macro - modification
 

Hi All
I have received the following macro from Greg Wilson. I copies down a range
into respective month sheet and date column based on date (C2). I created
the month sheets manually.
What i need is the macro should check whether the month sheet is created or
not. If it is not, create month sheet and copy else copy the range.


Sub k()
Dim r As Range
Dim m As Integer, d As Integer
Dim msg As String, ttl As String
Dim sheetnames As Variant

sheetnames = Array("Jan", "Feb", "Mar", "Apr", "May", _
"Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")

With Sheets("Data")
With .Range("C2")
If Not IsDate(.Value) Then
msg = "Error: Date not entered in cell C2"
ttl = "Student Attendance"
MsgBox msg, vbCritical, ttl
Exit Sub
End If
m = Month(.Value)
d = Day(.Value)
End With
Set r = .Range(.Cells(3, 5), .Cells(3, 5).End(xlDown))
End With
With Sheets(sheetnames(m - 1)).Cells(3, d).Resize(r.Count)
..Value = r.Value
End With
Set r = Nothing
End Sub

With regards

Thank you Greg.
What actually I need is the macro has to create month sheet based on the
date in C2 not create all the month-sheets at a time.
If the sheet month.C2 is not exist then create and copy or just copy the data

yshridhar,

The code first checks to see if ALL the month sheets are there. It only
creates a sheet if it can't find it. The SheetExists function returns False
only if the sheet doesn't exist.
If Not SheetExists(nm) Then
Sheets.Add(After:=Sheets(Sheets.Count)).Name = sheetnames(i)
End If

I don't see any difference between creating them if they don't exist at the
beginning or creating them if/when it can't find them during the copy routine.

Yes Greg what you said is true. My idea is to create the sheet at the
begining of the month. Suppose 1/3/2008, march, if the sheet is not there
create sheet. Because I enter the attendance on datewise. So i thought the
file size won't increase as A and B columns in month sheet i enter IdNo,
Student Name.

Bob I learnt how to add new worksheet with a name from you suggestion.

Worksheets.Add(befo=Worksheets(Worksheets.Count )).Name = sheetnames(m - 1)

Just i have added this line to my original macro.
Now what i want is if the sheet is already exists it has to resume the copy
procedure.
I am not good at VB. Help me pls

I gave you that in essence. It creates the sheet if it doesn't exist, so
just add an Else and put the other code in there.

sheetnames = Array("Jan", "Feb", "Mar", "Apr", "May" etc...

As a side note, recent versions of Excel allow us to eliminate this array
with the function "MonthName"
This returns True.

Sub Demo()
Dim m
m = 3
Debug.Print MonthName(m, True) = "Mar"
End Sub
