    - by Meko
    I am trying to save image captured from web cam with current time.Like 06.06.2010 22:29:52.jpg But compiler does not allow time format 22:20:30 .

  • Problem saving as png a SVG generated by Raphael JS in a canvas

    - by ClemDesm
    Hi fellow SOers, I'm trying to convert a SVG generated by Raphael JS (and the user, since you can drag and rotate the images). I followed this Conversion of SVG to Jpeg but still can't get it. It must be easy but I can't put my finger on what I get wrong. I got my svg in a div with #ec as id and the canvas's one is #canvas. function saveDaPicture(){ var img = document.getElementById('canvas').toDataURL("image/png"); $('body').append('<img src="'+img+'"/>'); } $('#save').click(function(){ var svg = $('#ec').html(); alert(svg); canvg('canvas', svg, {renderCallback: saveDaPicture(), ignoreMouse: true, ignoreAnimation: true}); }); The alert gives me : <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="600" height="512"> <desc>Created with Raphael</desc> <defs></defs> <image x="0" y="0" width="300" height="512" preserveAspectRatio="none" href="imageurl.jpg"></image> <rect x="168" y="275" width="52" height="70" r="0" rx="0" ry="0" fill="none" stroke="#000" stroke-dasharray="8,3" transform="rotate(21.91207728 194 310)" style="opacity: 1; display: none; " opacity="1"></rect> <circle cx="50" cy="50" r="50" fill="none" stroke="#000"></circle> <image x="358" y="10" width="39" height="138" preserveAspectRatio="none" href="imageurl2.png" style="cursor: move; "></image> <image x="397" y="10" width="99" height="153" preserveAspectRatio="none" href="imageurl3.png" style="cursor: move; "></image> <image x="184" y="286" width="10" height="10" preserveAspectRatio="none" href="imageurl4.png" style="cursor: pointer; opacity: 1; display: none; " opacity="1"></image> <image x="204" y="286" width="10" height="10" preserveAspectRatio="none" href="imageurl5.png" style="cursor: pointer; opacity: 1; display: none; " opacity="1"></image> <image x="170" y="277" width="48" height="66" preserveAspectRatio="none" href="imageurl6.png" style="cursor: move; opacity: 1; " r="50" opacity="1" transform="rotate(21.91207728 194 310)"></image> </svg> which is the xml of the svg and if I believe canvg documentation, it's good. Anyway, with this code, the variable img, which should have the converted image data, got the data of an empty png with the dimensions of the svg. The only thing I guess is that the svg generated by Raphael JS is not well formated for canvg (like, href of image should be xlink:href if I follow the W3C recommandations ) Anyone got an idea on this problem ? :D

  • saving iPhone program state with a deep UINavigationController

    - by jr
    Can someone a good way to save the program state (UINavigationController stack, etc) of an iPhone application. My application obtains a bunch of information from the network and I want to return the person back to the last screen they were on, even if it was 3 or 4 screens deep. I assume that I will need to reload the data from the network along the way as I recreate the UINavigation controllers. I don't necessarily have a problem with this. I'm thinking about maybe having my UINavigationController objects implement some type of protocol which allow me to save/set their state? I'm looking to hear from others who may have needed to implement a similar scenario and how they accomplished it. My application has a UITabbarController at the root and UINavigationController items for each tab bar item. thanks!

  • Saving a record in Authlogic table

    - by denniss
    I am using authlogic to do my authentication. The current model that serves as the authentication model is the user model. I want to add a "belongs to" relationship to user which means that I need a foreign key in the user table. Say the foreign key is called car_id in the user's model. However, for some reason, when I do u = User.find(1) u.car_id = 1 u.save! I get ActiveRecord::RecordInvalid: Validation failed: Password can't be blank My guess is that this has something to do with authlogic. I do not have validation on password on the user's model. This is the migration for the user's table. def self.up create_table :users do |t| t.string :email t.string :first_name t.string :last_name t.string :crypted_password t.string :password_salt t.string :persistence_token t.string :single_access_token t.string :perishable_token t.integer :login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.integer :failed_login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.datetime :last_request_at # optional, see Authlogic::Session::MagicColumns t.datetime :current_login_at # optional, see Authlogic::Session::MagicColumns t.datetime :last_login_at # optional, see Authlogic::Session::MagicColumns t.string :current_login_ip # optional, see Authlogic::Session::MagicColumns t.string :last_login_ip # optional, see Authlogic::Session::MagicColumns t.timestamps end end And later I added the car_id column to it. def self.up add_column :users, :user_id, :integer end Is there anyway for me to turn off this validation?

  • Saving a .xls file with fwrite

    - by kielie
    hi guys, I have to create a script that takes a mySQL table, and exports it into .XSL format, and then saves that file into a specified folder on the web host. I got it working, but now I can't seem to get it to automatically save the file to the location without prompting the user. It needs to run every day at a specified time, so it can save the previous days leads into a .XSL file on the web host. Here is the code: <?php // DB TABLE Exporter // // How to use: // // Place this file in a safe place, edit the info just below here // browse to the file, enjoy! // CHANGE THIS STUFF FOR WHAT YOU NEED TO DO $dbhost = "-"; $dbuser = "-"; $dbpass = "-"; $dbname = "-"; $dbtable = "-"; // END CHANGING STUFF $cdate = date("Y-m-d"); // get current date // first thing that we are going to do is make some functions for writing out // and excel file. These functions do some hex writing and to be honest I got // them from some where else but hey it works so I am not going to question it // just reuse // This one makes the beginning of the xls file function xlsBOF() { echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0); return; } // This one makes the end of the xls file function xlsEOF() { echo pack("ss", 0x0A, 0x00); return; } // this will write text in the cell you specify function xlsWriteLabel($Row, $Col, $Value ) { $L = strlen($Value); echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L); echo $Value; return; } // make the connection an DB query $dbc = mysql_connect( $dbhost , $dbuser , $dbpass ) or die( mysql_error() ); mysql_select_db( $dbname ); $q = "SELECT * FROM ".$dbtable." WHERE date ='$cdate'"; $qr = mysql_query( $q ) or die( mysql_error() ); // Ok now we are going to send some headers so that this // thing that we are going make comes out of browser // as an xls file. // header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); //this line is important its makes the file name header("Content-Disposition: attachment;filename=export_".$dbtable.".xls "); header("Content-Transfer-Encoding: binary "); // start the file xlsBOF(); // these will be used for keeping things in order. $col = 0; $row = 0; // This tells us that we are on the first row $first = true; while( $qrow = mysql_fetch_assoc( $qr ) ) { // Ok we are on the first row // lets make some headers of sorts if( $first ) { foreach( $qrow as $k => $v ) { // take the key and make label // make it uppper case and replace _ with ' ' xlsWriteLabel( $row, $col, strtoupper( ereg_replace( "_" , " " , $k ) ) ); $col++; } // prepare for the first real data row $col = 0; $row++; $first = false; } // go through the data foreach( $qrow as $k => $v ) { // write it out xlsWriteLabel( $row, $col, $v ); $col++; } // reset col and goto next row $col = 0; $row++; } xlsEOF(); exit(); ?> I tried using, fwrite to accomplish this, but it didn't seem to go very well, I removed the header information too, but nothing worked. Here is the original code, as I found it, any help would be greatly appreciated. :-) Thanx in advance. :-)

  • Saving data so it can be loaded locally

    - by Thomas Joos
    hi guys, i'm working on iphone application which needs to run offline at an exhibition. It should present data, stored local because there is no internet at the booth. Still, to easily have content updates it should be able to update it's content once connected to internet. It's quite some data ( around 300 full lines of text ) and I want it to be loaded, stored and visualized as optimized as possible. What's the best way to load in content once connected and how should I store it on the device?

  • Updating a TableView with a WebService and Saving to CoreData

    - by jcady
    I am working on a project where I have a table view that is currently updated via a web request that returns XML. I implemented -(int)numberOfRowsInTableView:(NSTableView*)tv and -(id)tableView:(NSTableView *)tv objectValueForTableColumn:(NSTableColumn*)tableColumn row:(int)row in my XML parsing class, and have the table updated with the data that is pulled down from the server. I want to save the data that is pulled down using Core Data, so that the table can be saved/loaded. Then later on application start when the web request is made, it will only add data that is not already present. (The XML is sorted by release date, so later I will check to see which release dates are not loaded up from the Core Data store, and only load newer entries.) How would I go about implementing this? I am a very new Cocoa developer, but have gone through the entire Hillegass book. Thanks so much.

  • Saving data to server with user accounts.

    - by AKRamkumar
    Ok, so for an app I am making, I want the user to be able to save data online. On my website, I will provide a web server with tables of UserName/Password/SaveData. How can I do this without crashing the server load? How can I guarantee security ? Is there a Design Pattern for this?Is there a better way of doing this? This is going to be a free application, available to the public and I would like for their settings to be available, no matter the computer they are using. Is there a better way of doing this? I am using MEF for plugins so is there a way I can save plugin data as well?

  • Saving a "project"-type document (containing sub-documents)

    - by andyvn22
    I'm trying to create a "project"-like document, in that it contains subdocuments in a specified directory. I'd like a brand new save of a document to set up that directory with appropriate subdirectories. I'd like a "Save As" to copy all those subdirectories and any files within them to the new location. But I'd like a "Save" to only update certain data files and (of course) not overwrite all the subdocuments! What's the "safe" way to do this? I tried keeping track of the file's location in my document, and checking to see if it was the same or different than the save location, but it feels messy, and I'm worried that Apple is doing something behind the scenes that will make this direct URL-to-URL comparison fail in some circumstances. Is there a standard way to do something like this?

  • Saving generated .wav file to server with PHP

    - by bionicOnion
    I am developing a website where users can compose their own music, and the site will generate a .wav file for their creation. This is working correctly (inasmuch as I can play it on the page). However, I would like to save this file to the server to be listened to/downloaded at a later time, and the saved version of the file can no longer be opened and played by the HTML audio tag. What, if anything, must I put into the file besides the file besides the raw data? Instead of setting the src attribute of the audio tag to the location of the file, will I actually need to open it and generate a URI?

  • Saving gzipped string into Sqlite3 via Rails throws unrecognized token error

  • Saving complex aggregates using Repository Pattern

    - by Kevin Lawrence
    We have a complex aggregate (sensitive names obfuscated for confidentiality reasons). The root, R, is composed of collections of Ms, As, Cs, Ss. Ms have collections of other low-level details. etc etc R really is an aggregate (no fair suggesting we split it!) We use lazy loading to retrieve the details. No problem there. But we are struggling a little with how to save such a complex aggregate. From the caller's point of view: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r); Our competing solutions are: Dirty flags Each entity in the aggregate in the aggregate has a dirty flag. The save() method in the repository walks the tree looking for dirty objects and saves them. Deletes and adds are a little trickier - especially with lazy-loading - but doable. Event listener accumulates changes. Repository subscribes a listener to changes and accumulates events. When save is called, the repository grabs all the change events and writes them to the DB. Give up on repository pattern. Implement overloaded save methods to save the parts of the aggregate separately. The original example would become: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r.Ps); repository.save(r.Cs); repository.save(r.Ms); (or worse) Advice please! What should we do?

  • Saving multiple objects in a single call in rails

    - by CaptnCraig
    I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?

  • Saving "heavy" figure to PDF in MATLAB - rendering problem

    - by yuk
    I generate a figure in MATLAB with lot amount of points (100000+) and want to save it into a PDF file. With zbuffer or painters renderer I've got very large and slowly opened file (over 4 Mb) - all points are in vector format. Using OpenGL renderer rasterize the figure in PDF, ok for the plot, but not good for text labels. The file size is about 150 Kb. Try this simplified code, for example: x=linspace(1,10,100000); y=sin(x)+randn(size(x)); plot(x,y,'.') set(gcf,'Renderer','zbuffer') print -dpdf -r300 testpdf_zb set(gcf,'Renderer','painters') print -dpdf -r300 testpdf_pa set(gcf,'Renderer','opengl') print -dpdf -r300 testpdf_op The actual figure is much more complex with several axes and different types of plots. Is there a way to rasterize the figure, but keep text labels as vectors? Another problem with OpenGL is that is does not work in terminal mode (-nosplash -nodesktop) under Mac OSX. Looks like OpenGL is not supported. I have to use terminal mode for automation. The MATLAB version I run is 2007b. Mac OSX server 10.4.

  • Android - Lifecycle and saving an Instance State questions

    - by The Salt
    So within my application is a form for creating a new user, with relevant details and information about the user. There's no problems there, it's just what happens when the user leaves the activity without pressing the confirm button. Here's what I want to do: If the user presses the back button, attempt to save all the data to the database and inform the user. If the activity is interrupted (ie by a phone call), save all the data into a temporary location so when the activity is at the top of the stack again, nothing appears to have changed (but the data still hasn't yet been saved to the database). If the activity gets killed for more resources when in the background, do the same as point 2 above (ie when the activity is started again, it appears that nothing has changed). If the whole application is started again (by clicking on the icon again) and there is temporary data stored from either points 2 or 3 above, navigate to the "create user" activity and display data as if nothings changed. Here's how I'm currently trying to do it: Use onDestroy() and isFinishing() functions to find when the activity is being killed, to cover point 1 above (to then try and save all data). Save all data with onSaveInstanceState into a bundle (to cover point 2 above) Does the bundle created with onSaveInstanceState survive the activity being killed for more resources, so when its recreated the previous state can be retrieved (as in point 3 above)? No idea how to implement point 4. Any help would be massively appreciated. Cheers!

  • Java 1.5.0_16 corrupted colours when saving jpg image

    - by Coder
    Hi, i have a loaded image from disk (stored as a BufferedImage), which i display correctly on a JPanel but when i try to re-save this image using the command below, the image is saved in a reddish hue. ImageIO.write(image, "jpg", fileName); Note! image is a BufferedImage and fileName is a File object pointing to the filename that will be saved which end in ".jpg". I have read that there were problems with ImageIO methods in earlier JDKs but i'm not on one of those versions as far as i could find. What i am looking for is a way to fix this issue without updating the JDK, however having said that i would still like to know in what JDK this issue was fixed in (if it indeed is still a bug with the JDK i'm using). Thanks.

  • Saving HttpResponse/Request to file system

    - by chrisjlong
    Here is my scenario. User fills out this large page which is dynamically created based off DB values. Those values can change. When the user fills out the page and hits submit we want to save a copy of the page as html on the server, this way if the text or wording changes, when they go back to view their posted information, it is historically accurate. So I basically need to do this protected void buttonSave_Click(object sender, EventArgs e) { //collect information into an object to save it in the db bool result = BusinessLogic.Save(myBusinessObject); if (result) //!!! Here is where I need to save this page as an html file on my servers IFS!!!! else //whatever Response.Redirect("~/SomeOtherPage.aspx"); } Any help is greatly apprciated. Also I CANNOT just request the data from the url because query string parameters are a big no no in this case. The key to pull the database info up (at its highest level) is all in session so I cant just request a url and save it. Thanks!

  • How to load object after saving with encodeWithCoder?

    EDIT_002: Further rewrite: if I save using the method below how would the method to load it back in look?
