Fastest Way To Reference A Cell - Range() Or Cells() ?
Dec 22, 2008
I have a loop that executes roughly 7.7 million times when my VBA program runs. Neednless to say it take a long time to run - usually a couple days.
The inner-most loop contains a line of code from way back in my early vba programming days when I knew even less than the small amount I know about programming now (and if you can follow that sentence you might be able to understand some of the spaghetti code I write :-) ).
for k = 1 to n
if Worksheets("Personell").Range("D" & Trim(Str(k))) > dtCompleted then ...
Would it be faster to use this syntax (which I just found out about):
if Worksheets("Personell").Cells(k,4) > dtCompleted then ...
It would cut out 2 functions calls, trim() and str(), so it would be faster, right?
I am almost embarassed to post the Range("D" & Trim(Str(k)) line of code because it looks so convoluted now, but that's how I learned to program, just fumbling through until it ran...
So in short, I just wanted to confirm that the cells() syntax run faster before I spend an hour editing and tested.

How can determine if a range is empty without looping it till the first value is found? On a 5x5 range a for loop is not that bad but what if its the whole worksheet? Is there a fast way to do this?

I have a range of purchase order rows, with the formulas stored in the first row (TemplateRow) which is hidden. The users may add any number of rows to this range, depending upon the number of different products being purchased.
Code:
'Copy the template row into the first newly inserted row
Rows(TemplateRow).Copy Destination:=Rows(insertionPoint)
'fill down from the inserted row down to the last new row
With Rows(InsertionPoint & ":" & NumberOfInsertedRows.Rows.Hidden = False
.FillDownEnd With
The problem is copying the formulas down to the new rows can take terribly long (minutes) in scenarios of thousands of products. Is there a faster method of copying down my formulas?

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.

I have 5 columns set up: A,B,C,D,E
D is the sum of A and B
E is the sum of A,B,and C
As I add in a new column to the right of C (call it C2), I need D (which has shifted over one) to sum A,B, and C.
I also need E (which has also shifted over one) to sum A,B,C, and C2.
Essentially I need a function in a cell that will be able to reference two cells to the left even as more cells are added.

I have lets say 12 months of data. I have formulas that reference the latest 6 months. When I insert a new column to input a new month, how can I make the formulas include the new months without manually updating them.
EXAMPLE:
12 months of data exist in cells B3:M3 going from B3(oldest) to M3(newest). Formulas reference latest 6 months of data in cells H3:M3. When a new month hits, I insert a column after column M.I would like the formulas to now reference cells I3:N3 which is now the newest 6 months.

I have a 'receipt' worksheet with about 500+ lines of data, here is an example of what could be in cell A166: 1.1 NET_AMOUNT 742,523,253.83
In another worksheet, is there a way to look at the whole worksheet for column A in receipt to say:
if 1.1 is true, capture text to the right of 'NET_AMOUNT' then format using =Dollar?

I've been trying for a while not to reference a range of cells in closed workbooks to create an ongoing automatic log.
I've attached a test log with the details required and the cells are staggered, I have been using the formula;
='NETWORKPATHFOLDER[121113 12.42.xls]Enquiry Form'!$G$1
then the cells are (SAME PATH) J1, A5, A7, A9, A11, A13, A15, A17, A19, A21, A31, B31, E31, J31
and the attached test will placed then in that order under their respective headers.
So, all in all, is there a VBA code where it can run it from closed workbooks in the order above?

I have a workbook where one tab contains the data that I am given:
Project-A data1 data2 date1 date2 date3
Project-B data1 data2 date1 date2 date3
Project-C data1 data2 date1 date2 date3
Project-D data1 data2 date1 date2 date3
In another tab, I have a report where a row containd the project name, and I want to find the maximum value of the dates in the ither tab, where my project name matches the project name on the tab data I am given.
So, if I have "Project-C", I need to know the max of the dates in the row for Project-C; but I dont know what row that will be on in the other tab. For info such as 'data1' I have been simply using vlookup using the project name as a key.

Using VBA, I am importing data from Access (Access2007) into Excel. The code that I use works as required but I need to refine it so that I can filter for the records that I need to import. I can import ALL records. I can import selected records by manually changing my SQL query. I would like to reference an array of values or a range of cells so that I do not need to manually change my query every time I want to run it.

This code gets all records for "Jeff" and "Bob" from the Access database. I need to query about 100 names at a time so manually inputting them is going to take forever. How I can make it work?

I often have problems with the cells range reference method. For some reason I get an error and can't tell why. Other times it works fine. Is this just an unstable method to use or is this completely wrong? I'm assuming I am using the wrong syntax. It is definetly the range reference causing the problem.
Dim cnt1 as integer, cnt2 as integer,cnt3 as integer
cnt1 = 2
cnt2 = 50
cnt3 = 2
dim myrange as range
set myrange = sheets("sheet1").range(cells(2,cnt1), cells(cnt2,cnt3))
I have no idea why it won't work. I'm basically searching a columner range of cells.

I have a data that is split into multiple cells and needs to concatenated. Unfortunately, the number of columns wherein lies the data varies throughout the workbook. As such, I wanted to select a range of cells, define this range as the reference point for the macro, run the macro, then move on (selecting a different number of columns on the next try).
For example, I have this:
A
B
C
D
E
1
No
Not Very Far
[Code] .....
I want to select cells A1:B1, run a macro concatenated the two columns, then select cells C1:E and run the same macro to get this:
A
B
1
No
Not Very Far
[Code] ........
So far, I have this:
Code:
ActiveCell.Columns("A:A").EntireColumn.Select
Selection.Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
ActiveCell.Offset(5, 0).Range("A1").Select
ActiveCell.FormulaR1C1 = "=CONCATENATE(RC[1],RC[2])" '

I've been trying to get the sum of a range of cells based on their relation to the active cell. Here is the Pseudo
If the SUM of (the cell 2 rows up THROUGH the cell 2 rows up and 2 columns to the left) = 0 then .......
*****end pseudo
I think that activecell.offset is the best way to do it, but I can't figure out how to work that in a range....
Here is my code so far:
Worksheets("Generic SPC").Activate
Worksheets("Generic SPC").Range("c2").Select
'Do for all cells in the row
Do
ActiveCell.Offset(0, 1).Select
If Application.WorksheetFunction.Sum(Range( _
ActiveCell.Offset(-2, 0), ActiveCell.Offset(-2, 2))) = 0 Then
ActiveCell.Value = 0
ElseIf Application.WorksheetFunction.Sum(Range _
("ActiveCell.Offset(-2, 1), ActiveCell.Offset(-2, 3)")) = 0 Then
ActiveCell.Value = ActiveCell.Offset(-2, 0).Value
Else: ActiveCell.Value = 0
End If
Loop Until IsEmpty(ActiveCell.Offset(0, 1)) = True
******End Code
Range doesn't like activecell.offset. Does anyone know how to do this?

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?

I have a workbook with two sheets. The first sheet is the data sheet.

104 20 23 CR39601P 104 10420 1042023 1042023SPR
The next sheet is where the magic happens. Separate this worksheet into two sections. The reference section (column A and B) and the entry section (column E-G). Column D is a formula that will concatenate column E-G together. In the entry section any number of combinations can be entered. In the reference section I need to take the style number and reference it back to the data sheet. Then take the possible combinations from that style (column E and greater) and see if any of those combinations exist on the other sheet in column D. If so then say added....otherwise say needed.
"....In Pricing Sheet" is where I am looking to put needed or added or something like it.
A B C D E F G
STYLE …IN PRICING SHEET Concat DEPT MCL SCL STYLE
CR10600S Added 1042021 104 20 21

CR10603S Added
CR10603SX Added
CR49605S Added
CR49605SX Added
CR39601P Needed
Any ideas on how to do this in formulas and without code? I have tried and looked into index, match, dget and lookup. I just don't think I am finding the right combination of formulas.

i need to copy a range from one workbook ("weekly data") to another ("Yearly data"). The range to copy is called 'weekly data'. The ranges to paste to are called 'week 1' through to 'week 52' (this is the yearly data sheet). On the yearly sheet there is a cell Po1' that week on week will state the week number ie 'week13', 'week14' etc. code to use this data in 'P1' to tell the macro to copy to the appropriate week. I have attached as far as i got (then failed due to lack of experiance).
presuming that both books are open
HTML windows("weekly data").activate
sheets("weekly transfer").select
range("weekly data").copy
windows("yearly data").activate
'only one sheet in workbook
range ' data from p1 .paste

I have a list of headings and items and I have a set of formulas that work out depending on the heading what items are listed.
Say theres 10 items and the heading starts at C4 and that heading has 10 items, so it puts "C5" as text in G1 and "C15" as text in G2 so i now know my cell range of items
How can i use the text in those cells to put in a formula to call that as a range?
If I use the indirect formula it shows me the value of the cell, but im after using it to reference the cell

I have a variable which contains the column number. How do I then reference a range in VBA using that column number, as opposed to the letter? I know how to convert the number into the letter, but I also know there has to be something more simpler. For instance, a form of the ADDRESS function, but in VBA?

I have a list of numbers in Column A and in Column B I have a standard Sum formula which sums the adjacent number in Column A and the four numbers before it.
A B
1 =Sum(A1:A5)
3 =Sum(A2:A6)
5 ...
3 ...
5
6
I would like to have a formula which references another cell to define how many rows to sum from the starting cell. So in the above example, the total number of rows which are added together is 5. If I wanted to change all of the SUM formulas to add 6 rows, I would like to be able to change the number in the reference cell to 6 and all of the sum formulas would switch to adding 6 rows.

I am running Excel 2003 on a Win7 system.
Here is my situation:
Each of my data sets spans roughly 75 columns by 250 rows at present, but this could expand. The first 7 rows contain metadata. Columns 2-25 or so contain the raw data, from which everything to the right is calculated. The data sets have most columns in common, but not necessarily all.
In order to tease out the most meaningful information from my data, I frequently sort all or part of it based on varying criteria. When I find a useful sorting criterion, I create a new column with a header that describes the criterion and populate it with a formula that returns a 1 if the condition of interest is met for that row, or a 0 if it is not. For example, if I am doing this in column AA, I might enter
=--(AND($AX8>$AA$4,$Y8>0))
and copy it down to the end of the data. The resulting vector of 1s and 0s quickly re-identify data that meets that criterion even after subsequent resorting. It also makes locating data that meets multiple sorting criteria extremely simple. Essentially, I create a truth table.
Cell $AA$4 in the above example contains a "comparator" value I might wish to change at some point, which would change the subset of data the condition selects for.
Here's the first hard part:
For each data set, I need the ability to generate meaningful plots that includes separate series based on the criteria I have described. However, I also need to retain the ability to resort the data or change the comparator value without disrupting these plots. In other words, the plots must NOT change when the order of the data is changed, but MUST change to display the appropriate data when the comparator changes.
Here's the 2nd hard part:
Once I have this working for one data set, I need to be able to port it to other data sets (which are contained in other workbooks), so that I can compare equivalent plots from each. I also need to minimize the number of manual steps involved in doing so, to avoid human errors and excessive time consumption.
The only other possible complication I can think of at the moment is that, to this point, I have been inserting blank rows to isolate subsets that I do not wish to perform further sorting on from each other.
Right now I am angling toward VBA code that loops through the entire data set to generate base dynamic ranges using the column header row (row 1) as the names, and the entire column of data for the rangeloops through the truth table columns to generate "branch" row ranges for each of the sorting conditions,loops through the entire data set one more time to create "branch" ranges for each of the base ranges.
I could generate some code to accomplish a one-off solution for a given configuration of a single data set (provided there is not a list length limit in a chart series that I'd be violating)...but without a dynamic named range, I don't know how to get to something that would update appropriately. So in essence, I am still stuck at the dynamic range part of this.

I have a formula which is using named ranges-
=SUMPRODUCT(xxx-30,Ship_30)/SUM(Ship_30)
where Ship_30 name references the following-
='sheet 1'!$C$20:$C$38
The value of 20 is static, the value of 38 is dynamic. Each new time period adds another value (i.e. 39,40,41)
Having to edit each name range reference in the name manager is not acceptable since there is potentially over 30 to edit each month.
I would like to edit a cell which would have contained the value 38 (or C38) with a new value of 39 (or C39) so the range reference would be updated with the new value.
The goal would be to have a couple of rows with the following that could be edited with new values

I'm working with a very complex financial workbook with over 3,000 named ranges and would like code to replace the named ranges with the cell references and display it in a message box so the user can easily trace the references without removing the named ranges from the formula. There is a lot of code with the named ranges, so actually converting them to cell references is out of the question.
I found this code, but obviously it physically replaces the range names in the cell. Hopefully it can be converted to display it in a text box.
Code:
Sub FixReferencesToCellNames()
Dim c As Range, n As Name
For Each c In Range("A1:IV65536").SpecialCells(xlCellTypeFormulas)
[Code]....
What I am looking for is that a user select a cell that they want to see the references, run the code to see the cell references for that particular cell in a message box.
