i have been trying row number effectively. fails data cleared , cells not explicitly deleted. i guess because of "used range". what did using epplus using (var excel = new excelpackage(hpf.inputstream)) { var ws = excel.workbook.worksheets["sheet1"]; if(ws.dimension.end.row > 2003) { var result = new jsonresult(); result.data = "filelimitexceeded" ; but gives me incorrect data. how last count effectively. i found var lastrow = cells.find("*", [a1], , , xlbyrows, xlprevious).row; but namespaces not comprehend. me complete , correct answer ? i have come senario few days before, did read data , put in data table, , filter data show records when data not null. can go same approach.

i've got set of data @ work, need analyze , summarize based on daily values. have 48 values each date; 1 each half hour. i've set sumif , countif-system calcuate average values, need solution display data 1 date, can assess whether data complete (the supplier known have missing data in sensors) as example, data looks like. have 6000 lines of time. come in chunks time time, never know how big data set get. last 1 2200 lines 11-03-2016 11:30:00:000 13,3 51,6 7,85 11-03-2016 12:00:00:000 14,9 51,6 7,85 11-03-2016 12:30:00:000 13,9 51,6 7,86 11-03-2016 13:00:00:000 14,9 51,7 7,87 11-03-2016 13:30:00:000 14,7 52 7,87 11-03-2016 14:00:00:000 14,7 52 7,88 11-03-2016 14:30:00:000 0,1 52,1 7,89 11-03-2016 15:00:00:000 0,1 52,2 7,89 11-03-2016 15:30:00:000 14,8 52,1 7,9 11-03-2016 16:00:00:000 14,8 52 7,9 11-03-2016 16:30:00:000 13,3 52 7,91 11-03-2016 17:00:0

sup! trying merge list of audio files on top of each other 1 audio file. followed answer on this question, doesn't work. tried this(the code below) doesn't work either(probably because javax not compatible android) even if know how usage of other libraries android, please, show it. thing ask should done locally, without using servers. thank you! public class joinwavs{ public static void main(string[] args) { string wavfile1 = "d:\\wav1.wav"; string wavfile2 = "d:\\wav2.wav"; try { audioinputstream clip1 = audiosystem.getaudioinputstream(new file(wavfile1)); audioinputstream clip2 = audiosystem.getaudioinputstream(new file(wavfile2)); audioinputstream appendedfiles = new audioinputstream( new sequenceinputstream(clip1, clip2), clip1.getformat(), clip

i looking @ shell code meant count of number of files in directory. reads: count=$(ls -1 ${dirname} | wc -l) what -1 part mean? can't find in other questions, passing references iterating on files in directory isn't looking at. also, removing command seems have no effect. count=$(ls -1 ${dirname} | wc -l) ...is buggy way count files in directory: ls -1 tells ls not put multiple files on single line; making sure wc -l then, counting lines, count files. now, let's speak "buggy": filenames can contain literal newlines. how version of ls handles implementation-defined; versions double-count such files (gnu systems won't, wouldn't want place bets about, say, random releases of busybox floating around on embedded routers). unquoted expansion of ${dirname} allows directory name string-split , glob-expanded before being passed ls , if name contains whitespace, can become multiple arguments. should "$dirname" or "${di

i new android , have fragment container view (a framelayout). there 2 textviews on top of it, tabs. each textview ie txt1,txt2 adds 2 fragments ie frgmnt1,frgmnt2 respectively. when textview clicked, corresponding fragment added. if clicked again, fragment removed. that part working fine. however, when click in textview rapidly, app crashes , shows "no host" exception. can me understand why happens? (side note, tab layout implementation not required here). here stack trace: 07-04 18:22:25.600 10971-10971/integral.com.sellfie e/androidruntime: fatal exception: main process: integral.com.sellfie, pid: 10971 java.lang.illegalstateexception: no host @ android.support.v4.app.fragmentmanagerimpl.movetostate(fragmentmanager.java:1239) @ android.support.v4.app.fragmentmanagerimpl.movetostate(fragmentmanager.java:1234) @ android.support.v4.app.fragmentmanagerimpl.dispatchactivitycreated(fragmentmanager.java:2046) @ android.support.v4.app.fragment.perform

i have 2 perpendicular unit vectors, p , q; think of being embedded in rigid object in 3d space. wish rotate object p points along positive x-axis , q points along positive y-axis. i programming in c# , using quaternions compute rotations. how create quaternion perform desired rotation? if imagine inverse operation of quaternion, know point (1,0,0) goes p, , (0,1,0) goes q. similarly, point (0,0,1) go point z equal cross product of p , q. therefore have matrix representation of inverse rotation. first column p, second q, third p cross q. so matrix rotation want given transpose of matrix, i.e. first row p, second row q, third row p cross q. so recommend call library routine convert matrix quaternion form. you may interested in document doom3 explaining algorithm id software used converting matrix quaternion - including optimised x86 assembler code. orthogonal matrices if have matrix m columns (a,b,c) forming orthonormal set, know a'a = b'b = c'c

i've had look, can't find answer problem already. i trying upload downloadable product in magento 1.9. getting: ssl error: invalid or self signed certificate this problem happening 1 file. no problem images , other files. the size of file 2mb, can upload different file 3mb, same format in same place , works fine. think problem not size or format of file. i have uploaded around 45 images , 45 pdf files without error, particular file i've had error 50 times. i have cleared magento's cached , tried logging out , in again - no positive result. i've tried renaming file - no joy.

i have stored proc has following (simplified example): declare @id int = null select * table1 t1 inner join table2 t2 on ((@id not null) , (t2.id = @id)) the purpose of return rows if @id not provided, else return rows matching @id. works expected long @id provided. returns no rows @id null. i thought, maybe inner join table t2 on (@id null or ((@id not null) , (t2.id = @id))) might work, if @id null, seems return unending rows (i waited 30 seconds, , past 1m rows. (there 150 rows in table1) i've read around, , other examples accomplish seem use dynamic sql (which i'd rather not do), or possibility of creating temp table, seems little extreme kind of thing. what options? thank you. i doubtful on table joining, tried simplified sql query declare @id int = null select * table1 t1 inner join table2 t2 on t1.id=t2.id @id null or t2.id = @id

good day all, i have list of items want user able select 5 out of 10 items , 5 able send data off webservice. i found this , this but neither of them worked or github repo non existent (the second one). does have other tuts on how this? thank you what going on proplem? video ( https://www.youtube.com/watch?v=7du30yal6ri ) expectation? in example, create empty class , simple recyclerview. the view item handle user click behaviour. if user selected item click again item not select , otherwise. when action happening, have listener send mainactivity (implemented onitemchangelistener method of interface defined in adapter ) in mainactivity, create layout recyclerview, delete button, , no items labels. delete button process delete , update list data. the source code at: https://github.com/liemvo/example_recyclemultiselected

for fun, i'm trying implement chudnovsky algorithm calculate pi in java using arbitrary precision floating point library. 1 thing strikes me need calculate reciprocal of number 1/n, since formula described 1/pi = sum(...) how many significant digits/digits of precision 1 need of floating point number n, in order 1/n have desired precision? there easy answer this? tried doing calculations 1/0.100009999999 = 9.99900010009 determine reciprocal of 0.1 5 correct digits after decimal point. see if take first 3 digits after decimal point, , round result correct value 10, there general rule how many digits correct after 1/n operation? interested in same result in binary , hexadecimal bases. tried googling , fast search on stackoverflow, didnt find previous answer this. apologies if duplicate exists. you want compute 1/x, computing 1/(x+d) d=delta x truncation error. binomial theorems, 1/(x+d) = (x-d)/(x²-d²) and since can assume d² far below floating point error, error

this question has answer here: understanding python super() __init__() methods [duplicate] 7 answers i trying understand objects created when instantiate child class in python, example: class car(): def __init__(self, make, model, year): self.make = make self.model = model self.year = year class electriccar(car): def __init__(self, make, model, year): super().__init__(make, model, year) my_tesla = electriccar('tesla', 'model s', 2016) when create object my_tesla, instantiate class electriccar calling constructor of class, in turn calls constructor of parent. how happen? right have 2 guesses: 1) super() reference parent class, call constructor of parent "super(). init (make, model, year)" instantiating our child class. result have one object of our class electriccar(). 2) super(), calls c

i read replace not modify string, creates new 1 requested modifications. else implementation detail, should not care about. if don't trust regex library, don't use it. if behaves want to, might change in future without further notice. how use variable modification ? regex.replace , string immutability string immutable. means cannot modify existing string , can create new one. however, can modify reference string . for example: var = "hello"; var b = a; b = "world"; console.writeline(a); console.writeline(b); output: hello world this because when b = "world" called change reference b point "world" , a still points "hello" .

so i'm learning java, i'm novice. book provide source code, play around with. i create java project , move source code according folder. programs under main folder work perfect! when have seperate folders(subfolders main), guess project technically, programs not compile or run. they work if move take them out subfolder, not want that. lot of subfolders similar each other, don't want overwrite,etc. how go fixing without having create individual projects each of these? example. create new project -> chp10 under chp10 store source code give me. some of source code contain own folders, such rectangle 1, rectangle 2. everything under chp10 runs/compiles fine. if try use under rectangle folders not work. i believe error file not being resolved because references different class files. i had same issue way when. use import statement @ top of page you're implementing subfolder. example - @ top of java class file: package rectangle1; package

i trying plot curve molecular dynamics potential energies data stored in numpy array. can see figure attached, on top left of figure, large number appears related label on y-axis. @ it. if rescale data, still number appears there. not want it. please can suggest me howto sort out issue? thank much.. this happening because data small value offset large one. that's - sign means @ front of number, "take plotted y-values , subtract number actual values". can remove plotting mean subtracted. here's example: import numpy np import matplotlib.pyplot plt y = -1.5*1e7 + np.random.random(100) plt.plot(y) plt.ylabel("units") gives form don't like: but subtracting mean (or other number close that, min or max , etc) remove large offset: plt.figure() plt.plot(y - np.mean(y)) plt.ylabel("offset units") plt.show()
