• PRINTER SET UP IN EXCEL VISUAL BASIC

  - by Gina

  I am trying to assign a cell in excel for the user to type the printer name where they want the print out to go and then use that value in the Application.ActivePrinter = (use the cell value) Even though I have done the programming assigning a name to the cell and using it in a variable it is giving me an error. I have set my variable as string, text, object and variant already and it's not working. Do you know what code should I use to be able to do this?

• Understanding Scope on Scala's For Loops (For Comprehension)

  - by T. Stone

  In Chapter 3 of Programming Scala, the author gives two examples of for loops / for comprehensions, but switches between using ()'s and {}'s. Why is this the case, as these inherently look like they're doing the same thing? Is there a reason breed <- dogBreeds is on the 2nd line in example #2? // #1 ()'s for (breed <- dogBreeds if breed.contains("Terrier"); if !breed.startsWith("Yorkshire") ) println(breed) // #2 {}'s for { breed <- dogBreeds upcasedBreed = breed.toUpperCase() } println(upcasedBreed)

• Switching to Java from C++: What are the key points?

  - by Roddy

  I'm an experienced developer, but most of my OO programming experience has been with C++ (and a little Delphi). I'm considering doing some Android work, hence Java. Coming from the C++ background, what areas of Java are most likely to surprise/annoy/delight me? I felt sure this would already have been asked, but my searches haven't turned up a similar question. CW, of course.

• What's the right Java generic for a collection of elements with unique addressable indices?

  - by Rocreex

  I'm on my way to programming a database application and in our course we are told to implement a library of elements using one of the Java Collections. Each of the elements has a unique ID with which it's supposed to be addressed. Now I am wondering how this can be done. I though about using a ListArray but this won't work because the only way of addressing List elements is through the index which you can't control. Do you have some advice for me?

• Security concerns for a multi-lingual web application.

  - by The Rook

  I am converting a PHP MySQL web application written for English language into a Multi-Language site. Do you know any vulnerabilities that affect web applications in another language? Or perhaps vulnerabilities that could be introduced in the conversion of code base to support multiple languages. (If you know any vulnerabilities of this type in another programming language I'll give you a +1)

• Which IDE / code editor was the first to introduce a code completion feature?

  - by Uri

  I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

• How can you distribute the color intensity of two images using its gradients?

  - by Jeppy-man

  Hello everyone... I am working on an automatic image stitching algorithm using MATLAB. So far, I have downloaded a source code much like the one that I had in mind and so, I'm currently studying how the code work. The problem is, when stitching two or more images together, their color intensity will most probably be different from each other so the stitched seams will be visible to the eye... So, right now, I'm trying to find out how to redistribute their color intensity using the images gradients so that the whole stitched image will have the same color intensity. I hope someone can help me out there and if so, thank you very much...

• android drawable changes sizes on screen when reading image from file

  - by Daniel Benedykt

  Hi I have an image on a private file. I read the file, create the drawable, and assign it to an ImageView. The ImageView has WRAP_CONTENT so the size is automatic. On 320x480 screens, the image looks good But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100. Of course it has something to do with the density but not sure how should I resolve this. This is my code: FileInputStream fis = this.openFileInput("icon.png"); icon = Drawable.createFromStream(fis, "icon"); fis.close(); imageView.setImageDrawable(icon); thanks

• Why so many ASP.NET programmers play with Ruby on Rails after working hours?

  - by ITmeze

  I saw that on so many blogs. Lots of the people that were dealing with ASP.NET tend to play with Ruby on Rails after working hours. And It is just a matter of last one or two years. Why is it like that? Is it because when ASP.NET MVC showed up people become more open-minded - having joy with programming again they realize that some other folks had that many years ago, and they do not want to miss what they currently have?

• Does Core Data automatically validate new values when they are set?

  - by mystify

  In this question, someone asked how to write a validation method for Core Data. I did that, and it looks cool. But one thing doesn't happen: The validation. I can easily set any "bad" value and this method doesn't get called automatically. What's the concept behind this? Must I always first call the validation method before setting any value? So would I write setter methods which call the appropriate validation method first? And if yes, what's the point of following a strict convention in how to write the validation method signature? I guess there's also some automatic way of validation, then. How to activate this?

• What's the Erlang/Haskell job market like in the U.S.?

  - by Krystof

  I've heard that Telecoms are the big source of Erlang jobs but I'm not sure how much of a market there is. How likely is it that someone could find a job in Erlang/Haskell if they decided to learn it? In my case I have a lot of programming experience in Java but am tired of Java and want to try something different.

  I'm programming a function for a ti-nspire, so I can't use the builtins from inside a function. what is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)

• C++ Libraries similar to C#?

  - by cam

  I'm coming to C++ from a .Net background. Knowing how to use the Standard C++ Libraries, and all the syntax, I've never ventured further. Now I'm looking learning a bit more, such as what libraries are commonly used? I want to start getting into Threading but have no idea to start. Is there a library (similar to how .net has System.Threading) out there that will make it a bit easier? I'm specifically looking to do Linux based network programming.

• Revision, Quadratic Time

  - by stan

  I am not sure if you can post revision programming questions in here but i am stuck with some algorithms revision If an algorithm is quadratic it takes time proportional to the number of n^2 ? So if the slides say its almost 1/2 the square of n records is this the same as saying (n^2 * 0.5) Thanks

• How to implement a timer callback that executes in the same execution context

  - by Waldorf

  Some programming environments like C++ builder have timer components with a callback function which executes in the same execution contexts as where the timer object is created. I was wondering how to do something similar in plain c++ with threading. Or are there any other ways to have a callback which is periodically called to perform some task and runs in the same execution context as the calling thread?

• How i can i use the value of a variable from one class in another in objective c?

  - by user337174

  Hi i am fairly new to objective c and have been doing some iphone programming. Is it possible to look up the value of a variable in a different class? Basically what i am doing is running a function that exists in my app delegate from a view controller, but the app delegate needs to use a variable stored in the view controller from which the app delegate function was called. Make sense??? Any help would be grateful. James

• Is there an alternative for sleep() in C?

  - by Manoj Doubts

  In traditional embedded programming, we will give a delay function like so: for(i=0;i<255;i++) for(j=0;j<255;j++); In the microprocessor's view, is this how the sleep() function works? Is there an alternative for the sleep() function in C?
