  • A UI over Windows Workflow

    - by Tom
    Hi there, Are there any build in UI capabilities when using Windows Workflow.. Lets say I have a workflow that takes an hour to run where different activities are happening all the time. While it's running I want to see what activity is currently active, what activities have already ran etc.. Do I have to code this UI myself or does WF have built in features that graphically show the status etc of the workflow?

  • SVN: Recurisvely add files?

    - by Mark
    I'm trying svn add *.py --force As the documentation suggests, but I know for a fact it's missing files nested in deeper folders. Why? Is there a standard way to do this with other unix commands too? */*.py will nab a few more files, but it's kind of a pain in the butt to do this for every possible depth.

  • How should i store availability calendar information in mysql? for [id] [date] [available/unavailab

    - by Haroldo
    I'm building a simple calendar for holiday cottages to show when they are booked or available. What would be the fastest mysql table design for this, bearing in mind when users mark dates as available/booked they will do so via a start date and an end date. i can see 2 obvious options Store 'booked' data for every day [more rows] or, store 'booked' data with 2 columns a start_date and end_date [more processing?] Which is best or is there another method i'm missing?

    - by user1406269
    I am using wamp, PHP 5.4 running on win 8, I can't seem to get PHP to acknowledge the memcache dll. I download php_memcache-3.0.8-5.4-ts-vc9-x86.zip (the only one I could find). I copied the dll to C:\wamp\bin\php\php5.4.12\ext I added extension=php_memcache.dll restart the server. but still I cannot use memcache, and it is missing from Loaded Extensions list. Please supply a step-by-step instruction on how to set this up, Thanks.

  • Can you embed PHP code in the output of a CGI script?

    - by Joe Corkery
    I have a CGI based form that I am working with and I would like to be able to include some PHP code in the generated results. However, when I do this, the PHP does not appear to get processed and just ends up being displayed in the resulting web page. Is what I am doing actually possible or am I missing something? Thanks.

  • RESTful API: How to model 'request new password'?

    - by Jan P.
    I am designing a RESTful API for a booking application and was quite happy to see I could map all details of the application to the 4 HTTP methods. /users - GET, POST /users/({id}|myself) - GET, POST, PUT, DELETE /users/({id}|myself)/bookings - GET, POST /users/({id}|myself)/bookings/{id} - GET, POST, PUT, DELETE Example: Updating my own user uses a PUT to /users/myself. But now I found out that one thing is missing: The possibility to request a new password if I forgot my old one. Any idea how I could add this?

  • Field name being converted in Unit Tests [rails]?

    - by yar
    I am noting this strange behavior where one of my fields -- receive_empresa_test_info -- has worked fine though it's always been referred to as receive_empresa_info. In Functional Tests, though, the real field name is receive_empresa_test_info. What is going on here? Might this be some part of the Rails environment that I'm missing during testing?

    - by splix
    Are there exists an simple AMPQ server/broker implementation written in Java? I need it only for local integration tests, starting it from ant/maven, and i don't need any features like a clustering, persistence, performance and so on. Just a fake RabbitMQ-like instance, without installation (just as a dependency at maven pom) and configuration.

  • Memory leaks in libxml2.2

    - by KSH
    I am using libxml2 to parse xml content in my iPhone app. The xml content is downloaded from a server similar to the Apple's own TopSongs sample app. When I check for leaks using the Instruments tool, I see memory leaks being reported on xmlNewParserCtxt, xmlNewInputStream and xmlAllocParserInputBuffer. I have called xmlFreeParserCtxt(context) at applicable places (dealloc). Am I missing something else ? Is this a known issue to contend with when using libxml2 parsers ?

  • xdebug profiler output strange results

    - by nic28
    I'm using xdebug to profile some PHP code on Windows and using WinCacheGrind/Webgrind to analyse the output, but I'm getting some strange results. Specifically, the total cumulative time for a single method is greater than 100%! How is it possible that more time is spent executing this function's code and all the functions that it calls than the total time it took to execute the whole script? What am I missing here?
