  • Which Qt4 Widgets whould I be using? [closed]

    - by Topo
    I'm using Qt 4 to design an IDE but I'm having a hard time with the GUI design. On the left side I want to put a widget that shows the files on the current project and on the left side a similar one but with the classes, methods, etc... Which widget should I use the Tree view or the tree widget? Also, I want to have a tab widget in the center with a text edit and this items the tree widgets and the tab widget to move and resize according to the window size. How can I accomplish this?

  • Is Java a good choice for small to medium size websites? [closed]

    - by mephisto
    Why do I ask? I want to use one language not two. Yes I know with Java and .NET I can program anything, but, as a website it should have a good design, I don't want to build ugly sites. Which is why for smaller sites I use PHP, I can get the e-comm I want and also a nice UI pretty easily, unlike in ASP.NET. But would I run into this design rstriction with Java (I've never used it). Plus, Java would also give me exposure to Android development. So..then I could ditch PHP? I guess I am looking for the 'one ring to rule them all', and not 2 or 3 (languages). Thanks in advance,

  • A first look at Haiku (alpha)

    <b>Distrowatch:</b> "When talking about kernel scheduling and desktop responsiveness, it's common to hear people in the tech community talk fondly of BeOS, a desktop system which hails from the 1990s. BeOS had a well-deserved reputation for providing users with a polished desktop and smooth interaction, even when the processor was under heavy load."

  • Installing a WordPress Theme Yourself

    Having a WordPress theme for your blog can be a really good decision because an apt theme conveys two things: 1- You care a lot about the presentation of your blog. 2- You want the visitor or reader of your blog to derive the maximum utility or value from your blog through interaction and good user-experience. Here is how you can install a WordPress theme.

  • Using PDO for Data Management

    - by edorahg
    This question is more a design oriented question than a code specific question. I am new to PHP and I am planning to use PDO as a data access layer. Say for instance I have a class called CITY. Now if I need to create an instance of this class, what is the best technique. Should have a singleton DB access class which is used to write and read data from the db layer. OR should I delegate it to the individual class object. For example if I invoke city.save() (city is a class), then the city class will handle the saving of that city object's data into the database. Excuse my ignorance but i have a java background and therefore trying to understand what is the best design principle for data management when using php.

  • How to get MMF2 or similar program

    - by Feldpausch All4
    I took a Game Design class a while ago that used Multimedia Fusion 2. Now I would like to get it on my computer, but I don't have the disk anymore. I have access to the program on my Dad's computer, but I want to get it on mine. Is there a way to get MMF2 for free on my computer? If not, are there any other free game design programs like MMF2 (knowing code is not necessary)? Edit: If I paid the $50 to upgrade to 2.5, could I put it on a second computer, or is that not possible?

  • Logic behind SCCM 2012 required PXE deployments

    - by Omnomnomnom
    I'm in the process of setting up Windows 7 deployment through PXE boot, with Microsoft SCCM 2012. The imaging itself works very well, but I have a question about the logic behind PXE deployments. My setup is the following: My Windows 7 deployment task sequence is deployed to the unknown computers group. (not required, press F12 to start installing) OSDComputerName variable is also set on the unknown computers group, so unknown computers that are being imaged will prompt for a pc name. The computer then becomes known in SCCM and is added to the correct collection(s). But if I want to reïnstall windows on a known computer things are different: I can do a required deployment of the imaging task sequence to the collection of computers. Then windows installs through PXE, without any human interaction, keeping the original computer name. But because the initial deployment was not required, the "required PXE deployment" flag is not set. So as soon as I add a new computer to a collection with a required PXE deployment, it will start to reïnstall windows again. I can also deploy the imaging task sequence to the new unknown computers as required, so the flag gets set initially. But then it does not prompt for a computer name. (and it generates a name like MININT-xxx) Which is also sort of what I want. Because when i want to re-install a machine, I want it to install without interaction. How can I solve this?

  • Why Does DreamWeaver CS5 Discriminate between File Extensions, Even After Modding Mime Types!?

    - by Sam
    Hi folks, Even After I forced DreamWeaver CS5 to allow opening of .ast extensions as a MIME type of php5, which DreamWeaver now opens and colors correctly as described here, I still have trouble figuring out why it still discriminates between the two file extensions! Symptoms: External Files & Design View I have a file foo.php which php includes other files (e.g. the php-combined css.php and js.php). Now, when opening foo.php all functions work perfectly: the external (included) php files are all recognised correctly. However, when I change foo.php foo.ast, and open it again, It does not recognise the files extensions anymore in the top bar. Also, I lose the Design / Live View functionality.** When I change foo.ast to foo.php, all works again! Anyone any clues of why there remains a a difference between one and other extension? Note1: I have added the .ast extension to these four files, next to .php: 1 C:\Users\Sam\AppData\Local\VirtualStore\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 2 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 3 C:\Users\Sam\AppData\Roaming\Adobe\Dreamweaver CS5\en_US\Configuration\Extensions.txt 4 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\Extensions.txt Note2: sometimes, even .php files do not want to show in design view or live view. Could this be caused by a corrupted installation?

  • Standards for documenting/designing infrastructure

    - by Paul
    We have a moderately complex solution for which we need to construct a production environment. There are around a dozen components (and here I'm using a definition of "component" which means "can fail independently of other components" - e.g. an Apache server, a Weblogic web app, an ftp server, an ejabberd server, etc). There are a number of weblogic web apps - and one thing we need to decide is how many weblogic containers to run these web apps in. The system needs to be highly available, and communications in and out of the system are typically secured by SSL Our datacentre team will handle things like VLAN design, racking, server specification and build. So the kinds of decisions we still need to make are: How to map components to physical servers (and weblogic containers) Identify all communication paths, ensure all are either resilient or there's an "upstream" comms path that is resilient, and failover of that depends on all single-points of failure "downstream". Decide where to terminate SSL (on load balancers, or on Apache servers, for instance). My question isn't really about how to make the decisions, but whether there are any standards for documenting (especially in diagrams) the design questions and the design decisions. It seems odd, for instance, that Visio doesn't have a template for something like this - it has templates for more physical layout, and for more logical /software architecture diagrams. So right now I'm using a basic Visio diagram to represent each component, the commms between them with plans to augment this with hostnames, ports, whether each comms link is resilient etc, etc. This all feels like something that must been done many times before. Are there standards for documenting this?

  • Excel controls not visible for certain users

    - by Nossidge
    One of the users of an Excel program I've written is having a weird problem. None of the control objects (Command Button, ComboBox, etc.) are visible to him when he opens the file on his laptop. He is using Excel 2003, the same version I used to create the program, and enables macros using the pop-up when the file loads. I have Googled this, and have found these people who seem to be having the exact same problem, with various versions of Excel. Unfortunately, none of their questions were answered. I can't really explain it any better than this user: If I enter design mode and pull a control from the control toolbar onto a sheet all I see are the drag handles. When not in design mode I have to feel around with the mouse and can click the button which executes the button click code correctly and opens another sheet where again I have to feel around for the buttons to return me to the original sheet. The button I managed to click is now visible but as soon as I click anywhere on the sheet it disappears. I have verified that the visible property of the buttons is set and that the Show All Objects on the Options View tab is selected. If I pull buttons from the Forms toolbar onto a sheet they are visible. If I try to find Objects using F5 when not in design mode Excel reports no objects on the sheet. So, Super Users, can you help? UPDATE: Thanks for your replies, but much like the person in the ozgrid link, the problem has gone away. Not sure why it went, but I can confirm that the user rebooted again and also started up other Excel files that didn't contain controls in the interim. Perhaps that fixed it, or maybe it'll be back again. I'll keep udating with progress, and close if the problem doesn't reoccur for the next few days. Thanks again.

  • Advantages of Migrating Flex3 App to Flex4

    - by Srirangan
    Hi guys, What are the advantages of migrating a Flex 3 app (Java backend, BlazeDS, Spring, Hibernate) to Flex 4? One of the biggest advantages of Flex 4 is design. Assuming that design / UI isn't a big driver for the business right now as compared to performance, what are the other factors we can highlight? We have implemented Cairngorm and Swiz on the App (with a gradual "roll out" of Cairngorm planned for the future). Any opinions? Thanks, Sri

  • SharpZip escape filename

    - by mr.moses
    I'm using SharpZipLib to create a zip file with an html page and images. If the html file has a / in the name, it creates a folder (which messes up the image paths). Example: If the html file should be named Web/Design.html the zip file will contain a Web folder with a Design.html file in it. I've tried escaping / by replacing / with // or \/ but nothing has worked so far.

  • Time Saving Minutiae

    - by Dave Jarvis
    What little tricks do you use to save time when developing? For example: In JDeveloper, change the default editor to Source view from Design view for JSP files.   Tools » Preferences » File Types » Default Editors » JSP Tag File By default, JDeveloper opens JSP files in Design view, which can take 10 to 15 seconds to begin editing a file. Opening files in Source view only takes 2 seconds.

  • How do I create a Solution Wide Connection String

    - by Renier
    Hi. Does anyone know if it is possible to create a single connection string that will be accessible to all the projects in a solution (we have about 6). I can create a text file with this information, but we need design time support as well, and it is not practical to have a connection string in every App.Config and Web.config file in the solution. We basically want a Single connection string that is easy to change should the location of the db change, that will also be used by the IDE for design time support Regards, Renier

  • Loading a Reusable UITableViewCell from a Nib

    - by Greg Martin
    I am able to design custom UITableViewCells and load them just fine using the technique described in the thread found at http://forums.macrumors.com/showthread.php?t=545061. However, using that method no longer allows you to init the cell with a reuseIdentifier which means you have to create whole new instances of each cell at every call. Has anyone figured out a good way to still cache particular cell types for reuses, but still be able to design them in Interface Builder?

  • How do I stop myself from redesigning my Silverlight screens? Is there a theme that looks like Sket

    - by Dan Ryan
    Whilst working in Silverlight I am always fighting the urge to work on the screen design rather than coding the behaviour (which is what I should be doing). My cunning plan is to find a theme that looks something like MS SketchFlow or Balsamiq which will remind me of the draft nature of the screens whilst being somewhat prettier than the default look & feel of Silverlight. Does anyone know of such a theme? Alternatively can anyone give advise on how they overcame there design addiction :) Thanks, Dan
