  • How to access controls collection of dynamically loaded aspx page?

    - by Naasir
    Let's say I have two webforms, A.aspx and B.aspx, where B.aspx contains some simple web controls such as a textbox and a button. I'm trying to do the following: When A.aspx is requested, I want to dynamically call and load B.aspx into memory and output details of all the controls contained in B.aspx. Here is what I tried in the codebehind for A.aspx: var compiledType = BuildManager.GetCompiledType("~/b.aspx"); if (compiledType != null) { var pageB = (Page)Activator.CreateInstance(compiledType); } foreach (var control in pageB.Controls) { //output some details for each control, like it's name and type... } When I try the code above, the controls collection for pageB is always empty. Any ideas on how I can get this to work? Some other important details: both webforms utilize a master page (so the web controls in b.aspx are actually placed within a "content" tag) I've also tried using BuildManager.CreateInstanceFromVirtualPath. No luck.

  • Which data structure for List of objects + datagrid wiev

    - by Martin
    Hi, I have to develop a code which will store a list of objects, as example below 101, value 11, value 12, value 13 ...etc 102, value 21, value 22, value 23 ...etc 103, value 31, value 32, value 33 ...etc 104, value 41, value 42, value 43 ...etc Now, the difficulty is, that first column is an identifier, and whole table should always be sorted by it. Easy access to each element is required. Additionally, list should be easily updated, and extended by adding element at the end as well as in front and still keep being sorted by first column. Finally, I would like to be able to display values of the above in datagridview. What is most important is a performance of the implementation, as rows will be updated many times per second, and datagridview should be able to display all changes immediately. I was thinking about creating class for the values, and then a Dictionary but encountered a problem with displaying values in gridview. What would be the most optimal way of implementing the code? Thanks in advance Martin

    - by Jay
    I want to extend a WPF button to store some extra data, in a similar way to the current "Tag" property. Are attached properties the way forward? The data I want to store will be a URL Link string, for example I would like to be able to do something like: <Button Tag="BBC World News" URLLink="http://www.bbc.co.uk"/> Can anyone help me to understand how to extend the Button? Many thanks Jay

  • rake task via cron problem loading rubygems

    - by Matenia Rossides
    I have managed to get a cron job to run a rake task by doing the following: cd /home/myusername/approotlocation/ && /usr/bin/rake sendnewsletter RAILS_ENV=development i have checked with which ruby and which rake to make sure the paths are correct (from bash) the job looks like it wants to run as i get the following email from the cron daemon when it completes Missing these required gems: chronic whenever searchlogic adzap-ar_mailer twitter gdata bitly ruby-recaptcha You're running: ruby 1.8.7.22 at /usr/bin/ruby rubygems 1.3.5 at /home/myusername/gems, /usr/lib/ruby/gems/1.8 Run `rake gems:install` to install the missing gems. (in /home/myusername/approotlocation) my custom rake file within lib/tasks is as follows: task :sendnewsletter => :environment do require 'rubygems' require 'chronic' require 'whenever' require 'searchlogic' require 'adzap-ar_mailer' require 'twitter' require 'gdata' require 'bitly' require 'ruby-recaptcha' @recipients = Subscription.all(:conditions => {:active => true}) for user in @recipients Email.send_later(:deliver_send_newsletter,user) end end with or without the require items, it still gives me the same error ... can anyone shed some light on this? or alternatively advise me on how to make a custom file within the script directory that will run this function (I already have a cron job working that will run and process all my delayed_jobs. Cheers!

  • How to make an tiled background like on the web?

    - by mystify
    On the iPhone, how could I achieve the same tiled background effect? For example, I have an pattern image which I want to repeat only horizontally. Would I have to go the route in -drawRect: by myself and loop over to draw the pattern, or is there a convenient method to do that?

  • Citrix on ESX 4 U1 - Slow login times

    - by thomps01
    I'm sure they'd be just as slow if not slower using ESX 3 but I'm looking for some assistance. On a physical Citrix server, logins are 1 - 4 seconds. The virtual - 16 - 23 seconds. I'm looking for performance enhancements that I can make to me VMs to try and reduce the login wait times. The hardware is fine (HP BL685 (24 cores, 64GB RAM). And there's nothing pushing it yet. Network 10Gb I'm planning to test the configuration with VMXNET3 tomorrow, but does anyone have a list a best practices I can use when testing?

  • Group Policy dealing with IE zone assignment not sticking!

    - by Brandon
    I have a group policy (which ONLY deals with the zone assignment) -that is continually switching on and off with reboots. I thought it was a conflicting group policy but when I run group policy modeling report it doesn't show any descrepancies that I can see. I thought it may be an issue with one domain controller wasn't replicating my policy change to the other one, but this isn't the case. I checked both domain controllers and they show the same information. The assignment is on a user basis and is in: user configuration > administrative templates > windows components > internet explorer > internet control panel > security and is site to zone assignment.

  • Laptop monitor goes black under intense graphics

    - by drahcir
    I have a dell inspiron 1520 with a nvidia GeForce 8600M GT video card. I have Windows 7 professional as an operating system. Yesterday when I was using it the screen started to somewhat flicker then go completely black. I restarted it and in the boot screen everything seems fine, when I entered the login screen it became flickery again, and when I logged in, when a couple of windows popped up it went black again. I hooked it up to a tft monitor and the monitor works fine, and did some more tests that confirmed that under higher graphics causes the laptop monitor to go black. Is there a reason why this is happening?

  • Is there a good Lotus Notes open-source alternative?

    - by Ben S
    At my work we use Lotus Notes 6.5 for our email, meeting scheduling and instant messaging. I can't stand the horrible UI, buggy meeting scheduling and overall '90s feel when using it and would love to replace it with open-source alternatives. So far I've been able to setup Thunderbird for email, and I should also be able to configure pidgin to do IM, but I can't find any replacement for the meeting scheduling. I need to be able to receive meeting requests and respond to them. I've looked around trying to get the Thunderbird plugin Lightning to manage the scheduling, but everything I've read so far requires me to export .ics files from Lotus Notes or otherwise keep Lotus Notes around for day-to-day activities. I've also looked into using Evolution as the client, but I found even less information for it than I did for Thunderbird. How can I easily send, receive and respond to Lotus Notes meetings using an open-source alternative? Alternatively, if there exists a full drop-in replacement to Lotus Notes I would also consider it. Note: My desktop at work is a Windows XP machine, though I wouldn't be opposed to a solution requiring cygwin at this point. Edit: I have no power over the server. I only want a compatible client.

  • php memory how much is too much

    - by Rob
    I'm currently re-writing my site using my own framework (it's very simple and does exactly what I need, i've no need for something like Zend or Cake PHP). I've done alot of work in making sure everything is cached properly, caching pages in files so avoid sql queries and generally limiting the number of sql queries. Overall it looks like it's very speedy. The average time taken for the front page (taken over 100 times) is 0.046152 microseconds. But one thing i'm not sure about is whether i've done enough to reduce php memory usage. The only time i've ever encountered problems with it is when uploading large files. Using memory_get_peak_usage(TRUE), which I THINK returns the highest amount of memory used whilst the script has been running, the average (taken over 100 times) is 1572864 bytes. Is that good? I realise you don't know what it is i'm doing (it's rather simple, get the 10 latest articles, the comment count for each, get the user controls, popular tags in the sidebar etc). But would you be at all worried with a script using that sort of memory getting hit 50,000 times a day? Or once every second at peak times? I realise that this is a very open ended question. Hopefully you can understand that it's a bit of a stab in the dark and i'm really just looking for some re-assurance that it's not going to die horribly come re-launch day.

  • How to configure a subproject dependency in Maven without deploying jars?

    - by MikeHoss
    I googled this and it seems that no one has an answer, yet it seems like such an elementary thing that it should be possible. I have the following project structure: parent ---sub-project1 ---sub-project2 sub-project2 needs to have sub-project1 as a dependency. So I have this in sub-project2's pom: <dependencies> <dependency> <artifactId>sub-project1</artifactId> <groupId>mygroup</groupId> <version>1.0-SNAPSHOT</version> </dependency> .... When I do this, Maven tries to dowload the sub-project1.jar file, which does not exist because it's not ready for the repo yet. I tried to put a <scope>import</scope> in the dependency, but that didn't work either -- same result. So what do I have to do to get Maven to look at sub-project1 when building sub-project2?

  • Url mapping with my servlet?

    - by user291701
    Hi, I'm using GWT with GAE. When the user enters any of the following urls, I want to just serve my app as usual to them: http://www.mysite.com/ http://www.mysite.com/dog http://www.mysite.com/cat the first case works by default. I'm not sure how to get the /dog and /cat cases to work. I think I have to modify something with the url mappings to get that to work in web.xml. Essentially I'm trying to just get my app served with any url entered: http://www.mysite.com/* Thanks

  • Morphing from an image to a shape in Silverlight 3

    - by Moo
    Hi, I have a requirement to morph from an image (png) to a shape (polygon) in Silverlight 3 as an effect, but of course there is no built in transition or method to do this. At the moment the best I have is fade one out and the other in, but can anyone suggest a decent alternative that may work or look better? Regards Moo

  • Blocking access to websites with objective-C / root privileges in objective-C

    - by kvaruni
    I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I have full internet access, but I do need internet access during my working hours to get to a number of work-related websites. Clearly, this is not a permanent block, but only helps me to focus whenever I find myself wandering a bit too much. At the moment, I am using a Unix script that is called via AppleScript to obtain Administrator permissions. It then activates a number of ipfw rules and clears those after a specific duration to restore full internet access. Simple and effective, but since I am running as a standard user, it gets cumbersome to enter my administrator password each and every time I want to go "offline". Furthermore, this is a great opportunity to learn to work with XCode and Objective-C. At the moment, everything works as expected, minus the actual blocking. I can add a number of sites in a list, specify whether or not I want to block or allow these websites and I can "start" the blocking by specifying a time until which I want to stay "offline". However, I find it hard to obtain clear information on how I can run a privileged Unix command from Objective-C. Ideally, I would like to be able to store information with respect to the Administrator account into the Keychain to use these later on, so that I can simply move into "offline" mode with the convenience of clicking a button. Even more ideally, there might be some class in Objective-C with which I can block access to some/all websites for this particular user without needing to rely on privileged Unix commands. A third possibility is in starting this program with root permissions and the reducing the permissions until I need them, but since this is a GUI application that is nested in the menu bar of OS X, the results are rather awkward and getting it to run each and every time with root permission is no easy task. Anyone who can offer me some pointers or advice? Please, no security-warnings, I am fully aware that what I want to do is a potential security threat.

  • Can I Force A ASP.Net Website to Show Time in A Specific Time Zone?

    - by KevDog
    I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch. I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).
