Disable save icon

[VBA FTW]

How do I disable the save icon in a workbook? I've tried this:

Sub DisableSaveButton
Application.CommandBars("Standard").FindControl(ID:=3).Enabled = False
End Sub

and assigned it to a button but to no avail. Any suggestions?

BETTER SOLUTION:

define a boolean variable, set to false on workbook open
on BeforeSave event, check if boolean is false, if so cancel save, exit procedure and tell user they must use a custom button to save the file

SaveFormButtonClicked as Boolean

Private Sub Workbook_Open()
SaveFormButtonClicked = False
End Sub

Sub SaveFormAsXLSX

ThisWorkbook.SaveFormButtonClicked = True
'save commands
ThisWorkbook.SaveFormButtonClicked = False
End Sub

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)

If SaveFormButtonClicked = False Then
    MsgBox "The save button you just clicked is disabled. Please use the 'Save Form' button on the right of the spreadsheet.", vbInformation, "Standard Saving Is Disabled"
    Cancel = True
    Exit Sub
End If

From my testing so far, going this route will disable the Save icon on ribbon, the Save menu item, the Save As menu item, and the Save keyboard shortcut.

...ok, so it doesn't actually disable these items, it prevents the user from being able to use them to save the file...basically forces them to use a control button you've placed on the sheet.

Still curious as to why the code in my OP doesn't work though
