  • Sending SMS using Java ME application

    - by iamrohitbanga
    I want to a Java ME application that transfers any SMS received to a PC using bluetooth. The PC can then direct the Java ME application via bluetooth to send a response SMS. Is there library available for this architecture or I have to design it myself? Is this approach correct or a better one exists? I want to use bluetooth as then I will not have dependency on the cable.

  • Is the offical Sun Java EE tutorial the best way to learn how to make Java web apps?

    - by Nick
    I've been a web developer for almost a decade. I've mostly used classic ASP/JavaScript and I'd like to move into Java based apps. I have a decent understanding of Java itself (enough to know how to lookup what I don't know) and I spent some time doing minor work on a JSF/Spring/Hibernate app, but from what a trusted coworker told me, this application is the example of what not to do. I want to learn the really hardcore stuff (EJBs, HA Clustering, etc), but I know I have to walk before I can run. Is the Sun Tutorial the best place to start? Or is there an definitive book (like K&R for C or Gang of Four for design patterns) that I should buy?

  • Win2k3 password Authentication using LDAP in VC++

    - by user001
    Hi, I need to implement the Win2k3 password validation policy. As my application resides on Win2k3 cane we validate the password directly with windows domain password by using LDAP. This is because application design does not want to store 8/more password entry into DB and validate new password against that. As Windows already does same thing and using LDAP we can lookup into windows server. Can any one please let me know LDAP API to fulfill above requirement in VC++.

  • How can I avoid causing memory leaks in Firefox?

    - by mrdanimal
    It seems that there is a lot of information on memory leaks in IE and how web developers can avoid them, but I can't find much on avoiding leaks in FF. I've found lots of random tips on how end users can tweak their preferences, or tips for extension developers, but little on what I can do as a web developer to make sure my pages don't leak. Am I missing something? It seems lazy to just blame it on the user and say "you've got too many extensions". Or are the major patterns the same as in IE -- circular references and all that? Also, if anyone knows of any tools to troubleshoot leaks in FF, that would be great. I found this: https://addons.mozilla.org/en-US/firefox/addon/2490/ But it's apparently just for chrome and extension development.

  • Free UI tools for Cappuccino?

    - by avp
    Hi, I'm looking for free tools to design the UI for my web app. I'm pretty new to this field, so please point me to acceptable solutions. Basically, I need to fill a "screen" with some controls, that's it. Thanks. EDIT: Well, as soon as nobody answers, maybe somebody can help me with this problem for some framework other than Cappuccino?

  • No IO exception reported for socket operation when the interface is removed

    - by user352536
    The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?

  • Working with three dimensional data in an HTML (ASP.NET) table.

    - by ProfK
    I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions). Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid. I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc. Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?

  • Can a program have a few IFs and only one Else structures?

    - by kwokwai
    Hi all, When I was doing some JQuery and PHP, I noticed the If-else patterns were treated differently and varied from one language to another. Say I got a simple input text field in a HTML and I was using some Ifs and Elses to check the value input into the text field. Text: <input type="text" name="testing"/> In JQuery, I got some codes as follows: if($("#testing").val()==1){ //do something } if($("#testing").val()=="add"){ //do something } else{ //do something } if($("#testing").val()=="hello"){ //do something } How come JQuery and PHP treated the Else statement differently? I mean in JQuery, the third If statement was still proceeded even if it had gone to the Else statement, but it stopped after the Else statement when I repeated the code in PHP script.

  • Can I get a WPF ListBox to inherit brushes from parent element?

    - by Jay
    My WPF window has its foreground brush set to a brush from a resource dictionary, and I want all text in the window to have this color, so I don't touch the foreground brush in anything else. Textboxes get the color Textblocks get the color Buttons get the color Listboxes do not get the color, and so neither do their contents. Is there any way to get a Listbox to behave like the other controls in this respect? Assuming not, and that this is by design, what is the rationale?

  • SMS + Web app: Providers of SMS "Long codes" for use by U.S. carrier subscribers within U.S.?

    - by fourh
    Q.: How to get a cellular phone SMS "Long code" for use by U.S. carrier subscribers within U.S.? Background: I'm building a web app that receives queries from/sends answers to cell phones. The app design (and business model) expects to communicate with cell devices via SMS, addressing the web app via an SMS "Long code" (VMN or MSISDN). The mobile phone subscribers will be sending/receiving within the U.S. and using U.S. carriers. Long codes are not available within the U.S. cellular services.

  • Python style: if statements vs. boolean evaluation

    - by mkscrg
    One of the ideas of Python's design philosophy is "There should be one ... obvious way to do it." (PEP 20), but that can't always be true. I'm specifically referring to (simple) if statements versus boolean evaluation. Consider the following: if words: self.words = words else: self.words = {} versus self.words = words or {} With such a simple situation, which is preferable, stylistically speaking? With more complicated situations one would choose the if statement for readability, right?

  • Characters spilled over multiple columns in Oracle 11g?

    - by vicky21
    This is related to question: How to store unlimited characters in Oracle 11g? If maximum I need is 8000 characters, can I just add 3 more varchar2 columns so that I will have 4 columns with 2000 char each to get 8000 chars. So when the first column is full, values would be spilled over to the next column and so on. Will this design have any bad side effects? Please suggest.

  • What are common uses of condition variables in C++?

    - by jasonline
    I'm trying to learn about condition variables. I would like to know what are the common situations where condition variables are used. One example is in a blocking queue, where two threads access the queue - the producer thread pushes an item into the queue, while the consumer thread pops an item from the queue. If the queue is empty, the consumer thread is waiting until a signal is sent by the producer thread. What are other design situations where you need a condition variable to be used?

  • Efficient retrieval of lists over WebServices

    - by Chris
    I have a WCF WebService that uses LINQ and EF to connect to an SQL database. I have an ASP.NET MVC front end that collects its data from the webservice. It currently has functions such as List<Customer> GetCustomers(); As the number of customers increases massively the amount of data being passed increases also reducing efficiency. What is the best way to "page data" across WebServices etc. My current idea is to implement a crude paging system such as List<Customer> GetCustomers(int start, int length); This, however, means I would have to replicate such code for all functions returning List types. It is unfortunate that I cannot use LINQ as it would be much nicer. Does anyone have any advice or ideas of patterns to implement that would be "as nice as possible" Thanks
