Application.RegisteredFunctions property (Excel)

Returns information about functions in either dynamic-link libraries (DLLs) or code resources that were registered with the REGISTER or REGISTER.ID macro functions. Read-only Variant.


expression.RegisteredFunctions (Index1, Index2)

expression A variable that represents an Application object.


Name Required/Optional Data type Description
Index1 Optional Variant The name of the DLL or code resource.
Index2 Optional Variant The name of the function.


If you don't specify the index arguments, this property returns an array that contains a list of all registered functions. Each row in the array contains information about a single function, as shown in the following table.

Column Contents
1 The name of the DLL or code resource.
2 The name of the procedure in the DLL or code resource.
3 Strings specifying the data types of the return values, and the number and data types of the arguments.

If there are no registered functions, this property returns null.


This example creates a list of registered functions, placing one registered function in each row on Sheet1. Column A contains the full path and file name of the DLL or code resource, column B contains the function name, and column C contains the argument data type code.

theArray = Application.RegisteredFunctions 
If IsNull(theArray) Then 
 MsgBox "No registered functions" 
 For i = LBound(theArray) To UBound(theArray) 
 For j = 1 To 3 
 Worksheets("Sheet1").Cells(i, j). _ 
 Formula = theArray(i, j) 
 Next j 
 Next i 
End If
