If I don't set the InitialDirectory, it goes to the exe's directory - which is not what I want. It rememebers the last selected director...
I was thinking many times, now days that we have Linq and other CLR language-specific built-in search, sort and other capabilities over tables, collections and object, why not have the 'SQL Server' or rather call it 'CLR Server' (not only OOP Server but CLR 3.5) which will be a CLR (or COM) DLL that exposes the data allowing users linqin...

How do I tell the designer that my control has a fixed height? ...
