I wrote a small .NET add in to excel 2007 that read data from external c++ api and display it inside an excel.
The task manager shows that I'm having a memory leak (the memory usage is inflate linearly up to 250MB after whitch it throws an "Excel cannot complete this task with available resources error") but the problem disappears as soon as I minimize the excel window.

The api uses delegates to return data and I update it into a dictionary. another thread is updating the excel from the dictionary every second.

It is unlikely that the unmanaged code is responsible of the leak.

Does anybody have an idea what can cause this?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
