  • BI Publisher : Formatting Issues

    - by Manoj Madhusoodanan
    While creating BI Publisher reports the formatting issues are quite common.Here I am discussing some common issues related to BIP report development. 1) First issue is related to column formatting.When you want to display some data which has leading zeros or trailing zeros after '.' in EXCEL output you will not get the desired output.But in PDF it will come as what you are expecting.This is not with the issue of your data. This is due to the unique nature of EXCEL cell format.When you are trying to put a text data in a cell with out making any change to cell format it will treat as number and it will truncate all leading zeros and all trailing zeros after '.' . So what you have to do is to convert that data into a format which EXCEL can treat as text. Eg: If you want to display 0020100 convert this data into ="0020100". Same way for 23789.02300 to ="23789.02300".   Note: This is applicable to EXCEL output only.If you have multiple output type apply it only for EXCEL. 2) Second is related to report size issue in PDF output type.If the number of columns are more and if you want to show most of the columns in one row andif it is a PDF output you can choose the paper size as Legal (8.5 x 14''). You will get more spaces in the template to accommodate more columns. 3) If your XML data contains special characters like &,<,> etc ..  pass the data to DBMS_XMLGEN.CONVERT function.It will replace special characters with corresponding XML notations. Eg: (a>b) & (c!=d) to  (a&gt;b) &amp; (c!=d)

  • How can I pass an external instance to the constructor of an object that's being created using the default XNA XML content loader?

    - by Michael
    I'm trying to understand how to use the XNA XML content importer to instantiate non-trivial objects that are more than a collection of basic properties (e.g., a class that inherits from DrawableGameObject or GameObject and requires other things to be passed into its constructor). Is it possible to pass existing external instances (e.g., an instance of the current Game) to the constructor of an object that's being created using the default XNA XML content loader? For example, imagine that I have the following class, inheriting from DrawableGameComponent: public class Character : DrawableGameComponent { public string Name { get; set; } public Character(Game game) : base(game) { } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { } } If I had a simple class that did not need other parameters in its constructor (i.e., the Game instance), then I could simply use this XML: <XnaContent> <Asset Type="MyNamespace.Character"> <Name>John Doe</Name> </Asset> </XnaContent> ...and then create an instance of Character using this code: var character = Content.Load<Character>("MyXmlAssetName"); But that won't work because I need to pass the need to pass the Game into the constructor. What's the best way to handle this situation? Is there a way to pass in things like the current Game using the default XNA XML content loader? Do I need to write my own XML loader? (If so, how?) Is there a better object-oriented design that I should be using for my classes? Note: Although I used Game in this example, I'm really just asking how to pass any type of existing instance to my constructors. (For example, I'm using the Farseer Physics Engine, and some of my classes also need a reference to the Farseer World object too.) Thanks in advance.

  • Any advantage to the script version of Google Adwords' conversion tracking code?

    - by ripper234
    Google Adword has an HTML snippet to track conversions: <script type="text/javascript"> /* <![CDATA[ */ var google_conversion_id = 12345; var google_conversion_language = "en"; var google_conversion_format = "3"; var google_conversion_color = "ffffff"; var google_conversion_label = "someopaqueid"; var google_conversion_value = 0; /* ]]> */ </script> <script type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js"> </script> <noscript> <div style="display:inline;"> <img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/12345/?label=opaque&amp;guid=ON&amp;script=0"/> </div> </noscript> It is composed of two parts: For clients supporting javascript, an inline script that sets variables, plus loading a reporting script. For other clients, an image tag. As far as I can see, the image tag has some advantages: It works on all browsers. It is asynchronous. It's shorter to have only this version, compared to both this and the js version. Any reason not to drop the <noscript> tag and just use the image conversion snippet directly?

  • Capturing BizTalk 2004 SQLAdapter failures

    - by DanBedassa
    I was recently working on a BizTalk 2004 project where I encountered an issue with capturing exceptions (inside my orchestration) occurring from an external source. Like database server down, non-existing stored procedure, …   I thought I might write-up this in case it might help someone …   To reproduce an issue, I just rename the database to something different.   The orchestration was failing at the point where I make a SQL request via a Response-Request Port. The exception handlers were bypassed but I can see a warning in the event log saying: "The adapter failed to transmit message going to send port "   After scratching my head for a while (as a newbie to BTS 2004) to find a way to catch the exceptions from the SQLAdapter in an orchestration, here is the solution I had.   ·         Put the Send and Receive shapes inside a Scope shape ·         Set the Scope’s transaction type to “Long Running” ·         Add a Catch block expecting type “System.Exception” ·         Set the “Delivery Notification” of the associated Port to “Transmitted” ·         Change the “Retry Count” of the associated port to 0 (This will make sure BizTalk will raise the exception, instead of a warning, and you can capture that) ·         Now capture and do whatever with the exception inside the Catch block

  • Using the Java SE 8 Date Time API with JPA 2.1

    - by reza_rahman
    Most of you are hopefully aware of the new Date Time API included in Java SE 8. If you are not, you should check them out right now using the Java Tutorial Trail dedicated to the topic. It is a significantly leap forward in processing temporal data in Java. For those who already use Joda-Time the changes will look very familiar - very simplistically speaking the Java SE 8 feature is basically Joda-Time standardized. Quite naturally you will likely want to use the new Date Time APIs in your JPA domain model to better represent temporal data. The problem is that JPA 2.1 will not support the new API out of the box. So what are you to do? Fortunately you can make use of fairly simple JPA 2.1 Type Converters to use the Date Time API in your JPA domain classes. Steven Gertiser shows you how to do it in an extremely well written blog entry. Besides explaining the problem and the solution the entry is actually very good for getting a better understanding of JPA 2.1 Type Converters as well. I think such a set of converters may be a good fit for Apache DeltaSpike as a Java EE 7 extension? In case you are wondering about Java SE 8 support in the JPA specification itself, Nick Williams has already entered an excellent, well researched JIRA entry asking for such support in a future version of the JPA specification that's well worth looking at. Another possibility of course is for JPA providers to start supporting the Date Time API natively before anything is formalized in the specification. What do you think?

  • Ubuntu 12.04 slow boot on ASUS, attached with dmesg and bootchart

  • Provide an OnChange event for an internal property which is controlled externally?

    - by NGLN
    For fun and by request I am updating this ImageGrid component, a kind of listbox for images that has a FileNames property of type TStrings. For ease of writing, I have been misusing its FileNames.Objects property for bitmap storage. But since the TStrings type suggests that users of the component could or would want to use the Objects property for custom data, e.g. like TListBox.Items, I am rewriting the component to store the bitmaps elsewhere and leave FileNames.Objects untouched for unknown future usage. Now I am wondering whether to provide an OnChange event. And if so, whether to fire it when one or more FileNames.Objects changes. Trying to answer it myself, I dove in Delphi's own VCL and stumbled on: TMemo: has an OnChange event, but ignores Lines.Objects TListBox: has no OnChange event, but is capable of storing Items.Objects TStringGrid: has no OnChange event, but is capable of storing Objects, Rows.Objects, Cols.Objects So now I am somewhat puzzeled, because I cannot imagine Borland's developers didn't add events for several Objects properties out of ease. Sure, when a user changes a FileNames.Object in my component, he knows he does and could implement appropriate interaction himself. But wouldn't it be convenient when the component does automatically? What would you expect from this component in this regard?

  • Understanding Application binary interface (ABI)

    - by Tim
    I am trying to understand the concept of Application binary interface (ABI). From The Linux Kernel Primer: An ABI is a set of conventions that allows a linker to combine separately compiled modules into one unit without recompilation, such as calling conventions, machine interface, and operating-system interface. Among other things, an ABI defines the binary interface between these units. ... The benefits of conforming to an ABI are that it allows linking object files compiled by different compilers. From Wikipedia: an application binary interface (ABI) describes the low-level interface between an application (or any type of) program and the operating system or another application. ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; and in the case of a complete operating system ABI, the binary format of object files, program libraries and so on. I was wondering whether ABI depends on both the instruction set and the OS. Are the two all that ABI depends on? What kinds of role does ABI play in different stages of compilation: preprocessing, conversion of code from C to Assembly, conversion of code from Assembly to Machine code, and linking? From the first quote above, it seems to me that ABI is needed for only linking stage, not the other stages. Is it correct? When is ABI needed to be considered? Is ABI needed to be considered during programming in C, Assembly or other languages? If yes, how are ABI and API different? Or is it only for linker or compiler? Is ABI specified for/in machine code, Assembly language, and/or of C?

  • How to right align the search box [closed]

    - by Hai Vu
    I am a newbie in HTML, CSS. I am working on a simple web app using CherryPy and ran into the following problem. The page I serve has a h1 title and a form for search box. I would like to lay them out on the same line with the h1 left aligned and the form right align, like this: My H1 Title here [ ] Search But instead, I got them in two separate lines: My H1 Title here [ ] Search My HTML code: <span class="header"> <h1>${pagetitle}</h1> </span> <span class="searchbox"> <form> <input type="text" name="searchterm"> <input type="submit" value="Search"> </form> </span> My CSS: span.header { text-align: left; } span.searchbox { text-align: right; } I have tried to work around using table, but was told to use span to do the right thing. I appreciate your help to set it right.

  • Scrolling though objects then creating a new instace of this object

    - by gopgop
    In my game when pressing the right mouse button you will place an object on the ground. all objects have the same super class (GameObject). I have a field called selected and will be equal to one certain gameobject at a time. when clicking the right mouse button it checks whats the instance of selected and that how it determines which object to place on the ground. code exapmle: t is the "slot" for which the object will go to. if (selected instanceof MapleTree) { t = new MapleTree(game,highLight); } else if (selected instanceof OakTree) { t = new OakTree(game,highLight); } Now it has to be a "new" instance of the object. Eventually my game will have hundreds of GameObjects and I don't want to have a huge if else statement. How would I make it so it scrolls though the possible kinds of objects and if its the correct type then create a new instance of it...? When pressing E it will switch the type of selected and is an if else statement as well. How would I do it for this too? here is a code example: if (selected instanceof MapleTree) { selected = new OakTree(game); } else if (selected instanceof OakTree) { selected = new MapleTree(game); }

  • Why will Screenshot not show up in Dash?

    - by Bruce
    I'm relatively new to Ubuntu, and am running into a problem I've not seen before. This is on an Ubuntu 12.04 system. I can't find Screenshot. I'm trying to take a shot of a screen from a web page, go to Dash, type in Screenshot, and nothing shows up. I've done this many times before, but suddenly Screenshot is not found. I downloaded an app called Shutter, it seems to have installed just fine, but like Screenshot, I don't know how to find it. Dash reveals nothing. In Dash, I've noticed that I have no applications showing up in response to a search. For instance, I can type Firefox, and get no results either, even though I'm using Firefox to submit this question. Is there something I can do to get Dash to show applications? Search results show only files and folders, and downloads. I did find one answer on Ask Ubuntu, which gave the following instructions: None of these fixes worked for me. But after more searching: rm ~/.cache/software-center -R worked like a charm. I did need to run: unity --reset & afterwards though, for the changes to take effect within dash, but the software center just started working straightaway. However, when I issued the unity --reset & command, it resulted in an internal error, and I'll have to reboot in order to reset my computer (which fortunately is allowing me to complete this question). So I'm still wondering why applications won't show in Dash, and will appreciate any help.

  • Flow Fields in Dynamics NAV

    - by T
    I don’t know the exact business reason but someone asked how to identify all sales shipping orders with any negative quantities on them.  They needed to print these separately from the shipments that only have all positive quantities. Here is one way to solve this problem In NAV, open Sales Shipment Header Add a field of type Boolean (The field type should match the value you expect to return from the flow field method.  In this case we will use an exist so we expect a bool but we could have used a Sum, Average, Min, Max, Count, or a Lookup to return a value). Define it as a flow field and click on the ellipse next to CalcFormula Now [Has Negative Qty] is false if no negatives exist And [Has Negative Qty] and true if a negative exist So it is ready to be used as a filter on the report. Don’t forget that if you are using it in code, you may need to CalcFields. Hope that helps.  If you really can’t afford the field in your header, you can use code to check the lines for a negative value each time and use a skip or break function to skip that header record but it seems expensive to check them all if you only want a few to print. Please let me know if you think of a better solution.

  • Adventures in Lab Management Configuration: CMMI Edition Part 1 of 3

    - by Enrique Lima
    I remember at one point someone telling me how close Migrate was to Migraine. This was a process that included an environment from TFS 2008 to TFS 2010, needed to be migrated too as far as the process template goes.  Here we are talking about CMMI v4.2 to CMMI v5.0.  Now, the process to migrate the TFS Infrastructure is one thing, migrating the Process Template is a different deal, not hard … just involved. Followed a combination of steps that came from a blog post as the main guidance and then MSDN (as suggested on the guidance post) to complement some tasks and steps. Again, the focus I have here is CMMI. The high level steps taken to enable the TFS 2008 CMMI v4.2 migrated to TFS 2010 Process Template are: 1)  Backup the Collection, Configuration and Warehouse Databases. 2)  Downloaded the Process Template using Visual Studio 2010. 3) Exported, modified and imported Bug Type Definition 4) Exported, modified and imported Scenario or Requirement Type Definition. 5) Created and imported bug field mappings. Now, we can attempt to connect using Test Manager, and you should be able to get this going. After that was done, it was time to enroll VMs that already existed in the environment.  This was a bit more challenging, but in the end it was a matter of just analyzing the changes that had been made to had a temporary work around from the time we migrated to the time we converted the Work Items and such and added fields to enable communication between the project and the Test and Lab Manager component. There are 2 more parts to this post, the second will describe the detailed steps taken to complete the Process Template update and the third will talk about the gotchas and fixes for the Lab Management portion.

  • What's hot in Oracle Premier Support News for Solaris, Storage and Systems - How to Patch!

    - by user12244613
    Struggling with locating patches for Sun products? Can't find your Oracle System Drivers? This question has been raised many times by customers and was the source of a short video in the Oracle System Support Newsletter in February 2012. The transition between SunSolve and My Oracle Support is to change how you think about the type of patch your looking for. For example, in SunSolve you might have typed e1000g if looking for an Enternet Driver.. but entering e1000g will not find anything in My Oracle Support - Patches and Update Menu. As you need to use the Product (Advanced) search which is driven of the Product Name, therefore you need to type "Ethernet" and select the ethernet product you are looking for to locate the patches for this product. Just to recap that video: If you are looking for the e1000g Ethernet Driver - You need to use Advance Search and search for Enternet 1. Log into My Oracle Support - Select Patches and Updates - Select Product or Family (Advanced Search). 2. In the product line enter: Ethernet and select the product name from the menu. 3. Check remove supersede patches - that ensure you only get relevant current patches in the results. 4. Select Search and the results are displayed. Now you have more options to include the platform (Solaris,Linux etc.) if want to further narrow the search. Need more information? Log into My Oracle Support and what a short 90sec video I put together. View the 7 minute Video using Firefox/chrome – It shows searching for individual patches, Solaris, Firmware etc. If you are not receiving the Oracle System Support Newsletter: Option (a) Within My Oracle Support, make document id: 1363390.1 a favourite and revisit it on the 2nd of each month for the latest content. Option (b) By default the Newsletter  is sent to all customers who have logged a Service Request on an Oracle Systems Hardware Product during the last 12months, unless you have opted out to receiving Oracle Communications on your profile on http://oracle.com

  • Inexplicable low ranking [closed]

    - by Mick
    I have created two similar websites relating to monetary systems. So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. The successful one is fullreservebanking.com. If you type in "full reserve banking" into Google, my site appears 2nd in the list behind Wikipedia. The unsuccessful one is fractionalreserves.com. If you type in "fractional reserve banking" into Google, it's nowhere to be seen. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for fullreservebanking, but fractionalreserves is just an "add-on" which sits on a subdirectory of fullreservebanking. I wonder if Google somehow detects this and treats it as a less significant website?

  • The idea of functionN in Scala / Functionaljava

    - by Luke Murphy
    From brain driven development It turns out, that every Function you’ll ever define in Scala, will become an instance of an Implementation which will feature a certain Function Trait. There is a whole bunch of that Function Traits, ranging from Function1 up to Function22. Since Functions are Objects in Scala and Scala is a statically typed language, it has to provide an appropriate type for every Function which comes with a different number of arguments. If you define a Function with two arguments, the compiler picks Function2 as the underlying type. Also, from Michael Froh's blog You need to make FunctionN classes for each number of parameters that you want? Yes, but you define the classes once and then you use them forever, or ideally they're already defined in a library (e.g. Functional Java defines classes F, F2, ..., F8, and the Scala standard library defines classes Function1, ..., Function22) So we have a list of function traits (Scala), and a list of interfaces (Functional-java) to enable us to have first class funtions. I am trying to understand exactly why this is the case. I know, in Java for example, when I write a method say, public int add(int a, int b){ return a + b; } That I cannot go ahead and write add(3,4,5); ( error would be something like : method add cannot be applied to give types ) We simply have to define an interface/trait for functions with different parameters, because of static typing?

  • Installing 13.04 on an EFI partition - Share with Windows 8?

    - by mengelkoch
    Information I've found here suggests that for my system, I need to install 13.04 into an EFI-type partition, since it needs to boot as UEFI. I also understand it is advisable to have only ONE EFI partition on the disk; I've read here that it is OK for Ubuntu and Windows to share the same partition (please confirm). When I try to install into the existing EFI drive, I get the message "No root file system is defined. Please correct from partitioning menu." Do I change the EFI boot partition to another type? Doesn't that defeat the purpose? If I change it to Ext4 Journaling File System, I am given the opportunity to define the '/' Mount point. I haven't proceeded beyond this point for fear I am going to destroy Windows 8 by altering this partition. BTW, I created three partitions in Windows before installing, per the helpful response to my previous question. But if I try to install into the partition I created for Ubuntu, I get the "No root file system..." error again.

    I have an X-series Asus laptop which I just bough about a month ago. I want to dualboot Ubuntu - Windows. I can easily access LiveUSB with both UEFI enabled and disabled. I heard that there were problems with UEFI, so I disabled it. After I've installed the system I couldn't access it. It just boots to Windows straight. Another unusual thing, that never happened to me before was that the partition editor wanted me to create a BIOS reserved area, which I did, but not at the beginning of the table. Any ideas how to access the Ubuntu partition? As far as I can guess both Windows and Ubuntu have to be both of the same type of boot, either Legacy or EFI. This is not the case of what I have now. So, if I reinstall Ubuntu in UEFI mode that correlates with my Windows type, will I then be able to boot into it? I have a constraint, my laptop doesn't have a CD ROM, so I cannot reinstall WIndows, nor can I move around the Windows recovery partition. This is the boot-repair report : http://paste.ubuntu.com/1354254/

  • I need a form to tie MySQL Records together.

    - by John R
    I need a HTML-based form to tie database records together. The user scenario that I envision is somthing like this: A super-user does a search of the database and is delivered a table of records based on that search; each record is numbered with the database-record id. There would also be two text fields next to each record. These text fields would allow: the user to make a reference from one record to another. For example, a user could enter into record id #457 the integer 242 to indicate that there is a correlation with record ID #242. The user would also describe the type of relationship it is. This could be accomplished with a simple integer in the second field that indicates the type of relationship between the two records. When the super-user hits the submit button, all of these relationships are saved in a mySqljoin table. One option is to give me advice on how to implement and code this myself in PHP. However, before I reinvent the wheel, another option is to lead me to a free script that does something similar.

  • receiving "command not found" error messages after fresh reinstall of Lubuntu 14.04

    - by user236378
    Lubuntu 14.04 was working really great. . .until I messed up and had to do a complete fresh reinstall. Now I receive error messages when I input commands into the Terminal, even after immediately completing the fresh install. For example I type: sudo leafpad ?/etc/default/ or sudo leafpad ?/etc/default/grub I get: sudo: leafpad: command not found I type: sudo update-initramfs ?-u or sudo update-grub I get: sudo: update-initramfs: command not found or sudo: update-grub: command not found If I use the command mkdir I get: mkdir: command not found I also get this same exact error message, command not found, with sudo apt-get and wget In other words I can't do anything that I was able to do when inputting commands into the terminal. So I cannot add any repositories or update anything at all. I am not really sure what is causing the problem(s). It appeared to me that Lubuntu installed and booted up OK. However just as soon as I enter anything into the Terminal I immediately get the above error messages. I have tried to do the reinstall three times, same error messages. If anyone can suggest any fixes I would really appreciate it very much. Thank you!

  • Using VirtualBox to test drive Windows Blue

    - by Fat Bloke
    Oracle VM VirtualBox is great for trying out the latest and greatest technologies and platforms. So when Microsoft recently announced the Developer Preview for Windows Server 2012 R2 and Windows 8.1,  it was with eager anticipation that FatBloke ran to the TechNet Evaluation Center to download the isos. Once downloaded,  a new VM in VirtualBox Manager was created that used Windows 2012 (64-bit) OS type and all the defaults were selected. And on starting the VM, and pointing to the iso file to install from, the excitement rose as we saw a cool new splashscreen image: But suddenly our hopes are dashed.... It would seem that this platform requires an instruction (CMPXCHG16B) that VirtualBox doesn't offer "out-of-the-box".  Fear not, for the VirtualBox team knew that this day would finally arrive and have prepared an "in case of emergency" switch as follows: Power off the vm; At the command line type:  VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1 Start the VM and install Windows Server 2012 R2 This will be enabled by default in a future release, but geeks can't wait, hence this blog. Enjoy! -FB

  • USB flash module giving errors

    - by vshenoy
    Hi, I have a SATA USB flash module which was earlier running a 2.4 linux kernel (2.4.36.6) and on which now I am trying to install ubuntu server 10.04.1 LTS. I have two such USB flash modules and on one of them the installation process itself giving these errors: sd 4:0:0:0 [sda] Device not ready sd 4:0:0:0 [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 4:0:0:0 [sda] Sense Key : Not Ready [current] sd 4:0:0:0 [sda] Add. Sense: Medium not present sd 4:0:0:0 [sda] CDB: Write(10): 2a 00 00 05 48 02 00 00 04 00 end_request: I/O error, dev sda, sector 46114 usb 1-1: reset high speed USB device using ehci_hcd and address 2 Buffer I/O error on device sda1, logical block 172033 lost page write due to I/O error on sda1 Buffer I/O error on device sda1, logical block 172034 lost page write due to I/O error on sda1 on the other the installation is successful, but after a day or two of running the machine hangs because of kernel spewing these messages: Remounting filesystem read-only EXT2-fs error (device sda1): read_block_bitmap: Cannot read block [bitmap - block_group = 105, block_bitmap = 860161] EXT2-fs error (device sda1): ext2_get_inode: unable to read inode block - inode=13083, block=24683 ext2_free_inode: bit already cleared for inode 83966 and the machine needs to be hard rebooted. On both the systems SCSI emulation with usb_storage driver is being used to detect the module. Here is the output of /proc/scsi/scsi on 2.4: # cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: TS Model: UFM Rev: 1100 Type: Direct-Access ANSI SCSI revision: 02 and on 2.6: # cat /proc/scsi/scsi Attached devices: Host: scsi6 Channel: 00 Id: 00 Lun: 00 Vendor: TS Model: UFM Rev: 1100 Type: Direct-Access ANSI SCSI revision: 00 i.e. only 'ANSI SCSI revision:' is shown as different, although I am not sure if this can cause any problem. Really appreciate if someone can point as to how to debug this issue or any mailing list where I can further ask questions about this.
