Gallio MbUnit and Team City problem

- by Bernard Larouche

I asked a question this morning about an integration problem between Gallio and Team City. I changed the msbuild file to use the proper syntax with the latest Gallio build script API. Thank you for that Jeff Brown but now when I tried to build the application on Team City I get the following error : An unexpected error occurred during execution of the Gallio task.[16:19:49]: [Project "CoderForTraders.msbuild.teamcity.patch.tcprojx" (RebuildSolution;RunTests target(s)):] C:\TeamCity\buildAgent\work\fa1d38b0af329d65\CoderForTraders.msbuild(9, 9): FilterParseException: Colon expected Here's line 9 : <Gallio IgnoreFailures="true" Filter="Type=SomeFixture" Files="@(TestFile)"> and here is the whole file : <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">  <UsingTask AssemblyFile="C:\Gallio\bin\Gallio.MSBuildTasks.dll" TaskName="Gallio" />  <ItemGroup> <TestFile Include="C:\_CBL\CBL\CoderForTraders\Source\trunk\UnitTest\DomainModel.Tests\bin\Debug\CBL.CoderForTraders.DomainModel.Tests.dll" /> </ItemGroup> <Target Name="RunTests"> <Gallio IgnoreFailures="true" Filter="Type=SomeFixture" Files="@(TestFile)">  <Output TaskParameter="ExitCode" PropertyName="ExitCode"/> </Gallio> <Error Text="Tests execution failed" Condition="'$(ExitCode)' != 0" /> </Target> <Target Name="RebuildSolution"> <Message Text="Starting to Build"/> <MSBuild Projects="CoderForTraders.sln" Properties="Configuration=Debug" Targets="Rebuild" /> </Target> </Project> Do you have an idea about the possible problem ?

Why do Asp.net timers/updatepanels leak memory and can it be fixed/worked around?

- by KallDrexx

I have built a suite of internal websites for our company to manage some of our processes. I have been noticing that these pages have massive memory leaks that cause the pages to be using well over 150mb of memory, which is ridiculous for a webpage that consists of a single form and a GridView that is displaying 7-10 rows of data at a time, sometimes with the data not changing for a whole day. This data does need to be refreshed on a semi-regular basis so that we always see the latest results and can act on them. After some testing it appears that the memory leak is extremely easy to reproduce, and very noticeable. I created a page with the following asp.net markup: <body> <form id="form1" runat="server"> <div> <asp:scriptmanager ID="Scriptmanager1" runat="server"></asp:scriptmanager> <asp:Timer ID="timer1" runat="server" Interval="1000" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> There is absolutely no code behind for this. This is the entirety of the page. Running this site in Chrome shows the memory usage shoot up to 25 megs in the span of 20-30 seconds. Leaving it running for a few minutes makes the memory go up to the 70 megs and such. Am I using timers and update panels wrong, or is this a pure Asp.net issue with no work around?

Why can't I send SOAP requests to Ebay finding API with this php?

- by Jay

This is my code: <?php error_reporting(E_ALL); //new instance of soapClient pointing to Ebay finding api $client = new SoapClient("http://developer.ebay.com/webservices/finding/latest/FindingService.wsdl"); //attach required parameters to soap message header $header_arr = array(); $header_arr[] = new SoapHeader("X-EBAY-SOA-MESSAGE-PROTOCOL", "SOAP11"); $header_arr[] = new SoapHeader("X-EBAY-SOA-SERVICE-NAME", "FindingService"); $header_arr[] = new SoapHeader("X-EBAY-SOA-OPERATION-NAME", "findItemsByKeywords"); $header_arr[] = new SoapHeader("X-EBAY-SOA-SERVICE-VERSION", "1.0.0"); $header_arr[] = new SoapHeader("X-EBAY-SOA-GLOBAL-ID", "EBAY-GB"); $header_arr[] = new SoapHeader("X-EBAY-SOA-SECURITY-APPNAME", "REMOVED"); $header_arr[] = new SoapHeader("X-EBAY-SOA-REQUEST-DATA-FORMAT", "XML"); $header_arr[] = new SoapHeader("X-EBAY-SOA-MESSAGE-PROTOCOL", "XML"); $test = $client->__setSoapHeaders($header_arr); $client->__setLocation("http://svcs.ebay.com/services/search/FindingService/v1");//endpoint $FindItemsByKeywordsRequest = array( "keywords" => "potter" ); $result = $client->__soapCall("findItemsByKeywords", $FindItemsByKeywordsRequest); //print_r($client->__getFunctions()); //print_r($client->__getTypes()); //print_r($result); ? And this is the error I receive: Fatal error: Uncaught SoapFault exception: [axis2ns2:Server] Missing SOA operation name header in C:\xampplite\htdocs\OOP\newfile.php:25 Stack trace: #0 C:\xampplite\htdocs\OOP\newfile.php(25): SoapClient-__soapCall('findItemsByKeyw...', Array) #1 {main} thrown in C:\xampplite\htdocs\OOP\newfile.php on line 25 It doesnt make sense, I have already set the operation name in the header of the request... Does anyone know what is wrong here?

Rails 3 - yield return or callback won't call in view <%= yield(:sidebar) || render('shared/sidebar'

- by rzar

Hey folks, I'm migrating a Website from Rails 2 (latest) to Rails 3 (beta2). Testing with Ruby 1.9.1p378 and Ruby 1.9.2dev (2010-04-05 trunk 27225) Stuck in a situation, i don't know which part will work well. Suspect yield is the problem, but don't know exactly. In my Layout Files I use the following technique quite often: app/views/layouts/application.html.erb: <%= yield(:sidebar) || render('shared/sidebar') %> For Example the partial look like: app/views/shared/_sidebar.html.erb: <p>Default sidebar Content. Bla Bla</p> Now it is time for the key part! In any view, I want to create a content_for block (optional). This can contain a pice of HTML etc. example below. If this block is set, the pice HTML inside should render in application.html.erb. If not, Rails should render the Partial at shared/_sidebar.html.erb on the right hand side. app/views/books/index.html.erb: <% content_for :sidebar do %> <strong>You have to read REWORK, a book from 37signals!</strong> <% end %> So you've got the idea. Hopefully. This technique worked well in any Rails 2.x Application. Now, in Rails 3 (beta2) only the yield Part is working. || render('shared/sidebar') The or side will not process by rails or maybe ruby. Thanks for input and time!

Hello EVery I am new to SQl. query to result in the following records. I have a table with records as c1 c2 c3 c4 c5 c6 1 John 2.3.2010 12:09:54 4 7 99 2 mike 2.3.2010 13:09:59 8 6 88 3 ahmad 2.3.2010 13:09:59 1 9 19 4 Jim 23.3.2010 16:35:14 4 5 99 5 run 23.3.2010 12:09:54 3 8 12 I want to fecth only records. i.e only 1 latest record per day. If both of them happen at the same time, sort by C1.so in 1&3 it should fetch 3. 3 ahmad 2.3.2010 14:09:59 1 9 19 4 Jim 23.3.2010 16:35:14 4 5 99 I have got a new problem in this. If i filter the records based on conditions the last record is missing. I tried many ways but still it is failing. Here update_log is my table. SELECT * FROM update_log t1 WHERE (t1.c3) = ( SELECT MAX(t2.c3) FROM update_log t2 WHERE DATEDIFF(dd,t2.c3, t1.c3) = 0 ) and t1.c3 > '02.03.2010' and t1.modified_at <= '22.03.2010' ORDER BY t1.c3 ASC. But i am not able to retrieve the record 4 Jim 23.3.2010 16:35:14 4 5 99 I dont know this query results in only 3 ahmad 2.3.2010 14:09:59 1 9 19 The format of the column c3 is datetime. I am pumping the data into the column as using $date = date("d.m.Y H:i",time()); -- simple date fetch of today. Another query that i tried for the same purpose. select * from (select convert(varchar(10), c3,104) as date, max(c3) as max_date, max(c1) as Nr from update_log group by convert(varchar(10), c3,104)) as t2 inner join update_log as t1 on (t2.max_date = t1.c3 and convert(varchar(10), c3,104) = date and t1.[c1]= Nr) WHERE t1.c3 >= '02.03.2010' and t1.c3 <= '16.04.2010' . I even tried this way..the same error last record is not coming..

XSLT 1.0 help with recursion logic

- by DashaLuna

Hello guys, I'm having troubles with the logic and would apprecite any help/tips. I have <Deposits> elements and <Receipts> elements. However there isn't any identification what receipt was paid toward what deposit. I am trying to update the <Deposits> elements with the following attributes: @DueAmont - the amount that is still due to pay @Status - whether it's paid, outstanding (partly paid) or due @ReceiptDate - the latest receipt's date that was paid towards this deposit Every deposit could be paid with one or more receipts. It also could happen, that 1 receipt could cover one or more deposits. For example. If there are 3 deposits: 500 100 450 That are paid with the following receipts: 200 100 250 I want to get the following info: Deposit 1 is fully paid (status=paid, dueAmount=0, receiptNum=3. Deposit 2 is partly paid (status=outstanding, dueAmount=50, receiptNum=3. Deposit 3 is not paid (status=due, dueAmount=450, receiptNum=NAN. I've added comments in the code explaining what I'm trying to do. I am staring at this code for the 3rd day now non stop - can't see what I'm doing wrong.

Microsoft Reporting 2005 and Report Viewer Report ASP.Net Session Has Expired on Load

- by ThaKidd

At my job, I have been tasked with fixing an error with our reporting server. That error is ASP.Net Session Has Expired. This error occurs when the Visual Studio ReportViewer 2005 Control attempts to load a report. We are trying to host this report to users hitting our Internet exposed Windows 2003 Server running IIS 6.0. The reportviewer control is attempting to load this report from a second server running Microsoft SQL 2005 w/Reporting Services. The SQL server is not exposed to the Internet. Here is the weird thing. This error never occurs on the development box. When it is transferred to the production IIS server, the error starts to occur. It only happens every time the report is first loaded. If the browser's refresh button is clicked 5-10 times, the report will finally load correctly. I have reproduced this same error on the latest version of Mozilla Firefox, IE 7, and IE 8. The report only takes 10-20 seconds to load. I have tried timeouts in the 300+ second range on the reporting server/iis production server. I have tried a few options like Async (which causes images not to load properly) and setting the session mode to iproc with a high timeout value in the Reporting Server's web.config. I have also tried using the reporting server's IP address in the report viewer's code instead of the server name. I plan on verifying a picture loading issue which I also read about tomorrow when I get into work. I am unsure what service packs Visual Studio 2005 and the MSSQL server are running. Was an update released to fix this problem that I could not find? Does anyone have a fix for this?

How to make sure Solr/Lucene won't die with java.lang.OutOfMemoryError?

- by taw

I'm really puzzled why it keeps dying with java.lang.OutOfMemoryError during indexing even though it has a few GBs of memory. Is there a fundamental reason why it needs manual tweaking of config files / jvm parameters instead of it just figuring out how much memory is available and limiting itself to that? No other programs except Solr ever have this kind of problem. Yes, I can keep tweaking JVM heap size every time such crashes happen, but this is all so backwards. Here's stack trace of the latest such crash in case it is relevant: SEVERE: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOfRange(Arrays.java:3209) at java.lang.String.<init>(String.java:216) at org.apache.lucene.index.TermBuffer.toTerm(TermBuffer.java:122) at org.apache.lucene.index.SegmentTermEnum.term(SegmentTermEnum.java:169) at org.apache.lucene.search.FieldCacheImpl$StringIndexCache.createValue(FieldCacheImpl.java:701) at org.apache.lucene.search.FieldCacheImpl$Cache.get(FieldCacheImpl.java:208) at org.apache.lucene.search.FieldCacheImpl.getStringIndex(FieldCacheImpl.java:676) at org.apache.lucene.search.FieldComparator$StringOrdValComparator.setNextReader(FieldComparator.java:667) at org.apache.lucene.search.TopFieldCollector$OneComparatorNonScoringCollector.setNextReader(TopFieldCollector.java:94) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:245) at org.apache.lucene.search.Searcher.search(Searcher.java:171) at org.apache.solr.search.SolrIndexSearcher.getDocListNC(SolrIndexSearcher.java:988) at org.apache.solr.search.SolrIndexSearcher.getDocListC(SolrIndexSearcher.java:884) at org.apache.solr.search.SolrIndexSearcher.search(SolrIndexSearcher.java:341) at org.apache.solr.handler.component.QueryComponent.process(QueryComponent.java:182) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:195) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1316) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:338) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:241) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619)

In need of help with setting up the open source library JFreeChart

- by ssbellows

I am having trouble with setting up the open source library JFreeChart for creating charts using Java. This is the process I have followed so far in trying to set it up: I downloaded the latest version from their download page http://sourceforge.net/projects/jfreechart/files/. I then unpacked the jfreechart-1.0.13.zip in the directory C:\JFreeChart\jfreechart-1.0.13\ on my system drive. In the unpacked directory there is a folder entitled "lib" which contains the packaged .jar files specified as necessary to use JFreeChart. I added the following directory to my classpath: C:\JFreeChart\jfreechart-1.0.13\lib\ I then created a simple program and added the line "import org.jfree.chart.*;" to see if it would compile with a package imported from JFreeChart. I navigated to the folder in which my sample program was contained and compiled with the following command: "javac -classpath C:\ Program.java" I was given the following error: "package org.jfree.chart does not exist" Could someone please give me some input as to what I have done incorrectly in this setup process? This is the first time I've tried using an open source library, so I don't have any prior experience to go on myself. Thank you very much in advance.

Malloc corrupting already malloc'd memory in C

- by Kyte

I'm currently helping a friend debug a program of his, which includes linked lists. His list structure is pretty simple: typedef struct nodo{ int cantUnos; char* numBin; struct nodo* sig; }Nodo; We've got the following code snippet: void insNodo(Nodo** lista, char* auxBin, int auxCantUnos){ printf("*******Insertando\n"); int i; if (*lista) printf("DecInt*%p->%p\n", *lista, (*lista)->sig); Nodo* insert = (Nodo*)malloc(sizeof(Nodo*)); if (*lista) printf("Malloc*%p->%p\n", *lista, (*lista)->sig); insert->cantUnos = auxCantUnos; insert->numBin = (char*)malloc(strlen(auxBin)*sizeof(char)); for(i=0 ; i<strlen(auxBin) ; i++) insert->numBin[i] = auxBin[i]; insert-numBin[i] = '\0'; insert-sig = NULL; Nodo* aux; [etc] (The lines with extra indentation were my addition for debug purposes) This yields me the following: *******Insertando DecInt*00341098->00000000 Malloc*00341098->2832B6EE (*lista)-sig is previously and deliberately set as NULL, which checks out until here, and fixed a potential buffer overflow (he'd forgotten to copy the NULL-terminator in insert-numBin). I can't think of a single reason why'd that happen, nor I've got any idea on what else should I provide as further info. (Compiling on latest stable MinGW under fully-patched Windows 7, friend's using MinGW under Windows XP. On my machine, at least, in only happens when GDB's not attached.) Any ideas? Suggestions? Possible exorcism techniques? (Current hack is copying the sig pointer to a temp variable and restore it after malloc. It breaks anyways. Turns out the 2nd malloc corrupts it too. Interestingly enough, it resets sig to the exact same value as the first one).

Remote DLL Registration without access to HKEY_CLASSES_ROOT

- by mohlsen

We have a legacy VB6 application that updates itself on startup by pulling down the latest files and registering the COM components. This works for both local (regsvr32) ActiveX COM Components and remote (clireg32) ActiveX COM components registered in COM+ on another machine. New requirements are preventing us from writing to HKEY_LOACL_MACHINE (HKLM) for security reasons, which is what obviously happens by default when calling regsvr32 and clireg32. We have come up with an way to register the local COM componet under HKEY_CURRENT_USER\Software\Classes (HKCU) using the RegOverridePredefKey Windows API method. This works by redirecting the inserts into the registry to the HKCU location. Then when the COM components are instantiated, windows first looks to HKCU before looking for component information in HKLM. This replaces what regsvr32 is doing. The problem we are experiencing at this time is when we attempt to register VBR / TLB using clireg32, this registration process also adds registration keys to HKEY_LOACL_MACHINE. Is there a way to redirect clireg32.exe to register component is HKEY_CURRENT_USER? Are there any other methods that would allow us to register these COM+ components on clients machine with limited security access? Our only solution at this time would be to manually write the registration information to the registry, but that is not ideal and would be a maint issue.

Add autoFill capabilities to jQuery-UI 1.8.1

here's what I currently have, unfortunately I cannot seem to figure out how to get autoFill to work with jQuery-UI...

Does anyone know how to extract the ID out of the autocomplete when you don't actually select the field?

I have tried playing with the path on line 48, nothing changes, here is what line 48-50 looks like: Line 48: die "$BASE/lib does not exist" unless -d "$BASE/lib"; Line 49: die "$BASE/include does not exist" unless -d "$BASE/include"; Line 50: die "lid.h is missing in $BASE/include" unless -e "$BASE/includ/lid.h"; The variable $BASE is declared as this: $BASE = "/opt/ls/" if ($^O eq "linux" or $^O eq "solaris"); $BASE = "/usr/local/" if ($^O eq "freebsd"); $BASE = $ENV{LID_BASE_DIR} if (defined $ENV{LID_BASE_DIR}); Now the perl program I am trying to write simply look like this (just my base): #!/usr/bin/perl use Lingua::LinkParser; use strict; print "Hello world!\n"; When I run this trying to use Lingua, here is my error: [root@csisl27 assign4]# ./perl_parser_1.pl Can't locate Lingua/LinkParser.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.10.0/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.10.0 /usr/lib/perl5/vendor_perl/5.10.0/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.10.0 /usr/lib/perl5/5.10.0/x86_64-linux-thread-multi /usr/lib/perl5/5.10.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl .) at ./perl_parser_1.pl line 3.

In .net what are the difference between Eventlog and ManagementObject for retriving logs from remote

- by Mitesh Patel

I have found out following two ways for getting Application Event log entries from remote server. 1. Using EventLog object string logType = "Application"; EventLog ev = new EventLog(logType,"rspl200"); EventLogEntryCollection evColl = ev.Entries 2. Using ManagementObjectSearcher object ConnectionOptions co = new ConnectionOptions(); co.Username = "testA"; co.Password = "testA"; ManagementScope scope = new ManagementScope(@"\" + "machineName"+ @"\root\cimv2", co); scope.Connect(); SelectQuery query = new SelectQuery(@"select * from Win32_NtLogEvent"); EnumerationOptions opt = new EnumerationOptions(); opt.BlockSize = 1000; using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query,opt)) { foreach (ManagementObject mo in searcher.Get()) { // write down log entries Console.Writeline(mo["EventCode"]); } } I can easily get remote eventlog using method #1 (Using EventLog object) without any security access denied exception. But using method #2 (Using ManagementObjectSearcher object) i get access denied exception. Actually I want remote event log (only application and also latest log not all application logs) to be displayed in treeview like below - ServerName - Logs + Error + Information + Warning Can anybody help me in this to find out best way from this or any other? Also the main thing is that user who reads remote logs may be in different domain than server. Thanks Mitesh Patel

Rails apps blew up on mediatemple's (dv) server

- by BandsOnABudget

i managed to fix this issue but i wanted to document it here for any others whom might have similar problems. I'm running a mediatemple (dv) rage server. monit started sending me alerts that i was having resource limitations on the server. logged into plesk and the CPU was pinned at 99.9%. Rebooted the server, catastrophe avoided... Not quite - all my rails apps were not loading My Setup ruby 1.8.6 Rails 2.3.5 w/ passenger installed as an apache module. I noticed a defunct ruby process so i killed and rebooted the server but runby continued to come back as defunct. Started trolling thru the apache log and i saw errors irt updating rubygems. i updated to the latest but then continued to get gem errors. Basically, I had to go thru all my apps and update any gems manually, reboot apache, and all was restored. Not really sure the cause of the issue but wanted to note it for posterity. Anybody else in the community ever have similar issues???

WPF DataGrid inside Accordion height issue

- by LucasS

I am using the latest WPF Toolkit but am running into a height issue when I have a large record set bound into a datagrid inside an AccordionItem item. The height of the Accordion itself scales nicely but the datagrid inside the accordion control doesn't get get a scrollbar or get constrained in any way so the records are hidden. I know that I am most probably missing something very simple (like a binding from the datagrid's height property to the Accordion but that seems messy) here is a cut down version of the code (and yes, this has the same problem if you bind in a big recordset) ... </layouttoolkit:AccordionItem> <layouttoolkit:AccordionItem Header="grid 2"> <dg:DataGrid AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False" SelectionMode="Single"> ... </dg:DataGrid.Columns> </dg:DataGrid> </layouttoolkit:AccordionItem> <layouttoolkit:AccordionItem Header="grid 3"> <dg:DataGrid AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False" SelectionMode="Single"> ... </dg:DataGrid.Columns> </dg:DataGrid> </layouttoolkit:AccordionItem> </layouttoolkit:Accordion> </UserControl>

What's are the best readings to start using WPF instead of WinForms?

- by Ivan

Keeping in mind what CannibalSmith once said - "All the answers are saying "WPF is different". That's a huge understatement. You not only have to learn lots of new stuff - you must forget everything you've learned from Forms. It's a completely new way of doing UI." .. and having many years of experience with visual Windows desktop applications development (VB6, Borland C++ Builder VCL, WinForms) (which is hard to forget), how do I quickly move to developing to say well-formed WPF applications with Visual Studio? I don't need boozy-woozy graphics to give my app look and feel of a Hollywood blockbuster or a million dollar pyjamas. I always loved tidiness of standard Windows common controls and UI design guidelines, end even more I enjoyed them under Vista Glass Aero Graphite sauce. I am perfectly satisfied with WinForms but I want to my applications to be built of the most efficient and up-to-date standard technologies and architectured according to the most efficient and flexible patterns of today and tomorrow, leveraging interface-based integration and functionality reuse and to take all advantages of modern hardware and APIs to maximize performance, usability, reliability, maintainability, extensibility, etc. I very much like the idea of separating view, logic and data, letting a view to take all advantages of the platform (may it run as a web browser applet on a thin client or as a desktop application on a PC with a latest GPU), letting logic be reused, parallelized and seamlessly evolve, storing data in a well structured format in a right place. But... while moving from VB6 to Borland C++ Builder was very easy (no books/tutorials needed to turn it on and start working) (assuming I already knew C++), moving from BCB to WinForms was the same seamless, it does not seem any obvious to me how to do with WPF. So how do I best convert myself from a WinForms developer into a right-way thinking and doing WPF developer?

Fluent config not generating mapping files

- by rboarman

Hello, I am trying to get Fluent nHibernate to generate mappings so I can take a look at the files and the sql. My code is based on this post and on what I can glean from the documentation. http://stackoverflow.com/questions/1375146/fluent-mapping-entities-and-classmaps-in-different-assemblies I am using the latest code from git. Here’s my config code: Configuration cfg = new Configuration(); var ft = Fluently.Configure(cfg); //DbConnection by fluent ft.Database ( MsSqlConfiguration .MsSql2008 .ConnectionString("……") .ShowSql() .UseReflectionOptimizer() ); //get mapping files. ft.Mappings(m => { //set up the mapping locations m.FluentMappings.AddFromAssemblyOf<Entity>() .ExportTo(@"C:\temp"); m.Apply(cfg); }); I also tried: var sessionFactory = Fluently.Configure() .Database(MsSqlConfiguration .MsSql2008 .ShowSql() .ConnectionString(“……")) .Mappings(p => p.FluentMappings .AddFromAssemblyOf<Entity>() .ExportTo(@"c:\temp\")) .BuildSessionFactory(); I have verified that the connection string is correct. The issue is that no mapping files show up in the ExportTo folder and no sql code shows up in the output window or in the log file. No errors or exceptions are generated either. I have no idea where to go from here. Thank you in advance. Rick

Stuck on preserving config file in WIX major upgrade!

- by Joshua

ARGH! Wix is driving me crazy. So, of course I have seen the many posts both here on stackoverflow and elsewhere about WiX and major upgrades. I inherited this software project using WiX and am releasing a new version. I need this new version to leave ONLY the one configuration file if it's present, and replace everything else. This installer works EXCEPT no matter what I have done so far, the new XML file replaces the old on every install. Even attempting to use NeverOverwrite="yes" and even trying and messing back and forth with OnlyDetect="no"! I am simply stuck and humbly request a little guidance. The file that needs to be preserved is called SETTINGS.XML and is in the All Users-ApplicationData directory.

A problem of trying to implement scrolling inertia with jQuery

- by gargantaun

I'm trying to add some iPhone style scrolling inertia to a web page that will only be viewed on the iPad. I have the scrolling working in one direction (scrollLeft), but it doesn't work in the other direction. It's a pretty simple function function onTouchEnd(event){ event.preventDefault(); inertia = (oldMoveX - touchMoveX); // Inertia Stuff if( Math.abs(inertia) > 10 ){ $("#feedback").html(inertia); $("#container").animate({ 'scrollLeft': $("#container").scrollLeft() + (inertia * 10) }, inertia * 20); }else{ $("#feedback").html("No Inertia"); } } I've bound it to the 'touchend' event on the body. The intertia is the difference betweent he old moveX position and the latest moveX position when a touch ends. I then try to animate the scrollLeft property of a div that contains a bunch of thumbnails. As I've said, this works when scrolling to the left, but not when scrolling to the right. You can view the full source code (all in one page) or test it on your iPhone or iPad (or in the simulator) here http://www.appliedworks.co.uk/files/times/swipegal.html Any ideas?

Should DAL always return business objects in MVP

- by Chathuranga

In Model View Presenter (MVP) pattern, it is said that our DAL always should returns business models. But let's say if I want to get just a number from database like the last ClientID (the latest clients ID) which is a string, should my DAL method returns a ClientInfo object which has about 10 other fields as well like ClientName, Address etc.? If I want to get a list of business objects from my DAL, is it acceptable to do it as follows or better to get a DataTable from DAL and then in the applications BLL, converts it a List? public List<Employee> GetNewEmployees() { string selectStatement = "SELECT Employee.Emp_ID, Employee.Initials + ' ' + Employee.Surname AS Name,..."; using (SqlConnection sqlConnection = new SqlConnection(db.GetConnectionString)) { using (SqlCommand sqlCommand = new SqlCommand(selectStatement, sqlConnection)) { sqlConnection.Open(); using (SqlDataReader dataReader = sqlCommand.ExecuteReader()) { List<Employee> list = new List<Employee>(); while (dataReader.Read()) { list.Add ( new EpfEtfMaster { EmployeeID = (int) dataReader ["emp_id"], EmployeeName = (string) dataReader ["Name"], AppointmentDate = (DateTime) dataReader["appointment_date"], }); } return list; } } } }

Test Results window in VS2008 not showing results

- by TimK

I have an existing solution that has been working for a long time, containing around 600 tests in a couple of test projects. I recently moved to a new PC - it's Win7-x64, and I installed a fresh copy of VS2008. When I first opened the solution on the new machine, the Test List Editor was completely empty. Trying to create a new test list caused the editor to refresh, and now it shows my test lists, but they're acting funny. I can select tests in the lists, and run them, but the results window doesn't usually update automatically to show the results of the latest test. It has done this when running a single test a couple of times, but even that is not consistent. The only way I can view the results is by manually going to the Test Runs window and connecting to individual test runs. When I do that, the results show up in the results list, but I can't check them to re-run the failed tests - the check boxes are all disabled. I guess I should describe the way it used to work, in case that was unusual - I used to select some tests from the Test Lists window, tell it to run them, and the results window would clear itself, and then display the results from the current run. I could then check any tests that I wanted to re-run, and use the run/debug button in the results window to do so. Any ideas what's going on here?

Using jQuery delay() with separate elements

- by boomturn

I want to fake a simple animation on page load by sequentially revealing several pngs, each appearing instantly but with unique, precisely timed delay before the next one. Using the latest version of jQuery (1.4.2 at writing), which provides a delay method. My first (braindead) impulse was: $('#image1').show('fast').delay(800); $('#image2').show('fast').delay(1200); $('#image3').show('fast'); Of course all come up simultaneously. jQuery doc examples refer to a single item being chained, not handling multiple items. OK... try again using nested callbacks from show(): $('#image1').show('fast', function() { $('#image2').show('fast', function() { $('#image3').show('fast', function() { }); }); }); Looks ugly (imagine doing 10, also wonder what processor hit would be) but hey, it works sequentially! Without delay though. So... chain delay() after show() using a callback function from it (not even sure if it supports one): $('#image1').show('fast').delay(800, function() { $('#image2').show('fast').delay(1200, function() { $('#image3').show('fast'); }); }); Hm. Opposite result of what I thought might happen: the callback works, but still no delay. So... should I be using some combination of queue and delay instead of nested callbacks? jQuery doc examples for queue again only use one element for example. Guessing this would involve using a custom queue, but am uncertain how to implement this. Or maybe I'm missing a simple way? (For a simple problem!)

What is more viable to use? Javascript libraries or UI Programming tools?

- by Haresh Karkar

What is more viable to use:- Javascript Libraries: YUI, jQuery, ExtJs OR UI Programming tools: GWT, ExtGWT, SmartGWT It has become very difficult to choose between them as they are constantly increasing their capabilities to meet newer requirements. We all know the power of jQuery in UI manipulations. The latest news from Microsoft about jQuery being officially part of .Net developr’s toolkit will definitely make jQuery a preferred choice against other JavaScript libraries [See link: http://weblogs.asp.net/scottgu/archive/2008/09/28/jquery-and-microsoft.aspx]. But on the other hand, GWT is building a framework which could be used on client as well as on the sever side. This is definitely going to make developers’ life easy as it does not require developer to be an expert in browser quirks, XMLHttpRequest, and JavaScript in order to develop high-performance web applications. It includes SDK (Java API libraries, compiler, and development server which allows to write client-side applications in Java and deploy them as JavaScript), Speed Tracer and plug-in for Eclipse. GWT is used by many products like Google Wave and AdWords. So question is still un-answered, what is more viable to use? Any thoughts?
