StackOverFlowError while creating Mac object on AS400/Java

- by Prasanna K Rao

Hello all, I am a newbie to AS400-Java programming. I am trying to create my first program to test the implementation of Message Authentication Code (MAC). I am trying to use the HMACSHA1 hash function. My (Java 1.4) program runs fine on a dev box (V5R4).But fails terribly on the QA box (V5R3). My program is as below: ===================================================== import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.security.Security; import java.security.Provider; import javax.crypto.Mac; import javax.crypto.spec.SecretKeySpec; import javax.crypto.SecretKey; public class Test01 { private static final String HMAC_SHA1_ALGORITHM = "HmacSHA1"; public static void main (String [] arguments) { byte[] key = { 1,2,3,4,5,6,7,8}; SecretKeySpec SHA1key = new SecretKeySpec(key, "HmacSHA1"); Mac hmac; String strFinalRslt = ""; try { hmac = Mac.getInstance("HmacSHA1"); hmac.init(SHA1key); byte[] result = hmac.doFinal(); strFinalRslt = toHexString(result); }catch (NoSuchAlgorithmException e) { // TODO Auto-generated catch block e.printStackTrace(); }catch (InvalidKeyException e) { // TODO Auto-generated catch block e.printStackTrace(); }catch(StackOverflowError e){ e.printStackTrace(); } System.out.println(strFinalRslt); System.out.println("All done!!!"); } public static byte[] fromHexString ( String s ) { int stringLength = s.length(); if ( (stringLength & 0x1) != 0 ) { throw new IllegalArgumentException ( "fromHexString requires an even number of hex characters" ); } byte[] b = new byte[stringLength / 2]; for ( int i=0,j=0; i 4] ); //look up low nibble char sb.append( hexChar [b[i] & 0x0f] ); } return sb.toString(); } static char[] hexChar = { '0' , '1' , '2' , '3' , '4' , '5' , '6' , '7' , '8' , '9' , 'a' , 'b' , 'c' , 'd' , 'e' , 'f'}; } This program compiles fine and gets the correct response on my win-xp client and also my dev box. But, fails with the following error on the QA box: java.lang.StackOverflowError at java.lang.Throwable.(Throwable.java:180) at java.lang.Error.(Error.java:37) at java.lang.StackOverflowError.(StackOverflowError.java:24) at java.io.Os400FileSystem.list(Native method) at java.io.File.list(File.java:922) at javax.crypto.b.e(Unknown source) at javax.crypto.b.a(Unknown source) at javax.crypto.b.c(Unknown source) at javax.crypto.b£0.run(Unknown source) at javax.crypto.b.(Unknown source) at javax.crypto.Mac.getInstance(Unknown source) I have verified the java.security file and entry corresponding to the jce files are all ok. The DMPJVM command gives me the following response: Thu Jun 03 12:25:34 E Java Virtual Machine Information 016822/QPGMR/11111 ........................................................................ .

Fitting an Image to Screen on Rotation iPhone / iPad ?

- by user356937

I have been playing around with one of the iPhone examples from Apple' web site (ScrollViewSuite) . I am trying to tweak it a bit so that when I rotate the the iPad the image will fit into the screen in landscape mode vertical. I have been successful in getting the image to rotate, but the image is larger than the height of the landscape screen, so the bottom is below the screen. I would like to image to scale to the height of the landscape screen. I have been playing around with various autoSizingMask attributes without success. The imageView is called "zoomView" this is the actual image which loads into a scrollView called imageScrollView. I am trying to achieve the screen to rotate and look like this.... olsonvox.com/photos/correct.png However, this is what My screen is looking like. olsonvox.com/photos/incorrect.png I would really appreciate some advice or guidance.

ruby regex, parsing html

- by danwoods

Hello all, I'm trying to parse some returned html to look for currently playing movies. The pattern I'm trying to match looks like: <span dir=ltr>Clash of the Titans</span> Of which there are several in the returned html. (the html is huge, I've posted a sample at the bottom) I'm trying get an array of the movie titles with the following command: titles = listings_html.split(/(<span dir=ltr>).*(<\/span>)/) But I'm not getting the results I'm expecting. Can anyone see a problem with my approach or regex? Returned html (I believe the 'markdown'formating will render the some of the html, but this is just an example): <script>window.gbar={};(function(){function h(a,b,d){var c="on"+b;if(a.addEventListener)a.addEventListener(b,d,false);else if(a.attachEvent)a.attachEvent(c,d);else{var f=a[c];a[c]=function(){var e=f.apply(this,arguments),g=d.apply(this,arguments);return e==undefined?g:g==undefined?e:g&&e}}};var i=window.gbar,k,l,m;function n(a){var

UIImagePickerController, UIImage, Memory and More!

- by Itay

I've noticed that there are many questions about how to handle UIImage objects, especially in conjunction with UIImagePickerController and then displaying it in a view (usually a UIImageView). Here is a collection of common questions and their answers. Feel free to edit and add your own. I obviously learnt all this information from somewhere too. Various forum posts, StackOverflow answers and my own experimenting brought me to all these solutions. Credit goes to those who posted some sample code that I've since used and modified. I don't remember who you all are - but hats off to you! How Do I Select An Image From the User's Images or From the Camera? You use UIImagePickerController. The documentation for the class gives a decent overview of how one would use it, and can be found here. Basically, you create an instance of the class, which is a modal view controller, display it, and set yourself (or some class) to be the delegate. Then you'll get notified when a user selects some form of media (movie or image in 3.0 on the 3GS), and you can do whatever you want. My Delegate Was Called - How Do I Get The Media? The delegate method signature is the following: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info; You should put a breakpoint in the debugger to see what's in the dictionary, but you use that to extract the media. For example: UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage]; There are other keys that work as well, all in the documentation. OK, I Got The Image, But It Doesn't Have Any Geolocation Data. What gives? Unfortunately, Apple decided that we're not worthy of this information. When they load the data into the UIImage, they strip it of all the EXIF/Geolocation data. Can I Get To The Original File Representing This Image on the Disk? Nope. For security purposes, you only get the UIImage. How Can I Look At The Underlying Pixels of the UIImage? Since the UIImage is immutable, you can't look at the direct pixels. However, you can make a copy. The code to this looks something like this: UIImage* image = ...; // An image NSData* pixelData = (NSData*) CGDataProviderCopyData(CGImageGetDataProvider(image.CGImage)); unsigned char* pixelBytes = (unsigned char *)[pixelData bytes]; // Take away the red pixel, assuming 32-bit RGBA for(int i = 0; i < [pixelData length]; i += 4) { pixelBytes[i] = 0; // red pixelBytes[i+1] = pixelBytes[i+1]; // green pixelBytes[i+2] = pixelBytes[i+2]; // blue pixelBytes[i+3] = pixelBytes[i+3]; // alpha } However, note that CGDataProviderCopyData provides you with an "immutable" reference to the data - meaning you can't change it (and you may get a BAD_ACCESS error if you do). Look at the next question if you want to see how you can modify the pixels. How Do I Modify The Pixels of the UIImage? The UIImage is immutable, meaning you can't change it. Apple posted a great article on how to get a copy of the pixels and modify them, and rather than copy and paste it here, you should just go read the article. Once you have the bitmap context as they mention in the article, you can do something similar to this to get a new UIImage with the modified pixels: CGImageRef ref = CGBitmapContextCreateImage(bitmap); UIImage* newImage = [UIImage imageWithCGImage:ref]; Do remember to release your references though, otherwise you're going to be leaking quite a bit of memory. After I Select 3 Images From The Camera, I Run Out Of Memory. Help! You have to remember that even though on disk these images take up only a few hundred kilobytes at most, that's because they're compressed as a PNG or JPG. When they are loaded into the UIImage, they become uncompressed. A quick over-the-envelope calculation would be: width x height x 4 = bytes in memory That's assuming 32-bit pixels. If you have 16-bit pixels (some JPGs are stored as RGBA-5551), then you'd replace the 4 with a 2. Now, images taken with the camera are 1600 x 1200 pixels, so let's do the math: 1600 x 1200 x 4 = 7,680,000 bytes = ~8 MB 8 MB is a lot, especially when you have a limit of around 24 MB for your application. That's why you run out of memory. OK, I Understand Why I Have No Memory. What Do I Do? There is never any reason to display images at their full resolution. The iPhone has a screen of 480 x 320 pixels, so you're just wasting space. If you find yourself in this situation, ask yourself the following question: Do I need the full resolution image? If the answer is yes, then you should save it to disk for later use. If the answer is no, then read the next part. Once you've decided what to do with the full-resolution image, then you need to create a smaller image to use for displaying. Many times you might even want several sizes for your image: a thumbnail, a full-size one for displaying, and the original full-resolution image. OK, I'm Hooked. How Do I Resize the Image? Unfortunately, there is no defined way how to resize an image. Also, it's important to note that when you resize it, you'll get a new image - you're not modifying the old one. There are a couple of methods to do the resizing. I'll present them both here, and explain the pros and cons of each. Method 1: Using UIKit + (UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize; { // Create a graphics image context UIGraphicsBeginImageContext(newSize); // Tell the old image to draw in this new context, with the desired // new size [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)]; // Get the new image from the context UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext(); // End the context UIGraphicsEndImageContext(); // Return the new image. return newImage; } This method is very simple, and works great. It will also deal with the UIImageOrientation for you, meaning that you don't have to care whether the camera was sideways when the picture was taken. However, this method is not thread safe, and since thumbnailing is a relatively expensive operation (approximately ~2.5s on a 3G for a 1600 x 1200 pixel image), this is very much an operation you may want to do in the background, on a separate thread. Method 2: Using CoreGraphics + (UIImage*)imageWithImage:(UIImage*)sourceImage scaledToSize:(CGSize)newSize; { CGFloat targetWidth = targetSize.width; CGFloat targetHeight = targetSize.height; CGImageRef imageRef = [sourceImage CGImage]; CGBitmapInfo bitmapInfo = CGImageGetBitmapInfo(imageRef); CGColorSpaceRef colorSpaceInfo = CGImageGetColorSpace(imageRef); if (bitmapInfo == kCGImageAlphaNone) { bitmapInfo = kCGImageAlphaNoneSkipLast; } CGContextRef bitmap; if (sourceImage.imageOrientation == UIImageOrientationUp || sourceImage.imageOrientation == UIImageOrientationDown) { bitmap = CGBitmapContextCreate(NULL, targetWidth, targetHeight, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo); } else { bitmap = CGBitmapContextCreate(NULL, targetHeight, targetWidth, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo); } if (sourceImage.imageOrientation == UIImageOrientationLeft) { CGContextRotateCTM (bitmap, radians(90)); CGContextTranslateCTM (bitmap, 0, -targetHeight); } else if (sourceImage.imageOrientation == UIImageOrientationRight) { CGContextRotateCTM (bitmap, radians(-90)); CGContextTranslateCTM (bitmap, -targetWidth, 0); } else if (sourceImage.imageOrientation == UIImageOrientationUp) { // NOTHING } else if (sourceImage.imageOrientation == UIImageOrientationDown) { CGContextTranslateCTM (bitmap, targetWidth, targetHeight); CGContextRotateCTM (bitmap, radians(-180.)); } CGContextDrawImage(bitmap, CGRectMake(0, 0, targetWidth, targetHeight), imageRef); CGImageRef ref = CGBitmapContextCreateImage(bitmap); UIImage* newImage = [UIImage imageWithCGImage:ref]; CGContextRelease(bitmap); CGImageRelease(ref); return newImage; } The benefit of this method is that it is thread-safe, plus it takes care of all the small things (using correct color space and bitmap info, dealing with image orientation) that the UIKit version does. How Do I Resize and Maintain Aspect Ratio (like the AspectFill option)? It is very similar to the method above, and it looks like this: + (UIImage*)imageWithImage:(UIImage*)sourceImage scaledToSizeWithSameAspectRatio:(CGSize)targetSize; { CGSize imageSize = sourceImage.size; CGFloat width = imageSize.width; CGFloat height = imageSize.height; CGFloat targetWidth = targetSize.width; CGFloat targetHeight = targetSize.height; CGFloat scaleFactor = 0.0; CGFloat scaledWidth = targetWidth; CGFloat scaledHeight = targetHeight; CGPoint thumbnailPoint = CGPointMake(0.0,0.0); if (CGSizeEqualToSize(imageSize, targetSize) == NO) { CGFloat widthFactor = targetWidth / width; CGFloat heightFactor = targetHeight / height; if (widthFactor > heightFactor) { scaleFactor = widthFactor; // scale to fit height } else { scaleFactor = heightFactor; // scale to fit width } scaledWidth = width * scaleFactor; scaledHeight = height * scaleFactor; // center the image if (widthFactor > heightFactor) { thumbnailPoint.y = (targetHeight - scaledHeight) * 0.5; } else if (widthFactor < heightFactor) { thumbnailPoint.x = (targetWidth - scaledWidth) * 0.5; } } CGImageRef imageRef = [sourceImage CGImage]; CGBitmapInfo bitmapInfo = CGImageGetBitmapInfo(imageRef); CGColorSpaceRef colorSpaceInfo = CGImageGetColorSpace(imageRef); if (bitmapInfo == kCGImageAlphaNone) { bitmapInfo = kCGImageAlphaNoneSkipLast; } CGContextRef bitmap; if (sourceImage.imageOrientation == UIImageOrientationUp || sourceImage.imageOrientation == UIImageOrientationDown) { bitmap = CGBitmapContextCreate(NULL, targetWidth, targetHeight, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo); } else { bitmap = CGBitmapContextCreate(NULL, targetHeight, targetWidth, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo); } // In the right or left cases, we need to switch scaledWidth and scaledHeight, // and also the thumbnail point if (sourceImage.imageOrientation == UIImageOrientationLeft) { thumbnailPoint = CGPointMake(thumbnailPoint.y, thumbnailPoint.x); CGFloat oldScaledWidth = scaledWidth; scaledWidth = scaledHeight; scaledHeight = oldScaledWidth; CGContextRotateCTM (bitmap, radians(90)); CGContextTranslateCTM (bitmap, 0, -targetHeight); } else if (sourceImage.imageOrientation == UIImageOrientationRight) { thumbnailPoint = CGPointMake(thumbnailPoint.y, thumbnailPoint.x); CGFloat oldScaledWidth = scaledWidth; scaledWidth = scaledHeight; scaledHeight = oldScaledWidth; CGContextRotateCTM (bitmap, radians(-90)); CGContextTranslateCTM (bitmap, -targetWidth, 0); } else if (sourceImage.imageOrientation == UIImageOrientationUp) { // NOTHING } else if (sourceImage.imageOrientation == UIImageOrientationDown) { CGContextTranslateCTM (bitmap, targetWidth, targetHeight); CGContextRotateCTM (bitmap, radians(-180.)); } CGContextDrawImage(bitmap, CGRectMake(thumbnailPoint.x, thumbnailPoint.y, scaledWidth, scaledHeight), imageRef); CGImageRef ref = CGBitmapContextCreateImage(bitmap); UIImage* newImage = [UIImage imageWithCGImage:ref]; CGContextRelease(bitmap); CGImageRelease(ref); return newImage; } The method we employ here is to create a bitmap with the desired size, but draw an image that is actually larger, thus maintaining the aspect ratio. So We've Got Our Scaled Images - How Do I Save Them To Disk? This is pretty simple. Remember that we want to save a compressed version to disk, and not the uncompressed pixels. Apple provides two functions that help us with this (documentation is here): NSData* UIImagePNGRepresentation(UIImage *image); NSData* UIImageJPEGRepresentation (UIImage *image, CGFloat compressionQuality); And if you want to use them, you'd do something like: UIImage* myThumbnail = ...; // Get some image NSData* imageData = UIImagePNGRepresentation(myThumbnail); Now we're ready to save it to disk, which is the final step (say into the documents directory): // Give a name to the file NSString* imageName = @"MyImage.png"; // Now, we have to find the documents directory so we can save it // Note that you might want to save it elsewhere, like the cache directory, // or something similar. NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString* documentsDirectory = [paths objectAtIndex:0]; // Now we get the full path to the file NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName]; // and then we write it out [imageData writeToFile:fullPathToFile atomically:NO]; You would repeat this for every version of the image you have. How Do I Load These Images Back Into Memory? Just look at the various UIImage initialization methods, such as +imageWithContentsOfFile: in the Apple documentation.

Bulk inserting best way to about it? + Helping me understand fully what I found so far

- by chobo2

Hi So I saw this post here and read it and it seems like bulk copy might be the way to go. http://stackoverflow.com/questions/682015/whats-the-best-way-to-bulk-database-inserts-from-c I still have some questions and want to know how things actually work. So I found 2 tutorials. http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx First way uses 2 ado.net 2.0 features. BulkInsert and BulkCopy. the second one uses linq to sql and OpenXML. This sort of appeals to me as I am using linq to sql already and prefer it over ado.net. However as one person pointed out in the posts what he just going around the issue at the cost of performance( nothing wrong with that in my opinion) First I will talk about the 2 ways in the first tutorial I am using VS2010 Express, .net 4.0, MVC 2.0, SQl Server 2005 Is ado.net 2.0 the most current version? Based on the technology I am using, is there some updates to what I am going to show that would improve it somehow? Is there any thing that these tutorial left out that I should know about? BulkInsert I am using this table for all the examples. CREATE TABLE [dbo].[TBL_TEST_TEST] ( ID INT IDENTITY(1,1) PRIMARY KEY, [NAME] [varchar](50) ) SP Code USE [Test] GO /****** Object: StoredProcedure [dbo].[sp_BatchInsert] Script Date: 05/19/2010 15:12:47 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[sp_BatchInsert] (@Name VARCHAR(50) ) AS BEGIN INSERT INTO TBL_TEST_TEST VALUES (@Name); END C# Code /// <summary> /// Another ado.net 2.0 way that uses a stored procedure to do a bulk insert. /// Seems slower then "BatchBulkCopy" way and it crashes when you try to insert 500,000 records in one go. /// http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 /// </summary> private static void BatchInsert() { // Get the DataTable with Rows State as RowState.Added DataTable dtInsertRows = GetDataTable(); SqlConnection connection = new SqlConnection(connectionString); SqlCommand command = new SqlCommand("sp_BatchInsert", connection); command.CommandType = CommandType.StoredProcedure; command.UpdatedRowSource = UpdateRowSource.None; // Set the Parameter with appropriate Source Column Name command.Parameters.Add("@Name", SqlDbType.VarChar, 50, dtInsertRows.Columns[0].ColumnName); SqlDataAdapter adpt = new SqlDataAdapter(); adpt.InsertCommand = command; // Specify the number of records to be Inserted/Updated in one go. Default is 1. adpt.UpdateBatchSize = 1000; connection.Open(); int recordsInserted = adpt.Update(dtInsertRows); connection.Close(); } So first thing is the batch size. Why would you set a batch size to anything but the number of records you are sending? Like I am sending 500,000 records so I did a Batch size of 500,000. Next why does it crash when I do this? If I set it to 1000 for batch size it works just fine. System.Data.SqlClient.SqlException was unhandled Message="A transport-level error has occurred when sending the request to the server.

Next I looked at bulkcopy /// <summary> /// An ado.net 2.0 way to mass insert records. This seems to be the fastest. /// http://www.codeproject.com/KB/cs/MultipleInsertsIn1dbTrip.aspx#_Toc196622241 /// </summary> private static void BatchBulkCopy() { // Get the DataTable DataTable dtInsertRows = GetDataTable(); using (SqlBulkCopy sbc = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.KeepIdentity)) { sbc.DestinationTableName = "TBL_TEST_TEST"; // Number of records to be processed in one go sbc.BatchSize = 500000; // Map the Source Column from DataTabel to the Destination Columns in SQL Server 2005 Person Table // sbc.ColumnMappings.Add("ID", "ID"); sbc.ColumnMappings.Add("NAME", "NAME"); // Number of records after which client has to be notified about its status sbc.NotifyAfter = dtInsertRows.Rows.Count; // Event that gets fired when NotifyAfter number of records are processed. sbc.SqlRowsCopied += new SqlRowsCopiedEventHandler(sbc_SqlRowsCopied); // Finally write to server sbc.WriteToServer(dtInsertRows); sbc.Close(); } } This one seemed to go really fast and did not even need a SP( can you use SP with bulk copy? If you can would it be better?) BatchCopy had no problem with a 500,000 batch size.So again why make it smaller then the number of records you want to send? I found that with BatchCopy and 500,000 batch size it took only 5 seconds to complete. I then tried with a batch size of 1,000 and it only took 8 seconds. So much faster then the bulkinsert one above. Now I tried the other tutorial. USE [Test] GO /****** Object: StoredProcedure [dbo].[spTEST_InsertXMLTEST_TEST] Script Date: 05/19/2010 15:39:03 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc C# code. /// <summary> /// This is using linq to sql to make the table objects. /// It is then serailzed to to an xml document and sent to a stored proedure /// that then does a bulk insert(I think with OpenXML) /// http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx /// </summary> private static void LinqInsertXMLBatch() { using (TestDataContext db = new TestDataContext()) { TBL_TEST_TEST[] testRecords = new TBL_TEST_TEST[500000]; for (int count = 0; count < 500000; count++) { TBL_TEST_TEST testRecord = new TBL_TEST_TEST(); testRecord.NAME = "Name : " + count; testRecords[count] = testRecord; } StringBuilder sBuilder = new StringBuilder(); System.IO.StringWriter sWriter = new System.IO.StringWriter(sBuilder); XmlSerializer serializer = new XmlSerializer(typeof(TBL_TEST_TEST[])); serializer.Serialize(sWriter, testRecords); db.insertTestData(sBuilder.ToString()); } } So I like this because I get to use objects even though it is kinda redundant. I don't get how the SP works. Like I don't get the whole thing. I don't know if OPENXML has some batch insert under the hood but I do not even know how to take this example SP and change it to fit my tables since like I said I don't know what is going on. I also don't know what would happen if the object you have more tables in it. Like say I have a ProductName table what has a relationship to a Product table or something like that. In linq to sql you could get the product name object and make changes to the Product table in that same object. So I am not sure how to take that into account. I am not sure if I would have to do separate inserts or what. The time was pretty good for 500,000 records it took 52 seconds The last way of course was just using linq to do it all and it was pretty bad. /// <summary> /// This is using linq to sql to to insert lots of records. /// This way is slow as it uses no mass insert. /// Only tried to insert 50,000 records as I did not want to sit around till it did 500,000 records. /// http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx /// </summary> private static void LinqInsertAll() { using (TestDataContext db = new TestDataContext()) { db.CommandTimeout = 600; for (int count = 0; count < 50000; count++) { TBL_TEST_TEST testRecord = new TBL_TEST_TEST(); testRecord.NAME = "Name : " + count; db.TBL_TEST_TESTs.InsertOnSubmit(testRecord); } db.SubmitChanges(); } } I did only 50,000 records and that took over a minute to do. So I really narrowed it done to the linq to sql bulk insert way or bulk copy. I am just not sure how to do it when you have relationship for either way. I am not sure how they both stand up when doing updates instead of inserts as I have not gotten around to try it yet. I don't think I will ever need to insert/update more than 50,000 records at one type but at the same time I know I will have to do validation on records before inserting so that will slow it down and that sort of makes linq to sql nicer as your got objects especially if your first parsing data from a xml file before you insert into the database.

Content Box is a Little Off in IE9 ... How to Fix?

- by Kelsey Nealon

Hi there! I have a website at www.thetotempole.ca and when viewed in IE9... My websites content box (The green wooden backgrounded box with content inside) is moved slightly over to the left making a space between the actual container and the content box... Is there anyway I can fix this without harming any of the other browsers? Thanks!

Problems Allocating Objects of Derived Class Where Base Class has Abstract Virtual Functions

- by user1743901

I am trying to get this Zombie/Human agent based simulation running, but I am having problems with these derived classes (Human and Zombie) who have parent class "Creature". I have 3 virtual functions declared in "Creature" and all three of these are re-declared AND DEFINED in both "Human" and "Zombie".

C++/boost generator module, feedback/critic please

- by aaa

hello. I wrote this generator, and I think to submit to boost people. Can you give me some feedback about it it basically allows to collapse multidimensional loops to flat multi-index queue. Loop can be boost lambda expressions. Main reason for doing this is to make parallel loops easier and separate algorithm from controlling structure (my fieldwork is computational chemistry where deep loops are common) 1 #ifndef _GENERATOR_HPP_ 2 #define _GENERATOR_HPP_ 3 4 #include <boost/array.hpp> 5 #include <boost/lambda/lambda.hpp> 6 #include <boost/noncopyable.hpp> 7 8 #include <boost/mpl/bool.hpp> 9 #include <boost/mpl/int.hpp> 10 #include <boost/mpl/for_each.hpp> 11 #include <boost/mpl/range_c.hpp> 12 #include <boost/mpl/vector.hpp> 13 #include <boost/mpl/transform.hpp> 14 #include <boost/mpl/erase.hpp> 15 16 #include <boost/fusion/include/vector.hpp> 17 #include <boost/fusion/include/for_each.hpp> 18 #include <boost/fusion/include/at_c.hpp> 19 #include <boost/fusion/mpl.hpp> 20 #include <boost/fusion/include/as_vector.hpp> 21 22 #include <memory> 23 24 /** 25 for loop generator which can use lambda expressions. 26 27 For example: 28 @code 29 using namespace generator;

Confused Why I am getting C1010 error?

- by bluepixel

I have three files: Main, slist.h and slist.cpp can be seen at http://forums.devarticles.com/c-c-help-52/confused-why-i-am-getting-c2143-and-c1010-error-259574.html I'm trying to make a program where main reads the list of student names from a file (roster.txt) and inserts all the names in a list in ascending order. This is the full class roster list (notCheckedIN). From here I will read all students who have come to write the exams, each checkin will transfer their name to another list (in ascending order) called present.

Null reading in stream images? Unable to start activity ComponentInfo

- by lasmith

I have reviewed a lot of similar questions regarding not being able to launch an activity but they don't seem to quite match my problem. I am working on a simple black jack game but its force quitting. I suspect there is a problem with loading up the card png images I have. Stepping through the debugger it crashes right while in the resetGame() function. I'm sure I am doing something dumb.

Simple Self Join Query Bad Performance

Could anyone advice on how do I improve the performance of the following query. Note, the problem seems to be caused by where clause. Data (table contains a huge set of rows - 500K+, the set of parameters it's called with assums the return of 2-5K records per query, which takes 8-10 minutes currently): USE [SomeDb] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[Data]( [x] [money] NOT NULL, [y] [money] NOT NULL, CONSTRAINT [PK_Data] PRIMARY KEY CLUSTERED ( [x] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO The Query select top 10000 s.x as sx, e.x as ex, s.y as sy, e.y as ey, e.y - s.y as y_delta, e.x - s.x as x_delta from Data s inner join Data e on e.x > s.x and e.x - s.x between xFrom and xTo --where e.y - s.y > @yDelta -- when uncommented causes a huge delay Update 1 - Execution Plan <?xml version="1.0" encoding="utf-16"?> <ShowPlanXML xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="1.2" Build="11.0.2100.60" xmlns="http://schemas.microsoft.com/sqlserver/2004/07/showplan"> <BatchSequence> <Batch> <Statements> <StmtSimple StatementCompId="1" StatementEstRows="100" StatementId="1" StatementOptmLevel="FULL" StatementOptmEarlyAbortReason="GoodEnoughPlanFound" StatementSubTreeCost="0.0263655" StatementText="select top 100

Uncompiled WCF on IIS7: The type could not be found

- by Jimmy

Hello, I've been trying to follow this tutorial for deploying a WCF sample to IIS . I can't get it to work. This is a hosted site, but I do have IIS Manager access to the server. However, in step 2 of the tutorial, I can't "create a new IIS application that is physically located in this application directory". I can't seem to find a menu item, context menu item, or what not to create a new application. I've been right-clicking everywhere like crazy and still can't figure out how to create a new app. I suppose that's probably the root issue, but I tried a few other things (described below) just in case that actually is not the issue. This is "deployed" at http://test.com.cws1.my-hosting-panel.com/IISHostedCalcService/Service.svc . The error says: The type 'Microsoft.ServiceModel.Samples.CalculatorService', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found. I also tried to create a virtual dir (IISHostedCalc) in dotnetpanel that points to IISHostedCalcService . When I navigate to http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc , then there is a different error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. As per the tutorial, there was no compiling involved; I just dropped the files on the server as follow inside the folder IISHostedCalcService: service.svc Web.config Service.cs service.svc contains: <%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService"%> (I tried with quotes around the c# attribute, as this looks a little strange without quotes, but it made no difference) Web.config contains: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="Microsoft.ServiceModel.Samples.CalculatorService">  <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" />  <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Service.cs contains: using System; using System.ServiceModel; namespace Microsoft.ServiceModel.Samples { [ServiceContract] public interface ICalculator { [OperationContract] double Add(double n1, double n2); [OperationContract] double Subtract(double n1, double n2); [OperationContract] double Multiply(double n1, double n2); [OperationContract] double Divide(double n1, double n2); } public class CalculatorService : ICalculator { public double Add(double n1, double n2) { return n1 + n2; } public double Subtract(double n1, double n2) { return n1 - n2; } public double Multiply(double n1, double n2) { return n1 * n2; } public double Divide(double n1, double n2) { return n1 / n2; } } }

How to Edit or Add a New Row in jqGrid

- by Paul

My jqGrid that does a great job of pulling data from my database, but I'm having trouble understanding how the Add New Row functionality works. Right now, I'm able to edit inline data, but I'm not able to create a new row using the Modal Box. I'm missing that extra logic that says, "If this is a new row, post this to the server side URL" instead of modifying existing data. (Right now, hitting Submit only clears the form and reloads the grid data.) The documentation states that Add New Row is: jQuery("#editgrid").jqGrid('editGridRow',"new",{height:280,reloadAfterSubmit:false}); but I'm not sure how to use that correctly. I've spent alot of time studying the Demos, but they seem to all use an external button to fire the new row command, rather than using the Modal Form, which I want to do. My complete code is here: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>jqGrid</title> <link rel="stylesheet" type="text/css" media="screen" href="../css/ui-lightness/jquery-ui-1.7.2.custom.css" /> <link rel="stylesheet" type="text/css" media="screen" href="../css/ui.jqgrid.css" /> <script src="jquery-1.3.2.min.js" type="text/javascript"></script> <script src="../js/i18n/grid.locale-en.js" type="text/javascript"></script> <script src="jquery.jqGrid.min.js" type="text/javascript"></script> </head> <body> <h2>My Grid Data</h2> <table id="list" class="scroll"></table> <div id="pager" class="scroll c1"></div> <script type="text/javascript"> var lastSelectedId; jQuery('#list').jqGrid({ url:'grid.php', datatype: 'json', mtype: 'POST', colNames:['ID','Name', 'Price', 'Promotion'], colModel:[ {name:'product_id',index:'product_id', width:25,editable:false}, {name:'name',index:'name', width:50,editable:true, edittype:'text',editoptions:{size:30,maxlength:50}}, {name:'price',index:'price', width:50, align:'right',formatter:'currency', editable:true}, {name:'on_promotion',index:'on_promotion', width:50, formatter:'checkbox',editable:true, edittype:'checkbox'}], rowNum:10, rowList:[5,10,20,30], pager: $('#pager'), sortname: 'product_id', viewrecords: true, sortorder: "desc", caption:"Database", width:500, height:150, onSelectRow: function(id){ if(id && id!==lastSelectedId){ $('#list').restoreRow(lastSelectedId); $('#list').editRow(id,true,null,onSaveSuccess); lastSelectedId=id; }}, editurl:'grid.php?action=save'}) .jqGrid('navGrid','#pager', {refreshicon: 'ui-icon-refresh',view:true}, {height:280,reloadAfterSubmit:true}, {height:280,reloadAfterSubmit:true}, {reloadAfterSubmit:true}) .jqGrid('editGridRow',"new",{height:280,reloadAfterSubmit:false}); function onSaveSuccess(xhr) {response = xhr.responseText; if(response == 1) return true; return false;} </script></body></html> If it makes it easier, I'd be willing to scrap the inline editing functionality and do editing and posting via modal boxes. Any help would be greatly appreciated.

Sharepoint web services -- The HTTP request is unauthorized with client authentication scheme 'Ntlm'

- by Pandincus

I know there's a lot of questions on SO similar to this, but I couldn't find one for this particular issue. A couple of points, first: I have no control over our Sharepoint server. I cannot tweak any IIS settings. I believe our IIS server version is IIS 7.0. Our Sharepoint Server is anticipating requests via NTLM. Our Sharepoint Server is on the same domain as my client computer. I am using .NET Framework 3.5, Visual Studio 2008 I am trying to write a simple console app to manipulate Sharepoint data using Sharepoint Web Services. I have added the Service Reference, and the following is my app.config: <system.serviceModel> <bindings> <basicHttpBinding> <binding name="ListsSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="Transport"> <transport clientCredentialType="Ntlm" proxyCredentialType="Ntlm" /> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="https://subdomain.companysite.com/subsite/_vti_bin/Lists.asmx" binding="basicHttpBinding" bindingConfiguration="ListsSoap" contract="ServiceReference1.ListsSoap" name="ListsSoap" /> </client> </system.serviceModel> This is my code: static void Main(string[] args) { using (var client = new ListsSoapClient()) { client.ClientCredentials.Windows.ClientCredential = new NetworkCredential("username", "password", "domain"); client.GetListCollection(); } } When I call GetListCollection(), the following MessageSecurityException gets thrown: The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'NTLM'. With an inner WebException: "The remote server returned an error: (401) Unauthorized." I've tried various bindings and various code tweaks to try to authenticate properly, but to no avail. I'll list those below. I've tried the following steps: Using a native Win32 Impersonator before creating the client using (new Impersonator.Impersonator("username", "password", "domain")) using (var client = new ListsSoapClient()) { client.ClientCredentials.Windows.ClientCredential = new NetworkCredential("dpincas", "password", "domain"); client.GetListCollection(); } This produced the same error message. Setting TokenImpersonationLevel for my client credentials using (var client = new ListsSoapClient()) { client.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation; client.GetListCollection(); } This produced the same error message. Using security mode=TransportCredentialOnly <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm" /> </security> This resulted in a different error message: The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via However, I need to use https, so I cannot change my URI scheme. I've tried some other combinations that I can't remember, but I'll post them when I do. I'm really at wits end here. I see a lot of links on Google that say "switch to Kerberos", but my server seems to only be accepting NTLM, not "Negotiate" (as it would say if it was looking for Kerberos), so that is unfortunately not an option. Any help out there, folks?

Calling a WCF service from another WCF service

- by ultraman69

Hi ! I have a WCF service hosted on a windows service on my Server1. It also has IIS on this machine. I call the service from a web app and it works fine. But within this service, I have to call another WCF sevice (also hosted on a windows service) located on Server2. The security credentials are set to "Message" and "Username". I have an error like "SOAP protcol negociation failed". It's a problem with my server certificate public key that doesn't seem to be recognise. However, if I call the service on the Server2 from Server1 in a console app, it works fine. I followed this tutorial to set up my certificates : http://www.codeproject.com/KB/WCF/wcf_certificates.aspx Here's the config file from my service on Server1 that tries to call the second one : <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ITraitement" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <client> <endpoint address="http://Server2:8000/servicemodelsamples/service" behaviorConfiguration="myClientBehavior" binding="wsHttpBinding" bindingConfiguration="MybindingCon" contract="Microsoft.ServiceModel.Samples.ICalculator" name=""> <identity> <dns value="ODWCertificatServeur" /> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <clientCertificate findValue="MachineServiceTraitement" x509FindType="FindBySubjectName" storeLocation="LocalMachine" storeName="My" /> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> And here's the config file from the web app that calls the service on Server1 : <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_ITraitement" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:8020/ServiceTraitementPC" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ITraitement" contract="ITraitement" name="WSHttpBinding_ITraitement"> </endpoint> </client> Any idea why it works if if I call it in a console app and not from my service ? Maybe it has something to do with the certificateValidationMode="ChainTrust" ?

Need help with Android TableLayout alignment

- by Ben L.

I'm trying to build a calculator layout using TableLayout, but the last two rows aren't aligning with the rest of the layout. Is there something wrong with my layout XML? What I'm trying to do would be easier to accomplish in HTML (<td> with colspan or rowspan), so should I try converting this into a WebView? Code is as follows: (Screenshot) <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" /> <TableLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:stretchColumns="*"> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <Button android:id="@+id/Button08" android:textSize="16pt" android:text="^" android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="wrap_content" /> <Button android:id="@+id/Button09" android:text="÷" android:textSize="16pt" android:layout_height="fill_parent" android:layout_weight="1" android:layout_width="wrap_content" /> <Button android:id="@+id/Button10" android:text="×" android:textSize="16pt" android:layout_height="fill_parent" android:layout_weight="1" android:layout_width="wrap_content" /> <Button android:id="@+id/Button11" android:textSize="16pt" android:text="-" android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="wrap_content" /> </TableRow> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="2"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1"> <Button android:id="@+id/Button01" android:text="7" android:textSize="16pt" android:layout_weight="1" android:layout_height="wrap_content" android:layout_width="fill_parent" /> <Button android:layout_height="wrap_content" android:textSize="16pt" android:text="4" android:id="@+id/Button05" android:layout_weight="1" android:layout_width="fill_parent" /> </LinearLayout> <LinearLayout android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:layout_width="fill_parent"> <Button android:id="@+id/Button02" android:layout_height="wrap_content" android:text="8" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" /> <Button android:layout_height="wrap_content" android:textSize="16pt" android:text="5" android:id="@+id/Button06" android:layout_weight="1" android:layout_width="fill_parent" /> </LinearLayout> <LinearLayout android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:layout_width="fill_parent"> <Button android:id="@+id/Button03" android:text="9" android:textSize="16pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" /> <Button android:textSize="16pt" android:text="6" android:id="@+id/Button07" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" /> </LinearLayout> <Button android:id="@+id/Button04" android:text="+" android:textSize="16pt" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1" /> </TableRow> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="2"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="2"> <LinearLayout android:layout_weight="1" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/Button02" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="1" /> <Button android:textSize="16pt" android:id="@+id/Button06" android:layout_weight="1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="2" /> </LinearLayout> <Button android:id="@+id/Button01" android:layout_height="wrap_content" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" android:text="0" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1"> <Button android:id="@+id/Button03" android:textSize="16pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="3" /> <Button android:textSize="16pt" android:id="@+id/Button07" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="." /> </LinearLayout> <Button android:id="@+id/Button04" android:textSize="16pt" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1" android:text="=" /> </TableRow> </TableLayout> </LinearLayout>

Flex - Typed ArrayCollection as Horizontallist's dataprovider

- by BS_C3

Hi community! I have an ArrayCollection of objects. I'm passing this array to a horizontallist as a dataprovider and I'm using a custom itemRenderer. When executing the application, the horizontallist is displaying [object CustomClass][object CustomClass][object CustomClass][object CustomClass] I've tried casting each object in the itemrenderer as following: <mx:Label text="{(data as CustomClass).label1}"/> But it's not working... Thanks for any help you can provide. Regards, BS_C3 Edit - 09 March 2010 Let's go for some more code =) <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Component id="Item"> <mx:VBox width="180"> <mx:HBox width="100%"> <mx:Spacer width="100%"/> <mx:Button label="x"/> </mx:HBox> <mx:Image id="thumbnail"/> <mx:Label width="100%" horizontalCenter="0" text="Collection"/> <mx:HBox width="100%"> <mx:Label width="100" text="GIA"/> <mx:Label text="{data.charg_st}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Finger Size"/> <mx:Label text="xxxxxx"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Carat"/> <mx:Label text="{data.carats}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Color"/> <mx:Label text="{data.color}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Clarity"/> <mx:Label text="{data.clarity}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Shop"/> <mx:Label text="{data.lgort_fp}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Resizing"/> <mx:Label text="{data.resizing}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Price Excl. VAT"/> <mx:Label text="{data.net_price_fp}"/> </mx:HBox> </mx:VBox> </mx:Component> <mx:HorizontalList dataProvider="{GlobalData.instance.tray}" columnCount="4" rowCount="1" horizontalScrollPolicy="off" itemRenderer="{Item}" /> </mx:Canvas> FYI, the horizonalList dataprovider is an ArrayCollection of objects. Now, the horizontallist is displaying empty items... with the correct width... The arraycollection is not empty (I'm using an alert on the click event on an item, and I do retrieve the expected data). Hope this will help _< Regards, BS_C3

Set the JAXB context factory initialization class to be used

- by user1902288

I have updated our projects (Java EE based running on Websphere 8.5) to use a new release of a company internal framework (and Ejb 3.x deployment descriptors rather than the 2.x ones). Since then my integration Tests fail with the following exception: [java.lang.ClassNotFoundException: com.ibm.xml.xlxp2.jaxb.JAXBContextFactory] I can build the application with the previous framework release and everything works fine. While debugging i noticed that within the ContextFinder (javax.xml.bind) there are two different behaviours: Previous Version (Everything works just fine): None of the different places brings up a factory class so the default factory class gets loaded which is com.sun.xml.internal.bind.v2.ContextFactory (defined as String constant within the class). Upgraded Version (ClassNotFound): There is a resource "META-INF/services/javax.xml.bind.JAXBContext" beeing loaded successfully and the first line read makes the ContextFinder attempt to load "com.ibm.xml.xlxp2.jaxb.JAXBContextFactory" which causes the error. I now have two questions: What sort is that resource? Because inside our EAR there is two WARs and none of those two contains a folder services in its META-INF directory. Where could that value be from otherwise? Because a filediff showed me no new or changed properties files. No need to say i am going to read all about the JAXB configuration possibilities but if you have first insights on what could have gone wrong or help me out with that resource (is it a real file i have to look for?) id appreciate a lot. Many Thanks! EDIT (according to comments Input/Questions): Out of curiosity, does your framework include JAXB JARs? Did the old version of your framework include jaxb.properties? Indeed (i am a bit surprised) the framework has a customized eclipselink-2.4.1-.jar inside the EAR that includes both a JAXB implementation and a jaxb.properties file that shows the following entry in both versions (the one that finds the factory as well as in the one that throws the exception): javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory I think this is has nothing to do with the current issue since the jar stayed exactly the same in both EARs (the one that runs/ the one with the expection) It's also not clear to me why the old version of the framework was ever selecting the com.sun implementation There is a class javax.xml.bind.ContextFinder which is responsible for initializing the JAXBContextFactory. This class searches various placess for the existance of a jaxb.properties file or a "javax.xml.bind.JAXBContext" resource. If ALL of those places dont show up which Context Factory to use there is a deault factory loaded which is hardcoded in the class itself: private static final String PLATFORM_DEFAULT_FACTORY_CLASS = "com.sun.xml.internal.bind.v2.ContextFactory"; Now back to my problem: Building with the previous version of the framework (and EJB 2.x deployment descriptors) everything works fine). While debugging i can see that there is no configuration found and thatfore above mentioned default factory is loaded. Building with the new version of the framework (and EJB 3.x deployment descriptors so i can deploy) ONLY A TESTCASE fails but the rest of the functionality works (like i can send requests to our webservice and they dont trigger any errors). While debugging i can see that there is a configuration found. This resource is named "META-INF/services/javax.xml.bind.JAXBContext". Here are the most important lines of how this resource leads to the attempt to load 'com.ibm.xml.xlxp2.jaxb.JAXBContextFactory' which then throws the ClassNotFoundException. This is simplified source of the mentioned javax.xml.bind.ContextFinder class: URL resourceURL = ClassLoader.getSystemResource("META-INF/services/javax.xml.bind.JAXBContext"); BufferedReader r = new BufferedReader(new InputStreamReader(resourceURL.openStream(), "UTF-8")); String factoryClassName = r.readLine().trim(); The field factoryClassName now has the value 'com.ibm.xml.xlxp2.jaxb.JAXBContextFactory' (The day i understand how to format source code on stackoverflow will be my biggest step ahead.... sorry for the formatting after 20 mins it still looks the same :() Because this has become a super lager question i will also add a bounty :)

Setting int more than once causes crash

- by JulianB

I'm doing a CABasicAnimation and getting the value from a nested NSMutableArray. Everything is great the first time it runs but crashes when called again either with custom functions or viewDidLoad. I've isolated it down to this line int int1 = [[[locationsArray objectAtIndex:0] objectAtIndex:0 ]integerValue] ; I assume it's to do with int not being a pointer but I'm lost as have to get the value without crashing the second time around Process: CEO Report 2011 [61880] Path: /Users/julian/Library/Application Support/iPhone Simulator/4.2/Applications/03CFB7BC-0722-4CA0-9E7D-39772AEEF444/CEO Report 2011.app/CEO Report 2011 Identifier: CEO Report 2011 Version: ???
