How to monitor memory usage for managed/unmanaged code

I have an application that is built in C# 开发者_如何转开发.NET. It uses excel as a presentation layer and unmanged C++ as a processing engine. Is there a tool I can use to check for memory leaks for each component?

AQTime will instrument both managed and unmanaged code. I have used it successfully to find memory leaks in managed/unmanaged project.
