  • a simple program that counts and sums digits. How can I make it work?

    - by user1710386
    So I've to write a simple program(that loops) where you can enter an int and it spews out the number count and the sum of the numbers. Since I am such a tard when it comes to programming, I just scavanged the code online and tried to piece it together. I guess the sum block screws with n, but I am not really sure. Anyway, I would really appreciate it if somebody could point out mistakes and show me how can I make it work. #include <iostream> using namespace std; int main() { while(1) { int i,p,n,sum=0; //sum block cout<<"enter an int: "; cin>>n; { while(n!=0) { p=n % 10; sum+=p; n=n/10; } cout<<"int digit sum: "<<sum <<endl; } { int count = 0; while(n) { n /= 10; ++count; } cout <<"number of digits: " << count << '\n';} } }

  • Are there really safe and legal resources for sound effects to use in applications?

    - by mystify
    For those who want to opt for "close" immediately: Great user interfaces need great sound effects, right? User interfaces are programmed by programmers, right? So this is a programming question, ok? I had a very hard time to find good and legal sound resources. I am not looking for free sounds. Proper licensing is absolutely crucial, and I don't want to get sued by multibilliondollar music companies, hollywood sound studios and their highly overpaid lawyers. They cry about people downloading their stuff in file sharing sites but when someone comes and wants to really license stuff, the market is so empty like an open and unwatched gold mine. Trust me, whatever I type into google, I always end up getting sort of opaque and strange music libraries that do charge money, but refuse to provide proper licensing evidence to the licensee. When you pay money and they only count how many files you downloaded, that can never be a valid license, nor any evidence for you that you did license the sounds. Imagine that contributor suing you and you say: "I licensed it at xy", and his lawyer just smiles: "Show me proof, mofo!". So you loose a million dollars, or 1 for every downloaded app. Congrats. But that's the way all those "hey we're the worlds largest sound effect library" libraries are doing it. It's really annoying. And I hope someone here is able to point out a sound effects ressource which is A) big B) used by professinals C) has a reasonable pricing and licensing model D) provides the licensee with proper legal evidence about licensed sounds You know, I'm not from the US and typically you US folks are the ones who invent the cool stuff on the net, and maybe I just missed a new great start up. So?

  • Stopping at my Front-End abilities... good career move?

    - by R. H.
    Just curious about what other front-end and back-end people think, career wise. Here's the details: I'm a 30 yr old mom who is pretty good at front end development - that's my day job at an interactive agency. Don't have the money or time to go back to school or lots of high priced training sessions. I started out as a graphic designer ten years ago or so, then moved into database-backed web stuff, like CMS. I'm great at transforming PSD to a working html and css structure, especially for Wordpress themes. I enjoy this part of the process, probably because it's easy and fun, and as I learn a little more about jQuery and PHP, I can make it even better if I want or need. I'm not sure where I should stop though, as far as my career goes. I don't know that I'll ever get to the point that I'm a great PHP developer or jQuery master. Is it lame to just be a front-end designer/developer? Can that be a successful career all its own? Or, should I obligate myself to learning the harder programming, if I'm capable? Any advice or points any of you may have is appreciated!

  • When to use pointer to a class and when to just instantiate it as a variable

    - by Enders
    Im sort of confused by it. The best I could find was reading through the cplusplus.com tutorial and all they have to say about pointers to classes. "It is perfectly valid to create pointers that point to classes. We simply have to consider that once declared, a class becomes a valid type, so we can use the class name as the type for the pointer" Which tells me nothing about when to use them over the normal instantiation. I've seen the - operator many times, and looked at some codes but cant really decipher why they did it. Generic examples will be appreciated; but more specifically related to gui programming. Its where I encountered it first. QGridLayout *mainLayout = new QGridLayout; mainLayout->addWidget(nameLabel, 0, 0); mainLayout->addWidget(nameLine, 0, 1); mainLayout->addWidget(addressLabel, 1, 0, Qt::AlignTop); mainLayout->addWidget(addressText, 1, 1); Why not QGridLayout mainLayout mainLayout.addWidget ... (It doesnt compile if I change the sample code to that and try it but you get the point) Thanks in advance

  • Solutions to cubefarm lighting

    - by Khorkrak
    So with our recent move to the cubefarm out from our developer friendly shared office, we've altered the environment to reproduce our more programming conducive workspace as much as possible. Fortunately, we we're planted into the same aisle as QA. They're quiet and it's made it easier to pair up to review a problem. They've already unscrewed some of the fluorescent bulbs. We unscrewed the rest. Now the facilities coordinator and HR are wondering what to do. They want the office to have an open, bright and elegant feel to it as does the founder - think IKEA. Fortunately he's usually in the NYC office and rarely stops up where we work. There's some natural light from nearby windows and translucent office walls that ring the farm. So the facility coordinator doesn't understand - do you guys want incandescents overhead or... no we just don't want overhead lights. How to solve this while avoiding having a weird looking office space with a dark spot in the middle. Are there any better solutions - no we can't have an office as that's considered a management only perk.

  • Where do you use Java code? Trouble sending .jar files

    - by leigero
    Apologies for the generic nature of this question. I have been learning Java for a few months now, and I've created a few simple projects which have some functionality. I wanted to send the projects to a friend and I'm running into countless errors and struggles. Passing a .jar file is causing "Main class not found" errors when they try to open it. I tried using third party software to wrap the .jar files into an .exe file and the same errors still persist. Beyond that, I'm convinced that passing around .jar files wrapped into .exe files via third party software is NOT how Java was intended to be used. I've read two books on Java and they all talk about structuring the language, but I'm confused about WHERE I'm supposed to be using this code because it has become painfully obvious that it is NOT intended to be passed around in file format. Is this a server programming language? Used on the back end of websites mainly? I'm not sure where one would be using the code written in Java.

  • Many tables for many users?

    - by Seagull
    I am new to web programming, so excuse the ignorance... ;-) I have a web application that in many ways can be considered to be a multi-tenant environment. By this I mean that each user of the application gets their own 'custom' environment, with absolutely no interaction between those users. So far I have built the web application as a 'single user' environment. In other words, I haven't actually done anything to support multi-users, but only worked on the functionality I want from the app. Here is my problem... What's the best way to build a multi-user environment: All users point to the same 'core' backend. In other words, I build the logic to separate users via appropriate SQL queries (eg. select * from table where user='123' and attribute='456'). Each user points to a unique tablespace, which is built separately as they join the system. In this case I would simply generate ALL the relevant SQL tables per user, with some sort of suffix for the user. (eg. now a query would look like 'select * from table_ where attribute ='456'). In short, it's a difference between "select * from table where USER=" and "select * from table_USER".

  • Looking for a good C++/.net book

    - by Michael Minerva
    I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

  • Why do my debugger randomly jump out of debug mode?

    - by Clean
    Hi, I'm experiencing a very annoying behavior with the debugger in Visual Studio 2008 Professional. I'm debugging a ASP.NET web application, and when stepping through the code the debugger randomly "jumps out" of debug mode, but without the debugger stopping. So when I'm stepping through my code like this: step over, step over, step over, step over, ... , step over The debugger continues as If I was pressing Continue, like this: step over, step over, step over, step over, ... , continue Thing is, I never touch continue! So, the debugger is still running, the ASP.NET page renders, but my "stepping" ends. This is of course very annoying. And it happens totally randomly. Before switching to Windows 7 and IIS 7.5, I've never experienced this problem. My colleague who debugs the exact same code, but on a Windows XP machine running IIS 6 have never had this problem either. So my thought is, perhaps this is Windows 7 or IIS 7.5 related? I've already made sure <compilation defaultLanguage="c#" debug="true" /> is set in web.config. Have anyone experienced the same problem, or perhaps have an idea why I'm experiencing this annoying behavior? Thanx! P.S I realize this question might be more Visual Studio 2008 specific rather than programming specific, but I figure my best chance to find somebody that experienced the same problem would be at a forum for programmers (since naturally, programmers are the most frequent users of Visual Studio 2008).

  • How do I subtract two dates in Django/Python?

    - by Ryan
    Hi! I'm working on a little fitness tracker in order to teach myself Django. I want to graph my weight over time, so I've decided to use the Python Google Charts Wrapper. Google charts require that you convert your date into a x coordinate. To do this I want to take the number of days in my dataset by subtracting the first weigh-in from the last weigh-in and then using that to figure out the x coords (for example, I could 100 by the result and increment the x coord by the resulting number for each y coord.) Anyway, I need to figure out how to subtract Django datetime objects from one another and so far, I am striking out on both google and here at the stack. I know PHP, but have never gotten a handle on OO programming, so please excuse my ignorance. Here is what my models look like: class Goal(models.Model): goal_weight = models.DecimalField("Goal Weight",max_digits=4, decimal_places=1) target_date = models.DateTimeField("Target Date to Reach Goal") set_date = models.DateTimeField("When did you set your goal?") comments = models.TextField(blank=True) def __unicode__(self): return unicode(self.goal_weight) class Weight(models.Model): """Weight at a given date and time """ goal = models.ForeignKey(Goal) weight = models.DecimalField("Current Weight",max_digits=4, decimal_places=1) weigh_date = models.DateTimeField("Date of Weigh-In") comments = models.TextField(blank=True) def __unicode__(self): return unicode(self.weight) def recorded_today(self): return self.date.date() == datetime.date.today() Any ideas on how to proceed in the view? Thanks so much!

  • Thread is being killed by the OS

    - by Or.Ron
    I'm currently programming an app that extracts frames from a movie clip. I designed it so that the extraction will be done on a separate thread to prevent the application from freezing. The extraction process itself is taking a lot of resources, but works fine when used in the simulator. However, there are problems when building it for the iPad. When I perform another action (I'm telling my AV player to play while I extract frames), the thread unexpectedly stops working, and I believe it's being killed. I assume it's becauase I'm using a lot of resources, but not entirely sure. Here are my questions: 1. How can I tell if/why my thread stopping? 2. If it's really from over processing what should I do? I really need this action to be implemented. Heres some code im using: To create the thread: [NSThread detachNewThreadSelector:@selector(startReading) toTarget:self withObject:nil]; I'll post any information you need, Thanks so much! Update I'm using GCD now and it populates the threads for me. However the OS still kills the threads. I know exactly when is it happening. when i tell my [AVplayer play]; it kills the thread. This issue is only happening in the actual iPad and not on the simulator

  • Reference remotely located assembly (web uri) from locally installed application?

    - by moonground.de
    Hi Stackoverflowers! :) We have a .NET application for Windows which is installed locally by Microsoft Installer. Now we have the need to use additional assemblies which are located online at our Web Servers. We'd like to refer to a remote uri like https://www.ourserver.com/OurProductName/ExternalLib.dll and reveal additional functionality, which is described roughly by a known common ("AddIn/Plugin") Interface. These are not 3rd Party Plugins, we just want be able to exchange parts of the application frequently, without the need to have frequent software updates. Our first idea was to add some kind of "remote refence" in Visual Studio by setting the path to the remote assembly uri. But Visual Studio downloaded the assembly immediately to a temporary directory, adding a reference to it. Our second attempt then, is simply using a WebRequest (or WebClient) to retrieve a binary stream of the Assembly, loading it "from image" by using Assembly.Load(...). This actually works, but is not very elegant and requires more additional programming for verification etc. We hoped Clickonce would provide useful techniques but apparently it's suitable for standalone applications only. (Correct me?) Is there a way (.net native or by framework/api) to reference remotely located assemblies? Thanks in advance and have a happy easter!

  • Please help me optimize my Python code

    - by Haidon
    Beginner here! Forgive me in advance for raising what is probably an incredibly simple problem. I've been trying to put together a Python script that runs multiple find-and-replace actions and a few similar things on a specified plain-text file. It works, but from a programming perspective I doubt it works well. How would I best go about optimizing the actions made upon the 'outtext' variable? At the moment it's basically doing a very similar thing four times over... import binascii import re import struct import sys infile = sys.argv[1] charenc = sys.argv[2] outFile=infile+'.tex' findreplace = [ ('TERM1', 'TERM2'), ('TERM3', 'TERM4'), ('TERM5', 'TERM6'), ] inF = open(infile,'rb') s=unicode(inF.read(),charenc) inF.close() # THIS IS VERY MESSY. for couple in findreplace: outtext=s.replace(couple[0],couple[1]) s=outtext for couple in findreplace: outtext=re.compile('Title: (.*)', re.I).sub(r'\\title'+ r'{\1}', s) s=outtext for couple in findreplace: outtext=re.compile('Author: (.*)', re.I).sub(r'\\author'+ r'{\1}', s) s=outtext for couple in findreplace: outtext=re.compile('Date: (.*)', re.I).sub(r'\\date'+ r'{\1}', s) s=outtext # END MESSY SECTION. outF = open(outFile,'wb') outF.write(outtext.encode('utf-8')) outF.close()

  • Writing a report

    - by wvd
    Hello all, Since some time I've been investigating more time into profiling things better, really think about how to do a thing and why. Now I'm going to start a new project, where I will be writing a report about. The report will be about anything what I wrote in the project, why, and I'll be investigating some things and do particular research about them. I've seen some reports, such as game programming in Haskell using FRP. However, after reading several reports they all seem to be build different. I have a few questions about writing a report: 1] What are the things I really should include, and what are the things I really shouldn't include? 2] Is it useful to include graphs about different methods/approaches to a several problem, where you only included one into your project, to show WHY you didn't include the other methods. Or should I just explain the method/approach used into the project. 3] Should I only be writing the report after I've completed the project, or should I also write pages about what I expect, how I'm going to build the software? Thanks, William van Doorn

  • Return value of a JQuery autocomplete using an array of objects as its source

    - by user2920430
    In a JQuery autocomplete which uses an array of objects as its source, can I display the label in the INPUT and later access the value? The default behavior is that the value is displayed in the INPUT after selection. In this case the values represent indexes to unique keys in rows in a table. <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>autocomplete demo</title> <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css"> <script src="http://code.jquery.com/jquery-1.9.1.js"></script> <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script> </head> <body> <label for="autocomplete">Select a programming language: </label> <input id="autocomplete"> <script> $( "#autocomplete" ).autocomplete({ source: [ { label:"c++", value:1 }, { label: "java", value:2 }, { label: "javascript", value:3 } ] }); </script> </body> </html>

  • int array doesnt get char values

    - by user1780004
    I am absolutely brand new at programming and im not sure how to explain what im doing here. The whole purpose of this piece is to enter values and then print them out in the same order. Now I wanna quit from entering values when pressing 'q' and so I have to scanf for chars but when I assign them back to the int array the values are not the same. Hope that makes any sense to you but in any case heres my code: #include <stdio.h> #include <stdlib.h> #define SIZE 5000 define flush fflush(stdin) main() { int input[SIZE] = {0},i = 0; int counter = 0; char inputs, quit; do { system("cls"); printf("Input number ('q' to quit and display numbers entered): "); flush; scanf("%c",&inputs); flush; if (inputs == 'q') quit = 'q'; else { input[i] = inputs; counter++; i++; } } while (i < SIZE && quit != 'q'); for(i = 0; i < counter; i++){ printf("%i.%i\n", i + 1, input[i]); } system("pause"); } Ive been trying to do this on my own btw and also researched some information online regarding chars but couldnt find anything that would help me. Thanks a lot in advance.

  • [C++] Trouble declaring and recognizing global functions

    - by Sarah
    I've created some mathematical functions that will be used in main() and by member functions in multiple host classes. I was thinking it would be easiest to make these math functions global in scope, but I'm not sure how to do this. I've currently put all the functions in a file called Rdraws.cpp, with the prototypes in Rdraws.h. Even with all the #includes and externs, I'm getting a "symbol not found" error at the first function call in main(). Here's what I have: // Rdraws.cpp #include <cstdlib> using namespace std; #include <cmath> #include "Rdraws.h" #include "rng.h" extern RNG rgen // this is the PRNG used in the simulation; global scope void rmultinom( double p_trans[], int numTrials, int numTrans, int numEachTrans[] ) { // function 1 def } void rmultinom( const double p_trans[], const int numTrials, int numTrans, int numEachTrans[]) { // function 2 def } int rbinom( int nTrials, double pLeaving ) { // function 3 def } // Rdraws.h #ifndef RDRAWS #define RDRAWS void rmultinom( double[], int, int, int[] ); void rmultinom( const double[], const int, int, int[] ); int rbinom( int, double ); #endif // main.cpp ... #include "Rdraws.h" ... extern void rmultinom(double p_trans[], int numTrials, int numTrans, int numEachTrans[]); extern void rmultinom(const double p_trans[], const int numTrials, int numTrans, int numEachTrans[]); extern int rbinom( int n, double p ); ... int main() { ... } I'm pretty new to programming. If there's a dramatically smarter way to do this, I'd love to know.

  • Obj-C Sending Messages Between Classes

    - by user544359
    I'm a newbie in iPhone Programming. I'm trying to send a message from one view controller to another. The idea is that viewControllerA takes information from the user and sends it to viewControllerB. viewControllerB is then supposed to display the information in a label. viewControllerA.h #import <UIKit/UIKit.h> @interface viewControllerA : UIViewController { int num; } -(IBAction)do; @end viewControllerA.m #import "viewControllerA.h" #import "viewControllerB.h" @implementation viewControllerA - (IBAction)do { //initializing int for example num = 2; viewControllerB *viewB = [[viewControllerB alloc] init]; [viewB display:num]; [viewB release]; //viewA is presented as a ModalViewController, so it dismisses itself to return to the //original view, i know it is not efficient [self dismissModalViewControllerAnimated:YES]; } - (void)dealloc { [super dealloc]; } @end viewControllerB.h #import <UIKit/UIKit.h> @interface viewControllerB : UIViewController { IBOutlet UILabel *label; } - (IBAction)openA; - (void)display:(NSInteger)myNum; @end viewControllerB.m #import "viewControllerB.h" #import "viewControllerA.h" @implementation viewControllerB - (IBAction)openA { //presents viewControllerA when a button is pressed viewControllerA *viewA = [[viewControllerA alloc] init]; [self presentModalViewController:viewA animated:YES]; } - (void)display:(NSInteger)myNum { NSLog(@"YES"); [label setText:[NSString stringWithFormat:@"%d", myNum]]; } @end YES is logged successfully, but the label's text does not change. I have made sure that all of my connections in Interface Builder are correct, in fact there are other (IBAction) methods in my program that change the text of this very label, and all of those other methods work perfectly... Any ideas, guys? You don't need to give me a full solution, any bits of information will help. Thanks.

  • issue with tab bar view displaying a compound view

    - by ambertch
    I created a tab bar application, and I make the first tab a table. So I create a tableView controller, and go about setting the class identity of the view controller for the first tab to my tableView controller. This works fine, and I see the contents of the table filling up the whole screen. However, this is not what I actually want in the end goal - I would like a compound window having multiple views: - the aforementioned table - a custom view with data in it So what I do is create a nib for this content (call it contentNib), change the tab's class from the tableView controller to a generic UIViewController, and set the nib of that tab to this new contentNib. In this new contentNib I drag on a tableView and set File's Owner to the TableViewController. I then link the dataSource and delegate to file's owner (which is TableViewController). Surprisingly this does not work and I receive the error: **Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x3b0f910'** This is bewildering to me since the file's owner is the TableViewController, which has been assigned to be both the dataSource and delegate. Does someone have either insight into my confusions, or a link to an example of how to have a compound view include a tableView? *update* I see this in the Apple TableView programming guide: "Note: You should use a UIViewController subclass rather than a subclass of UITableViewController to manage a table view if the view to be managed is composed of multiple subviews, one of which is a table view. The default behavior of the UITableViewController class is to make the table view fill the screen between the navigation bar and the tab bar (if either are present)." <----- I don't really get what this is telling me to do though... if someone can explain or point me to an example I'd be much appreciated!

  • Why is my php script freezing?

  • Faster or more memory-efficient solution in Python for this Codejam problem.

    - by jeroen.vangoey
    I tried my hand at this Google Codejam Africa problem (the contest is already finished, I just did it to improve my programming skills). The Problem: You are hosting a party with G guests and notice that there is an odd number of guests! When planning the party you deliberately invited only couples and gave each couple a unique number C on their invitation. You would like to single out whoever came alone by asking all of the guests for their invitation numbers. The Input: The first line of input gives the number of cases, N. N test cases follow. For each test case there will be: One line containing the value G the number of guests. One line containing a space-separated list of G integers. Each integer C indicates the invitation code of a guest. Output For each test case, output one line containing "Case #x: " followed by the number C of the guest who is alone. The Limits: 1 = N = 50 0 < C = 2147483647 Small dataset 3 = G < 100 Large dataset 3 = G < 1000 Sample Input: 3 3 1 2147483647 2147483647 5 3 4 7 4 3 5 2 10 2 10 5 Sample Output: Case #1: 1 Case #2: 7 Case #3: 5 This is the solution that I came up with: with open('A-large-practice.in') as f: lines = f.readlines() with open('A-large-practice.out', 'w') as output: N = int(lines[0]) for testcase, i in enumerate(range(1,2*N,2)): G = int(lines[i]) for guest in range(G): codes = map(int, lines[i+1].split(' ')) alone = (c for c in codes if codes.count(c)==1) output.write("Case #%d: %d\n" % (testcase+1, alone.next())) It runs in 12 seconds on my machine with the large input. Now, my question is, can this solution be improved in Python to run in a shorter time or use less memory? The analysis of the problem gives some pointers on how to do this in Java and C++ but I can't translate those solutions back to Python.

  • Android 2.0+ account duplication

    I know that you can setup accounts in Android 2.0+ and thats great but as i have recently found out, it can create duplication. My phone(Sprint HTC hero 2.1-upadate1) comes with HTC Sense and thats great, it also has Peep pre-installed and it asked me when i setup the phone to add a twitter account, and so i did. I can now open peep and it all works, perfect. But I decided i wanted to try the Twitter for Android app. I installed it and it also asked me to create a twitter account, not good. I did create the new account and the app worked just like it was supposed to. Then when i go into my accounts i can see that i have two twitter accounts(the same one). Is this something that can be avoided in the programming or is this something that can be fixed with the os? I also noticed the same for the facebook account. Is there something in the SDK that can prevent this...or combine the accounts after the fact? or is this all completely up to the developers. If its up to the developers then i would really like to see some code/documentation so i can avoid such things.

  • In C, when do structure names have to be included in structure initializations and definitions?

    - by Tyler
    I'm reading The C Programming Language by K&R and in the section on structures I came across these code snippets: struct maxpt = { 320, 200 }; and /* addpoints: add two points */ struct addpoint(struct point p1, struct point p2) { p1.x += p2.x; p1.y += p2.y; return p1; } In the first case, it looks like it's assigning the values 320 and 200 to the members of the variable maxpt. But I noticed the name of the struct type is missing (shouldn't it be "struct struct_name maxpt = {320, 200}"? In the second case, the function return type is just "struct" and not "struct name_of_struct". I don't get why they don't include the struct names - how does it know what particular type of structure it's dealing with? My confusion is compounded by the fact that in previous snippets they do include the structure name, such as in the return type for the following function, where it's "struct point" and not just "struct". Why do they include the name in some cases and not in others? /* makepoint: make a point from x and y components */ struct point makepoint(int x, int y) { struct point temp; temp.x = x; temp.y = y; return temp; }

  • How to be a better software designer

    - by Bmw
    I feel as if I am a hack programmer. I do things over and over again until they finally work. I copy/paste code. I don't think about why something makes sense, if it works I go with it. I have my undergraduate in computer science, and I've done this the entire time. Somehow I made it through the degree by doing this and now I'm in my second year of programming professionally and I am still able to do this and get away with it. Here's the thing, I don't want to be this way anymore. I am not proud of the work I do, I feel like I'm just a copy/paste programmer. How do I become better? I want to be able to design something on my own without copying code. Have you ever been in this situation, if so how did you move beyond it to become a better programmer? To add some background about myself, I started as an asp.net c# programmer, now I'm doing vbscript (which actually makes my tendency to copy/paste/hack a lot worse I must say!) with classic asp…
