  • Using Fzip lib under Adobe Air App

    - by Rafael Oliveira
    I'm currently working on a project for Adobe Air (1.5.3) and I need to unzip a file, copy some of its contents to another file. Then I saw people talking about the Fzip (http://codeazur.com.br/lab/fzip) lib. The problem is that I don't know how to "import" or use this library with Javascript and Adobe Air, since Javascript doesn't have the import directive. How can I manage to do that ?

Those are zlib functions. It seems like it is loading the zlib.h ok, but the symbols aren't being linked in? Just to make sure I downloaded the latest zlib and did a make install, no help. I have no clue what's going on here, it seems like it should be pretty basic, that library is nothing special. Help would be appreciated. Thanks.

  • Redirect away from HTTPS with ASP.NET MVC App

    - by Amadiere
    I'm using ASP.NET MVC 2 and have a login page that is secured via HTTPS. To ensure that the user always accesses those pages via SSL, I've added the attribute [RequiresHttps] to the controller. This does the job perfectly. When they have successfully logged in, I'd like to redirect them back to HTTP version. However, there isn't a [RequiresHttp] attribute and I'm struggling to get my head around how I might achieve this. The added (potential) complication is that the website when in production is hosted at the route of the domain, but for development and testing purposes it is within a sub directory / virtual directory / application. Am I over-thinking this and is there an easy solution staring me in the face? Or is it a little more complex?

  • Architecting ASP.net MVC App to use repositories and services

    - by zaladane
    Hello, I recently started reading about ASP.net MVC and after getting excited about the concept, i started to migrate all my webform project to MVC but i am having a hard time keeping my controller skinny even after following all the good advices out there (or maybe i just don't get it ... ). The website i deal with has Articles, Videos, Quotes ... and each of these entities have categories, comments, images that can be associated with it. I am using Linq to sql for database operations and for each of these Entities, i have a Repository, and for each repository, i create a service to be used in the controller. so i have - ArticleRepository ArticleCategoryRepository ArticleCommentRepository and the corresponding service ArticleService ArticleCategoryService ... you see the picture. The problem i have is that i have one controller for article,category and comment because i thought that having ArticleController handle all of that might make sense, but now i have to pass all of the services needed to the Controller constructor. So i would like to know what it is that i am doing wrong. Are my services not designed properly? should i create Bigger service to encapsulate smaller services and use them in my controller? or should i have an articleCategory Controller and an articleComment Controller? A page viewed by the user is made of all of that, thee article to be viewed,the comments associated with it, a listing of the categories to witch it applies ... how can i efficiently break down the controller to keep it "skinny" and solve my headache? Thank you! I hope my question is not too long to be read ...

  • How to use SendMessage to another form in same app

    - by Robert Frank
    I've been trying to get this to work for some time now and can't figure it out. Probably obvious once you know it. I simply want a non-modal form (or perhaps an instantiated non-TForm class) to send a message to the application's main form. I can make the main form send a message to itself and receive (announcing with a beep) But, I can't seem to have other objects send messages to the main form. I'm using WM_MY_MESSAGE = WM_APP + 200; What should the first argument of the SendMessage be to send a message to the main form? Even sending it to Application.MainForm.Handle doesn't seem to work. The reason I need to do this is that the modal form has a slider that another form (#2) needs to know when it changes. Notifying the other form via a callback procedure was making it sluggish as form #2 did some work before returning from the call. Is having a modal form send a windows message to the main form a reasonable way to avoid this?

  • Looking for best practise for writing a serial device communication app

    - by cdotlister
    I am pretty new to serial comms, but would like advise on how to best achieve a robust application which speak to and listens to a serial device. I have managed to make use of System.IO.SerialPort, and successfully connected to, sent data to and recieved from my device. The way things work is this. My application connects to the Com Port and opens the port.... I then connect my device to the com port, and it detects a connection to the PC, so sends a bit of text. it's really just copyright info, as well as the version of the firmware. I don't do anything with that, except display it in my 'activity' window. The device then waits. I can then query information, but sending a command such as 'QUERY PARAMETER1'. It then replies with something like: 'QUERY PARAMETER1\r\n\r\n76767\r\n\r\n' I then process that. I can then update it by sending 'SET PARAMETER1 12345', and it will reply with 'QUERY PARAMETER1\r\n\r\n12345\r\n\r\n'. All pretty basic. So, what I have done is created a Communication Class. this call is called in it's own thread, and sends data back to the main form... and also allows me to send messages to it. Sending data is easy. Recieving is a bit more tricky. I have employed the use of the datarecieved event, and when ever data comes in, I echo that to my screen. My problem is this: When I send a command, I feel I am being very dodgy in my handling. What I am doing is, lets say I am sending 'QUERY PARAMETER1'. I send the command to the device, I then put 'PARAMETER1' into a global variable, and I do a Thread.Sleep(100). On the data received, I then have a bit of logic that checks the incoming data, and sees if the string CONTAINS the value in the global variable. As the reply may be 'QUERY PARAMETER1\r\n\r\n76767\r\n\r\n', it sees that it contains my parameter, parses the string, and returns the value I am looking for, but placing it into another global variable. My sending method was sleeping for 100ms. It then wakes, and checks the returned global variable. If it has data... then I'm happy, and I process the data. Problem is... if the sleep is too short.. it will fail. And I feel it's flaky.. putting stuff into variables.. then waiting... The other option is to use ReadLine instead, but that's very blocking. So I remove the data received method, and instead... just send the data... then call ReadLine(). That may give me better results. There's no time, except when we connect initially, that data comes from the device, without me requesting it. So, maybe ReadLine will be simpler and safer? Is this known as 'Blocking' reads? Also, can I set a timeout? Hopefully someone can guide me.

  • SSL connection using Java standalone app

    - by Marquinio
    I have created a standalone executable JAR program that needs to send private information over a SSL connection. I was not able to establish the SSL connection using certificates. Was getting this: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path `building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target` So I found some code somewhere that creates a trust manager that does not validate certificate chains: // Create a trust manager that does not validate certificate chains TrustManager[] trustAllCerts = new TrustManager[]{ new X509TrustManager() { public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; } public void checkClientTrusted( java.security.cert.X509Certificate[] certs, String authType) { } public void checkServerTrusted( java.security.cert.X509Certificate[] certs, String authType) { } } }; That did the trick and I was able to establish SSL connection without any certificates. My concern is if the data will still be encrypted when exchanging private information. This is an execute JAR file that clients will be downloading to their computers. So is a certificate really necessary for this case? Thanks.

  • Releasing an app - Developed on one account, releasing/approving on another

    - by stumac85
    Hi there, We have developed an application for a company who want to release it under their own account. It has been developed on our account and has had provisioning profiles attached to it from our own account. What is the best way to do this? Do I have to send them the xCode project and talk them through how to attack a provisioning profile to the project? Or can I just get their login details and create a provisioning profile from the Mac in the office and do it for them? Or is there a "transfer to different account" option? Many thanks!

  • Images not displayed in silverlight when app is run

    - by Sean
    I'm trying to display an image within a Silverlight application but the image does not display when the application is run. When creating the project within Visual Studio I chose the "Automatically generate a test page to host Silverlight at build time" option. Complete code as an example: <UserControl x:Class="SilverlightApplication3.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"> <StackPanel> <Image Source="http://www.beachtownpress.com/db5/00415/beachtownpress.com/_uimages/beach7.jpg" /> </StackPanel> </UserControl> The application appears perfectly within Visual Studio, but when I run the application, the image does not display. Any ideas?

    - by vbNewbie
    I have an application that accesses a sql server 2008 database. The server and database is stored on my local harddrive and I would like to learn to scale this up to having multiple users in our office access the application which I will i deploy on a server. For now the database will stay on my pc until I am ready to put it on a dedicated server for myself but for now how do I allow the application still to access my database. Here is my current connection string: <add key="ConnectionString" value="Data Source=.;Initial Catalog=SearchEngine;User ID=sa;Password=pss;Trusted_Connection=False;" /> Now I know how to deploy a general vb.net application but what I dont know is what to do with the database.

  • Send Logcat output of an App to an EmailAdress

    - by Sebi
    Hi Were now testing our application with a few friends. Sometimes there are some errors which dont throw an exception. So I don't really know whats the problem was. So i thought it would be a good idea to implement a menu item which allows to send the logcat file to a email adress, so that we can examine the logcat. Unfortunately I didnt found a hint in the Internet how to extract the Logcat from a phone. How to send a email shouldn't be the problem.

  • C#, WindowsForms difference to simple Console App

    - by daemonfire300
    Hi there, I currently started to "port" my console projects to WinForms, but it seems I am badly failing doing that. I am simply used to a console structure: I got my classes interacting with each other depending on the input coming from the console. A simple flow: Input -> ProcessInput -> Execute -> Output -> wait for input Now I got this big Form1.cs (etc.) and the "Application.Run(Form1);" But I really got no clue how my classes can interact with the form and create a flow like I described above. I mean, I just have these "...._Click(object sender....)" for each "item" inside the form. Now I do not know where to place / start my flow / loop, and how my classes can interact with the form. thanks and regards daemonfire

  • Pros and Cons on where to place business logic: app level or DB

    - by Juri
    Hi, I always again encounter discussions about where to place the business logic: inside a business layer in the application code or down in the DB in terms of stored procedures. Personally I'd tend to the 1st approach, but I'd like to hear some opinions from your part first, without influencing you with my personal views. I know there doesn't exist a one-size-fits-all solution and it often depends on many factors, but we can discuss about that. Btw, we are in the context of web applications and our current approach is to have UI layer which accepts UI input and does a first, client-side validation Business layer with a number of service-classes which contains the business logic including validation for user input (server-side) Data Access Layer which calls stored procedures from the DB for doing persistency/read operations Many people however tend to move the business layer stuff (especially regarding the validation) down to the DB in terms of stored procedures. What do you think about it? I'd like to discuss.

  • How to increase Java heap space for a tomcat app

    - by Ankur
    There are lots of questions that ask this or a similar question. They all give the command that has to be executed, what I don't understand is where do I write this command. I want to permanently increase the heap space for my tomcat apps. I read this page http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html and it says under the Tomcat section Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example, set CATALINA_OPTS=-Xms512m -Xmx512m (Windows, no "" around the value) export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash, "" around the value) setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh, "" around the value) So I replaced the line set CATALINA_OPTS= with set CATALINA_OPTS=-Xms512m -Xmx512m But I still get the error.

  • Building Android app from ant via Hudson - chicken and egg problem

    - by Eno
    When using an Android-generated ant build file, the file references your SDK installation via an sdk.dir property inside the local.properties files which is generated by "android update project -p .". The comments in build.xml suggest that local.properties should NOT be checked into version control. BUT, when you run your build from Hudson, it does a fresh checkout of your code from version control, hence local.properties does not exist and subsequently the build fails without sdk.dir being set. So its kind of chicken and egg problem. As a workaround I have checked local.properties into version control for now (nobody else will use it) but I was curious as to how other developers had tackled this problem ?
