• Moving soon, fiancee has new job: how to transition?

  - by Anonymous

  I've found myself in a sort of conundrum lately and I figured Stack Overflow would be the place to ask this question. I normally post under my personal account here, but I'm writing in anonymously this time so as to make sure my co-workers don't find out too early that I'll be leaving them behind in a few months. My fiancee just landed a great software development job at a very large, stable company. She'll be starting after she graduates and just after we get married (May to June-ish). Her compensation and benefits package will be more than enough to take care of both of us, so I agreed to step down from my current position so we could move to a larger city with more opportunities. I'll probably take a few weeks off to decompress, but I don't want to stay unemployed very long. Since there will be less pressure on me to bring home a second income though, we're not as adverse to risk as we normally would be. I'm currently debating whether to eventually seek employment at a small company, a larger company, do contract work, or do something else entirely. I haven't been in the software development business long (2-3 years plus some small personal projects), but I've seen what things can be like at a startup (my first job) and at a more established, mid-sized business (my current job). Most importantly what I'm looking for out of a new employment opportunity is challenge and variety. Does this situation describe anyone on SO? If so, what did you do/what are you doing? How is it working out for you? Programming is a pleasure as well as a career skill for me, so I want to make sure it stays that way. Thanks to all in advance for any responses.

• NGINX - CORS error affecting only Firefox

  - by wiherek

  this is an issue with Nginx that affects only firefox. I have this config: http://pastebin.com/q6Yeqxv9 upstream connect { server 127.0.0.1:8080; } server { server_name admin.example.com www.admin.example.com; listen 80; return 301 https://admin.example.com$request_uri; } server { listen 80; server_name ankieta.example.com www.ankieta.example.com; add_header Access-Control-Allow-Origin $http_origin; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, PATCH, DELETE'; add_header 'Access-Control-Allow-Credentials' 'true'; add_header 'Access-Control-Allow-Headers' 'Access-Control-Request-Method,Access-Control-Request-Headers,Cache,Pragma,Authorization,Accept,Accept-Encoding,Accept-Language,Host,Referer,Content-Length,Origin,DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; return 301 https://ankieta.example.com$request_uri; } server { server_name admin.example.com; listen 443 ssl; ssl_certificate /srv/ssl/14182263.pem; ssl_certificate_key /srv/ssl/admin_i_ankieta.example.com.key; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM; location / { proxy_pass http://connect; } } server { server_name ankieta.example.com; listen 443 ssl; ssl_certificate /srv/ssl/14182263.pem; ssl_certificate_key /srv/ssl/admin_i_ankieta.example.com.key; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM; root /srv/limesurvey; index index.php; add_header 'Access-Control-Allow-Origin' $http_origin; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, PATCH, DELETE'; add_header 'Access-Control-Allow-Credentials' 'true'; add_header 'Access-Control-Allow-Headers' 'Access-Control-Request-Method,Access-Control-Request-Headers,Cache,Pragma,Authorization,Accept,Accept-Encoding,Accept-Language,Host,Referer,Content-Length,Origin,DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; client_max_body_size 4M; location / { try_files $uri $uri/ /index.php?q=$uri&$args; } location ~ /*.php$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini include fastcgi_params; fastcgi_param SCRIPT_FILENAME /srv/limesurvey$fastcgi_script_name; # fastcgi_param HTTPS $https; fastcgi_intercept_errors on; fastcgi_pass 127.0.0.1:9000; } location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires max; log_not_found off; } } this is basically an AngularJS app and a PHP app (LimeSurvey), served under two different domains by the same webserver (Nginx). AngularJS is in fact served by ConnectJS, which is proxied to by Nginx (ConnectJS listens only on localhost). In Firefox console I get this: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://ankieta.example.com/admin/remotecontrol. This can be fixed by moving the resource to the same domain or enabling CORS. which of course is annoying. Other browsers work fine (Chrome, IE). Any suggestions on this?

• "The calling thread cannot access this object because a different thread owns it." While using Dispa

  - by Sdry

  I have an application, that I want to load additional xaml files, being resourcedictionaries controling the style of the application. Yet when trying to add a loaded ResourceDictionary to the mergeddictionaries I get an InvalidOperationException saying "The calling thread cannot access this object because a different thread owns it." at a point where I am not even using multiple threads. The application contains a usercontrol which loads the xaml file through a background worker, adding the loaded ResourceDictionaries to an Observablecollection. When I pass on a selected theme(=ResourceDictionary) to a function in the mainwindow of the application, it goes wrong. public void LoadTheme(Theme theme) {//sdry 2010-4-22 if(theme !=null){ this._dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() => { MessageBox.Show("SKIN TEST: " + theme.Name); //> oke #if (SHOWDEBUGINFO) _selectedTheme = theme.Name; //>oke #endif Application.Current.Resources.MergedDictionaries.Clear(); //>oke Application.Current.Resources.MergedDictionaries.Add(theme.ResourceDictionary); //> InvalidOperationException //the theme object has a property named ResourceDictionary of type ResourceDictionary containing the loaded xaml })); } } My first reaction was to use the Disatcher.Invoke, even not knowing how I would not be on the gui thread, which doesn't solve a thing. So maybe my loaded theme belongs to a different thread ? but its originating from a property of a usercontrol, which should be the same thread. And its accesable untill trying to use the ResourceDictionary. This makes me confused, and not very aware of how to proceed, any help is appreciated.

• How to access WCF RIA service from Windows Service?

  - by Duncan Bayne

  I have a functioning SL4 application; inside the ClientBin directory I have an .svc file that describes my service: <% @ServiceHost Service="MyApp.Services.MyServiceFactory="System.ServiceModel.DomainServices.Hosting.DomainServiceHostFactory" %> When I browse to http://localhost:52878/ClientBin/MyApp-Services-MyService.svc I see the following: "You have created a service. To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://localhost:52878/ClientBin/MyApp-Services-MyService.svc?wsdl" I want to access that service from a Windows Service application. My understanding is that I need to enable SOAP end-points in order to make this happen. So, I add the following to my web.config file: <domainServices> <endpoints> <add name="soap" type="System.ServiceModel.DomainServices.Hosting.SoapXmlEndpointFactory, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </endpoints> </domainServices> Firstly, Intellisense complains about the presence of the tag, saying "The element system.ServiceModel has invalid child element domainServices." Secondly, the aforementioned Silverlight application stops working, presumably because this change breaks the underlying web services. Thirdly, it appears that the System.ServiceModel.DomainServices.Hosting assembly doesn't actually contain the SoapXmlEndpointFactory type; if I try to browse to the service after adding the above to web.config I see: "Could not load type 'System.ServiceModel.DomainServices.Hosting.SoapXmlEndpointFactory' from assembly 'System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'." If I inspect the assembly using Reflector, I see that it contains the DomainServiceEndpointFactory and PoxBinaryEndpointFactory types, but no SoapXmlEndpointFactory. Could someone please let me know what I'm doing wrong? I can't believe that it should be this hard to simply consume a WCF RIA service in something other than a Silverlight application! Yours, Duncan Bayne

• Access to DataTemplate Control of WPF Toolkit DataGridCell at Runtime, How?

  - by LukePet

  I have a DataGrid defined with WPF Toolkit. The CellEditingTemplate of this DataGrid is associated at runtime with a custom function that build a FrameworkElementFactory element. Now I have to access to control that is inserted inside DataTemplate of CellEditingTempleta, but I do not know how to do. On web I found a useful ListView Helper... public static class ListViewHelper { public static FrameworkElement GetElementFromCellTemplate(ListView listView, Int32 column, Int32 row, String name) { if (row >= listView.Items.Count || row < 0) { throw new ArgumentOutOfRangeException("row"); } GridView gridView = listView.View as GridView; if (gridView == null) { return null; } if (column >= gridView.Columns.Count || column < 0) { throw new ArgumentOutOfRangeException("column"); } ListViewItem item = listView.ItemContainerGenerator.ContainerFromItem(listView.Items[row]) as ListViewItem; if (item != null) { GridViewRowPresenter rowPresenter = GetFrameworkElementByName<GridViewRowPresenter>(item); if (rowPresenter != null) { ContentPresenter templatedParent = VisualTreeHelper.GetChild(rowPresenter, column) as ContentPresenter; DataTemplate dataTemplate = gridView.Columns[column].CellTemplate; if (dataTemplate != null && templatedParent != null) { return dataTemplate.FindName(name, templatedParent) as FrameworkElement; } } } return null; } private static T GetFrameworkElementByName<T>(FrameworkElement referenceElement) where T : FrameworkElement { FrameworkElement child = null; for (Int32 i = 0; i < VisualTreeHelper.GetChildrenCount(referenceElement); i++) { child = VisualTreeHelper.GetChild(referenceElement, i) as FrameworkElement; System.Diagnostics.Debug.WriteLine(child); if (child != null && child.GetType() == typeof(T)) { break; } else if (child != null) { child = GetFrameworkElementByName<T>(child); if (child != null && child.GetType() == typeof(T)) { break; } } } return child as T; } } this code work with the ListView object but not with the DataGrid object. How can use something like this in DataGrid?

• What could be causing a "Cannot access a disposed object" error in WCF?

  - by Nima

  I am using the following code: private WSHttpBinding ws; private EndpointAddress Srv_Login_EndPoint; private ChannelFactory<Srv_Login.Srv_ILogin> Srv_LoginChannelFactory; private Srv_Login.Srv_ILogin LoginService; The Login is my constructor: public Login() { InitializeComponent(); ws = new WSHttpBinding(); Srv_Login_EndPoint = new EndpointAddress("http://localhost:2687/Srv_Login.svc"); Srv_LoginChannelFactory = new ChannelFactory<Srv_Login.Srv_ILogin>(ws, Srv_Login_EndPoint); } And I'm using service this way: private void btnEnter_Click(object sender, EventArgs e) { try { LoginService = Srv_LoginChannelFactory.CreateChannel(); Srv_Login.LoginResult res = new Srv_Login.LoginResult(); res = LoginService.IsAuthenticated(txtUserName.Text.Trim(), txtPassword.Text.Trim()); if (res.Status == true) { int Id = int.Parse(res.Result.ToString()); } else { lblMessage.Text = "Not Enter"; } } catch (Exception ex) { MessageBox.Show(ex.Message); } finally { Srv_LoginChannelFactory.Close(); } } When the user enters a valid username and password, everything is fine. When the user enters a wrong username and password, the first try correctly displays a "Not Enter" message, but on the second try, the user sees this message: {System.ObjectDisposedException: Cannot access a disposed object.

• Can a web app in xul:iframe access functions from its parent XUL file?

  - by oskar

  I want to deploy a web app as a self-contained program using XULRunner. I'm simply loading it in a xul:iframe tag within the main XUL file. It works, but I want the web app to have access to XUL components, specifically nsiFilePicker. My tentative solution is to run the xul:iframe with escalated privileges (by omitting the "type" attribute), wait for the xul:iframe to load, then define a javascript function that the web app will then call. <window id="main" width="800" height="600" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <iframe id="contentview" src="web/index.html" flex="1"/> <script> //listen for XUL window to load window.addEventListener("load",Listen,false); function Listen() { var frame = document.getElementById("contentview"); frame.addEventListener("DOMContentLoaded", DomLoadedEventHandler, true); } //listen for iframe to load function DomLoadedEventHandler() { //set function in iframe called testMe() var frame = document.getElementById("contentview"); frame.contentWindow.testMe = function () { alert("This is a test"); }; } </script> </window> ...and then in the index.html file of the web app... <script> testMe(); </script> This doesn't seem to work. Does anyone have any suggestions?

• How to access C arrays from assembler for Windows x64?

  - by 0xdword32

  I've written an assembler function to speed up a few things for image processing (images are created with CreateDIBSection). For Win32 the assembler code works without problems, but for Win64 I get a crash as soon as I try to access my array data. I put the relevant info in a struct and my assembler function gets a pointer to this struct. The struct pointer is put into ebx/rbx and with indexing I read the data from the struct. Any idea what I am doing wrong? I use nasm together with Visual Studio 2008 and for Win64 I set "default rel". C++ code: struct myData { tUInt32 ulParam1; void* pData; }; CallMyAssemblerFunction(&myData); Assembler Code: Win32: ... push ebp; mov ebp,esp mov ebx, [ebp + 8]; pointer to our struct mov eax, [ebx]; ulParam1 mov esi, [ebx + 4]; pData, 4 byte pointer movd xmm0, [esi]; ... Win64: ... mov rbx, rcx; pointer to our struct mov eax, [rbx]; ulParam1 mov rsi, [rbx + 4]; pData, 8 byte pointer movd xmm0, [rsi]; CRASH! ...

• Axis webservice calls fail sometimes, access.log shows content!

  - by epischel

  Hi, our app is a webservice client (axis 1) to a third party webservice (also axis 1). We use it for some years now. Since a few weeks, we (as a client) get sometimes HTTP status 400 (bad request) or read timeouts when calling the webservice. Strangely, the access.log of the service shows part of the request or the response instead of the URL. It looks like this (looks like the end of the request string) x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 16127 0 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 22511 1 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "il=\"true\"/><nsl:text xsi:type=\"xsd:string\" xsi:nil=\"true\"/></SOAPSomeOperation></soapenv:Body></soapenv:Envelope> Axis/1.4" 400 299 0 or (some string out of the what looks like the request) x.x.x.x -> y.y.y.y:8080 - - [timestamp] ":string\">some text</sometag><othertag>moretext" 400 299 0 or in some other cases it looks like two requests thrown together (... means xml string left out): x.x.x.x -> y.y.y.y:8080 - - [timestamp] "...</someop></soapenv:Body></soapenv:Envelope>:xsd=\"http://www.w3.org/2001/XMLSchema\"...</soapenv:Body></soapenv:Envelope>" 400 299 0 Application log does not give any hints. Frequency of such call is 1% of all calls to that service. The only discriminator I know of so far is that it happens since operations informed us that the service url changed because of "server migration". Has anyone experienced such phenomenon yet? Has somebody got an idea whats wrong and how to fix? Thanks,

• How to access and run field events from extension js?

  - by Dan Roberts

  I have an extension that helps in submitting forms automatically for a process at work. We are running into a problem with dual select boxes where one option is selected and then that selection changes another field's options. Since setting an option selected property to true doesn't trigger the field's onchange event I am trying to do so through code. The problem I've run into is that if I try to access or run functions on the field object from the extension, I get the error Error: uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://webformsidebar/content/webformsidebar.js :: WebFormSidebar_FillProcess :: line 499" data: no] the line causing the error is... if (typeof thisField.onchange === 'function') The line right before it works just fine... thisField.options[t].selected=true; ...so I'm not sure why this is resulting in such an error. What surprises me most I guess is that checking for the existence of the function leads to an error. It feels like the problem is related to the code running in the context of the extension instead of the browser window document. If so, is there any way to call a function in the browser window context instead? Do I need to actually inject code into the page somehow? Any other ideas? Thanks

• How can I access mainframe data with .Net applications and SQL Queries?

  - by orandov

  We have a large amount of data stored on an IBM mainframe using VSAM files. A lot of this data is dropped on the network every night in the form of text files to be processed and dumped into FoxPro and SQL Server databases. There are also many text files produced nightly by custom applications that get uploaded to the mainframe to keep everything in sync. Keeping the everything in sync is very tricky, to say the least. We are not getting rid of the mainframe any time soon and we would like to replace all the nightly batch processing with real time access to the mainframe data. We would like to be able to: Read data directly from the mainframe and produce reports based on it. Possibly using SQL queries. Read and Write data from custom .Net applications. We are not looking for a new platform to interface with the mainframe like Information Builders offers. We don't want to build application modules or reports with new "Business Intelligence" tools. We already know how to generate reports and write custom applications using SQL,.Net, Visual Studio, etc. All we are looking for is some sort of adapter to connect to our mainframe data. Any ideas are appreciated.

• How do I access the CodeDomProvider from a class inheriting from Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite?

  - by Charlie

  Does anyone know how to get a CodeDomProvider in the new Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite from the Visual Studio 2010 SDK? I used to get access to it just by in mere inheritance of the class Microsoft.CustomTool.BaseCodeGeneratorWithSite, but now with this new class it is not there. I see a GlobalServiceProvider and a SiteServiceProvider but I can't find any example on how to use them. Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite: http://msdn.microsoft.com/en-us/library/bb932625.aspx I was to do this: public class Generator : Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite { public override string GetDefaultExtension() { // GetDefaultExtension IS ALSO NOT ACCESSIBLE... return this.InputFilePath.Substring(this.InputFilePath.LastIndexOf(".")) + ".designer" + base.GetDefaultExtension(); } // This method is being called every time the attached xml is saved. protected override byte[] GenerateCode(string inputFileName, string inputFileContent) { try { // Try to generate the wrapper file. return GenerateSourceCode(inputFileName); } catch (Exception ex) { // In case of a faliure - print the exception // as a comment in the source code. return GenerateExceptionCode(ex); } } public byte[] GenerateSourceCode(string inputFileName) { Dictionary<string, CodeCompileUnit> oCodeUnits; // THIS IS WHERE CodeProvider IS NOT ACCESSIBLE CodeDomProvider oCodeDomProvider = this.CodeProvider; string[] aCode = new MyCustomAPI.GenerateCode(inputFileName, ref oCodeDomProvider); return Encoding.ASCII.GetBytes(String.Join(@" ", aCode)); } private byte[] GenerateExceptionCode(Exception ex) { CodeCompileUnit oCode = new CodeCompileUnit(); CodeNamespace oNamespace = new CodeNamespace("System"); oNamespace.Comments.Add(new CodeCommentStatement(MyCustomAPI.Print(ex))); oCode.Namespaces.Add(oNamespace); string sCode = null; using (StringWriter oSW = new StringWriter()) { using (IndentedTextWriter oITW = new IndentedTextWriter(oSW)) { this.CodeProvider.GenerateCodeFromCompileUnit(oCode, oITW, null); sCode = oSW.ToString(); } } return Encoding.ASCII.GetBytes(sCode ); } } Thanks for your help!

• php simplexmlelement - I can access most properties (except the one with a dash?)

  - by Matthew Steiner

  So I run some code like this: $quote = simplexml_load_string($xml); $quote = $quote->Stock; echo 'Name: '; echo $quote->Name; echo '<br>'; echo 'Sybmol: '; echo $quote->Symbol; echo '<br>'; echo 'Last Price: '; echo $quote->Last; echo '<br>'; echo 'Earnings To Price Ratio: '; echo $quote->P-E; echo '<br>'; I know that the second to last line ($quote-P-E) is incorrect - I don't think you can use dashes like that. But for some reason I can't figure out how to access that property. The weird thing is that's how it's written if I var_dump($quote) (It's towards the end): object(SimpleXMLElement)#17 (16) { ["Symbol"]=> string(4) "AAPL" ["Last"]=> string(6) "271.87" ["Date"]=> string(9) "6/17/2010" ["Time"]=> string(6) "3:59pm" ["Change"]=> string(5) "+4.62" ["Open"]=> string(6) "270.72" ["High"]=> string(6) "272.90" ["Low"]=> string(6) "269.50" ["Volume"]=> string(8) "31195032" ["MktCap"]=> string(6) "247.4B" ["PreviousClose"]=> string(6) "267.25" ["PercentageChange"]=> string(6) "+1.73%" ["AnnRange"]=> string(15) "132.88 - 272.90" ["Earns"]=> string(6) "11.796" ["P-E"]=> string(5) "22.66" ["Name"]=> string(10) "Apple Inc." } How should I be accessing this attribute/property?

• DD_belatedPNG.js - how to access the vml object? this is for a PNG image-swap.

  - by akc

  I am trying to use Drew Dillard's awesome DD_belatedPNG fix + jQuery to achieve a run-of-the-mill image-swap on hover -- but with PNGs, and to work on IE6. Example: <a id="thelink" href="blah.html"><img src="f-u-ie6.png" /></a> Since DD's script sets the visibility of the original image to "hidden", you can't effectively hover over it. A lot of people, I have noticed, are thwarted by this limitation. Enough so that Drew mentioned he would try to get a work-around into the next version of his PNG fix. Well, in the meantime, I thought I could get around this by handling the hover event on the image's parent instead. So onmouseover, I would hide the VML object created by DD_belatedPNG while setting a background image on "thelink", and onmouseout, show the VML object again and set the background image to nothing. The following code was just to see if I could access the VML object, but it does not work on the VML. It hides all manner of other children, but not the VML. Any ideas? $(document).ready(function(){ $("thelink").hover(function() { $(this).children().attr({ style: "visibility:hidden" }); }, function() { $(this).children().attr({ style: "visibility:visible" }); }); }); Alternatively, can anyone suggest a great PNG image-swap method? I know that you can swap a background image of a link. But you still need to have something inside the A tag. That's not my case. Also, you could put a transparent GIF in the A tag and have the background image swapped to achieve the effect, but I really don't want to do that. Thanks for your insights!

• Why compiling in Flash IDE I cannot access stage in a Sprite constructor before addChild while if I

  - by yuri

  I've created this simple class (omissing package directive and imports) public class Viewer extends Sprite { public function Viewer():void { trace(stage); } } then in Flash IDE I import in first frame this AS: import Viewer var viewer = new Viewer(); stage.addChild(viewer); trace(viewer.stage); and this works as I expected: the first trace called in constructor say stage is "null" because I haven't yet add viewer to a DisplayObjectContainer. The second one output the stage object. So I created a project using AXDT eclipse plugin, I've recreated and compiled only the first class (trashed the AS init script used in Flash IDE because is not needed) and on the first trace ... wow ... the stage is filled with the stage Object. I seems to me that the compiler used by AXDT (Flex4 SDK open source) add the class... before construct it (!?).. to a DisplayObjectContainer already attached to a Stage. I want to understand how can reproduce this behaviour using compiler in Flash IDE so I can directrly access Stage in construction.

• how to get access to private members of nested class?

  - by macias

  Background: I have enclosed (parent) class E with nested class N with several instances of N in E. In the enclosed (parent) class I am doing some calculations and I am setting the values for each instance of nested class. Something like this: n1.field1 = ...; n1.field2 = ...; n1.field3 = ...; n2.field1 = ...; ... It is one big eval method (in parent class). My intention is -- since all calculations are in parent class (they cannot be done per nested instance because it would make code more complicated) -- make the setters only available to parent class and getters public. And now there is a problem: when I make the setters private, parent class cannot acces them when I make them public, everybody can change the values and C# does not have friend concept I cannot pass values in constructor because lazy evaluation mechanism is used (so the instances have to be created when referencing them -- I create all objects and the calculation is triggered on demand) I am stuck -- how to do this (limit access up to parent class, no more, no less)? I suspect I'll get answer-question first -- "but why you don't split the evaluation per each field" -- so I answer this by example: how do you calculate min and max value of a collection? In a fast way? The answer is -- in one pass. This is why I have one eval function which does calculations and sets all fields at once.

• How to manage data access / preloading efficiently using web services in C# ?

  - by Amadeus45

  Hello all, Ok, this is very "generic" question. We currently have a SQL Server database for which we need to develop an application in ASP.NET with will contain all the business logic in C# Web Services. The thing is that, architecturally speaking, I'm not sure how to design the web service and the data management. There are many things to consider : We need have very rapid access to data. Right now, we have over a million "sales" and "purchases" record from which we need to often calculate and load the current stock for a given day according to a serie of parameter. I'm not sure how we should preload the data and keep the data in the Web Service. Doing a stock calculation within a SQL query will be very lengthy. They currently have a stock calculation application that preloads all sales and purchases for the day and afterwards calculate the stock on the code-side. We want to develop powerful reporting tools. We want to implement a "pivot table" but not sure how to implement it and have good performances. For the reasons above, I'm not sure how to design the data model. Anybody can give me any guidelines on how to start, or from their personnal experiences (what have you done in the past ?) I'm not sure if it's possible to make a bounty even though the question is new (I'd put 300 rep on it, since I really need something). If you know how, let me know. Thanks

• Should my validator have access to my entire model?

  - by wb

  As the title states I'm wondering if it's a good idea for my validation class to have access to all properties from my model. Ideally, I would like to do that because some fields require 10+ other fields to verify whether it is valid or not. I could but would rather not have functions with 10+ parameters. Or would that make the model and validator too coupled with one another? Here is a little example of what I mean. This code however does not work because it give an infinite loop! Class User Private m_UserID Private m_Validator Public Sub Class_Initialize() End Sub Public Property Let Validator(value) Set m_Validator = value m_Validator.Initialize(Me) End Property Public Property Get Validator() Validator = m_Validator End Property Public Property Let UserID(value) m_UserID = value End property Public Property Get UserID() UserID = m_Validator.IsUserIDValid() End property End Class Class Validator Private m_User Public Sub Class_Initialize() End Sub Public Sub Initialize(value) Set m_User = value End Sub Public Function IsUserIDValid() IsUserIDValid = m_User.UserID > 13 End Function End Class Dim mike : Set mike = New User mike.UserID = 123456 mike.Validator = New Validator Response.Write mike.UserID If I'm right and it is a good idea, how can I go a head and fix the infinite loop with the get property UserID? Thank you.
