  • How to draw multiple line text to uiimageview iphone?

    - by Hu?nh Phong
    I have UITextView for text, after user press DONE, I convert text to UIImageView and show it. It works with one line of text very good, and Screenshot 1 . But if user types two lines, or more: the result is still one line??? Screenshot 2 I want to display two or more lines in UIimageView Can anybody help me! Thank you very much! Here is my code: -(UIImage *)convertTextToImage : (ObjectText *) objT; { UIGraphicsBeginImageContext(CGSizeMake(([objT.content sizeWithFont:objT.font].width+10), ([objT.content sizeWithFont:objT.font].height+10))); [[objT getcolor] set]; [objT.content drawAtPoint:CGPointMake(5, 5) withFont:objT.font]; UIImage *result = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return result; }

  • How to build this encryption system that allows multiple users/objects.

    - by Patrick
    Hello! I am trying to figure out how to create an optimal solution for my project. I made this simple picture in Photoshop to try to illustrate the problem and how i want it (if possible). Illustrative image Ill also try to explain it based on the picture. First off we have a couple of objects to the left, these objects all get encrypted with their own encryption key (EKey on the picture) and then stored in the database. On the other side we have different users placed into roles (one user can be in a lot of roles) and the roles are associated with different objects. So one person only has access the to the objects that the role provides. So for instance Role A might have access to Object A and B. Role B have access only to Object C and Role C have access to all objects. Nothing strange in that, right? Different roles have different objects that they can access. Now to the problem part. Each user has to login with his/her username/password and then he/she gets access to the objects that his/her roles provide. All the objects are encrypted so she needs to get a decryption key somehow. I don't want to store the encryption key as a text string on the server. It should be, if possible, decrypted using the users password (along with the role) or similar. That way you have to be a user on the server in order to decrypt an object an to work with it. I was thinking about making a public/private key encryption system, but i am kinda stuck on how to give the different users the decryption key to the objects. Since i need to be able to move users to and from roles, add new users, add new roles and create/delete objects. There will be one administrator that then adds some data to allow the users in that role to get the decryption key to decrypt the object. Nothing is static and i am trying to get a picture of how this can be built or if there is a far better solution. The only criteria are: -Encrypted objects. -Decryption key should not be stored as text. -Different users have access to different objects. -Does NOT have to have roles.

  • [Rails3] How to do multiple many to many relationships between the same two tables.

    - by Kurt
    Hi. I have a model of a club where I want to model the two entities Meeting and Member. There are actually two many-to-many relationships between these entities though, as for any meeting a Member can either be a Speaker or a Guest. Now I am an OO thinker, so would normally just create the two classes and each one would just have two arrays of the other inside, but rails is making me think a bit more data centric here, so I realise I need to break these M2M relationships up with join tables Speakers and Guests which I have done, but now I am having trouble describing the relationships in the models. The two join table models both have "belongs_to :meeting" and "belongs_to :member" and I think that should be sufficient. I am not however sure about the Meeting and Member models though. Each one has "has_many :guests" and "has_many: speakers" but I am not sure if I also want to go: has_many :members, :through = :guests has_many :members, :through = :speakers But I suspect that this is like declaring two "members" that will clash. I also thought about: has_many :guests, :through = :guests has_many :speakers, :through = :speakers Does that make sense? How would ActiveRecord know that they are in fact Members? I have found heaps of examples of polymorphic m2m relationships and m2m relationships where 1 table references itself, but no good examples to help me mode this situation where two separate tables have two different m2m relationships. Anyone got any tips?

  • How to deal with multiple screensizes + dynamic controls in Android?

    - by chobo2
    Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

  • How do I implement jQuery image cycle loops on rollover for multiple thumbnail sets on a page?

    - by Kendrick Ledet
    Here is the Javascript I currently have <script type="text/javascript"> $(function() { $('.slideshow').hover( function() { $('.slides').cycle('resume'); }, function() { $('.slides').cycle('pause'); } ); $('.slides').cycle({ fx: 'fade', speed: .3, timeout: 280, next: '#next', prev: '#prev' }).cycle("pause"); }); </script> It works; but the thing is it works for all thumbnail sets on the page, and whenever I mouseover on one set of images, every other set of images loops as well. I do see that this is because I'm targeting classes, but my jQuery experience is quite limited so I have no idea how to only target a single instance of each class without effecting the others, and I can't go in and hardcode id's because my thumbnails and amount of videos on each page are determined dynamically via this Django template. http://pastebin.com/nf42bSAx I would greatly appreciate any help, as this is essential for my project (open source media platform). Thank you.

  • Can you have a web application project produce multiple DLLS?

    - by chris
    I have a VS 2008 web application project that is getting large. My structure looks like: - WebRoot - Common/ - Foo/ - Bar/ - Baz/ so I end up with a single Webroot.dll that contains the code for common, foo, bar, and baz. Is it possible to set it so that I end up with common/ in webroot.dll, and code in foo ends up in foo.dll, bar in bar.dll, etc? Update: A couple of suggestions to move some stuff into class libraries. We already have a dozen or so separate class library projects as part of the solution; Foo, Bar and Baz contain nothing but web forms and the associated code-behinds, so moving them into separate class library projects is not feasible.

  • scala coalesces multiple function call parameters into a Tuple -- can this be disabled?

    - by landon9720
    This is a troublesome violation of type safety in my project, so I'm looking for a way to disable it. It seems that if a function takes an AnyRef (or a java.lang.Object), you can call the function with any combination of parameters, and Scala will coalesce the parameters into a Tuple object and invoke the function. In my case the function isn't expecting a Tuple, and fails at runtime. I would expect this situation to be caught at compile time. object WhyTuple { def main(args: Array[String]): Unit = { fooIt("foo", "bar") } def fooIt(o: AnyRef) { println(o.toString) } } Output: (foo,bar)

  • User Interface. Multiple select with priority.

    - by Andrew Florko
    I'm designing user interface and want to ask your advises how to make it more user-friendly. Please tell any suggestions and if you have ever seen implementation of something familiar please share the link. University. There are 40+ specialities grouped into 5 faculties. User choose several he is interested in and than orders them by priority. For example I am interested in "programming microcontrollers", "system analysis" and "experimental physic". I must find them quickly in "programming faculty", select them and then order - what I prefer most and what I prefer less then others I select. Any ideas welcome :)

    - by Chilln
    Hey, im using a connection to a server in my php script, opened with fsockopen() and i want it to share between different pages so i serialized it and saved it in a session variable but it seems that that ia a bad idea because when i do this nothing happens... Not even an error. The problem is that this connection requires a handshake so i cant reconnect everytime Another question, whats the timeout of fsockopen or does the connection stay alive if the. original php script which called it is closed?

  • jQuery: using hover to roll-over multiple images at once.

    - by WillKop
    I have a small problem, but I'm a bit stumped. I am using the following code to do rollovers on my webpage $("#mylink1 img").hover( function() { this.src = this.src.replace("_off","_on"); }, function() { this.src = this.src.replace("_on","_off"); } ); This works great for individual images, but I would like to roll over one of them and have the the other one change as well. <a id="mylink1" href="about.cfm"><img src="images/Home_top_navs/aboutus_manage_off.gif" /></a> <a id="mylink1" href="about.cfm"><img src="images/Home_top_navs/aboutus_nav2_off.gif" /></a> Any help would be appreciated! Thank you!

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

  • Will an IO blocked process show 100% CPU utilization in 'top' output?

    - by Alex Stoddard
    I have an analysis that can be parallelized over a different number of processes. It is expected that things will be both IO and CPU intensive (very high throughput short-read DNA alignment if anyone is curious.) The system running this is a 48 core linux server. The question is how to determine the optimum number of processes such that total throughput is maximized. At some point the processes will presumably become IO bound such that adding more processes will be of no benefit and possibly detrimental. Can I tell from standard system monitoring tools when that point has been reached? Would the output of top (or maybe a different tool) enable me to distinguish between a IO bound and CPU bound process? I am suspicious that a process blocked on IO might still show 100% CPU utilization.

  • How to pass multiple PHP variables to a jQuery function?

    - by jcpeden
    I'm working on a Wordpress plugin. I need to pass plugin directories (that can change depending on an individual's installation) to a jquery function. What is the best way of doing this? The version of the plugin that I can to work on had included all the javascript in the PHP file so the functions were parsed along with the rest of the content before being rendered in a browser. I'm looking at AJAX but I think it might be more complicated than I need. I can get away with just two variables in this case (directories, nothing set by the user). As I've read its good practice, I'm trying to keep the js and php separate. When the plugin initializes, it call the js file: //Wordpress calls the .js when the plugin loads wp_enqueue_script( 'wp-backitup-funtions', plugin_dir_url( __FILE__ ) . 'js/wp-backitup.js', array( 'jquery' ) ); Then I'm in the .js file and need to figure out how to generate the following variables: dir = '<?php echo content_url() ."/plugins"; ?>'; dir = '<?php echo content_url() ."/themes"; ?>'; dir = '<?php echo content_url() ."/uploads"; ?>'; And run the parse the following requests: xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/includes/wp-backitup-restore.php'); ?>",true); xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/includes/wp-backitup-start.php'); ?>",true); xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/wp-backitup-directory.php'); ?>",true); xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/wp-backitup-db.php'); ?>",true); window.location = "<?php echo plugins_url() .'/wp-backitup/backitup-project.zip'); ?>"; xmlhttp.open("POST","<?php echo plugins_url() .'/wp-backitup/wp-backitup-delete.php'); ?>",true); Content URL and Plugins URL differ only by /plugins/ so if I was hard pressed, I would only really need to make a single PHP request and then bring this into the JS.

What kind of field should it be, and how should I read/write to it?

  • Is there a point to have multiple VS projects for an ASP.NET MVC application?

    - by mare
    I'm developing MVC application where I currently have 3 projects in solution. Core (it is supposed to be for Repositories, Business Classes, Models, HttpModules, HttpFilters, Settings, etc.) Data access (Data provider, for instance SqlDataProvider for working with SQL Server datastore - implements Repository interfaces, XmlDataProvider - also implements Repository interfaces but for local XML files as datastore) ASP.NET MVC project (all the typical stuff, UI, controllers, content, scripts, resources and helpers). I have no Models in my ASP.NET MVC project. I've just run into a problem because of that coz I want to use the new DataAnnotation feature in MVC 2 on my Bussiness class, which are, as said in Core, however I have I want to be able to localize the error messages. This where my problem starts. I cannot use my Resources from MVC project in Core. The MVC project references Core and it cannot be vice-versa. My options as I see them are: 1) Move Resources out but this would require correcting a whole bunch of Views and Controllers where I reference them, 2) Make a complete restructure of my app What are your thoughts on this? Also, Should I just move everything business related into Models folder in MVC project?? Does it even make any sense to have it structured like that, because we can just make subfolders for everything under MVC project? The whole Core library is not intended to ever be used for anything else, so there actually no point of compiling it to a separate DLL. Suggestions appreciated.
