• Introducing MySQL for Excel

  - by Javier Treviño

  As part of the new product initiatives of the MySQL on Windows group we released a tool that makes the task of getting data in and out of a MySQL Database very friendly and intuitive, and we paired it with one of the preferred applications for data analysis and manipulation in Windows platforms, MS Excel. Welcome to MySQL for Excel, an add-in that is installed and accessed from within the MS Excel’s Data tab offering a wizard-like interface arranged in an elegant yet simple way to help users browse MySQL Schemas, Tables, Views and Procedures and perform data operations against them using MS Excel as the vehicle to drive the data in and out MySQL Databases. One of the coolest features we had in mind designing MySQL for Excel is simplicity. MS Excel is simple and easy to work with, thus liked by many Windows users because they don’t have to be software gurus to use it.  We applied the same principle by targeting MySQL for Excel to any kind of user, so if you are already familiarized with Excel’s interface you will find yourself working with MySQL data in no time. MySQL for Excel is shipped within the MySQL Installer as one of the tools in the suite; if prerequisites are already installed (.NET Framework 4.0, Visual Studio Tools for Office 4.0 and of course MS Office), installing the add-in involves a very few clicks and no further setup to use it. Being an Excel Add-In there is no executable file involved after the installation, running MS Excel and opening the add-in from its Data tab is all that is required. MySQL for Excel automatically integrates with MySQL Workbench (if installed) to share the same connections to MySQL Server installations, that way connections are defined just once in either product saving time.  Opening the Add-In brings the Welcome Panel at the right side of the Excel main window from which connections to MySQL Servers are shown grouped by Local VS Remote connections; then users can open any of those connections by double-clicking it and entering the password of the used account.  Additionally a user can create a connection by clicking on the New Connection action label or edit connections through MySQL Workbench (if installed) by clicking on the Manage Connections action label. Once a connection is opened, the Schema Selection panel is shown, at the top of it the selected connection (connection name, hostname/IP and username). Just below, a list of schemas is displayed where User Schemas are grouped first followed by System Schemas; users can double-click any selected schema to go to the next panel or select a schema and clicking the Next > button. Users can alternatively click on the < Back button to go back to the Welcome Panel to close the current connection and open a new one; also by clicking the Create New Schema action label they can create an empty new schema. Once a schema is opened the DB Object Selection panel is shown, this is actually the place where the fun stuff happens; from here users are able to perform actions against MySQL Tables, Views and Procedures. ">The actions available here are about importing data from a MySQL Table, View or Procedure to Excel, exporting Excel data to a new MySQL Table, appending Excel data to an existing MySQL Table or editing a MySQL Table’s data by using an Excel Worksheet as a user interface to update data in any row/column, insert new rows or delete existing rows in a very easy and friendly way. More blog posts will follow describing all of these actions, so stay tuned! Remember that your feedback is very important for us, so drop us a message: · MySQL on Windows (this) Blog - https://blogs.oracle.com/MySqlOnWindows/ · Forum - http://forums.mysql.com/list.php?172 · Facebook - http://www.facebook.com/mysql Cheers!

• How to Use Sparklines in Excel 2010

  - by DigitalGeekery

  One of the cool features of Excel 2010 is the addition of Sparklines. A Sparkline is basically a little chart displayed in a cell representing your selected data set that allows you to quickly and easily spot trends at a glance. Inserting Sparklines on your Spreadsheet You will find the Sparklines group located on the Insert tab.   Select the cell or cells where you wish to display your Sparklines. Select the type of Sparkline you’d like to add to your spreadsheet. You’ll notice there are three types of Sparklines, Line, Column, and Win/Loss. We’ll select Line for our example. A Create Sparklines pops up and will prompt you to enter a Data Range you are using to create the Sparklines. You’ll notice that the location range (the range where the Sparklines will appear) is already filled in. You can type in the data range manually, or click and drag with your mouse across to select the data range. This will auto-fill the data range for you. Click OK when you are finished.   You will see your Sparklines appear in the desired cells.   Customizing Sparklines Select the one of more of the Sparklines to reveal the Design tab. You can display certain value points like high and low points, negative points, and first and last points by selecting the corresponding options from the Show group. You can also mark all value points by selecting  Markers. Select your desired Sparklines and click one of the included styles from the Style group on the Design tab. Click the down arrow on the lower right corner of the box to display additional pre-defined styles…   or select Sparkline Color or Marker Color options to fully customize your Sparklines. The Axis options allow additional options such as Date Axis Type, Plotting Data Left to Right, and displaying an axis point to represent the zero line in your data with Show Axis. Column Sparklines Column Sparklines display your data in individual columns as opposed to the Line view we’ve been using for our examples. Win/Loss Sparklines Win/Loss shows a basic positive or negative representation of your data set.   You can easily switch between different Sparkline types by simply selecting the current cells (individually or the entire group), and then clicking the desired type on the Design tab. For those that may be more visually oriented, Sparklines can be a wonderful addition to any spreadsheet. Are you just getting started with Office 2010?

• Adding Output Caching and Expire Header in IIS7 to improve performance

  - by Renso

  The problem: Images and other static files will not be cached unless you tell it to. In IIS7 it is remarkably easy to do this. Web pages are becoming increasingly complex with more scripts, style sheets, images, and Flash on them. A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts, style sheets, and Flash. Every time a page is loaded, every image and other static content like JavaScript files and CSS files will be reloaded on every page request. If the content does not change frequently why not cache it and avoid the network traffic?! The solution: In IIS7 there are two ways to cache content, using the web.config file to set caching for all static content, and in IIS7 itself setting aching by file extension that gives you that extra level of granularity. Web.config: In IIS7, Expires Headers can be enabled in the system.webServer section of the web.config file:   <staticContent>     <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />   </staticContent> In the above example a cache expiration of 1 day was added. It will be a full day before the content is downloaded from the web server again. To expire the content on a specific date:   <staticContent>     <clientCache cacheControlMode="UseExpires" httpExpires="Sun, 31 Dec 2011 23:59:59 UTC" />   </staticContent> This will expire the content on December 31st 2011 one second before midnight. Issues/Challenges: Once the file has been set to be cached it wont be updated on the user's browser for the set cache expiration. So be careful here with content that may change frequently, like during development. Typically in development you don't want to cache at all for testing purposes. You could also suffix files with timestamp or versions to force a reload into the user's browser cache. IIS7 Expire Web Content Open up your web app in IIS. Open up the sub-folders until you find the folder or file you want to ad an expiration date to. In IIS6 you used to right-click and select properties, no such luck in IIS7, double click HTTP Response. Once the window loads for the HTTP Response Headers, look to the Actions navigation bar to the right, all the way at the top select SET COMMON HEADERS. The Enable HTTP keep-alive will already be pre-selected. Go ahead and add the appropriate expiration header to the file or folder. Note that if you selected a folder, it will apply that setting to all images inside that folder and all nested content, even subfolders. So, two approaches, depending on what level or granularity you need.

• Change The Windows 7 Start Orb the Easy Way

  - by Matthew Guay

  Want to make your Windows 7 PC even more unique and personalized?  Then check out this easy guide on how to change your start orb in Windows 7. Getting Started First, download the free Windows 7 Start Button Changer (link below), and extract the contents of the folder.  It contains the app along with a selection of alternate start button orbs you can try out.   Before changing the start button, we advise creating a system restore point in case anything goes wrong.  Enter System Restore in your Start menu search, and select “Create a restore point”. Please note:  We tested this on both the 32 bit and 64 bit editions of Windows 7, and didn’t encounter any problems or stability issues.  That said, it is always prudent to make a restore point just in case a problem did happen. Click the Create button… Then enter a name for the restore point, and click Create. Changing the Start Orb. Once this is finished, run the Windows 7 Start Button Changer as administrator by right-clicking on it and selecting “Run as administrator”.  Accept the UAC prompt that will appear. If you don’t run it as an administrator, you may see the following warning.  Click Quit, and then run again as administrator. You should now see the Windows 7 Start Button Changer.  On the left it shows what your current (default) start orb looks like inactive, when hovered over, and when selected.  Click the orb on the right to select a new start button. Here we browsed to the sample orbs folder, and selected one of them.  Let’s give Windows the Media Center orb for a start orb.  Click the orb you want, and then select open. When you click Open, your screen will momentarily freeze and your taskbar will disappear.  When it reappears, your computer will have gone from having the old, default Start orb style… …to your new, exciting Start orb!  Here it is default, and glowing when hovered over. Now, the Windows 7 Start Orb Changer will change, and show your new Start orb on the left side.  If you would like to revert to the default orb, simply click the folder icon to restore it.  Or, if you would like to change the orb again, restore the original first and then select a new one. The orbs don’t have to be round; here’s a fancy Windows 7 logo as the start button. The start orb change will work in the Aero and Aero basic (which Windows 7 Start uses) themes, but will not show up in the classic, Windows 2000 style themes.  Here’s how the new start button looks with the Aero Classic theme: There are tons of orbs available, including this cute smiley, so choose one that you like to make your computer uniquely yours. Conclusion This is a cute way to make your desktop unique, and can be a great way to make a truly personalized theme.  Let us know your favorite Start orb!

• SQL SERVER – How to Roll Back SQL Server Database Changes

  - by Pinal Dave

  In a perfect scenario, no unexpected and unplanned changes occur. There are no unpleasant surprises, no inadvertent changes. However, even with all precautions and testing, there is sometimes a need to revert a structure or data change. One of the methods that can be used in this situation is to use an older database backup that has the records or database object structure you want to revert to. For this method, you have to have the adequate full database backup and a tool that will help you with comparison and synchronization is preferred. In this article, we will focus on another method: rolling back the changes. This can be done by using: An option in SQL Server Management Studio T-SQL, or ApexSQL Log The first two solutions have been described in this article The disadvantages of these methods are that you have to know when exactly the change you want to revert happened and that all transactions on the database executed in a specific time range are rolled back – the ones you want to undo and the ones you don’t. How to easily roll back SQL Server database changes using ApexSQL Log? The biggest challenge is to roll back just specific changes, not all changes that happened in a specific time range. While SQL Server Management Studio option and T-SQL read and roll forward all transactions in the transaction log files, I will show you a solution that finds and scripts only the specific changes that match your criteria. Therefore, you don’t need to worry about all other database changes that you don’t want to roll back. ApexSQL Log is a SQL Server disaster recovery tool that reads transaction logs and provides a wide range of filters that enable you to easily rollback only specific data changes. First, connect to the online database where you want to roll back the changes. Once you select the database, ApexSQL Log will show its recovery model. Note that changes can be rolled back even for a database in the Simple recovery model, when no database and transaction log backups are available. However, ApexSQL Log achieves best results when the database is in the Full recovery model and you have a chain of subsequent transaction log backups, back to the moment when the change occurred. In this example, we will use only the online transaction log. In the next step, use filters to read only the transactions that happened in a specific time range. To remove noise, it’s recommended to use as many filters as possible. Besides filtering by the time of the transaction, ApexSQL Log can filter by the operation type: Table name: As well as transaction state (committed, aborted, running, and unknown), name of the user who committed the change, specific field values, server process IDs, and transaction description. You can select only the tables affected by the changes you want to roll back. However, if you’re not certain which tables were affected, you can leave them all selected and once the results are shown in the main grid, analyze them to find the ones you to roll back. When you set the filters, you can select how to present the results. ApexSQL Log can automatically create undo or redo scripts, export the transactions into an XML, HTML, CSV, SQL, or SQL Bulk file, and create a batch file that you can use for unattended transaction log reading. In this example, I will open the results in the grid, as I want to analyze them before rolling back the transactions. The results contain information about the transaction, as well as who and when made it. For UPDATEs, ApexSQL Log shows both old and new values, so you can easily see what has happened. To create an UNDO script that rolls back the changes, select the transactions you want to roll back and click Create undo script in the menu. For the DELETE statement selected in the screenshot above, the undo script is: INSERT INTO [Sales].[PersonCreditCard] ([BusinessEntityID], [CreditCardID], [ModifiedDate]) VALUES (297, 8010, '20050901 00:00:00.000') When it comes to rolling back database changes, ApexSQL Log has a big advantage, as it rolls back only specific transactions, while leaving all other transactions that occurred at the same time range intact. That makes ApexSQL Log a good solution for rolling back inadvertent data and schema changes on your SQL Server databases.

• Using the Script Component as a Conditional Split

  This is a quick walk through on how you can use the Script Component to perform Conditional Split like behaviour, splitting your data across multiple outputs. We will use C# code to decide what does flows to which output, rather than the expression syntax of the Conditional Split transformation. Start by setting up the source. For my example the source is a list of SQL objects from sys.objects, just a quick way to get some data: SELECT type, name FROM sys.objects type name S syssoftobjrefs F FK_Message_Page U Conference IT queue_messages_23007163 Shown above is a small sample of the data you could expect to see. Once you have setup your source, add the Script Component, selecting Transformation when prompted for the type, and connect it up to the source. Now open the component, but don’t dive into the script just yet. First we need to select some columns. Select the Input Columns page and then select the columns we want to uses as part of our filter logic. You don’t need to choose columns that you may want later, this is just the columns used in the script itself. Next we need to add our outputs. Select the Inputs and Outputs page.You get one by default, but we need to add some more, it wouldn’t be much of a split otherwise. For this example we’ll add just one more. Click the Add Output button, and you’ll see a new output is added. Now we need to set some properties, so make sure our new Output 1 is selected. In the properties grid change the SynchronousInputID property to be our input Input 0, and  change the ExclusionGroup property to 1. Now select Ouput 0 and change the ExclusionGroup property to 2. This value itself isn’t important, provided each output has a different value other than zero. By setting this property on both outputs it allows us to split the data down one or the other, making each exclusive. If we left it to 0, that output would get all the rows. It can be a useful feature allowing you to copy selected rows to one output whilst retraining the full set of data in the other. Now we can go back to the Script page and start writing some code. For the example we will do a very simple test, if the value of the type column is U, for user table, then it goes down the first output, otherwise it ends up in the other. This mimics the exclusive behaviour of the conditional split transformation. public override void Input0_ProcessInputRow(Input0Buffer Row) { // Filter all user tables to the first output, // the remaining objects down the other if (Row.type.Trim() == "U") { Row.DirectRowToOutput0(); } else { Row.DirectRowToOutput1(); } } The code itself is very simple, a basic if clause that determines which of the DirectRowToOutput methods we call, there is one for each output. Of course you could write a lot more code to implement some very complex logic, but the final direction is still just a method call. If we now close the script component, we can hook up the outputs and test the package. Your numbers will vary depending on the sample database but as you can see we have clearly split out input data into two outputs. As a final tip, when adding the outputs I would normally rename them, changing the Name in the Properties grid. This means the generated methods follow the pattern as do the path label shown on the design surface, making everything that much easier to recognise.

• SQL Script to Assign All Items to ALL Sites with Dynamics GP

mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} When setting up new items within Microsoft Dynamics GP, you will often run into the error message below which reads “This site is not assigned to the selected item.  Do you want to assign this site?”  The fix is quite simple given that you simply click the Add button below which opens up the Item Quantities Maintenance window which you will hit the save button and proceed with the entry of your Sales Order or Purchase Order.   If you have a lot of new items into GP and have just one Site ID setup, the best approach to assigning your items to a particular site is by going to the Site Maintenance Window which is located in Cards>>Inventory>>Site.  Once you are in the window below, you can click the Assign button to assign Items to the Site selected.     However, if you have you a lot of Sites and Items created, this can be quite a cumbersome and time consuming process.  For that, I have created the following SQL Script below that Assigns all Items to all Site ID’s within Microsoft Dynamics GP 2010.    declare @item varchar(100)       , @loc varchar(100)       , @ItemExist int         DECLARE

• How do I revert updates/tweaks to get to a usable GUI?

  - by Frankenmartin

  I just installed 12.04 the other day and then ran into trouble upon restarting after installing updates. What I did before the problem occurred: I did not make many changes before this problem occurred. Changes I did make included: Downloading and installing Adobe Flash Player (off topic but: I am under the impression that Java, "C&C" and Shockwave can not be run in Ubuntu. Could anybody verify this?) I also installed gnome-tweak-tool and used it to install several themes. These themes worked well until restarting after the update. Is it possible that one of these themes caused the problem (in combination with the update or because of the restart)? Installed 215 updates from update manager and restarted my system. Current Situation: Unity 3D is unusable since restarting after running updates. When I log in after entering my password the following things happen: the overhead panel disappears and the screen goes black for a minute my wallpaper flashes for a couple seconds but then the screen goes black again after another minute the wallpaper reappears but nothing else does and I am not able to open anything or even right click. after 5 minutes I can finally get a right click menu eventually a box comes up warning about a Compiz failure and asking to let it quit--which I did. Using the right click functionality I was able to create a new folder on the desktop and use this to open a file browser. In doing so I noticed that the downloads I had made were missing (music, image files, etc., even after unpacking several .zip and .rar files) even though I believe that everything should still be there. Any new windows that I create are un-closable/minimizable/movable/etc, because the window bars are missing. I have tried rebooting several times but the results are the same. I was able to browse some off the System Settings windows by clicking on the wallpaper link in the right click menu. In doing so I navigated into the update manager and noticed that updates were selected to be accepted from some "unsupported sources". I do not recall setting these options myself and wonder why these--potentially dangerous--options would be selected by default. Unity 2D is usable but not free of bugs--I stumbled across the ability to log into a Unity 2D session while trying to log into Unity 3D. So far I have only noticed one bug in Unity 2D: the close, minimize and maximize buttons are invisible--however they are still usable despite being invisible. What I need: I'm very new to Linux and Ubuntu and still am in the feeling out stages. As such I will have some trouble answering clarifying questions. I haven't used the terminal yet and would probably not be comfortable using it without very clear instructions. What I do need is to know how I can roll back/remove all those updates so I can use my computer regularly again. I do believe that I could follow step-by-step instructions as long as they are clear and concise if someone knows what my problem is.

• Improving Click and Drag with C++

  - by Josh

  I'm currently using SFML 2.0 to develop a game in C++. I have a game sprite class that has a click and drag method. The method works, but there is a slight problem. If the mouse moves too fast, the object the user selected can't keep up and is left behind in the spot where the mouse left its bounds. I will share the class definition and the given function implementation. Definition: class codePeg { protected: FloatRect bounds; CircleShape circle; int xPos, yPos, xDiff, yDiff, once; int xBase, yBase; Vector2i mousePos; Vector2f circlePos; public: void init(RenderWindow& Window); void draw(RenderWindow& Window); void drag(RenderWindow& Window); void setPegPosition(int x, int y); void setPegColor(Color pegColor); void mouseOver(RenderWindow& Window); friend int isPegSelected(void); }; Implementation of the "drag" function: void codePeg::drag(RenderWindow& Window) { mousePos = Mouse::getPosition(Window); circlePos = circle.getPosition(); if(Mouse::isButtonPressed(Mouse::Left)) { if(mousePos.x > xPos && mousePos.y > yPos && mousePos.x - bounds.width < xPos && mousePos.y - bounds.height < yPos) { if(once) { xDiff = mousePos.x - circlePos.x; yDiff = mousePos.y - circlePos.y; once = 0; } xPos = mousePos.x - xDiff; yPos = mousePos.y - yDiff; circle.setPosition(xPos, yPos); } } else { once = 1; xPos = xBase; yPos = yBase; xDiff = 0; yDiff = 0; circle.setPosition(xBase, yBase); } Window.draw(circle); } Like I said, the function works, but to me, the code is very ugly and I think it could be improved and could be more efficient. The only thing I can think of as to why the object cannot keep up with the mouse is that there are too many function calls and/or checks. The user does not really have to mouse the mouse "fast" for it to happen, I would say at an average pace the object is left behind. How can I improve the code so that the object remains with the mouse when it is selected? Any help improving this code or giving advice is greatly appreciated.

• Access Control Service: Transitioning between Active and Passive Scenarios

  - by Your DisplayName here!

  As I mentioned in my last post, ACS features a number of ways to transition between protocol and token types. One not so widely known transition is between passive sign ins (browser) and active service consumers. Let’s see how this works. We all know the usual WS-Federation handshake via passive redirect. But ACS also allows driving the sign in process yourself via specially crafted WS-Federation query strings. So you can use the following URL to sign in using LiveID via ACS. ACS will then redirect back to the registered reply URL in your application: GET /login.srf?   wa=wsignin1.0&   wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&   wreply=https%3a%2f%2fleastprivilege.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&   wp=MBI_FED_SSL&   wctx=pr%3dwsfederation%26rm%3dhttps%253a%252f%252froadie%252facs2rp%252frest%252f The wsfederation bit in the wctx parameter indicates, that the response to the token request will be transmitted back to the relying party via a POST. So far so good – but how can an active client receive that token now? ACS knows an alternative way to send the token request response. Instead of doing the redirect back to the RP, it emits a page that in turn echoes the token response using JavaScript’s window.external.notify. The URL would look like this: GET /login.srf?   wa=wsignin1.0&   wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&   wreply=https%3a%2f%2fleastprivilege.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&   wp=MBI_FED_SSL&   wctx=pr%3djavascriptnotify%26rm%3dhttps%253a%252f%252froadie%252facs2rp%252frest%252f ACS would then render a page that contains the following script block: <script type="text/javascript">     try{         window.external.Notify('token_response');     }     catch(err){         alert("Error ACS50021: windows.external.Notify is not registered.");     } </script> Whereas token_response is a JSON encoded string with the following format: {   "appliesTo":"...",   "context":null,   "created":123,   "expires":123,   "securityToken":"...",   "tokenType":"..." } OK – so how does this all come together now? As an active client (Silverlight, WPF, WP7, WinForms etc). application, you would host a browser control and use the above URL to trigger the right series of redirects. All the browser controls support one way or the other to register a callback whenever the window.external.notify function is called. This way you get the JSON string from ACS back into the hosting application – and voila you have the security token. When you selected the SWT token format in ACS – you can use that token e.g. for REST services. When you have selected SAML, you can use the token e.g. for SOAP services. In the next post I will show how to retrieve these URLs from ACS and a practical example using WPF.

• SO-Aware Service Explorer – Configure and Export your services from VS 2010 into the repository

  - by cibrax

  We have introduced a new Visual Studio tool called “Service Explorer” as part of the new SO-Aware SDK version 1.3 to help developers to configure and export any regular WCF service into the SO-Aware service repository. This new tool is a regular Visual Studio Tool Window that can be opened from “View –> Other Windows –> Services Explorer”. Once you open the Services Explorer, you will able to see all the available WCF services in the Visual Studio Solution. In the image above, you can see that a “HelloWorld” service was found in the solution and listed under the Tool window on the left. There are two things you can do for a new service in tool, you can either export it to SO-Aware repository or associate it to an existing service version in the repository. Exporting the service to SO-Aware means that you want to create a new service version in the repository and associate the WCF service WSDL to that version. Associating the service means that you want to use a version already created in SO-Aware with the only purpose of managing and centralizing the service configuration in SO-Aware. The option for exporting a service will popup a dialog like the one bellow in which you can enter some basic information about the service version you want to create and the repository location. The option for associating a service will popup a dialog in which you can pick any existing service version repository and the application configuration file that you want to keep in sync for the service configuration. Two options are available for configuring a service, WCF Configuration or SO-Aware. The WCF Configuration option just tells the tool that the service will use the standard WCF configuration section “system.serviceModel” but that section must be updated and kept in sync with the configuration selected for the service in the repository. The SO-Aware configuration option will tell the tool that the service configuration will be resolved at runtime from the repository. For example, selecting SO-Aware will generate the following configuration in the selected application configuration file, <configuration> <configSections> <section name="serviceRepository" type="Tellago.ServiceModel.Governance.ServiceConfiguration.ServiceRepositoryConfigurationSection, Tellago.ServiceModel.Governance.ServiceConfiguration" /> </configSections> <serviceRepository url="http://localhost/soaware/servicerepository.svc"> <services> <service name="ref:HelloWorldService(1.0)@dev" type="SOAwareSampleService.HelloWorldService" /> </services> </serviceRepository> </configuration> As you can see the tool represents a great addition to the toolset that any developer can use to manage and centralize configuration for WCF services. In addition, it can be combined with other useful tools like WSCF.Blue (Web Service Contract First) for generating the service artifacts like schemas, service code or the service WSDL itself.

• Call For Papers Tips and Tricks

  - by speakjava

  This year's JavaOne session review has just been completed and by now everyone who submitted papers should know whether they were successful or not.  I had the pleasure again this year of leading the review of the 'JavaFX and Rich User Experiences' track.  I thought it would be useful to write up a few comments to help people in future when submitting session proposals, not just for JavaOne, but for any of the many developer conferences that run around the world throughout the year.  This also draws on conversations I recently had with various Java User Group leaders at the Oracle User Group summit in Riga.  Many of these leaders run some of the biggest and most successful Java conferences in Europe. Try to think of a title which will sound interesting.  For example, "Experiences of performance tuning embedded Java for an ARM architecture based single board computer" probably isn't going to get as much attention as "Do you like coffee with your dessert? Java on the Raspberry Pi".  When thinking of the subject and title for your talk try to steer clear of sessions that might be too generic (and so get lost in a group of similar sessions).  Introductory talks are great when the audience is new to a subject, but beware of providing sessions that are too basic when the technology has been around for a while and there are lots of tutorials already available on the web. JavaOne, like many other conferences has a number of fields that need to be filled in when submitting a paper.  Many of these are selected from pull-down lists (like which track the session is applicable to).  Check these lists carefully.  A number of sessions we had needed to be shuffled between tracks when it was thought that the one selected was not appropriate.  We didn't count this against any sessions, but it's always a good idea to try and get the right one from the start, just in case. JavaOne, again like many other conferences, has two fields that describe the session being submitted: abstract and summary.  These are the most critical to a successful submission.  The two fields have different names and that is significant; a frequent mistake people make is to write an abstract for a session and then duplicate it for the summary.  The abstract (at least in the case of JavaOne) is what gets printed in the show guide and is typically what will be used by attendees when deciding what sessions to attend.  This is where you need to sell your session, not just to the reviewers, but also the people who you want in your audience.  Submitting a one line abstract (unless it's a really good one line) is not usually enough to decide whether this is worth investing an hour of conference time.  The abstract typically has a limit of a few hundred characters.  Try to use as many of them as possible to get as much information about your session across.  The summary should be different from the abstract (and don't leave it blank as some people do).  This field is where you can give the reviewers more detail about things like the structure of the talk, possible demonstrations and so on.  As a reviewer I look to this section to help me decide whether the hard-sell of the title and abstract will actually be reflected in the final content.  Try to make this comprehensive, but don't make it excessively long.  When you have to review possibly hundreds of sessions a certain level of conciseness can make life easier for reviewers and help the cause of your session. If you've not made many submissions for talks in the past, or if this is your first, try to give reviewers places to find background on you as a presenter.  Having an active blog and Twitter handle can also help reviewers if they're not sure what your level of expertise is.  Many call-for-papers have places for you to include this type of information.  It's always good to have new and original presenters and presentations for conferences.  Hopefully these tips will help you be successful when you answer the next call-for-papers.

• The World of SQL Database Deployment

  - by GGBlogger

  In my early development days, I used Microsoft Access for building databases. It made things easy since I only needed to package the database with the installation package so my clients would have access to it. When we began the development of a new package in Visual Studio .NET I decided to use SQL Server Express. It was free and provided good tools - also free. I thought it was a tremendous idea until it came time to distribute our new software! What a surprise. The nightmare Ah, the choices! Detach the database and have the client reattach it to a newly installed – oh wait. FIRST my new client needs to download and install SQL Server Express with SQL Server Management Studio. That’s not a great thing, but it is one more nightmare step for users who may have other versions of SQL installed. Then the question became – do we detach and reattach or do we do a backup. It was too late (bad planning) to revert to Microsoft Access but we badly needed a simple way to package and distribute both the database AND sample contents. Red Gate to the rescue It took me a while to find an answer but I did find it in a package called SQL Packager sold by a relatively unpublicized company in England called Red Gate. They call their products “ingeniously simple” and I must agree with that description. With SQL Packager you point to the database (more in a minute) you want to distribute. A few mouse clicks and dialogs and you have an executable file that you can ship virtually anywhere and virtually any way which, when run, installs the database on your destination SQL Server instance! It really is that simple. Easier to show than tell Let’s explore a hypothetical case. Let’s say you have a local SQL database of customers and you have decided you want to share it with your subsidiaries or partners. Here is the underlying screen you will see on starting SQL Packager. There are a bunch of possibilities here but I’m going to keep this relatively simple. At this point I simply want to illustrate the simplicity of generating an executable to deliver your database. You will notice that you can set up a new package, edit an existing package or change a bunch of options. Start SQL packager And the following is the default dialog you get on startup. In the next dialog, I’ve selected the Server and Database. I’ve also selected Windows Authentication. Pressing Next causes SQL Packager to run a number of checks and produce a report. Now you’re given a comprehensive list of what is going to be packaged and you’re allowed to change it if you desire. I’ve never made any changes here so I can’t really make any suggestions. The just illustrates the comprehensive nature of so many Red Gate products including this one. Clicking Next gives you still further options. SQL Packager then works its magic and shows you a dialog with the results. Packager then gives you a dialog of the scripts it has generated. The capture above only shows 1 of 4 tabs. Finally pressing Next gives you the option to generate a .NET executable of a C# project. I’ve only generated an executable so I’m not in a position to tell you what the C# project looks like. That may be the subject of further discussions. You can rename the package and tell SQL Packager where to save it. I’ve skipped a lot but this will serve to illustrate the comprehensive (and ingenious) things Red Gate does. All in all, it’s a superb way to distribute populated SQL databases. Oh – we’ll save running the resulting executable for later also but believe me it’s insanely simple.

• Searching for context in Silverlight applications

  - by PeterTweed

  A common behavior in business applications that have developed through the ages is for a user to be able to get information or execute commands in relation to some information/function displayed by right clicking the object in question and popping up a context menu that offers relevant options to choose. The Silverlight Toolkit April 2010 release introduced the context menu object.  This can be added to other UI objects and display options for the user to choose.  The menu items can be enabled or disabled as per your application logic and icons can be added to the menu items to add visual effect.  This post will walk you through how to use the context menu object from the Silverlight Toolkit. Steps: 1. Create a new Silverlight 4 application 2. Copy the following namespace definition to the user control object of the MainPage.xaml file: xmlns:my="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit"   3. Copy the following XAML into the LayoutRoot grid in MainPage.xaml:          <Border CornerRadius="15" Background="Blue" Width="400" Height="100">             <TextBlock Foreground="White" FontSize="20" Text="Context Menu In This Border...." HorizontalAlignment="Center" VerticalAlignment="Center" >             </TextBlock>             <my:ContextMenuService.ContextMenu>                 <my:ContextMenu >                     <my:MenuItem                 Header="Copy"                 Click="CopyMenuItem_Click" Name="copyMenuItem">                         <my:MenuItem.Icon>                             <Image Source="copy-icon-small.png"/>                         </my:MenuItem.Icon>                     </my:MenuItem>                     <my:Separator/>                     <my:MenuItem Name="pasteMenuItem"                 Header="Paste"                 Click="PasteMenuItem_Click">                         <my:MenuItem.Icon>                             <Image Source="paste-icon-small.png"/>                         </my:MenuItem.Icon>                     </my:MenuItem>                 </my:ContextMenu>             </my:ContextMenuService.ContextMenu>         </Border>   The above code associates a context menu with two menu items and a separator between them to the border object.  The menu items has icons associated with them to add visual appeal.  The menu items have click event handlers that will be added in the MainPage.xaml.cs code behind in a later step. 4. Add two icon sized images to the ClientBin directory of the web project hosting the Silverlight application, named copy-icon-small.png and paste-icon-small.jpg respectively.  I used copy and paste icons as the names suggest. 5. Add the following code to the class in MainPage.xaml.cs file:         private void CopyMenuItem_Click(object sender, RoutedEventArgs e)         {             MessageBox.Show("Copy selected");         }           private void PasteMenuItem_Click(object sender, RoutedEventArgs e)         {             MessageBox.Show("Paste selected");         }   This code adds the event handlers for the menu items defined in step 3. 6. Run the application, right click on the border and select a menu option and see the appropriate message box displayed. Congratulations it’s that easy!   Take the Slalom Challenge at www.slalomchallenge.com!

• A* algorithm very slow

  - by Amaranth

  I have an programming a RTS game (I use XNA with C#). The pathfinding is working fine, except that when it has a lot of node to search in, there is a lag period of one or two seconds, it happens mainly when there is no path to the target destination, since it that situation there is more nodes to explore. I have the same problem when the path is shorter but selected more than 3 units (can't take the same path since the selected units can be in different part of the map). private List<NodeInfo> FindPath(Unit u, NodeInfo start, NodeInfo end) { Map map = GameInfo.GetInstance().GameMap; _nearestToTarget = start; start.MoveCost = 0; Vector2 endPosition = map.getTileByPos(end.X, end.Y).Position; //getTileByPos simply gets the tile in a 2D array with the X and Y indexes start.EstimatedRemainingCost = (int)(endPosition - map.getTileByPos(start.X, start.Y).Position).Length(); start.Parent = null; List<NodeInfo> openedNodes = new List<NodeInfo>(); ; List<NodeInfo> closedNodes = new List<NodeInfo>(); Point[] movements = GetMovements(u.UnitType); openedNodes.Add(start); while (!closedNodes.Contains(end) && openedNodes.Count > 0) { //Loop in nodes to find lowest cost NodeInfo currentNode = FindLowestCostOpenedNode(openedNodes); openedNodes.Remove(currentNode); closedNodes.Add(currentNode); Vector2 previousMouvement; if (currentNode.Parent == null) { previousMouvement = ConvertRotationToDirectionVector(u.Rotation); } else { previousMouvement = map.getTileByPos(currentNode.X, currentNode.Y).Position - map.getTileByPos(currentNode.Parent.X, currentNode.Parent.Y).Position; previousMouvement.Normalize(); } //For each neighbor foreach (Point movement in movements) { Point exploredGridPos = new Point(currentNode.X + movement.X, currentNode.Y + movement.Y); //Checks if valid move and checks if not if closed nodes list if (ValidNavigableNode(u.UnitType, new Point(currentNode.X, currentNode.Y), exploredGridPos) && !closedNodes.Contains(_gridMap[exploredGridPos.Y, exploredGridPos.X])) { NodeInfo exploredNode = _gridMap[exploredGridPos.Y, exploredGridPos.X]; Tile.TileType exploredTerrain = map.getTileByPos(exploredGridPos.X, exploredGridPos.Y).TerrainType; if(openedNodes.Contains(exploredNode)) { int newCost = currentNode.MoveCost + GetMoveCost(previousMouvement, movement, exploredTerrain); if (newCost < exploredNode.MoveCost) { exploredNode.Parent = currentNode; exploredNode.MoveCost = newCost; //Find nearest tile to the target (in case doesn't find path to target) //Only compares the node to the current nearest FindNearest(exploredNode); } } else { exploredNode.Parent = currentNode; exploredNode.MoveCost = currentNode.MoveCost + GetMoveCost(previousMouvement, movement, exploredTerrain); Vector2 exploredNodeWorldPos = map.getTileByPos(exploredGridPos.X, exploredGridPos.Y).Position; exploredNode.EstimatedRemainingCost = (int)(endPosition - exploredNodeWorldPos).Length(); //Find nearest tile to the target (in case doesn't find path to target) //Only compares the node to the current nearest FindNearest(exploredNode); openedNodes.Add(exploredNode); } } } } return closedNodes; } After that, I simply check if the end node is contained in the returned nodes. If so, I add the end node and each parent until I reach the start. If not, I add the nearestToTarget and each parent until I reach the start. I added a condition before calling FindPath so that only one unit can call a find path each frame (60 frame per second), but it makes no difference. I thought maybe I could solve this by allowing the find path to run in background while the game continues to run correctly, even if it takes a few frame (it is currently sequential sonce it is called in the update() of the unit if there's a target location but no path), but I don't really know how... I also though about sorting my opened nodes list by cost so I don't have to loop them, but I don't know if that would have an effect on the performance... Would there be other solutions? P.S. In the code, when I get the Move Cost, I check if the unit has to turn to perform the move, and the terrain type, nothing hard to do.

• Setting values and display Text in Android Spinner

  - by kaibuki

  Hi, I need help in setting up value and display text in spinner. as per now I am populating my spinner by array adapter e.g mySpinner.setAdapter(myAdapter); and as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. now in my case I want to make spinner like the drop down box, which we have in .NET. which holds a text and value. where as text is displayed and value is at back end. so if I change drop down box , I can either use its selected text or value. but its not happening in android spinner case. For Example: Text Value Cat 10 Mountain 5 Stone 9 Fish 14 River 13 Loin 17 so from above array I am only displaying non-living objects text, and what i want is that when user select them I get there value i.e. like when Mountain selected i get 5 I hope this example made my question a bit more clear... thankx

• jquery parseFloat assigning val to field

  - by user306472

  I have a select box that gives a description of a product along with a price. Depending on what the user selects, I'd like to automatically grab that dollar amount from the option selected and assign it to a price input field. My HTML: <tr> <td> <select class="selector"> <option value="Item One $500">Item One $500</option> <option value="Item Two $400">Item Two $400</option> </select> </td> <td> <input type="text" class="price"></input> </td> </tr> So based on what is selected, I want either 500 or 400 assigned to the .class input. I tried this but I'm not quite sure where I'm going wrong: $('.selector').blur(function(){ var selectVal = ('.selector > option.val()'); var parsedPrice = parseFloat(selectVal.val()); $('.price').val(parsedPrice); });

• Databinding a multiselect ListBox in a FormView control

  - by drs9222

  I have a multiselect ListBox within a FormView. I can't figure out how to setup the databinding for it. I can populate the listbox fine. If the listbox was a single select I could use say SelectValue='<%#Bind("col")%>' and that works fine. Is there something that I can bind to for a multiselect listbox? I've tried manually DataBinding by handling the DataBinding event of the listbox and setting the selected property on the appropriate items. Unfortunately, there are no items in the listbox during the DataBinding event. The closest thing I've found is to save the value that determines what items should be selecting during DataBinding and then use that value in the FormViews DataBinding event to select the right items which seems like a hack to me. Is there a better way? EDIT: To clarify what I am currently doing... I am using the FormViews's ItemCreated event to save the FormView's DataItem. Then in the FormView's DataBound event I find the listbox and manually set the selected items. It doesn't seem right that I have to save the value like this and I assume there is a more correct way to do this that I just can't see.

• [ckeditor] apply font size using execCommand

  - by Wiika

  Hi all, var wgetFrame = window.frames[0] wframeDoc = wgetFrame.document; editor.focus(); editor.execCommand('bold'); wframeDoc.execCommand('forecolor',false,'#00ff00'); wframeDoc.execCommand('JustifyCenter', false, null); wframeDoc.execCommand('fontsize', false, 15); (i use the code above as a plugin in CKEditor) bold, forecolor and JustifyCenter , they all rend corectly , the selected text is wrapped by a span element but when applying the fontsize command , the selected goes inside the font element, i know this is correct, but it need it to be inside a span element i need to know why bold, forecolor and JustifyCenter are wrapped by span and fontsize not !! and also if there another way to apply this styles ( ps : i run those commands when ckeditor is initialized, even if the editort doesn't contain any text, when u write the style definied is applied ) CKEDITOR.editorConfig = function(config) { CKEDITOR.addStylesSet('customStyles', [ { name: 'Header 1', element: 'h1' }, { name: 'Header 2', element: 'h2' }, { name: 'Header 3', element: 'h3' }, { name: 'Text', element: 'p' }, { name: 'Left Align', element: 'img', attributes: { 'class': 'ImageLeft'} }, { name: 'Right Align', element: 'img', attributes: { 'class': 'ImageRight'} } ]); }; can i apply editor.execCommand( "Header 1" ); ??

• <rich:datatable> and <rich:datascroller> problem

  - by Bariscan

  Hi all, I am developing a Seam-Jsfv1.2-EJB3 web app. I have a datatable and checkboxes in each row. Moreover, I have a datascroller at the bottom of my table as well. My problem is when I click the next page number from the scroller, the selected checkboxes at the first page of the datatable is gone. I mean, even if they were selected, clicking the next page make them deselected. I see it by going back to the first page again by clicking the scroller. Do you have any idea about that problem? In order to clearify my case, I attached my code below: <rich:dataTable id="apiV2ProductList" rows="10" var="_apiV2Product" value="#{apiV2ProductList.resultList}" rendered="#{not empty apiV2ProductList.resultList}" reRender="ds"> <rich:column> <f:facet name="header"> <h:selectBooleanCheckbox id="selectionCheckAll" onclick="selectAll()" /> </f:facet> <h:selectBooleanCheckbox id="selectionCheck" onclick="increase(this)" value="#{_apiV2Product.selectValue}" > </h:selectBooleanCheckbox> </rich:column> ... <f:facet name="footer"> <rich:datascroller id="ds" renderIfSinglePage="false"> </rich:datascroller> </f:facet> Many thanks in advance.

• InnerHTML IE 8 doesn't work properly? Resetting form.

  - by Craig Whitley

  Yeah this works in FF and Chrome, but for some reason wont work in IE 8. I'm using a radio button to clear a section of a form.. that section is a select box, but I don't want to leave the area empty - instead I want to reset it to what it was when the page loaded. At the moment IE8 is just leaving me with an empty small select box. Html: <select id="city_select" disabled="true" name="location_id" onchange="show_search_button();"><option selected>Select your city</option> </select> Javascript: document.getElementById('city_select').innerHTML = "<option selected>Select your city</option>"; I've also tried using location_id instead of city_select in the javascript but to no avail.. innerText and innerContent dont work either.. though the inner.HTML works in IE8 for an earlier function, but that isnt trying to innerHTML into a form. Does anybody know why this works in Chrome and FF but not IE8? and is there a solution to this? Any help appreciated thanks!

• ASP.NET AJAX Toolkit - CalendarExtender is reset on Postback

  - by user70192

  Hello, I have an ASP.NET page that has two input elements: A TextBox that is ReadOnly. This TextBox is the TargetControl of a CalendarExtender A DropDownList with AutoPostBack=true Here is the code: <table border="0" cellpadding="0" cellspacing="0"> <tr><td colspan="2">Date:</td></tr> <tr><td colspan="2"> <asp:TextBox ID="dateTextBox" runat="server" ReadOnly="true" /> <ajax:CalendarExtender ID="datePicker" runat="server" Format="MM/dd/yyyy" OnLoad="datePicker_Load" TargetControlID="dateTextBox" /> </td></tr> <tr><td colspan="2">Select an Option:</td></tr> <tr> <td>Name:&nbsp;</td> <td><asp:DropDownList ID="optionsDropDownList" runat="server" AutoPostBack="true" OnLoad="optionsDropDownList_Load" OnSelectedIndexChanged="optionsDropDownList_SelectedIndexChanged" DataTextField="Name" DataValueField="ID" /> </td></tr> <tr><td><asp:Button ID="saveButton" runat="server" Text="Save" OnClick="saveButton_Click" /></td></tr> </table> When the DropDownList posts back, the date selected by the user with the datePicker is reset to the current date. In addition, if I look at the Text property of dateTextBox, it is equal to string.Empty. How do I preserve the date that the user selected on a PostBack?
