get projectdirectory at designtime

[Michael Meier]

1. i have written a component that needs to read information from a file.

2. the project that uses the component gives the file to to component via
a property

3. problem is, that this property must not be an absolut path but a
relative one. at runtime this is no big problem, i expect the input file
to be relative to the starting .exe whose path i get via
Application.StartupPath.
but what about DesignTime? when i use my component in the designer it has
the read the file too and i want its path relatively to the project
directory. if i try to use Application.StartupPath i get the path to the
devenv.exe wich will not help. i cannot use an absolute path because the
project must be opened at different machines.

so the whole question is: how do i get the directory of the project
containing my component
