I have two bits of code. First a standard copy paste from cell A to cell B
Sheets(sheet_).Cells(x, 1).Copy Destination:=Sheets("Output").Cells(startrow, 2)
I can do almost the same using
Sheets("Output").Cells(startrow, 2) = Sheets(sheet_).Cells(x, 1)
Now this second method is much faster, avoiding copying to clipboard and pasting again. However it does not copy across the formatting as the first method does. The Second version is almost instant to copy 500 lines, while the first method adds about 5 seconds to the time. And the final version could be upwards of 5000 cells.
So my question can the second line be altered to included the cell formatting (mainly font colour) while still staying fast.
Ideally I would like to be able to copy the cell values to a array/list along with the font formatting so I can do further sorting and operations on them before I "paste" them back on to the worksheet..
So my ideal solution would be some thing like
for x = 0 to 5000
array(x) = Sheets(sheet_).Cells(x, 1) 'including formatting
next
for x = 0 to 5000
Sheets("Output").Cells(x, 1)
next
is it possible to use RTF strings in VBA or is that only possible in vb.net, etc.
Answer*
Just to see how my origianl method and new method compar, here are the results or before and after
New code = 65msec
Sheets("Output").Cells(startrow, 2) = Sheets(sheet_).Cells(x, 1)
Sheets("Output").Range("B" & startrow).Font.ColorIndex = Sheets(sheet_).Range("A" & x).Font.ColorIndex 'copy font colour as well
Old code = 1296msec
'Sheets("Output").Cells(startrow, 2).Value = Sheets(sheet_).Cells(x, 1)
'Sheets(sheet_).Cells(x, 1).Copy
'Sheets("Output").Cells(startrow, 2).PasteSpecial (xlPasteFormats)
'Application.CutCopyMode = False
You could have simply used Range("x1").value(11)
something like below:
Sheets("Output").Range("$A$1:$A$500").value(11) = Sheets(sheet_).Range("$A$1:$A$500").value(11)
range has default property "Value" plus value can have 3 optional orguments 10,11,12.
11 is what you need to tansfer both value and formats. It doesn't use clipboard so it is faster.- Durgesh
For me, you can't. But if that suits your needs, you could have speed and formatting by copying the whole range at once, instead of looping:
range("B2:B5002").Copy Destination:=Sheets("Output").Cells(startrow, 2)
And, by the way, you can build a custom range string, like Range("B2:B4, B6, B11:B18")
edit: if your source is "sparse", can't you just format the destination at once when the copy is finished ?
Remember that when you write:
MyArray = Range("A1:A5000")
you are really writing
MyArray = Range("A1:A5000").Value
You can also use names:
MyArray = Names("MyWSTable").RefersToRange.Value
But Value is not the only property of Range. I have used:
MyArray = Range("A1:A5000").NumberFormat
I doubt
MyArray = Range("A1:A5000").Font
would work but I would expect
MyArray = Range("A1:A5000").Font.Bold
to work.
I do not know what formats you want to copy so you will have to try.
However, I must add that when you copy and paste a large range, it is not as much slower than doing it via an array as we all thought.
Post Edit information
Having posted the above I tried by own advice. My experiments with copying Font.Color and Font.Bold to an array have failed.
Of the following statements, the second would fail with a type mismatch:
ValueArray = .Range("A1:T5000").Value
ColourArray = .Range("A1:T5000").Font.Color
ValueArray must be of type variant. I tried both variant and long for ColourArray without success.
I filled ColourArray with values and tried the following statement:
.Range("A1:T5000").Font.Color = ColourArray
The entire range would be coloured according to the first element of ColourArray and then Excel looped consuming about 45% of the processor time until I terminated it with the Task Manager.
There is a time penalty associated with switching between worksheets but recent questions about macro duration have caused everyone to review our belief that working via arrays was substantially quicker.
I constructed an experiment that broadly reflects your requirement. I filled worksheet Time1 with 5000 rows of 20 cells which were selectively formatted as: bold, italic, underline, subscript, bordered, red, green, blue, brown, yellow and gray-80%.
With version 1, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" using copy.
With version 2, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the value and the colour via an array.
With version 3, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the formula and the colour via an array.
Version 1 took an average of 12.43 seconds, version 2 took an average of 1.47 seconds while version 3 took an average of 1.83 seconds. Version 1 copied formulae and all formatting, version 2 copied values and colour while version 3 copied formulae and colour. With versions 1 and 2 you could add bold and italic, say, and still have some time in hand. However, I am not sure it would be worth the bother given that copying 21,300 values only takes 12 seconds.

The User type definition must be placed before any subroutine in the module. The code works through the source worksheet copying values or formulae and colours to the next element of the array. Once selection has been completed, it copies the collected information to the destination worksheet. This avoids switching between worksheets more than is essential.

Just use the NumberFormat property after the Value property:
In this example the Ranges are defined using variables called ColLetter and SheetRow and this comes from a for-next loop using the integer i, but they might be ordinary defined ranges of course.
TransferSheet.Range(ColLetter & SheetRow).Value = Range(ColLetter & i).Value
TransferSheet.Range(ColLetter & SheetRow).NumberFormat = Range(ColLetter & i).NumberFormat
Does:
Set Sheets("Output").Range("$A$1:$A$500") = Sheets(sheet_).Range("$A$1:$A$500")
...work? (I don't have Excel in front of me, so can't test.)

I'm trying to CopyPicture cells in Column B, and name them the value in Column 1. I have code that works, except it keeps giving the pictures the wrong names. The baffling thing is that sometimes it works perfectly, and other times it does not.
I have tried to cobble together a routine based on posted examples of the CopyPicture command. I'm pasting it in below.
Yes, I'm a newbie at VBScript. Be gentle. ;-)
Sub makepic()
Dim path As String
path = "C:\BP\BP2020\JPGs\"
Dim CLen As Integer
Dim cntr As Integer
cntr = 1
Dim rgExp As Range
Dim CCntr As String
CString2 = "A1:A6"
Set rgExp2 = Range(CString2)
CString = "B1:B6"
Set rgExp = Range(CString)
For I = 1 To rgExp.Cells.Count Step 1
CCntr = rgExp2.Cells(I).Value
rgExp.Cells.Cells(I).Font.Size = 72
rgExp.Cells.Cells(I).CopyPicture Appearance:=xlScreen, Format:=xlBitmap
rgExp.Cells.Cells(I).Font.Size = 14
''' Create an empty chart with exact size of range copied
CLen = Len(rgExp.Cells.Cells(I).Value)
CWidth = CLen * 85
With ActiveSheet.ChartObjects.Add(Left:=1600, Top:=rgExp.Top, _
Width:=CWidth, Height:=50)
.Name = "ChartVolumeMetricsDevEXPORT"
.Activate
End With
''' Paste into chart area, export to file, delete chart.
If CCntr <> "" Then
ActiveChart.Paste
Selection.Name = "pastedPic"
ActiveSheet.ChartObjects("ChartVolumeMetricsDevEXPORT").Chart.Export (path + CCntr & ".jpg")
ActiveSheet.ChartObjects("ChartVolumeMetricsDevEXPORT").Delete
End If
cntr = cntr + 1
Next
End Sub
Again, I expect -- for example -- a picture of the contents of cell B1 to have the name of the contents of A1. I tried making the range A1:B4 (for example), but that got me 8 pictures. I finally decided to try to make 2 ranges, but that didn't work either.
I've got a series of .csv files that I'm importing, which contain color information I need to apply to the imported data. The color column is colon-delimited, and the data is pipe-delimited:
:::::65535::|ADAM 14-22TGH|CHERRY|twu|Diesel Fuel (RIG)|Fuel||
::::14994616:::|MARCO 41-12G|CRYSTAL|HVA|Diesel Fuel (RIG)|Rig Fuel|gal us|
:::65535:65535:65535:65535:|MARCO 41-12G|CRYSTAL|||||
The excel sheet contains defined colors for various data states (missing data, wrong data, too high, too low, etc.), so I loop through the imported data building a cell union, which I eventually apply colorization to:
Dim ds As Worksheet
Dim i As Long, j As Long, k As Long
Dim iUsedCol As Long, iUsedRow As Long, clrRequired As Long, color as Long
Dim rngRequired As Range
Dim colorMap As Variant
Dim colors() As String
clrRequired = CLng(GetSetting("Failed Required Field Check"))
' Get the values of the color column
iusedRow = ds.UsedRange.Rows.Count
colorMap = Range(ds.Cells(1, 1), Cells(iUsedRow, 1)).Value
' Delete the color map column
ds.Columns(1).EntireColumn.Delete
' Skip the first two rows
For i = 3 To iusedRow
colors = Split(colorMap(i, 1), ":")
' Offset by one column since we're deleting column 1 after
For j = 2 To UBound(colors) + 1
If colors(j - 1) = "" Then
Else
color = CLng(colors(j - 1))
' Required
If color = clrRequired Then
If rngRequired Is Nothing Then
Set rngRequired = ds.Cells(i, j)
Else
Set rngRequired = Application.Union(rngRequired, ds.Cells(i, j))
End If
End If
End If
Next j
Next i
' Set the colors
If Not rngRequired Is Nothing Then
rngRequired.Interior.color = clrRequired
End If
For simplicity I removed the three other identical checks for the other colors, but this is the pattern. Depending on the data this can be 50 rows or 12000 rows, with varying columns based on what is being checked. I have a report that takes over 20 minutes to run, and when I remove this coloring code it finishes in about 10 seconds.
Additionally here is what I am disabling while running the code:
Calculations
CancelKey
PrintCommunication
ScreenUpdating
Events
StatusBar
Alerts
Try the following code:
Dim ds As Worksheet
Dim i As Long, j As Long, k As Long
Dim iUsedCol As Long, iUsedRow As Long, clrRequired As Long, color As Long
'...
'Set ds = .....
'...
iUsedRow = ds.UsedRange.Rows.Count
' Skip the first two rows
For i = 3 To iUsedRow
colors = Split(ds.Cells(i, 1).Value, ":")
' Offset by one column since we're deleting column 1 after
For j = 2 To UBound(colors) + 1
If colors(j - 1) <> "" Then
ds.Cells(i, j).Interior.color = CLng(colors(j - 1))
End If
Next j
Next i
' Delete the color map column
ds.Columns(1).EntireColumn.Delete
That will process all colours in one loop. (That may be a problem if you are only trying to set certain colours, as defined by your GetSetting calls. If so, you may need to include an If statement to avoid processing if the colour specified isn't one of the colours you want to deal with.)
I am writing a VBA code that goes through a defined matrix size and filling cells randomly within its limits.
I got the code here from a user on stackoverflow, but after testing it I realized that it does not fit for avoiding duplicate filling, and for instance when filling 5 cells, I could only see 4 cells filled, meaning that the random filling worked on a previously filled cell.
This is the code I'm working with:
Dim lRandom As Long
Dim sCells As String
Dim sRandom As String
Dim rMolecules As Range
Dim i As Integer, j As Integer
Dim lArea As Long
lArea = 400 '20x20
'Populate string of cells that make up the container so they can be chosen at random
For i = 1 To 20
For j = 1 To 20
sCells = sCells & "|" & Cells(i, j).Address
Next j
Next i
sCells = sCells & "|"
'Color the molecules at random
For i = 1 To WorksheetFunction.Min(5, lArea)
Randomize
lRandom = Int(Rnd() * 400) + 1
sRandom = Split(sCells, "|")(lRandom)
Select Case (i = 1)
Case True: Set rMolecules = Range(sRandom)
Case Else: Set rMolecules = Union(rMolecules, Range(Split(sCells, "|")(lRandom)))
End Select
sCells = Replace(sCells, "|" & sRandom & "|", "|")
lArea = lArea - 1
Next i
rMolecules.Interior.ColorIndex = 5
Using this same exact code which works perfectly, WHAT can I insert and WHERE do I do that so that the code would check if a cell is previously already filled with a string or a color?
I feel as though this code I'm looking for should be right before
rMolecules.Interior.ColorIndex = 5
But I'm not sure what to type.
EDIT
From the comments I realized that I should be more specific.
I am trying to randomly fill cells with the blue color (.ColorIndex = 5), but what I need to check first is if the randomizing hadn't marked a cell twice, so that for instance in this case, if I want to mark 5 different cells, it marks only 4 of them because of a duplicate and thus fills only 4 cells with the blue color. I need to avoid that and make it choose another cell to mark/fill.
I'd appreciate your help.
Keep the cells you use in a Collection and remove them as you fill the random cells:
Sub FillRandomCells(targetRange As Range, numberOfCells As Long)
' populate collection of unique cells
Dim c As Range
Dim targetCells As New Collection
' make sure arguments make sense
If numberOfCells > targetRange.Cells.Count Then
Err.Raise vbObjectError, "FillRandomCells()", _
"Number of cells to be changed can not exceed number of cells in range"
End If
For Each c In targetRange.Cells
targetCells.Add c
Next
' now pick random 5
Dim i As Long, randomIndex As Long
Dim upperbound As Long
Dim lowerbound As Long
For i = 1 To numberOfCells
lowerbound = 1 ' collections start with 1
upperbound = targetCells.Count ' changes as we are removing cells we used
randomIndex = Int((upperbound - lowerbound + 1) * Rnd + lowerbound)
Set c = targetCells(randomIndex)
targetCells.Remove randomIndex ' remove so we don't use it again!
c.Interior.Color = 5 ' do what you need to do here
Next
End Sub
Sub testFillRandomCells()
FillRandomCells ActiveSheet.[a1:t20], 5
FillRandomCells ActiveSheet.[b25:f30], 3
End Sub
EDIT: Changed to make the target range and number of changed cells configurable as arguments to a function. Also added error checking (always do that!).
Why not build a list of random numbers and place in a Scripting.Dictionary, one can use the Dictionary's Exist method to detect duplicates, loop through until you have enough then you can enter your colouring code confident that you have a unique list.
I have a large data set which I need to manipulate and create individual worksheets. Within column B all cells which are coloured Green I would like to make a new worksheet for. Please see screen shot.
For example I would like to create worksheets titled "Shopping" & "Retail". Once the worksheet is created, I would then like to copy all the data between the "worksheet title" (Green Cells) from columns ("B:C") & ("AI:BH") Please see screen shot below for expected output;
The code I have so far is below as you can see it is not complete as I do not know how I would go about extracting data between the "Green Cells".
Sub wrksheetadd()
Dim r As Range
Dim i As Long
Dim LR As Long
Worksheets("RING Phased").Select
LR = Range("B65536").End(xlUp).Row
Set r = Range("B12:B" & (LR))
For i = r.Rows.Count To 1 Step -1
With r.Cells(i, 1)
If .DisplayFormat.Interior.ColorIndex = 35 Then
MsgBox i
Worksheets.Add(After:=Worksheets(Worksheets.Count)).Name = Cells (i,1).Value
Worksheets("RING Phased").Select
End If
End With
Next i
End Sub
Any help around this would be much appreciated.
Sorry for taking a while to get back to this, I've been somewhat busy the last few days, so I haven't had much time to be on StackOverflow.
Anyway, the way I'd go about this would be to store all the found values in an array, and then loop through that array in order to find the distance between them.
The following code works for me, using some very simplified data, but I think the principle is sound:
Option Explicit
Option Base 0
Sub wrksheetadd()
Dim r As Range, c As Range
Dim i As Long: i = 0
Dim cells_with_color() As Range: ReDim cells_with_color(1)
With Worksheets("RING Phased")
' Since it doesn't seem like the first cell you want to copy from is colored, hardcode that location here.
' This also saves us from having to test if the array is empty later.
Set cells_with_color(i) = .Range("B12")
i = i + 1
Set r = Range(.Range("B13"), .Range("B" & .Cells.Rows.Count).End(xlUp))
' Put all the cells with color in the defined range into the array
For Each c In r
If c.DisplayFormat.Interior.ColorIndex = 35 Then
If i > UBound(cells_with_color) Then
ReDim Preserve cells_with_color(UBound(cells_with_color) + 1)
End If
Set cells_with_color(i) = c
i = i + 1
End If
Next
' Loop through the array, and copy from the previous range value to the current one into a new worksheet
' Reset counter first, we start at 1, since the first range-value (0 in the array) is just the start of where we started checking from
' (Hmm, reusing variables may be bad practice >_>)
i = 1
While i <= UBound(cells_with_color)
Worksheets.Add(After:=Worksheets(Worksheets.Count)).Name = cells_with_color(i).Value
' Set the range to copy - we could just do this in the copy-statement, but hopefully this makes it slightly easier to read
Set r = .Rows(CStr(cells_with_color(i - 1).Row) + 1 & ":" & CStr(cells_with_color(i).Row))
' Change the destination to whereever you want it on the new sheet. I think it has to be in column one, though, since we copy entire rows.
' If you want to refine it a bit, just change whatever you set r to in the previous statement.
r.Copy Destination:=Worksheets(CStr(cells_with_color(i).Value)).Range("A1")
i = i + 1
Wend
End With
End Sub
It probably lacks some error-checking which ought to be in there, but I'll leave that as an exercise to you to figure out. I believe it is functional. Good luck!
I have a database that has in excess on 200,000 rows. When I was writing a VBA script I had a database of about 20,000 rows in mind so I didn't care whether the database was filtered or not because the VBA script ran quickly. So given the realization that the database is huge and testing the VBA script I was surprised to notice how slowly it ran. So without further to say this is how my code looks like :
Set wsDB = ThisWorkbook.Sheets("DB")
Dim nameIndex As Long: nameIndex = Application.Match(name, wsDB.Rows(1), 0)
Dim formula As String
formula = "=IFERROR(AVERAGEIFS(" + GRA(nameIndex) + "," + GRA(dateIndex) + ",R2C," + GRA(cellNameIndex) + ",RC1" + "),"""")"
where GRA is a function that returns the address of the range of a column.
Private Function GRA(ByRef rngIndex As Long)
GRA = "DB!" + CStr(Range(Cells(2, rngIndex), Cells(rowNos, rngIndex)).Address(1, 1, xlR1C1, 0, 0))
End Function
So given that I now filter the table beforehand how can I adjust my code so that it ignores all the hidden rows and takes into account only what is visible. Of course I am aware that a simple dirty solution would be to simply copy the filter database and paste it in a new sheet but that will affect the performance which is what I'm trying to improve.
You can use the following function to return a range of only visible cells.
Function VisibleCells(Rng As Range) As Variant
Dim R As Range
Dim Arr() As Integer
Dim RNdx As Long
Dim CNdx As Long
If Rng.Areas.Count > 1 Then
VisibleCells = CVErr(xlErrRef)
Exit Function
End If
ReDim Arr(1 To Rng.Rows.Count, 1 To Rng.Columns.Count)
For RNdx = 1 To Rng.Rows.Count
For CNdx = 1 To Rng.Columns.Count
Set R = Rng(RNdx, CNdx)
If (R.EntireRow.Hidden = True) Or _
(R.EntireColumn.Hidden = True) Then
Arr(RNdx, CNdx) = 0
Else
Arr(RNdx, CNdx) = 1
End If
Next CNdx
Next RNdx
VisibleCells = Arr
End Function
The above code came from http://www.cpearson.com/excel/VisibleCells.aspx.
Normally I would only post code that I write however this does exactly what I was thinking.
