Its all working so now I can chill

- by bizl

Most software houses I have been at have this attitude about their work. Get it done quick and move on. For programmers I find that the chill time is time that can be used to either improve infrastructure, refactor some old code or learn a new language. I would like to know what your throughts about 'chill time' if its the right attitude at all, and if so what to do with it. Is this sort of chilling helpful for a programmer, what are things you do with your own chill time if you adopt this approach to work.

How Do I Add Value To All Previous Values In Array

- by James

Lets say I have the following array: my_array = [1, 5, 8, 11, -6] I need to iterate over this array and add the values prior to the current value together. An example will probably be easier to understand. I need to return an array that should look something like this: final_array = [1, 6, 14, 25, 19] I have tried doing something like this: my_array.collect {|value| value + previous_values } But obviously that doesn't work because I can't figure out how to get the previous values in the array. I am a programming noob so this might be easier than I am making it. I am pretty sure I need to use either collect or inject, but I can't seem to figure out how to do this. Any help would be appreciated.

parse/collator for php

- by dramatic

I'm pretty much a newbie at php (at the "install an app and try to tweak it a bit" stage). Is there a tool anywhere which can take a script which is spread over many files and show you all the code which is processed (for a given set of arguments passed to the script) in a single output? For example, I want to make a call to zen cart from a script in a different language, which returns a category listing without any surrounding page. So I want to be able to trace what the actual process is to generate that then strip off all the unwanted bits to create a custom script.

Essential Training Topics for Supervisors of ASP.NET Developers

- by Dave Johnson

I have a co-worker who supervises a group of ASP.NET developers who are doing lots of ASP.NET/SQL Server apps. My co-worker was very technical at one time, but his last programming assignment was writing Fortran code in the 1980s. He has asked me to help him gain a deeper knowledge of ASP.NET Web application development to equip him in his supervisory role. I will be spending an hour every other week with him providing training, and he will probably not have a lot of time to commit otherwise. What would you recommend as topics to cover, tutorial resources, etc. so that I can help him get up to speed in his role as a supervisor of ASP.NET developers?

Methods to achieve first, previous, next and last navigation

- by Koroviev

I'm new to programming and have a question about navigation. What are the various methods that can achieve a "First", "Previous", "Next" and "Last" navigation, as seen in article or comic based sites? (Admittedly the "First" link isn't confusing as it can stay static, but what about the others?) For example, on the 50th page, the links would appropriately lead to the 49th and 51st (if it exists, if not it would not function but would automatically become active when such a page exists. In most examples of this I see urls ending with something like ".php?id=50" but am not certain how it's achieved, with a database? Any help will be very much appreciated, thanks.

Consolidate loan, purchase & sale tables into one transaction table.

- by Frank Computer

INFORMIX-SE with ISQL 7.3: I have separate tables for Loan, Purchase & Sales transactions. Each tables rows are joined to their respective customer rows by: customer.id [serial] = loan.foreign_id [integer]; = purchase.foreign_id [integer]; = sale.foreign_id [integer]; I would like to consolidate the three tables into one table called "transaction", where a column: transaction.trx_type char(1) {L=Loan, P=Purchase, S=Sale} identifies the transaction type. Each transaction will be assigned a unique transaction number [serial]. Is this a good idea or is it better to keep them in separate tables? Storage space is not a concern, I think it would be easier programming & user-wise to have all types of transactions under one table, whenever possible. This implies denormalization.

Using Jquery and Ajax in ASP.NET

- by xkcd

I am using ajax and jquery to load contents into a div. My jquery looks like this $("a.trigger").click(function() { $.ajax({ type: "POST", url: "GetStuff.aspx", data: "id=0", success: function(response){ $("#contentDiv").html(response); } }); }); In GetStuff.aspx I would like to write some asp.net html controls like private void Page_Load(object sender, System.EventArgs e) { Response.Expires = -1; Response.ContentType = "text/plain"; Response.Write("<asp:Label id=\"label1\" runat=\"server\" text=\"helloworld\"/>"); Response.End(); } However the label does not appear on the page. I tried to put the asp:Label in my aspx file like this <%@ Page Language="C#" Inherits="Untitled.GetStuff" %> <asp:Label id="label12" runat="server" text="helloworld2"/> It also does not work. How can I get asp.net html controls to show up?

Would you use Code Bubbles?

- by Paulo Santos

I've read this question mentioning Code Bubbles and I've watched their video presentation. The video is impressive, and does seem a little bit futuristic, but apparently it's somewhat real. But that kept me thinking... Would a developer really use such tool? We, as developers, are used to deal with code files, organizing them in directories, in one way or another, some common IDE (for those language that has them). It would be a great leap to use something like Code Bubbles, as they propose. I, personally, am not sure if I could work in such environment... although I think I would just need some adjusting... but I really don't see my mind working out the kinks of it. What are your thoughts on this?

Joining links together in a dictionary

- by ptabatt

Hi guys, I'm student here, new to python and programming in general. I have a dictionary links which holds a tuple mapped to a number. How can I join the second url in the second tuple together with the urljoin() function? What I'm trying to do is get complete links so I can run a recursive function search() which takes a complete url as an arguement, finds all the links in each url and stores the number of links mapped to the links in a database. So far, I have: links {('href', 'http://reed.cs.depaul.edu/lperkovic/csc242/test2.html'): 1, ('href', 'test3.html'): 1} I want http://reed.cs.depaul.edu/lperkovic/csc242/test3.html...

Screen scraping C application without using OCR or DOM?

- by Mrgreen

We have a legacy system that is essentially a glorified telnet interface. We cannot use an alternative telnet client program to connect to the system since there are special features built into the client software they have provided us. I want to be able to screen scrape from this program, however that's proving very difficult. I have tried using WindowSpy and Spy++ to check the window text and it comes up blank. It's a custom C program written by the vendor (they have even disabled selecting text). I'm really looking for a free option and something I may perhaps be able to use in conjuction with a scripting language. It seems the only ways to grab text is directly from the Windows GDI or from memory, but that seems a little extreme. Can anyone recommend any software/DLLs that might be able to accomplish this? I'd be extremely appreciative.

Pseudo Transparant images

- by Samuel

Hello World! For an assignment at university we program in a pretty unknown language Modula 2, which lacks major graphic support. I was wondering how to achieve a 'transparency' effect on images, i figured it would work like this: Create a 2D array for the background area of the image filled with the colours of the different pixels in that area, create another 2D array of the image with again the colours of every picture and than merge the pixel colours and draw the different "new colours" on their appropriate place. What i was wondering about: how do i merge the colours (hexadecimals) just: ( colour1 + colour2 ) / 2 ? Thanks for your help!!

When to databind data-bound controls?

- by sanjuro

Hi, i have little dilemma, i often use data-bound controls such as Gridview in conjunction with ObjectDataSource. But i have two possible options when can i bind data to Gridview. The first is that i set datasourceid of gridview in aspx file and databind occurs in a moment before PreRender event occurs or i can set datasource in Page_Load event and databinding occurs immediately, something like this: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { testGridView.DataSource = testObjectDataSource.Select(); testGridView.DataBind(); } } I think that in second approach i have more control above databinding. But how it is in real programming life? Which of the above two options is commonly used? Or is there some third option how can i bind data to data-bound control? Thanks for your opinions from real-life experiences.

How to signal a buffer full state between posix threads

- by mikip

Hi I have two threads, the main thread 'A' is responsible for message handling between a number of processes. When thread A gets a buffer full message, it should inform thread B and pass a pointer to the buffer which thread B will then process. When thread B has finished it should inform thread A that it has finished. How do I go about implementing this using posix threads using C on linux. I have looked at conditional variables, is this the way to go? . I'm not experienced in multi threaded programming and would like some advice on the best avenue to take. Thanks

Getting SQL Server Compact 4.0 Tools CTP2

- by sinni800

Hello. I'm currently trying to install the "new" Microsoft WebMatrix Beta 2 (a web programming IDE). I was trying to use Web Platform Installer for this. But it 404's on the SQL Compact 4.0 CPT2 and it's tools. I was able to get the runtime from the Microsoft downloads page but the tools I am not able to find. I can not install WebMatrix because the tools are a prerequisite. Does anybody know where to get them from now?

Designing software interface for various screen sizes

- by Tower

Hi, Nowadays we have screens like 1920x1200 and 1680x1050 in popular use and some even use 2560x1600 resolution while some older systems still rely on a 800x600 resolution. I am writing a software that looks good on a 1680x1050, but too small on a 1920x1200 and too large on a 1024x768. Do you have suggestions how to go for designing an application for various screen sizes? Things were a lot simpler before when we had little differences in resolutions, but now it seems there's no good way of handling this. I know this question is more about designing / layout than programming, but I bet this is more or less part of programmers life so I made this post here.

.NET --- Textbox control - wait till user is done typing

- by Cj Anderson

Greetings all, Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. I have some ideas floating around my head but I'm sure they aren't the most efficient. Like measuring the time since the last textchange event and if it was than a certain value then it would proceed to run the rest of my procedures. let me know what you think. Language: VB.NET Framework: .Net 2.0 --Edited to clarify "done typing"

Are there any layout comparison / vssetting sharing places?

- by Wil

Well, I reinstalled Visual Studio 2008 and did not have a backup of my vssetting file. I did not think it was that important as I had barely customised it, however it just doesn't feel right! The general windows feel correct but When I switch between views (source code, Windows forms, web editor), all the toolbars get muddled up. In the past few years, I have seen so many "post your desktop" type items and I could swear there there would be some "post your IDE", but after looking on Google and several other programming sites, I just can't find one! I don't want this turning in to a post your IDE unless others want to, but can anyone point me to a site where they have done this, or even better - are there any vssetting sharing places where you can download ones made by others?

Looking to eventually build a smartphone app...

- by Brian L

Hi all- I'm a young, inexperienced programmer (I've had a year of Java, some MATLAB, and HTML/CSS in school) but I've decided that to get better, I'm making it my goal to produce a simple smartphone app of some kind this year- probably either webOS or Android since I'm on a PC and can't afford a Mac just to write an iPhone app. So my question is, where do I start? I've read the threads about How to Write for Android and such, but I'm not sure I have enough Java experience to just jump right in. And then there's webOS which is based on JavaScript, correct? I guess I'd just like some input from more experienced folks. I have some Barnes and Noble book credit I'm looking to get rid of too, so if there's a guide you think would be useful, feel free to request. tl;dr: Programming newbie ultimately wants to build a simple smartphone app. Where do I start?

how sort recursively by maximum fileze and counts files type?

- by user599395

Hello! I'm beginner in bash programming. I want to display head -n $1 results of sorting files by size in /etc/*. The problem is that at final search, I must know how many directories and files has processed. I compose following code: #!/bash/bin let countF=0; let countD=0; for file in $(du -sk /etc/* |sort +0n | head $1); do if [ -f "file" ] then echo $file; let countF=countF+1; else if [ -d "file" ] then let countD=countD+1; fi done echo $countF echo $countD I have errors at execution. How use find with du, because I must search recursively?

Foreach File in a Folder in Flash?

- by msandbot

Hey, I have an image slideshow program working right now and it takes in a folder of a hard coded in number of images. I would like to change this so that it can take in a folder and will display all of them no matter the number. Is there a way to do this in flash? I'm thinking something like the foreach loop in perl or other scripting language. It is possible to store then number of images in a text file but I also don't know how to read that in flash either. I'm working in actionscript 3. Any help would be greatly appreciated. Thanks -Mike

How to remove svn folders over FTP on Windows hosting

- by Loftx

Hi there, I've accidentally copied a large part of a folder tree from my SVN working copy to my shared Windows web host via FTP. The site is now littered with .svn directories and and I need some way of cleaning them. The only access I have to the server is via FTP, or by running a script on the server. Does any one have a script which can be run remotely to remove the files over FTP from my development machine (any language Windows/Linux is fine) or a script in ASP, ASP.net or PHP I can run directly on the Windows server to remove these directories? Thanks, Tom

Refreshing metadata on user functions t-SQL

- by luckyluke

I am doing some T-SQL programming and I have some Views defines on my database. The data model is still changing these days and I have some table functions defined. Sometimes i deliberately use select * from MYVIEW in such a table function to return all columns. If the view changes (or table) the function crashes and I need to recompile it. I know it is in general good thing so that it prevents from hell lotta errors but still... Is there a way to write such functions so the dont' blow up in my face everytime I change something on the underlying table? Or maybe I am doing something completely wrong... Thanks for help
