[button.tagid settitle:@"hello"]; i don't want listener method, want modify button identifying tag. thanks in advance [(uibutton*)[scrollview viewwithtag:tagid] settitle:@"hello" forstate:uicontrolstatenormal];

it understanding when make copy of class defines pointer variable, pointer copied, data pointer pointing not. my question is: 1 assume "pointer copy" in case instantiating new pointer (dynamic memory allocation) of same type? eg., new pointer new allocation containing arbitrary memory address , 1 should take care point new pointer appropriate memory address? i presume there quite simple answer question, , apologize trivial nature, trying understand pointers @ deeper level , came upon researching pointers on internet. regards, chad the pointer copied value - both classes point same original memory, no new allocation takes place. shallow copy - language default. if need allocate new memory , make copy of data have in copy constructor. deep copy - have yourself edit: 1 of advantages of c++, free decide how copying works. might copy of object read access memory can avoid cost of copying memory. can implement classes make copy of original data if new obj...

never worked xml before, how come isn't validating: http://test.ipalaces.org/palnfo/template.xml with w3schools error: object # has no method 'load' you're using chrome, aren't you? xml fine; w3schools validator not. consider using different online validator, or installing 1 locally. may find you've got basic 1 installed somewhere already, depending on os (xmllint came pre-installed on mac, example.) incidentally, you're not "validating", technically, rather checking "well-formedness". validate you'd need dtd or xsd.

possible duplicate: re-entrant locks in c# why code not cause deadlock? private static readonly object = new object(); ... lock(a) { lock(a) { .... } } if thread holds lock, can "take lock" again without issue. as why is, (and why it's idea), consider following situation, have defined lock ordering elsewhere in program of -> b: void f() { lock(a) { /* stuff inside */ } } void dostuff() { lock(b) { //do stuff inside b, involves leaving b in inconsistent state f(); //do more stuff inside b consistent again } } whoops, violated our lock ordering , have potential deadlock on our hands. we really need able following: function dostuff() { lock(a) lock(b) { //do stuff inside b, involves leaving b in inconsistent state f(); //do more stuff inside b consistent again } } so our lock ordering maintained, withou...

very simple question time, have group of folders , of them contain files autoload whenever run sites script. not want have specify files autoload because want process dynamic , want able create , delete different files on fly. of course easiest solution list of folders in directories , build paths auto load files, if files exist script includes them. but, question how affect performance of script? framework want release later on performance quite issue. ideas? you should consider letting php autoload classes . if won't work, you're pretty left directory-scanning solution, , shouldn't care performance penalties. if want functionality, you'll put costs. generally shouldn't stress overmuch performance in php anyways. if becomes issue when framework complete , revisit it. chances you'll find whatever performance gains/losses incur rendered moot implementing caching system in framework. see premature optimization .

what difference in performance of following 2 queries in sql server 2008 query 1: select a.id,a.name,b.class,b.std,c.result,d.grade student inner join classes b on b.id = a.id inner join results c on c.id = a.id inner join grades d on d.name = a.name a.name='test' , a.id=3 query 2: select a.id,a.name,b.class,b.std,c.result,d.grade student inner join classes b on b.id = a.id , a.name='test' , a.id=3 inner join results c on c.id = a.id inner join grades d on d.name = a.name is there best way achieve best perofermance in above 2 queries you can have 100% guarantee execute same, same plan. the time matter when splitting and/where clauses in inner join when options force order used. great performance @ expense of writes, create these indexes: a (id, name) b (id) includes (class, std) c (id) includes (result) d (name) includes (grade) however, still depends on distribution of data , selectivity of indexes whether used. e.g. if grade table c...

in ext.charts, want create multi series chart (line + bar in 1 chart) gets data in store c#. is possible? there example can please show explain how works. definitely possible! have example graph line + bar in extjs demo pages itself: http://dev.sencha.com/deploy/dev/examples/chart/charts.html (refer last chart line , bar) regarding fetching data c#.. need url send data (xml or json). so, can have java,c#,python, php or other server side technology. extjs uses stores hold info, need have store, load data , associate store chart render data. ps: have series of tutorials @ blog - http://technopaper.blogspot.com/2010/05/getting-started-with-extjs-charts.html update have explained how handle charts series in blog. have @ above link. have similar chart (only think using line chart). json array returned server side is: [ {month:'jan', sales: 2000, rev: 3000},{month:'feb', sales: 1800, rev: 2900}, {month:'mar', sales: 1500, rev: 3100},{month...

i have bit of c code i've been working on in xcode on mac. wanted work on windows machine , compile tinyc. when run it, output different. is possible due using different compilers? thanks! edit 1 the code simple script opens wav file throw samples array. #include <stdio.h> #include <stdlib.h> #include <string.h> void read_wav_header(unsigned int *samp_rate, unsigned int *bits_per_samp, unsigned int *num_samp); void read_wav_data(int *data, unsigned int samp_rate, unsigned int bits_per_samp, unsigned int num_samp); int conv_bit_size(unsigned int in, int bps); int main(void) // int read_wav(void) { unsigned int samp_rate, bits_per_samp, num_samp; read_wav_header(&samp_rate, &bits_per_samp, &num_samp); printf("samp_rate=[%d] bits_per_samp=[%d] num_samp=[%d]\n", samp_rate, bits_per_samp, num_samp); int *data = (int *) malloc(num_samp * sizeof(int)); read_wav_data(data, samp_rate, bi...

for example have datagrid , want before databinding , after databinding, so: dgvtasksdoclist.savelayouttofile(); statuschangesextendedbindingsource.datasource = dt; dgvtasksdoclist.restorelayoutfromfile(); and want add such code cases when binding sources. there easy way write such code before/after action(sure can add 2 lines, may there known way of doing such things)? seems case aop - http://en.wikipedia.org/wiki/aspect-oriented_programming . for example postsharp able create attribute persistlayout , apply this: [persistlayout] public void binddatasource(object dt) { statuschangesextendedbindingsource.datasource = dt; } then postsharp extent source-code @ compile-time invoke additional two-lines. other idea might invoke these 2 methods in statuschangesextendedbindingsource.datasource property setter decision needs lot more context know.

i have existing application has requirement interacted mobile device. mobile device has wifi connection, , connecting pc hosting main application on lan. mobile device needs add/edit/find/delete objects main application maintaining. main application encapsulates functionality in simple repository classes. i believe approach add wcf service main application exposes set of methods mobile device can call against. have looked wcf today , tried setup example application, when called wcf methods unable access data, such feel wcf service running in own application domain , such has no access same static classes in main application. if setup wcf service project in vs 2008/2010, how can run under same application domain main winforms application, remote application on lan can communicate data application. below sample winform using system; using system.servicemodel; using system.windows.forms; using dataproject; namespace windowsformsapplication1 { public partial class form1 : ...
