How to add Worksheets, after last active sheet, with InputBox? - excel

How can I implement "count" from the InputBox?
I encountered a syntax error with the below code.
Sub AddSheets_via_Input_Box()
Dim Prompt As String
Dim Caption As String
Dim DefValue As Long
Dim NumSheets As String
DefValue = 1
Prompt = "...how many people are working Fraud Today?"
Caption = "Tell me…"
NumSheets = InputBox(Prompt, Caption, DefValue)
Sheets.Add(After:=Temp,Count:=NumSheets)
End Sub
Problem starts at:
(After:=Temp,Count:=NumSheets)
It all works with :
Sheets.Add Count:=NumSheets
I need those new sheets added after two exiting sheets in that workbook.

As far as I can see you haven't declared Temp in your code (if it's a sheet's code name then you need to let us know that also).
Also you can't use parentheses like that in VBA, you only use them when you're grouping something, or evaluating something to return to the left hand side of an expression.
here's a tidied up version:
Sub AddSheets_via_Input_Box()
Dim numberOfSheets As Integer
'// Here we use parentheses because we are returning a value to numberOfSheets...
numberOfSheets = CInt(Trim$(InputBox("...how many people are working Fraud Today?", "Tell me…", 1)))
If IsNumeric(numberOfSheets) Then
With ActiveWorkbook
'// Here we DON'T use parentheses because we aren't returning or evaluating anything...
.Sheets.Add After:=.Sheets("Temp"), Count:= numberOfSheets
End With
Else
MsgBox "Invalid parameter supplied - use numbers only"
End If
End Sub

Why doesn't this simple VBA code work in Excel?

I'm quite new to programming with VBA (or any language, let's be honest). I'm trying to do a project for work, adding short sections at a time to see if the code still works, and trying out new code in a separate Sub. I've come across an error that I can't get around. The results don't change when they're the only line in a separate Sub.
The following code works:
ActiveWorkbook.Sheets("Template").Copy After:=ActiveWorkbook.Sheets("Student info")
Whereas the following code, when run, breaks with a 424 run-time error (object required). I've tried selecting instead of naming, still no luck. It does successfully copy the worksheet to the correct place, despite the error, but is called 'Template (2)'.
ActiveWorkbook.Sheets("Template").Copy(After:=ActiveWorkbook.Sheets("Student info")).name = "newname"
This is very confusing because the code below does work. Is it just that trying to name something after using 'add' does work, but after 'copy', it doesn't?
ActiveWorkbook.Sheets.Add(After:=ActiveWorkbook.Sheets("Student info")).name = Student_name
Thanks in advance for any help.
The reference (to the created copy) as return value (of a function) would be useful, but as Worksheet.Copy is a method of one worksheet (in opposite to Worksheets.Add what is a method of the worksheets-collection), they didn't created it. But as you know where you created it (before or after the worksheet you specified in arguments, if you did), you can get its reference by that position (before or after).
In a function returning the reference:
Public Enum WorkdheetInsertPosition
InsertAfter
InsertBefore
End Enum
Public Function CopyAndRenameWorksheet(ByRef sourceWs As Worksheet, ByRef targetPosWs As Worksheet, ByVal insertPos As WorkdheetInsertPosition, ByVal NewName As String) As Worksheet
'If isWsNameInUse(NewName) then 'Function isWsNameInUse needs to be created to check name!
'Debug.Print NewName & " alredy in use"
'Exit Function
'End If
With sourceWs
Dim n As Long
Select Case insertPos
Case InsertAfter
.Copy After:=targetPosWs
n = 1
Case InsertBefore
.Copy Before:=targetPosWs
n = -1
Case Else
'should not happen unless enum is extended
End Select
End With
Dim NewWorksheet As Worksheet
Set NewWorksheet = targetPosWs.Parent.Worksheets(targetPosWs.Index + n) 'Worksheet.Parent returns the Workbook reference to targetPosWs
NewWorksheet.Name = NewName ' if name already in use an error occurs, should be tested before
Set CopyWorksheetAndRename = NewWorksheet
End Function
usage (insert after):
Private Sub testCopyWorkSheet()
Debug.Print CopyAndRenameWorksheet(ActiveWorkbook.Sheets("Template"), ActiveWorkbook.Sheets("Student info"), InsertAfter, Student_name).Name
End Sub
to insert the copy before the target worksheet, change third argument to InsertBefore (enumeration of options).
New Worksheet.Name needs to be unique or you'll get an error (as long you not implemented the isWsNameInUse function to check that).
Also note that there is a difference between .Sheets and .Worksheets
You can get the links to the documentation by moving the cursor (with mouse left-click) in the code over the object/method you want more infos on and then press F1

Excel global variable reseted to empty when navigating through workbooks

I encounter a weird problem that I believe is related to Excel behavior, rather than to my code.
I have a global variable named "numEtape", which is an integer. My code consists in several steps where the user has to type data on a sheet, then press a button which saves the data in an array and increments the "numEtape", before going to the next step.
The code (simplified) looks like this :
Dim numEtape As Integer
Sub AjoutEssai()
numEtape = 2
UFPreAjoutInfos.Show 'Unrelated Userform that asks user for more informations, but doesn't modify "numEtape" or call any other macro
Call InterfaceFiller
End Sub
Sub InterfaceFiller()
Dim rangedubtn As Range
Dim btnPrecedent As Button
Select Case numEtape
Case 2
'Change value of some cells
Case 3
'Change value of some cells
Case 4
'Change value of some cells
Case Is >= 5
'Change value of some cells
Case Else
Debug.Print "Error"
End Select
Set rangedubtn = Sheets("Interface").Range("M3")
Set btnPrecedent = Sheets("Interface").Buttons.Add(rangedubtn.Left, rangedubtn.Top,rangedubtn.Width, rangedubtn.Height)
With btnPrecedent
.OnAction = "mSuivant"
.Caption = "Suivant"
.Name = "btnSuivant"
End With
End Sub
Sub mSuivant()
numEtape = numEtape + 1
Call InterfaceFiller
End Sub
I don't think the code itself is important, what I can expect from it, since I first call AjoutEssai(), is for numEtape to always be greater than 2.
However, when during the steps the user opens and close other excel/office files (that don't have any vba code/macros in it), excel seems to empty numEtape, which makes the Select Case go to the Case Else.
When does excel remove global variables from memory, and is there a way to prevent this behavior from happening?
Public numEtape As Long
A viable option is to use the word public like public numEtape As Long.
Then the variable will be saving its value for as long as the Excel workbook is opened. In older versions of VBA the word was Global (What is the difference between Dim, Global, Public, and Private as Modular Field Access Modifiers?)
Dim numEtape As Long
For using Dim outside of Sub or Function, the variable will be emptied, after the code is over. Take this snippet only:
Dim numEtape As Long
Sub MainTest()
numEtape = 23
End Sub
Once you run it and you hit End Sub the variable would be emptied as well. Check after running the MainTest():
Sub PrintingVariable()
Debug.Print numEtape
End Sub
If you want to save the value, there are 2 basic ways that work:
Write the value in an excel cell
Write the value in a database

Range.Find a value from a separate workbook not working - code check

tl;dr: Running a range.find function on a reference workbook doesn't seem to find text that's definitely there. Please critique my code.
My current goal is to have Textbox B of Userform automatically populated based on user input for Textbox A. I'm trying to make that work by automatically searching a reference workbook for the Textbox A (user input) string and returning a value from an offset cell.
I finally have the search running without vomiting an error at me, but it can't seem to find text that's clearly present. My code:
Function findSLINCalc(calc As String)
'Variables
Dim calcWkbk As Excel.Workbook
Dim slinCell As Excel.Range
Dim lCalc As Excel.Worksheet
Set calcWkbk = Excel.Workbooks("New COR Calculations.xlsx")
Set lCalc = calcWkbk.Sheets(1)
'Search the calculation spreadsheet for SLIN
If Not lCalc.Range("A1:A100").find(calc) Is Nothing Then
MsgBox "I found it!"
findSLINCalc = lCalc.Range("A1:A100").find(calc).Offset(1, 10).Value
Else
MsgBox "Nothing there!"
End If
End Function
Private Sub SLINTB_AfterUpdate()
findSLINCalc (Me.SLINTB.Value)
End Sub
I'm reasonably certain I'm calling the function incorrectly in my subroutine. Even so, running this code as is only gives me the "Nothing there!" message box. Surely it would give me the other one if it found something, right?
Other possibly pertinent info:
The reference workbook will vary in length but not format or file name/location.
The string I'm searching for will be part of a merged cell (columns A+B).
Thanks in advance!

Open MsgBox if a date on birthday list matches today

Every time I try and execute my code it says "object required."
I want a MsgBox to open if one a date on my birthday list matches today.
The birthday list extends from b2 to b100 and I want to look through to find the birthday.
This is a piece of code I took from a YouTube video.
The MsgBox pops up every time I open the workbook.
Private Sub Workbook_Open()
Dim cl As Range
Set cl = ThisWorbook.Sheets("Birthdays").Range("B2:B100")
If IsDate(cl) Then
If Now >= cl Then
MsgBox "Somebody's had a birthday!"
End If
End If
End Sub
You are getting Object Required error because of a typo ThisWorbook should be ThisWorkbook
It is very normal to encounter such errors. So always use Option Explicit. I have covered it in To ‘Err’ is Human
So Can I have it added to my code automatically?
Yes you can. To have it added to all new files you create, simply select "Tools" -> "Options" in the VBE, and tick the "Require Variable Declaration" box.
Note: This will effect only new files that you create. You will need to add it yourself to existing files.
I basically just want my excel to create a msgbox when I open it, if one of the date on my birthday list matches today.
You can use Application.WorksheetFunction.CountIf to check if there is today's date in a range.
Sub Sample()
Dim ws As Worksheet
Dim rng As Range
Dim matchFound As Long
Set ws = ThisWorkbook.Sheets("Birthdays")
Set rng = ws.Range("B2:B100")
matchFound = Application.WorksheetFunction.CountIf(rng, Date)
If matchFound > 0 Then
MsgBox "Birthday Found"
Else
MsgBox "Birthday Not Found"
End If
End Sub
Screenshot
cl is a Range object representing 99 dalmatians cells, each encapsulating a Variant value.
The IsDate function is happy to take a Variant, but doesn't know what to do with 99 of them.
Because Range has a hidden default property, you can use it as if it were a value - but, especially for someone that's just beginning to learn VBA, it makes for confusing, implicit, "magic" code that says one thing, and does another.
If IsDate(cl.Value) Then
The implicit Range.Value member call here, yields a Variant representing the cell's value itself if the range represents only a single cell, otherwise (i.e. if the range is for more than one cell) it yields a Variant pointing to a 2D Variant array (in this case 99x1) that's holding every single value.
IsDate wants one value, so if we have 99 of them, we need a loop. But here's the thing: the last thing we want to do is iterate individual cells, get their Value, and verify that - because that would be very slow.
So instead, we grab that 2D Variant array, and iterate that.
If cl.Count = 1 Then
'single-cell range: not a 2D array
If Now >= cl.Value Then
MsgBox "Somebody's had a birthday on " & Format(cl.Value, "yyyy-mm-dd")
End If
Exit Sub
End If
Dim values As Variant
values = cl.Value
Dim currentRow As Long
For currentRow = LBound(values, 1) To UBound(values, 1)
Dim currentCol As Long
For currentCol = LBound(values, 2) To UBound(values, 2)
Dim currentValue As Variant
currentValue = values(currentRow, currentCol)
If IsDate(currentValue) Then
If Now >= currentValue Then
MsgBox "Somebody's had a birthday on " & Format(currentValue, "yyyy-mm-dd")
Exit Sub
End If
End If
Next
Next
Right now the msgbox just pops up every time I open the excel whether a birthday matches or not.
Sounds like your actual code has On Error Resume Next somewhere - that makes VBA ignore any run-time errors and merrily keep running, ...and you definitely don't want that. Rule of thumb, never use On Error Resume Next to side-step an error. Execution is normally halted when there's an "object required" error: an unconditional MsgBox popping means execution is allowed to continue in an error state, and that can't be a good thing.
As Sid found out, the type mismatch is caused by a typo -- this shouldn't be allowed to happen: make sure every module you ever type any code in says Option Explicit at the top, and it'll never happen again... for your early-bound code (late-bound code is still vulnerable to typos, but that's another story for another time).
Lastly, note that several of the above mentioned issues would have been reported by Rubberduck's code inspections (disclaimer: I manage this open-source project) - including the typo, the implicit default member calls, and the absence of Option Explicit.

Modifying a spreadsheet using a VB macro

I have two spreadsheets... when one gets modified in a certain way I want to have a macro run that modifies the second in an appropriate manner. I've already isolated the event I need to act on (the modification of any cell in a particular column), I just can't seem to find any concrete information on accessing and modifying another spreadsheet (this spreadsheet is located on a different LAN share also... the user has access to both, though).
Any help would be great. References on how to do this or something similar are just as good as concrete code samples.
In Excel, you would likely just write code to open the other worksheet, modify it and then save the data.
See this tutorial for more info.
I'll have to edit my VBA later, so pretend this is pseudocode, but it should look something like:
Dim xl: Set xl = CreateObject("Excel.Application")
xl.Open "\\the\share\file.xls"
Dim ws: Set ws = xl.Worksheets(1)
ws.Cells(0,1).Value = "New Value"
ws.Save
xl.Quit constSilent
You can open a spreadsheet in a single line:
Workbooks.Open FileName:="\\the\share\file.xls"
and refer to it as the active workbook:
Range("A1").value = "New value"
After playing with this for a while, I found the Michael's pseudo-code was the closest, but here's how I did it:
Dim xl As Excel.Application
Set xl = CreateObject("Excel.Application")
xl.Workbooks.Open "\\owghome1\bennejm$\testing.xls"
xl.Sheets("Sheet1").Select
Then, manipulate the sheet... maybe like this:
xl.Cells(x, y).Value = "Some text"
When you're done, use these lines to finish up:
xl.Workbooks.Close
xl.Quit
If changes were made, the user will be prompted to save the file before it's closed. There might be a way to save automatically, but this way is actually better so I'm leaving it like it is.
Thanks for all the help!
Copy the following in your ThisWorkbook object to watch for specific changes. In this case when you increase a numeric value to another numeric value.
NB: you will have to replace Workbook-SheetChange and Workbook-SheetSelectionChange with an underscore. Ex: Workbook_SheetChange and Workbook_SheetSelectionChange the underscore gets escaped in Markdown code.
Option Explicit
Dim varPreviousValue As Variant ' required for IsThisMyChange() . This should be made more unique since it's in the global space.
Private Sub Workbook-SheetChange(ByVal Sh As Object, ByVal Target As Range)
' required for IsThisMyChange()
IsThisMyChange Sh, Target
End Sub
Private Sub Workbook-SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)
' This implements and awful way of accessing the previous value via a global.
' not pretty but required for IsThisMyChange()
varPreviousValue = Target.Cells(1, 1).Value ' NB: This is used so that if a Merged set of cells if referenced only the first cell is used
End Sub
Private Sub IsThisMyChange(Sh As Object, Target As Range)
Dim isMyChange As Boolean
Dim dblValue As Double
Dim dblPreviousValue As Double
isMyChange = False
' Simple catch all. If either number cant be expressed as doubles, then exit.
On Error GoTo ErrorHandler
dblValue = CDbl(Target.Value)
dblPreviousValue = CDbl(varPreviousValue)
On Error GoTo 0 ' This turns off "On Error" statements in VBA.
If dblValue > dblPreviousValue Then
isMyChange = True
End If
If isMyChange Then
MsgBox ("You've increased the value of " & Target.Address)
End If
' end of normal execution
Exit Sub
ErrorHandler:
' Do nothing much.
Exit Sub
End Sub
If you are wishing to change another workbook based on this, i'd think about checking to see if the workbook is already open first... or even better design a solution that can batch up all your changes and do them at once. Continuously changing another spreadsheet based on you listening to this one could be painful.
