API constant masks

Suppose you have a DWORD type value that could be API_CONST1 or API_CONST2, or both.

Through VB, how do you handle the situation where its both, so "If value = API_CONST1 Then" would fail even though the value is API_CONST1 masked with the other constant?

Thanks.

If I understand your question I think this is the answer.

lValue contains the sum of APIConst1 and APIConst2.

Code:

---

If (lValue And APIConst1) = APIConst1 Then

End if

I think that it's -- I was trying to do the same, but on the wrong side of the equal sign :eek:

Thank you.
