  • SQL SERVER – Reset SA Password – SQL in Sixty Seconds #066

    - by Pinal Dave
    It has been quite a long time since I posted SQL in Sixty Seconds Video. Here we are back with the new video. One of the most popular question, I often receive is very similar to following: “How do I reset the password for SA username?” “I have forgotten the SA password, what should I do?” “Our DBA just left the job and now noone knows how to reset the SA password. Please help.” Solution Honestly, it is pretty simple to reset the password for SA username. You just have to login to the system where your SQL Server is installed. Open SQL Server Management Studio and login with the help of Windows Authentication. As local system is the admin of the SQL Server, you will get access with administration privileges. Now, open the database, expand Security >> Login folder and right click over SA username. Now, it will bring up the screen where you can change the password for SA. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password. You can read it over here:  SQL SERVER – Forgot the Password of Username SA Change Password of SA Login Using Management Studio You can subscribe to my YouTube Channel for frequent updates.

  • Building Web Applications with ACT and jQuery

    - by dwahlin
    My second talk at TechEd is focused on integrating ASP.NET AJAX and jQuery features into websites (if you’re interested in Silverlight you can download code/slides for that talk here). The content starts out by discussing ScriptManager features available in ASP.NET 3.5 and ASP.NET 4 and provides details on why you should consider using a Content Delivery Network (CDN).  If you’re running an external facing site then checking out the CDN features offered by Microsoft or Google is definitely recommended. The talk also goes into the process of contributing to the Ajax Control Toolkit as well as the new Ajax Minifier tool that’s available to crunch JavaScript and CSS files. The extra fun starts in the next part of the talk which details some of the work Microsoft is doing with the jQuery team to donate template, globalization and data linking code to the project. I go into jQuery templates, data linking and a new globalization option that are all being worked on. I want to thank Stephen Walther, Dave Reed and James Senior for their thoughts and contributions since some of the topics covered are pretty bleeding edge right now.The slides and sample code for the talk can be downloaded below.     Download Slides and Samples

  • Can I legally publish my Fortran 90 wrappers to nVidias CUFFT library (from CUDA SDK)?

    - by Jakub Narebski
    From a legal standpoint (licensing issues), can I legally in agreement with license publish Fortran 90 wrappers (bindings) to CUFFT library from nVidia CUDA Toolkit, under some open source license (either CC0 i.e. public domain, or some kind of permissive license like BSD). nVidia provides only C bindings with their CUDA SDK.

  • Twin Cities Code Camp 8 Retrospective

    - by Lee Brandt
    I just got back (a few hours ago) from Minneapolis, where I was speaking at the Twin Cities Code Camp 8. I’d never been to a Twin Cities Code Camp, and I have always heard such great things, so I submitted and got accepted to speak. The conference (what I got to see) was great. My talk was pretty short on people, but there are many reasons for that. First, I spoke opposite Donn Felker (speaking about developing for Android) and Keith Dahlby (speaking about Dynamic .NET). So of course, my talk is going to be empty. How could I compete with that? Plus, my talk was about software process improvement, specifically about how our process has evolved. Maybe not the smartest idea to submit to talk about software process at a developer’s conference. The people who DID attend however, seemed to really enjoy the talk. There was good interaction and good, thoughtful questions. So the attendees seemed engaged. I actually did get a chance to go to one session. I went and saw Javier Lozano talk about Open source tools for ASP.NET MVC. I am hip-deep in MVC stuff right now and getting up to speed on MVC 2 as well. I learned about MVC Turbine, Javier’s Open Source project. I will definitely be adding it to my MVC arsenal. Thanks Javier! I did forget my AC adapter for my laptop and got a little lost in Minneapolis on my way to get one from MicroCenter Saturday morning, but other than that, it was a great trip. It’s a long drive, but seeing all the guys and getting two Nut & Honey rolls from Roly Poly in Eden Prarie for lunch on Saturday made the trip totally worth it. I look forward to seeing what Jason & Chris come up with for next year! Thanks for having me guys!

  • Ubuntu 11.10 is falling back to Unity 2D. How to get back to Unity 3D?

    - by marcioAlmada
    It happened some minutes ago when I plugged my secondary monitor and my graphical interface simply crashed. So I had to restart my session. Since the crash Ubuntu insists to use Unity2D fall back instead of the default one. I used to plug the secondary monitor everyday when at home and nothing bad happened before.

  • Rolling your own Hackathon

    - by Terrance
    Background Info Hey, I pitched the idea of a company Hackathon that would donate our time to a charity to work on a project (for free) to improve morale in my company and increase developer cohesion. As it turns out most like the idea but, guess who's gonna be the one to put it together. lol Yeah me. I should add that we are a fairly small shop with about 10-12 programmers (some pull double duty as programmers, inters etc..) So, that might make things a bit easier. Base Question While I am no means a project manager or of any level of authority (Entry level guy) I was wondering if anyone knew the best approach for someone in my position to put together such an even with possibly (some) company backing. Or for that matter have any helpful advice to pass along to a young padawan. So far..... As of right now it is just an idea so, to start with I presumably would have to put together some sort of proposal and do some that office stuff that I became a programmer to steer clear of to some extent.

  • LibreOffice - Can't drag and replace images [LibreOffice 3.5 and 3.6, Ubuntu 12.04]

    - by Anderxale
    My wife uses LibreOffice to create catalogues of a couple hundred items and then converts it to PDF. Man we love LibreOffice! Anyway I set up Windows-7 and Mint-14-Mate dual boot for her to ease into Linux. Today she was ready for Ubuntu and so I did a clean install on her machine. Everything was smooth but today when she tried to work she ran into an issue... She used to be able to download a folder full of images to use in her catalogues and then update her catalogues by replacing old images with new ones. It was so simple - Open an old catalogue, save with a new date, drag and drop replace images of items that no longer exist. The drag and drop process would scale the image and then crop it horizontally or vertically to fit. Now that I have installed Ubuntu 12.04 for her she can no longer replace images, it just does nothing... If she drags the image to the left or right of the original it appears next to the original so I know d&d works, unfortunately it does not resize or crop the image. I tried this on my laptop and my desktop... same thing! I then tried updating the LibreOffice to 3.6, no change. I then tried opening a virtual machine windows xp and Mint 14 on this computer and tried with 3.6 in those operating systems and it worked. Can anyone help? I have a lot of hope that there is an answer because Mint is based on Ubuntu/Debian and that distro can perform this task successfully! Sorry about writing a book....

  • Tuning Red Gate: #5 of Multiple

    - by Grant Fritchey
    In the Tuning Red Gate series I've shown you how to look at a current load on the system and how to drill down to look at historical analysis of the system. I've also shown how you can see the top queries and other information from the current status of the system. I have one more thing I can show you before we need to start fixing things and showing how that affects the data collected, historical moments in time. For example, back in Post #3 I was looking at some spikes in some of the monitored resources that were taking place a couple of weeks back in time. Once I identify a moment in time that I'm interested in, I can go back to the first page of Monitor, Global Overview, and click on the icon: From this you can select the date and time you're interested in. For example, I saw some serious CPU queues last week: This then rolls back the time for all the information that's available to the Global Overview and the drill down to the server and the SQL Server instance there. This then allows me to look at the Top Queries running at this point, sort them by CPU and identify what was potentially the query that was causing the problem right when I saw the CPU queuing This ability to correlate a moment in time with the information available to you in the Analysis window makes for an excellent tool to investigate your systems going backwards in time. It really makes a huge difference in your knowledge. It's not enough to know that something happened at a particular time. You need to know what it was that was occurring. Remember, the key to tuning your systems is having enough knowledge about them. I'll post more on Tuning Red Gate as soon as I can get some queries rewritten. I'm working on that.

  • Dell Docking Station Doesn’t Detect USB Mouse and Keyboard

    - by Ben Griswold
    I’ve found myself in this situation with multiple Dell docking stations and multiple Dell laptops running various Windows operating systems.  I don’t know why the docking station stops recognizing my USB mouse and keyboard – it just does.  It’s black magic.  The last time around I just starting plugging the mouse and keyboard into the docked laptop directly and went about my business (as if I wasn’t completing missing out on a couple of the core benefits of using a docking station.)  I guess that’s what happens when you forget how you got yourself out of the mess the last time around.  I had been in this half-assed state for a couple of weeks now, but a coworker fortunately got themselves in and out of the same pickle this morning.  Procrastinate long enough and the solution will just come to you, right? Here’s how to get yourself out of this mess: Undock your computer Unplug your docking station Count to an arbitrary number greater than 12.  (Not sure this is really required, but…) Plug your docking station back in Redock your machine I put my machine to sleep before taking the aforementioned actions.  My coworker completely shutdown his laptop instead.  The steps worked on both of our Win 7 machines this morning and, who knows, it might just work for you too.

  • Visual Studio 2010 Productivity Tips and Tricks-Part 2: Key Shortcuts

    - by ToStringTheory
    Ask anyone that knows me, and they will confirm that I hate the mouse.  This isn’t because I deny affection to objects that don’t look like their mammalian-named self, but rather for a much more simple and not-insane reason: I have terrible eyesight.  Introduction Thanks to a degenerative eye disease known as Choroideremia, I have learned to rely more on the keyboard which I can feel digital/static positions of keys relative to my fingers, than the much more analog/random position of the mouse.  Now, I would like to share some of the keyboard shortcuts with you now, as I believe that they not only increase my productivity, but yours as well once you know them (if you don’t already of course)...  I share one of my biggest tips for productivity in the conclusion at the end. Visual Studio Key Shortcuts Global Editor Shortcuts These are shortcuts that are available from almost any application running in Windows, however are many times forgotten. Shortcut Action Visual Studio 2010 Functionality Ctrl + X Cut This shortcut works without a selection. If nothing is selected, the entire line that the caret is on is cut from the editor. Ctrl + C Copy This shortcut works without a selection. If nothing is selected, the entire line that the caret is on is copied from the editor. Ctrl + V Paste If you copied an entire line by the method above, the data is pasted in the line above the current caret line. Ctrl + Shift + V Next Clipboard Element Cut/Copy multiple things, and then hit this combo repeatedly to switch to the next clipboard item when pasting. Ctrl + Backspace Delete Previous Will delete the previous word from the editor directly before the caret. If anything is selected, will just delete that. Ctrl + Del Delete Next Word Will delete the next word/space from the editor directly after the caret. If anything is selected, will just delete that. Shift + Del Delete Focused Line Will delete the line from the editor that the caret is on. If something is selected, will just delete that. Ctrl + ? or Ctrl + ? Left/Right by Word This will move the caret left or right by word or special character boundary. Holding Shift will also select the word. Ctrl + F Quick Find Either the Quick Find panel, or the search bar if you have the Productivity Power Tools installed. Ctrl + Shift + F Find in Solution Opens up the 'Find in Files' window, allowing you to search your solution, as well as using regex for pattern matching. F2 Rename File... While not debugging, selecting a file in the solution explorer\navigator and pressing F2 allows you to rename the selected file. Global Application Shortcuts These are shortcuts that are available from almost any application running in Windows, however are many times forgotten... Again... Shortcut Action Visual Studio 2010 Functionality Ctrl + N New File dialog Opens up the 'New File' dialog to add a new file to the current directory in the Solution\Project. Ctrl + O Open File dialog Opens up the 'Open File' dialog to open a file in the editor, not necessarily in the solution. Ctrl + S Save File dialog Saves the currently focused editor tab back to your HDD/SSD. Ctrl + Shift + S Save All... Quickly save all open/edited documents back to your disk. Ctrl + Tab Switch Panel\Tab Tapping this combo switches between tabs quickly. Holding down Ctrl when hitting tab will bring up a chooser window. Building Shortcuts These are shortcuts that are focused on building and running a solution. These are not usable when the IDE is in Debug mode, as the shortcut changes by context. Shortcut Action Visual Studio 2010 Functionality Ctrl + Shift + B Build Solution Starts a build process on the solution according to the current build configuration manager settings. Ctrl + Break Cancel a Building Solution Will cancel a build operation currently in progress. Good for long running builds when you think of one last change. F5 Start Debugging Will build the solution if needed and launch debugging according to the current configuration manager settings. Ctrl + F5 Start Without Debugger Will build the solution if needed and launch the startup project without attaching a debugger. Debugging Shortcuts These are shortcuts that are used when debugging a solution. Shortcut Action Visual Studio 2010 Functionality F5 Continue Execution Continues execution of code until the next breakpoint. Ctrl + Alt + Break Pause Execution Pauses the program execution. Shift + F5 Stop Debugging Stops the current debugging session. NOTE: Web apps will still continue processing after stopping the debugger. Keep this in mind if working on code such as credit card processing. Ctrl + Shift + F5 Restart Debugging Stops the current debugging session and restarts the debugging session from the beginning. F9 Place Breakpoint Toggles/Places a breakpoint in the editor on the current line. Set a breakpoint in condensed code by highlighting the statement first. F10 Step Over Statement When debugging, executes all code in methods/properties on the current line until the next line. F11 Step Into Statement When debugging, steps into a method call so you can walk through the code executed there (if available). Ctrl + Alt + I Immediate Window Open the Immediate Window to execute commands when execution is paused. Navigation Shortcuts These are shortcuts that are used for navigating in the IDE or editor panel. Shortcut Action Visual Studio 2010 Functionality F4 Properties Panel Opens the properties panel for the selected item in the editor/designer/solution navigator (context driven). F12 Go to Definition Press F12 with the caret on a member to navigate to its declaration. With the Productivity tools, Ctrl + Click works too. Ctrl + K Ctrl + T View Call Hierarchy View the call hierarchy of the member the caret is on. Great for going through n-tier solutions and interface implementations! Ctrl + Alt + B Breakpoint Window View the breakpoint window to manage breakpoints and their advanced options. Allows easy toggling of breakpoints. Ctrl + Alt + L Solution Navigator Open the solution explorer panel. Ctrl + Alt + O Output Window View the output window to see build\general output from Visual Studio. Ctrl + Alt + Enter Live Web Preview Only available with the Web Essential plugin. Launches the auto-updating Preview panel. Testing Shortcuts These are shortcuts that are used for running tests in the IDE. Please note, Visual Studio 2010 is all about context. If your caret is within a test method when you use one of these combinations, the combination will apply to that test. If your caret is within a test class, it will apply to that class. If the caret is outside of a test class, it will apply to all tests. Shortcut Action Visual Studio 2010 Functionality Ctrl + R T Run Test(s) Run all tests in the current context without a debugger attached. Breakpoints will not be stopped on. Ctrl + R Ctrl + T Run Test(s) (Debug) Run all tests in the current context with a debugger attached. This allows you to use breakpoints. Substitute A for T from the preceding combos to run/debug ALL tests in the current context. Substitute Y for T from the preceding combos to run/debug ALL impacted/covering tests for a method in the current context. Advanced Editor Shortcuts These are shortcuts that are used for more advanced editing in the editor window. Shortcut Action Visual Studio 2010 Functionality Shift + Alt + ? Shift + Alt + ? Multiline caret up/down Use this combo to edit multiple lines at once. Not too many uses for it, but once in a blue moon one comes along. Ctrl + Alt + Enter Insert Line Above Inserts a blank line above the line the caret is currently on. No need to be at end or start of line, so no cutting off words/code. Ctrl + K Ctrl + C Comment Selection Comments the current selection out of compilation. Ctrl + K Ctrl + U Uncomment Selection Uncomments the current selection into compilation. Ctrl + K Ctrl + D Format Document Automatically formats the document into a structured layout. Lines up nodes or code into columns intelligently. Alt + ? Alt + ? Code line up/down *Use this combo to move a line of code up or down quickly. Great for small rearrangements of code. *Requires the Productivity Power pack from Microsoft. Conclusion This list is by no means meant to be exhaustive, but these are the shortcuts I use regularly every hour/minute of the day. There are still 100s more in Visual Studio that you can discover through the configuration window, or by tooltips. Something that I started doing months ago seems to have interest in my office.. In my last post, I talked about how I hated a cluttered UI. One of the ways that I aimed to resolve that was by systematically cleaning up the toolbars week by week. First day, I removed ALL icons that I already knew shortcuts to, or would never use them (Undo in a toolbar?!). Then, every week from that point on, I make it a point to remove an icon/two from the toolbar and make an effort to remember its key combination. I gain extra space in the toolbar area, AND become more productive at the same time! I hope that you found this article interesting or at least somewhat informative.. Maybe a shortcut or two you didn't know. I know some of them seem trivial, but I often see people going to the edit menu for Copy/Paste... Thought a refresher might be helpful!

  • Pygame Tile Based Character movement speed

    - by Ryan
    Thanks for taking the time to read this. Right now I'm making a really basic tile based game. The map is a large amount of 16x16 tiles, and the character image is 16x16 as well. My character has its own class that is an extension of the sprite class, and the x and y position is saved in terms of the tile position. To note I am fairly new to pygame. My question is, I am planning to have character movement restricted to one tile at a time, and I'm not sure how to make it so that, even if the player hits the directional key dozens of time quickly, (WASD or arrow keys) it will only move from tile to tile at a certain speed. How could I implement this generally with pygame? (Similar to game movement of like Pokemon or NexusTk). Edit: I should probably note that I want it so that the player can only end a movement in a tile. He couldn't stop moving halfway inbetween a tile for example. Thanks for your time! Ryan

  • emca fails with "Database instance is unavailable" though available

    - by Giri Mandalika
    The following example shows the symptoms of failure, and the exact error message. $ emca -repos create ... Password for SYSMAN user: Do you wish to continue? [yes(Y)/no(N)]: Y Nov 19, 2012 10:33:42 AM oracle.sysman.emcp.DatabaseChecks \ checkDbAvailabilityImpl WARNING: ORA-01034: ORACLE not available Nov 19, 2012 10:33:42 AM oracle.sysman.emcp.DatabaseChecks \ throwDBUnavailableException SEVERE: Database instance is unavailable. Fix the ORA error thrown and run EM Configuration Assistant again. Some of the possible reasons may be : 1) Database may not be up. 2) Database is started setting environment variable ORACLE_HOME with trailing '/'. Reset ORACLE_HOME and bounce the database. For eg. Database is started setting environment variable ORACLE_HOME=/scratch/db/ . Reset ORACLE_HOME=/scratch/db and bounce the database. Fix: Ensure that the ORACLE_HOME is pointing to the right location in $ORACLE_HOME/bin/emca file. Rather than installing from scratch, if ORACLE_HOME was copied over from another location, likely it results in wrong location for ORACLE_HOME in several Enterprise Manager (EM) specific scripts and files. It usually happens when the directory structure on the target machine is not identical to the structure on the original/source machine, including the top level directory location where Oracle RDBMS was installed properly using the installer.

  • IASA South East Florida Chapter February Meeting Report

    - by Rainer Habermann
    IASA South East Florida Chapter – February Meeting The topic for our February chapter meeting was Legal Issues in IT. Ms. Kennedy, Intellectual Property Attorney with an active litigation, trademark and copyright practice, presented: How Google, Wal-Mart & Apple Make their Millions – The Secret Ingredient: Intellectual Property This topic initiated great interest and the meeting room at Microsoft Ft. Lauderdale filled up to the last seat. Most Architects, Engineers, and MBA’s are not aware about Intellectual Property, Basic Patent, Trademark, or legal issues related to the web. After clarifying the basic definitions, Ms. Kennedy explained in detail how intellectual property issues could make or break a company. Members had the opportunity at the end of the presentation to ask questions, discuss legal problems, and several members shared their experiences related to Intellectual Property and other IT related issues. If you want to protect your ideas and intellectual property, you have to be aware of the implications and need to take the right steps in order to protect them. All Chapter Members agreed that it was an outstanding and lively presentation. Ms. Kennedy presented high quality content and made participants aware of legal IT issues. In the name of all chapter members, thank you Ms. Kennedy for taking the time for this amazing presentation and to Quent Herschelman for hosting the meeting.

    The "Quick Watch" feature of Visual Studio is an awesome tool when debugging your stuff...  I use it all the time and quite often I end up exploring hashtables or lists of all sorts...  One thing I hate is when I have to explore Collections...  Good god did I lose time trying to find the inner member that contains my stuff when exploring collections...  Most collections have the inside member that you can search for and find and explore to see the list of things you wanted to look at.  Something in the likes of this.    I've known a little trick for a while now and I give it to everyone I end up debugging something with so I figured that probably not many people know about this...  Here's the tip...  Send the collection into an ArrayList in the QuickWatch window!  Yes, you heard me right, just type    new ArrayList(yourcollectionhere) in my case:    new ArrayList(this.Controls) in the expresion textbox and here's the result when you hit reevaluate! Pretty neat trick to make your debugging experience less of a pain when dealing with collections...    Happy debugging all !

  • Does the use of mongodb it easier to extend/change database driven applications?

    - by developer10214
    When an application is created which need to store data, an SQL database is used very often. So did I in a lot of asp.net applications. The resulting applications have often an ORM like the entity framework and maybe a business layer. So when such an application needs to be extended(let's say you have to add a comment property to an object), you have to change/extend the database, then the ORM and the business layer and so on. To deploy the changes you have to update the target database and the application. I know that things like code first and fluent can make this approach easier. I tried mongodb, I only used the standard driver and I had to extend some objects and all I had to do was changing the code. So it feels that such approaches are much easier to realize when using mongodb. I don't have much experience with larger applications an mongodb. I know that a SQL database or mongodb doesn't fit for all needs and both have their pros and cons. I want to know if my feeling is right, if yes I would choose rather choose mongodb than SQL database.

  • Formatting HTML lists using CSS

    - by pwaring
    I'm trying to recreate list in HTML which has clauses and subclauses like this: 1. Main Clause (a) Sub clause (b) Sub clause 2. Another main clause (a) Sub clause The problems I'm running into are: If I use the existing HTML elements (ol and li) there doesn't seem to be a list style for (a) - I can have a. b. c. or A. B. C. but not (a) (b) (c). If I don't use the existing HTML elements and start using span tags, then if a subclause runs beyond the end of the line it appears underneath the clause number, rather than being indented. Like so: (a) Very long subclause which goes over one line when what I really want is the behaviour from lists, which is: (a) Very long subclause which goes over one line Is there any way to get round these two problems at the same time? I'd prefer to use semantic HTML and CSS for styling, but having the clauses spaced correctly is more important than doing things 'the right way'. I may need subsubclauses at some point (i.e. (i), (ii) etc.), so I can't assume that (a) will be the maximum clause depth.

  • Morph a sphere to a cube and a cube to a sphere with GLSL

    - by nkint
    I'm getting started with GLSL with quartz composer. I have a patch with a particle system in which each particle is mapped into a sphere with a blend value. With blend=0 particles are in random positions, blend=1 particles are in the sphere. The code is here: vec3 sphere(vec2 domain) { vec3 range; range.x = radius * cos(domain.y) * sin(domain.x); range.y = radius * sin(domain.y) * sin(domain.x); range.z = radius * cos(domain.x); return range; } // in main: vec2 p0 = gl_Vertex.xy * twopi; vec3 normal = sphere(p0);; vec3 r0 = radius * normal; vec3 vertex = r0; normal = normal * blend + gl_Normal * (1.0 - blend); vertex = vertex * blend + gl_Vertex.xyz * (1.0 - blend); I'd like the particle to be on a cube if blend=0 I've tried to find but I can't figure out some parametric equation for the cube. Maybe it is not the right way?

  • Understanding HTTP Cookies in Indy 10 for Delphi XE2

    - by Jerry Dodge
    I have been working with Indy 10 HTTP Servers / Clients lately in Delphi XE2, and I need to make sure I'm understanding session management correctly. In the server, I have a "bucket" of sessions, which is a list of objects which each represent a unique session. I don't use username and password to authenticate users, but I rather use a unique API key which is issued to a client, and has an expiration. When a client wishes to connect to the server, it first logs in by calling the "login" command, which is a path like this: http://localhost:1234/login?APIKey=abcdefghij. The server checks this API Key against the database, and if it's valid, it creates a new session in the bucket, issues a new cookie (unique string), and sets the response cookies with Success=Y and Cookie=abcdefghij. This is where I have the question. Assuming the client end has its own method of cookie management, the client will receive this login response back from the server and automatically save the cookies as necessary. Any future request from the client to the server shall automatically send along these cookies, and the client side doesn't have to necessarily worry about setting these cookies when sending requests to the server. Right? PS - I'm asking this question here on programmers.stackexchange.com because I didn't see it fit to ask on stackoverflow.com. If anyone thinks this is appropriate enough for stackoverflow.com, please let me know.

  • How to Add the Windows Calculator to the Quick Access Toolbar in Microsoft Excel 2013

    - by Lori Kaufman
    Do you use the Windows Calculator to perform quick calculations while building spreadsheets in Excel? You can save time by adding the Calculator to the Quick Access Toolbar in Excel so you don’t have to leave the program to access the Calculator. To do this, click the down arrow on the right side of the Quick Access Toolbar and select More Commands from the drop-down menu. On the Quick Access Toolbar screen on the Excel Options dialog box, select Commands Not in the Ribbon from the Choose commands from drop-down list. Scroll down in the long list and select Calculator. Click Add to add the Calculator to the Quick Access Toolbar. Click OK to accept the change and close the Excel Options dialog box. You’ll see a Calculator icon on the Quick Access Toolbar. When you move your mouse over the icon, a hint displays saying “Custom.” Despite the label, when you click the icon, the Windows Calculator opens. The same procedure works for adding the Windows Calculator to Excel 2010, as well.

  • /planes and /clubs or /wiki/planes and /wiki/clubs

    - by Jelmer
    I am currently working on a nice application about which I can't share all the details, but it will have some sort of a wiki part. In this wiki, you will be able to change the planes as well as the clubs, maybe in the future it will be possible to change the countries and manufacturers as well. But I have to think about this and I have to check how good this is. But, you will understand that it has to be expendable! That is really important. Use the planes controller with a edit page and the same for the clubs Route the planes and clubs controller to the wiki controller, so we have 1 nice "path" to edit this stuff. I want to have it called wiki that is for sure. Because that is what it is, but I am storing the planes and clubs data in its down table in my database. I think that is kinda obvious since it has to be maintainable. Right now you could edit a plane via the url: example.com/wiki/planes/edit/Duo_Discus.html Do you think that is better than example.com/planes/edit/Duo_Discus.html since it is easy to understand for the user, that he is working in the wiki instead of in the planes ? Or do you think this will break the user experience?

  • SQL Developer: Describe versus Ctrl+Click to Open Database Objects

    - by thatjeffsmith
    In yesterday’s post I talked about you could use SQL Developer’s Describe (SHIFT+F4) to open a PL/SQL Package at your cursor. You might get an error if you try to describe this… If you actually try to describe the package as you see it in the above screenshot, you’ll get an error: Doh! I neglected to say in yesterday’s post that I was highlighting the package name before I hit SHIFT+F4. This works just fine, but it will work even better in our next release as we’ve fixed this issue. Until then, you can also try the Ctrl+Hover with your mouse. For PL/SQL calls you can open the source immediately based on what you’re hovering over with your mouse cursor. You could try this with “dbms_output.put_line(” too Ctrl+Click, It’s not just for PL/SQL If you don’t like the floating describe windows you get when you do a SHIFT+F4 on a database object, the ctrl+click will work too. Instead of opening a normal ‘hover’ panel, you’ll be taken directly to the object editor for that table, view, etc. Go ahead and try it right now. Paste this into your worksheet, then ctrl+click with your mouse over the table name: select * from scott.emp And now you know, the rest of the story.
