbook,Macro "memorizes" the range and the target workbook's name from user's selection,Macro processes the data.
I found out that this can be achieved with Application.InputBox("Select cell(s)", Type:=8) method. However there are some issues that I was not able to solve playing with the returned value's methods:
The .InputBox defaults to active workbook. I was able to select another opened workbook only with Ctrl+Tab combination, but it will not work with the end users - they are too poor with these tricks. Is there a better, more intuitive way to allow user selecting a workbook?I was not able to get the workbook's name from the .InputBox returned value property. I was trying with .application.caption and .application.activeworkbook.name - none of these worked. They returned name of the workbook with macro, not the one with selected range. How to get the workbook's name from given cells range?
Trying to run a VBA to colour a range of cells based on the input of a name. I can write the basic level VBA to colour one cell by numerical input but struggling to see how this can be adapted to colour a range of cells and if instead of 1,2,3,4 etc the case could be replaced as text: eg Joe, John, Jason etc.

I want to create a script that loops through each row where it checks if an input range is over 0.
So it starts by me declaring what cells in row ex A5:A7
Then it loops through each row in searching only in column 5:7 if its over 0.
If it is, then mark those cells red..
Is this possible?
I want to create a macro which asks some information like functions do. For example, I would like the macro to ask for some data to be filled by the user. For that purpose I thought about using the inputBox vba function. I wanna fill the field in the inputBox with a reference to a range from an excel sheet. So, I click on a cell and then I try to hold ctrl + down cursor to get all the range starting from that cell on until the last consecutive filled cell on the sheet. Nonetheless, the problem I have is that when I do ctrl+down cursor, I just do not get the reference I want, because it seems that the ctrl+down cursor combination does not work in the inputbox for filling a reference to a range of cells. Does anyone know some workaround to achieve this?
View 9 Replies View RelatedI want to pass an array to a function, and am unclear how to do it. For example, the following declaration does not work:
Public Function xyz(a() as Variant) as Double
There is an additional requirement that I would like the output also to be a range of the same dimensions, typically one column and 100 rows. Is this possible?
A further twist is that the function I am writing calculates two values for every element in the input array and I need the output of them both.
An inelegant solution would be to write two separate functions, but I was wondering if it is possible to get two array outputs from a single function.
