You may declare the Variant type of v1 explicitly:

v1.vt = VarTypes.VT_BOOL;

But i suppose that will lead to the next Exception: "COMException: A VT_VARIANT 
must be combined with VT_BYREF (base vartype 12)". Combining the Type with a 
VT_ARRAY and/or a VT_BYREF leads to "Unable to serialize variant" Exception 
again. I think the problem isn't specific to invoking the msmqMessage.Send 
method but to passing a variant array as an argument. It seems that there 
existst nor any documentation how to pass a variant array as an argument nor a 
working example for that: The example at 
http://discuss.develop.com/archives/wa.exe?A2=ind0307e&L=jawin&D=0&T=0&P=1722 
doesn't work for me. And the description at 
http://jawinproject.sourceforge.net/jawinuserguide_dispatch.html#dispatchptr_usage_methods_arrays
 isn't sufficient, at least for me.
