The following code example shows how to create a custom menu with four menu options, each of which calls a macro.
Sample code provided by: Holy Macro! Books, Holy Macro! It's 2,500 Excel VBA Examples
The following code example sets up the custom menu when the workbook is opened, and deletes it when the workbook is closed.
“`vb Option Explicit
Private Sub Workbook_BeforeClose(Cancel As Boolean) With Application.CommandBars(“Worksheet Menu Bar”) On Error Resume Next .Controls(“&MyFunction”).Delete On Error GoTo 0 End With End Sub
Private Sub Workbook_Open() Dim objPopUp As CommandBarPopup Dim objBtn As CommandBarButton With Application.CommandBars(“Worksheet Menu Bar”) On Error Resume Next .Controls(“MyFunction”).Delete On Error GoTo 0 Set objPopUp = .Controls.Add( _ Type:=msoControlPopup, _ before:=.Controls.Count, _ temporary:=True) End With objPopUp.Caption = “&MyFunction” Set objBtn = objPopUp.Controls.Add With objBtn .Caption = “Formula Entry” .OnAction = “Cbm_Active_Formula” .Style = msoButtonCaption End With Set objBtn = objPopUp.Controls.Add With objBtn .Caption = “Value Entry” .OnAction = “Cbm_Active_Value” .Style = msoButtonCaption End With Set objBtn = objPopUp.Controls.Add With objBtn .Caption = “Formula Selection” .OnAction = “Cbm_Formula_Select” .Style = msoButtonCaption End With Set objBtn = objPopUp.Controls.Add With objBtn .Caption = “Value Selection” .OnAction = “Cbm_Value_Select” .Style = msoButtonCaption End With End Sub “`
The menu “MyFunction” is added when the workbook opens, and is deleted when the workbook closes. It provides four menu options, with a macro assigned to each option. The user-defined function (UDF) “MyFunction” multiplies three values in a range together and returns the result.
“vb
Function MyFunction(rng As Range) As Double
MyFunction = rng(1) rng(2) rng(3)
End Function
“
Formula Entry: This menu option is assigned the macro “Cbm_Active_Formula”, which calls the UDF named “MyFunction” that multiplies the numbers in the preceding 3 cells, and stores value of the UDF in the active cell. You must have values in the range B6:D6 and select cell E6 before clicking this menu option.
“`vb Sub Cbm_Active_Formula() ‘setting up the variables. Dim intLen As Integer, strRng As String
‘Using the active cell, E6. With ActiveCell ‘Check to see if the preceding offset has valid data, and if there are three values If IsEmpty(.Offset(0, -1)) Or .Column < 4 Then
‘If the data is not valid, call MyFunction directly as a formula, but with no parameters. .Formula = “=MyFunction()” Application.SendKeys “{ENTER}” Else
‘If the data is valid, create a range of the preceding 3 cells strRng = Range(Cells(.Row, .Column – 3), _ Cells(.Row, .Column – 1)).Address intLen = Len(strRng)
‘Call MyFunction as a formula, with the range as the parameter. .Formula = “=MyFunction(” & strRng & “)” Application.SendKeys “{ENTER}” End If End With End Sub “`
Value Entry: This menu option is assigned the macro “Cbm_Active_Value”, which enters the value produced by the UDF named “MyFunction” into the active cell. You must have values in the range B6:D6 and select cell E6 before clicking this menu option.
“`vb Sub Cbm_Active_Value() ‘Set up the variables. Dim intLen As Integer, strRng As String
‘Using the active cell, E6. With ActiveCell ‘If there isn’t enough room in the column, then send a warning. If .Column < 4 Then Beep MsgBox "The function can be used only starting from column D!"
‘Otherwise, call MyFunction, using the range of the previous 3 cells. Else ActiveCell.Value = MyFunction(Range(ActiveCell.Offset(0, -3), _ ActiveCell.Offset(0, -1))) End If End With End Sub “`
Formula Selection: This menu option is assigned the macro “Cbm_Formula_Select”, which uses an InputBox for the user to select the range which the UDF “MyFunction” should calculate. The return value of the UDF is stored in the active cell.
“`vb Sub Cbm_Formula_Select() ‘Set up the variables. Dim rng As Range
‘Use the InputBox dialog to set the range for MyFunction, with some simple error handling. Set rng = Application.InputBox(“Range:”, Type:=8) If rng.Cells.Count <> 3 Then MsgBox “Length, width and height are needed -” & _ vbLf & “please select three cells!” Exit Sub End If ‘Call MyFunction in the active cell, E6. ActiveCell.Formula = “=MyFunction(” & rng.Address & “)” End Sub “`
Value Selection: This menu option is assigned the macro “Cbm_Value_Select”, which uses an InputBox for the user select the range which the UDF “MyFunction” should calculate. The value is stored in the active cell directly, instead of being returned by the UDF.
“`vb Sub Cbm_Value_Select() ‘Set up the variables. Dim rng As Range
‘Use the InputBox dialog to set the range for MyFunction, with some simple error handling. Set rng = Application.InputBox(“Range:”, Type:=8) If rng.Cells.Count <> 3 Then MsgBox “Length, width and height are needed -” & _ vbLf & “please select three cells!” Exit Sub End If
‘Call MyFunction by value using the active cell, E6. ActiveCell.Value = MyFunction(rng) End Sub “`
