• Adobe Illustrator - File Grouping

  - by Gern Blandston

  Is there a way to open multiple AI files (say 3 individual files) and somehow save in a way that I can open the same 3 files simultaneously in the future? I always want the multiple files to open together. Situation: We design products with AI. A single product may have multiple versions. The designer typically creates 1 AI file, then puts all versions of the product in the single file. I need them to put each version in a separate file for an integration project, but this creates more work for them. The solution I'm looking for would allow them to open all the relevant AI file and somehow same them all as a group. Next time, they open the group and all AI files open together. Thank you

• Store database, good pattern for simultaneous access

  - by dygi

  I am kinda new to database designing so i ask for some advices or some kind of a good pattern. The situation is that, there is one database, few tables and many users. How should i design the database, or / and which types of queries should i use, to make it work, if users can interact with the database simultaneously? I mean, they have access to and can change the same set of data. I was thinking about transactions, but I am not sure, if that is the right / good / the only solution. I will appreciate some google keywords too.

• Component properties working at designt time but not runtime - ???

  - by delphi-rulez-2010

  I am creating a component that uses a collection and collection items of panels. I can't seem to get the colors to work at runtime, but yet they seem to work just fine at design time. You can download the component source code here: http://www.shaneholmes.net/pasfiles/ There is a Consoles (Tcollection) property, status colors property, and a Edit mode property Each console (TCollectionItem) has a status property when changed, the consoles property is changed based on the components StatusColors property. When the components EditMode property is set to true, you can move the panels around at runtime. Question: Why does the colors only work at designtime and not runtime. thanks

• Why are there two implementations of std::sort (with and without a comparator) rather than one implementation with a default template parameter?

  - by PolyVox

  In my code I'm adopting a design strategy which is similar to some standard library algorithms in that the exact behavior can be customized by a function object. The simplest example is std::sort, where a function object can control how the comparison is made between objects. I notice that the Visual C++ provides two implementations of std::sort, which naturally involves code duplication. I would have imagined that it was instead possible to have only one implementation, and provide a default comparator (using operator< ) as a default template parameter. What is the rational behind two separate versions? Would my suggestion make the interface more complex in some way? Or result in confusing error messages when the object does not provide operator Thanks, David

• Scraping html WITHOUT uniquie identifiers using python

  - by Nicholas Law

  I would like to design an algorithm using python that scrapes thousands of pages like this one and this one, gathers all the data and inserts it into a MySQL database. The script will be run on a weekly or bi-weekly basis to update the database of any new information added to each individual page. Ideally I would like a scraper that is easy to work with for table structured data but also data that does not have unique identifiers (ie. id and classes attributes). Which scraper add-on should I use? BeautifulSoup, Scrapy or Mechanize? Are there any particular tutorials/books I should be looking at for this desired result? In the long-run I will be implementing a mobile app that works with all this data through querying the database.

How i solve the memory leak problem in UIImage *_renderImage?

• Organizing PHP includes in your development environment

  - by Andrew Heath

  I'm auditing my site design based on the excellent Essential PHP Security by Chris Shiflett. One of the recommendations I'd like to adopt is moving all possible files out of webroot, this includes includes. Doing so on my shared host is simple enough, but I'm wondering how people handle this on their development testbeds? Currently I've got an XAMPP installation configured so that localhost/mysite/ matches up with D:\mysite\ in which includes are stored at D:\mysite\includes\ In order to keep include paths accurate, I'm guess I need to replicate the server's path on my local disk? Something like D:\mysite\public_html\ Is there a better way?

• How to handle recursive parent/child problems like this?

  - by lsdude

  In web dev I come across these problems a lot. For example, we have a giant list of URLs that are in this format: /businesses /businesses/food /businesses/food/wendys /businesses/food/wendys/chili /businesses/food/wendys/fries /businesses/food/wendys/chicken-nuggets /businesses/pharmacy/cvs /businesses/pharmacy/cvs/toothpaste /businesses/pharmacy/cvs/toothpaste/brand ... and then we need to output each one, where the parent category is in h1 tags, the child is in h2 tags, and the children of that are in h3 tags. I can handle this but I feel my code is messy. I'm sure there is a design pattern I can use? Langs are ruby/php usually. how would you handle this?

• cross domain DOM access and manipulation in Java ?

  - by gaqer

  In my Java app, how can I incorporate the browser (which loads and renders URLs) in Swing and access it's DOM and manipulate HTML ? How can you embed such browser in a Rich Internet Application and access it's DOM ? More specifically, Vaadin ? Is there a HTTP proxy class that can load an external URL, and render it to the user ? This was what I was doing on LAMP stack....but I want to switch to Vaadin or some Java web framework where I can just use Java to do everything from server-side to client-side logic design, so I can focus more on application logic. (aka looking for developer friendly frameworks like Vaadin). Thank you and have a great weekend !

• I have a problem implementing states in my Flex app, please help!

  - by ben

  Hey guys, I'm trying to work out how to use states in my Flex app. I've created two states, State1 and Stage 2. Both are based off the base state. I've created a few visual elements for State1, and given each of them includeIn="State1". But when I'm in design mode and click on State2, these elements are still visible? Why is that? If I try to delete them while State2 is selected, all that happens is RemoveChild is added to the State2 tag. Is this how I'm supposed to do it? Thanks for reading!

• height: auto does not work to automatically resize header

  - by slevin

  I'm trying to do a simple thing in CSS I have a header tag and inside that a couple of h tags. So, in order to have a responsive design I do height:auto; inside the header tag, so it will automatically stretch to contain the h tags. Right? But does not work, headeris just a line in the top of the page. t should stretch to contain the titles, right? What am I missing? Is it a good practice to put CSS in the h tags and not style header at all? So h tags will be like the header in user's eye? Thanks in advence Check it here

• Can anyone explain why this behaviour might be happening in Windows Forms?

  - by gizgok

  I'm developing a Windows Forms Application. See attached image for the Interface. Now I've put a close button (X) in the Panel(say Panel2) which has Application Constants as label.The first combo box is in another panel(say Panel1). Now when I click on the X button in Panel 2 I want the Panel to be invisible and the combo box text to be blank. Simple enough. So I write Panel2.visible=false; comboBox1.SelectedIndex=-1; When I click on X, the text in combo box goes blank, then I have to click again for the Panel2 to go invisible. Then I changed the sequence comboBox1.SelectedIndex=-1; Panel2.visible=fasle; and this works smooth. Not sure why this might be happening? Is there anything that I might be doing with my form design/code to have such a behaviour?

• No recent books on MPI: is it dying?

  - by Jono

  I've never used Message Passing Interface (MPI), but I've heard its name thrown about, most recently with Windows HPC Server. I had a quick look on amazon to see if there were any books on it, but they're all dated around 7 or more years ago. Is MPI still a valid technology choice for new applications, or has it been largely superceded by other distributed programming alternatives (e.g. DataSynapse GridServer)? As it's not really an implementation, but rather a standard, what is the likelihood (assuming it's not dead) that learning it will result in better design of distributed programming systems? Is there something else I should be looking at instead?

• What are the advantages and disadvantages of plug-in based architecture?

  - by RP

  I want to do the architectural design for a software that can be used integrate various third party software’s (executable) under one platform. Standard project types will be added to the platform by default. The project type defines the way in which the different software will be executed and their input and output files. The user can customize the available standard project type and that will be added to the platform as new project type which defines new custom execution flow. Also it should support easy extension and customization of the features. I read that plug-in based architecture supports both. What are the advantages and disadvantages of plug-in based architecture? Do we have any better architecture which can be used for this kind of scenario? Thanks in advance:)

• How to set UITableView to Grouped?

  - by 4thSpace

  In an iPhone navigation based app, I want to add a second tableview but have its design available in IB. I've added a new empty XIB and dragged a UITableView onto it. I want to setup the layout through IB. I've created a controller for this tableview and set the File's Owner class in IB to this controller. I linked the tableview to File's Owner as well. I set the tableview to grouped in IB. However, that does not translate at runtime. I still have a plain tableview. In fact, none of the Inspector settings work at runtime. What have I missed?

• Saving data in a inherited django model

  - by aldeano

  I'm building an app to save data and some calculations made with those datas, the idea is keep the data in one model and the calculations in other. So, the models are like this: class FreshData(models.Model): name = models.CharField(max_length=20) one = models.IntegerField() two = models.IntegerField() def save(self, *args, **kwargs): Calculations() Calculations.three = self.one + self.two super(FreshData, self).save(*args, **kwargs) Calculations.save() class Calculations(FreshData): three = models.IntegerField() I've got a valueerror pointing out "self.one" and "self.two" as without value. I keep the idea in witch my design is wrong and django has a simpler way to store related data.

• text watermark on website? how to do it?

  - by Tim

  I am a C++/C# developer and never spent time working on web pages. I would like to put text (randomly and diagonally perhaps) in large letters across the background of some pages. I want to be able to read the foreground text and also be able to read the "watermark". I understand that is probably more of a function of color selection. I have been unsuccessful in my attempts to do what I want. I would imagine this to be very simple for someone with the web design tools or html knowledge. Any links or sample code? Thanks

• Get other classes from an element with Jquery

  - by Jigs

  I am working on a small bit of script that will allow for easy and flexible creation of buttons. My buttons are made of three parts, a left, a right and a streched middle piece. There are three different sizes and three different colours of each. I have written the code that resizes the button to fit the text. Now I am looking to add the ability to easily set the colour and size. I was thinking of using three classes something like <div class="button blue big"> My script already loops through the button classes using each. Now I need to find out what other classes are set and adjust the pictures and dimentions used to fit. So how can I find out what other class selectors an element has? Also I am fairly new to jquery/javascript so I am wondering if storing the design as class selectors is the best way.

• How to bind data in silverlight? In case I don't know which columns would be retrieved from database

  - by kwon

  I am trying to bind data from database to datagrid in silverlight. When I get typed data from DB, it is no problem since I use List<'EntityObject' collection object for example. However, sometimes I need data which I won't be able to know how many and what columns will be generated in design time. In this case, I cannot use typed collection like List<'EntityObject'. In addition, it is not able to use DataSet in silverlight. So, in this case and situation, how to solve this kind of problem? Thanks in advance Kwon

• 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.

• Questions about "casting operation" in OOP

  - by rhapsodyn

  When programming, we usually use some type-casting operations. When the casting happens on the objects "on the same level", it feels ok. But when it happens on the ojects "on the different levels"(mainly between father and son), it feels weird. Considering this: Class Son extends Father WhenSon s = (Son)father;, it's absolutely unreasonable. Because a "Son" is not a "Father" anymore, "Son" may grow up with some new properties "Father" doesn't have, the casting operation makes these properties unknown. On the other hand, Father f = (Father)son seems reasonable, but according to LSP "An instance of a derived should be able to replace any instance of its superclass" A "Son" can do anything his "Father" can, so the casting operation seems useless. So can i say that these casting operations are agaisnt OO design principle but necessary?

• What's the difference between Path and Polygon control? + issues when designing custom drawing user

  - by tomo

  I'm starting to design a custom control with rather complex drawing. It will be a kind of chart (a kind of radar chart). It will be composed of a few axises with labels, line-regions (like spider-network) and filled shapes. The main question is what's the difference between using Path control and Polygon control? What's better to use here? The goal is to prepare control with minimal amount of c# and try to do as much as possible in xaml / binding. The next important requirement is that control should resize to parent containers' width - if possible without any long recalulations in c#.

• When accessing ResultSets in JDBC, is there an elegant way to distinguish between nulls and actual z

  - by Uri

  When using JDBC and accessing primitive types via a result set, is there a more elegant way to deal with the null/0 than the following: int myInt = rs.getInt(columnNumber) if(rs.wasNull())? { // Treat as null } else { // Treat as 0 } I personally cringe whenever I see this sort of code. I fail to see why ResultSet was not defined to return the boxed integer types (except, perhaps, performance) or at least provide both. Bonus points if anyone can convince me that the current API design is great :) My solution was to write a wrapper that returns an Integer (I care more about elegance of client code than performance), but I'm wondering if I'm missing a better way to do this.
