it’s easy determine rendered height of font using fontmetrics , other way around? how can obtain font fit specific height in pixels? "give me verdana in size 30 pixels high ascender descender." how ask java this? jen, i don't think there's "direct" way find font height; indirect way... looping through sizes, , testing height of each <= required height. if you're doing once, loop through them... if you've doing "on fly" binary search, it'll quicker. cheers. keith.

what wrong following code? task.start fails index out of range exception. more clear.. failing because value coming 3 in loop !!! actionprovider m1 = new actionprovider(); actionprovider m2 = new actionprovider(); actionprovider m3 = new actionprovider(); list<action> actions = new list<action>() { ()=> { m2.doit(); }, ()=> { m3.doit(); }, }; task t = new task(() => { m1.doit(); }); (int = 0; < actions.count; i++) { t.continuewith(t1 => actions[i]()); } t.start(); it because reuse same variable, i, several times. when execute task has been incremented. try change for-loop follows: (int = 0; < actions.count; i++) { var action = actions[i]; t.continuewith(t1 => action()); } the difference here create copy of variable pass continuewith.

i've got string coming in so: '202,203,204,205,226,230,274' i want break string down array of numbers , records ids. so far, have: string[] myarray = mystring.split(','); int[] myintarray = new int[myarray.length]; for(int x = 0; x < myarray.length; x++) { myintarray[x] = convert.toint32(myarray[x].tostring()); } model.records = db.records .where(q => q.recordid.contains(myintarray) .tolist(); it's complaining contains not working ints. confused contains does? thanks in advance! i think want do: .where(q => myintarray.contains(q.recorid)) the way have it, you're expecting recordid array (i'm assuming it's int ?), whereas think want take single recordid , see if it in array of int s.
