• Can I grant explicit Javascript methods to a different-host iframe?

  - by Matchu

  I'm thinking about a system in which I allow users to create Javascript-empowered widgets for other users to embed in their dashboard on my website. I'd like to limit these widgets fairly strictly, so each would exist as an iframe kept on its own unique hostname: the widget with ID #47 would be accessible at w47.widgets.example.com, for example. It would be helpful, for permission-granting dialogs and the like, to allow the widget to call very specific methods explicitly granted by the parent window, without authorizing the iframe to do whatever it likes with the parent frame on the user's behalf. Is it possible for a parent document to explicitly allow certain method calls to a child document on a different host?

• java detect clicked buttons

  - by user253530

  I have multiple panels on a JFrame window. I am going to populate each panel differently every time. For example: i start the GUI: (image center panel, right panel, bottom panel). Center panel is populated with 20 buttons, right panel with 10 buttons and bottom panel with 3. second start of the GUI (same gui). Center panel has 50 buttons, right panel has 12 buttons, bottom has 3. So everytime there is a random number of buttons, impossible to be all uniquely named. Given the fact that I don't have a unique name for each button (just a list) I would like to know which buttons were clicked according to the panel they belong to. is that possible?

• How can I set the buffer size for the underneath Socket UDP? C#

  - by Jack

  Hi all As we know for UDP receive, we use Socket.ReceiveFrom or UdpClient.receive Socket.ReceiveFrom accept a byte array from you to put the udp data in. UdpClient.receive returns directly a byte array where the data is My question is that How to set the buffer size inside Socket. I think the OS maintains its own buffer for receive UDP data, right? for e.g., if a udp packet is sent to my machine, the OS will put it to a buffer and wait us to Socket.ReceiveFrom or UdpClient.receive, right? How can I change the size of that internal buffer? I have tried Socket.ReceiveBuffSize, it has no effect at all for UDP, and it clearly said that it is for TCP window. Also I have done a lot of experiments which proves Socket.ReceiveBufferSize is NOT for UDP. Can anyone share some insights for UDP internal buffer??? Thanks

• starting .net application from command prompt is having issue when path is in SHORTNAME

  - by ioWint

  when we start our .net application using a double click on the explorer or from command prompt where your folder path is proper full name then there is no issue at all. But when you start it from command prompt with the path being a Shortname involving a ~ the application behaves weird. IF is entering condition though the condition evaluates to FALSE in quick watch. Accessing a value of a variable in quick watch and immediate window shows value. but when you use it to assign to another variable in code, it returns NULL / no value. another observation: when you attach Visual studio to debug the app, and when you go about "Set as next statement" visual studio is giving options to select which dll to work up on. i have never seen this prompt before!

• indicate tuncation in ToolTipStatusLabel automatically

  - by harper

  I have a .NET application with a StatusStrip holding three ToolTipStatusLabels. The Text of the labels are filled from the application as they show the status. For some circumstances they can hold an empty text. When I resize the window, the ToolTipStatusLabels are hidden when they cannot be fit in the StatusStrip. I would like to have the text truncated when the label cannot be fit in the StatusStrip. The default behavior to hide the label makes it difficult to distinguish between empty text or hidden label. To indicate that the text is truncated automatically, this should be indicated with an ellipsis (...). How can this be done?

  - by ozan

  I have a page (A) including a BUTTON with a function close_window() , however when I embed A to my main page (B) using iframe, the close_window() can't work as expected since there is no more window anymore, and I am not able to remove the button from the iframe since A is on another domain (Security issues prevents).

And the only way I think is to put a white image just to the place where that button exists on my iframe, externally. is Smthing like that possible? I want the image to be on the top of iframe? Or do you have any other idea ? Thanks for helps.

• Rails + facebox + authlogic - how?

  - by Vitaly

  Hello, on my web site I want to have login/registration form in modal window done using facebox (jQuery plugin). What is better: Create view with one method and template that has form and refer facebox to this view. Create static HTML file in public directory and refer facebox to this static page. What I want to achieve is: Easy verification (like "user name already taken", "password confirmation doesn't match password" and stuff like that). Easy submit and redirect I'm new to Rails, I just know about forms verification in Django, so for Django I would probably choose option 1, but it might be another thing in Ruby.

• Pass information back from an iframe?

  - by ThinkBohemian

  Right now i'm building a firefox plugin that duplicates some functionality on my website. It takes in an email address and then returns information to the user. The easiest way to do this in the plugin is to use an Iframe and render that super simple form on my website. All of this works great, but to make the plugin really useful, i would like the plugin to have access to the information that the iframe renders, so it can use it in the current window that the user is in. Is it possible to pass information back through an Iframe in this manner? I know there are quite a few domain access restrictions with Iframes, so any help or insight is appreciated!!

• c++ networking issue- retrnsmittion without ccongestion

  - by gln

  I wrote an application in c++ which send data over tcp connection to several machines.as part of the protocol I use in my application, the other side sends hearbeat messages from time to time, then I know that the connection is still alive. now, I want this application to work on 100 machines or more at the same time. but, I see that sometimes I don't get these heartbeat messages although they sent: I see in wireshark that the packet arrived, then my OS doesn't ack on this message, so there are some retransmit without any ack from my OS. if I look in the window size property - I saw that there is no issue in this part. what can be the root cause for this behavior? it is something in my code that I should change? this is my select code: int res = select(fdCount, &readFds, NULL, NULL, NULL ); I'm using server 2008 r2. Please help me! thanks

• How to create a cross-plataform application, doing the interface modules (Mac/Qt/GTK+) in a totally

  - by Somebody still uses you MS-DOS

  I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? Is it possible to create that mac interface in another OS using an IDE? How did the developers create this software with so many interfaces, in a independent way?

• Python win32api not moving mouse cursor in VirtualBox

  - by wes

  I'm trying to use this Python code: import math for i in xrange(500): x = 500 + math.sin(math.pi * i / 100) * 500 y = 500 + math.cos(i) * 100 x, y = int(x), int(y) win32api.SetCursorPos((x, y)) time.sleep(.01) taken from here to move the mouse cursor in an XP VirtualBox. The mouse icon will flicker to the appropriate graphic (when it hits the edge of a window it turns into the <- resize image, for instance), but it doesn't actually move the visible cursor. I can move the mouse around while the code is running. Same result using the ctypes example in the above link. It works fine in the Win7 host. I have Guest Additions installed, if that matters.

• CoreData and many NSArrayController

  - by unixo

  In my CoreData Application, I've an outline view on left of main window, acting as source list (like iTunes); on the right I display a proper view, based on outline selection. Each view has its components, such as table view, connected to array controller, owned by the specific view. Very often different views display same data, for example, a table view of the same entity. From a performance point of view, is better to have a single array controller per entity and share it between all views or does CoreData cache avoid memory waste?

• Process.WaitForExit not triggering with __debugbreak

  - by Cypher2100

  I'm trying to write a program to test student code against a good implementation. I have a C++ console app that will run one test at a time determined by the command line args and a C# .net forms app that calls the c++ app once for each test. The goal is to be able to detect not just pass/fail for each test, but also "infinite" (5secs) loop and exceptions (their code dying for whatever reason). The problem is that not all errors kill the C++ app. If they corrupt the heap the system calls __debugbreak which pops up a window saying Debug Error! HEAP CORRUPTION DETECTED... My C# app is using Process.WaitForExit(5000) to wait, but this error doesn't count as an exit, so I see a timeout. So my question is, how can I either get the C# app to detect that this is an error OR how can I get the C++ app to die when this error occurs rather than giving a dialog box and asking if I want to debug?

• Flash: Correctly handling click-and-drag outside the browser?

  - by David Wolever

  What's the correct way to detect, from Flash, when someone has started a drag within the browser (eg, a MOUSE_DOWN event), dragged the mouse outside the browser window, released the button, then moved the mouse back over the browser? For example (assuming StackOverflow was a Flash application): I've tried the "obvious" thing, checking event.buttonDown in the MOUSE_MOVE handler, but even though the mouse button is up, event.buttonDown is true in step 2 (above). So, is there any other way to check the "real" status of the mouse button? Or any other way to handle this situation?

• OpenGL and layouts

  - by Hnefi

  I'm using OpenGL to render a game view in my android application. The game is turn based and I wish to add some buttons to the interface. I'd prefer to use standard Android widgets, structured in an XML-generated layout (or, if I have to, a hardcoded layout) and put the OpenGL view in its own window as part of that layout. So in regards to this, I have 3 questions: 1: Is such a thing possible? I've done a few half-hearted tries, but have had no luck so far. 2: Is such a thing advisable? Does it carry a significant performance penalty, for example, over using OpenGL-based homebrew widgetry? 3: Is it possible to pass particular arguments to instances created in XML layouts? For example, my current OpenGL view has three arguments in its constructor; is it somehow possible for me to invoke that particular constructor with particular parameters when it's part of a layout?

• How to stop C# compile on first error in VS 2010 (VS 2008 macros don't work)!

  - by Ben Robbins

  At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to automatically stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window? I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). I'd also note that in VS 2008 we used macros similar to some of the answers below but they don't work in VS 2010 (at least I couldn't get them to as the environment events don't seem to fire in VS 2010).
