  • Is there a SQL Server error numbers C# wrapper anyone knows of?

    - by Mr Grok
    I really want to do something useful when a PK violation occurs but I hate trapping error numbers... they just don't read right without comments (they're certainly not self documenting). I know I can find all the potential error numbers at SQL Server books online but I really want to be able to pass the error number to some helper class or look it up against a Dictionary of some sort rather than have non-descript err numbers everywhere. Has anyone got / seen any code anywhere that encapsulates the SQL Server Error numbers in this way as I don't want to re-invent the wheel (or I'm lazy maybe).

  • Flash Buttons Don't Work: TypeError: Error #1009: Cannot access a property or method of a null objec

    - by goldenfeelings
    I've read through several threads about this error, but haven't been able to apply it to figure out my situation... My flash file is an approx 5 second animation. Then, the last keyframe of each layer (frame #133) has a button in it. My flash file should stop on this last key frame, and you should be able to click on any of the 6 buttons to navigate to another html page in my website. Here is the Action Script that I have applied to the frame in which the buttons exist (on a separate layer, see screenshot at: http://www.footprintsfamilyphoto.com/wp-content/themes/Footprints/images/flash_buttonissue.jpg stop (); function babieschildren(event:MouseEvent):void { trace("babies children method was called!!!"); var targetURL:URLRequest = new URLRequest("http://www.footprintsfamilyphoto.com/portfolio/babies-children"); navigateToURL(targetURL, "_self"); } bc_btn1.addEventListener(MouseEvent.CLICK, babieschildren); bc_btn2.addEventListener(MouseEvent.CLICK, babieschildren); function fams(event:MouseEvent):void { trace("families method was called!!!"); var targetURL:URLRequest = new URLRequest("http://www.footprintsfamilyphoto.com/portfolio/families"); navigateToURL(targetURL, "_self"); } f_btn1.addEventListener(MouseEvent.CLICK, fams); f_btn2.addEventListener(MouseEvent.CLICK, fams); function couplesweddings(event:MouseEvent):void { trace("couples weddings method was called!!!"); var targetURL:URLRequest = new URLRequest("http://www.footprintsfamilyphoto.com/portfolio/couples-weddings"); navigateToURL(targetURL, "_self"); } cw_btn1.addEventListener(MouseEvent.CLICK, couplesweddings); cw_btn2.addEventListener(MouseEvent.CLICK, couplesweddings); When I test the movie, I get this error in the output box: "TypeError: Error #1009: Cannot access a property or method of a null object reference." The test movie does stop on the appropriate frame, but the buttons don't do anything (no URL is opened, and the trace statements don't show up in the output box when the buttons are clicked on the test movie). You can view the .swf file here: www.footprintsfamilyphoto.com/portfolio I'm confident that all 6 buttons do exist in the appropriate frame (frame 133), so I don't think that's what's causing the 1009 error. I also tried deleting each of the three function/addEventListener sections one at a time and testing, and I still got the 1009 error every time. If I delete ALL of the action script except for the "stop ()" line, then I do NOT get the 1009 error. Any ideas?? I'm very new to Flash, so if I haven't clarified something that I need to, let me know!

  • Java Runtime.freeMemory() returning bizarre results when adding more objects

    - by Sotirios Delimanolis
    For whatever reason, I wanted to see how many objects I could create and populate a LinkedList with. I used Runtime.getRuntime().freeMemory() to get the approximation of free memory in my JVM. I wrote this: public static void main(String[] arg) { Scanner kb = new Scanner(System.in); List<Long> mem = new LinkedList<Long>(); while (true) { System.out.println("Max memory: " + Runtime.getRuntime().maxMemory() + ". Available memory: " + Runtime.getRuntime().freeMemory() + " bytes. Press enter to use more."); String s = kb.nextLine(); if (s.equals("m")) for (int i = 0; i < 1000000; i++) { mem.add(new Long((new Random()).nextLong())); } } } If I write in m, the app adds a million Long objects to the list. You would think the more objects (to which we have references, so can't be gc'ed), the less free memory. Running the code: Max memory: 1897725952. Available memory: 127257696 bytes. m Max memory: 1897725952. Available memory: 108426520 bytes. m Max memory: 1897725952. Available memory: 139873296 bytes. m Max memory: 1897725952. Available memory: 210632232 bytes. m Max memory: 1897725952. Available memory: 137268792 bytes. m Max memory: 1897725952. Available memory: 239504784 bytes. m Max memory: 1897725952. Available memory: 169507792 bytes. m Max memory: 1897725952. Available memory: 259686128 bytes. m Max memory: 1897725952. Available memory: 189293488 bytes. m Max memory: 1897725952. Available memory: 387686544 bytes. The available memory fluctuates. How does this happen? Is the GC cleaning up other things (what other things are there on the heap to really clean up?), is the freeMemory() method returning an approximation that's way off? Am I missing something or am I crazy?

  • How to get rid of this w3 validation error?

    - by Pandiya Chendur
    I developed a web page and now i am validating it with w3c HTML4.0... I got one error it says Error Line 30, Column 57: there is no attribute "DATA-FLEXMENU" href="about.php" class="mainlink" data-flexmenu="flexmenu1">About Us</a></div> You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead). Any ways of getting rid of this error .... Any suggestion...

  • How to set which version of the VC++ runtime Visual Studio 2005 targets

    - by TallGuy
    I have an application that contains a VC++ project (along with C# projects). Previously, (i.e. during the last year or so) when a build has been done, Visual Studio 2005 appears to be targeting the VC++ runtime version 8.0.50727.762. At least, that is what the Assembly.dll.intermediate.manifest file is telling me: <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.VC80.CRT' version='8.0.50727.762' processorArchitecture='x86' publicKeyToken='1fc8b3b9a1e18e3b' /> </dependentAssembly> </dependency> </assembly> This version number matches the Visual Studio 2005 version number. The application worked fine when deployed to the webserver. The sun was shining, the birds were singing and all was right with the world. Now something has changed. I don't know what - a security patch, an obscure Visual Studio setting or something. Now Visual Studio 2005 seems to be targeting the wrong version of the VC++ runtime: <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.VC80.CRT' version='8.0.50727.4053' processorArchitecture='x86' publicKeyToken='1fc8b3b9a1e18e3b' /> </dependentAssembly> </dependency> </assembly> When I deploy the application to the webserver, I get the dreaded This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1) error. This problem occurs even when I recompile previous versions of the application. I can absolutely guarantee that nothing at all has changed in the solution - we zip up the entire contents of the solution as part of the build process and archive it. I have unzipped a number of these to a temp directory, verified that the previous manifest file refers to 8.0.50727.762, recompiled using exactly the same command at the command line and then verified that the new manifest file now refers to 8.0.50727.4053. I am using Microsoft Visual Studio 2005 Version 8.0.50727.762 (SP.050727-7600) and Microsoft Visual C++ 2005 77646-008-0000007-41610. Why would Visual Studio revert to a previous version of the VC++ runtime? How do I specify which version it should use? What is going wrong here?

  • What is the safest way to subtract two System.Runtime.InteropServices.ComTypes.FILETIME objects

    - by Anindya Chatterjee
    I wonder what is the safest way to subtract two System.Runtime.InteropServices.ComTypes.FILETIME objects? I used the following code but sometimes it gives me ArithmaticOverflow exception due to the negative number in Low 32-bit values. I am not sure enclosing the body with unchecked will serve the purpose or not. Please give me some suggestion on how to do it safely without getting any runtime exception or CS0675 warning message. private static UInt64 SubtractTimes(FILETIME a, FILETIME b) { UInt64 aInt = ((UInt64)(a.dwHighDateTime << 32)) | (UInt32)a.dwLowDateTime; UInt64 bInt = ((UInt64)(b.dwHighDateTime << 32)) | (UInt32)b.dwLowDateTime; return aInt - bInt; }

  • Php code not executing - dies out when trying to refer to member of static class - no error displaye

    - by Ali
    I'm having some problems with this piece of code. I've included a class declaration and trying to create an object of that class but my code dies out. It doesn't seem to be an include issue as all the files are being included even the files called for inclusion within the class file itself. However the object is not created - I tried to put an echo statement in the __construct function but nothing it just doesn't run infact doesn't create the object and the code won't continue from there - plus no error is reported or displayed and I have error reporting set to E_ALL and display errors set to true WHats happening here :( =============EDIT SOrry I checked again the error is prior to teh object creation thing - it dies out when it tries to refer to a constant in a static class like so: $v = Zend_Oauth::REQUEST_SCHEME_HEADER; THis is the class or part of it - it has largely static functions its the Zend Oauth class: class Zend_Oauth { const REQUEST_SCHEME_HEADER = 'header'; const REQUEST_SCHEME_POSTBODY = 'postbody'; const REQUEST_SCHEME_QUERYSTRING = 'querystring'; // continued LIke I said no error is being reported at all :(

  • Implementing a runtime Look Up Table in C#

    - by Yarok
    Hey all, I'm currently working on a robot interface GUI, using C#. The robot has two sensors, and two powered wheels. I need to let the user the option to load a Look Up Table (LUT) during runtime, one for each sensor, that will tell the robot what to do according to the sensor's reading. I think the best way to do it is using a .csv file, formatted like so: index , right wheel order, left wheel order the index is an int between 0-1023 and is actually the sensor's reading. the orders for the right and left wheel are integers, between -500 - 500. Example - left sensor's readings: 1,10,20 meaning: sensor reads 1 -- left wheel 10 rpm right wheel 20 rpm So my question is this: what is the best way to implement it? using a dataset?(if so, how?) using an array? (if so, how do I load it during runtime?) Any help would be much appreciated, Yarok

  • Can I add and remove elements of enumeration at runtime in Java

    - by Brabster
    It is possible to add and remove elements from an enum in Java at runtime? For example, could I read in the labels and constructor arguments of an enum from a file? @saua, it's just a question of whether it can be done out of interest really. I was hoping there'd be some neat way of altering the running bytecode, maybe using BCEL or something. I've also followed up with this question because I realised I wasn't totally sure when an enum should be used. I'm pretty convinced that the right answer would be to use a collection that ensured uniqueness instead of an enum if I want to be able to alter the contents safely at runtime.

  • How to further improve error messages in Scala parser-combinator based parsers?

    - by rse
    I've coded a parser based on Scala parser combinators: class SxmlParser extends RegexParsers with ImplicitConversions with PackratParsers { [...] lazy val document: PackratParser[AstNodeDocument] = ((procinst | element | comment | cdata | whitespace | text)*) ^^ { AstNodeDocument(_) } [...] } object SxmlParser { def parse(text: String): AstNodeDocument = { var ast = AstNodeDocument() val parser = new SxmlParser() val result = parser.parseAll(parser.document, new CharArrayReader(text.toArray)) result match { case parser.Success(x, _) => ast = x case parser.NoSuccess(err, next) => { tool.die("failed to parse SXML input " + "(line " + next.pos.line + ", column " + next.pos.column + "):\n" + err + "\n" + next.pos.longString) } } ast } } Usually the resulting parsing error messages are rather nice. But sometimes it becomes just sxml: ERROR: failed to parse SXML input (line 32, column 1): `"' expected but `' found ^ This happens if a quote characters is not closed and the parser reaches the EOT. What I would like to see here is (1) what production the parser was in when it expected the '"' (I've multiple ones) and (2) where in the input this production started parsing (which is an indicator where the opening quote is in the input). Does anybody know how I can improve the error messages and include more information about the actual internal parsing state when the error happens (perhaps something like a production rule stacktrace or whatever can be given reasonably here to better identify the error location). BTW, the above "line 32, column 1" is actually the EOT position and hence of no use here, of course.

  • sort a list of objects based on runtime property

    - by jijo
    I have an arraylist of VOs. These objects have many properties and corresponding get/set methods. I want to sort this array list based on a property which I'll be getting in runtime. Let me explain in detail. My VO is like this public class Employee { String name; String id; private String getName() { return name; } private String getId() { return id; } } I will be getting a string ‘sort’ in runtime, which can be either ‘id’ of ‘name’. I want to sort the list based on the value of the string. I have tried to use comparator and reflection together, but no luck. I don’t want to use an if loop and create new comparator classes. Any other thoughts?

  • Change Image in Resources at Runtime

    - by zaidwaqi
    Hi, My understanding of Resources is that I can combine resources i.e. images and my program into single executable. Let's say I have image pic1.png and I put it into Resource of my project, and is accessible with Properties.Resource.pic1. For example, PictureBox pb = new PictureBox(); pb.Image = Properties.Resource.pic1; What I want to do is for that my program will be able to replace this image at runtime. For example, my program runs, and locate newPicture.png, and use this new image to replace pic1.png that was originally used. Maybe my question is better reworded as "Can I include new image into Resources at runtime?" Please help. Thanks.

  • Call Generic method using runtime type and cast return object

    - by markpirvine
    I'm using reflection to call a generic method with a type determined at runtime. My code is as follows: Type tType = Type.GetType(pLoadOut.Type); MethodInfo method = typeof(ApiSerialiseHelper).GetMethod("Deserialise", new Type[] { typeof(string) }); MethodInfo generic = method.MakeGenericMethod(tType); generic.Invoke(obj, new object[] { pLoadOut.Data }); This works ok. However the generic.Invoke method returns an object, but what I would like is the type determined at runtime. Is this possible with this approach, or is there a better option? Mark

  • Word 2007 "Out of Memory or Disk Space" Error on launch.

    - by Adam
    Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

  • Empty Recycle Bin error "Cannot Delete Dc12: Access denied."

    - by Chris Noe
    The Dc number can vary. The error is a sporadic, but when it happens it prevents the contents of the recycle bin from being deleted. It can also occur when the recycle bin appears to be empty, yet it has the crumpled paper indicator. Rebooting makes the problem go away, but it can also magically go away by just waiting a long time, like over night. But the problem keeps recurring with no rhyme or reason. What is causing this? I really don't want to reinstall Windows.
