I am trying to assign an array element to select a specific cell then assign a value to it. Below is the general code that I am working with. Does anyone know why this is not working?....
View 8 RepliesI'm only starting to get to grips with arrays. I have what I consider to be a lot of data that I need to 'cut' into separate workbooks. I have written some code that does this by simply looping through each line, 250k+, checking against a variable and copying the row into a separate sheet. This took longer than it would have doing it manually. It was suggested to me that I use arrays to speed up the process. I have managed to store the test data into an array but am struggling to find a way to loop through and pull out an entire 'row' from the array based on a variable. I have looked for 2 days in various places to find some way to loop through the data held in the array, but to no avail.
That code will appear here from about 8am GMT tomorrow. I know that once I've cracked this I'm on the road to some very significant time saving and comprehensive report writing.
I've tried to multiply each element in a 6x6 array by a similar 6x6 array, both on the same sheet, and it worked.(see Macro2 and attached xls file "Test").Then I got more ambitious and tried to do the multiplication from a standard array in sheet "TestA", with the result on the same sheet, by each array in sheet "TestB" and failed.How do I solve this problem? Pgualb PS:I'm using the R1C1 style.
Sub Macro2()
For y = 29 To 34
For x = 2 To 7
Cells(x, y) = Cells(x, y - 27) * Cells(x, y - 18)
Next x
Next y
End Sub

'Multiplica matriz em TestB por matriz padrão em TestA com _

I have 9 named ranges on worksheet Sheet1. I want to print every combination of every non-singular range on worksheet Sheet2. Below is a simplified version of the scenario.
There are three named ranges: Letters, Colors, Animals. Say the below are the entries for each range.
Letters = {A, B, C}
Colors = {Red, Blue}
Animals = {Dog}I want to print every combination of Letters and Colors but exclude Animals since it only has 1 entry.
Therefore my result would look something like this:
A Red
B Red
C Red
A Blue
B Blue
C Blue
My thought is to make a multidimensional array GrandArray where GrandArray(1) = Letters and GrandArray(2) = Colors, then recursively go back through every combination and print to Sheet 2. I can set up GrandArray, but stepping through each element is creating mismatch errors.
I'm trying to avoid For loops since my real data has 9 ranges which may or may not be included in the final print.
How can you test that no single element of an array is equal to a particular value?
I am trying to sqaure every element in a dynamic array and display the result . I donot understand how can I select the value in the cell using VBA?
Dim Y as variant, d() as double, i as long, j as long, rows as double, cols as double
Set Y = Application.InputBox("select the matrix: ", Type:=8)
Rows = UBound(Y)
Cols = UBound(Y, 2)
ReDim d(1 To Rows, 1 To Cols)
for i = cols
d(1,i) = ______==>
How do I select the value of element in that particular cell and how do I sqaure it?
I know
cells(rowindex, columnindex)
is used to select a particular cell but If I have a large array it would be difficult to go cell by cell and sqaure it.
I need to multiply matrix variable by a constant (each matrix entry has to be multiplied by the constant).
Sub Matrix()
Dim X As Variant, Y As Variant
Dim a As Integer
a = 2
X = [1, 1, 1; 2, 2, 2; 3, 3, 3]
Y = X * a ' Here it writes that type is mismached
End Sub
I read that in cell functions it is possible to do such calculations.
I am trying to pass information that is filled by user in a userform into an excel sheet. Let's say a user would click on a control button in a userform and Macro would ask him what value to store for the first variable. If user clicks one more time then Macro would identify that it was a second click and ask what value to set for a second variable. It is easy to do with limited number of variables, but is it possible that the variable which stores a number of clicks would become a number for variable to store the value?
1 click - a1 = ..
2 click - a2 = ..
....
n click - an = ..
If not possible - which way to search a solution?
I am trying to write a code for simulating a stock price using geometric brownian motion. I have the function part down as follows:
Public Function SimStock(Initial_Stock_Price As Double, _
Expected_Return As Double, _
Volitility As Double, _
End_Time_Days As Double, _
Number_of_Steps) As Double
SimStock = Initial_Stock_Price * Exp((Expected_Return - Volitility ^ 2 / 2) * (Number_of_Steps / End_Time_Days) * NRnd2() * Sqr((Number_of_Steps / End_Time_Days)))
End Function
Now what i need to do is to apply this to an array. so that when i run the sub it will simulate prices from today up to some number of days that i specify. This number of days will be equal to "End_Time_Days" which is part of my function. Furthermore the simulation has to be such that it uses the above formula for the first entry but then replaces "Initial_Stock_Price" with the result of the preceding entry in each subsequent entry.
My question is about assigning strings to an array.
The following code searches a cell for three strings (said, told, asked):
I am trying to assign a range of values with different types( date,time,integer) to an array. I am using the following command which works fine.
Dim vArr() As Variant
vArr=range("A1"). currentregion.value
However when I try to print the "time formatted" values in the second column of the range I can't. I can't use timevalue function as well cause it doesn't treat the values as string but integers. Why is this happening even when I declare the array as variant?

I have a number of cells which are connected to various formulas. EX. A1 = 7. Well I want a formula in A2 which can look at A1 and if A1 = 5-6, then A2 = 1, if A1 = 7-8, then A2 =2, if A1 = 9-10, then A2 = 3, if A1 = 11-12, then A2 = 4. And so on.

I have a macro which retrieves data from web.It works fine.I just don't know how to assign a cell value in web address.i have attached the code here. i just want to assign activesheet.(range"c2").value for "q?s".
View 1 Replies View RelatedI'm attempting to create a macro that will look at the total in column (K) and send an e-mail to two different addresses, depending on the amount. If the amount is over $10,000 then one address (over@macro.com) if under, then the other (under@macro.com)
My main problem is that I never know what cell the total is going to be in.
I currently have all quotes going back to the person that sent in the request, no matter what the amount. Their e-mail is in the sheet.
So what I think I need to do, is find the last cell in column K with data and assign it a variable. If that variable is over $10,000 then I can send the e-mail to a hard coded address. If it's over, I just use my original code.
I am trying to select specific values within an array.I have two tables, weight table and a factor table. These tables are a lot bigger than the example. I am trying to multiple the weights times the corresponding factors and then sum the result in one cell using arrays.
The third table is the result I am looking for. However, I would like to use some type of index/match or choose to get the result but cannot figure out how to do it. A couple of functions that I tried that did not work are next to it.
The index fails because the index function does not output an array (The result of the index function is just 4% instead of {4%,3%,4%}). The choose fails because the choose function does not select values within an array (ie I would have to put each factor as a separate value (F4,G4,H4) rather than the entire array (F4:H4). There are so many factors that I would like to avoid that.)

I have a problem with a listbox on a userform. I have an array that is stored in a name. The array has 2 columns and + 1000 rows. It looks like this:
100 Name1
110 Name2
120 Name3
Etc.
The listbox is filled from the array:
Private Sub UserForm_Initialize()
frmZoeken.lstbx_Gbr.Clear
frmZoeken.lstbx_Gbr.ColumnHeads = False
Dim myArr()
myArr = Evaluate("varRekSchema")
frmZoeken.lstbx_Gbr.List = myArr
End Sub
When the form with the listbox opens, it has to select by default the value in the listbox that corresponds with a value in a cell in the workbook:
Private Sub UserForm_Activate()
'On error resume next
frmZoeken.lstbx_Gbr.Value = Cells(ActiveCell.Row, 3).Value
frmZoeken.txt_Zoekterm.SetFocus
End Sub
When opening the userform the following error message appears: Could not set the Value property. Invalid property value.
When I activate the row "On error resume next" the listbox is correctly filled. The error occurs with selecting the default value.
I have written the code below. And I found two problems:
1.The code stopped to work when I change from Paste to PasteSpecial.
Sub Copyfriction()
Dim DestWB As Workbook: Set DestWB = ActiveWorkbook
Dim DestWS As Worksheet: Set DestWS = ActiveSheet
Dim DestCLL As Range: Set DestCLL = ActiveCell
Dim UserChoice
UserChoice = Application.GetOpenFilename(FileFilter:="Text Files (*.xls),*.xls")
[Code] ........
2.As you see the right cell on the the destination sheet need to be selected. So Im planing to run the macro when double clicking the cell in question. I have tried the next
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
If Target.Address = "$A$6" Then
Copyfriction
Cancel = True
End If
End Sub
I am calculating multiple Correlations for long lists of data. I want the correlation based on the value in a given column. In the below example I would like a different correlation for each value in colA and the correlation will be between colC and colD. ColB lists the different people whose data are used for the correlations. In actuality there are 30 or more people for each test. In every case ColC is the same for a given value of ColB (although I doubt that matters). The number of people taking each test varies. I would like a correlation of ColC an ColD for each value of ColA.

I need to query table contents where some general items are met, and item id's are not contained in an array.
Example:
Code:
SELECT LOOKUP.*, LOOKUP.Var FROM LOOKUP WHERE ((LOOKUP.Name)="test" Or (LOOKUP.Name)="test2" AND ((LOOKUP.Type)=3) AND ((LOOKUP.Var) ("array", "of", "items")))
I need to know how to add an array to a query since I can't hard-code the list each time, and the array can be a different size each time, so using array variables doesn't make sense here.
I have a problem with the following code.

I'm working on a tracking spreadsheet that needs to be able to function on both Excel 2004 for Mac as well as Excel 2007 for PC. The code below is written to ask for a date when the status of a particular row of cells is changed to a value other than "". These cells have validation lists where the list itself is just below the cell in hidden rows. It then places the date entered in the corresponding cell to the right of the list choice in the hidden rows and the top row is simply a vlookup to show the date with the status choice.
This way, when the status cell is changed again, it retains the date in the hidden rows while setting a different one. The code below is obviously not the full code, the whole code includes other functions and is a bit long, but I've narrowed it down to this:
I am trying to do something that sounds fairly straightforward but have not been able to achieve the final result.
I have a sheet which has multiple range addresses stored in different cells and so far I have been able to pass the Range address to Range variables by looping through a range array. Now I would like to select these multiple ranges. My code looks as below;
VB:
Dim Cnt As Integer
Cnt = Sheets("Sheet1").(Range("1040").Value ' Cnt holds the the total number of ranges to be specified in Sheet1
Dim RStr(1 To 80) As String ' This will hold the range addresses specified in Sheet1 in cells C1041 to C1120. Upto 80 range addresses could be specified.
[SIZE=2] Dim Rng(1 To 80) As Range ' This will store the ranges based on the range addresses stored in RStr()
Dim i, j As Integer,
[Code]...
I am not sure on how to select multiple ranges using range array hence tried Union() however it is obviously not correct and throws an error.
I searched and found that to assign a name to a label based on a cell value requires the following
Label1.Caption = Worksheets("Sheet1").Range("A1").Value
which would assign the value in cell A1 as the caption for Label1. I've got a range of values in cells:
C4:N4
and I'd like to assign them as names to labels 1 through 12. How would I do that using VBA?
I'm trying to do, I already have a macro that takes certain cells in sheets in a workbook and copies to them to individual workbooks that are open.
So for example, I have a workbook with sheets A, B, and C.
and then I have a macro that'll copy sheet A to an open workbook D and B to an open workbook E, and so on.
Problems I'm running into = if the workbook isn't open, it crashes, I'd like to have an if then statement where if workbook is not open, it stops?
Additionally, I'd like a for statement because there will be 10 or more sheets in total, so would be nice to have a for statement that changes the variables so For i = 1 to 10 where 1 would be D and 2 would be E and so on so it automatically changes the workbook names as necessary.
I see that IF statements can only be nested 7 times. How do I create a cell that checks to see what item was selected in the dropdown box of 20 different choices and choose a particular cell range depending on what is chosen?

As you can see the letters repeat, and the dates are in order. Dates may repeat or be skipped.
I want to know how I retrieve the last date in the list that corresponds to a certain letter. For example, the last date that corresponds to "A" is 10-Jun-12. Similarly for "B", it is 11-Jun-12.
VLOOKUP will retrieve the first day.
In this case corresponding to "A":
=VLOOKUP("A",A2:B12,2,FALSE)
Is there any way I can retrieve the last day with a formula?
