How to get task hours in resources usage view in ms project by VBA?

I want to get one of these values (108,10,21...) from resources usage and do some operations on it in VBA macro (for exemple add a number to it and put it in another cell ) but i don't know how , I tried to learn by record macro but it didn't work. I hope my question is clear if not just ask for clarify and I will do it .

What you are asking for is the work at the assignment level, by resource. For example:

Sub GetAssignmentWorkByResource()

    Dim r As Resource
    For Each r In ActiveProject.Resources
        Dim a As Assignment
        For Each a In r.Assignments
            Debug.Print r.Name, a.Task.Name, a.Work / 60 & " h"
        Next a
    Next r
    
End Sub
