• Disabled annotation tools in Skim

  - by Kit

  Here's a portion of the toolbar in Skim In the Add Note section, why are the following tools disabled (dimmed)? Add New Highlight (A in the yellow box) Add New Underline (red line under A) Add New Strike Out (A struck out by red line) However, in the Tool Mode section, there is a drop down button (shown as active in the screenshot). To illustrate, I can select and use the Add New Underline tool, as well as the other tools I mentioned above, using the drop down button. But those tools are dimmed out in the Add Note section. Why? I have observed that the drop down button is just a duplicate of the Add Note section. Why not just enable all the buttons in the Add Note section and save the user from making an extra click just to bring down a list of tools? Is this because of some property of the presently open PDF, or what?

• VirtualBox: How to connect to Internet via wi-fi on Mac?

  - by Paul Riedel

  I installed VirtualBox with a Win XP VM on my Mac running OS 10.7.5. My Mac only has a wi-fi connection to the internet. On the settings for the virtual host, I set: Attached to: Bridged Adapter Name: en1: Wi-Fi (AirPort) Adapter Type: Intel PRO/1000 MT Desktop (82540EM) Promiscuous Mode: Deny Mac Address: Cable Connected: true Those are the settings I see around the internet as being correct, but I still can't ping anything. On my Mac I have internet sharing via Ethernet enabled (not sure if that matters). When I start up my WinXP VM, it asks me to install a bunch of hardware which I don't have any drivers to. Do I need to install any ethernet card drivers in order for the internet to work? Thank you!!

• Swing: Multiple CellEditors for a column

  - by Luhar

  Hi, In my JTable, I have two editable numeric columns. The editor for both columns extends AbstractCellEditor and uses a JFormattedTextField as an the editing component. The problem is that the format for input depends on the value of another column in the row. If condition X is met, the number of fraction digits should be Y, otherwise they should be Y+2. I attempted to override the getTableCellEditor(..) method to associate a TableCellEditor per row. See this example. However, since I have two editable columns, sharing a single TableCellEditor object per row gives some very odd results. I don't think this is an appropriate solution. Any ideas on how to approach this would be much appreciated! Thank you!

• Altering specific configuration values in the On-Screen Keyboard of Windows 7

  - by fnst

  I have to use the On-Screen Keyboard of Windows 7 for typing: (In case you haven't used it yet, you can get it via: All Programs - Accessories - Ease of Access - On-Screen Keyboard or simply search for "osk.exe") It offers a feature to "hover" about the buttons. Microsoft describes it as the following: In hovering mode, you use a mouse or joystick to point to a key for a predefined period of time, and the selected character is typed automatically. There is my specific problem. The predefined period of time is too long to be useful for me. The minimum amount of time is 0.5 seconds (max. 3 seconds). Is there any way to alter this value to something < 0.5? For example via editing the registry? Edit: The entry *'HKEY_CURRENT_USER\Software\Microsoft\Osk\HoverPeriod'* cannot be set lower than 500 ms. Any helpful tip would be great!

• Multiple user database design

  - by dieguitoweb

  I have to develop a basic social network for an academic purpose; but I need some tips for the users management.. The users are subdivided into 3 groups with different privilege: admins,analysts and standards users. For every user should be stored into the database the following information: name,lastname,e-mail,age,password. I'm not quite sure how I should design the database between theese two solutions: 1)one table called 'users' with the 'role' attribute that explain what a user can do and what can't do, and the permissions are managed via php 2)every application user is a database user created with the query 'CREATE ROLE' (It's a postgres database) and he has permissions on some tables granted with the 'GRANT' statement You should take into account that the project is for a database exam.. thanks

• Which PHP calendar will suit my needs? Or build my own?

  - by John

  There are so many web based calendars out there that I'm not sure which will best suit my purposes. I want to create an events calendar, which I suppose looks and functions in much the same way as google calendar. But users shouldn't need to sign up for a gmail account or a google account. Users of my social network website should be able to create events in the calendar and share it with other friends in their "friend network". In month, year or day views, you can mouse hover events to see a bubble dialog that lists events in detail. People need to pay a monthly fee to use my website (not sure if this prevents me from using google apps). So is something like Google Calendar the way to go? Or are there other php/javascript calendars out there that already meet my needs? Or will it just save me more time to build my own?

• PHP image resize on the fly vs storing resized images

  - by Pablo

  I'm building a image sharing site and would like to know the pros and cons of resizing images on the fly with php and having the resized images stored. Which is faster? Which is more reliable? how big is the gap between the two methods in speed and performance? Please note that either way the images go through a PHP script for statistics like views or if hotlinking is allow etc... so is not like it will be a direct link for images if i opt to store the resize images. I'll appreciated your comments or any helpful links on the subject, Thanks.

• What features do you expect from a Java (Rich) Client Framework?

  - by Peter Walser

  I'm intending to design (and provide a reference implementation for) a new Swing Rich Client Framework. My job and personal experience covers many project-specific Swing client frameworks as well as the Eclipse RCP, and every one of them had some original and clever concepts, but also drawbacks and rigid realizations. My plan is to incorporate the best of those concepts and features into a new framework whose core is very open and extendable. For my must-have-features list, I'm counting on your input and hope you can share some concept pearls & diamonds you've encountered in other frameworks, or features you always wanted to have or have in a better way. The framework is intended for very simple to very complex and sophisticated projects for clients that need full i18n for richt clients that execute some or all of the non-presentation logic on the server to be very lightweight to be easy to learn and use Thanks in advance for sharing your insights :)

• Seeking easy to use Setup creator with logic and ability to write registry keys

  - by Mawg

  I want to create a Setup to install my application. It as to be able to do the following: ask a question (maybe 2 radio buttons?) and, depending on the reply, copy one of 2 DLLs to the Windows directory and invoke regsvr to register the DLL write some registry keys I would code my own program to do this, but I don't have enough knowledge of the different versions of Windows (XP, Vista, 7, etc) and 32/64 bit, registry layout, or permissions like UAC, etc So, it seems to me that it would be easier to use a Setup generator which has been around for a while and already handles all of this stuff. I went to my favorite site for free stuff and found this page. However, the programs mentioned there are either too simplistic or have too steep a learning curve for me. Can anyone recommend a Goldilocks solution which does what I mentioned in those two bullet points while taking into account all Windows versions, 32/64 bit, non-admin accounts, etc?

• Possible to implement an IsViewPortVisible dependencyproperty for an item in an ItemsControl?

  - by Matt H.

  I need to enable/disable spell checking in a richtextbox in an ItemsControl, based on whether the RichTextBox is visible in the ItemsControl's Scrollviewer. I think the route is to implement an IsViewPortVisible dependency property and wire an event handler for a changed event... I found this article that describes the lengthy process for determining if an item is in the viewport: http://social.msdn.microsoft.com/Forums/en/wpf/thread/e6ccfec3-3dc0-4702-9d0d-1cfa55ecfc90 Any ideas on where to start? I'm familiar with implementing my own dependency property for the sake of simple bindings (integers, strings, etc...). I have no idea how to undergo something like this though) This is the end result I'm hoping for: <DataTemplate> <Grid> ...Stuff in the Grid <local:CustomRichTextBox SpellCheck.IsEnabled={Binding RelativeSource={RelativeSource Self}, Path=IsViewPortVisible}/> </Grid> </DataTemplate> Help will be EXTREMELY appreciated... you'll be saving me about 500MB in memory consumption while the program is running!!!! :)

• Could/Should I use static classes in asp.net/c# for shared data?

  - by death.au

  Here's the situation I have: I'm building an online system to be used by school groups. Only one school can log into the system at any one time, and from that school you'll get about 13 users. They then proceed into a educational application in which they have to co-operate to complete tasks, and from a code point of view, sharing variables all over the place. I was thinking, if I set up a static class with static properties that hold the variables that are required to be shared, this could save me having to store/access the variables in/from a database, as long as the static variables are all properly initialized when the application starts and cleaned up at the end. Of course I would also have to put locks on the get and set methods to make the variables thread safe. Something in the back of my mind is telling me this might be a terrible way of going about things, but I'm not sure exactly why, so if people could give me their thoughts for or against using a static class in this situation, I would be quite appreciative.

I thought about some database that holds and iterate and check if the thread is active, but it seems clumsy. is there a better way? thanks

• How do I program a hardware button on my laptop?

  - by daniel11

  So I have a set of touch screen buttons on the top of my laptop's keyboard, (one turns on power save mode, one disables/enables the mouse touch pad, one toggles the wifi adapter, and two turns the volume up/down). However there's another one that opened a file backup utility that came with my laptop. Since I bought my laptop, I've uninstalled that utility, rendering this button useless. Would it be possible to reprogram that button to open another file or program on my computer? And if so, what are the requirements and how would I go about doing it? Thanks in advance!

• Can't connect to MySQL database hosted in CloudBees

  - by user3692698

  I have a free CloudBees account and created a free ClearDB database using their wizards. My trouble is when I use their connection information (whether I try to connect from my Java app, or an outside tool - SQLyog to be exact) I take the error: Access denied for user 'b51dbc5757d79f'@'%' to database 'mywiki. The username provided by CloudBees does not contain those extra characters that the error message is displaying which seems like it would be a problem, but I'm not sure there is anything I can do about that since everything is configured for me. The username I am given is: b51dbc5757d79f - which I can delete and rebuild after sharing here :)

• Forking Public GitHub Code that is also Sold as a Complied App

  - by Ryan Castillo

  I found a public repo on GitHub that I would like to play around with. I can see myself potentially spending a lot of time writing tests for it and expanding its functionality. The code is also being sold as an app. I have no problem with this because I admire the owner's practice of sharing his source and also providing the convenience of paying for the app for users who don't want to mess with compiling it. If I was to spend time with this code as a separate fork what would prevent the owner from merging it with his master branch? Is it ethical for him to still profit off of my added functionality? Should a line be drawn somewhere?

• How to add network printer remotely without knowing the IP?

  - by Steve

  Assume your friend from over 100km away asked you to add a network printer to his computer since you're so tech savvy. How would you add network printer remotely in this case? You would need: 0. Remote connection to your friend's computer 1. Printer IP and brand/model names 2. Respective drivers downloaded either from manufacturer's website or Windows Update driver Question is, how would you find out the IP address of the printer without bothering your friend too much with technical steps? Since your friend isn't as tech savvy as you - they wouldn't know which buttons to press to get IP address.

• Cross Domain Cookies Problem (ASP.NET)

  - by Laserson

  Hi guys, i have a problem with cross-domain cookies. I read a lot of documentation about sharing cookies between subdomains. The main idea of all articles is set Domain property to something like ".mydomain.com". I've created two domains on local IIS server - test1.local.boo and test2.local.boo. They works great and visible with browser. I have the following code: Site test1 - Writes cookie: HttpCookie myCookie = new HttpCookie("TestCookie"); myCookie.Domain = ".local.boo"; myCookie["msg"] = "Welcome from Cookie"; Response.Cookies.Add(myCookie); Site test2 - Reads cookie: HttpCookie cookie = Request.Cookies["TestCookie"]; if (cookie != null) { Response.Write(cookie["msg"]); } else { Response.Write("FAILED"); } This code always shows FAILED message. So it means that second site can't read cookie from the same subdomain. Where is my mistake??

• How do I setup a shared session between two users on my Ruby on Rails powered site?

  - by ben

  Hey guys, The website that I'm building includes a section where two users can interact. I think I know how to do most of it, except the actual session sharing part. I'm using Ruby on Rails & Javascript (jquery), and I've got user login and session management all working okay. Would the best way to create a shared session be to have a SharedSession model, with accompanying database table, with participant1ID, participant2ID etc? Is there a better way? Thanks so much for reading!

• sqlite3.OperationalError

  Hi, The "python manage.py syncdb" command is giving me the following error: sqlite3.OperationalError: unable to open database file I'm following the step by step instructions in Practical Django Projects, so I think this has to do something with the Windows Operating system acting quirky! Things I've checkde: 1.The path is updated in settings.py is absolutely correcto! 2. Path is : C:\Documents and Settings\fixavier\Desktop\Django\Database\cms\cms.txt So the entire folder - Database, has sharing and security permissions. I'm pretty much at the bottom of the ocean for not being able to follow and successfully execute simple instructions, so could you please help me out here!

• What would be my best MySQL Synchronization method?

  - by Kerry

  We're moving a social media service to be on separate data centers with global load balancing, as our other hosting provider's entire data center went down. Twice. This means that both websites need to be synchronized in some sense -- I'm less worried about the code of the pages, that's easy enough to sync, but they need to have the same database data. From my research on SO, it seems MySQL Replication is a good option, but the MySQL manual, for scaling out, says that its best when there are far more reads then there are writes/updates: http://dev.mysql.com/doc/refman/5.0/en/replication-solutions-scaleout.html In our case, it's about equal. We're getting around 200-300 thousand requests a day right now, and we can grow rapidly. Every request is both a read and write request. What would be the best method or tool to handle this?

• Keyboard shortcut to cycle through programs (rather than just the alt-tab switch)?

  - by Steven Lu

  This question applies to both Windows and Mac OS X because I intend to use my mouse (Logitech G700) with both of them. The idea is I want one of my configurations to use two of my buttons to switch applications. However binding them to Alt/Cmd+Tab and Shift+Alt/Cmd+Tab is not good because the former functions as a toggle, and the latter cycles (in an unpredictable order). What I want is to move through my open applications in a circular buffer order. Do either of these OS's provide any keyboard shortcut that accomplishes this? I could live with just Alt/Cmd+Tab set to one button, but it limits me to being able to switch between only two programs.
