Minimum to install for a visual web browser in Ubuntu Server

I have set up a machine with Ubuntu Server. Some of the server software I want to run on it has web based user interfaces for setting it up et cetera. I know I could connect to it from a different machine which has a graphical user interface, but in this case I would rather do it on the box. So, from a fresh Ubuntu Server installation, what is the minimum I need to install to be able to launch a web browser I can use for this? For example chromium, firefox or arora.

Comparing the Performance of Visual Studio's Web Reference to a Custom Class

As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using <a href="http://www.4guysfromrolla.com/articles/120705-1.aspx">ASP.NET's Membership system</a> is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a <a href="http://www.4guysfromrolla.com/articles/100803-1.aspx">web service</a> generates markup that auto-creates a <i>proxy class</i>, which handles the low-level details of invoking the web service, serializing parameters,

High level overview of Visual Studio Extensibility APIs

- by Daniel Cazzulino

If your head is dizzy with the myriad VS services and APIs, from EnvDTE to Shell.Interop, this should clarify a couple things. First a bit of background: APIs on EnvDTE (DTE for short, since that’s the entry point service you request from the environment) was originally an API intended to be used by macros. It’s also called the automation API. Most of the time, this is a simplified API that is easier to work with, but which doesn’t expose 100% of what VS is capable of doing. It’s also kind of the “rookie” way of doing VS extensibility (VSX for short), since most hardcore VSX devs sooner or later realize that they need to make the leap to the “serious” APIs. The “real” VSX APIs virtually always start with IVs, make heavy use of uint, ref/out parameters and HResults. These are the APIs that have been evolving for years and years, and there is a lot of COM baggage. ...Read full article

Multiple Document Interfaces in Visual Basic

What is Multiple Document Interface (MDI)? In most VB.NET applications, it is using a single document interface (SDI). In this type of interface, every window is unique to aother window. But in multiple document interface, it works by having one parent window with child windows under it. See the screenshot below: As you can see, there is one parent window (in gray color) and there are 3 child windows (in blue, violet and orange color). You can have more than 3 child windows depending on your application requirements. But you can only have one parent window. Depending on the design of your MDI...

Rotating a NetBeans Visual Library Widget

- by Geertjan

Trying to create a widget which, when clicked, rotates slightly further on each subsequent click: Above, the bird where the mouse is visible has been clicked a few times and so has rotated a bit further on each click. The code isn't quite right yet and I'm hoping someone will take this code, try it out, and help with a nice solution! public class BirdScene extends Scene { public BirdScene() { addChild(new LayerWidget(this)); getActions().addAction(ActionFactory.createAcceptAction(new AcceptProvider() { public ConnectorState isAcceptable(Widget widget, Point point, Transferable transferable) { Image dragImage = getImageFromTransferable(transferable); if (dragImage != null) { JComponent view = getView(); Graphics2D g2 = (Graphics2D) view.getGraphics(); Rectangle visRect = view.getVisibleRect(); view.paintImmediately(visRect.x, visRect.y, visRect.width, visRect.height); g2.drawImage(dragImage, AffineTransform.getTranslateInstance(point.getLocation().getX(), point.getLocation().getY()), null); return ConnectorState.ACCEPT; } else { return ConnectorState.REJECT; } } public void accept(Widget widget, final Point point, Transferable transferable) { addChild(new BirdWidget(getScene(), getImageFromTransferable(transferable), point)); } })); } private Image getImageFromTransferable(Transferable transferable) { Object o = null; try { o = transferable.getTransferData(DataFlavor.imageFlavor); } catch (IOException ex) { } catch (UnsupportedFlavorException ex) { } return o instanceof Image ? (Image) o : null; } private class BirdWidget extends IconNodeWidget { private int theta = 0; public BirdWidget(Scene scene, Image imageFromTransferable, Point point) { super(scene); setImage(imageFromTransferable); setPreferredLocation(point); setCheckClipping(true); getActions().addAction(ActionFactory.createMoveAction()); getActions().addAction(ActionFactory.createSelectAction(new SelectProvider() { public boolean isAimingAllowed(Widget widget, Point localLocation, boolean invertSelection) { return true; } public boolean isSelectionAllowed(Widget widget, Point localLocation, boolean invertSelection) { return true; } public void select(final Widget widget, Point localLocation, boolean invertSelection) { theta = (theta + 100) % 360; repaint(); getScene().validate(); } })); } @Override public void paintWidget() { final Image image = getImageWidget().getImage(); Graphics2D g = getGraphics(); g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); Rectangle bounds = getClientArea(); AffineTransform newXform = g.getTransform(); int xRot = image.getWidth(null) / 2; int yRot = image.getWidth(null) / 2; newXform.rotate(theta * Math.PI / 180, xRot, yRot); g.setTransform(newXform); g.drawImage(image, bounds.x, bounds.y, null); } } } The problem relates to refreshing the scene after the rotation. But it would help if someone would just take the code above, add it to their own application, try it out, see the problem for yourself, and develop it a bit further!

Paypal Payflow pro library

- by John Stewart

I already have an express checkout integrated with my Codeigniter application. Now I want to integrate seamless paypal where I collect the CC information and pass it to Paypal (via backend) and once everything is approved, my application shows that to the user. All this with out ever going to Paypal's website. I know that Paypal gives a bunch of sample code but they have so many different products that advertise to do the same thing. Is there any wrapper library in PHP that I can use for handling all this? What sort of design decision is involved in migrating to such system? Would I need SSL certificates for this?

Generation of .tlb Files in Windows 7 Pro 32-bit

- by aF

I have a C++ DLL that imports a .tlb file generated in a C# project. The C++ DLL is a wrapper DLL containing functions that call the corresponding C# functions. When I call the C++ functions on the computer that I built the projects, all works well. But when I copy the DLL's and generated tlb's to another computer with the same exact version of Windows and installed programs andI call the C++ functions, it breaks with a COM error. However, after recompiling the projects on the new computer, everything works again. I already checked the "Work on All Computers" for both projects but this keeps happening. What else do I need to do for the DLL's to work on all computers?

Creating Visual Studio Extension Files (VSIX) for Template Deployment

While working on some plugins for the new Seesmic Desktop PlatformI got sick of copying and pasting some boiler plate code over and over. I had created some helper templates for myself so that I could say FileNew Seesmic Desktop Plugin and get everything I needed initially. This weekend I had some time and formalized those templates into an easy-to-use installer for anyone to consume. NOTE: It is likely that Seesmic themselves will create developer project/item templatesthese were for my own...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

Pro/con: Initializing a variable in a conditional statement

- by steffenj

In C++ you can initialize a variable in an if statement, like so: if (CThing* pThing = GetThing()) { } Why would one consider this bad or good style? What are the benefits and disadvantages? Personally i like this style because it limits the scope of the pThing variable, so it can never be used accidentally when it is NULL. However, i don't like that you can't do this: if (CThing* pThing = GetThing() && pThing->IsReallySomeThing()) { } If there's a way to make the above work, please post. But if that's just not possible, i'd still like to know why. Question borrowed from here, similar topic but PHP.

TabRenderer with no visual styles enabled?

- by DxCK

I want to draw a custom TabControl with custom functionality. To do this, i inherited the Panel class and overrided OnPaint method to draw with TabRenderer class. The problem is that TabRenderer working only when visual styles enabled (can be checked with TabRenderer.IsSupported), but what should i do if visual styles disabled? In this case, I thought using the ControlPaint class to draw tabs without visual styles, but it has no draw method related to Tabs. I want it basically to behave visually like the regular TabControl.

Channel 9 Interview: Array and Collection Initializers in Visual Basic 2010 (Beth Massi, Spotty Bowl

Ive written about collection initializers on my blog before, but I thought Id catch up with the VB Team to tell me more about how they really work. In this interview Spotty Bowles, a tester on the VB Compiler team, shows us a couple of new language features: Array and Collection Initializers. He gives us insight into how they are implemented in the compiler and best practices on how to use them in our code. Additionally, he discusses how to extend Collection Initializers with your own extension...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

installing Delphi5 pro in windows 64b

- by Larry

Please dont laugh . Over the past 15 years or so I've written all the software that runs my medical practice in D5. Last week when I went to DelphiArea to update a component I got attacked and my disk became unbootable/unrecoverable. I have my original D5p disk and all the components backed up but I want to migrate to W7. I don't care if my delphi apps look like vista/7, I just want to be able to install it and code on the machine again for maintenance purposes. 1) are there any tricks to install D5 so it works in W7? 2) is using a vm program really the only/best way? if so, which is suggested. Thanks in advance. My new Gateway zx6800-03 arrives tomorrow! Larry [email protected]
