How to run vbscript from C++ code?

Hi all,
How to vb script from a C++ code.

the script is like:

Function execute()
execute = obj.xml 'obj.xml is a xml
End Function

the script is working fine if i write it in a vbs file and double click on it.
but how to call it from a C++ code.

I tried with IScriptControl::Run but the its not giving any output.

SAFEARRAYBOUND rgsabound[] = { 0, 0 }; // 0 elements, 0-based

psa = SafeArrayCreate(VT_VARIANT, 1, rgsabound);
if (!psa)

_variant_t outpar = m_pScriptControl->(m_bstrFunction, &psa);
// _bstrFunction = execute

but after execution of this statement outpar is empty.

Can you not use a system call?

Expand|Select|Wrap|Line Numbers
  1. system("myfile.vbs");

I havent tried with system().
i was using the same code previously but at that time i was creating xml by concatnation of values like
resultset = resultset & "<row "
resultset = resultset & value
resultset = resultset & "/>
and then
execute = resultset

at that time the function IScriptControl::Run() gives me what i was expecting. but now i changed the script which generate the xml directly using a COM dll (the dll is registered) but now Run() is failing.
Again if i write the same script in file with message box to display the xml and run it by double clicking it, i can see the results on messagebox means there is no problem with the new xml generator object. it is doing his job. but dont know why Run() is failing?
