After a lot of hardship i have come up with workflow which does a very straight forward thing. it looks for an activity with a certain subject line. when it finds the activity in question, if the activity has not been cancelled, it cancels it after adding a note to it. i have done it for all the activity types. to avoid duplication i am just sticking with the first two (task and email). Since i'm copy-pasting, there is a chance that there will be unmatched parenthesis.

the question that pops up as soon as you come across to the code. that how the hell you come across to the activitytype (which i used in switch). i am damn sure there are lots of smart ways to find them. but i debugged and looked for the value. (silly me...)
