this simple question. have code: currentrow = 3 mycolumn = 2 currentcell = (currentrow & "," & mycolumn) workingsheet.cells(currentcell).value = (clientname & " " & "(" & clientlocation & ")" & " " & extradefinition) i thought place data on 'workingsheet' in position "b3" places data in cell "af1". why this? thanks, josh cell not expected used using it; have input row , column indices (as integers) separated comma. right code is: workingsheet.cells(currentrow, mycolumn).value = (clientname & " " & "(" & clientlocation & ")" & " " & extradefinition) another alternative have using range . example: workingsheet.range("b3").value = (clientname & " " & "(" & clientlocation & ")" & " " & extradefinition)

i've given assignment setup appfabric 2nd level caching using nhibernate appfabric cache provider (by simon taylor ). i've setup , it's working. in failure scenario, if cache cluster or whole service stops working (assuming have 1 cache server) application requests don't forward database. when restart cluster, application works intented. so, despite having 1 cache server isn't practically right, should make application use db in such failure cases? any suggestions appreciated.

i started learn python week ago , want write small programm converts email image (.png) can shared on forums without risking lots of spam mails. it seems python standard libary doesn't contain module can i`ve found out there's pil module (pil.imagedraw). my problem can't seem working. so questions are: how draw text onto image. how create blank (white) image is there way without creating file can show in gui before saving it? thanks :) current code: import image import imagedraw import imagefont def getsize(txt, font): testimg = image.new('rgb', (1, 1)) testdraw = imagedraw.draw(testimg) return testdraw.textsize(txt, font) if __name__ == '__main__': fontname = "arial.ttf" fontsize = 11 text = "example@gmail.com" colortext = "black" coloroutline = "red" colorbackground = "white" font = imagefont.truetype(fontname, fontsize) width, heigh...

so fastest way split word 2 bytes ? short s = 0x3210; char c1 = s >> 8; char c2 = s & 0x00ff; versus short s = 0x3210; char c1 = s >> 8; char c2 = (s << 8) >> 8; edit how about short s = 0x3210; char* c = (char*)&s; // c1 = c[0] , c2 = c[1] let compiler work you. use union , bytes split without hand made bit-shifts. @ pseudo code: union u { short s; // or use int16_t more specific // vs. struct byte { char c1, c2; // or use int8_t more specific } byte; }; usage simple: u u; u.s = 0x3210; std::cout << u.byte.c1 << " , " << u.byte.c2; the concept simple, afterwards can overload operators make more fancy if want. important note depending on compiler order of c1 , c2 may differ, known before compilation. can set conditinal macros make sure order according needs in compiler.

i have jmeter-client on local windows-based machine , jmeter-server on ubuntu-based machine in amazon aws. it works well. can generate load , results in csv-files on local machine. have little problem. when use it, can`t see response data server in csv files , in view result tree. see response code - it's 200 ok, see latency, response time etc. when try test local machine, without jmeter-server, looks good, , can see response data. can please me? since jmeter 2.9: distributed testing uses mode_stripped_batch, returns samples in batch mode (every 100 samples or every minute default). note mode_stripped_batch strips response data sampleresult, if need change mode (mode property in jmeter.properties) usually full responses not useful during load test , impact negatively performances of jmeter, sure need them

consider following js: $('#main').on('click', '.button', function); and corresponding html: <div id="main"> <span class="button">button</span> </div> this works fine far. when element class button clicked, child of main element, function called. unfortunately when viewed iphone, every tap on main element, causes flicker once. i found out can avoided not binding click event #main, entire $(document). i haven't found issue online far. know going on , if there nicer solution binding every click element document? * { -webkit-tap-highlight-color: transparent; } adding css solve problem.

i have following code (int k=0; k<maxthreads; k++) { int firstpart = k * tasksperthread; int secondpart = ((k+1) * tasksperthread) - 1; system.out.println(firstpart + "," + secondpart); } where maxthreads inputted user , tasksperthread 10/maxthreads. maxthreads never less 1. outputs pairs of numbers. example, if maxthreads = 2 (making tasksperthread = 5) outputs 0,4 5,9 covering ten values 0-9 i want ten values covered if maxthreads = 4. right code outputs this 0,1 2,3 4,5 6,7 but cover 0-9. ideally output 0-2 3-5 6-7 8-9 or combination has maxthreads number of sets of numbers , covers 0-9. how can adjust loop this? thank you. it being rounded down think, try using ceiling.

today while searching piece of code google, came across 1 q/a blog, been said can declare local variable inside method of class final. however, author reluctant enough explain need/ benefit of doing so. like public class { private void show() { final string s="checking"; } } i seek java gurus' educate me on this. in advance kind support , guidance. best regards! in addition other answers, making variable final enables use of variable in inline implementation of classes , interfaces: final string test = "test"; foo = new foo() { public void bar() { system.out.println(test); } }; edit: if beginner might worth pointing out variable in fact reference instance . when make variable final in fact making reference constant, is, final variable can never refer other instance after initialization. makes no claims whether actual referenced instance constant. for example, if final string[] foo = { "ba...

for reason, have google maps application attempting run, gives me grey screen , +/- options map. i've used 2 guides extensively, , continue have same problem. i've googled extensively, , seems issue must api console or dependencies, , i've included screenshots of those: must noted storing these files in folder syncs dropbox - don't know if that's bad thing or not. when export android application, i'm using keystore made, , alias made. doing because trying run on phone opposed emulator (because i've heard play isn't working emulators). i'm extracting so: and finally, here's console: here's manifest: <uses-sdk android:minsdkversion="13" android:targetsdkversion="17" /> <permission android:name="com.hotspotprime.permission.maps_receive" android:protectionlevel="signature" /> <uses-permission android:name="com.hotspotprime.pe...

in vimscript, need count of buffers considered listed/listable (i.e. buffers not have unlisted, 'u', attribute). what's recommended way of deriving value? you use bufnr() number of last buffer, create list 1 number , filter removing unlisted buffers, using buflisted() function test expression. " 'possible' buffers may exist let b_all = range(1, bufnr('$')) " unlisted ones let b_unl = filter(b_all, 'buflisted(v:val)') " number of unlisted ones let b_num = len(b_unl) " or... @ once let b_num = len(filter(range(1, bufnr('$')), 'buflisted(v:val)'))

i've got c++ application running on busybox (kernel 3.0.35 arm) listens multicast packets. seemed working fine until discovered if start app network cable unplugged , plug in later won't received multicast packets. can't figure out why. there no error, setting operations (bind, setsockopt, ...) finish successfully, ip maddr shows correct information well. select() won't report incoming data. there kernel differently if link not up? interestingly same app sends multicast packets on different addresses , doesn't seem affected link status, it's happily transmitting once plug cable in. any ideas? thanks, tom presumably issue join when startup. if cable isn't plugged in, igmp join request can't go anywhere, router doesn't know send multicasts you.
