• Adobe After Efects Plugin With Cocoa (Overriding malloc)

  - by mustISignUp

  Messing about a bit, i have a working Adobe After Effects plugin with a bit of Obj-c / Cocoa in it (NSArray and custom objects - not ui stuff). The SDK guide states:- Always use After Effects memory allocation functions. In low-memory conditions (such as during RAM preview), it’s very important that plug-ins not compete with After Effects for OS memory, and deal gracefully with out-of-memory conditions. Failing to use our functions can cause lock-ups, crashes, and tech support calls. Don’t do that. If you’re wrapping existing C++ code, overloading new and delete to use our functions will save substantial reimplementation. On Windows, derive all classes from a common base class which implements new and delete. so my question.. is something compatible with the above statement possible in Obj-c?

• Imbedded wpf textbox does not accept input

  - by pro3carp3

  I put a wpf textbox inside a combobox to allow the user to enter a custom setting. I can read the keypress in the keydown event, but the text in the textbox does not change. What am I missing? <ComboBoxItem Name="GridSizeCustom"> <StackPanel Height="30" Orientation="Horizontal"> <TextBlock Text="Grid Size (8 - 200)" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0" /> <TextBox Name="GridSizeBox" KeyDown="test" Width="50" /> </StackPanel> </ComboBoxItem> I step through this event handler when I press a key, but no change to the textbox text: public void test(Object sender, KeyboardEventArgs e) { int x = 0; } Any help is appreciated. Thanks.

• Domain entities into (ASP.NET) Session, or better some kind of DTOs?

  - by Robert

  Currently we put Domain Objects into our ASP.NET Sessions. Now we considering moving from InProc sessions to state server. This requires that all objects inside session are serializable. Instead to annotate all objects with the [Serializable] attribute, we thought about creating custom-session objects (DTO Session Objects?), which only contain the information we need: CONS: Entities must be reloaded, which requires additional DB round-trips PROS: Session State is smaller Session information is more specific (could be a CON) No unneeded annotation of Domain-Entities What do you think? Should we use some kind of DTOs to store inside the session, or should we stick with god old entities?

• Infinite loop when Selecting a panel?

  - by serhio

  I have a winform in witch I have a custom LongPanel with textboxes.

I receive infinite panel Leave events(sender is a panel)... any idea why? EDIT: precision on panels parents: Form => SplitPanel => _AttachedPanel | _LongPanel (_LongPanel contains a reference to _AttachedPanel)

• Is this a secure way to structure a mysql_query in PHP

  - by Supernovah

  I have tried and tried to achieve an SQL injection by making custom queries to the server outside of firefox. Inside the php, all variables are passed into the query in a string like this. Note, by this stage, $_POST has not been touched. mysql_query('INSERT INTO users (password, username) VALUES(' . sha1($_POST['password']) . ',' . $_POST['username'] . ')); Is that a secure way to make a change?

• C# new class with only single property : derive from base or encapsulate into new ?

  - by Gobol

  I've tried to be descriptive :) It's rather programming-style problem than coding problem in itself. Let's suppose we have : A: public class MyDict { public Dictionary<int,string> dict; // do custom-serialization of "dict" public void SaveToFile(...); // customized deserialization of "dict" public void LoadFromFile(...); } B: public class MyDict : Dictionary<int,string> { } Which option would be better in the matter of programming style ? class B: is to be de/serialized externally. Main problem is : is it better to create new class (which would have only one property - like opt A:) or to create a new class derived - like opt B: ? I don't want any other data processing than adding/removing and de/serializing to stream. Thanks in advance!

• calling javascript function inside orkut iframe

  - by tsetsik

  Hi guys, I'm having a web game loaded in orkut application via iframe so there are the orkut iframe and mine iframe inside the xml. Everything is ok, but now I need to have a button for inviting some friends and wall posts from some features. I didn't find a way for including the orkut javascript in the game's code so the first thing that pops into my mind was to call a custom function in the xml by using: window.parent.myFunction(); but it gives me error: permission denied. I've tried some other ways of reaching that function but the error is the same. Does anybody know a way of doing that or this can't be done ?

• Databinding a list (in an object) to a combobox in VB.net

  - by Casey

  VB 2008 .NET 3.5 I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment. My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc. I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment." In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use. I have tried a few ideas, but none of them work properly. Any ideas on how to do this?

• Distributing cpu-bound compression jobs to multiple computers?

  - by barnaby

  The other day I needed to archive a lot of data on our network and I was frustrated I had no immediate way to harness the power of multiple machines to speed-up the process. I understand that creating a distributed job management system is a leap from a command-line archiving tool. I'm now wondering what the simplest solution to this type of distributed performance scenario could be. Would a custom tool always be a requirement or are there ways to use standard utilities and somehow distribute their load transparently at a higher level? Thanks for any suggestions.

• Singleton wrapper for Context

  - by kpdvx

  I'm considering creating a singleton wrapper for a Context so my model objects, if necessary, can open and read from a database connection. My model objects do not have access to a Context, and I'd like to avoid needing to pass a reference to a Context from object to object. I was planning to place into this singleton a reference to the Context returned by Application.getApplicationContext(). This singleton object would be initialized in my custom Application instance before anything else would need to or have a chance to use it. Can anyone think of a reason to not do this?

• ASP.Net databinding in tag

  - by Psytronic

  I know you can bind in the code-behind, but I don't quite understand how it works if you want to declare it within the controls tag. This is for a custom collection. I thought it was just Datasource="<%# MyCollection %" Where MyCollection is an exposed property of the class in the code behind? MyCollection{ get{ return _MyCollection;}} Something like that. But it doesn't seem to work that way, so can I not bind this way, or am I missing something?

• How can i get the selected option name or id of a select element using jQuery

  - by bill

  Hi All, i have a "questionairre" that is made up of a series of select boxes. i need to use two properties in the options. For each selected option i need the value (which i know how to get and is working fine) but i also need to store an additional value which represents the id of the specific option in a DB. One solution would be to put the two values in the "value" property and parse it out.. but if there is some other property i can use that might be easier and clearer.. can i add a custom property?? like databaseId that could be accessed with jQuery? thanks for ANY suggestions.

• Intent resolution in Android

  - by Saksham

  Hello community, If I want to create custom address book (which overrides my phone's default address book), and if I want it to be used by all applications, what should be my intent filter? Does Android allow me to do such a thing considering the fact that such a third-party app could potentially be malicious?! And, if I want to have yet another address book application, I suppose the second app also has same intent-filter, isn't it? How does the framework decide which app to pick if I click on Contacts button when making a call? In other words, how does the framework resolve intents in case there is a conflict between multiple intent-filters? I'm new to android, so please excuse me if this question is stupid. I would like to get some feedback in any case! Thanks in advance, Saksham

• Capturing clicks even when stopPropagation has been called (ie by 3rd party code)?

  - by josh

  I want to detect any click that happens on a page (to close a custom context menu). I'm using jQuery and trying to do $(document).click(function(){ ...close my context menu ... }); However, I'm using some code that calls evt.stopPropagation() in the click handlers for certain elements on the page, and those clicks aren't making it up to my top-level handler. Is there any way of capturing those clicks? Can be jQuery or not jQuery, as long as it works cross-browser.

• JSF 2 Content Controller (pull in content based on URI)

  - by gerges

  Hey All, I'm new to JSF and am trying to make a content controller. Basically whenever someone makes a request to www.myapp.com/external/** I'd like to forward to a controller that pulls external content into a page template and spits it out to the user. I was able to achive this pretty easily in Spring 3, but I'm a little confused on where to start with JSF. I feel like I'd need to create a custom servlet to handle /external/**? But what would the class of this servlet be? What would it consist of? Any help is appreciated!

• Customized annotation problem

  - by user128647

  I want my custom UIView (.Xib View) to appear when user tabs on pins (not apple's callOutBubble) and in that UIView there should be a button which fires an IBAction on touched down event. Therefore I have added an AddObserver method to MKAnnotationView. which responds to touch events over pin in MKMapView. I have also added 3 buttons over that XIB view, which have also assigned IBActions. But when I run my application, buttons in the customized annotation view are not responding to IBAction (Touch Down). Why does this happen, and how can I fix it? I need to call a method when those 3 buttons are tabbed.

• Can an Oracle user get a list of its own running sessions without access to v$session?

  - by Nick Pierpoint

  I have an application that runs a process and I only want one process to run at a time. Some options are: Use an object lock to prevent subsequent processes running. This would be fine, but I want the calling session to return immediately and not wait for the running session to complete. Use a custom Y/N to set whether a process is running or not. I set a "Y" flag at the start of the process and set it to "N" when it finishes or fails. Also fine but feels like I'm re-inventing the wheel and doesn't feel like the way to go. It also falls short if the running session is killed as the flag stays at "Y". Use dbms_application_info.set_module This approach seems the most robust, but if I'm to know there's an existing running process I think I need to be able to query v$session and I don't want this application to have such wide access. Any ideas?

• UITextField in UITableViewCell Help

  - by W Dyson

  Hello All, I have scoured the internet looking for a good tutorial or posting about having a UITableView populated with a UITextField in each cell for data entry. I want to keep track of each UITextField and the text written within it while scrolling. The tableView will be sectioned. I have been using a custom UITableViewCell but I'm open to any method. Also, is it possible to use the textFields as ivars? If any of you could point me in the right direction, it would be greatly appreciated. Thank you in advance!

• Given a user control with a form containing validation can I validate entirely server side?

  - by JoshBaltzell

  We have an existing User Control that was built to dynamically generate a web form for an end user. This form includes required field validators, custom validators that use server side code and Regular Expression validatiors. We now have a need to use all these validators to verify that all the needed data is entered when using a separate ordering process that cannot be validated in the same way, but has the same validation requirements before it is added to the database. I would like to use this user control to validate the input by passing it all the values and checking the validation summary. The only way I know how to do this is to render it to a page on the client side and trigger the form submit. Is there any way to populate and validate a web form entirely on the server side?

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??

• How to arrange labels in a flowlayout manner?

  - by Tim Büthe

  How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

• Broadcast message or file to nearby Bluetooth devices

  - by Medjeti

  Hiya, A client of ours is attending a business fair and would like to push some sort of "welcome message" to people visiting their space. I'm not too familiar with Bluetooth, so I have a few questions: What kind of content can you transfer via Bluetooth? (Is it files only or is it possible to send a simple text message?) Is it possible to push content only to recipients within a certain distance? (ie. based on signal strength or similar) Can anybody recommend a piece of software that can do some or all of the above? If necessary we could program a custom solution ourselves (.NET), but I'm sure there must be a program out there that can do the job. I've googled a bit and came across the 32feet.NET framework - does anybody have any experience with this framework? Thanks in advance for any suggestions!

• mysql_close(): supplied argument is not a valid MySQL-Link resource

  - by maxedison

  I'm trying to get the hang of using custom session handlers to store session data in a MySQL database. However, I keep getting the following warning: mysql_close(): supplied argument is not a valid MySQL-Link resource Here's the code I'm using, which I got from here: function _open(){ global $_sess_db; $_sess_db = mysql_connect("localhost", "root", "******"); if ($_sess_db) { return mysql_select_db('style', $_sess_db); } return false; } function _close(){ global $_sess_db; return mysql_close($_sess_db); //error happens here } The full text of the error message ultimately points to the final "return mysql_close($_sess_db);" line. I can confirm that the mysql_connect info does in fact work, and I do have the rest of the session handler functions defined as well. And in case it helps, I get these errors immediately upon page load, without actually calling any of the session handler functions, and without having any current sessions open.
