  • Window controls missing; Cannot maximise or minimize applications

    - by omg_scout
    Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

  • Skype, add-on applications, UAC and "Unable to respond"

    - by Greg Low
    Just posting this blog tonight hoping it might save someone else a bunch of time. For call recording on Skype, I use a program called Pamela. Lately, when I'd first installed it, it would work fine. Later, however, it would come up and say: "Another application (Pamela.exe) is attempting to access Skype, but we are unable to respond". You just have to love these sorts of messages that don't give you the slightest clue about what the problem is. While I saw the problem with Pamela, it can happen with...(read more)

  • How to customize web-app (pages and UI) for different customers

    - by demoncodemonkey
    We have an ASP.NET web-application which has become difficult to maintain, and I'm looking for ideas on how to redesign it. It's an employee administration system which can be highly customized for each of our customers. Let me explain how it works now: On the default page we have a menu where a user can select a task, such as Create Employee or View Timesheet. I'll use Create Employee as an example. When a user selects Create Employee from the menu, an ASPX page is loaded which contains a dynamically loaded usercontrol for the selected menuitem, e.g. for Create Employee this would be AddEmployee.ascx If the user clicks Save on the control, it navigates to the default page. Some menuitems involve multiple steps, so if the user clicks Next on a multi-step flow then it will navigate to the next page in the flow, and so on until it reaches the final step, where clicking Save navigates to the default page. Some customers may require an extra step in the Create Employee flow (e.g. SecurityClearance.ascx) but others may not. Different customers may use the same ASCX usercontrol, so in the AddEmployee.OnInit we can customize the fields for that customer, i.e. making certain fields hidden or readonly or mandatory. The following things are customizable per customer: Menu items Steps in each flow (ascx control names) Hidden fields in each ascx Mandatory fields in each ascx Rules relating to each ascx, which allows certain logic to be used in the code for that customer The customizations are held in a huge XML file per customer, which could be 7500 lines long. Is there any framework or rules-engine that we could use to customize our application in this way? How do other applications manage customizations per customer?

  • Hosting cross-domain Silverlight applications (XAP)

    In the Silverlight world, there are two types of cross-domain things that may leave some banging their head against a wall for a while. The first involves making network-based calls (WebClient, HttpWebRequest, etc) to services hosted on a domain other than the one that is the site of origin for the XAP. This is solved by ensuring the service provider enables a clientaccesspolicy.xml file for their service. More information here: Cross Domain Policy Files with Silverlight. NOTE: site of origin is...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Styling Windows Phone Silverlight Applications

    - by Tim Murphy
    If you have not developed with styles in Silverlight/XAML then it can be challenging and resources can be sparse depending on how deep you get.  One thing that you need to understand is what level you can apply styles and how much they can cascade.  What I am finding is that this doesn’t go to the level that we are used to in HTML and CSS. While styles can be defined at a page level if you want to share styles throughout your application they should be defined in the App.xaml file.  This is of course analogous to placing a style in your HTML file versus an external CSS file.  This is the type of style I will concentrate on in this post. The first thing to look it how styles associate to elements.  TargetType defines the object type that your style will apply to.  In the example below the style is targeting the TextBlock object type. <Style x:Key="TextBlockSmallGray" TargetType="TextBlock"> Next we use a Setter which allows you to apply values for specific attributes of the target object type.  The setters can be a simple value or complex.  The first example here is simply applying a color to the background property of the target. <Setter Property="Background" Value="White"/> The second setter example here is for the same property, but we are applying a the definition of a LinearGradientBrush. <Setter Property="Background"> <Setter.Value> <LinearGradientBrush> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset="1" Color="White"/> </LinearGradientBrush> </Setter.Value> </Setter> The last thing I want to cover here is that you can leverage the system styles and then override or extend them.  The BasedOn attribute of the Style tag allows this sort of inheritance.  In the example below I am going to start with the PhoneTextTitleStyle and then override properties as needed. <Style x:Key="TextBlockTitle" BasedOn="{StaticResource PhoneTextTitle1Style}" TargetType="TextBlock"> So now that we have our styles defined applying it is fairly straight forward.  Add the style name as a static resource to the style property of the element in your page and off you go. <Grid x:Name="LayoutRoot" Style="{StaticResource PageGridStyle}"> So this is one step in creating consistency in your application’s look.  In future posts I will dig a little deeper. del.icio.us Tags: windows phone 7,mobile development,windows phone 7 development,.NET,software development,design,UX

  • Google Drive terminates without error on startup

    - by Iszi
    I've used Google Drive for awhile now, but it won't start up after installing on my latest system re-build. I'm still using the same OS, hardware, and basic software load (antivirus, firewall, etc.) that I have for years during which I had not previously had problems with Drive. OS: Windows 7 Ultimate x64 Google Drive Version: 1.12.5329.1887 Now, whenever I try to run Google Drive, it just spawns two instances of the executable which die shortly after. No error messages are posted to the desktop, and nothing indicating any problem is written to the Event Log. After some research, I've yet to find anyone having the same problem who's found an answer. I did find out how to run Google Drive in diagnostic mode, using the --vv parameter at the command line. After that, I opened up the sync log and got this: 2013-10-31 17:11:24,039 INFO pid=3664 1892:MainThread logging:1600 OS: Windows/6.1.7601-SP1 2013-10-31 17:11:24,039 INFO pid=3664 1892:MainThread logging:1600 Google Drive (build 1.12.5329.1887) 2013-10-31 17:11:24,039 DEBUG pid=3664 1892:MainThread logging:1608 DEBUGGING DUMP is ON. 2013-10-31 17:11:24,051 ERROR pid=3664 1892:MainThread logging:1575 ERROR, UNEXPECTED EXCEPTION 2013-10-31 17:11:24,051 ERROR pid=3664 1892:MainThread logging:1575 [Error 5] Access is denied Traceback (most recent call last): File "<string>", line 232, in Main File "<string>", line 118, in RegisterCustomFileTypes File "P:\p\agents\hpal4.eem\recipes\353983091\base\b\drb\googleclient\apps\webdrive_sync\windows\build\pyi.win32\main\outPYZ1.pyz/windows.registry", line 62, in GetValue WindowsError: [Error 5] Access is denied 2013-10-31 17:11:24,052 INFO pid=3664 1892:MainThread logging:1600 Crash reporting disabled.

  • Which forum applications can integrate with Facebook? [closed]

    - by deathlock
    EDIT: I don't think this is a duplicate... I ask for a specific feature, which is Facebook integration. I know this question existed, but I need something more specific than that. That one doesn't outline what I need. What is the best/most compatible forum software which features almost complete integration with Facebook? The main feature I ask is the Facebook Connect feature (user could use Facebook account to register). But it would be more perfect if other Facebook features could be integrated to. Something like, subscribe thread which appears to Facebook notifications, easy sharing to Facebook, etc. I have vBulletin, Invision Power Board, and SMF in my mind, but I'm open to more suggestions..

  • amavisd Net server pid file already exists after system crash and startup

    - by Simiyu
    Hi all, whenever i have an unclean shutdown, which is often due to power failure most of the time i get problems with amavis starting up. The error amavisd Net server pid_file already exists for running process comes when i start it under debug mode, so i always have to delete the amavisd.pid and amavisd.lock files manually before it starts. Is there a way i can stop this from happening or get a way to delete the files during reboot in the case of an unclean shutdown. Thanks

  • Stuff to read up on pricing applications

    - by tux91
    I'm about to release an app and I have no idea what would be the ideal pricing point. I'm not sure how pricing high and selling few copies will compare in revenue to pricing low and selling lots of copies in my case. Can somebody point me to books/articles/blog posts/etc that elaborate on the subject, preferably taking into account stuff like competition, number of features, being the first one to the market, research if this kind of app is even needed, etc?

  • Installing VMWare Tools in Windows Server 2008 fails system startup

    - by Hoghweed
    I recently created a vmware virtual machine with windows server 2008 enterprise as Guest. My host is Ubuntu 10.04 on my Lenovo laptop. I fall into a big trouble which makes my created VM unusable after I've installed VMWare Tools. After installing tools I'm able to run the system only in safe mode. After some event manager analysis I found the issue is with drivers installed by vnmware tools. Any one has got the same issue? Is there any good practice for doing that? The configuration of vm machine is the following CPU : 1 RAM : 1020 HD : 40GB Splitted files, SCSI CD : IDE Thanks in advance

  • startup cassandra layout

    - by davidkomer
    We've got a relatively low-traffic site (~1K pageviews/day) hosted on a single server, and expect it to grow significantly over the next few years. I'm thinking of moving over to Rackspace CloudServer or EC2 and firing up 3 nodes (all on CentOS): 2 x Web (Apache) - with loadbalancer 1 x MySQL (for the Wordpress powered part) The question is where to put Cassandra right now... Should it sit on each Web node, or the MySQL node? My thought right now is to put it on Web nodes. It's my understanding that Cassandra has the benefits of fault-tolerance (i.e. if we take a node down, the site is still operational). So even with only 2 nodes, we'd have that benefit as opposed to just putting it on the MySQL node. Also, as we scale up and add another node, a cassandra instance can come along with it and the php can always run its queries on localhost. Is this a good idea?

  • Designing call center applications, what to consider.

    - by Espen Schulstad
    We have customers calling in to place orders. What sort of considerations should I make when building a call center application. Speed is a factor here. We had a powerbuilder application that was extremly fast for a trained user. We want to have the same sort of speed in our new production system. So some thoughts I've made are: Hotkeys are important. Is it faster to use a "wizard", step by step, or should I try to place everything important about the order logically on one sceen and have another screen where you do all searches, pertinent for that order?
