FORMULA TO REVERSE DIGITS IN A CELL

I explored a lot on internet for a customized formula which can reverse the digits in a cell and found many solutions using VBA user defined function or by installing add-in but couldn't find any help with excel formula. So here is the formula for it that I developed after 3 hours of struggle:)

=SUMPRODUCT(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)*1,POWER(10,ROW(INDIRECT("1:"&LEN(A1)))-1)) 

Please post in comment section if you have some other short and simple way to do it.

Thanks!

MAKE NEXT CONTROL VISIBLE ONCE THE FOCUS LOSES FROM FIRST CONTROL (KEYDOWN EVENT)

Below is the code to make next textbox visible once you finish typing in first textbox and press enter key or tab.

Controls on my form:

4 labels:                     lblCode, lblName, lblDept and lblDesig

4 textboxes:               txtCode, txtName, txtDept and txtDesig

1 CommandButton:   cmdSubmit

First I have made all the controls invisible except first textbox and label (lblcode & txtcode in my case) while loading the userform.

Private Sub UserForm_Initialize()

Me.txtCode.SetFocus

Me.txtName.Visible = False

Me.txtDept.Visible = False

Me.txtDesig.Visible = False

Me.lblName.Visible = False

Me.lblDept.Visible = False

Me.lblDesig.Visible = False

Me.cmdSubmit.Visible = False

End Sub

Only the first textbox and label will be visible when userform loads.

Below code on KeyDown Event of txtCode will make next set of controls (lblName & txtName) visible when you press enter key or tab key after typing in first textbox (txtCode) and set the focus on txtName.

Private Sub txtCode_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)

If KeyCode = vbKeyReturn Or KeyCode = vbKeyTab Then

        If txtCode.Text <> vbNullString Then

            txtName.Visible = True

            lblName.Visible = True

            txtName.SetFocus

        End If

End If

End Sub

Below code on KeyDown Event of txtName will make next set of controls (lblDept & txtDept) visible when you press enter key or tab key after typing in second textbox (txtName) and set the focus on txtDept.

Private Sub txtName_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
If KeyCode = vbKeyReturn Or KeyCode = vbKeyTab Then
    If txtName <> vbNullString Then
        txtDept.Visible = True
        lblDept.Visible = True
        txtDept.SetFocus
    End If
End If
End Sub

Below code on KeyDown Event of txtDept will make next set of controls (lblDesig & txtDesig) visible when you press enter key or tab key after typing in third textbox (txtDept) and set the focus on txtDesig.

Private Sub txtDept_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)

If KeyCode = vbKeyReturn Or KeyCode = vbKeyTab Then

    If txtDept <> vbNullString Then

        txtDesig.Visible = True

        lblDesig.Visible = True

        txtDesig.SetFocus

    End If

End If

End Sub

Below code on KeyDown Event of txtDesig will make next control (cmdSubmit) visible when you press enter key or tab key after typing in last textbox (txtDesig) and set the focus on cmdSubmit.

Private Sub txtDesig_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)

If KeyCode = vbKeyReturn Or KeyCode = vbKeyTab Then

    If txtDesig <> vbNullString Then

        cmdSubmit.Visible = True

        cmdSubmit.SetFocus

    End If

End If

End Sub

vbKeyReturn - Enter key on your keyboard

vbKeyTab - Tab key on your keyboard

CALCULATE TOTAL NUMBER OF A WEEKDAY IN A MONTH

Cell D2 : Data validation for Month Name
Cell E2: Data validation for Weekday Name

Formula in F2:
=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(DATE(YEAR(D2),MONTH(D2),1)&":"&EOMONTH(D2,0))))=MATCH(E2,{"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"},0)))

Note: Make sure the month name list (A2:A13 in my case) that you are using for data validation, is in date format, not in text format.
