Invalid use of AddressOf operator

  • Article

The AddressOf operator modifies an argument to pass the address of a function rather than passing the result of the function call. This error has the following cause and solution:

  • You tried to use AddressOf with the name of a class method. Only the names of Visual Basic procedures in a .bas module can be modified with AddressOf. You can't specify a class method.

  • The procedure name modified by AddressOf is defined in a module in a different project.

  • You tried to modify the name of a DLL function or a function defined in a type library with AddressOf.

  • DLL and type library functions can't be modified with AddressOf. The procedure definition must be in a module in the current project. Move the definition to a module in this project or include its current module in the project.
