ReadCallBack problem

Thu Jul 16, 2009 12:20 pm

I am using cf3.5 with bluetools for a pocketpc.
I recieve data when connected in readcallback and try to switch the incoming data to different places (textboxes) using a public integer ('recdat')set outside readcallback by a click function (which also calls bwrite)to store the incoming buffer ('str'-also public) by calling functions selected by recdat (if recdat = n then function()).
Is there a problem with setting the incoming data as 'public' and is there a problem calling outside functions from with readcallback or is readcallback similar to a 'background worker' function and does not allow external functions being called?
Previously I opened other forms from Form1 and only recieved data into 1 textbox in each form but this is not really satisfactory.

Should be okay as long as you make sure that everything is synchronized. You can't modify a GUI-element in any callbacks without synchronization.
