• Is a commercial licensing tool better than a home grown solution for licensing a software product.

  - by Kalpak

  Hi, We are developing a product in C#.Net. We would definately not like our product to be copied easily across machines (in short pirated). For that purpose can anybody suggest using a 3rd party tool or a home grown solution. What are the pros and cons of each. One negative about home grown solution is that the cost involved in creating one from scratch. Can somebody comment on the technology to be used for licensing as .Net can be decompiled.

• What are the disadvantages of targeting the JVM instead of x86?

  - by Pindatjuh

  I'm developing a new language. My initial target was to compile to native x86 for the Windows platform, but now I am in doubt. I've seen some new languages target the JVM (most notable Scala and Clojure). Ofcourse it's not possible to port every language easily to the JVM; to do so may lead to small changes to the language and it's design. After posing this question, I even doubted more about this decision. I now know some "pro" JVM arguments. The original question was: is targetting the JVM a good idea, when creating a compiler for a new language? Updated the question: What are the disadvantages of targeting the JVM instead of x86 on Windows?

• C# - Realtime console output redirection

  - by Levo

  I'm developing a C# application and I need to start an external console program to perform some tasks (extract files). What I need to do is to redirect the output of the console program. Code like this one does not work, because it raises events only when a new line is writen in the console program, but the one I use "updates" what's shown in the console window, without writting any new lines. How can I raise an event every time the text in the console is updated? Or just get the output of the console program every X seconds? Thanks in advance!

• Field contains foreign IDs for different tables

  - by Rich

  I am developing a php/mysql driven facebook game. I am stuck on an element the table design. When a user completes a task I want to trigger any number of events. I was thinking of something like so: tbl_events *event_id - serogate primary ID *task_id - foreign ID of the task just completed *event_type - what type of event e.g is it a facebook stream publish or a message to the user or does it unlock a new element of the game? *event_param - this is where it gets tricky... the event parameter is a problem for two reasons, 1) it will contain different foreign ids... dependent on the event_type and thus it will not be possible to join to x table. Meaning I would have to call two queries. 2) Most events require a single id or text, however some events require multiple parameters - like the facebook stream publish.

• Bandwidth Monitoring in asp.net

  - by asifch

  HI, We are developing a multi-tenant application in Asp.Net with separate DB for each tenant, in which one of the requirement is to monitor the bandwidth usage for each tenant, i have tried to search but not found much help on the topic,we want to monitor exactly how much bandwidth is being used for each tenant while each tenant can have its own top level domain or a sub domain or a combination of both. so what are the available options, the ones which i can think of can be 1. IIS Log Monitoring means a separate application which will calculate the bandwidth for each tenant. 2. Log Each Request and Response for a tenant from within the application and then calculate the total bandwidth usage based on that. 3. Use some third part components if available So what do you think will be the best approach, also if there is any other way to do this.

• Is it a good practice to perform direct database access in the code-behind of an ASP.NET page?

  - by patricks418

  Hi, I am an experienced developer but I am new to web application development. Now I am in charge of developing a new web application and I could really use some input from experienced web developers out there. I'd like to understand exactly what experienced web developers do in the code-behind pages. At first I thought it was best to have a rule that all the database access and business logic should be performed in classes external to the code-behind pages. My thought was that only logic necessary for the web form would be performed in the code-behind. I still think that all the business logic should be performed in other classes but I'm beginning to think it would be alright if the code-behind had access to the database to query it directly rather than having to call other classes to receive a dataset or collection back. Any input would be appreciated.

• how to handle db concurrency in client-server application in C#?

  - by RAJ K

  I am developing an application in C# WPF which will have Client-Server architecture (Client will do products sales billing). I am novice in this area and I asked this question to start my development process. Click here to view question. So, ultimately I have selected MySQl, WCf & WPF. Now I have one silly question. Do i need to handle DB concurrency explicitly in my application (like 3 clients inserting data same time) or MySQl will handle this without any conflict? To accomplish my project i thought, I will create a service in WCf which will do DB queries from client application. Do you have any suggestion to improve my application performance.

• Python: How to run unittest.main() for all source files in a subdirectory?

  - by Pete

  I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

• Interacts with dialog/whiptail on early boot rcX.d stage?

  - by nm

  Hi buddies, I'm developing on Ubuntu based, actually I got one script in-charged on GUI(console) setup. It runs before another scripts (rcX.d) start. Currently, I installed this script on rc2.d and start earlier than other ones. But when run on real machine, I can't input any keystroke on "dialog --inputbox" or whiptail through shell script. Additionally, It runs well on my Virtual Machine (Virtual Box and Vmware), that's so strange! So, does anybody give some help or point me any clues for overcome this ? Thanks

• How to change security configutarion in IE8 for Intranet pages, such that Javascript can close a Win

  - by Martín Fixman

  I am developing a system that uses a little Internet page as a front-end for the whole program. Since I need to use ActiveX (sigh), the page must work on Internet Explorer. However, after some actions have been done the page needs to close itself. Using window.close() on Javascript it works, but before closing it prompts the user if it wants to close the Window. The ideal would be that it closes automatically. Is there any way to make IE8 (changing an option on the browser, not a code-only solution) not to prompt before closing the Window?

• Postpone email when domains equal

  - by michalzuber

  HI. For a client i'm developing 4 different email agents for his web portal. I need to send a lot of emails to clients (couple of thousands in the future) which are stored in a database. Sending is fine, but I would like to work out a PHP script which sends emails, but also stores the previous email domain and if they equal than postpone that email for sending later to prevent spam filters. I'm going to load that script with cron and I already set_time_limit(0); Big thanks for replies with ideas ;)

• What to do with lookup entities selected from drop down select ? How to send them to the service lay

  - by arrages

  I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

• starting a service based on someone's GPL/MIT licensed code

  - by fooyee

  someone wrote a nice framework for developing html5 3d engine. It's GPL/MIT licensed. Do you think it's a good idea to build upon it, and then repackage it and sell it as a service? For eg the framework lets you build 3d environments. so I build on it, maybe add a few features like characters and music in the environment, and turn it into an online game. Is it a feasible idea? Of course, part of the GPL license says that all source code has to be visible to end users. Assuming the web is a winner take all market based on first mover advantage, why care about hiding the source code? It's the product that's being sold that counts.

• frequently merge changes between branch and trunk?

  - by John

  My team and I are using svn branches for the first time. Before, we use to work only from the trunk. Over the past 2 weeks, we've been refactoring and developing new code against our branch. But during that time, another developer has been making bug fixes to code in the trunk and deploying it to the production server. We would like to frequently "update" our branch with changes from the trunk to make sure we get the latest fixes. But the problem is that we're making drastic changes to our branch, and many files have been renamed. I have a feeling every "update" we do on our branch that takes changes from trunk will cause a conflict, unless we some how get subversion to recognise that fileA.html in trunk is really fileB.html in branch. Am I using subversion branches correctly? Am I using the word "update" correctly? Are frequent "updates" in branch advisable?

• How to explicitly terminate http connection from server with no response header

  - by Gagandip

  I am developing a server simulator for one of my client application. I am using GlassFish server. I have to simulate a http connection terminate condition in my server application. Is there a way by which I can explicitly terminate a connection from server side such that client does not receive any response header. Currently I have tried many options like closing the response outputStream. But in every case a http 200 OK message is delivered to the client application. I would like to consume the http-request and do not want to return anything to the client. I am using a simple conrtroller servlet and had overridden doGet() and doPost() functions.

• Java Swing - How to access a JComponent of one JPanel from other JPanel, both added to the JFrame?

  - by Yatendra Goel

  I am developing a Java Desktop Application with GUI implemented in SWING. I hava a JFrame. I have added three JPanels on that. One JPanel panel1 has a Start Button. Now I want to disable various componets on other JPanels when a user presses the start button on the panel1. Now how can I access the components of those other panels from panel1. I know that one approach is to first get the container of panel1 panel1.getParent(); Then get the components of the container container.getComponents(); and use them as per need. Q1. Is there any other way by which I can perform the same task? (I think this is the only way) Q2. After getting the components list of the container, how to differentiate one container with other?

• How to enable an AdventureWorks database in a web application?

  - by salvationishere

  I am developing a C#/SQL ASP.NET web application in VS 2008. I want the users to be able to select an Adventureworks table and then an input file. The user is then able to map columns from the file with the selected table. This app works fine now in VS. But when I Browse in IIS, it doesn't show any of the tables. I think this is because currently Adventureworks connection string is integrated security (Windows authentication). If I want users to be able to select a table, do I have to change connection to SQL Server authentication? And if so, is the only way to do this to reinstall SQL Server? Or can I just reinstall Adventureworks? And if I reinstall SQL Server, do I need to reinstall VS also for this to work? This could be painful...

• Getting a Type variable knowing the name of type C#

  - by StuffHappens

  Hello! I'm developing a TypeTranslator class which has a method Type TranslateType(Type type). This method gets a type of an interface and if there's a class of interface name without leading I it creates it, otherwise an exception is raised. Here's some code to clearify what's written before: class Program { interface IAnimal { } class Animal : IAnimal { } void Function() { TypeTranslator typeTranslator = new TypeTranslator(); Assert(typeTranslator.TranslateType(typeof(IAnimal) == typeof(Animal))); } } Is it possible to get what I want? Thank you for your help!

• Should we be giving the client's management team direct access to our git hub repository so that the

  - by SharePoint Newbie

  Hi, We are presently working for a client who is new to working with distributed teams. We have teams spread across India and the UK. Although we have decent project tracking tools (Mingle), would it be a good idea to the give the PM at the client access to our git hub repo. Would this be make it easier for them (see what the devs are working on and an insight into what the team has been developing). I agree that noot all commit messages would make sense to them but would this be a good way to boost their confidence in what we are doing? They already can check out our fortnightly releases on our QA and UA environments, but this still is behind dev by 5-6 days. Also, is there any reporting for git hub which makes it easier for PM types to make sense of it all? Thanks
