Custom Function Category - Excel 4 Macro Sheet

The following code will add a custom category to the excel function wizard, and then assign all of my custom built functions to that category. The routine even solves a problem which microsoft states as having no solution.

However, it uses a test1 and test2 function in order to create the category and evaluate it's Category ID.

The problem is that I cannot seem to hide or delete the Test1 and Test2 functions once the custom category has been created. I do not want the Test1 and Test2 functions to be visible in the functions wizard.

I know that it is something to do with the fact that they were created in the Excel 4 macro sheet, but how do I stop them from showing.

And now the code.....

Sub AddFunctionToCategory()
Dim TheCategoryID As Integer
Dim TheNewCategory As String
Dim TheCurrentCategory As String

    TheNewCategory = "My New Category"
    Workbooks.Add
    Worksheets.Add Type:=xlExcel4MacroSheet
    'add a test function to create the new category
   
    ActiveWorkbook.Names.Add Name:="Test1", RefersTo:="sheet1!$a$1", _
        Category:=TheNewCategory, MacroType:=xlFunction
   
    'add a second function to the User Defined category
    ActiveWorkbook.Names.Add Name:="Test2", RefersTo:="sheet1!$a$1", _
        Category:="User Defined", MacroType:=xlFunction
    For i = 1 To 100
        'Set the category of function 2 to i and see if the
        'category name matches the new category
        TheCategoryID = i
        ActiveWorkbook.Application.MacroOptions Macro:="Test2", _
            Category:=TheCategoryID
        TheCurrentCategory = ActiveWorkbook.Application.Names("Test2").Category
        If TheCurrentCategory = TheNewCategory Then
            Exit For
        End If
    Next i
   
    ActiveWorkbook.Application.MacroOptions Macro:="MyFunction1", Category:=TheCategoryID
    ActiveWorkbook.Application.MacroOptions Macro:="MyFunction2", Category:=TheCategoryID

    ActiveWorkbook.Names("Test1").Visible = False      'or .Delete
    ActiveWorkbook.Names("Test2").Visible = False      'or .Delete
   
    ActiveWorkbook.Close (False)

End Sub

You need to use the .Item property of the .Names collection to delete a name.  Try this:



    ActiveWorkbook.Names.Item("Test1").Delete
    ActiveWorkbook.Names.Item("Test2").Delete

Hi Leedurrant,

I've tested your code, and the lines you posted/used seem to work correctly for me:

ActiveWorkbook.Names("Test1").Visible = False
ActiveWorkbook.Names("Test2").Visible = False

The behaviour is strange though, the delete seems to delete the names, but they remain in the Function Wizard Categories List. The Visible = False propery hides the names in my test.

I have tried both of these recommendations, but the problem still remains.

For your information, the code is called from the ThisWorkbook Workbook_Open of an xla file.

Do either of you have any other ideas that will resolve this problem?

Thanks

Hi Leedurrant,

I've put your code in the auto-open event of an xla file, and without any problem your original code works perfectly.

Afterwards I've tested this, works also, and maybe a solution:

Sub AddFunctionToCategory()
Dim TheCategoryID As Integer
Dim TheNewCategory As String
Dim TheCurrentCategory As String

    TheNewCategory = "My New Category"
    Workbooks.Add
    Worksheets.Add Type:=xlExcel4MacroSheet
    'add a test function to create the new category
     
    ActiveWorkbook.Names.Add Name:="MyFunction1", RefersTo:="sheet1!$a$1", _
        Category:=TheNewCategory, MacroType:=xlFunction
     
    'add a second function to the User Defined category
    ActiveWorkbook.Names.Add Name:="MyFunction2", RefersTo:="sheet1!$a$1", _
        Category:="User Defined", MacroType:=xlFunction
    For i = 1 To 100
        'Set the category of function 2 to i and see if the
        'category name matches the new category
        TheCategoryID = i
        ActiveWorkbook.Application.MacroOptions Macro:="MyFunction2", _
            Category:=TheCategoryID
        TheCurrentCategory = ActiveWorkbook.Application.Names("MyFunction2").Category
        If TheCurrentCategory = TheNewCategory Then
            Exit For
        End If
    Next i
     
    ActiveWorkbook.Close (False)
End Sub

In the Workbook open event I just placed this code:

Private Sub Workbook_Open()
AddFunctionToCategory
End Sub

Hope this helps

Sorry Calacuccia,

I did type out a comment, but it seems to have dissappeared.

Your previous suggestion is the way in which I am actually calling the macro at the moment.

The problem is still unsolved. I am not sure why it is that it doesn't delete/hide the functions for me.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

I suggest you delete this question and ask a new one to get new attention if the problem persists..

Calacuccia,

I resolved this problem about a month ago. Sorry, I didn't realize that the question was still outstanding.

FYI, I changed the function names and found that the Test1 and test2 names still appeared. From this I realized that the functions were actually kind of imbedded into the add-in file from when I didn't call the delete line.

I simply copied all of the coding into a new add-in and hey-presto it worked.

Thanks for your help on this one anyway

You can delete this question now as you have solved it yourself, or grade it for the persistence of me telling you it should have worked ;-)

Your call.

Go on then, I think you've helped me enough whilst I've been building this add-in.

Thanks again....

My Pleasure, LeeDurrant.

Hope to be able to help you again later, and allow me to learn from it, as I certainly did with your custom function categories.

Cheers !
