i have 2 datefield variables , subtract them , return difference number of months nearest month. how might this? thanks help! for definite answer using calendar month lengths: months = lambda a, b: abs((a.year - b.year) * 12 + a.month - b.month) example: >>> import datetime >>> = datetime.date(2011, 2, 8) >>> b = datetime.date(2010, 5, 14) >>> months(a, b) 9 edit, if want round based on days too: months = lambda a, b: abs((a.year - b.year) * 12 + a.month - b.month) + int(abs(a.day - b.day) > 15) example: >>> import datetime >>> = datetime.date(2011, 2, 8) >>> b = datetime.date(2010, 5, 14) >>> months(a, b) 9 >>> b = datetime.date(2010, 5, 30) >>> months(a, b) 10

connection.settransactionisolation(int) warns: note: if method called during transaction, result implementation-defined. this bring question: how begin transaction in jdbc? it's clear how end transaction, not how begin it. if connection starts inside in transaction, how supposed invoke connection.settransactionisolation(int) outside of transaction avoid implementation-specific behavior? answering own question: jdbc connections start out auto-commit mode enabled, each sql statement implicitly demarcated transaction. users wish execute multiple statements per transaction must turn auto-commit off . changing auto-commit mode triggers commit of current transaction (if 1 active). connection.settransactionisolation() may invoked anytime if auto-commit enabled. if auto-commit disabled, connection.settransactionisolation() may invoked before or after transaction. invoking in middle of transaction leads undefined behavior. sources: javadoc jdbc tut...

i wondering if possible draw core graphics in content view of scroll view because @ moment, in drawrect section of uiscrollview, draws on static view , when scroll content view, graphics stay still... (which means i'm not drawing in right view) do have create uiview subclass , draw there , add uiscrollview, while handling zooming , scrolling uiscrollview or - there way can keep in 1 subclass of uiscrollview! (i hope makes sense!) thanks! typically, don't draw in uiscrollview directly. uiscrollview container view scrolls 1 content view or several tile views. should add content view(s) addsubview: , position them needed. scroll view handle scrolling , zooming.

i have function returns non-void. on caller side, want detect whether return statement called in original function or not. i know, not allowed have non-void function return nothing , throw warning in gcc. want print runtime error based on whether return called or control reached end of function. the callee defined user. provide declaration. so, want ensure implementer of callee function, doesn't skip "return" statement. you can't determine how function returns caller (other whether throws exception or returns). thing can prevent function returning explicitly using compiler warning or put run-time error call @ end of function don't want have control fall off end of. 1 trick might able have return type function have default constructor gives run-time error; return statements need use other constructor. once that, though, might add error call end of function or change return type gcc warning.

when using javascript assign onclick handlers html <a> tags, have specific question when comes use of ajax - what's best way url ajax request? should use this.href or code handler function itself? consider following link: <a id="link" href="http://mysite.com/getdata.php">get data</a> then, javascript: document.getelementbyid('link').onclick = function() { // send ajax request } i using this.href inside handler i'm worried user clicks link before domready fires , links activated. better use href="javascript:void(0);" in html , construct url in handler itself? way, link nothing unless it's activated. what's best-practice here? thanks, brian think perspective: how page architecture hold if no js enabled? your application should responsive user input under circumstances, , should not rely on implicit assumptions whether users have javascript-enabled browsers. sounds ridiculous, ri...

i have gridview control contains image field. however, image url built several fields in returned dataset. how concatenate fields together, , @ point do can pass image url imagefield in gridview? guessing it's on rowdatabound don't know how access each of rows in dataset? thanks. i'm not sure trying concatenate without code example, perform concatenation before binding gridview , store in private member on class can access later in rowdatabound event. you can use row data bound event find control within row , set imageurl property. private string m_concaturl; protected void gridview_rowdatabound(object sender, gridviewroweventargs args) { if(args.row.rowtype == datacontrolrowtype.datarow) { image imgctrl = (image) args.row.findcontrol("imgctrl"); imgctrl.imageurl = m_concaturl; } }

i working on homework assignment requires selection occur pulls out element containing specific attribute of maximum value compared other records. i've read number of sources online reference "aggregate" relational algebra function called maximum, don't describe how works using basic operators. how 1 select attribute containing maximum value? you can express aggregate functions basic operators. it's pretty neat thing. suppose have table t, , we'd find maximum of "value" field. first, should take cartesian product of t -- or rather copy of itself, t2. select rows t.value smaller t2.value: nets unwanted rows, value less value of other row. maximal values, should subtract these unwanted rows set of rows. , that's it. @ least that's basic idea, need use projections dimensions right. unfortunately have no idea how insert latex here, using relational algebra notation, it'd this: π(t.a1...tan, t.value)(t) - π(t.a1...tan, ...

please tell me how protect our resource in apk package. simple rename-extract process, 1 can copy , thief application drawable resource images or soundfx files. question is, there way protect drawable resource in android application? the drawable needs accessible operating system, has readable. if want keep secure, consider storing encrypted raw asset, load it, decrypt bytestream , pass bitmapfactory. that, of course, has slight performance ramifications , force hand-code lot of stuff have done in xml otherwise. that aside, there many ways steal data - if it's drawable, people take screenshot.

for example, want create function can return number (negative, zero, or positive). however, based on exceptions, i'd function return boolean false is there way write function can return int or boolean ? ok, has received lot of responses. understand i'm approaching problem incorrectly , should throw sort of exception in method. better answer, i'm going provide example code. please don't make fun :) public class quad { public static void main (string[] args) { double a, b, c; a=1; b=-7; c=12; system.out.println("x = " + quadratic(a, b, c, 1)); // x = 4.0 system.out.println("x = " + quadratic(a, b, c, -1)); // x = 3.0 // "invalid" coefficients. let's throw exception here. how handle exception? a=4; b=4; c=16; system.out.println("x = " + quadratic(a, b, c, 1)); // x = nan system.out.println("x = " + quadratic(a, b, c, -1)); // x = nan } public static do...
