actionscript - Flash AS2 (CS4) - setInterval causing for loop to not work -

-

i have simple code:

    function testing(){        (a=1; a<=4; a++) {            this["btn"+a].enabled = true;        }     }

if run function anywhere works fine. if run function mytimer = setinteval(testing, 3000); not work. if add other random code function (the newly added code only) work. have narrowed down this["btn"+a].enabled = true; causing not run.

i hope makes sense, appologies, it's 3am :(.

any ideas?

what makes sense. when call function normally, "this" object. when run using setinterval, lose reference "this."

- edited based on comments others -

here 3 ways solve problem:

this way involves passing in "this" function:

var = this; setinterval(function() {testing(that)}, 1000);  function testing(obj) {     (a = 1; <= 4; a++) {         obj["btn" + a].enabled = true;     } }

this way involves passing in "this" setinterval:

setinterval(this, "testing", 1000);  function testing() {     (a = 1; <= 4; a++) {         this["btn" + a].enabled = true;     } }

the third way involves delagate class:

import mx.utils.delegate;  setinterval(delegate.create(this, testing), 1000);  function testing() {     (a = 1; <= 4; a++) {         this["btn" + a].enabled = true;     } }

c++ - Convert big endian to little endian when reading from a binary file -

-
this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

linq to sql - Linq2EF: Return DateTime with a TimeZone Offset -

-
our database has times stored utc, , know user's current timezone, want return relative that. want incorporate offset in linq projection so: var users = u in this.context.users select new userwithcorrecteddate { id = u.id, firstname = u.firstname, lastname = u.lastname, registrationdate = u.registrationdate.value.addhours(-5) }; of course, linq2ef cannot convert " addhours " canonical function. there way this? update: another thought, if timezone offset stored in database column, there way have db perform calculation (date + offset)? linq entities supports sqlfunctions. if know offset number of hours this: var users = u in this.context.users select new userwithcorrecteddate { id = u.id, firstname = u.firstname, lastname = u.lastname, registrationdate = sqlfunctions.dat...

gdi+ - WxWidgets draw a bitmap with opacity -

-
how can draw wximage, or wxbitmap dc opacity? looks not possible standard dc or wxgraphicscontext. beginlayer/endlayer not yet implemented in wxgraphicscontext have been 1 solution. gdi+ doesn't seem support layers, non-trivial add this. the solution seems to programmatically alter alpha channel pixel-by-pixel? void yourcustomwindow::onpaint( wxpaintevent& event ) { wxpaintdc dc(this); wximage image( width, height ); image.initalpha(); unsigned char* imgdata = img.getdata(); unsigned char* imgalpha = img.getalpha(); // manipulate raw memory buffers populate // them whatever image like. // putting zeros everywhere create // transparent image. // done, not quite... // wxdc can draw wxbitmaps, not wximage, // 1 last step required // wxbitmap bmp( image ); dc.drawbitmap( bmp, 0, 0 ); }
