1. Line and Col Positioning
can anyone tell me why these 2 lines get the line and column index
correctlly sometmes with the richedit control i am using, and why it
doesn't get them correctlly, fo example if i start of at line 1, col 1
and start tapping the down arrow it increment correctly line 2, line 3
etc but when i turn around and start hitting the up arrow it takes
about 2 hits and then starts incrementing down, i cannot work out
whether this is due to the way the richedit handles {13,10} -
"\n","\r" , if so does anyone know the flags i should be initialising
it with :- code below
Line = sendMessage(code,EM_LINEFROMCHAR,-1,0)
Col = w32lo_word(sendMessage(code,EM_GETSEL,0,0)) -
sendMessage(code,EM_LINEINDEX,-1,0)
thanks

Are you issuing these messages on KeyDown or KeyUp? I would recommend
KeyUp as that happens after the RichEdit has moved the caret.

that makes alot of sense i was infact using multiple handlers ill show you :
setHandler(code,{w32HActivate,w32HChange,w32HGotFocus,w32HLostFocus,w32HKeyDown,w32HKeyPress,w32HClick},routine_id("statbarupdate"))
