warning C4238 : cast reference in void*

Hi,

I want to pass a reference of an object as the parameter of a function.
This function takes an void*

void foo(void* param)
{
...
}

int main()
{
CString szWord;

foo((void*) &szWord); //give C4238 warning : nonstandard extension
used : class rvalue used as lvalue
}

How can I solve this warning ?

Regards,
Eric
