You can't mix the two exception types. Under the covers, C++ exceptions use SEH and your SEH exception handler could mess up the exception propogation logic. As a result, the C++ compiler won't allow you to mix them.

PS: Structured Exception Handling is almost always a VERY bad idea. Internally Microsoft has banned the use of SEH except in very limited circumstances. Any component that does use structured exception handling is automatically subject to intense code reviews (we have tools that scan code looking for its use to ensure that no cases are missed).

The problem with SEH is that it's extremely easy to accidentally introduce security vulnerabilities when using SEH.
