I recorded a macro using 'Solver'. When I try to run it, I get a message"Complie Error: Sub or Function not defined". Can anyone help me?
Heres the
Sub Macro1()
SolverOk SetCell:="$R$4", MaxMinVal:=3, ValueOf:="4275", ByChange:="$S$4"
SolverSolve
End Sub
I also tried this
Sub SolverMacro()
' Example Solver VBA Macro
SolverReset
SolverOk SetCell:="$R$4", MaxMinVal:=3, ValueOf:="4275", ByChange:="$S$4"
SolverSolve userFinish:=True
End Sub
I was able to find a solution using the excel solver add in but unfortunately it cant take more then 200 constraints and hence gives an error. I am unable to find a different approach to this problem.......
I am using Excel's solver to work out an integer problem. Although the answers are indeed integers, the number in the formula bar is not. For example: although 7 is the answer, the formula bar give 6.99987584. Even if I try to format the cell for 0 decimal places, it does not correct.
I have a little spreadsheet aplication which ran perfectly in Office 97, but since the move to Windows/Office XP, I get the message:
Solver: An unexpected internal error occurred, or available memory was exhausted.
I'm running a P4 2.26GHz with 512MB RAM.
My code is as follows:
Public Processing_Message As String, Macro_to_Process As String Public StartTerm As Integer, StopTerm As Integer, StepTerm As Integer Public ResultsLabelCount As Integer Public myErrorFound As Boolean Public rs As Object Public ctl As Control
I have a macro that does a solver routine. I have another macro that runs this solver, then copies and pastes new inputs, then runs the solver, then copies the results and pastes them somewhere, then copies new inputs, etc. It is a long process and it worked fine a few days ago. Now when I run it, about 90% of the way through and then excel crashes. The error says:
Solver: An expected internal error occurred, or available memory was exhausted.
I get this error : Compile error : Sub or Function not defined. I found out that this might be caused by the solver not being referenced. But, this is fixed now but I still get the same error message.
I'm using Excel 2007 - Windows.
Here is the code :
Sub Macro1() Dim i As Integer Dim j As Integer j = 4 For i = 1 To 4000 If ActiveSheet.Cell(i, 12).Value = 1 Then ActiveSheet.Cell(j, 15).Value = ActiveSheet.Cell(i, 2)
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 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?
I am trying to drive Solver in Excel 2000 with a Visual Basic (version given as 9969) macro. SolverReset is observed, and SolverAdd puts the constraints in. But the SolverOK statement does nothing, so the SetCell and the ByChange windows stay empty.
SolverSolve is trying to do something, because the spreadsheet cell that should receive the return code from Solver gets an error value #VALUE! (The macro then stops, unable to process this entry.)
Solver is checked off ok in the References list in V.Basic.
The same macro, same spreadsheet, in the same Excel file, works fine on the other computer in my office with what I am told is a more recent version of Excel; i.e. this doesn't look like a coding error.
I wanted to see if I could use the solver to Solve Sudoku puzzles. I created the attached workbook. First it colors the numbers that are put in manually, which would be the starting puzzle. I have a generic one put in now. Then it finds which cells that are allowed to change. Then it is supposed to solve. It doesn't work. Run the Sheet1.SolvePuzzle Macro to see it not work. Is solver just not up to the task, or am I missing something?
I need to solve this using solver. I have an idea, but I'm not sure what to in regards to my objective function, and how to properly set up my constraints. I know I need to use sumproduct, but I'm not sure in what way. I'm using Excel 2007, here is the problem:
The Sweet Smell Fertilizer Company Markets bags of Manure is Combination of compost and Sewage Wastes. Each pound of Compost costs sweet smell $0.05 and has a fertilizer rating of 2 units. Each pound of sewage costs $0.004 and has a fertilizer rating of unit. To provide good quality fertilizer, each bag should contain at least 35 pounds of compost, not more than 40 pounds of sewage, and have total fertilizer rating of at least 100 units. Determine the lowest-cost blend of compose and sewage in each bag.
I created a trendline and associated equation for some data plotted against Time on the x-axis displayed in MM/DD/YY format. The date for the data ranges from 3/27/06 thru 11/10/08.
The data actually crosses the y=0 line around 11/5/07, which is the data root
When I use Goal Seek, I got a zero root solution of 28154.98. When I convert this to the date format, it converts to a date in 1981 which is not correct. I tried a range of initial guesses but they all converge to the same number.
I am using solver to solve an optimisation problem I have. I need to apply a new solver to every populated row of my sheet. My solver code is as follows:
Sub solverloop() SolverOk SetCell:="$Z$2", MaxMinVal:=3, ValueOf:="0", ByChange:="$N$2:$O$2" SolverSolve End Sub
The code above applies the solver to row 2. My sheet has roughly 500 populated rows. I need to write a macro to loop solver over each row, accept the solution provided by solver, then move to the next row. i would also like to close the loop automatically when the last populated row is reached.
I'm trying to run a macro which will allow me to run solver and keep the solution.. I have managed to get the macro to work. However, does anyone knows how I can ensure that solver's solution can be automatically saved without prompting the user whether to save the solution?
I am having problems with this excercise on my worksheet in my business computing class. I was wondering if someone could guide me through on how to use the solver feature.
Excercise: Eve Blue is the manager of Southland Furniture store and she is planning a New Years Day sale. The store has only 75 square feet of space available to display and stock this merchandise. During the sale each folding table costs $5, retails for $11 and takes up two square feet of space. Each chair costs $4, retails for $9 and takes up one square foot of space. You must order at least one chair and one table and, of course, they must be whole units. The maximum amount allocated for purchasing the tables and chairs for the sale is $280. Eve cannot sell more than 40 chairs but the demand for tables is unlimited. Eve asked you to help her determine how many tables and chairs she should purchase in order to make the most profit.
Layout: (I marked in x's where I need to solve.)

At work, we have a spreadsheet that uses SOLVER.XLA in a macro. It works fine in Excel '97 but in Excel 2003 it simply does nothing. The code is
s = Application.LibraryPath & "solversolver.XLA" On Error Resume Next Workbooks.Open filename:=s Application.ExecuteExcel4Macro String:="SOLVER.XLA!SOLVER.RESET()" Application.ExecuteExcel4Macro String:="SOLVER.XLA!SOLVER.OK( PLOT!R46C4,2,0,(PLOT!R13C12:R14C12))" Application.ExecuteExcel4Macro String:="SOLVER.XLA!SOLVER.OPTIONS(100,100,0.000001,FALSE,FALSE,2,1,1,0.05,TRUE)" Application.ExecuteExcel4Macro String:="SOLVER.XLA!SOLVER.OK(PLOT!R46C4,2,0,(PLOT!R13C12:R14C12))" Application.ExecuteExcel4Macro String:="SOLVER.XLA!SOLVER.SOLVE()" ActiveSheet. Protect DrawingObjects:=False, Contents:=True, Scenarios _ :=True, password:="sigma"
It gives no error message, it simply does not do the calculations. (I took out the error handling line to make sure that there really were no errors being generated!)
I have the following dataset and was wondering how I can run a constrained regression in Excel with the constraint being that the total allocation of assets is 100%:
Total return (y): 12 data points Asset 1 (x1): 12 data points Asset 2 (x2): 12 data points Asset 3 (x3): 12 data points Asset 4 (x4): 12 data points Asset 5 (x5): 12 data points Asset 6 (x6): 12 data points
[Attached is a spreadsheet with the actual dataset]
I know the regression equation I need is R = b1X1 + b2X2 + .+ (1 - b1 - b2 - .- b5 )X6 + e
When I run a group of macros for some reason after the marcro runs and I hit F2 excel crashes.
I have figured out that it is one of the marcros that makes the excel crash. It is only when I run the solver application. The code is below. Any thoughts why hitting F2 after running this marcro would crash the machine?
When I go to excel ==> ALT + F11 ==> Tools ==> Reference ==> I can't seem to find "solver" anymore. My code was using the solver module, and now my code does not work. I can't find "solver" to check it.
