I am working in VBA for Excel at the moment but am really only versed in Matlab. It's important for my work to stay in the memory of vba (not on the worksheets of excel) for time purposes.
What I need to do is make an array of sequential integers, say 4000 through 5000.
In matlab this is really easy, I would just do... i = 4000:5000, or i=4000:1:5000. With the 1 in the second case being my 'step.'
I was wondering what is the best way to achieve this result in vba?
Thanks
Without looping - Just seen Rory's same answer above after posting
Sub MakeArray()
Dim x As Long, y As Long, arr As Variant
x = 4000: y = 5000
arr = Evaluate("Row(" & x & ":" & y & ")")
'Show result
Sheets(1).Range("A1").Resize(y - x + 1) = arr
End Sub
The following is an example of creating and then displaying a set of sequential numbers:
Sub seqnum()
Dim firstnum As Long, secnum As Long
firstnum = 7
secnum = 23
ReDim ary(1 To secnum - firstnum + 1) As Long
For i = 1 To UBound(ary)
ary(i) = firstnum + (i - 1)
Next i
msg = ""
For i = 1 To UBound(ary)
msg = msg & i & vbTab & ary(i) & vbCrLf
Next i
MsgBox msg
End Sub
I Us "Fill" - "Series":
Write in first cell number ex. 400 and in the "Series" window insert increment step and in "Stop Value" last value. ex. 420
Or with Macro
Range("I1").Select
ActiveCell.FormulaR1C1 = "4000"
Range("I1").Select
Selection.DataSeries Rowcol:=xlColumns, Type:=xlLinear, Date:=xlDay, _
Step:=1, Stop:=4020, Trend:=False

Using Visual Studio Community 2017 And AdvancedHMI to create a PC based HMI application. I have several running with no issue so moving onto something new.
On each line I have 7 array's (500 real numbers each array) and would like to capture this data daily and save to Excel.
Using EPPlus and AdvancedHMI I have the following code.
Private Sub DataSubscriber1_DataChanged(sender As Object, e As Drivers.Common.PlcComEventArgs) Handles DataSubscriber1.DataChanged
If e.ErrorId = 0 AndAlso e.Values.Count > 0 AndAlso e.Values(0) = "True" Then
Console.WriteLine("About to read the data")
Dim MyValues() As String = EthernetIPforCLXCom1.Read("VCell_1A_FES_Cycle_Average[0]", 500)
Console.WriteLine(MyValues.Length & "elements read.")
'* Transfer the values to Excel
Using ExcelPackage As New OfficeOpenXml.ExcelPackage(New System.IO.FileInfo("c:\Data.xlsx"))
For I = 0 To MyValues.Length - 1
Console.WriteLine("Element " & I & "=" & MyValues(I))
ExcelPackage.Workbook.Worksheets(1).Cells(1, I + 1).Value = MyValues(I)
Next
End Using
End If
End Sub
Running this and triggering my tag vale to execute the datascriber I get the following.
About to read the data
500Elements read.
Element 0=87.945
Exception Thrown: 'System.IndexOutOfRangeException' in EPPlus.dll
Everything looks like it should work but I am very new to VB or any type of coding for that matter. My forte' is PLC ladder logic.
Thanks.
Here is what I have working. The Datascriber has a trigger tag in the PLC. Once it's triggered it collects the array data, all 500 elements. Creates a new Excel file and writes the data to Column A, Cells 1-500
Private Sub DataSubscriber1_DataChanged(sender As Object, e As Drivers.Common.PlcComEventArgs) Handles DataSubscriber1.DataChanged
If e.ErrorId = 0 AndAlso e.Values.Count > 0 AndAlso e.Values(0) = "True" Then
Console.WriteLine("About to read the data")
Dim MyValues() As String = EthernetIPforCLXCom1.Read("VCell_1A_FES_Cycle_Average[0]", 500)
Console.WriteLine(MyValues.Length & "elements read.")
Transfer the values to Excel
Using ExcelPackage As New OfficeOpenXml.ExcelPackage(New IO.FileInfo("C:\Data.xlsx"))
ExcelPackage.Workbook.Worksheets.Add("test")
For Index = 0 To MyValues.Length - 1
Console.WriteLine("Element " & Index & "=" & MyValues(Index))
Dim ws As OfficeOpenXml.ExcelWorksheet = ExcelPackage.Workbook.Worksheets(1)
Console.WriteLine("Worksheet OK")
Dim CellNum As String = "A" & (Index + 1)
ws.Cells(CellNum).Value = MyValues(Index)
Next
ExcelPackage.Save()
End Using
End If
End Sub
I am writing a macro that processes an excel with lots of data. One of the rows contains a date range like wkstartdate - wkenddate and I would like to use dateadd function to print next date range every week (like '27-01-14 - 02-02-14' in below case) but unable to do so.
'06-01-14 - 12-01-14'
'13-01-14 - 19-01-14'
'20-01-14 - 26-01-14'
I used below excerpt which fails:
Range("E" & Lastrow).Select
prwk = Split(ActiveCell.Value, "-")
'curr_wkstart = DateAdd("d", 7, prwk(1)) 'error as maybe prwk(1) isnt correct format
'curr_wkend = DateAdd("d", 7, prwk(2)) 'error
Range("E" & Lastrow + 1).Value = curr_wkstart & curr_wkend 'no result
For testing purpose I print, prwk(1) which is 20/01/14 in the above case, in a diff cell and add 7 days, which gives me 1/21/2020 instead of '27/01/14'. I also tried using Cdate function, but still error
Can you please advise??
I think what you want to use here are the Format and DateSerial functions. Here's how I came at it:
Function GetNextWeek(TheStartWeek)
a = Split(TheStartWeek, " - ")
b = Split(a(1), "-")
c = DateSerial(b(2), b(1), b(0)) + 1
d = c + 6
GetNextWeek = Format(c, "dd-mm-yy") & " - " & Format(d, "dd-mm-yy")
End Function
Sub Test()
Debug.Print GetNextWeek("13-01-14 - 19-01-14") 'Givs you "20-01-14 - 26-01-14"
End Sub
Hope this helps.
This macro works on line 5 ,so i need this macro to work on all lines in one sheet instead of one macro for each line. Row X and email range A:L are copy paste in all lines i.e.( X1 A1:L1 | X2 ,A2:L2 ...)
Dim X5 As Variant
Private Sub Worksheet_Change(ByVal Target As Range)
If Range("X5").Value = 1 And X5 <> 1 Then
ActiveSheet.Range("A5:L5").Select
ActiveWorkbook.EnvelopeVisible = True
With ActiveSheet.MailEnvelope
.Introduction = " send thru macro "
.Item.To = "email#gmail.com"
.Item.Subject = "ALERT"
.Item.Send
End With
End If
X5 = Range("X5").Value
End Sub
Not sure if you got your answer or not so I am attempting to answer this question.
To make it flexible for any row, you can store the row of the current cell in a variable using Target.Row and then simply use that to construct your range.
Also to understand how Worksheet_Change works, you may want to see THIS
Is this what you are trying?
Dim X5 As Variant
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo Whoa
'~~> Check if the chnage happened to multiple cells
If Target.cell.CountLarge > 1 Then Exit Sub
Dim Rw As Long
'~~> Get the row number of the cell that was changed
Rw = Target.Row
If Range("X" & Rw).Value = 1 And X5 <> 1 Then
Application.EnableEvents = False
Range("A" & Rw & ":L" & Rw).Select
ActiveWorkbook.EnvelopeVisible = True
With ActiveSheet.MailEnvelope
.Introduction = " send thru macro "
.Item.To = "email#gmail.com"
.Item.Subject = "ALERT"
.Item.Send
End With
End If
X5 = Range("X" & Rw).Value
Letscontinue:
Application.EnableEvents = True
Exit Sub
Whoa:
MsgBox Err.Description
Resume Letscontinue
End Sub
This one has me stumped. I am populating a Listbox with a range and then formatting column 4 as d/mm/yyyy. This works fine if all cells in column 4 have a date. As some cells that are populated into the Listbox are in fact blank the sub crashes when it hits these cells. I have tried various if and else statements to skip the activecell if blank with no luck.
Grateful for any assistance.

Sub populate_listbox_1()
Dim I As Long
Dim I2 As Long
Dim list_count As Long
Dim MyData As Range
Dim r As Long
With edit_report_input.compliments_listbox
.ColumnCount = 17
.ColumnWidths = "70;300;75;90;80;80;100;0;0;0;0;0;0;0;0;20;0"
.RowSource = ""
Set MyData = ActiveSheet.Range("A4:Q498") 'Adjust the range accordingly
.List = MyData.Cells.Value
For r = .ListCount - 1 To 0 Step -1
If .List(r, 1) = "" Then
.RemoveItem r
End If
Next r
End With
For I = 0 To edit_report_input.compliments_listbox.ListCount - 1
edit_report_input.compliments_listbox.List(I, 4) = Format(DateValue(edit_report_input.compliments_listbox.List(I, 4)), "d/mm/yyyy")
Next I
date_rec_compliment = Format(date_rec_compliment, "d/mm/yyyy")
End Sub
you can always check before changing the format. See if below snippet helps
For I = 0 To edit_report_input.compliments_listbox.ListCount - 1
if edit_report_input.compliments_listbox.List(I, 4) <> "" Then
edit_report_input.compliments_listbox.List(I, 4) = Format(DateValue(edit_report_input.compliments_listbox.List(I, 4)), "d/mm/yyyy")
End If
Next I
I'm trying to copy and paste a range, to create a 28 by 28 grid of numbers "rotating" the values so that each time the range is pasted into the next column, the range is moves down by one row and the last value "overflows" back to the top of the next row, I've got this far but am stumped on the overflow part (i' relative newbie to VBA)
Sub Test()
Dim oRange As Range
Set oRange = ActiveSheet.Range("A1:A28")
Dim i As Integer
For i = 1 To 28
oRange.Copy
oRange.Offset(i, i).PasteSpecial xlPasteAll
Next i
End Sub
Also I need to copy and paste values and formatting of the cells
Hope you guys can help
Thanks
Dan
Sub Test()
Dim oRange As Range
Dim startColumn As String
Dim rangeStart As Integer
Dim rangeEnd As Integer
Dim cellCount As Integer
Dim i As Integer
startColumn = "A"
rangeStart = 1
rangeEnd = 28
cellCount = rangeEnd - rangeStart + 1
For i = 1 To cellCount - 1
Set oRange = ActiveSheet.Range(startColumn & rangeStart & _
":" & startColumn & (rangeEnd - i))
oRange.Copy
oRange.Offset(i, i).PasteSpecial xlPasteAll
Set oRange = ActiveSheet.Range(startColumn & (rangeEnd - i + 1) & _
":" & startColumn & rangeEnd)
oRange.Copy
oRange.Offset((-1 * cellCount) + i, i).PasteSpecial xlPasteAll
Next i
End Sub
EDIT:
to insert a blanck row at index 'i':
Rows(i & ":" & i).Select
Selection.Insert Shift:=xlDown
to insert 5 rows at the top of the worksheet insert a row 5 times at index 1:
For i = 1 To 5
Rows("1:1").Select
Selection.Insert Shift:=xlDown
Next
