I am trying to create a matrix in VBA with variable matrix size. The matrix I need will be anywhere from 3 to 9 columns and 15 to 30 rows. I want to set the size as variables and then create the Matrix using these variables, similar to:
rows = 4
columns = 25
Dim XMatrix(rows, columns) As Variant

Creating a Scenario Matrix. I am using Excel XP. Simplifying the problem, I have a formula;
Cell A1 has X,
Cell A2 has Y
Cell A3 has Z
X * Y = Z
I want to find the answers when X is between “1” and “5” and Y is between “1” and “5”. I want this to be in a matrix so I want the answers:
1 2 3 4 5
1
2
3
4
5
I cannot use Scenario Manager; it would record the answers on the pivot table or summary which is what I want BUT I would have to type every combination (1,1), (1,2) etc!
I have 1551 rows of port distances, as shown below.

I have a list of 206 ports. I want to build a matrix of Port distances with the names of the ports (206 names) on the first row and column and the distance from each port to every other port. I understand that the 1551 rows of data that I have is not sufficient, but those are he only significant ones. For the missing records I would like to put "zero" in the matrix.
Also, Once the matrix is built, how can I use it to find the port pair distance when the user inputs two port (From port and To port)?
I have the following used formula to count how many occurances there are of a particular piece of text in a column:
=SUM(IF(range="text",1,0))
e.g. {=SUM(IF(K6:K16="H",1,0))}
I have repeated this formula for an adjacent column
e.g. {=SUM(IF(L6:L16="M",1,0))}
I need to find a way of counting number of occurances in these two columns (K and L) when text "H" and "M" are present in the same row.
To further complicate matters (well for me anyway) the text "H" and "M" care chosen from a list of options in the K and L columns.
What i ultimatly want to do is create a matrix to compare how many times all possble occurances of the various options listed in both columns are present in the same row in the spreadsheet.
I need to create an array with a variable as it size For instance:
View 2 Replies View RelatedI am attempting to create a rather complex macro to format periodic raw data being made available to me; this data centers around a main column. The column of interest in these raw data reports is of variable length; I wish to apply a name to this column in order to make it easier to perform calculations. I know how to write VBA code to select every cell in a column down to the point at which the column becomes empty space, regardless of how much data is in the column, and I wish a include naming of the range in the macro. However, all my resources imply you must give the exact definitions of the range when writing the name application in VBA. Does anyone know if there is a way to include naming of a range in a macro without knowing the range's exact size? Put another way, is there any way to apply a name to an already-selected group of cells without giving the exact dimensions?

I am trying to figure out how to make a userform to display the contents of a 2-D array which has a variable number of rows. I want the userform to height of the userform to correspond with the number of rows of data to display.
I don't have much experience with userforms, but here's what I was thinking:
VBA code which would find the # of rows of data and then adjust the height of the userform and the length of the lable (which the data would go in).
I have data from 100 trials. Each trial has a variable number of data points (rows), but each row is labeled in the first column with the trial number. I would like a macro to identify the first row of each trial, calculate the difference of the value of the cell in column G of that row from a constant (718), and then add that difference to that cell and all other cells in that column of that trial.
So based on the attached sample, I would like all values in column G for trial 2 to be +1, for trial 3 to be -5, and for trial 4 to be +2.
In the file, I've cleared all the data from the impertinent columns. Eventually, I will also want to perform a similar process on column H but with a different constant.
I am trying to use a combination of dependent named ranges and variable length ranges, so one can select in eg Col A truck name from a drop down list, and then in Col B, the engine variant only for that make of truck. The indirect(substitute) function works well if I define the dependent range name (the engine variant) using actual cell refs. However if I use the variable length name definition as described in Ozgrid (ie with offset function), I get an error message and the dropdown menu freezes. Is there anyway to overcome this without resorting to VBA?

When an * is inserted into a single cell in column A, that Row number will become the variable in this equation:
=Sheet1!$G$'variable'
i.e. if i put a * in A14, then the formula should read (=Sheet1!$G$14).
How would I create a variable range with:
Sheets("output").Cells(I + r, 1):Sheets("output").Cells(I + r, 9)
I currently have the below macro:
If Cells(1, 3) = 2 Then
For a = 1 To 336
b = Round(a * 2 + 0.99)
Cells(b + 0, 3) = a
Cells(b + 1, 3) = a
Next a
MsgBox " Cell C1 is not equal to 2"
End If
where the intent is that whatever cell A1 is equal to, that is how many times over it will duplicate a number in consecutive cells before moving to the next number, ie:
1
1
2
2
3
3
etc to 336.
How can I tweak the code so that if I change the data in cell A1 to 9, I don't have to go in and change the macro?
I'm wondering if there's any way to put a variable for a cell address in an external reference formula. Basically, I'm creating an abridged report of customer data that takes a single customer's info from 2 other workbooks on a networked drive and compiles the chosen cell data into one worksheet summary of their info. The base external reference formula looks like this:
='F:Projects[CustomerDB.xls]Sheet1'!VariableCellGoesHere
I want to know if there's a way I can make the formula use a variable cell address that I can just type into another cell to tell it which row I need to grab info from. Generally, all of the customer data I need is spanned across multiple columns in one single row. The formula above appears multiple times in the sheet I'm trying to make. The first is for "Name", the next is for "Address", next is "Phone Number", etc. So for instance, if I want customer data from the main spreadsheet and that customer's info is on row 355, my first few formulas are:
='F:Projects[ProjectDB.xls]Sheet1'!$A$355
='F:Projects[ProjectDB.xls]Sheet1'!$B$355
='F:Projects[ProjectDB.xls]Sheet1'!$C$355
Is there a way I can maybe have a designated cell where I just enter the row number I need (e.g. 481) so the formula sees that number and plugs it into the cell reference above resulting in the formulas adjusting themselves to ='F:Projects[ProjectDB.xls]Sheet1'!$A$481?

View 1 Replies View RelatedI am working on a research project of which details cannot be disclosed. I basically have many worksheets which each contain 3D positional data and I am plotting overlaid graphs using multiple worksheets. I have gotten them to work where I manually enter the names of the worksheets, but I am trying to use the CELL("filename") command to get the current worksheet's name, then using a substitute command to change certain fields, then I would like to use the string name created by those functions to call a global variable in another worksheet which defines a range. I will try to give an example.
Say I have 3 worksheets for arbitrary measurements:
1) filename 1mm
2) filename 2mm
3) filename 3mm
I would like to graph all 3 sets of data in worksheet "filename 1mm", using the fact that everything in the filenames are the same except for the 1/2/3mm part. I have a template of which I will be copy/pasting data from numerous data sets and then each worksheet has defined names "X_vals" and "Y_vals" which give me dynamic ranges for the data I wish to plot from that worksheet.
When I type the names manually--i.e. " 'filename 2mm'!X_vals" everything works fine, but when I try to create the exact same string dynamically using indirect/substitute/left/right etc, it does not let me do it. I am able to create a dynamic string with a range, such as " 'filename 2mm'!C10:C100" but then when I change it to " 'filename 2mm!X_vals" it just gives me #REF!.
I guess my question is just is there any way to use the indirect function to create a string name dynamically which references a defined name in another worksheet? If not possible with just simple excel functions, is there a way to do this with a macro? I am not exactly familiar with VBA in excel, though I know how to run macros.
how do we do something like Range("A1:B2") using an index for the cells. For example Range(R[0]C[0]:R[i]C[j]) which doesn't work. I know about Cells(i,j), but that only returns a range object of a single cell.

I have a strange problem I cannot solve in that I'm trying to create an auto filter that returns records based on a date variable.
If I set the code to equal the date variable, it returns information. If I set the code to return records AFTER the date, it returns nothing.
Code to return records on the date:
Dim startdate As Date
startdate = Format((Now), "dd/mm/yyyy")
ActiveSheet.Range("A:B").AutoFilter Field:=2, Criteria1:="=" & startdate
This returns data, however if I slightly amend it to get records on or after the date:
Code:
Dim startdate As Date
startdate = Format((Now), "dd/mm/yyyy")
ActiveSheet.Range("A:B").AutoFilter Field:=2, Criteria1:=">=" & startdate
It returns nothing. Is there a syntax problem in my code.
