having been avid reader here many years, have question of own couldn't find answer for. i looking solution, preferably vb scriptable, combines several pdf files different subfolders 1 new pdf , adds bookmarks based on folder structure, i.e. first page originating first file folder gets first level bookmark based on folder name, , second level bookmark based on file name. subsequent files folder second level bookmarks linked under first level bookmark. as added complication, bookmarks must point location in document; must not javascript based , call actions. this should happening on win7 pc. unfortunately don't know how internal workings of pdfs (yet), can't quite believe that problem uncommon isn't solved already!? can pointing me in right direction (or providing script, of course, if it's easy), or confirming above isn't possible, or else, really? thank much! best

Java, Catching an exception and passing it to a method -

i created method accepts ioexception argument. method opens out stream , prints information exception text file. problem seem running into.. how call method catch block? try{ if(true) throw new ioexception(); } catch(ioexception e){ //pass method } :::edit::: public void logerrors(ioexception e){ printwriter out = yada yada; out.println(e.getcause()); } basically have call name of method, want method's code executed this: try{ if(true) throw new ioexception(); } catch(ioexception e){ //pass method methodtoexecute(e); } also, can see throw ioexception in both cases perhaps may want consider modifying code use block edit on second thought, can use if statement throw always. if (...) { yourmethod(throw new ioexception()); }

How to plot the discrte form of the logistic model in matlab -

i want plot y(k) againts k of following formula in matlab: y(k+1)=r(y(k))(1-y(k)) so did following: %logistic model in discrete form. r=2.5; y=rand(1); j=1:100 y(j+1)=r*y(j)*(1-y(j)); end plot(y(j+1),j) but when run it, thing gives me white plot, is, axis. did wrong here?, can me fix it? thanks lot in advance. you need create array of values of function. %logistic model in discrete form. r=2.5; y = zeros(100, 1); y(1) = rand(1); j=1:100 y(j+1)=r*y(j)*(1-y(j)); end plot(1:101, y) plot function 2 arrays, first values of x axis, second values of y axis.

c - Why this code not giving desired output? -

#include <stdio.h> //compiler version gcc 6.3.0 int main() { float da,hra,s,gs; scanf("%f",&s); da=40/100*s; hra=20/100*s; gs=s+da+hra; printf("%f",gs); return 0; } for example if entered 25000 s output must 40000 showing 25000.000000. try fix below. note 40.0 , 20.0 instead of 40 , 20 . issue doing integer division. 40 / 100 == 0 , da 0 . using 40.0 / 100 instead gives floating point division , value 0.4 , want make calculations correct. (the same holds computation of hra .) #include <stdio.h> int main() { float da, hra, s, gs; scanf("%f", &s); da = 40.0 / 100 * s; hra = 20.0 / 100 * s; gs = s + da + hra; printf("%f", gs); return 0; }

python - For loop in matplotlib only plots first iteration -

i want read several columns csv file , plot them on single window. have this: fig1=pl.figure(num=1, figsize=(8, 4), dpi=80, facecolor='w',edgecolor='k') a=np.random.rand(50,9) ax = pl.gca() in range(0,6,2): ax.errorbar(a[:,i], a[:,i+1], yerr= a[:,i+2]) ax.set_xscale('log') ax.set_xlim(1e19, 1e22) pl.show() i no error message, output plot first iteration, when there should 3 in sample file. have put different parts of code in loop @ best first plot window , 2 empty windows not looking either. why isn't loop cycling through values? or assuming cycling through why plotting first one? thanks! update: tcaswell, x range restrictive. classical case of not looking @ data close enough. embarrassing.

c++ - What's the point of logical operators vs. bitwise operators -

given statement logical operation ((a > 5) && (b > 4)) and statement bitwise-operation ((a > 5) & (b > 4)) above 2 statements not equivalent. because (a > 5) element of {0,1} so, why need logical operators & bitwise-operation ? edit : of feedback. regarding short circuit behaviour of logical operators, not want behaviour - writing code gpu branches degrade performance: short circuit results in 2 branches instead of 1 in code. for numerical comparisons in c, in case short circuit not needed, seems logical , bitwise have identical behaviour. in case, bitwise ops faster logical. i apologize not putting these details in original posting. i think no, take example (0b - means binary): a = 0b00000010 b = 0b00000100 now, neither a nor b 0. a & b == 0 (due way bitwise , defined). however a && b != 0 (because logical , result 0 if @ least 1 operand 0 - not case a , b above). also there short circ

R: Number of obs between min and max -

i need extract number of observations between min , max. know can subset data, creating new df calculate length interested in less involved process. example, have , number of observations min max, ddd <- mydf[,list(minvar1 = min(var1, na.rm=true), maxvar1 = max(var1, na.rm=true)), by="group"] is there direct approach without intermediate df? thanks. edit: guess bit more complicated stated. group = 1, minimum value 2 need minimum indexed lower max value index/position. so, range 3 7 length of 3. idx variable scores measured index/position of var1. so, max position of var1 must first identified, insure min position extracted idx less of max position. group var1 idx 1 3 4 1 5 5 1 7 6 1 3 7 1 2 8 2 5 12 2 6 13 2 9 14 2 11 15 2 5 16 group min max length 1 3 7 3 2 5 11 4 by using data.table , expected output. convert 'data.frame' 'data.table' ( setdt(df1) ). grouped 'group', order 'idx', position of maximum

node.js - Divide Node App in different files -

i'm developing first node.js app socket.io , fine app getting bigger , i'd divide app-code different files better maintenance. for example i'm defining mongoose schemas , routings in main file. underneath functions socket.io connection. want have file schemas, file routing , 1 functions. of course, i'm aware of possibility write own module or load file require. not make sense me, because can't work vars app, io or db without making them global. , if pass them function in module, can't change them. missing? i'd see example how done in practice without using global vars.. it sounds have highly coupled application; it's difficult split out code modules because pieces of application should not depend on each other do. looking the principles of oo design may out here. for example, if split dataabse logic out of main application, should able so, database logic should not depend on app or io --it should able work on own, , require other p

sql server - Is there a better way to check the database for a unique value that works for both update and insert then below -

if exists(select * mytable (nolock) mytable.recordid <> @recordid , mytable.uniquecolumn = @uniquevalue) begin select 1 end else begin select 0 end note: use nolock checks pending inserts , update (i.e update / changing uniquecolumn) note: use "if exists(" stops search after finding first match note: use "mytable.recordid <> @recordid" not find match. note: if inserting recordid negative 1 or zero. don't know if it's "better", it's more to-the-point: select case when exists ( select * ... ... ) 1 else 0 end isthereornot ...and can used other expressions (if need 'em). note: select * appropriate existence checks, , nolock isn't going change - there's implicit transaction scope of select. i think it's better (easier use results consumers) if name columns (isthereornot in example)

say if have text box input user key in value. this value passed function, say: f(x,y) = x / y; where x,y user inputs. in case, if y == 0 , divide 0 error occur. my question practice, section of code should responsible error checking? it 1) read text box value, automatically change value else if equal 0. or 2) when 0 passed function f(x,y) , within function, handle potential divide 0 error. you want errors apply (such divide 0 error) caught function itself. don't want use function in different part , need rewrite same error checking (or worse, forget to).
