如何在（windows）tagVARIANT中存储字符串？

Question

How do you stock a string in a tagVARIANT without loosing (allocating) memory?

I'm using Microsoft SDK.

Answer 1

Use _variant_t which has the according assignment operators. If you have a VARIANT you can attach and detach it to the helper class.

Answer 2

something like this:

_bstr_t bstrVal(yourstring);
VARIANT varString;
varString.vt = VT_BSTR;
varString.bstrVal = bstrVal;

I have not compiled it so there may be compilation errors, but you get the idea.
