• How to set default values to the properties of dynamically loaded types at runtime for XML serializa

  - by Erkan Y.

  I need to serialize dynamically loaded types' classes using XMLSerializer. When using XML serializer non initialized values are not being serialized. I dont have control over the assemblies I am working with so can not use XML attributes for specifying default values on properties. So I think I need to set all properties and sub properties to their default values recursively and then serialize. ( Please let me know if there is any better way ) Followed this : Activator.CreateInstance(propType); but above line complains about not having a parameterless constructor for some types. Tried this : subObject = FormatterServices.GetUninitializedObject(propType); but this one gives an error "value was invalid" with no inner exception. Please let me know if you need any further information.

• SharePoint Documents Library - Change "Document Created By" field

  - by yellowblood

  Hello, I have a code that changes the username in various SharePoint lists, mostly by the "Author" column. It all works fine on normal lists, but it doesn't seem to work on the "Shared Documents" list which is a document library. Whether I change the username in "Created By" or "Document Created By", the change doesn't seem to take effect. The item.Update command doesn't throw any exception, but it clearly doesn't update the field(s). What can I do if I want to change this field through code? Thanks

• Why is there so much poorly indented code out there?

  - by dsimcha

  The more I browse the code to open source projects in languages that aren't Python, the more I realize that it seems a lot of programmers don't believe in proper indentation. (I won't mention any projects specifically to avoid having anyone take this question too personally.) Usually code is indented, but in a way just different enough from the standard style that it drives me crazy, especially in old/crufty code. I've noticed that when I write in C-like languages, I tend to indent correctly as religiously as when I'm writing in Python, with the exception of debugging code that I actually want to stick out like a sore thumb. Given how easy it is with a modern IDE to fix incorrect indentation, what are some rationales for not religiously keeping indentation in sync with braces?

• What is the easiest way to loop through a folder of files in C#?

  - by badpanda

  I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

• Why can't I find DataTemplates in merged resource dictionaries?

  - by dthrasher

  In my MainWindow.xaml, I have the following reference to a ResourceDictionary: <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> In MainSkin.xaml, I define a datatemplate: <DataTemplate x:Key="TagTemplate"> ... </DataTemplate> Deeper within my application, I attempt to use this data template: <ContentControl DataContext="{Binding Tag}" ContentTemplate="{StaticResource TagTemplate}"/> The code compiles successfully, but when I attempt to load a Page or UserControl that contains this StaticResource, I get an exception saying that the TagTemplate can't be found. What am I doing wrong?

• Linq ChangeConflictException occurs when submitting DataContext changes

  - by Alex

  System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n) This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right? How can I fix it? Update I just debugged the error and found the following: Table name: dbo.Stats current value: 9852039 original value: 9852038 database value: 9852039 The Stats table is updated constantly. So how can I still make LINQ save the changes. With "classical" SQL Server access through SqlDataCommand I never had problems like that.

  Hi! I have a aspx file that suppose to write to a file in the server while loading. On the local machine it works fine, but when i deploy it to a live server it gives me an exception "Access to the path 'd:\DZHosts\LocalUser\asafz83\www.asafz83.somee.com\lala.htm' is denied." WHen i asked my serverAdmin for the reason - he told me to remove any impersonation from my web.config file. Well, my web.config file doesn't contain any impersonation, so i'm really confused: What can i do in order for this sealy-stupid application to work? thanks!

• How to estimate memory need by XPathDocument for a specific xml file

  - by bill seacham

  Is there any way to estimate the memory requirement for creating an XpathDocument instance based on the file size of the xml? XpathDocument xdoc = new XpathDocument(xmlfile); Is there any way to programmatically stop the process of creating the XpathDocument if memory drops to a very low level? Since it loads the entire xml into memory, it would be nice to know ahead of time if the xml is too big. What I have found is that when I create a new XpathDocument with a big xml file, an outofmemory exception is never fired, but that the process slows to a crawl, only 5 Mb of memory remains a available and the Task Manager reports it is not responding. This happened with a 266 Mb xml file when there was 584 Mb of ram. I was able to load a 150 Mb file with no problems in 18. After loading the xml, I want to do xpath queries using an XpathNavigator and an XpathNodeIterator. I am using .net 2.0, xp sp3.

• Well....a ghost lives in my server...

  - by tsgiannis

  Hello to every body and greetings from Greece I have a rather unusual situation and i am running out of ideas. I have this old server (IBM x205 - P4 2.4Ghz,3xSCSI 36gb) and i was about a year ago i decided to use it as an additional domain controller,fax & file server...for this task i had a Delock 70154 SATA card along with 2x320 SATA II HDDs Everything was going super smoothly until about 3 weeks ago. I was on a trip and i was informermed when i got back that the server was found frozen...well i considered it was a glitch since a simple powerdown power up fixed everything.Again 2 weeks ago another freeze situation....it got suspicious but again power down power up everything was running.... Last again it frozen and when i power it up it came with a message that the Domain services could not start due to NTDS corruption....booting in safe mode revealed that there was an issue with the SATA Raid (degraded). After a lot of searching i degraded the server...cleaned Active Directory and pulled both HDDs out (one of these was really BAD ) and recovered my files (i had some problems with ho Delock handles the redudant HDD). Right now my server is vanilla simple...with only what the factory installed and here is where the fun begins. Everyday when i arrive at the office i find this particular machine dead..and i mean total dead...just a black screen and nothing else...the cpu fan is working ,the psu is working .keyboard and mouse are dead(they also lock my kvm) ...network is dead.... the machine is DEAD. I power it down forcilly ...i power it up and for the 8 hours i am in the office it works,either idling or running some kind of diagnostic...when i leave the office after some time..it maybe half an hour ...it maybe 4 hours the machine dies...at least this is the information the event log shows (" the previous shutdown at xx:xx:xx was unexpected) Well i must admit i am runnig out of ideas.... I have tried Memtest....nothing Passmark burn in test.....nothing Carefull study of the event log.....nothing Set Instead of restart..BSOD....nothing Power sceheme to sleep...all set to never. i know there are a lot of other tools that heavily stress a machine like occt but .... the machine is old...today i will give them a try nevertheless ..... One idea is to reformat it...but ... i really like to find what is causing this because i could get to a situation that everything is working for a while and kaboom...one day again is dying.. I really need a helping hand and every opinion / idea is well welcomed.... iknow the obvious solution is to never leave the office but....i have a life...sory server...:) P.S this situation with the machine dying some time after is going on for about one week...everyday i would set either the RAID to rebuild....or to copy/recover files and while everythig was working

• Create LINQ to entities OrderBy expression on the fly

  - by AyKarsi

  I'm trying to add the orderby expression on the fly. But when the query below is executed I get the following exception: System.NotSupportedException: Unable to create a constant value of type 'Closure type'. Only primitive types ('such as Int32, String, and Guid') are supported in this context. The strange thing is, I am query exactly those primitive types only. string sortBy = HttpContext.Current.Request.QueryString["sidx"]; ParameterExpression prm = Expression.Parameter(typeof(buskerPosting), "posting"); Expression orderByProperty = Expression.Property(prm, sortBy); // get the paged records IQueryable<PostingListItemDto> query = (from posting in be.buskerPosting where posting.buskerAccount.cmsMember.nodeId == m.Id orderby orderByProperty //orderby posting.Created select new PostingListItemDto { Set = posting }).Skip<PostingListItemDto>((page - 1) * pageSize).Take<PostingListItemDto>(pageSize); Hope somebody can shed some light on this!

• EntityFramework WCF issue

  - by Andres Blanco

  Right now i'm doing some tests involving entityFramework and WCF. As I understand, the EntityObjects generated are DataContracts and so, they can be serialized to the client. In my example I have a "Country" entity wich has 1 "Currency" as a property, when I get a Country and try to send it to the client, it throws an exception saying the data cant be written. But, the thing is, if I Get a Currency (which has a collection of Countries) and dont load its countries, it does work. The client gets all the entities. So, as a summary: - I have an entity with another entity as a property and cant be serialized. - I have another entity with an empty list of properties and it is successfully serialized. Any ideas on how to make it work?

  Could not load file or assembly 'Payflow_dotNET_2.0' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) I tried to reference the payflow SDK and got this error.But I am no longer trying to reference it. I have removed all references to this dll. and Now I am just trying to get the project to start in VS but I still get this error. I am not trying to add the dll anymore.If i have removed the reference to this, why am I still getting this error? How can I remove anything else that may still be causing my program to look for this file? Thanks!
