ParamArray must be declared as an array of Variant

  • Artikkeli

Each argument to a ParamArray parameter can be of a different data type. Therefore, the parameter itself must be declared as an array of Variant type. You can also supply any number of arguments to a ParamArray. When the call is made, each argument supplied in the call becomes a corresponding element of the Variant array. For example:

Sub MySub(ParamArray VarArg()) 
    . . . 
End Sub 
Call MySub ("First arg", 2, 3.54)

This error has the following causes and solutions:

  • In the definition of the procedure, the ParamArray parameter is defined as an array of a type other than Variant.

    Redeclare the parameter type as an array of Variant elements.

  • No data type was specified for the ParamArray parameter, but the procedure definition is within the scope of a Deftype statement, so the parameter is implicitly declared as having a type other than Variant. Use an explicit As Variant clause in the specification of the ParamArray parameter.
