i have development directory contains checkouts svn repositories stays in non svn directories. update of dirs being in svns. dir structure similar 1 below: how solve issue? i came "brute force" solution, not intelligent: for in `find . -mindepth 1 -maxdepth 3 -type d | grep -v .svn`; svn $i; done it nice have sth have: svn --recursive update development_dir. unfortunately, svn not support feature. can do, however, optimize command eliminating loop , piping grep. command should this: find . -mindepth 1 -maxdepth 3 -name "*.svn" -type d -exec svn {}/.. \; to make life easier, can set bash alias, example: alias svn_up_recursive='find . -mindepth 1 \ -maxdepth 3 -name "*.svn" -type d -exec svn {}/.. \;' ... , invoke whole script svn_up_recursive command. or create shell script , put bin directory. prefer shell scripts easier support, extend them, process command line arguments etcetera.

one thing miss moving svn mercurial mercurial's hg log command insists on showing history rather history of current working revision. for example, i'm working on repo lot of check-ins head within branch, , first 20 log entries have nothing line of development. there bunch of options hg log, but... --rev shows revision asked not ancestors --branch doesn't work because active head in same branch mine --prune removes ancestors of other head, if they're ancestors --user doesn't work because i'm not user in line of development i guess hg strip, seems overkill... thoughts? ryan if you've got mercurial 1.6 or later, can use revsets this: hg log --rev "ancestors(.)" hg log --rev "reverse(ancestors(.))" # output in same order vanilla hg log

i'm writing unit tests against database, , we're using transactions make sure our test data gets removed @ end. i'm running problem methods i'm testing using own transactionscope objects, , seems blocking when hitting database. this inside test's base class: basescope = new committabletransaction(new transactionoptions() { isolationlevel = isolationlevel.readuncommitted, timeout = new system.timespan(0, 5, 0) }); and inside method i'm testing, does: using (transactionscope scope = new transactionscope()) the first time code inside 2nd scope touches database, hangs. have way around problem? if using database not doing unit testing, , problems experiencing 1 of reason why true unit testing uses mocks , stubs. now tests doing valuable, , in cases them instead of unit testing. label integration testing (eit). key point here find whole new class of bugs when working real thing not unit test mocks. , key here real thing. fake environment art...

$result = mysql_query("select * users"); $values = array(); while($row = mysql_fetch_array($result)) { $values[] = array($row['tried']); } return $values; that returns word array when being called webservice. missing or doing wrong? it's not returning word 'array', it's telling being returned array. to see in array, use either var_dump($values); or print_r($values); . difference format of display. in addition, don't believe need declare array in assignment $values . $values[] = $row['tried']; should work. $values still array.

i created system using php.. on system..there form...in form has submit button , view in pdf button .. question how transform php form pdf form..user can view form in pdf format did not submit form yet , details enter appear in pdf format form..please me.. you'll need create form in acrobat pro, pdfpen pro, foxit reader (with appropriate add-ons), etc. in doing that, can include form control button submits form values url post. write php script receive post similar html form post, , you're go. from there, post pdf site , let visitor's pdf tools rest. note form validation handled in-pdf. tool use create form include bunch of ready-to-go validations can use (e.g., phone number or social security number), , if something's missing, can incorporate javascript. note js runs in pdf reader, not browser, it'll work if user has js turned off.

i have: ienumerable<foo> foolist and want convert to: ienumerable<bar> barlist is there linq / lambda solution move 1 other both objects (foo , bar) have simple properties going convert. example: bar.myyear = foo.year they each have 6 properties you can do: ienumerable<bar> barlist = foolist.select( foo => new bar(foo.year)); // add other construction requirements here... enumerable.select projection function, perfect type conversions. help: projects each element of sequence new form. edit: since bar doesn't have constructor (from comments), can use object initializers instead: ienumerable<bar> barlist = foolist.select( foo => new bar() { year = foo.year, month = foo.month // add other properties needed here... });

i have udf of joins , when run it, read 100-150 pages (from sql profiler) if wrap udf in sp sp read 243287 pages. furthermore, udf performs index seek sp performs index scan on 1 of searched columns. can please advise? based on comments (custid = @param1 or @param1 null) vs. (custid = @param1) , think gail shaw's blog posting on catch-all queries provide insight you're seeing here. basically, think you're getting execution plan cached @param1 null case performs poorly when pass in real @param1 .

i using microsoft sync framework 2.1 sqlserverce. have main table child table linked foriegn key. when delete main table entry, fails since there items in child table (which have been deleted.) how tell sync order delete rows tables in? the order in syncing tables matters. when dealing parent/child relationships must make sure specify child elements first , parents. project implemented sync framework, had child , parent table each in own syncscope, , had child scope done before parent scope since having 2 tables in ordered correctly in same scope did not seem guarantee order.

i have onchange event needs dynamically select id , add preset classname pass function. onchange = "show(document.getelementbyid(this.value). {select class here? } );" the equivalent in jquery $('#'+this.value+'.myclassname').function(); so how select id+classname in javascript? know i'm being dense. you need use classname? ids should unique. var element = document.getelementbyid('myid'); or element parent , want child class var elements = element.getelementsbytagname('*'); var newelements = []; (var = 0, length = elements.length; < length; i++) { if ((' ' + elements[i].classname + ' ').indexof(' yourclassname ') > -1) { newelements.push(elements[i]); } } this code walks through children, , uses indexof() test presence of class. if finds it, pushes onto new array.
