add-in for the debugger

[schaereran gmx net]

Hy, i really need help in this addin, i just dont get it!:(( What i want to do: an addin for the VC++ debugger, which, when i (while debugging) rightclick on a variable appears in the context menue, and when i click my addin there, i want to calculate some things with the value of the variable. So my questions are:how do i bring my addin in the contextmenue, and how can i gain access to the value of the variable (on which i rightclicked) in the debugged code ? any advice?? thanx a lot andreas
