i'm in process of refactoring our specflow-implemented bdd tests. part of work, i've commented out of step definitions. as run tests, i'm presented "no matching step definition found 1 or more steps." message. however, i'd prefer not wait until tests run. there way specflow check missing step definitions without running tests? you can use stepdefinitionreport parameter specflow.exe, follows: specflow.exe stepdefinitionreport mytests.csproj but aware: if assembly uses .net 4.0 runtime, you'll need add specflow.exe.config file <supportedruntime> element. it uses functionality that's 32-bit only. if you're on 64-bit windows, you'll need use corflags /32bit+ edit specflow.exe file. by default, looks in bin\debug folder.

what best way remember windows position between application loads using obj-c? using interface builder interface, possible bindings. what recommended method? thank you. put name unique window (e.g. "mainwindow" or "prefswindow") in autosave field under attributes in interface builder. have location saved in user defaults automatically. to set autosave name programmatically, use -setframeautosavename: . may want if have document-based app or other situation doesn't make sense set autosave name in ib. link documentation .

currently i'm attempting write own wxobject, , class based off of wxtextctrl class. currently have: class commandtextctrl : public wxtextctrl { public: void onkey(wxkeyevent& event); private: declare_event_table() }; then later on have line of code, doesn't like: commandtextctrl *ctrl = new commandtextctrl(panel, wxid_any, *placeholder, *origin, *size); ...and when attempt compile program receive error: error: no matching function call ‘commandtextctrl::commandtextctrl(wxpanel*&, <anonymous enum>, const wxstring&, const wxpoint&, const wxsize&)’ it seems doesn't inherit constructor method wxtextctrl. happen know why doesn't inherit constructor? thanks in advance help! c++ not inherit constructors (you may thinking of python, does ;-). class w/o explicitly declared ctors, commandtextctrl , in c++, has default , copy ctors supplied implicitly c++ rules. so, need explicitly define ctor desi...

i found or without flags attributes, can bit operation if defined following enum enum testtype { none = 0x0, type1 = 0x1, type2 = 0x2 } i wondering why need flags attribute? c# treat them same either way, c# isn't consumer: propertygrid render differently allow combinations xmlserializer accept / reject delimited combinations based on flag enum.parse likewise (from string), , enum's .tostring() behave differently lots of other code displays or processes value treat them differently more importantly, though, expression of intent other developers (and code); this meant treated combinations, not exclusive values .

i've encountered error: system.data.sqlclient.sqlexception: transaction log database 'mydatabase' full. find out why space in log cannot reused, see log_reuse_wait_desc column in sys.databases on 1 of windows services. it's supposed retry after catching sql exception, didn't expect seemed data still going through (i'm using sqlbulkcopy btw) regardless of throwing exception. i've never encountered scenario before. i'd know if there other scenarios such thing might happen, , if thing entirely possible @ in first place? edit: system.data.updateexception: error occurred while updating entries. see innerexception details. ---> system.data.sqlclient.sqlexception: transaction log database 'my_db' full. find out why space in log cannot reused, see log_reuse_wait_desc column in sys.databases @ system.data.sqlclient.sqlconnection.onerror(sqlexception exception, boolean breakconnection) @ system.data.sqlclient....

i have problem solution choose.. have server running having service running can receive orders website. server several client (remote computers) connected somehow. i use wcf comunication, not sure it's possible. i dont wanna configure client firewall settings in routers, clients have connect server. but when order recieved on server, should transferred specific client. one solution have client connect using duplex binding, have somehow keep connection alive in order able received data server... way ?? normally connection times out , reason... anyone have insight problem. thx alot advise :-) best regards søren müller this duplex bindings designed for. 2 best choices have nettcpbinding or pollingduplexbinding . the former uses tcp protocol may not suitable clients if aren't on network. however, allow two-way communication on client-initiated socket. client doesn't need able accept incoming connections. used on project , works well. it's res...

i have source dll , have compiled version of lying around somewhere. if compile source have different date already-compiled version. how can tell whether in fact same , have merely been compiled @ different times? to compare 2 .dll files can use ildasm or other tool geting il code. have created sample embedded ildasm in dll file can use on every machine. when disassemble assembly check if ildasm.exe file exists in executing assembly folder , if not file extracted there our dll file. using ildasm file il code , save temporary file. need remove following 3 rows: mvid - wrote before unique guid generated every build image base (the image base tells program loaded in memory windows loader.) - different every build well time-date stamp - time , date when ildasm run so read temp file content, remove these rows using regexes, , save file content same file. here disassembler class: using system; using system.io; using system.linq; using system.reflection; using syst...

i’m trying createan observer on following event.: ‘sales_order_payment_pay’. however according magento doc http://www.magentocommerce.com/wiki/5_-_modules_and_development/reference/magento_events i don’t have parameters avalaible on event.. do have idea how retrieve customer object (i need info such customer id , customer email)? thanks feedback , anyway wish nice day, anselme this event expose payment object, should able chain off of object want: public function yourobserverfunction($event) { $payment = $event['payment']; $customer = $payment->getorder()->getcustomer(); // ... useful } generally objects in magento can chained this, , code doesn't rely on event being triggered customer session (which not assumption anyway). hope helps! thanks, joe

the man page xcodebuild reads: run xcodebuild directory containing project (i.e. directory containing projectname.xcodeproj package). i keep source directory (which subversion external) clean , unmodified, , build object files , executables location outside of source directory. is there way build separate build directory terminal using xcodebuild can make tools or msbuild on windows? you can set build settings command line. configuration_build_dir set build directory. example: xcodebuild -project yourproject.xcodeproj -configuration debug -target archs=x86_64 only_active_arch=yes configuration_build_dir=../some/other/dir a reference found on apple's site: build setting reference

the oreilly book "learning opencv" states @ page 356 : quote before totally lost, let’s consider particular realistic situation of taking measurements on car driving in parking lot. might imagine state of car summarized 2 position variables, x , y, , 2 velocities, vx , vy. these 4 variables elements of state vector xk. th suggests correct form f is: x = [ x; y; vx; vy; ]k f = [ 1, 0, dt, 0; 0, 1, 0, dt; 0, 0, 1, 0; 0, 0, 0, 1; ] it seems natural put 'dt' there in f matrix don't why. if have n states system, how spray "dt" in f matrix? the dt s coefficients of velocities corresponding positions. if write state update after time dt has elapsed: x(t+dt) = x(t) + dt * vx(t) y(t+dt) = y(t) + dt * vy(t) vx(t+dt) = vx(t) vy(t+dt) = vy(t) you can read f off of these equations pretty easily.
