Calculating attachment size in tigger

Hi,

 

i am trying to limit the attachment size to 2 MB through a trigger.it seems like not calculating correct size. i want to limit the users so that they only able to upload files less than 2 MB in size. 

 

i am trying with following code

 

trigger trgCheckFileSize on Attachment (after insert) {


list<Attachment> att = new List<Attachment>();   

for (Attachment a : Trigger.new) {         att.add(a);        }   

 

integer sizecheck = att.get(0).body.size();   

if (sizecheck  > 2097152){   

att.get(0).addError('max size 1 Mb: you are trying file size ' + String.Valueof(sizecheck));        }    

}

 

any idea why its not calculating the correct size.

ps: for file size 8kb, i am getting body size 8098.

 

thanks,

ok guys, i have figured out what was wrong.

 

instead of using (after insert)  i used (before insert)   and it worked.

 

well done Me...
