  • Adding an additional link button to a form (using form->create)

    - by cloudhead
    I have recently been assigned a CSS & design project that's in a CakePHP environment and would like to know if I can add an additional button to the form, for a "sign up" link. The form is currently: echo $form->create('User', array('action' => 'login')); echo $form->inputs(array( 'legend' => 'Please log in:', 'username', 'password')); echo $form->end('Login'); I would like to inject a button that goes to an action of 'register', preferably after the "Login" button, on the same line, like this: username: [ ] password: [ ] [Log In] [Register] I have everything but the 'register' button. Is this possible using the 'automagic' form creation? Thank you.

  • How to create an image from canvas data?

    - by Jakub Hampl
    In my application I am trying to save an arbitrary part of a rendered HTML canvas to an image file. In my Javascript I call ctx.getImageData(x, y, w, h) and pass the resulting object to my macruby code (though if you know a solution in objc I am also very interested). There I'm trying to create a NSBitmapImageRep object so that I can then save to an image format the user desires. This is my code so far (the function gets a WebScriptObject as it's argument): def setimagedata(d) w = d.valueForKey("width").to_i h = d.valueForKey("height").to_i data = Pointer.new(:char, d.valueForKey("data").valueForKey("length").to_i) d.valueForKey("data").valueForKey("length").to_i.times do |i| data[i] = d.valueForKey("data").webScriptValueAtIndex(i).to_i end puts "data complete" # get's called @exported_image = NSBitmapImageRep.alloc.initWithBitmapDataPlanes(data, pixelsWide: w, pixelsHigh:h, bitsPerSample: 32, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: NSCalibratedRGBColorSpace, bitmapFormat: NSAlphaNonpremultipliedBitmapFormat, bytesPerRow: 0, bitsPerPixel: 0) puts "done" # doesn't get called end The code doesn't seem to get through the initWithBitmapDataPlanes function but gives no error. My question is: what am I doing wrong? Is this approach reasonable (if not, what would be better?).

  • how to create resources without VS C++ 2008 creating MFC files

    - by numerical25
    I am creating a WIN32 application and I want most of all my application events to be made through the message queue. But everytime I create a dialog box or any resource like that. The IDE auto generates code that I don't necessarily need. I believe it's MFC code not sure. here it is. // dlgChangeDevice.cpp : implementation file // #include "stdafx.h" #include "ZFXD3D.h" #include "dlgChangeDevice.h" // dlgChangeDevice dialog IMPLEMENT_DYNAMIC(dlgChangeDevice, CDialog) dlgChangeDevice::dlgChangeDevice(CWnd* pParent /*=NULL*/) : CDialog(dlgChangeDevice::IDD, pParent) { } dlgChangeDevice::~dlgChangeDevice() { } void dlgChangeDevice::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(dlgChangeDevice, CDialog) ON_CBN_SELCHANGE(IDC_COMBO5, &dlgChangeDevice::OnCbnSelchangeCombo5) END_MESSAGE_MAP() // dlgChangeDevice message handlers void dlgChangeDevice::OnCbnSelchangeCombo5() { // TODO: Add your control notification handler code here } Not sure what it is but I don't need it. I want to retrieve all my code through the dialog message queue. So what should I do ?? Just disregard it and delete it. Will a hurt anything by doing so ??

  • Entity Framework Create Database & Tables At Runtime

    - by dhsto
    I created some tables in an .edmx file and have been generating the database by selecting "Generate Database From Model" and manually executing an .edmx.sql file on the database to build the tables. Now, however, I am creating a setup dialog that allows the user to connect the program up to their own database. I thought running context.CreateDatabase would be good enough to create the database, along with the tables, but the tables are not created. What is the preferred method for creating the database and tables when the user specifies their own server and database to use, when originally starting with a model?

  • SQL CREATE TABLE Error

    - by Adam M-W
    Hi, I've been stuck on this one simple(ish) thing for the last 1/2 hour so I thought I might try to get a quick answer here. What exactly is incorrect about my SQL syntax, assuming I'm using mysql 5.1 CREATE TABLE 'users' ( 'id' MEDIUMINT(8) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, 'username' VARCHAR(20) NOT NULL, 'password' VARCHAR(40) NOT NULL, 'salt' VARCHAR(40) DEFAULT NULL, 'email' VARCHAR(80) NOT NULL, 'created_on' INT(11) UNSIGNED NOT NULL, 'last_login' INT(11) UNSIGNED DEFAULT NULL, 'active' TINYINT(1) UNSIGNED DEFAULT NULL, ) ENGINE InnoDB; Also, does anyone have any good tutorials about how to use Zend_Auth for complete noobs? Thanks.

  • Third party lib to create jar files?

    - by Synesso
    I've Goog'd but I can't find any third party library that will let you create a jar file programmatically. I amazed that even Apache commons-io doesn't seem to have such functionality. I'd rather not implement it myself as the API is rather low level. Are there any 3rd party libraries out there that will do the job? Edit: I meant programmatically in Java. I don't want to drop out to the shell and I don't want to work with java.io.*.

  • python open does not create file if it doesnt exist

    - by Toddeman
    I am using Python. What is the best way to open a file in rw if it exists, or if it does not, then create it and open it in rw? From what i read, file = open('myfile.dat', 'rw') should do this, no? it is not working for me (python 2.6.2) and im wondering if it is a version problem, or not supposed to work like that or what. The bottom line is, i just need a solution for the problem. I am curious about the other stuff, but all i need is a nice way to do the opening part. thanks in advance

  • Arguments against Create or Update

    - by Nix
    Recently someone stated that they thought all Creates should be CreateOrUpdates. Instinctively i thought bad, but now I am trying to find out if I have any grounds. Situation interface IService{ void Create(Object a); void Update(Object a); } or interface IService{ void CreateOrUpdate(Object a); } My first thought is if you implemented everything CreateOrUpdate then you have no control if someone accidentally sends you wrong data, or concurrency issues where someone changes a "primary" field right before you call update.... But if you remove those cases, are there any other cons?

  • How do I create "undo" in c++?

    - by b3y4z1d
    I've got a couple of codes to do some things but I need to create a function that undoes the previous task/addition/change.How do I do this in Borland C++? (the program stores strings of text in a text file using "list",it is stored and then erased unless I use the save-function I've created) right,so I don't know if I've forgotten to mention anything of importance for you to be able to help me better,but if there's something you're wondering about the functions just ask. I meant creating an undo function in a simple consol application by the way.

  • iPhone - Create not persistant entities in core data

    - by ncohen
    Hi everyone, I would like to use entity objects but not store them... I read that I could create them like this: myElement = (Element *)[NSEntityDescription insertNewObjectForEntityForName:@"Element" inManagedObjectContext:managedObjectContext]; And right after that remove them: [managedObjectContext deleteObject:myElement]; then I can use my elements: myElement.property1 = @"Hello"; This works pretty well even though I think this is probably not the most optimal way to do it... Then I try to use it in my UITableView... the problem is that the object get released after the initialization. My table becomes empty when I move it! Thanks

  • Hudson - Maven is failing (cannot create /dev/null/.m2) on Tomcat-6 - Gentoo

    - by John
    Hi there. I'm having major issues with getting Hudson up and running on a gentoo server with Tomcat 6. I'm able to deploy Hudson just fine, and I can browse the web-application, configure it and set up builds etc. However, when I try to run a build (in example "clean test" on a Maven2 project) I get this error ERROR: Failed to create /dev/null/.m2 I've google'd and for some it seems to be helping to put -DHUDSON_HOME=/home/hudson and -DMAVEN_HOME=/home/hudson in /etc/init.d/tomcat-6's JAVA_OPTS. However, I've tried that and by doing the same in /etc/conf.d/tomcat-6 , but I'm still getting this error. Has any of you had to deal with this before?

  • How to create an ARGB_8888 pixel value?

    - by vidstige
    Say I want to create an array of pixel values to pass into the createBitmap method described here. I have three int values r, g, b in the range 0 - 0xff. How do I transform those into a opaque pixel p? Does the alpha channel go in the high byte or the low byte? I googled up the documentation but it only states that: Each pixel is stored on 4 bytes. Each channel (RGB and alpha for translucency) is stored with 8 bits of precision (256 possible values.) This configuration is very flexible and offers the best quality. It should be used whenever possible. So, how to write this method? int createPixel(int r, int g, int b) { retrurn ? }

  • x86 linux - how to create custom malloc with address hint

    - by nandu
    Hi, I want to create a custom malloc which allocates memory blocks within a given address range. I am writing a pthreads application in which threads are bound to unique cores on a many-core machine. The memory controllers are statically mapped, so that certain range of addresses on main memory are electrically closer to a core. I want to minimize the latency of communication between cores and main memory by allocating thread memory on these "closer" regions. Any ideas would be most appreciated. Thank you! Nandu

  • Create a modifiable string literal in C++

    - by Anne
    Is it possible to create a modifiable string literal in C++? For example: char* foo[] = { "foo", "foo" }; char* afoo = foo[0]; afoo[2] = 'g'; // access violation This produces an access violation because the "foo"s are allocated in read only memory (.rdata section I believe). Is there any way to force the "foo"s into writable memory (.data section)? Even via a pragma would be acceptable! (Visual Studio compiler) I know I can do strdup and a number of other things to get around the problem, but I want to know specifically if I can do as I have asked. :)

  • XUL: create menu items dynamically and set "selected" attr

    - by Michael
    I have a firefox extension Options pref panel, where I should dynamically create menu items and select particular item to be current. here is the XUL file part <menulist id="rss_service_combo"> <menupopup id="rss_service_menu"/> </menulist> Then in load event of the pref panel, using js I append menuitem elements into menupop. This is working fine. The only problem is that even if I set the selected element the item is not selected and combo box is initially empty. The only way is working at the moment is if I manually add those menuitems into XUL file and set selected attribute, but I need to do it dynamically.

  • Python - Create a list with initial capacity

    - by Claudiu
    Code like this often happens: l = [] while foo: #baz l.append(bar) #qux This is really slow if you're about to append thousands of elements to your list, as the list will have to constantly be re-initialized to grow. (I understand that lists aren't just wrappers around some array-type-thing, but something more complicated. I think this still applies, though; let me know if not). In Java, you can create an ArrayList with an initial capacity. If you have some idea how big your list will be, this will be a lot more efficient. I understand that code like this can often be re-factored into a list comprehension. If the for/while loop is very complicated, though, this is unfeasible. Is there any equivalent for us python programmers?

  • Create link to Sitecore Item

    - by Zooking
    I know I have done this before but I can't seem to remember where or how. I want to create a link to an Item in Sitecore. This code: Sitecore.Data.Items.Item itm = Sitecore.Context.Database.GetItem(someID); return itm.Paths.Path.ToString(); Produces the following string: http://localhost/sitecore/content/Home/Item1/Item11/thisItem I would like to have this string instead: http://localhost/Item1/Item11/thisItem.aspx What is the correct way to get the path to the item? In this case I can't use a normal Sitecore link: Sitecore.Web.UI.WebControls.Link

    Hey all, I posted a similar topic for RoR, but didn't know how to edit my tags, so I'm making a new one for C#... I'm looking for a HTML editor which can be integrated in a C# app that has the possibility to create forms. Not forms per se, but I need the possibility to add radiobuttons, input fields, checkboxes and so on. There are many editors that provide Richt text (bold, italic, indentation and so on) but what I need goes a bit further, so help is appreciated. Thanks!

  • Why does my code fail to create a directory in "C:\Program Files" under Windows 7?

    - by sunil.nishad87
    I am using Windows 7 and I have to run one program in that windows but that program working in Windows XP. This is a Visual C++ program and I am using Visual Studio 2008 for this. When I am running my application, it does not throw any errors, but it does not create a directory in "c:\program files\". So can anyone help me to create directory and exe file?
