• Calling Web Service with Complex Parameters in ADF Mobile

  - by Shay Shmeltzer

  Many of the SOAP based web services out there have parameters of specific object types - so not just simple String/int inputs. The ADF Web service data control makes it quite simple to interact with them. And this applies also in the case of ADF Mobile. Since there were several thread on OTN asking about this - I thought I'll do a quick demo to refresh people memory about how you pass these "complex" parameters to your Web service methods. By the way - this video is also relevant if you are not doing mobile development, you'll basically use the exact same process for building "regular web" ADF applications that access these types of Web services. One more thing you might want to do after you create the page is look at the binding tab to see the method call in there, and notice the parameters for it in the structure property. Go and look at their NDValue property to get the complete picture.

• Workflow: Operate Zones

  - by Owen Allen

  The Operate Zones workflow is another of the workflow documents that we introduced recently. It follows naturally after the Deploy Oracle Solaris 11 Zones workflow that I talked about last week, so I thought I'd talk about it next. This workflow is less linear than the zone deployment workflow. It's built around this image: The left side shows you the prerequisites for zone operation: you have to deploy libraries and deploy either Oracle Solaris 10 or 11 zones - whichever type you want to manage using this workflow. Once you have the zones deployed, you can begin to operate them. If you want to associate resources with the global zone, the workflow directs you to the Exploring Your Server Pools how-to, which talks about adding global zones to server pools and associating libraries and network resources with them. Otherwise, it directs you to a set of how-tos about zone management: Managing the Configuration of a Zone, which explains how to add storage, edit zone attributes, and connect zones to networks; Lifecycle Management of Zones, which explains how to halt, shut down, boot, reboot, or delete a zone; and Migrating Zones, which explains how to move a zone to a new global zone in the same server pool. Finally, it directs you to the Update Oracle Solaris workflow when you want to update your zones, and to the Monitor and Manage Incidents workflow to learn more about monitoring your assets.

• Should you salary reflect how much work there is for you or does that not matter? [closed]

  - by Kevin Simper

  I am working in a consulting company, where the company mostly do IT support. The website is also only focused on IT support, and we do not therefore capture leads for the Web Department. We aim for Small busniess, which needs new computers and firewalls. We were having a performance conversation and talked about salary and my employer told that he was not impressed by the revenue I was generating. I told that I did not have enough work and I would like to get more tasks and project so that i could reach the goal, but that i did not think it was my fault that there was not enough work. He said that it was not his fault either, but he could not pay me more. Is he right that I should not get paid more just because my employee can not get enough Web projects, or should i be paid what i am worth not based on the work amount the sales generate?

• How to test a localized WPF application in visual studio 2012

  - by Michel Keijzers

  I am trying to create a localized application in C# / WPF in Visual Studio 2012. For that I created two resource files and changed one string in a (XAML) window to use the resource files (instead of a hardcoded string). I see the English text from the resource file, which is correct. However, I want to check if the other resource file (fr-FR) also works but I cannot find a setting or procedure how to change my 'project' to run in French. Thanks in advance.

• Has any hobbyist attempted to make a simple VGA-graphics based operating system in machine code?

  - by Bigyellow Bastion

  I mean real bare bones, bare machine here(no Linux kernel, pre-existing kernel, or any bootloader). I mean honestly write the bootloading software in direct microarchitecture-specific machine opcode, host the operating system, interrupts, I/O, services, and graphical software and all hardware interaction, computation, and design entirely in binary. I know this is quite the leap here, but I was thinking to practice first in x86 assembly (not binary) 16-bit style. Any ideas?

• Single API Architecture

  - by user1901686

  When people refer to an architecture that involves a single service API that all clients talk to (a client can be an iPad app, etc), what is the "client" for the web app -- is it A) the web browser itself. Thus, the entire app is written in html/css/javascript and ajax calls to the service are made to fetch data and changes are made through javascript or B) you have an MVC-like stack on a server, only instead of the controllers calling to the model layer directly, they call to the service API which return models that are used to render the traditional views or C) something else?

• How should I safely send bulk mail? [closed]

  - by Jerry Dodge

  First of all, we have a large software system we've developed and have a number of clients using it in their own environment. Each of them is responsible for using their own equipment and resources, we don't provide any services to share with them. We have introduced an automated email system which sends emails automatically via SMTP. Usually, it only sends around 10-20 emails a day, but it's very possible to send bulk email up to thousands of people in a single day. This of course requires a big haul of work, which isn't necessarily the problem. The issue arises when it comes to the SMTP server we're using. An email server is issued a number of relays a day, which is paid for. This isn't really necessarily the issue either. The risk is getting the email server blacklisted. It's inevitable, and we need to carefully take all this into consideration. As far as I can see, the ideal setup would be to have at least 50 IP addresses on multiple servers, each of which hosts its own SMTP server. When sending bulk email, it will divide them up across these servers, and each one will process its own queue. If one of those IP's gets blacklisted, it will be decommissioned and a new IP will replace it. Is there a better way that doesn't require us to invest in a large handful of servers? Perhaps a third party service which is meant exactly for this?

• Best Design Pattern for Coupling User Interface Components and Data Structures

  - by szahn

  I have a windows desktop application with a tree view. Due to lack of a sound data-binding solution for a tree view, I've implemented my own layer of abstraction on it to bind nodes to my own data structure. The requirements are as follows: Populate a tree view with nodes that resemble fields in a data structure. When a node is clicked, display the appropriate control to modify the value of that property in the instance of the data structure. The tree view is populated with instances of custom TreeNode classes that inherit from TreeNode. The responsibility of each custom TreeNode class is to (1) format the node text to represent the name and value of the associated field in my data structure, (2) return the control used to modify the property value, (3) get the value of the field in the control (3) set the field's value from the control. My custom TreeNode implementation has a property called "Control" which retrieves the proper custom control in the form of the base control. The control instance is stored in the custom node and instantiated upon first retrieval. So each, custom node has an associated custom control which extends a base abstract control class. Example TreeNode implementation: //The Tree Node Base Class public abstract class TreeViewNodeBase : TreeNode { public abstract CustomControlBase Control { get; } public TreeViewNodeBase(ExtractionField field) { UpdateControl(field); } public virtual void UpdateControl(ExtractionField field) { Control.UpdateControl(field); UpdateCaption(FormatValueForCaption()); } public virtual void SaveChanges(ExtractionField field) { Control.SaveChanges(field); UpdateCaption(FormatValueForCaption()); } public virtual string FormatValueForCaption() { return Control.FormatValueForCaption(); } public virtual void UpdateCaption(string newValue) { this.Text = Caption; this.LongText = newValue; } } //The tree node implementation class public class ExtractionTypeNode : TreeViewNodeBase { private CustomDropDownControl control; public override CustomControlBase Control { get { if (control == null) { control = new CustomDropDownControl(); control.label1.Text = Caption; control.comboBox1.Items.Clear(); control.comboBox1.Items.AddRange( Enum.GetNames( typeof(ExtractionField.ExtractionType))); } return control; } } public ExtractionTypeNode(ExtractionField field) : base(field) { } } //The custom control base class public abstract class CustomControlBase : UserControl { public abstract void UpdateControl(ExtractionField field); public abstract void SaveChanges(ExtractionField field); public abstract string FormatValueForCaption(); } //The custom control generic implementation (view) public partial class CustomDropDownControl : CustomControlBase { public CustomDropDownControl() { InitializeComponent(); } public override void UpdateControl(ExtractionField field) { //Nothing to do here } public override void SaveChanges(ExtractionField field) { //Nothing to do here } public override string FormatValueForCaption() { //Nothing to do here return string.Empty; } } //The custom control specific implementation public class FieldExtractionTypeControl : CustomDropDownControl { public override void UpdateControl(ExtractionField field) { comboBox1.SelectedIndex = comboBox1.FindStringExact(field.Extraction.ToString()); } public override void SaveChanges(ExtractionField field) { field.Extraction = (ExtractionField.ExtractionType) Enum.Parse(typeof(ExtractionField.ExtractionType), comboBox1.SelectedItem.ToString()); } public override string FormatValueForCaption() { return string.Empty; } The problem is that I have "generic" controls which inherit from CustomControlBase. These are just "views" with no logic. Then I have specific controls that inherit from the generic controls. I don't have any functions or business logic in the generic controls because the specific controls should govern how data is associated with the data structure. What is the best design pattern for this?

• Is there a way to check if redistributed code has been altered?

  - by onlineapplab.com

  I would like to redistribute my app (PHP) in a way that the user gets the front end (presentation) layer which is using the API on my server through a web service. I want the user to be able to alter his part of the app but at the same time exclude such altered app from the normal support and offer support on pay by the hour basis. Is there a way to check if the source code was altered? Only solution I can think of would be to get check sums of all the files then send it through my API and compare them with the original app. Is there any more secure way to do it so it would be harder for the user to break such protection?

• Interface extension

  - by user877329

  Suppose that I have an input stream interface, which defines a method for reading data. I also have a seekable interface which defines a method for seeking. A natural way of defining a input file is then to implement both input stream and seekable. I want to construct a data decoder from the input stream interface so I can read data from a file or from another stream. The problem is that I also want to implement seek functionality to the data decoder, since I want to be able to step individual records not raw bytes. This is not possible if I only provide an input stream, which does not have the bytewise seek method. Should I skip the seekable interface and add the seek method to input stream instead and force all streams to at least leave it as a nop.

• Remembering user credentials in standalone Application

  - by srk

  I'm developing a standalone application using java, I have a Login screen, wherein user enters his username and password. For each instance of the application, user have to enter his credentials. From a usability standpoint, I thought of keeping a remember me check Button. My question is, as I am not using any database, how do I persist the user details. I have some rough thoughts, storing them in a property file and retrieving. I think there may be better approaches than the one I had. Any Ideas and suggestions?

• How do you update live web sites with code changes?

  - by Aaron Anodide

  I know this is a very basic question. If someone could humor me and tell me how they would handle this, I'd be greatful. I decided to post this because I am about to install SynchToy to remedy the issue below, and I feel a bit unprofessional using a "Toy" but I can't think of a better way. Many times I find when I am in this situation, I am missing some painfully obvious way to do things - this comes from being the only developer in the company. ASP.NET web application developed on my computer at work Solution has 2 projects: Website (files) WebsiteLib (C#/dll) Using a Git repository Deployed on a GoGrid 2008R2 web server Deployment: Make code changes. Push to Git. Remote desktop to server. Pull from Git. Overwrite the live files by dragging/dropping with windows explorer. In Step 5 I delete all the files from the website root.. this can't be a good thing to do. That's why I am about to install SynchToy... UPDATE: THANKS for all the useful responses. I can't pick which one to mark answer - between using a web deployment - it looks like I have several useful suggesitons: Web Project = whole site packaged into a single DLL - downside for me I can't push simple updates - being a lone developer in a company of 50, this remains something that is simpler at times. Pulling straight from SCM into web root of site - i originally didn't do this out of fear that my SCM hidden directory might end up being exposed, but the answers here helped me get over that (although i still don't like having one more thing to worry about forgetting to make sure is still true over time) Using a web farm, and systematically deploying to nodes - this is the ideal solution for zero downtime, which is actually something I care about since the site is essentially a real time revenue source for my company - i might have a hard time convincing them to double the cost of the servers though. -- finally, the re-enforcement of the basic principal that there needs to be a single click deployment for the site OR ELSE THERE SOMETHING WRONG is probably the most useful thing I got out of the answers. UPDATE 2: I thought I come back to this and update with the actual solution that's been in place for many months now and is working perfectly (for my single web server solution). The process I use is: Make code changes Push to Git Remote desktop to server Pull from Git Run the following batch script: cd C:\Users\Administrator %systemroot%\system32\inetsrv\appcmd.exe stop site "/site.name:Default Web Site" robocopy Documents\code\da\1\work\Tree\LendingTreeWebSite1 c:\inetpub\wwwroot /E /XF connectionsconfig Web.config %systemroot%\system32\inetsrv\appcmd.exe start site "/site.name:Default Web Site" As you can see this brings the site down, uses robocopy to intelligently copy the files that have changed then brings the site back up. It typically runs in less than 2 seconds. Since peak traffic on this site is about 2 requests per second, missing 4 requests per site update is acceptable. Sine I've gotten more proficient with Git I've found that the first four steps above being a "manual process" is also acceptable, although I'm sure I could roll the whole thing into a single click if I wanted to. The documentation for AppCmd.exe is here. The documentation for Robocopy is here.

• Citrix SDK: Where to start? [closed]

  - by Bob Dole

  I'm needing to start hacking around the Citrix SDK and am trying to figure out where to start. I'm wanting to basically find a way to pass data from the client to the server and figure out how to open an application on the citrix client. I see there is a XenApp SDK, and Virtual Channel SDK but really don't know which one I need to start with. I have a Citrix development virtual server set up, but am unsure how to get started. Does someone know of a good site/tutorial on how to get started with the various Citrix API's quickly?

• Define outgoing ip address when using ssh

  - by Mark

  I have an ubuntu server machine (12.04) with 4 IP addresses for different websites that require unique ssl certificates. I sometimes ssh out from this box and the box I am going to I have to tell it what IP address I will be coming from. How do I specify which of the 4 ip addresses I want to use as my outgoing IP address? If i do an ifconfig it appears that I am going out as the last ipaddress. I guess you would want to specify either the address or the interface.... Thanks in advance! -Mark

• I cannot change the screen brightness

  - by user1793249

  here's my problem: Ever since I installed Ubuntu 12.10 on my computer I haven't been able to change the screen brightness, it was always set to the maximum. I did take a look at this post: Decrease Backlight Below Minimum And it helped me resolved the issue with the unbearable brightness, however one problem persists: I cannot change it through "Brightness & Lock" or the function buttons (F2 and F3), when I press the buttons, the animation shows up but nothing happens. I tried the following: http://www.refreshit.info/2012/08/solved-brightness-increase-and-decrease.html It did nothing... If it helps: I have an HP-dv6 6185la, it has an ATI Radeon 6770M HD card and an Intel HD Integrated Graphics Card It only detects the "Intel® Sandybridge Mobile" Thanks in advance.

• Very frequent system problems since 12.10 upgrade

  - by Jazz

  Since I recently upgrade my 12.04 install to 12.10, there is loads more instability generally. I have captured just the latest example - often occurring just after startup and login. Other random times, similar things happen - not always the same executable is reported - might be many different problems. Is everyone finding 12.10 a bit unstable (in which case I can hope for fixes to filter through over the coming months)?

• Change from tri-boot to dual-boot

  - by Andrew Robinson

  I have been tri-booting Windows 7, Windows 8 Release Candidate and Ubuntu 12.04 LTS for a few months now. I have decided that, since I have no touch screen, I will not purchase Win 8. I now want to get rid of the Win 8 RC, then add that partition space to my Ubuntu partition, but have no idea how to accomplish this. Do I need to uninstall Win 8 RC from within Windows first? The grub loader sends me to the Win 8 loader, where I have Win 7 as the default. Does that complicate things? Any assistance anyone can give would be greatly appreciated.

• Installing Ubuntu Desktop on usb stick

  - by Tobias Gårdner

  trying to install Ubuntu Desktop on a USB stick but I do not succeed. First time I tried, the USB stick contained an installation of USB server and I wanted to start over again. However, it complained about partioning. Removed all the partitions from the stick and tried again, hoping that the installer would help me out with partioning... But now the USB stick did not show up at all... Created one partion NTFS on the USB stick and tried again but the only "automated" alternative I get for installing is to overwrite or add Ubuntu to my HDD which already contains Windows, something that I do not want... Do I need to manually create partions on the stick in the installer? Which partitions should I create? The USB stick is 8GB and the machine that I will test it on has 8GB memory. Helpful for any support here. Regards, Tobbe G
