  • Silverlight and M-V-VM - Where should a timer live?

    - by Bill Jeeves
    I'm creating a simple monitoring tool in Silverlight. It talks to a web service to retrieve the status information and store it in the ViewModel. This needs to happen once per minute so I'm going to add a timer for this purpose (probably a DispatcherTimer). My question is, where should the timer go in an M-V-VM architecture? In the ViewModel or the View?

  • Language restrictions on iPhone partially lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through. (BTW this is a terribly important question for me an my product.)

  • linq subquery child collection to string

    - by bill
    Hi All, i am trying to figure out how to write a linq query that will return a child collections "name" property as a string. I have a BO that has a "options" property where the options are the "name" property of each option in an "order" object. I would like the result to look something like order.id = 12312 order.date = 12/03/10 order.options = "Option 1 Name, Option 2 Name, Option 3 Name" I hope this makes sense. thanks for any and all help!

  • How can an improvement to the query cache be tracked?

    - by Bill Paetzke
    I am parameterizing my web app's ad hoc sql. As a result, I expect the query plan cache to reduce in size and have a higher hit ratio. Perhaps even other important metrics will be improved. Could I use perfmon to track this? If so, what counters should I use? If not perfmon, how could I report on the impact of this change?

  • Trying to understand crash log output

    - by John Smith
    I'm trying to understand debug output from a crash log. I have the following line from the crashlog: 22 FG 0x00022b94 0x1000 + 138132 I understand how to use atos on 0x00022b94 to get the source code location. What I would like to know is why the crash log helpfully splits that number into 0x1000 + 138132? I have googled and the googles failed me.

  • Optimal way to initialize varying objects

    - by John Smith
    I have to initialize a lot of different types of objects based on an integer parameter. They all have the same overall initialization methods. At the moment I have the following code #def APPLE 1 #def PEAR 2 switch (t) { case APPLE: newobj = [[FApple alloc] init]; break; case PEAR: newobj = [[FPear] alloc] init]; break; default: retobj = nil; } I believe there must be a better way to do this. When I add FOrange I have to go and add another line here. What would be a better way?

  • Should I use ObservableCollections in my Model in M-V-VM

    - by Bill Jeeves
    I'm completely new to M-V-VM and very new to Silverlight, just reading about it for the first time today. As a sample, I am creating a model containing a list of items. My (Silverlight 4) View contains a listbox and my ViewModel will look to the model to retrieve the collection that the listbox will bind to. My question is this. I think it would be good to use an ObservableCollection to hold the items that the listbox binds to. This would be an ObseravleCollection in the ViewModel. Should I also use this type of collection in the model, or should I use another collection type and do smoe conversion between model and viewmodel?

  • Why is Zend Framework (Zend_Db_table) rejecting this SQL Query?

    - by Michael T. Smith
    I'm working on a simple JOIN of two tables (urls and companies). I am using this query call: print $this->_db->select()->from(array('u' => 'urls'), array('id', 'url', 'company_id')) ->join(array('c' => 'companies'), 'u.company_id = c.id'); which is out putting this query: SELECT `u`.`id`, `u`.`url`, `u`.`company_id`, `c`.* FROM `urls` AS `u` INNER JOIN `companies` AS `c` ON u.company_id = c.id Now, I'd prefer the c.* to not actually appear, but either way it doesn't matter. ZF dies with this error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1" but I can run that query perfectly fine in my MySQL CLI. Any ideas how to fix up this query?

  • How can i get the selected option name or id of a select element using jQuery

    - by bill
    Hi All, i have a "questionairre" that is made up of a series of select boxes. i need to use two properties in the options. For each selected option i need the value (which i know how to get and is working fine) but i also need to store an additional value which represents the id of the specific option in a DB. One solution would be to put the two values in the "value" property and parse it out.. but if there is some other property i can use that might be easier and clearer.. can i add a custom property?? like databaseId that could be accessed with jQuery? thanks for ANY suggestions.

  • Create a PHP cache system in MySQL database?

    - by Zach Smith
    I'm creating a web service that often scrapes data from remote web pages. After scraping this data, I have a simple multidimensional array of information to use. The scraping process is fairly taxing on my server, and the page load takes a while. I was considering adding a simple cache system using a MySQL database, where I create one row per remote web page with a the array of information pulled from it stored as a JSON encoded string. Is this a good enough system? Or would something like a text file per web page be a better idea?

  • Why is my SSH session timing out in less than a minute?

    - by John Smith
    Within a minute of connecting to my remote Linux server through SSH, my session times out and I cannot contact the server until a few seconds have passed. Meanwhile, I'm connected to other servers without interruption. This is only happening when I establish connection from an hotel wireless AP. When I connect from my phone's Internet, the problem does not occur. Does anyone know what might be causing these unusual timeouts?

  • padding not shifting my logo

    - by paul smith
    I have a logo link that's using a background-image (css sprite). All works fine, but when I try to add a 20px padding to the top of the link (to give it more space for user to click the link), the background image is not moving down. Here is my css: a { background-image:url("sprite.png"); background-repeat:no-repeat; display:block; height:70px; width:70px; padding-top:20px; /* give top of the link more click space */ } And my html: <a href="#" style="background-position:0 0;"></a> What am I doing wrong?

  • Load php file wth xml header

    - by John Smith
    I have a php file with an xml header and xml code, named test.php. How do I load this file as an xml? The following doesn't work: $xml = simplexml_load_file('test.php'); echo $xml; I just get a white page. The test file is saved as php, as it's dynamic. It's loading data from the tradedoubler api. The xml looks something like this: <voucherList> <voucher> <id>115</id> <programId>111</programId> <programName>Program 111</programName> <code>AF30C5</code> <updateDate>1332422674941</updateDate> <startDate>1332370800000</startDate> <endDate>1363906800000</endDate> <title>Voucher number one</title> <shortDescription>Short description of the voucher.</shortDescription> <description>This is a long version of the voucher description.</description> <voucherTypeId>1</voucherTypeId> <defaultTrackUri>http://clk.tradedoubler.com/click?a(222)p(111)ttid(13)</defaultTrackUri> <siteSpecific>True</siteSpecific> </voucher> <voucher> <id>116</id> <programId>111</programId> <programName>Program 111</programName> <code>F90Z4F</code> <updateDate>1332423212631</updateDate> <startDate>1332370800000</startDate> <endDate>1363906800000</endDate> <title>The second voucher</title> <shortDescription>Short description of the voucher.</shortDescription> <description>This is a long version of the voucher description.</description> <voucherTypeId>1</voucherTypeId> <defaultTrackUri>http://clk.tradedoubler.com/click?a(222)p(111)ttid(13)url(http://www.example.com/product?id=123)</defaultTrackUri> <siteSpecific>False</siteSpecific> <landingUrl>http://www.example.com/product?id=123</landingUrl> </voucher> </voucherList>

    I have a following query. It uses only one table (Customers) from Northwind database. I completely have no idea how does it work, and what its intention is.

  • In Perl, is there a built in way to compare two arrays for equality?

    - by Bill
    I have two arrays of strings that I would like to compare for equality: my @array1 = ("part1", "part2", "part3", "part4"); my @array2 = ("part1", "PART2", "part3", "part4"); Is there a built-in way to compare arrays like there is for scalars? I tried: if (@array1 == @array2) {...} but it just evaluated each array in scalar context, and so compared the length of each array. I can roll my own function to do it, but it seems like such a low-level operation that there should be a built-in way to do it. Is there? Edit: sadly, I don't have access to 5.10+ or optional components.
