Please Excuse My Inexperience,
I'm to write a function that returns the last row that returns a non empty string in collumn 1 using a do loop.
If there is no empty rows, you could simply go with something like this :
Public Sub MySub()
Dim wsTarget As Worksheet
Set wsTarget = ActiveSheet
Dim n As Integer
n = 1
Do While (wsTarget.Cells(n +1, 1).Value <> "")
n = n + 1
Loop
n = n - 1
'n now contains the line number of the last non-empty row.
End Sub
Edit : For this example, I suppose you're looking into the first column, and that the data starts on line 2. If there is no rows with data, n will be worth 1.

I'm working on a project and need at the moment to find the first empty cell just after text cells in a row in Excel. To clarify, let me explain to you what I'm lookng for with this screenshot
I want to write a code to return for me for like an example in the case of the 20th row the number of column of the cell E20 even if the first empty cell is A20 but like I said, i want the first empty cell juste after the last "not empty" one.
for the 21th row the result will be C21, the 22th row it will be F22 and there you go
Here's the code I wrote but for some reason it doesn't work, please help.
Function emptyCell(ws As Worksheet, ligne As Integer)
Dim m, p, n As Integer
Dim suite(700) As Integer
For k = 0 To 700
suite(k) = 0
Next
emptyCell = 0
i = 1
Do Until suite(i) = 0 And suite(i - 1) = 1
If ws.Cells(ligne, i) <> "" Then
suite(i) = 1
End If
i = i + 1
emptyCell = emptyCell + 1
Loop
End Function
Sub test()
Dim d As Integer
empty_cell = emptyCell(Sheets("tmp"), 2)
MsgBox (empty_cell)
End Sub
The logic of my code is to assign 0 for empty cells and 1 in the other caase, run a test to find the first 1-0 that's gonna appear in my array and get the column order from the order of this "1"
I know I'm not that clear cause I didnt want it to make it a long post and english is not my first language.
Thanks in advance
All if you want to get the first empty cell after the last non empty cell, why not try it like this?
Function emptyCell(ws As Worksheet, Row As Long) As Range
Set emptyCell = ws.Cells(Row, ws.Columns.Count).End(xlToLeft).Offset(, 1)
End Function
Sub Test()
Dim empty_cell As Range
Set empty_cell = emptyCell(Sheets("tmp"), 20)
MsgBox empty_cell.Address
End Sub
I have a data of some binary numbers in few range of cells, from A2 to A8, B2 to B8, and so on, till G column.
Now, I want to check the largest binary number from the above Rows and paste it to the cell, two row below the last used range. (i.e., Largest binary number from Row A to be paste in A10, and so on).
I am not finding any function which can find the value of binary numbers, and the code which I ran finds out the max number considering those as natural numbers.
Your help will be appreciated.
Thank You!
Okay first i made a function that converts binary to decimal and stored in a module. (You can store it wherever you want) This function handles any size binary
Function BinToDecConverter(BinaryString As String) As Variant
Dim i As Integer
For i = 0 To Len(BinaryString) - 1
BinToDecConverter = CDec(BinToDecConverter) + Val(Mid(BinaryString, Len(BinaryString) - i, 1)) * 2 ^ i
Next
End Function
Afterwards i made the sub that loops through all binarys on sheet1 (Might need to change this for your sheet)
Sub FindLargestBinary()
On Error Resume Next
Dim wb As Workbook
Dim ws As Worksheet
Set wb = Application.ThisWorkbook
Set ws = wb.Sheets("Sheet1")
Dim tempVal, tempRow As Integer
Dim iCoulmn, iRow As Integer
For iCoulmn = 1 To 7 'Run from A to G
tempRow = 2
tempVal = 0
For iRow = 2 To 8 'Run from row 2 to 8
If BinToDecConverter(ws.Cells(iRow, iCoulmn).Value) > tempVal Then tempVal = BinToDecConverter(ws.Cells(iRow, iCoulmn).Value): tempRow = iRow ' Check if current binary i higher then any previous
Next iRow
ws.Cells(iRow + 1, iCoulmn).Value = ws.Cells(tempRow, iCoulmn).Value 'Print highest binary
Next iCoulmn
End Sub
Hope this helps you out..
You can use the excel function Bin2Dec to change them into decimal
Function MaxBin(r as range)
Dim curmax as long
Dim s as range
For each s in r
If Application.WorksheetFunction.Bin2Dec(s.Text) > curmax Then curmax = Application.WorksheetFunction.Bin2Dec(s.Text)
Next s
MaxBin = curmax
End Function
Assuming your binary values are text strings this formula converts the values to numbers, finds the MAX and then converts back to a text string
=TEXT(MAX(A2:A8+0),"00000")
confirmed with CTRL+SHIFT+ENTER
or you can use this version which finds the max using AGGREGATE function and doesn't require "array entry"
=DEC2BIN(AGGREGATE(14,6,BIN2DEC(A2:A8+0),1))
I am not familiar with using macro's, but I think that what I would like excel to perform is best handled with a macro. So I can use all the input you may have!
I have these headers;
ID Tag Pen Sex Weight Class Inside range
With 450 rows of data. Based on the distribution of the weight data, I have in two other columns (class and number) the number of rows I want to select within each class. The selected rows must have the value "Yes" in the column "Inside range".
I want to randomly select the rows, based on the number needed for each class, and copy these rows to a new sheet. It sums up to 30 rows in the new sheet.
I hope you have a suggestion how to complete this action!
can you try the following, you will need to add a reference to Microsoft Scripting Runtime library:
Const rowCount = 450
Public Sub copyRows()
Dim i As Integer
Dim j As Integer
Dim classes As Scripting.Dictionary
Dim source As Worksheet
Dim colNumber As Integer
Dim colClassName as Integer
Dim colInsideRange As Integer
Dim allSelected As Boolean
Dim randomRow as Integer
Dim sumRemaining as Integer
allSelected = False
Set source = Worksheets("YourWorksheetName")
colClassName = 6 'this is the column number where class names are entered. I am assuming 6
colNumber = 7 'this is the column number where number of rows to be selected are entered. I am assuming 7
colInsideRange = 8 'this is the column number where "Inside Range" values are entered. I am assuming 9
For i = 2 to rowCount + 1 'assuming you have a header row
classes(CStr(source.Cells(i, colClassName))) = CInt(source.cells(i, colNumber)
Next i
Do until allSelected
Randomize
randomRow = Int ((Rnd * 450) + 2) 'assuming you have a header row, + 1 if you don't
If classes(CStr(source.Cells(randomRow, colClassName))) = 0 Then
With classes
sumRemaining = 0
For j = 1 to .Count - 1
sumRemaining = sumRemaining + .Items(j)
If sumRemaining > 0 Then Exit For
Next j
allSelected = (sumRemaining = 0)
End With
Else
source.Cells(randomRow, colInsideRange) = "Yes"
classes(CStr(source.Cells(randomRow, colClassName))) = classes(CStr(source.Cells(randomRow, colClassName))) - 1
End If
Loop
'Enter your code to copy rows with "Inside Range" = "Yes"
End Sub
Sorry if there are some errors or typos, I wrote from my mobile phone.
If I have a loop that commences:
For each c in Range("A1:C8")
Is there a property of the placeholder c (c.count, c.value, c.something,...) that identifies the number of times the loop has iterated thus far? I would rather use something like this than including another variable.
Instead of using a "for each c in range" you can do something like this:
Dim c as Long 'presumably you did this as a Range, just change it to Long.
Dim myRange as Range 'Use a range variable which will be easier to call on later
Set myRange = Range("A1:C8")
For c = 1 to myRange.Cells.Count
'Do something to the cell, identify it as myRange.Cells(c), for example:
myRange.Cells(c).Font.Bold = True '<--- replace with your code that affects the cell
Next
This allows you to do the exact same For/Next loop, without including an unnecessary counter variable. In this case, c is a counter but also serves the purpose of identifying the cell being impacted by the code.
You need to count it yourself like this
Dim i as integer
i = 0
For each c in Range("A1:C8")
i = i + 1
Or
Dim i as integer
Dim c as Range
For i = 0 to Range("A1:C8").Count - 1
Set c = Range("A1:C8").Cells(i)
(Revised)
Using Column or Row properties, as appropriate to the direction you are iterating, you can compute an ordinal number on the fly. Thus
For Each c1 in myRange
myOrdinal = c1.row - myRange.row + 1 ' down contiguous cells in one column
myOrdinal = c1.Column - myRange.Column + 1 ' contiguous columns, L2R

I have a two dimensional table in Excel. eg.
outputproduct blending combination
**5 P1:0.6/P3:0.5**
2 P1:0.3/P2:0.7
4 P5:0.4/P2:0.7
7 P11:0.7/P7:0.4
Suppose the range of the table varies from B2:C6 (it can vary). I have to create a function, whose first job is to read this range( which would be a user defined input) and then stores the data into a 2 dimensional array such that I could use the data(integer) in the first column and the string in the second column, appropriately.
The first column is the resultant product index, while the second column is the blending products in the given ratio, which combine together to give the product in the first column.
Then there is another table:
product index current stock updated stock
**1** **10**
2 20
**3** **50**
4 15
**5** **100**
. .
. .
. .
I have to update the stock amount in this table after the data processing.
For example, on combination of product 1 with product 3 in the ratio of 6:5 (units), 1 unit of product 5 is produced. So, I have to update the amount of stock for each of the products in table 2.
Any suggestions, how to convert the range into a 2 dimensional array?
Public Function Blending_function( R1 as Range, R2 as Range)
' R2 is the range of table 2, where the updating is to be done
' R1 is first stored in to a 2 dimensional array, such that the data in the
' column 1 could be read, and the data in the column 2 could be read (of table 1).
' the integer in the column 1 of table 1 refers to the product index in table 2.
' P(i) stands for the ith product. In first row of table-1, P1 and P3 combine in the
' ratio of 6:5 to give P5. The current stock of each product is provide in table-2,
' whose range is R2(entire table 2).
' R1 is the range of table 1, from where the processing is to be done
End Function
The main hurdle for me is to convert the range R1 (Table-1) into a 2 dimensional array. And then look from that array, the index of the output product, and locate that product in table-2 for updating the stock level.
Here is an example on how to work with 2D array. The function will break up the blending combination and extract the values that you want so that you can use those.
Sub Sample()
Dim Rng1 As Range, Rng2 As Range
On Error Resume Next
Set Rng1 = Application.InputBox("Please select the Table1 Range", Type:=8)
On Error GoTo 0
If Rng1.Columns.Count <> 2 Then
MsgBox "Please select a range which is 2 columns wide"
Exit Sub
End If
On Error Resume Next
Set Rng2 = Application.InputBox("Please select the Table2 Range", Type:=8)
On Error GoTo 0
If Rng2.Columns.Count <> 3 Then
MsgBox "Please select a range which is 3 columns wide"
Exit Sub
End If
Blending_function Rng1, Rng2
End Sub
Public Function Blending_function(R1 As Range, R2 As Range)
Dim MyAr1 As Variant, MyAr2 As Variant
Dim i As Long
Dim blndCom As String, OutputPrd As String
Dim ArP1() As String, ArP2() As String, tmpAr() As String
MyAr1 = R1
For i = 2 To UBound(MyAr1, 1)
OutputPrd = MyAr1(i, 1)
blndCom = MyAr1(i, 2)
tmpAr = Split(blndCom, "/")
ArP1 = Split(tmpAr(0), ":")
ArP2 = Split(tmpAr(1), ":")
Debug.Print OutputPrd
Debug.Print Trim(ArP1(0))
Debug.Print ArP1(1)
Debug.Print ArP2(0)
Debug.Print ArP2(1)
Debug.Print "-------"
Next
End Function
SNAPSHOT
Once you have these values you can use .Find to search for the product index in the range R2 and then use .Offset to enter your formula.
I'm not sure if I understood the entire story, but this is what a function to return
a multidimensional array could look like:
Public Sub Main_Sub()
Dim vArray_R1() As Variant
Dim oRange As Range
Set oRange = ThisWorkbook.Sheets(1).Range("A1:B5")
vArray_R1 = Blending_function(oRange)
'You do the same for The second array.
set oRange = nothing
End Sub
Public Function Blending_function(R1 As Range)
Dim iRange_Cols As Integer
Dim iRange_Rows As Integer
iRange_Cols = R1.Columns.Count
iRange_Rows = R1.Rows.Count
'Set size of the array (an existing array would be cleared)
ReDim vArray(1 To iRange_Rows, 1 To iRange_Cols)
vArray = R1
Blending_function = vArray
End Function
A second option could be to declare the function to return a boolean and since arguments are standard sent byRef; you can declare the ranges and arrays in the main sub only, and convert them both at the same time in the function. I wouldn't choose for this option, because you wouldn't be able to re-use the function afterwards to convert other ranges into arrays.
Supplementary info:
This technique works both ways. You can afterwards define a range and do:
set oRange = vArray
This on the condition that the Range has the same size as the array.
row = 2
column = "B"
Do While Len(Range(column & row).Formula) > 0
' repeat until first empty cell in column 'column'(user input)
' read (column, row) and (column+1, row) value
Cells(row, column).Value
Cells(row, column+1).value
' store in Array
Loop
