  • How to create HTML tables from MySQL?

    - by Chris
    Hi Guys, I'm building a part of a system where the user can define "views" from a mysql database. I want some way of generating simple HTML tables/reports from the data, but not just plain output of sql queries- simple joins probably isn't enough. Any ideas?

  • LINQ Many to Many With In or Contains Clause (and a twist)

    - by Chris
    I have a many to many table structure called PropertyPets. It contains a dual primary key consisting of a PropertyID (from a Property table) and one or more PetIDs (from a Pet table). Next I have a search screen where people can multiple select pets from a jquery multiple select dropdown. Let's say somebody selects Dogs and Cats. Now, I want to be able to return all properties that contain BOTH dogs and cats in the many to many table, PropertyPets. I'm trying to do this with Linq to Sql. I've looked at the Contains clause, but it doesn't seem to work for my requirement: var result = properties.Where(p => search.PetType.Contains(p.PropertyPets)); Here, search.PetType is an int[] array of the Id's for Dog and Cat (which were selected in the multiple select drop down). The problem is first, Contains requires a string not an IEnumerable of type PropertyPet. And second, I need to find the properties that have BOTH dogs and cats and not just simply containing one or the other. Thank you for any pointers.

  • What kind of database to use in C#

    - by Chris
    I'm writing a program in C# that will need to store a few Data Tables on the user's computer and load them back when he restarts the program: Up to about 10000 records consisting of text and integers. I don't want to use a CSV file, and I had some trouble with SQLite. Are there any other good options to try?

  • Setting language/culture for reporting services report rendered through C#

    - by Chris Latta
    I have written a report renderer in C# that runs and attaches reports to an email. This is all working great, except the date format of the parameters are incorrect when listed in the report title. All the reports have their language set to =User!Language and the parameters are output using the FormatDateTime function to format according to the user's regional settings. I am basically using the rendering method described here on MSDN. This all works great when the reports are run through the browser. However, when I render the report from C# it uses en-US date format. The report server's regional settings are set appropriately to the correct region as are the regional settings of the computer the C# progam is running on.. What property do I need to set in my C# program for the report to be rendered using my appropriate language/culture?

  • Python if statement not working as expected

    - by Chris Esposito
    I'm searching for a string in a website and checking to see if the location of this string is in the expected location. I know the string starts at the 182nd character, and if I print temp it will even tell me that it is 182, however, the if statement says 182 is not 182. Some code f = urllib.urlopen(link) #store page contents in 's' s = f.read() f.close() temp = s.find('lettersandnumbers') if (htmlsize == "197"): #if ((s.find('lettersandnumbers')) == "182"): if (temp=="182"): print "Glorious" doStuff() else: print "HTML not correct. Aborting." else: print htmlsize print "File size is incorrect. Aborting."

    I'm trying to store an Image in my website so I can use it easily but I found this php code from here and I can't quite make much sense of it.. I'm just starting php and I dont quite know what to change and what to keep.. I'd greatly appreciate it if you could explain this a little better for me, thanks. <?php $allowedExts = array("jpg", "jpeg", "gif", "png"); $extension = end(explode(".", $_FILES["file"]["name"])); if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000) && in_array($extension, $allowedExts)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] .

  • Recommend a free/cheap CRM system [closed]

    - by Dan Hedley
    I am part of a 4 person volunteer team who manage a small housing development in London. We need a low-cost/no-cost contact management and issue tracking system. Specifically, it needs to be: -Web-based, or easily shared between 4 people working out of their homes -Easy to backup and restore -Decently secure Does anyone have any recommendations? I am reasonably technically literate, so a PHP-based solution running on a cheap hosting package would definitely be a viable option. Many thanks.

  • Pxe net install Centos with Static IP

  • PHP hits 100% CPU and eats RAM at the same time Monday to Friday

    - by Daniel Samuels
    We run a learning platform for primary schools here in the UK and it's all been running extremely well. However at around 4PM Monday to Friday we see the same issue arise -- 1-2 PHP threads will spike to 100% CPU and gradually start eating up RAM until the server(s) fall over. 98%+ of our requests are HTTPS, these come into our Layer 7 load balancer which then decrypts the SSL data, adds the X-HTTP-Forwarded-For header and forwards the data onto an application server (we have 2 of those at the moment) on port 80. Our application servers have Varnish on port 80 which takes in the request from the load balancer and passes the request through to Nginx on port 81. Nginx then works out which 'vhost' it needs to use and passes any PHP processing through to PHP-CGI which is listening on a socket (managed through spawn-fcgi). There's an instance of Memcached running too, MySQL runs on a separate server / slave setup. Throughout the day the load will typically go no higher than 0.8 on either of the application servers, however at around 4PM our problem arises. I've managed to run strace on a few of the actual threads when they cause the problem and I always see the same thing: stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 This is repeated infinitely and never stops until you SEGKILL the process or oomkiller kills it. There are no cron jobs scheduled to run at that time and I don't have any way of seeing exactly what Nginx request is associated with the PHP process which is running. We are running PHP 5.3.14 which we upgraded to from 5.3.8 last week to rule out the older version being the problem. This issue has been going on a few months now and we have no idea what is causing it. We deploy our software very frequently, so it's difficult to track down a specific release which may have started the problem - especially as we do not know the date of the first occurrence of this issue. Varnish is version 3.0.1, Nginx is 1.0.6 (which I understand is about a year old now), our servers are running CentOS release 5.7 (Final) they have Intel i3 540s at 3.07Ghz and 8GB of RAM. There's a discussion on the Debian mailing list about something very similar, you can find that here. Has anyone seen anything like this in the past, does anyone have any ideas or suggestions? Are there a way of linking an Nginx request directly to a PHP thread? Is there a better way of seeing what the PHP process is doing? (I've seen GDB mentioned, though I'll have to recompile PHP) Thanks!
