  • Convert input to integer before save in rails

    - by Micke
    Hello, i have a set of select inputs representing a users birthday: birthyear, birthmonth and birthday. And i want to validate birthyear like this: validates_inclusion_of :birthyear, :in => Date.today.year-50..Date.today.year-12 So the user can be at least 12 years but at most 50 years when they are registering. But my problem is that the variable from the input is a string and not an integer. So how can i convert the input to an integer? or is there any easier way to check the users age? Thanks, Micke

  • Save options selected in AlertDialog spawned from ItemizedOverlay onTap method

    - by ahsteele
    In the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class. In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on. That said I am unsure if utilizing an AlertDialog in this manner is the right approach and open to other suggestions. protected boolean onTap(int index) { OverlayItem item = _overlays.get(index); final CharSequence[] items = { "WiFi", "BlueTooth" }; final boolean[] checked = { false, false }; AlertDialog.Builder builder = new AlertDialog.Builder(_context); builder.setTitle(item.getTitle()); builder.setMultiChoiceItems(items, checked, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int item, boolean isChecked) { // for now just show that the user touched an option Toast.makeText(_context, items[item], Toast.LENGTH_SHORT).show(); } }); builder.setPositiveButton("Okay", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { // should I be examining what was checked here? dialog.dismiss(); } }); builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); return true; }

  • EF 4.0 : Save Changes Retry Logic

    - by BGR
    Hi, I would like to implement an application wide retry system for all entity SaveChanges method calls. Technologies: Entity framework 4.0 .Net 4.0 namespace Sample.Data.Store.Entities { public partial class StoreDB { public override int SaveChanges(System.Data.Objects.SaveOptions options) { for (Int32 attempt = 1; ; ) { try { return base.SaveChanges(options); } catch (SqlException sqlException) { // Increment Trys attempt++; // Find Maximum Trys Int32 maxRetryCount = 5; // Throw Error if we have reach the maximum number of retries if (attempt == maxRetryCount) throw; // Determine if we should retry or abort. if (!RetryLitmus(sqlException)) throw; else Thread.Sleep(ConnectionRetryWaitSeconds(attempt)); } } } static Int32 ConnectionRetryWaitSeconds(Int32 attempt) { Int32 connectionRetryWaitSeconds = 2000; // Backoff Throttling connectionRetryWaitSeconds = connectionRetryWaitSeconds * (Int32)Math.Pow(2, attempt); return (connectionRetryWaitSeconds); } /// <summary> /// Determine from the exception if the execution /// of the connection should Be attempted again /// </summary> /// <param name="exception">Generic Exception</param> /// <returns>True if a a retry is needed, false if not</returns> static Boolean RetryLitmus(SqlException sqlException) { switch (sqlException.Number) { // The service has encountered an error // processing your request. Please try again. // Error code %d. case 40197: // The service is currently busy. Retry // the request after 10 seconds. Code: %d. case 40501: //A transport-level error has occurred when // receiving results from the server. (provider: // TCP Provider, error: 0 - An established connection // was aborted by the software in your host machine.) case 10053: return (true); } return (false); } } } The problem: How can I run the StoreDB.SaveChanges to retry on a new DB context after an error occured? Something simular to Detach/Attach might come in handy. Thanks in advance! Bart

  • How to get image's coordinate on JPanel

    - by Jessy
    This question is related to my previous question http://stackoverflow.com/questions/2376027/how-to-generate-cartesian-coordinate-x-y-from-gridbaglayout I have successfully get the coordinate of each pictures, however when I checked the coordinate through (System.out.println) and the placement of the images on the screen, it seems to be wrong. e.g. if on the screen it was obvious that the x point of the first picture is on cell 2 which is on coordinate of 20, but the program shows x=1. Here is part of the code: public Grid (){ setPreferredSize(new Dimension(600,600)); .... setLayout(new GridBagLayout()); GridBagConstraints gc = new GridBagConstraints(); gc.weightx = 1d; gc.weighty = 1d; gc.insets = new Insets(0, 0, 0, 0);//top, left, bottom, and right gc.fill = GridBagConstraints.BOTH; JLabel[][] label = new JLabel[ROWS][COLS]; Random rand = new Random(); // fill the panel with labels for (int i=0;i<IMAGES;i++){ ImageIcon icon = createImageIcon("myPics.jpg"); int r, c; do{ //pick random cell which is empty r = (int)Math.floor(Math.random() * ROWS); c = (int)Math.floor(Math.random() * COLS); } while (label[r][c]!=null); //randomly scale the images int x = rand.nextInt(50)+30; int y = rand.nextInt(50)+30; Image image = icon.getImage().getScaledInstance(x,y, Image.SCALE_SMOOTH); icon.setImage(image); JLabel lbl = new JLabel(icon); // Instantiate GUI components gc.gridx = r; gc.gridy = c; add(lbl, gc); //add(component, constraintObj); label[r][c] = lbl; } I checked the coordinate through this code: Component[] components = getComponents(); for (Component component : components) { System.out.println(component.getBounds()); }

  • Can not read and save a number from/into an .plist

  • Where specifically do UIImageWriteToSavePhotosAlbum or UISaveVideoAtPathToSavedPhotosAlbum save thei

    - by Chris Markle
    Simple question I think and I'll be trying ot myself to see... When people talk about using UIImageWriteToSavePhotosAlbum or UISaveVideoAtPathToSavedPhotosAlbum is the "saved photos album" the "Camera Roll" or the "Photo Library" (or something else either than these two) that I see in the Photo Albums application? I don't think the doc makes it super-explicit as to which it is...

  • Asynchronous Image loading in certain custom UITableViewCells

    - by Dan
    So, I'm sure that this issue has been brought up before, but I haven't quite seen a solution for my specific problem. What I'm doing is loading a group of custom UITableViewCell's that are drawn using Loren Brichter's solution, each cell has some content, an icon (representing the user) that is asynchronously loaded into it, and a few other things. Eventually, I'm hoping to add support for images. Not every cell has an image, so in the creation of the cell, it determines if an image is required to be loaded and drawn into the cell. My problem is that I don't know how I can do that while keeping the image loaded asynchronously - with not every cell having the need to load an image (like needed with the icon) I'm not sure how to keep it in order when an cell is thrown off screen and re-rendered when the user scrolls over it. Each cell draws it content from an NSArray containing a custom object called FeedItem. All I'm really looking for is some sort of solution or idea to help me because right now I am at a loss. Thanks guys, I will appreciate the help.

  • Why does appending "" to a String save memory?

    - by hsmit
    I used a variable with a lot of data in it, say String data. I wanted to use a small part of this string in the following way: this.smallpart = data.substring(12,18); After some hours of debugging (with a memory visualizer) I found out that the objects field smallpart remembered all the data from data, although it only contained the substring. When I changed the code into: this.smallpart = data.substring(12,18)+""; ..the problem was solved! Now my application uses very little memory now! How is that possible? Can anyone explain this? I think this.smallpart kept referencing towards data, but why? UPDATE: How can I clear the big String then? Will data = new String(data.substring(0,100)) do the thing?

  • How do you save compare options in Visual Studio 2010 > SQL 2012 Database Project

    - by profMamba
    Been using the new SQL 2012 Data Tools SQL Server Database Project in VS 2010. Every time we do a schema compare we have to set the options for the current compare. This does not seem to be tied back to the global compare options you can set in Tools Options. Does anybody know where to set the 'new' global compare options. NOTE: This is the new SQL 2012 compare from Data Tools, and not the old 2005/2008 compare that comes standard with Studio 2010.

  • Adding a dynamic image to UITable View Cell

    - by Graeme
    Hi, I have a table in which I want a dynamic image to load in at the left-hand side. The table needs to use an IF statement to select the appropriate image from the "Resources" folder, and needs to be based upon [dog types]. The [dog types] is extracted from an RSS feed, and so the image in the table cell needs to match the each cell's [dog types] tag. Update: See code below for what I'm looking to do (only below it's for earthquakes, for me its pictures of dogs). I suspect I need to use - (UIImage *)imageForTypes:(NSString *)types { to do such a thing. Thanks. Updated code: This is for Apple's Earthquake sample but does exactly what I need to do. It matches images to the severity (2.0, 3.0, 4.0, 5.0 etc.) of every earthquake to the magnitude. - (UIImage *)imageForMagnitude:(CGFloat)magnitude { if (magnitude >= 5.0) { return [UIImage imageNamed:@"5.0.png"]; } if (magnitude >= 4.0) { return [UIImage imageNamed:@"4.0.png"]; } if (magnitude >= 3.0) { return [UIImage imageNamed:@"3.0.png"]; } if (magnitude >= 2.0) { return [UIImage imageNamed:@"2.0.png"]; } return nil; } and under - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath magnitudeImage.image = [self imageForMagnitude:earthquake.magnitude];

  • Two PickerViews in save View issue?

    - by NextRev
    I'm trying to have 2 pickerviews in the same view. It works except for two things. If one pickerview has more rows than the other the app crashes when picking an item from the pickerview with more items. Also I created an NSLog for the pickerviews and the console shows that I'm picking two items at once when in fact i'm only dealing with one pickerview. I know it sounds a bit confusing but I'm including all the code.

  • mysql image disable print download

    - by Vish
    Hi, We use a Flex AIR client and a WAMP server. Tiff images are stored in MySQL. Currently, I can download the image from AIR client and it prompts for a download dialog. Things are fine till this point. We got a new requirement. Requirement is that only some users can print the image which gets downloaded. For other users, they should not be able to print the tiff image. Wondering how to accomplish this. One idea, not sure if its efficient, is to convert the image requested to pdf at the server side, disable print option there(hope there are API's available) and send back the pdf. Please let me know btter ideas. Also, is there a way to prevent file download dialog from popping up everytime the file is requested for download? Can we just get the file stream to the client and manipulate it to open with a particular viewer or write it to pdf... Please help.

  • save and restore state of a tab bar controller

    - by phunehehe
    I have an application that has a UITabBarController with two tabs, each having its own navigation controller. Now I want to store the state of the application when the user closes it, so that when the user relauches the application will show the same place as the last time before it was closed. So, in applicationWillTerminate: I have [NSKeyedArchiver archiveRootObject:tabBarController toFile:@"lastVisitedTab"]; Then, in applicationDidFinishLaunching: I have UITabBarController *last= (UITabBarController *)[NSKeyedUnarchiver unarchiveObjectWithFile:@"lastVisitedTab"]; if (last) tabBarController = [last retain]; I also have an extension to UIImage to make it compliant to NSCoding. However, this doesn't work, as the state is not preserved. The first tab gets selected all the time, and no navigation is preserved either. Can someone tell me what's wrong, or show me how to do it correctly?

  • Unable to save to wincache from cakePHP shell

    - by Phillaf
    I'm trying to retrieve the weather from wunderground.com through their API, and store it in wincache. For testing purposes I made this function in the News model: public function updateWeather(){ $results = file_get_contents('http://api.wunderground.com/api/**api_key**/conditions/q/CA/Montreal.json'); $results = json_decode($results); return Cache::write('weather', $results); } It works fine when I call this from the controller. However, I can't figure why that same function doesn't work when called from the console. I made this shell in order to eventually add this to windows task scheduler. class WeatherShell extends AppShell { public $uses = array('News'); public function main() { $this->News->updateWeather(); } } When running this, I see that $results is correctly populated. I get 'true' from Cache::write(), however, I get 'false' when trying to read. What subtlety am I missing?

  • Save has_and_belongs_to_many link in basic RoR app

    I try to learn the has_and_belongs_to_many relationship between my 2 fresh new and simple models Product and Author, where a Product can have many authors and where author can have a lots of products. I wrote this : class Author < ActiveRecord::Base has_and_belongs_to_many :products end class Product < ActiveRecord::Base has_and_belongs_to_many :authors end In the partial form of view for the products, I have : <p>Products</p> <%= collection_select(:product, :author_ids, @authors, :id, :name, :prompt => " ", :multiple => true) %> but when I hit the update button, I get this strange message I can't resolve myself : NoMethodError in ProductsController#update undefined method `reject' for "1":String Rails.root: /home/stephane/www/HABTM Application Trace | Framework Trace | Full Trace app/controllers/products_controller.rb:63:in block in update' app/controllers/products_controller.rb:62:inupdate' Request Parameters: {"utf8"="✓", "_method"="put", "authenticity_token"="2GlTssOFjTVZ9BikrIFgx22cdTOIJuAB70liYhhLf+4=", "product"={"title"="Le trésor des Templiers", "original_title"="", "number"="1", "added_by"="", "author_ids"="1"}, "commit"="Update Product", "id"="1"} What's wrong ?

  • webcam refreshing image in iframe not working IE

    - by Nix
    I'm trying to show images from this webcam http://regacam.usz.ch/cgi-bin/guestimage.html on an html page by putting an iframe in pointing to another page that has an image tag in it. But it isn't working in IE (I just see a little cross where the image should be), Firefox is ok. Here the page with the image in: <html> <head> <meta http-euqiv="refresh" content="5"> </head> <body> <img src="http://regacam.usz.ch/cgi-bin/faststream.jpg?stream=full&fps=0.01667&rand=295543" width="200" height="150"/> </body> <html> and the iframe: <div id="rightcontainer"> <iframe id="rightframe" src="zurich.html" name="content" frameborder="0"></iframe> </div> I tried a different webcam elsewhere and that works ok in both browsers. Is there something odd about the one in my example? I got the link in src by right-clicking and copying the image location - is that the right way to go about it?

  • how to tile 3D mesh with image brush in XAML

    - by MC9000
    I have a 2D square in a ViewPort3D that I want to do a tiling of an image (like a checkerboard or flooring with "tiles" effect). I've created an image brush (the image is 50x50 pixels, the surface 250x550 pixels) and a viewport (trying to follow MS's site - though their example is for 2D), but only 1 of the colors in the "tile" image shows up and no tiling is seen. I can't find a single example on the Internet and MS's site has no info (that I can find) on 3D XAML anywhere, so I'm stumped as how to actually do this. <Viewport3D> <Viewport3D.Camera> <PerspectiveCamera Position="125,790,120" LookDirection="0,-.7,-0.25" UpDirection="0,0,1" /> </Viewport3D.Camera> <ModelVisual3D> <ModelVisual3D.Content> <Model3DGroup> <AmbientLight Color="white" /> <GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D Positions="0,0,0 250,0,0 250,550,0 0,550,0 " TriangleIndices="0 1 3 1 2 3 "/> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <DiffuseMaterial> <DiffuseMaterial.Brush> <ImageBrush ViewportUnits="Absolute" TileMode="Tile" ImageSource="testsquare.gif" Viewport="0,0,50,50" Stretch="None" ViewboxUnits="Absolute" /> </DiffuseMaterial.Brush> </DiffuseMaterial> </GeometryModel3D.Material> </GeometryModel3D> </Model3DGroup> </ModelVisual3D.Content> </ModelVisual3D> </Viewport3D>

  • Save entity with entity framework

    - by Michel
    Hi, I'm saving entities/records with the EF, but i'm curious if there is another way of doing it. I receive a class from a MVC controller method, so basicly i have all the info: the class's properties, including the primary key. Without EF i would do a Sql update (update table set a=b, c=d where id = 5), but with EF i got no further than this: Get an object with ID of 5 Update the (existing) object with the new object Submitchanges. What bothers me is that i have to get the object from the database first, where i have all the info to do an update statement. Is there another way of doing this?

  • Cursor image to the center on mouseout

    - by Milla
    Hi all! I'm a real noobie with flash and I was wondering if somebody could help me with this one. I have this actionsript 3 code, where the cursor image "ball_mc" follows the mouse's position with a slight delay: stage.addEventListener(Event.ENTER_FRAME,followBall); function followBall(event:Event):void { var dx:int = ball_mc.x - mouseX; var dy:int = ball_mc.y - mouseY; ball_mc.x -= dx / 5; ball_mc.y -= dy /5; } 1) How can I get the cursor image automatically return to the center of the stage on mouseout? As of now, it stays at the position where the mouse leaves the stage. 2) How can I reverse the movement of the mouse? So that when I, for example, move mouse to the right, the cursor image would move to the left? And when moving the mouse up, the image would go down. The stage is 800 x 250 pixels, in case that makes any difference.
