  • Get script for every action in SQL Server Management Studio

    I am always conscious to keep a record of all operations performed on my database servers. Operations through T-SQL in an SSMS query pane can easily be saved in query files. For table modifications through SSMS designer I have predefined setting to generate T-SQL scripts. However there are numerous database and server level tasks that I use the SSMS GUI and I would like to have a script of these changes for later reference. Examples of such actions through the SSMS GUI are backup/restore, changing compatibility level of a database, manipulating permissions, dealing with database or log files or creating/manipulating any login/user. I am looking for any way to generate T-SQL code for such actions, so that it may be kept for later reference

  • Managing service references and endpoint configurations for Silverlight applications

    Youve written your service. Youve written your Silverlight application. You Add Service Reference to your application and got the client proxy code. Your app works on your machine and you push it out. FAIL. NotFound. Crap. You forgot that your service reference had your local URI endpoint in there and when you moved it to staging and/or production it failed. You start cursing Microsoft and the Silverlight team and add to the threads in the forums or perhaps initiate a new wishlist item for the...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Quality Assurance=inspections, reviews..?

    - by user970696
    Studying this subject extensively, the most books state the following: Quality Assurance: prevention activity. Act of inspection, reviewing.. Quality Control: testing While there are some exceptions that mention that QA deals with just processes (planning, strategy, standard application etc.) which is IMHO much closer to real QA, yet I cannot find any good reference in Google Books. I believe that inspections, reviews, testing is all quality control as it is about checking products, no matter if it is the final one or work products. The problem is that so many authors do not agree. I would be grateful for detailed explanation, ideally with a reference.

  • best practice for last-modified and created dates

    - by drewbenn
    I have a website with a handful (currently 3; I anticipate about a dozen when it's complete) of static html pages. I'd like to include "created" and "last-modified" dates in the pages for the benefit of visitors who arrive a week or a month or a few years from now. I expect anyone who cares to be viewing the source, so I could do: <!-- created yyyy-mm-dd, last-modified yyyy-mm-dd --> but I'd like to use something more standard (and elegant). I've found one reference to last modified (but only a mention in the text, not an actual code reference, so I'm not positive how to properly implement it) but not created. Is there a proper way to display both (or at least one) of these dates?

  • Consuming OData based Rest service in C# [en-US]

    - by ruimachado
    Nowadays comunication between applications is an active topic with daily usage and a large amount of pratical appliances. While developing an app in witch I had to consume an OData I found out that combining Linq with my code made this operation pretty easy.The algorithm to consume OData starts with adding a service reference to Visual Studio:After adding the service reference in wich you define the uri to the service, we start building our code.In your code the algorithm is the following:Define the Uri to your OData ServiceDefine the context of your odata, wich contains all entities exposed by the service.Query the context using LinqPrint the resultEasy and simple.Example code:01public static void Main(string[] args){02 03        Uri serviceUri= newUri("http://example.host.odataservice.net/service.svc", UriKind.Absolute);04        ODataService.ServiceEntities context = newODataService.ServiceEntities (serviceUri);05 06        context.Credentials = newSystem.Net.NetworkCredential(Username,Password);07 08         var query = from ServiceObject in context.YourEntity09                     select ServiceObject ;10 11        foreach (var myObject in query)12        {13            Console.WriteLine("\n Field1: {0} | Field2: {1}",14            myObject .Field1, myObject .Field2);15 16        }17}That’s it.Thank you,Rui Machadorpmachado.wordpress.com

  • 'normal' SVC versus 'Silverlight' SVC (WCF)

    - by Michel
    Hi, i'm trying to call a WCF service from my Silverlight 3 app. But... when trying to create a 'silverlight enabled wcf service' in my web project, my VS2008 crashes during creating the item (i think while editing the web.config). So i thought: let's create a 'normal' wcf service, and manually edit it to be a 'silverlight enabled webservice'. So i wondered what the differences are, and second: why is there a difference between a service called from a silverlight app and a non-silverlight app? This is what i have now for the binding (i have a service without an Interface contract, just a direct class exposed, to begin with): <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="RadControlsSilverlightApp1.Web.GetNewDataBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="customBinding0"> <binaryMessageEncoding /> <httpTransport /> </binding> </customBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <services> <service behaviorConfiguration="RadControlsSilverlightApp1.Web.GetNewDataBehavior" name="RadControlsSilverlightApp1.Web.GetNewData"> <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0" contract="RadControlsSilverlightApp1.Web.GetNewData" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> This one doesn't work because when i add a reference to it from the silverlight app i get these messages: Warning 2 Custom tool warning: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: Exception has been thrown by the target of an invocation.

  • Java thread dump where main thread has no call stack? (jsvc)

    - by dwhsix
    We have a java process running as a daemon (under jsvc). Every several days it just stops doing any work; output to the logfile stops (it is pretty verbose, on 5-minute intervals) and it consumes no CPU or IO. There are no exceptions logged in the logfile nor in syserr or sysout. The last log statement is just prior to a db commit being done, but there is no open connection on the db server (MySQL) and reviewing the code, there should always be additional log output after that, even if it had encountered an exception that was going to bubble up. The most curious thing I find is that in the thread dump (included below), there's no thread in our code at all, and the main thread seems to have no context whatsoever: "main" prio=10 tid=0x0000000000614000 nid=0x445d runnable [0x0000000000000000] java.lang.Thread.State: RUNNABLE As noted earlier, this is a daemon process running using jsvc, but I don't know if that has anything to do with it (I can restructure the code to also allow running it directly, to test).

  • Why does Keychain Services return the wrong keychain content?

    - by Graham Lee
    I've been trying to use persistent keychain references in an iPhone application. I found that if I created two different keychain items, I would get a different persistent reference each time (they look like 'genp.......1', 'genp.......2', …). However, attempts to look up the items by persistent reference always returned the content of the first item. Why should this be? I confirmed that my keychain-saving code was definitely creating new items in each case (rather than updating existing items), and was not getting any errors. And as I say, Keychain Services is giving a different persistent reference for each item. I've managed to solve my immediate problem by searching for keychain items by attribute rather than persistent references, but it would be easier to use persistent references so I'd appreciate solving this problem. Here's my code: - (NSString *)keychainItemWithName: (NSString *)name { NSString *path = [GLApplicationSupportFolder() stringByAppendingPathComponent: name]; NSData *persistentRef = [NSData dataWithContentsOfFile: path]; if (!persistentRef) { NSLog(@"no persistent reference for name: %@", name); return nil; } NSArray *refs = [NSArray arrayWithObject: persistentRef]; //get the data CFMutableDictionaryRef params = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionaryAddValue(params, kSecMatchItemList, refs); CFDictionaryAddValue(params, kSecClass, kSecClassGenericPassword); CFDictionaryAddValue(params, kSecReturnData, kCFBooleanTrue); CFDataRef item = NULL; OSStatus result = SecItemCopyMatching(params, (CFTypeRef *)&item); CFRelease(params); if (result != errSecSuccess) { NSLog(@"error %d retrieving keychain reference for name: %@", result, name); return nil; } NSString *token = [[NSString alloc] initWithData: (NSData *)item encoding: NSUTF8StringEncoding]; CFRelease(item); return [token autorelease]; } - (void)setKeychainItem: (NSString *)newToken forName: (NSString *)name { NSData *tokenData = [newToken dataUsingEncoding: NSUTF8StringEncoding]; //firstly, find out whether the item already exists NSDictionary *searchAttributes = [NSDictionary dictionaryWithObjectsAndKeys: name, kSecAttrAccount, kCFBooleanTrue, kSecReturnAttributes, nil]; NSDictionary *foundAttrs = nil; OSStatus searchResult = SecItemCopyMatching((CFDictionaryRef)searchAttributes, (CFTypeRef *)&foundAttrs); if (noErr == searchResult) { NSMutableDictionary *toStore = [foundAttrs mutableCopy]; [toStore setObject: tokenData forKey: (id)kSecValueData]; OSStatus result = SecItemUpdate((CFDictionaryRef)foundAttrs, (CFDictionaryRef)toStore); if (result != errSecSuccess) { NSLog(@"error %d updating keychain", result); } [toStore release]; return; } //need to create the item. CFMutableDictionaryRef params = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionaryAddValue(params, kSecClass, kSecClassGenericPassword); CFDictionaryAddValue(params, kSecAttrAccount, name); CFDictionaryAddValue(params, kSecReturnPersistentRef, kCFBooleanTrue); CFDictionaryAddValue(params, kSecValueData, tokenData); NSData *persistentRef = nil; OSStatus result = SecItemAdd(params, (CFTypeRef *)&persistentRef); CFRelease(params); if (result != errSecSuccess) { NSLog(@"error %d from keychain services", result); return; } NSString *path = [GLApplicationSupportFolder() stringByAppendingPathComponent: name]; [persistentRef writeToFile: path atomically: NO]; [persistentRef release]; }

  • Reordering Variadic Parameters

    - by void-pointer
    I have come across the need to reorder a variadic list of parameters that is supplied to the constructor of a struct. After being reordered based on their types, the parameters will be stored as a tuple. My question is how this can be done so that a modern C++ compiler (e.g. g++-4.7) will not generate unnecessary load or store instructions. That is, when the constructor is invoked with a list of parameters of variable size, it efficiently pushes each parameter into place based on an ordering over the parameters' types. Here is a concrete example. Assume that the base type of every parameter (without references, rvalue references, pointers, or qualifiers) is either char, int, or float. How can I make it so that all the parameters of base type char appear first, followed by all of those of base type int (which leaves the parameters of base type float last). The relative order in which the parameters were given should not be violated within sublists of homogeneous base type. Example: foo::foo() is called with arguments float a, char&& b, const float& c, int&& d, char e. The tuple tupe is std::tuple<char, char, int, float, float>, and it is constructed like so: tuple_type{std::move(b), e, std::move(d), a, c}. Consider the struct defined below, and assume that the metafunction deduce_reordered_tuple_type is already implemented. How would you write the constructor so that it works as intended? If you think that the code for deduce_reodered_tuple_type, would be useful to you, I can provide it; it's a little long. template <class... Args> struct foo { // Assume that the metafunction deduce_reordered_tuple_type is defined. typedef typename deduce_reordered_tuple_type<Args...>::type tuple_type; tuple_type t_; foo(Args&&... args) : t_{reorder_and_forward_parameters<Args>(args)...} {} }; Edit 1 The technique I describe above does have applications in mathematical frameworks that make heavy use of expression templates, variadic templates, and metaprogramming in order to perform aggressive inlining. Suppose that you wish to define an operator that takes the product of several expressions, each of which may be passed by reference, reference to const, or rvalue reference. (In my case, the expressions are conditional probability tables and the operation is the factor product, but something like matrix multiplication works suitably as well.) You need access to the data provided by each expression in order to evaluate the product. Consequently, you must move the expressions passed as rvalue references, copy the expressions passed by reference to const, and take the addresses of expressions passed by reference. Using the technique I describe above now poses several benefits. Other expressions can use uniform syntax to access data elements from this expression, since all of the heavy-lifting metaprogramming work is done beforehand, within the class. We can save stack space by grouping the pointers together and storing the larger expressions towards the end of the tuple. Implementing certain types of queries becomes much easier (e.g. check whether any of the pointers stored in the tuple aliases a given pointer). Thank you very much for your help!

  • How to safely operate on parameters in threads, using C++ & Pthreads?

    - by ChrisCphDK
    Hi. I'm having some trouble with a program using pthreads, where occassional crashes occur, that could be related to how the threads operate on data So I have some basic questions about how to program using threads, and memory layout: Assume that a public class function performs some operations on some strings, and returns the result as a string. The prototype of the function could be like this: std::string SomeClass::somefunc(const std::string &strOne, const std::string &strTwo) { //Error checking of strings have been omitted std::string result = strOne.substr(0,5) + strTwo.substr(0,5); return result; } Is it correct to assume that strings, being dynamic, are stored on the heap, but that a reference to the string is allocated on the stack at runtime? Stack: [Some mem addr] pointer address to where the string is on the heap Heap: [Some mem addr] memory allocated for the initial string which may grow or shrink To make the function thread safe, the function is extended with the following mutex (which is declared as private in the "SomeClass") locking: std::string SomeClass::somefunc(const std::string &strOne, const std::string &strTwo) { pthread_mutex_lock(&someclasslock); //Error checking of strings have been omitted std::string result = strOne.substr(0,5) + strTwo.substr(0,5); pthread_mutex_unlock(&someclasslock); return result; } Is this a safe way of locking down the operations being done on the strings (all three), or could a thread be stopped by the scheduler in the following cases, which I'd assume would mess up the intended logic: a. Right after the function is called, and the parameters: strOne & strTwo have been set in the two reference pointers that the function has on the stack, the scheduler takes away processing time for the thread and lets a new thread in, which overwrites the reference pointers to the function, which then again gets stopped by the scheduler, letting the first thread back in? b. Can the same occur with the "result" string: the first string builds the result, unlocks the mutex, but before returning the scheduler lets in another thread which performs all of it's work, overwriting the result etc. Or are the reference parameters / result string being pushed onto the stack while another thread is doing performing it's task? Is the safe / correct way of doing this in threads, and "returning" a result, to pass a reference to a string that will be filled with the result instead: void SomeClass::somefunc(const std::string &strOne, const std::string &strTwo, std::string result) { pthread_mutex_lock(&someclasslock); //Error checking of strings have been omitted result = strOne.substr(0,5) + strTwo.substr(0,5); pthread_mutex_unlock(&someclasslock); } The intended logic is that several objects of the "SomeClass" class creates new threads and passes objects of themselves as parameters, and then calls the function: "someFunc": int SomeClass::startNewThread() { pthread_attr_t attr; pthread_t pThreadID; if(pthread_attr_init(&attr) != 0) return -1; if(pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED) != 0) return -2; if(pthread_create(&pThreadID, &attr, proxyThreadFunc, this) != 0) return -3; if(pthread_attr_destroy(&attr) != 0) return -4; return 0; } void* proxyThreadFunc(void* someClassObjPtr) { return static_cast<SomeClass*> (someClassObjPtr)->somefunc("long string","long string"); } Sorry for the long description. But I hope the questions and intended purpose is clear, if not let me know and I'll elaborate. Best regards. Chris

  • BizTalk configuration broken following WCF hotfix installation

    - by Sir Crispalot
    I usually post over on StackOverflow, but thought this was probably better suited to ServerFault. Please migrate if I'm wrong! I am developing a WCF service and a BizTalk application on my workstation at the moment. As part of the WCF service, I had to install hotfix 971493 from Microsoft which updates some core WCF assemblies. Following installation of that hotfix, I am now experiencing severe issues in my existing BizTalk application. When I attempt to configure the properties of an existing WCF-Custom receive location, I get this error: Error loading properties (System.IO.FileLoadException) The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) If I click OK (the same error repeats four times) I eventually see the WCF-Custom properties dialog. However if I click on the various tabs, I continue to receive errors: The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) (Microsoft.BizTalk.Adapter.Wcf.Admin) The WCF-Custom receive location was working yesterday, and I installed the hotfix this morning. I'm guessing these two are related, and that BizTalk somehow has a reference to the old WCF assemblies. Does anyone know how I can fix this?

  • How flexible is the 'indirect' function?

    - by Chuck
    My curiosity pushes me to ask this question. If I were to have a series of functions that referenced a different column in a worksheet but all ended on the same row of data is there a way to point the 'row' part of a cell reference to a blank cell and use it has a variable to show the results of the functions up to a desired row simultaneously? Example: =Average('worksheet 1'.$A$1:'worksheet 1'.$A100) =Max('worksheet 1'.$B$1:'worksheet 1'.$B100) =Min('worksheet 1'.$C$1:'worksheet 1'.$C100) =Sum('worksheet 1'.$D$1:'worksheet 1'.$D100) Pseudo formulas... =Average('worksheet 1'.$A$1:'worksheet 1'.$A*('worksheet 2'.$A$1)*) =Max('worksheet 1'.$B$1:'worksheet 1'.$B*('worksheet 2'.$A$1)*) =Min('worksheet 1'.$C$1:'worksheet 1'.$C*('worksheet 2'.$A$1)*) =Sum('worksheet 1'.$D$1:'worksheet 1'.$D*('worksheet 2'.$A$1)*) Where 'worksheet 2'.$A$1 would only contain a number corresponding to a row in 'worksheet 1'. After stumbling upon and playing with the indirect() function I have only been able to replace the entire cell reference (Column and Row) with any success. The formula so far =SUM('worksheet 1'.C3:INDIRECT(A1)) Where A1 is on 'worksheet 2' and contains a full cell reference pointing to 'worksheet 1'. Any pointers?

  • virtual memory commited

    After a server bounce happens, and after around 40-45 days time period, we receive continuous “Committed Virtual Memory” alerts which indicates the usage of swap space in the magnitude of 4GB This also causes the application to perform very slowly and experience a number of stalled transactions. Server Setup: 4 Tomcat Servers (version 7.0.22) that are load balanced (not clustered) by 2 Apache Servers.

If the ThreadLocal is not strongly referenced, it will be garbage-collected, even though various threads have values stored via that ThreadLocal. Additionally, ThreadLocal values are actually stored in the Thread; if a thread dies, all of the values associated with that thread through a ThreadLocal are collected. If you have a ThreadLocal as a final class member, that's a strong reference, and it cannot be collected until the class is unloaded. But this is how any class member works, and isn't considered a memory leak. The cited problem only comes into play when the value stored in a ThreadLocal strongly references that ThreadLocal—sort of a circular reference. In this case, the value (a SimpleDateFormat), has no backwards reference to the ThreadLocal. There's no memory leak in this code. Can anyone please let me know what could be the cause of this and what to be monitored?

  • Multiple SSL certificates on one server

    - by Kyle O'Brien
    We're hosting two websites on our fairly tiny but dedicated production server. Both website require SSL authentication. So, we have virtualhosts set up for both of them. They both reference their own domain.key, domain.crt and domain.intermediate.crt files. Each CSR and certificate file for each site was setup using its own unique information and nothing is shared between them (other than the server itself) However, which ever site's symbolic link (set up in /etc/apache2/sites-enabled) is reference first, is the site who's certificate is referenced even if we're visiting the second site. So for example, assume our companies are Cadbury and Nestle. We set up both sites with their own certificates but we create Cadbury's symbolic link in apache's site-enabled folder first and then Nestle's. You can visit Nestle perfectly fine but if you check the certificate installation, it reference's Cadbury's certificate. We're hosting these websites on a dedicated Ubuntu 12.04.3 LTS server. Both certificates are provided by Thawte.com. I came across a few potential solutions with no degree of success. I'm hoping someone else has a decent solution? Thanks Edit: The only other solution that seems to have provided success to some people is using SNI with Apache. However, the setups here didn't seem to coincide with our setup at all.

  • JQuery > XSLT Plugin > Component returned failure code: 0x80600011 [nsIXSLTProcessorObsolete.transfo

    - by Sean Ochoa
    So, I'm using the XSLT plugin for JQuery, and here's my code: function AddPlotcardEventHandlers(){ // some code } function reportError(exception){ alert(exception.constructor.name + " Exception: " + ((exception.name) ? exception.name : "[unknown name]") + " - " + exception.message); } function GetPlotcards(){ $("#content").xslt("../xml/plotcards.xml","../xslt/plotcards.xsl", AddPlotcardEventHandlers,reportError); } Here's the modified jquery plugin. I say that its modified because I've added callbacks for success and error handling. /* * jquery.xslt.js * * Copyright (c) 2005-2008 Johann Burkard (<mailto:[email protected]>) * <http://eaio.com> * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

  • Please help me understand why my XSL Transform is not transforming

    - by Damovisa
    I'm trying to transform one XML format to another using XSL. Try as I might, I can't seem to get a result. I've hacked away at this for a while now and I've had no success. I'm not even getting any exceptions. I'm going to post the entire code and hopefully someone can help me work out what I've done wrong. I'm aware there are likely to be problems in the xsl I have in terms of selects and matches, but I'm not fussed about that at the moment. The output I'm getting is the input XML without any XML tags. The transformation is simply not occurring. Here's my XML Document: <?xml version="1.0"?> <Transactions> <Account> <PersonalAccount> <AccountNumber>066645621</AccountNumber> <AccountName>A Smith</AccountName> <CurrentBalance>-200125.96</CurrentBalance> <AvailableBalance>0</AvailableBalance> <AccountType>LOAN</AccountType> </PersonalAccount> </Account> <StartDate>2010-03-01T00:00:00</StartDate> <EndDate>2010-03-23T00:00:00</EndDate> <Items> <Transaction> <ErrorNumber>-1</ErrorNumber> <Amount>12000</Amount> <Reference>Transaction 1</Reference> <CreatedDate>0001-01-01T00:00:00</CreatedDate> <EffectiveDate>2010-03-15T00:00:00</EffectiveDate> <IsCredit>true</IsCredit> <Balance>-324000</Balance> </Transaction> <Transaction> <ErrorNumber>-1</ErrorNumber> <Amount>11000</Amount> <Reference>Transaction 2</Reference> <CreatedDate>0001-01-01T00:00:00</CreatedDate> <EffectiveDate>2010-03-14T00:00:00</EffectiveDate> <IsCredit>true</IsCredit> <Balance>-324000</Balance> </Transaction> </Items> </Transactions> Here's my XSLT: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="xml" /> <xsl:param name="currentdate"></xsl:param> <xsl:template match="Transactions"> <xsl:element name="OFX"> <xsl:element name="SIGNONMSGSRSV1"> <xsl:element name="SONRS"> <xsl:element name="STATUS"> <xsl:element name="CODE">0</xsl:element> <xsl:element name="SEVERITY">INFO</xsl:element> </xsl:element> <xsl:element name="DTSERVER"><xsl:value-of select="$currentdate" /></xsl:element> <xsl:element name="LANGUAGE">ENG</xsl:element> </xsl:element> </xsl:element> <xsl:element name="BANKMSGSRSV1"> <xsl:element name="STMTTRNRS"> <xsl:element name="TRNUID">1</xsl:element> <xsl:element name="STATUS"> <xsl:element name="CODE">0</xsl:element> <xsl:element name="SEVERITY">INFO</xsl:element> </xsl:element> <xsl:element name="STMTRS"> <xsl:element name="CURDEF">AUD</xsl:element> <xsl:element name="BANKACCTFROM"> <xsl:element name="BANKID">RAMS</xsl:element> <xsl:element name="ACCTID"><xsl:value-of select="Account/PersonalAccount/AccountNumber" /></xsl:element> <xsl:element name="ACCTTYPE"><xsl:value-of select="Account/PersonalAccount/AccountType" /></xsl:element> </xsl:element> <xsl:element name="BANKTRANLIST"> <xsl:element name="DTSTART"><xsl:value-of select="StartDate" /></xsl:element> <xsl:element name="DTEND"><xsl:value-of select="EndDate" /></xsl:element> <xsl:for-each select="Items/Transaction"> <xsl:element name="STMTTRN"> <xsl:element name="TRNTYPE"><xsl:choose><xsl:when test="IsCredit">CREDIT</xsl:when><xsl:otherwise>DEBIT</xsl:otherwise></xsl:choose></xsl:element> <xsl:element name="DTPOSTED"><xsl:value-of select="EffectiveDate" /></xsl:element> <xsl:element name="DTUSER"><xsl:value-of select="CreatedDate" /></xsl:element> <xsl:element name="TRNAMT"><xsl:value-of select="Amount" /></xsl:element> <xsl:element name="FITID" /> <xsl:element name="NAME"><xsl:value-of select="Reference" /></xsl:element> <xsl:element name="MEMO"><xsl:value-of select="Reference" /></xsl:element> </xsl:element> </xsl:for-each> </xsl:element> <xsl:element name="LEDGERBAL"> <xsl:element name="BALAMT"><xsl:value-of select="Account/PersonalAccount/CurrentBalance" /></xsl:element> <xsl:element name="DTASOF"><xsl:value-of select="EndDate" /></xsl:element> </xsl:element> </xsl:element> </xsl:element> </xsl:element> </xsl:element> </xsl:template> </xsl:stylesheet> Here's my method to transform my XML: public string TransformToXml(XmlElement xmlElement, Dictionary<string, object> parameters) { string strReturn = ""; // Load the XSLT Document XslCompiledTransform xslt = new XslCompiledTransform(); xslt.Load(xsltFileName); // arguments XsltArgumentList args = new XsltArgumentList(); if (parameters != null && parameters.Count > 0) { foreach (string key in parameters.Keys) { args.AddParam(key, "", parameters[key]); } } //Create a memory stream to write to Stream objStream = new MemoryStream(); // Apply the transform xslt.Transform(xmlElement, args, objStream); objStream.Seek(0, SeekOrigin.Begin); // Read the contents of the stream StreamReader objSR = new StreamReader(objStream); strReturn = objSR.ReadToEnd(); return strReturn; } The contents of strReturn is an XML tag (<?xml version="1.0" encoding="utf-8"?>) followed by a raw dump of the contents of the original XML document, stripped of XML tags.

  • Add Silverlight Bing Maps Control to Windows Mobile 7 application

    - by Jacob
    I know the bits just came out today, but one of the first things I want to do with the newly released Windows Mobile 7 SDK is put a map up on the screen and mess around. I've downloaded the latest version of the Silverlight Maps Control and added the references to my application. As a matter of fact, the VS 2010 design view of the MainPage.xaml shows the map control after adding the namespace and placing the control. I'm using the provided VS 2010 Express version that comes with the Win Mobile 7 SDK and have just used the New Project - Windows Phone Application template. When I try to build I get two warnings related to the Microsoft.Maps.MapControl dll's. Warning 1 The primary reference "Microsoft.Maps.MapControl, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e" which could not be resolved in the currently targeted framework. "Silverlight,Version=v4.0,Profile=WindowsPhone". To resolve this problem, either remove the reference "Microsoft.Maps.MapControl, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e". Warning 2 The primary reference "Microsoft.Maps.MapControl.Common, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e" which could not be resolved in the currently targeted framework. "Silverlight,Version=v4.0,Profile=WindowsPhone". To resolve this problem, either remove the reference "Microsoft.Maps.MapControl.Common, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e". I'm leaning towards some way of adding the System.Windows.Browser to the targeted framework version. But I'm not even sure if that is possible. To be more specific; I'm looking for a way to get the Silverlight Maps Control up on a Windows Phone 7 series application. If possible. Thanks.

  • ViewPager + recycling views?

    - by user291701
    I'd like to create a gallery of photos that swipe left and right. At first I took a look at Gallery, but it's marked as deprecated. http://developer.android.com/reference/android/widget/Gallery.html We're told to try ViewPager instead. But the PagerAdapter class doesn't handle recycling of views for us (like a standard ListView), does it? http://developer.android.com/reference/android/support/v4/view/PagerAdapter.html Is it up to us to build the recycling mechanism? Thanks

  • Linking LAPACK/BLAS libraries

    - by Daniel Bremberg
    Background: I am working on a project written in a mix of C and Fortran 77 and now need to link the LAPACK/BLAS libraries to the project (all in a Linux environment). The LAPACK in question is version 3.2.1 (including BLAS) from netlib.org. The libraries were compiled using the top level Makefile (make lapacklib and make blaslib). Problem: During linking, error messages claimed that certain (not all) BLAS-routines called from LAPACK-routines were undefined. This gave me some headache but the problem was eventually solved when (in the Makefile) the order of appearance of the libraries to be linked was changed. Code: In the following, (a) gives errors while (b) does not. The linking is performed by (c). (a) LIBS = $(LAPACK)/blas_LINUX.a $(LAPACK)/lapack_LINUX.a (b) LIBS = $(LAPACK)/lapack_LINUX.a $(LAPACK)/blas_LINUX.a (c) gcc -Wall -O -o $@ project.o project.a $(LIBS) Question: What could be the reason for the undefined references of only some routines and what makes the order of appearance relevant?

  • Dynamic attributes with Rails and Mongoid

    - by japancheese
    Hello, I'm learning MongoDB through the Mongoid Ruby gem with Rails (Rails 3 beta 3), and I'm trying to come up with a way to create dynamic attributes on a model based on fields from another model, which I thought a schema-less database would be a good choice for. So for example, I'd have the models: class Account include Mongoid::Document field :name, :type => String field :token, :type => String field :info_needed, :type => Array embeds_many :members end class Member include Mongoid::Document embedded_in :account, :inverse_of => :members end I'm looking to take the "info_needed" attribute of the Account model and created dynamic attributes on the Member model based on what's inside. If club.info_needed was ["first_name", "last_name"], I'm trying to create a form that would save first_name and last_name attributes to the Member model. However, upon practice, I just keep getting "undefined method first_name=" errors on the Member model when trying to do this. I know MongoDB can handle dynamic attributes per record, but how can I get Mongoid to do this without an undefined method error?

    With the code below i get a CA2104 (DoNotDeclareReadOnlyMutableReferenceTypes) warning public readonly ReadOnlyCollection<char> IllegalChars; with part of the error message change the field to one that is an immutable reference type. If the reference type 'ReadOnlyCollection' is, in fact, immutable, exclude this message. I am sure ReadOnlyCollection is immutable but my question is is there a type can i use to not have this message appear?
