  • ASP.NET MVC Using Castle Windsor IoC

    - by Mad Halfling
    I have an app, modelled on the one from Apress Pro ASP.NET MVC that uses castle windsor's IoC to instantiate the controllers with their respective repositories, and this is working fine e.g. public class ItemController : Controller { private IItemsRepository itemsRepository; public ItemController(IItemsRepository windsorItemsRepository) { this.itemsRepository = windsorItemsRepository; } with using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using Castle.Windsor; using Castle.Windsor.Configuration.Interpreters; using Castle.Core.Resource; using System.Reflection; using Castle.Core; namespace WebUI { public class WindsorControllerFactory : DefaultControllerFactory { WindsorContainer container; // The constructor: // 1. Sets up a new IoC container // 2. Registers all components specified in web.config // 3. Registers all controller types as components public WindsorControllerFactory() { // Instantiate a container, taking configuration from web.config container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle"))); // Also register all the controller types as transient var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach (Type t in controllerTypes) container.AddComponentWithLifestyle(t.FullName, t, LifestyleType.Transient); } // Constructs the controller instance needed to service each request protected override IController GetControllerInstance(Type controllerType) { return (IController)container.Resolve(controllerType); } } } controlling the controller creation. I sometimes need to create other repository instances within controllers, to pick up data from other places, can I do this using the CW IoC, if so then how? I have been playing around with the creation of new controller classes, as they should auto-register with my existing code (if I can get this working, I can register them properly later) but when I try to instantiate them there is an obvious objection as I can't supply a repos class for the constructor (I was pretty sure that was the wrong way to go about it anyway). Any help (especially examples) would be much appreciated. Cheers MH

  • Removing "Using temporary; Using filesort" from this MySQL select+join+group by query

    - by claytontstanley
    I have the following query: select t.Chunk as LeftChunk, t.ChunkHash as LeftChunkHash, q.Chunk as RightChunk, q.ChunkHash as RightChunkHash, count(t.ChunkHash) as ChunkCount from chunksubset as t join chunksubset as q on t.ID = q.ID group by LeftChunkHash, RightChunkHash And the following explain table: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE subsets ref PRIMARY,IDIndex,SubsetIndex SubsetIndex 767 const 522014 "Using where; Using temporary; Using filesort" 1 SIMPLE subsets eq_ref PRIMARY,IDIndex,SubsetIndex PRIMARY 771 sotero.subsets.Id,const 1 "Using where; Using index" 1 SIMPLE c ref IDIndex IDIndex 4 sotero.subsets.Id 12 "Using where" 1 SIMPLE c ref IDIndex IDIndex 4 sotero.subsets.Id 12 note the "using temporary; using filesort". When this query is run, I quickly run out of RAM (presumably b/c of the temp table), and then the HDD kicks in, and the query slows to a halt. I thought it might be an index issue, so I started adding a few that sort of made sense: Table Non_unique Key_name Seq_in_index Column_name Collation Cardinality Sub_part Packed Null Index_type Comment Index_comment chunks 0 PRIMARY 1 ChunkId A 17796190 NULL NULL BTREE chunks 1 ChunkHashIndex 1 ChunkHash A 243783 NULL NULL BTREE chunks 1 IDIndex 1 Id A 1483015 NULL NULL BTREE chunks 1 ChunkIndex 1 Chunk A 243783 NULL NULL BTREE chunks 1 ChunkTypeIndex 1 ChunkType A 2 NULL NULL BTREE chunks 1 chunkHashByChunkIDIndex 1 ChunkHash A 243783 NULL NULL BTREE chunks 1 chunkHashByChunkIDIndex 2 ChunkId A 17796190 NULL NULL BTREE chunks 1 chunkHashByChunkTypeIndex 1 ChunkHash A 243783 NULL NULL BTREE chunks 1 chunkHashByChunkTypeIndex 2 ChunkType A 261708 NULL NULL BTREE chunks 1 chunkHashByIDIndex 1 ChunkHash A 243783 NULL NULL BTREE chunks 1 chunkHashByIDIndex 2 Id A 17796190 NULL NULL BTREE But still using the temporary table. The db engine is MyISAM. How can I get rid of the using temporary; using filesort in this query? Just changing to InnoDB w/o explaining the underlying cause is not a particularly satisfying answer. Besides, if the solution is to just add the proper index, then that's much easier than migrating to another db engine.

  • Apache SSO through Kerberos using Machine Account

    - by watkipet
    I'm attempting to get Apache on Ubuntu 12.04 to authenticate users via Kerberos SSO to a Windows 2008 Active Directory server. Here are a few things that make my situation different: I don't have administrative access to the Windows Server (nor will I ever have access). I also cannot have any changes to the server made on my behalf. I've joined Ubuntu server to the Active Directory using PBIS open. Users can log into the Ubuntu server using their AD credentials. kinit also works fine for each user. Since I can't change AD (except for adding new machines and SPNs), I cannot add a service account for Apache on Ubuntu. Since I can't add I service account, I have to use the machine keytab (/etc/krb5.keytab), or at least use the machine password in another keytab. Right now I'm using the machine keytab and giving Apache readonly access (bad idea, I know). I've already added the SPN using net ads keytab add HTTP -U Since I'm using Ubuntu 12.04, the only encoding types that get added during "net ads keytab add" are arcfour-hmac, des-cbc-crc, and des-cbc-md5. PBIS adds the AES encoding types to the host and cifs principals when it joins the domain, but I have yet to get "net ads keytab add" to do this. ktpass and setspn are out of the question because of #1 above. I've configured (for Kerberos SSO) and tested both IE 8 Firefox. I'm using the following configuration in my Apache site config: <Location /secured> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms DOMAIN.COM Krb5KeyTab /etc/krb5.keytab KrbLocalUserMapping On require valid-user </Location> When Firefox tries to connect get the following in Apache's error.log (LogLevel debug): [Wed Oct 23 13:48:31 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 13:48:31 2013] [debug] mod_deflate.c(615): [client 192.168.0.2] Zlib: Compressed 477 to 322 : URL /secured [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(994): [client 192.168.0.2] Using HTTP/[email protected] as server principal for password verification [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(698): [client 192.168.0.2] Trying to get TGT for user [email protected] [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(609): [client 192.168.0.2] Trying to verify authenticity of KDC using principal HTTP/[email protected] [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(652): [client 192.168.0.2] krb5_rd_req() failed when verifying KDC [Wed Oct 23 13:48:37 2013] [error] [client 192.168.0.2] failed to verify krb5 credentials: Decrypt integrity check failed [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(1073): [client 192.168.0.2] kerb_authenticate_user_krb5pwd ret=401 user=(NULL) authtype=(NULL) [Wed Oct 23 13:48:37 2013] [debug] mod_deflate.c(615): [client 192.168.0.2] Zlib: Compressed 477 to 322 : URL /secured When IE 8 tries to connect I get: [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 14:03:30 2013] [debug] mod_deflate.c(615): [client 192.168.0.2] Zlib: Compressed 477 to 322 : URL /secured [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1240): [client 192.168.0.2] Acquiring creds for HTTP@apache_server [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1385): [client 192.168.0.2] Verifying client data using KRB5 GSS-API [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1401): [client 192.168.0.2] Client didn't delegate us their credential [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1420): [client 192.168.0.2] GSS-API token of length 9 bytes will be sent back [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1101): [client 192.168.0.2] GSS-API major_status:000d0000, minor_status:000186a5 [Wed Oct 23 14:03:30 2013] [error] [client 192.168.0.2] gss_accept_sec_context() failed: Unspecified GSS failure.

  • Is it possible to implement bitwise operators using integer arithmetic?

    - by Statement
    Hello World! I am facing a rather peculiar problem. I am working on a compiler for an architecture that doesn't support bitwise operations. However, it handles signed 16 bit integer arithmetics and I was wondering if it would be possible to implement bitwise operations using only: Addition (c = a + b) Subtraction (c = a - b) Division (c = a / b) Multiplication (c = a * b) Modulus (c = a % b) Minimum (c = min(a, b)) Maximum (c = max(a, b)) Comparisons (c = (a < b), c = (a == b), c = (a <= b), et.c.) Jumps (goto, for, et.c.) The bitwise operations I want to be able to support are: Or (c = a | b) And (c = a & b) Xor (c = a ^ b) Left Shift (c = a << b) Right Shift (c = a b) (All integers are signed so this is a problem) Signed Shift (c = a b) One's Complement (a = ~b) (Already found a solution, see below) Normally the problem is the other way around; how to achieve arithmetic optimizations using bitwise hacks. However not in this case. Writable memory is very scarce on this architecture, hence the need for bitwise operations. The bitwise functions themselves should not use a lot of temporary variables. However, constant read-only data & instruction memory is abundant. A side note here also is that jumps and branches are not expensive and all data is readily cached. Jumps cost half the cycles as arithmetic (including load/store) instructions do. On other words, all of the above supported functions cost twice the cycles of a single jump. Some thoughts that might help: I figured out that you can do one's complement (negate bits) with the following code: // Bitwise one's complement b = ~a; // Arithmetic one's complement b = -1 - a; I also remember the old shift hack when dividing with a power of two so the bitwise shift can be expressed as: // Bitwise left shift b = a << 4; // Arithmetic left shift b = a * 16; // 2^4 = 16 // Signed right shift b = a >>> 4; // Arithmetic right shift b = a / 16; For the rest of the bitwise operations I am slightly clueless. I wish the architects of this architecture would have supplied bit-operations. I would also like to know if there is a fast/easy way of computing the power of two (for shift operations) without using a memory data table. A naive solution would be to jump into a field of multiplications: b = 1; switch (a) { case 15: b = b * 2; case 14: b = b * 2; // ... exploting fallthrough (instruction memory is magnitudes larger) case 2: b = b * 2; case 1: b = b * 2; } Or a Set & Jump approach: switch (a) { case 15: b = 32768; break; case 14: b = 16384; break; // ... exploiting the fact that a jump is faster than one additional mul // at the cost of doubling the instruction memory footprint. case 2: b = 4; break; case 1: b = 2; break; }

  • How to create sprites, programatically without using prefabs?

    - by DemonSOCKET
    I have different types of images for different sprites. and i am not certain that how much different sprites(images) i will have to show. So, i gotta create the sprites and apply textures programatically at runtime. Now, I defiantly can't use prefabs because it will restrict me with the number of different sprites i can use. and also, changing texture on one sprite prefab instance in game, will change all the sprites prefab, that's not acceptable in my case. Is there a way i can create sprites without having to create static prefab ? where ever i looked for the solution every time i got the same answer "create a prefab", which is what can not be done in my case.

  • Drawing a rectangular prism using opengl

    - by BadSniper
    I'm trying to learn opengl. I did some code for building a rectangular prism. I don't want to draw back faces so I used glCullFace(GL_BACK), glEnable(GL_CULL_FACE);. But I keep getting back faces also when viewing from front and also sometimes when rotating sides are vanishing. Can someone point me in right direction? glPolygonMode(GL_FRONT,GL_LINE); // draw wireframe polygons glColor3f(0,1,0); // set color green glCullFace(GL_BACK); // don't draw back faces glEnable(GL_CULL_FACE); // don't draw back faces glTranslatef(-10, 1, 0); // position glBegin(GL_QUADS); // face 1 glVertex3f(0,-1,0); glVertex3f(0,-1,2); glVertex3f(2,-1,2); glVertex3f(2,-1,0); // face 2 glVertex3f(2,-1,2); glVertex3f(2,-1,0); glVertex3f(2,5,0); glVertex3f(2,5,2); // face 3 glVertex3f(0,5,0); glVertex3f(0,5,2); glVertex3f(2,5,2); glVertex3f(2,5,0); // face 4 glVertex3f(0,-1,2); glVertex3f(2,-1,2); glVertex3f(2,5,2); glVertex3f(0,5,2); // face 5 glVertex3f(0,-1,2); glVertex3f(0,-1,0); glVertex3f(0,5,0); glVertex3f(0,5,2); // face 6 glVertex3f(0,-1,0); glVertex3f(2,-1,0); glVertex3f(2,5,0); glVertex3f(0,5,0); glEnd();

  • Using gnome-boxes with Remote Desktop Connection

    - by lviggiani
    in the past I used to connect to my windows server from ubuntu with remmina (through rdp protocol). I've recently installed ubuntu gnome remix (12.10.1) and gnome-boxes and I'm wondering if I can do the same with gnome-boxes. I've tried creating a new item in gnome-boxes and entering as url "rdp://x.x.x.x" as I used to do in remmina bit it says that the rdp protocol is not supported. Unfortunatelly I cannot find any manual or documentation listing the supported protocol or giving instruction on how to connect to a remote desktop. Can someone help me please?

  • Configuring IIS7 404 page when using IIS7 urlrewrite module

    - by Peter
    I've got custom errors to work for .aspx page like: www.domain.com/whateverdfdgdfg.aspx But, when no .aspx url is requested, (like http://www.domain.com/hfdkfdh4545) it results in an error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I have this in my web.config: <customErrors mode="On" defaultRedirect="/error/1" redirectMode="ResponseRedirect"> <error statusCode="404" redirect="/404.aspx" /> </customErrors> 404.aspx exists, since the above DOES work when requesting non-existent .aspx pages... I also configured the errorpages in IIS7: Status code: 404 Path: /404.aspx Type: Execute URL Entry type: Local My websites application pool setting is "ASP.NET v4.0" Now why is this still not working?

  • Using design-patterns to transform web-service model classes into local model classes and vise versa

    - by Daniil Petrov
    There is a web-application built with play framework 1.2.7. It contains less than 10 model classes. The main purpose of the application is a lightweight access to a complex remote application (more than 50 model classes). The remote application has its own SOAP API and we use it for synchronization of data. There is a scheduled job in the web-app which makes requests to the remote app. It gets bunches of objects from the remote model and populates corresponding objects of the local model. Currently, there are two groups of classes - the local model and the remote model (generated from wsdl schema). It is not allowed to make any modifications to the remote model. Transformations are being made in the scheduled job class. When it gets objects from the remote app it creates local objects. Recently, it was decided to add a possibility to modify the remote objects. It requires more transformations on our side. We need to transform from remote to local model when reading objects and from local to remote when changing objects. I wonder if this would be possible to use some design-patterns to reduce a number of transformations?

  • SQL SERVER – Concat Strings in SQL Server using T-SQL – SQL in Sixty Seconds #035 – Video

    - by pinaldave
    Concatenating  string is one of the most common tasks in SQL Server and every developer has to come across it. We have to concat the string when we have to see the display full name of the person by first name and last name. In this video we will see various methods to concatenate the strings. SQL Server 2012 has introduced new function CONCAT which concatenates the strings much efficiently. When we concat values with ‘+’ in SQL Server we have to make sure that values are in string format. However, when we attempt to concat integer we have to convert the integers to a string or else it will throw an error. However, with the newly introduce the function of CONCAT in SQL Server 2012 we do not have to worry about this kind of issue. It concatenates strings and integers without casting or converting them. You can specify various values as a parameter to CONCAT functions and it concatenates them together. Let us see how to concat the values in Sixty Seconds: Here is the script which is used in the video. -- Method 1: Concatenating two strings SELECT 'FirstName' + ' ' + 'LastName' AS FullName -- Method 2: Concatenating two Numbers SELECT CAST(1 AS VARCHAR(10)) + ' ' + CAST(2 AS VARCHAR(10)) -- Method 3: Concatenating values of table columns SELECT FirstName + ' ' + LastName AS FullName FROM AdventureWorks2012.Person.Person -- Method 4: SQL Server 2012 CONCAT function SELECT CONCAT('FirstName' , ' ' , 'LastName') AS FullName -- Method 5: SQL Server 2012 CONCAT function SELECT CONCAT('FirstName' , ' ' , 1) AS FullName Related Tips in SQL in Sixty Seconds: SQL SERVER – Concat Function in SQL Server – SQL Concatenation String Function – CONCAT() – A Quick Introduction 2012 Functions – FORMAT() and CONCAT() – An Interesting Usage A Quick Trick about SQL Server 2012 CONCAT Function – PRINT A Quick Trick about SQL Server 2012 CONCAT function What would you like to see in the next SQL in Sixty Seconds video?

  • Using PHP OCI8 with 32-bit PHP on Windows 64-bit

    - by christopher.jones
    The world migration from 32-bit to 64-bit operating systems is gaining pace. However I've seen a couple of customers having difficulty with the PHP OCI8 extension and Oracle DB on Windows 64-bit platforms. The errors vary depending how PHP is run. They may appear in the Apache or PHP log: Unable to load dynamic library 'C:\Program Files (x86)\PHP\ext\php_oci8_11g.dll' - %1 is not a valid Win32 application. or Warning oci_connect(): OCIEnvNlsCreate() failed. There is something wrong with your system - please check that PATH includes the directory with Oracle Instant Client libraries Other than IIS permission issues a common cause seems to be trying to use PHP with libraries from an Oracle 64-bit database on the same machine. There is currently no 64-bit version of PHP on http://php.net/ so there is a library mismatch. A solution is to install Oracle Instant Client 32-bit and make sure that PHP uses these libraries, while not interferring with the 64-bit database on the same machine. Warning: The following hacky steps come untested from a Linux user: Unzip Oracle Instant Client 32-bit and move it to C:\WINDOWS\SYSWOW64\INSTANTCLIENT_11_2. You may need to do this in a console with elevated permissions. Edit your PATH environment variable and insert C:\WINDOWS\SYSTEM32\INSTANTCLIENT_11_2 in the directory list before the entry for the Oracle Home library. Windows makes it so all 32-bit applications that reference C:\WINDOWS\SYSTEM32 actually see the contents of the C:\WINDOWS\SYSWOW64 directory. Your 64-bit database won't find an Instant Client in the real, physical C:\WINDOWS\SYSTEM32 directory and will continue to use the database libraries. Some of our Windows team are concerned about this hack and prefer a more "correct" solution that (i) doesn't require changing the Windows system directory (ii) doesn't add to the "memory" burden about what was configured on the system (iii) works when there are multiple database versions installed. The solution is to write a script which will set the 64-bit (or 32-bit) Oracle libraries in the path as needed before invoking the relevant bit-ness application. This does have a weakness when the application is started as a service. As a footnote: If you don't have a local database and simply need to have 32-bit and 64-bit Instant Client accessible at the same time, try the "symbolic" link approach covered in the hack in this OTN forum thread. Reminder warning: This blog post came untested from a Linux user.

  • Add Intellisense when using the URL rewritingnet config file

    - by Vizioz Limited
    I often use the URL re-writing engine that comes with Umbraco which is from urlrewriting.net and I have always found it very fiddly to edit the configuration file, I wish I have know it was possible to add Intellisense to Visual Studio, and I guessed that most people would also not realise this, after all, who reads the manual right?!So, if you are someone who edits the urlrewriting.config without Intellisense, but would like to use it, this is how you do it :)1) Download the URL rewriting source code files from urlrewriting.net2) Unzip the source files and find the urlwritingnet.xsd file, put this file into your web project, or the directory where your urlredirect.config lives.3) Open up the web project and then open your config file, and hey presto! You should find you now have intellisense!So, the next question is, are there XSD files for the rest of the Umbraco config files, and more importantly for the Umbraco.xml file? If not, does anyone fancy creating them? I am sure intellisense for all these files would be very helpful :)

  • Using DEBUG Mode in Oracle SQL Developer to Log SQL

    - by thatjeffsmith
    Curious how we’re getting the data you see in SQL Developer when you click on something? While many of the dialogs provide a ‘SQL’ panel that shows you the SQL ABOUT to be generated, I’d rather see the SQL AS it’s executed. True, you could set a TRACE or fire up a Monitor Sessions report, but both of those solutions leave me hungry for more. Did you know that SQL Developer has a ‘debug’ mode? It slows the tool down a bit and spits out a lot of information you don’t care about, but it ALSO shows you ALL the SQL that is sent to the database, as you click around the tool! See ALL the SQL that SQL Developer sends to the database on your behalf Enable DEBUG Mode When you see the splash screen as SQL Developer fires up, frantically hit Up, Up, Down, Down, Left, Right, Left, Right, B, A, SELECT, Start. Wait, wrong game. No, all you need to do is go to your SQL Developer directory and navigate down to the ‘bin’ directory. In that directory, find the ‘sqldeveloper.conf’ file. Install Directory - sqldeveloper - bin - sqldeveloper.conf Open it with a text editor. Find this line IncludeConfFile sqldeveloper-nondebug.conf And replace it with this line IncludeConfFile sqldeveloper-debug.conf Save the file. Start up SQL Developer. Observe the Logging Page – Log Panel for the SQL There’s going to be more than just SQL here. You’ll actually see a LOT of other information. If you’re having general problems with the tool and you want to see the nitty-gritty of what’s going on, then this is a good place to satisfy your curiosity and might help us diagnose your issue if you post to the forums or open a ticket with My Oracle Support. You’ll find ‘INFO’ entries that look a little something like this - This is the query used to populate your Tables list in the connection tree. You can double-click on the sql text and get a pop-up window that’s much easier to read. See all that typing we’re saving you? I don’t recommend running in DEBUG mode all the time. Capturing this information and displaying it is more expensive than not doing so. And it provides a lot of information you don’t normally need to see. But when you DO want to know what’s going on and why, this is an excellent way of getting that information. When you’re ready to go back to ‘normal’ mode, just close SQL Developer, go back to your .conf file, and add the ‘nondebug’ bit back.

    I have used closedXML api to read the excel. Here is how you do it. Statistically, this performs better than OpenXML. public DataTable ReadDataFromExcelUsingClosedXML()         { string filePath ="@c:/temp/example.xlsx";             var LobjWorkbook = new XLWorkbook(filePath);             var LobjWorksheet = LobjWorkbook.Worksheets.First();             var LobjFullRange = LobjWorksheet.RangeUsed();             var LobjUsedRange = LobjWorksheet.Range(MobjImportMapper.HeaderRowIndex + 1, 1, LobjFullRange.RangeAddress.LastAddress.RowNumber,                                                     LobjFullRange.RangeAddress.LastAddress.ColumnNumber);             var LiNumberOfcolumnsInTheExcel = LobjUsedRange.ColumnCount();             //  for progress bar             int LiAggregateRowCounter = MobjImportMapper.HeaderRowIndex;             int LiTotalNumberOfRows = LobjWorksheet.RowCount() - LiAggregateRowCounter;             int LiPercentage = 0;             foreach (var LobjRow in LobjUsedRange.RowsUsed())             {                 int LiTemp = 0;                 object[] LobjrowData = new object[LiNumberOfcolumnsInTheExcel + 1];                 LobjrowData[LiTemp] = LobjRow.RangeAddress.FirstAddress.RowNumber;                 LiTemp++;                 LobjRow.Cells().ForEach(PobjCell => LobjrowData[LiTemp++] = PobjCell.Value);                 LdtExcelData.Rows.Add(LobjrowData);                 //  for progress bar                 LiPercentage = ((100 * LiAggregateRowCounter / LiTotalNumberOfRows) / 4) * 3;                 if (LiPercentage > 5)                     PobjBackgoundWorker.ReportProgress(LiPercentage);                 LiAggregateRowCounter++;                 // =====================             }             return LdtExcelData;         } span.fullpost {display:none;}

  • Setting up a Reverse Proxy using IIS, URL Rewrite and ARR

    - by The Official Microsoft IIS Site
    Today there was a question in the IIS.net Forums asking how to expose two different Internet sites from another site making them look like if they were subdirectories in the main site. So for example the goal was to have a site: www.site.com expose a www.site.com/company1 and a www.site.com/company2 and have the content from “www.company1.com” served for the first one and “www.company2.com” served in the second one. Furthermore we would like to have the responses cached in the server for performance...(read more)

    I can't get ANYTHING working on linux. I'm trying to compile CudaMiner. sudo make: ypt-jane.o `test -f 'scrypt-jane.cpp' || echo './'`scrypt-jane.cpp mv -f .deps/cudaminer-scrypt-jane.Tpo .deps/cudaminer-scrypt-jane.Po nvcc -g -O2 -Xptxas "-abi=no -v" -arch=compute_10 --maxrregcount=64 --ptxas-options=-v -I./compat/jansson -o salsa_kernel.o -c salsa_kernel.cu /bin/bash: nvcc: command not found make[2]: *** [salsa_kernel.o] Error 127 make[2]: Leaving directory `/var/progs/CudaMiner' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/progs/CudaMiner' make: *** [all] Error 2 So, kind of interesting: nvcc: nvcc fatal : No input files specified; use option --help for more information Whereas sudo nvcc: sudo: nvcc: command not found Huh?? I have identical exports listed in ~/.bashrc AND /etc/bash.bashrc. (Nvcc is located in: /usr/local/cuda-5.0/bin/nvcc) I also tried changing the current path, to no avail: $ sudo bash -c 'echo $PATH' /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin $ PATH=$PATH:/usr/local/cuda-5.0/bin/nvcc $ sudo bash -c 'echo $PATH' /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin Thanks in advance!

  • Using dnnModal.show in your modules and content

    - by Chris Hammond
    One thing that was added in DotNetNuke 6 but hasn’t been covered in great detail is a method called dnnModal.show. Calling this method is fairly straight forward depending on your need, but before we get into how to call/use the method, let’s talk about what it does first. dnnModal.show is a method that gets called via JavaScript and allows you to load up a URL into a modal popup window within your DotNetNuke site. Basically it will take that URL and load it into an IFrame within the current DotNetNuke...(read more)

  • Localization in ASP.NET MVC 2 using ModelMetadata

    - by rajbk
    This post uses an MVC 2 RTM application inside VS 2010 that is targeting the .NET Framework 4. .NET 4 DataAnnotations comes with a new Display attribute that has several properties including specifying the value that is used for display in the UI and a ResourceType. Unfortunately, this attribute is new and is not supported in MVC 2 RTM. The good news is it will be supported and is currently available in the MVC Futures release. The steps to get this working are shown below: Download the MVC futures library   Add a reference to the Microsoft.Web.MVC.AspNet4 dll.   Add a folder in your MVC project where you will store the resx files   Open the resx file and change “Access Modifier” to “Public”. This allows the resources to accessible from other assemblies. Internaly, it changes the “Custom Tool” used to generate the code behind from  ResXFileCodeGenerator to “PublicResXFileCodeGenerator”    Add your localized strings in the resx.   Register the new ModelMetadataProvider protected void Application_Start() { AreaRegistration.RegisterAllAreas();   RegisterRoutes(RouteTable.Routes);   //Add this ModelMetadataProviders.Current = new DataAnnotations4ModelMetadataProvider(); DataAnnotations4ModelValidatorProvider.RegisterProvider(); }   Use the Display attribute in your Model public class Employee { [Display(Name="ID")] public int ID { get; set; }   [Display(ResourceType = typeof(Common), Name="Name")] public string Name { get; set; } } Use the new HTML UI Helpers in your strongly typed view: <%: Html.EditorForModel() %> <%: Html.EditorFor(m => m) %> <%: Html.LabelFor(m => m.Name) %> ..and you are good to go. Adventure is out there!

  • Using BPEL Performance Statistics to Diagnose Performance Bottlenecks

    - by fip
    Tuning performance of Oracle SOA 11G applications could be challenging. Because SOA is a platform for you to build composite applications that connect many applications and "services", when the overall performance is slow, the bottlenecks could be anywhere in the system: the applications/services that SOA connects to, the infrastructure database, or the SOA server itself.How to quickly identify the bottleneck becomes crucial in tuning the overall performance. Fortunately, the BPEL engine in Oracle SOA 11G (and 10G, for that matter) collects BPEL Engine Performance Statistics, which show the latencies of low level BPEL engine activities. The BPEL engine performance statistics can make it a bit easier for you to identify the performance bottleneck. Although the BPEL engine performance statistics are always available, the access to and interpretation of them are somewhat obscure in the early and current (PS5) 11G versions. This blog attempts to offer instructions that help you to enable, retrieve and interpret the performance statistics, before the future versions provides a more pleasant user experience. Overview of BPEL Engine Performance Statistics  SOA BPEL has a feature of collecting some performance statistics and store them in memory. One MBean attribute, StatLastN, configures the size of the memory buffer to store the statistics. This memory buffer is a "moving window", in a way that old statistics will be flushed out by the new if the amount of data exceeds the buffer size. Since the buffer size is limited by StatLastN, impacts of statistics collection on performance is minimal. By default StatLastN=-1, which means no collection of performance data. Once the statistics are collected in the memory buffer, they can be retrieved via another MBean oracle.as.soainfra.bpel:Location=[Server Name],name=BPELEngine,type=BPELEngine.> My friend in Oracle SOA development wrote this simple 'bpelstat' web app that looks up and retrieves the performance data from the MBean and displays it in a human readable form. It does not have beautiful UI but it is fairly useful. Although in Oracle SOA 11.1.1.5 onwards the same statistics can be viewed via a more elegant UI under "request break down" at EM -> SOA Infrastructure -> Service Engines -> BPEL -> Statistics, some unsophisticated minds like mine may still prefer the simplicity of the 'bpelstat' JSP. One thing that simple JSP does do well is that you can save the page and send it to someone to further analyze Follows are the instructions of how to install and invoke the BPEL statistic JSP. My friend in SOA Development will soon blog about interpreting the statistics. Stay tuned. Step1: Enable BPEL Engine Statistics for Each SOA Servers via Enterprise Manager First st you need to set the StatLastN to some number as a way to enable the collection of BPEL Engine Performance Statistics EM Console -> soa-infra(Server Name) -> SOA Infrastructure -> SOA Administration -> BPEL Properties Click on "More BPEL Configuration Properties" Click on attribute "StatLastN", set its value to some integer number. Typically you want to set it 1000 or more. Step 2: Download and Deploy bpelstat.war File to Admin Server, Note: the WAR file contains a JSP that does NOT have any security restriction. You do NOT want to keep in your production server for a long time as it is a security hazard. Deactivate the war once you are done. Download the bpelstat.war to your local PC At WebLogic Console, Go to Deployments -> Install Click on the "upload your file(s)" Click the "Browse" button to upload the deployment to Admin Server Accept the uploaded file as the path, click next Check the default option "Install this deployment as an application" Check "AdminServer" as the target server Finish the rest of the deployment with default settings Console -> Deployments Check the box next to "bpelstat" application Click on the "Start" button. It will change the state of the app from "prepared" to "active" Step 3: Invoke the BPEL Statistic Tool The BPELStat tool merely call the MBean of BPEL server and collects and display the in-memory performance statics. You usually want to do that after some peak loads. Go to http://<admin-server-host>:<admin-server-port>/bpelstat Enter the correct admin hostname, port, username and password Enter the SOA Server Name from which you want to collect the performance statistics. For example, SOA_MS1, etc. Click Submit Keep doing the same for all SOA servers. Step 3: Interpret the BPEL Engine Statistics You will see a few categories of BPEL Statistics from the JSP Page. First it starts with the overall latency of BPEL processes, grouped by synchronous and asynchronous processes. Then it provides the further break down of the measurements through the life time of a BPEL request, which is called the "request break down". 1. Overall latency of BPEL processes The top of the page shows that the elapse time of executing the synchronous process TestSyncBPELProcess from the composite TestComposite averages at about 1543.21ms, while the elapse time of executing the asynchronous process TestAsyncBPELProcess from the composite TestComposite2 averages at about 1765.43ms. The maximum and minimum latency were also shown. Synchronous process statistics <statistics>     <stats key="default/TestComposite!2.0.2-ScopedJMSOSB*soa_bfba2527-a9ba-41a7-95c5-87e49c32f4ff/TestSyncBPELProcess" min="1234" max="4567" average="1543.21" count="1000">     </stats> </statistics> Asynchronous process statistics <statistics>     <stats key="default/TestComposite2!2.0.2-ScopedJMSOSB*soa_bfba2527-a9ba-41a7-95c5-87e49c32f4ff/TestAsyncBPELProcess" min="2234" max="3234" average="1765.43" count="1000">     </stats> </statistics> 2. Request break down Under the overall latency categorized by synchronous and asynchronous processes is the "Request breakdown". Organized by statistic keys, the Request breakdown gives finer grain performance statistics through the life time of the BPEL requests.It uses indention to show the hierarchy of the statistics. Request breakdown <statistics>     <stats key="eng-composite-request" min="0" max="0" average="0.0" count="0">         <stats key="eng-single-request" min="22" max="606" average="258.43" count="277">             <stats key="populate-context" min="0" max="0" average="0.0" count="248"> Please note that in SOA 11.1.1.6, the statistics under Request breakdown is aggregated together cross all the BPEL processes based on statistic keys. It does not differentiate between BPEL processes. If two BPEL processes happen to have the statistic that share same statistic key, the statistics from two BPEL processes will be aggregated together. Keep this in mind when we go through more details below. 2.1 BPEL process activity latencies A very useful measurement in the Request Breakdown is the performance statistics of the BPEL activities you put in your BPEL processes: Assign, Invoke, Receive, etc. The names of the measurement in the JSP page directly come from the names to assign to each BPEL activity. These measurements are under the statistic key "actual-perform" Example 1:  Follows is the measurement for BPEL activity "AssignInvokeCreditProvider_Input", which looks like the Assign activity in a BPEL process that assign an input variable before passing it to the invocation:                                <stats key="AssignInvokeCreditProvider_Input" min="1" max="8" average="1.9" count="153">                                     <stats key="sensor-send-activity-data" min="0" max="1" average="0.0" count="306">                                     </stats>                                     <stats key="sensor-send-variable-data" min="0" max="0" average="0.0" count="153">                                     </stats>                                     <stats key="monitor-send-activity-data" min="0" max="0" average="0.0" count="306">                                     </stats>                                 </stats> Note: because as previously mentioned that the statistics cross all BPEL processes are aggregated together based on statistic keys, if two BPEL processes happen to name their Invoke activity the same name, they will show up at one measurement (i.e. statistic key). Example 2: Follows is the measurement of BPEL activity called "InvokeCreditProvider". You can not only see that by average it takes 3.31ms to finish this call (pretty fast) but also you can see from the further break down that most of this 3.31 ms was spent on the "invoke-service".                                  <stats key="InvokeCreditProvider" min="1" max="13" average="3.31" count="153">                                     <stats key="initiate-correlation-set-again" min="0" max="0" average="0.0" count="153">                                     </stats>                                     <stats key="invoke-service" min="1" max="13" average="3.08" count="153">                                         <stats key="prep-call" min="0" max="1" average="0.04" count="153">                                         </stats>                                     </stats>                                     <stats key="initiate-correlation-set" min="0" max="0" average="0.0" count="153">                                     </stats>                                     <stats key="sensor-send-activity-data" min="0" max="0" average="0.0" count="306">                                     </stats>                                     <stats key="sensor-send-variable-data" min="0" max="0" average="0.0" count="153">                                     </stats>                                     <stats key="monitor-send-activity-data" min="0" max="0" average="0.0" count="306">                                     </stats>                                     <stats key="update-audit-trail" min="0" max="2" average="0.03" count="153">                                     </stats>                                 </stats> 2.2 BPEL engine activity latency Another type of measurements under Request breakdown are the latencies of underlying system level engine activities. These activities are not directly tied to a particular BPEL process or process activity, but they are critical factors in the overall engine performance. These activities include the latency of saving asynchronous requests to database, and latency of process dehydration. My friend Malkit Bhasin is working on providing more information on interpreting the statistics on engine activities on his blog (https://blogs.oracle.com/malkit/). I will update this blog once the information becomes available. Update on 2012-10-02: My friend Malkit Bhasin has published the detail interpretation of the BPEL service engine statistics at his blog http://malkit.blogspot.com/2012/09/oracle-bpel-engine-soa-suite.html.
