How to find changelists submitted in the last week for a particular user using Perforce?

Answer 1

the p4 changes doesn't work in this case when we use p4api.net :

p4 changes file.c@2010/05/01,2010/06/01 

miss a blank between file.c and @ so cm1.addArg is not working in this case because it add a space and it will not be executed
