is there way set schema query in rest of query can refer tables name without prepending them schema name? for instance, this: use [schemaname] select * [tablename] as opposed this: select * [schemaname].[tablename] a quick google pointed me this page . explains sql server 2005 onwards can set default schema of user alter user statement. unfortunately, means change permanently, if need switch between schemas, need set every time execute stored procedure or batch of statements. alternatively, use technique described here . if using sql server 2000 or older this page explains users , schemas equivalent. if don't prepend table name schema\user, sql server first @ tables owned current user , ones owned dbo resolve table name. seems other tables must prepend schema\user.

i have textbox in user can enter time (eg: 01:00) , drop down box entering am/pm fields. (since am/pm field used, 12-hour time format used.) the text box allows max entry of 5 chars (eg: 01:00). how can set 3rd char default colon : , user has enter time. how check if time entered user numeric or not?. autocomplete feature: example, if user enters 1 automatically set 01:00 javascript validations 12-hour format. eg: if user enters 13:00 should change 01:00 how can append text box time values am/pm value selected in drop down box?. once values appended, automatically populate text box (text box 2) result. eg: 01:00 + pm should set 01:00p in new text box (text box 2). any appreciated. better have textbox size , maxlength of 2 named "txthours", colon label (span tag) , textbox named "txtminutes". easier manage. instead of checking, have onkeypress code returns false when key pressed not number allowing digits. best done in onblur event, if...

i trying generate list of numbers (that can use in for/foreach cycle). any number should 10 digits long , have initial prefix (i.e. 0851) 0851xxxxxx , go 0851000000 0851999999 range('0851000000','0851999999') however array take as 84mb in memory (as reported memory_get_usage(1) ) less memory consuming way generate these numbers on fly, while iterate in loop. for example for($a = 851000000; $a <= 851999999; $a++) { $number = '0'.(string)$a; dosomethingwith($number); }

i want install hadoop on round-robin dns environment. have bunch of machines sharing common user environment , common name. these machines equal. round-robin dns runs on branch of machines. each machine has own ip address , host name. our school's machines. these machines share common name. when login, terminal shows machine on. the problem make change on 1 machine, changes applies other machines. i follow instruction of michael-noll's multi-node hadoop. need configure master node. did master node applies slave nodes. said, cannot differentiate master , slave nodes. so, can install hadoop in such environment? i'm not quite sure why want install hadoop using round-robin dns, no, cannot hadoop. every single node needs have unique host name.

lets assume have following java code: public string foo() { // returns foo() string log = "foo() : logging something!" return log; } can search in eclipse foo() occurring in string literal, not anywhere else in code? in example here eclipse should find third occurrance of foo() , not first one, function name , not second one, comment. edit: simple regular expressions won't work, because find foo() in line like string temp = "literal" + foo() + "another literal" but here foo() function name , not string literal. you can try this: "[^"\n]*foo\\(\\)[^"\n]*" you have escape brackets, plus regex not match new lines or additional quotes, prevent wrong matches.

when thread being blocked necessary thread blocks other threads in same process or process?is happening every time? sure. wouldn't have cope deadlock if wasn't case. scenario blocked thread acquired synchronization object thread tries acquire well. block. okay, question now. generally, yes. other code needs run release blocking condition. non-obvious cases kernel threads run code in drivers if thread blocked on i/o. or thread scheduler, in case thread blocked because waiting acquire processor or waiting non-infinite time-out.

i need work out way create 10,000 non-repeating random numbers in php, , put database table. number 12 digits long. what best way this? this assumes can generate 12 digit random number without problems (use getrandmax() see how big can get....according php.net on systems 32k large number can get. $array = array(); while(sizeof($array)<=10000){ $number = mt_rand(0,999999999999); if(!array_key_exists($number,$array)){ $array[$number] = null; } } foreach($array $key=>$val){ //write array records db. } you use either rand() or mt_rand(). mt_rand() supposed faster however.

i need validate textbox input credit card number. have regex different credit cards: visa: ^4[0-9]{12}(?:[0-9]{3})?$ mastercard: ^([51|52|53|54|55]{2})([0-9]{14})$ american express: ^3[47][0-9]{13}$ and many others. the problem is, want validate using different regex based on different users. example: user1, visa , mastercard available, while user2, visa , american express available. generate final regex string dynamically, combining 1 or more regex string above, like: user1regex = visa regex + "||" + mastercard regex user2regex = visa regex + "||" + american express regex is there way that? thanks, you did not state language whatever reason suspect it's javascript. var user1regex = new regexp('(' + visaregex + ")|(" + mastercardregex + ')'); can use (?:) speedier execution (non-capturing grouping) have omitted readibility.

i building website on wich people can infos based on weight , height. how 1 structure query give me row 2 specific values closest ones users enter? i found this on stackoverflow , helpful. trying accomplish similar 2 values insted of 1. if weight , height of equal importance, can use (linear) select top 1 * tbl order abs(weight-@weight) + abs(height-@height) a better option weigh differences, on scale, such making 0.01m (1cm) of height of equal importance 1kg. square both sides well, deviation of 5cm , 5kg seen "closer" 10cm , 0kg. (assuming inputs in kg , metres) select top 1 * tbl order abs(weight-@weight)^2 + (abs(height-@height)*100)^2

while trying apply policy-based design, got stuck on 1 (simplified): template <class tprintpolicy, typename t> struct : private tprintpolicy { using tprintpolicy::print; t t; void foo() { print(t); } }; struct intpolicy { void print(int n) { std::cout << n << std::endl; } }; int main(int argc, char* argv[]) { a<intpolicy, int> a; a.foo(); return 0; } and here's question: how should redefine class possible provide policy parameter template, let infer t on own, this: a<intpolicy> a; preferrably, policy definition should not more complicated now. ideas? edit: forgot mention not want policy export typedef. of course easy solution, cannot infer type of t on own? make typedef within each policy gives policy's data type. template <class tprintpolicy> struct : private tprintpolicy { using tprintpolicy::print; typename tprintpolicy::data_type t; void foo() { ...

i have there dropdown lists values, , 1 textarea write valuse in. when press button writes values of 3 selected dropdown lists, every time when press button (it 3 times). pice of code writes values of dropodown lists, this: button pressed first time: "conntent of dropdown lists" undefinedundefined button pressed second time: undefined"conntent of dropdown lists"undefined button pressed third time: undefinedundefined"conntent of dropdown lists" but want values of dropdown list not "undefined" what can think of? var = 0; function inc(){ i++; if (i == 1){ var ukupnaporudzbina1 = vrstename + ' -> ' + podvrstename + ' -> ' + velicinename + i; }else if (i == 2){ var ukupnaporudzbina2 = vrstename + ' -> ' + podvrstename + ' -> ' + velicinename + i; }else if (i == 3){ var ukupnaporudzbina3 = vrstename + ' -> ' + podvrstename + ' -> ' + velicinename + i; } var porudzba = ukupnapo...

i've got custom layout want use titlebar of android app. technique found (linked @ bottom) works, system titlebar displayed before oncreate() called. looks pretty jarring, moment system titlebar shown, custom titlebar shown: // styles.xml <resources> <style name="mytheme"> <item name="android:windowtitlesize">40dip</item> </style> </resources> // 1 of activities, mytheme applied in manifest. protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); requestwindowfeature(window.feature_custom_title); setcontentview(r.layout.my_activity); getwindow().setfeatureint(window.feature_custom_title, r.layout.my_custom_header); } i hide system titlebar , display own in-line perhaps each , every layout, but, that's not friendly. thanks http://www.londatiga.net/it/how-to-create-custom-window-title-in-android/ i think it's framework limitation. had same p...

django's user authentication system ( http://docs.djangoproject.com/en/dev/topics/auth/ ) incredibly helpful in working users. however, documentation talks password reset forms , makes seem takes care of same way user login/logout. the default url login , logout is /accounts/login/ & /accounts/logout are there defaults changing password, or have build functionality? if @ django.contrib.auth.urls can see default views defined. login , logout , password_change , password_reset . these urls mapped /admin/urls.py. urls file provided convenience want deploy these urls elsewhere. file used provide reliable view deployment test purposes. so can hook them in urlconf: url('^accounts/', include('django.contrib.auth.urls')), as want customize views (different form or template), in opinion redefine these urls anyway. it's starting point nevertheless.

from know, ctr mode doesn't use initial vector. takes counter, encrypts given key , xor's result plaintext in order ciphertext. other block cipher modes cbc before doing encryption xor plaintext initial vector. so here problem. have following code in java(using bouncycastle library): cipher cipher = cipher.getinstance("aes/ctr/pkcs5padding", "bc"); cipher.init(cipher.encrypt_mode, key); byte[] result = cipher.dofinal("some plaintext"); every different call of above code same key gives different output! when doing: byte[] iv = new byte[]{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; cipher cipher = cipher.getinstance("aes/ctr/pkcs5padding", "bc"); cipher.init(cipher.encrypt_mode, key, iv); byte[] result = cipher.dofinal("some plaintext"); i take same result in every call of above code. why this? mean, ctr doesn't need iv, why when don't give iv in every call different result , when given ...

i have table name-value pairs , additional attribute. same name can have more 1 value. if happens want return row has higher attribute value. table: id | name | value | attribute 1 | set1 | 1 | 0 2 | set2 | 2 | 0 3 | set3 | 3 | 0 4 | set1 | 4 | 1 desired results of query: name | value set2 | 2 set3 | 3 set1 | 4 what best performing sql query desired results? this solution perform best: select ... table t left join table t2 on t2.name = t.name , t2.attribute > t1.attribute t2.id null another solution may not perform (you need evaluate against data): select ... table t not exists ( select 1 table t2 t2.name = t.name , t2.attribute > t.attribute )

i'm working on scientific/engineering programs written in fortran 32bit unix system , have recompile new 64bit cluster , having trouble making sense of errors , changes should make. i compile fortran programs 32-bit or 64-bit oses , haven't encountered problems. errors have seen? changing parallel program? a program implemented best design philosophy of fortran >=90 requests numeric types according precision needs, e.g., using "selected_real_kind" specify number of digits needed in real type. compiler (on os , host computer) provides requested precision if can, or otherwise program refuses run. if requested precisions sufficient compute answer, approach should make portable program. isn't perfect since numeric computing model isn't totally specified.

i guessing key of less-simple simple substitution ciphertext. rule evaluate correctness of key number of english words in putative decryption. are there tools in java can check number of english words in string. example, "thefoitedstateswasat"-> 4 words "thefortedxyzstateswasathat"->5 words. i loaded words list , using hashset dictionay. dont know inter-word spaces belong in text, can't validate words using simple dictionary. thanks. i gave answer similar question here: if word made of 2 valid words it has java-esque pseudocode in might adaptable solves problem.
