Reply To: Using multiple custom functions

[Peter Seitz]

Hello,

I’m using a custom function for an analysis like in your example “CustomFunction.FPD”.

Now I’d like to implement a second custom function, so I was going to expand my code like the following example:

In Module -> AutoFunctions

    '   register the function
    With CustomFPScriptFunctions.Add("MyCustomFunction1")
        .Description = "Output Matrix"
        .Indeterministic = False
        
        With .Parameters.Add("Arg1")
            .Description = "First argument"
            .AllowedTypes = fpParameterTypeNumeric
        End With
    
        Set oMyFunction = New MyFunctionImplementationObject1
        
        .Register oMyFunction
    End With
    
        '   register the function
    With CustomFPScriptFunctions.Add("MyCustomFunction2")
        .Description = "Output Matrix"
        .Indeterministic = False
        
        With .Parameters.Add("Arg1")
            .Description = "First argument"
            .AllowedTypes = fpParameterTypeNumeric
        End With
    
        Set oMyFunction = New MyFunctionImplementationObject2
        
        .Register oMyFunction
    End With

And in my classmodule -> MyFunctionImplementationObject1

Option Explicit

Implements ICustomFPScriptFunctionCalculate1

Private Function ICustomFPScriptFunctionCalculate_Calculate1(SafeArrayOfArguments() As Variant)
    
ICustomFPScriptFunctionCalculate_Calculate = SafeArrayOfArguments()
    
End Function

And in my classmodule -> MyFunctionImplementationObject2

Option Explicit

Implements ICustomFPScriptFunctionCalculate2

Private Function ICustomFPScriptFunctionCalculate_Calculate2(SafeArrayOfArguments() As Variant)
    
ICustomFPScriptFunctionCalculate_Calculate = SafeArrayOfArguments()
    
End Function

But as soon as I add another function in my AutoFunctions neither of the two added functions is working. I get the error message “The referred function does not exist”

Can you tell me what I’m doing wrong ?
