Hi,



I'm trying to write a component in C++ that will take a variable number of 

(string) arguments and returns an encoded version of the string (a bit 

like using a ParamArray in VB)



However I have been unable to find any examples on how to do this. Can 

anyone point me in the right direction, or give any examples?



Thanks....



The code I have is



IDL:

[vararg, id(20), helpstring("method EncodeArgs")]

   HRESULT EncodeArgs([in] SAFEARRAY(VARIANT) *args,

   [out, retval] BSTR* pbstrEncoded);



header file:

	STDMETHOD(EncodeArgs)(/*[in]*/ SAFEARRAY *args,

/* [out, retval] */);

What about like this.......

 IDL:

 [vararg, id(20), helpstring("method EncodeArgs")]

    HRESULT EncodeArgs([in] VARIANT *args,

    [out, retval] BSTR* pbstrEncoded);

 

 header file:

 	STDMETHOD(EncodeArgs)(/*[in]*/ VARIANT *args,



Then

code like this

- first check if the 'args' parameter is array like this : args->vt == 

VT_ARRAY

- then retrieve array pointer like this : psa = args->parray;

(psa :SafeArray pointer)

- then access the data in the SafeArray using SafeArrayAccessData
