Re: Newbie: TCHAR to BSTR conversion

The easiest way to convert between the two is to use a _bstr_t:

TCHAR buffer[MAX_PATH];
....
_bstr_t bstrResult = _bstr_t(buffer);

I couldn't import wshom.ocx, but this code below accomplishes the task
you're trying to do. You can get the MSScript control here:

Best of luck,
