  • Why is my mail stuck in the queue with the status "retry" in Exchange 2003?

    - by Mike C
    I have been having a problem recently where some of our mail is not getting to clients. I looked into the Message queue on my SBS2k3 server and noticed that several recipients are showing up in the queue with a state of "Retry". When I highlight the recipient, the additional queue information says "An SMTP protocol error occured". How can I find out more specifically what error occured, and how could I then go about correcting it? Thanks, Mike

  • HP Proliant Servers - WMI query for system health

    - by Mike McClelland
    Hi, I want to query lots of HP servers to determine their overall health. I don't want to use any packages, or even SNMP - I want to query the server health from WMI and understand if a box is Green/Amber/Red - just like the HP Management Home Page. This MUST be possible - but I can't find any documentation... Oh yes, and the servers are running Windows Server 2003/8. Help!! Mike

  • How do I prevent mail from my Exchange server from being blocked?

    - by Mike C
    Recently one of our client machines was infected with a virus and I believe was spamming addresses in the user's contact list. Since then our server has been appearing on blacklists and it has been causing our e-mail to be blocked and returned by many clients. The virus has since been cleared, what can I do to get our server off these blacklists so that we will have more reliable e-mail service? Will I have to change my IP address? Thanks, Mike

  • How to connect lines in Flash CS4 to fill?

    - by Mike
    Hi, I drew a shape with the pen tool in Flash CS4. When I double click on the line it highlights the entire shape, but I can't fill for some reason. If I single click, only part of the line is highlighted (before it changes angle). How can I get this line to connect as a shape to invoke fill on it? Thanks, Mike

  • Table Formatting in Excel 2007: How do I remove it?

    - by Mike
    I've used the new Table Formatting option in Excel 2007. Now I can't remove it. I've dragged the little blue square up to the last cell on the top left, but it just won't go any further. In fact it just won't go at all. Clear all doesn't remove it. What does? I want my table back! Thanks Mike

  • iPhone: how to test that a 3Gs is what it says it is?

    - by Mike
    I'm about to buy a second hand iPhone. It's supposedly a 3Gs; hardly used and de-blocked. Is there any way of checking this through the handset before I give over my money? I recently sold my Nokia W72 and the guy I sold it too put in a code and it showed him my usage details? Any advice given is greatly appreciated. Thanks Mike.

  • Grounded in Dublin

    - by Mike Dietrich
    Friday's hands-on workshop in the Oracle office in Dublin was quite good fun for everybody - except for Mick who has just recognized that his Ryanair flight back to Cork has been canceled (So I hope you've returned home well!) and me as my flights back to Munich via London City had been canceled as well. It's always good to have somebody in the workshop from Air Lingus so I've got hourly information what's going in in the Irish airspace (and now I know that the system dealing with such situations is an well prepared Oracle database which runs just like a switch watch - Thanks again for all your support!!! Was great to talk to you!!!). But to be honest, there are worse places to be grounded for a few days than Dublin. At least it gave me the chance to do something which I never had time enough before when visiting Oracle Ireland: a bit of sightseeing. When I've realized that nothing seems to move over the weekend I started organizing my travel back yesterday. It was no fun at all because there's no single system to book such a travel. Figuring out all possibilities and options going back to Munich was the first challange. Irish Ferries webpage was moaning with all the unexpected load (currently it's fully down). Hotel booking websites showed vacancies in Holyhead but didn't let me book. And calling them just reveiled that there are no rooms left. Haven't stayed overnight in a train station for quite a while ;-) The website of VirginTrains puzzled me with offering a seat at an enormous price for a train ride from Holyhead to London Euston (Thanks, Sir Richard Branson!) just to tell me after I booked a ticket that there are no seats left (but I traveled German railsways a few weeks ago from Düsseldorf to Frankfurt sitting on the floor as well). Eurostar's website let me choose tickets through the tunnel to tell me in the final step that the ticket cannot be confirmed as there are no seats left - but the next check again showed bookable seats - must be a database from some other vendor which has no proper row level locking ... hm ...?! Finally the TGV page for the speed train to Stuttgart and then the ICE to Munich was not allowing searches for quite a while - but ultimately ... after 4.5 hours of searching, waiting, sending credit card information again and again ... So if you have a few spare fingers please keep them crossed :-) And good luck to all my colleagues traveling back from the Exadata training in Berlin. As Mike Appleyard, my colleague from the UK presales team wrote: "Dublin and Berlin aren't too bad a place to get stuck... ;-)"

  • The best Bar on the globe is ... in Seoul/Korea

    - by Mike Dietrich
    As you know already sometimes I write about things which really don't have to do anything with a database upgrade. So if you are looking for tips and tricks and articles about that topic please stop reading now Actually I'm not a lets-go-to-a-bar person. I enjoy good food and a fine dessert wine afterwards. But last week in Seoul/Korea Ryan, our local host, did ask us after a wonderful dinner at a Korean Barbecue place if we'd like to visit a bar. I was really tired as I flew into Seoul overnight from Sunday to Monday arriving Monday early morning, getting shower, breakfast - and then a full day of very good and productive customer meetings. But one thing Ryan mentioned catched my immediate attention: The owner of the bar collects records and has a huge tube amp stereo system - and you can ask him to play your favorite songs. The bar is called "Peter, Paul and Mary" - honestly not my favorite style of music. And I even coulnd't find a webpage or an address - only that little piece of information on Facebook. But after stepping down the stairs to the cellar my eyes almost poped out of my head. This is the audio system: Enourmus huge corner horn loudspeakers from Western Electric. Pretty old I'd suppose but delivering an incredible present dynamics into the room. And plenty of tube equipment from Jadis, NSA Labs and Shindo Laboratories Western Electric 300B Limited amps from Tokyo. And the owner (I was so amazed I had simply forgotten to ask for his name) collects records since 40 years. And we had many wishes that night. Actually when we did enter Peter, Paul and Mary he played an old Helloween song. That must have been destiny. A German entering a bar in Korea and the owner is playing an old song by one of Germany's best heavy metal bands ever. And it went on with the Doors, Rainbow's Stargazer, Scorpions, later Deep Purple's Perfect Strangers, a bit of Santana, Carly Simon, Jimi Hendrix, David Bowie ...Ronnie James Dio's Holy Diver, Gary Moore, Peter Gabriel's San Jacinto ... and many many more great songs ... Of course we were the last guests leaving the place at 2am in the morning - and I've never ever had a better night in a bar before ... I could have stayed days listening to so many records  ... Thanks Ryan, that was a phantastic night! -Mike

  • New Slides - and a discussion about Dictionary Statistics

    - by Mike Dietrich
    First of all we have just upoaded a new version of the Upgrade and Migration Workshop slides with some added information. So please feel free to download them from here.The slides have one new interesting information which lead to a discussion I've had in the past days with a very large customer regarding their upgrades - and internally on the mailing list targeting an EBS database upgrade from Oracle 10.2 to Oracle 11.2. Why are we creating dictionary statistics during upgrade? I'd believe this forced dictionary statistics creation got introduced with the desupport of the Rule Based Optimizer in Oracle 10g. The goal: as RBO is not supported anymore we have to make sure that the data dictionary has fresh and non-stale statistics. Actually that would have led in Oracle 9i to strange behaviour in some databases - so in Oracle 9i this was strongly disrecommended. The upgrade scripts got hardcoded to create these stats. But during tests we had the following findings: It's important to create dictionary statistics the night before the upgrade. Not two weeks before, not 60 minutes before your downtime begins. But very close to the upgrade. From Oracle 10g onwards you'd just say: $ execute DBMS_STATS.GATHER_DICTIONARY_STATS; This is important to make sure you have fresh dictionary statistics during upgrade for performance reasons. Tests have shown that running an upgrade without valid dictionary statistics might slow down the whole upgrade by factors of 2x-3x. And it would be also a great idea post upgrade to create again fresh dictionary statistics when you've did suppress the stats creation during the upgrade process. Suppress? Yes, you could set this underscore parameter in the init.ora: _optim_dict_stats_at_db_cr_upg=FALSE to suppress the forced dictionary statistics collection during an upgrade. We believe strongly that (a) people using the default statistics creation process which will create dictionary statistics by default and (b) create fresh stats before upgrade on the dictionary. Therefore we find it save once you have followed our advice to use the underscore during upgrade. And we've taken out that forced statistics collection during upgrade in the next release of the database. Please note: If you are using the DBUA for the upgrade it will remove underscore parameters for the upgrade run to improve performance - which is generally a good idea. So you'll have to start the DBUA with that call: $ dbua -initParam "_optim_dict_stats_at_cb_cr_upg"=FALSE -Mike

  • .NET Framework generates strange DCOM error

    - by Anders Oestergaard Jensen
    Hello, I am creating a simple application that enables merging of key-value pairs fields in a Word and/or Excel document. Until this day, the application has worked out just fine. I am using the latest version of .NET Framework 4.0 (since it provides a nice wrapper API for Interop). My sample merging method looks like this: public byte[] ProcessWordDocument(string path, List<KeyValuePair<string, string>> kvs) { logger.InfoFormat("ProcessWordDocument: path = {0}", path); var localWordapp = new Word.Application(); localWordapp.Visible = false; Word.Document doc = null; try { doc = localWordapp.Documents.Open(path, ReadOnly: false); logger.Debug("Executing Find->Replace..."); foreach (Word.Range r in doc.StoryRanges) { foreach (KeyValuePair<string, string> kv in kvs) { r.Find.Execute(Replace: Word.WdReplace.wdReplaceAll, FindText: kv.Key, ReplaceWith: kv.Value, Wrap: Word.WdFindWrap.wdFindContinue); } } logger.Debug("Done! Saving document and cleaning up"); doc.Save(); doc.Close(); System.Runtime.InteropServices.Marshal.ReleaseComObject(doc); localWordapp.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(localWordapp); logger.Debug("Done."); return System.IO.File.ReadAllBytes(path); } catch (Exception ex) { // Logging... // doc.Close(); if (doc != null) { doc.Close(); System.Runtime.InteropServices.Marshal.ReleaseComObject(doc); } localWordapp.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(localWordapp); throw; } } The above C# snippet has worked all fine (compiled and deployed unto a Windows Server 2008 x64) with latest updates installed. But now, suddenly, I get the following strange error: System.Runtime.InteropServices.COMException (0x80080005): Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)). at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache) at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean skipCheckThis, Boolean fillCache) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at Meeho.Integration.OfficeHelper.ProcessWordDocument(String path, List`1 kvs) in C:\meeho\src\webservices\Meeho.Integration\OfficeHelper.cs:line 30 at Meeho.IntegrationService.ConvertDocument(Byte[] template, String ext, String[] fields, String[] values) in C:\meeho\src\webservices\MeehoService\IntegrationService.asmx.cs:line 49 -- I googled the COM error, but it returns nothing of particular value.

  • XmlException - inserting attribute gives "unexpected token" exception

    - by Anders Svensson
    Hi, I have an XmlDocument object in C# that I transform, using XslTransform, to html. In the stylesheet I insert an id attribute in a span tag, taking the id from an element in the XmlDocument. Here is the template for the element: <xsl:template match="word"> <span> <xsl:attribute name="id"><xsl:value-of select="@id"></xsl:value-of></xsl:attribute> <xsl:apply-templates/> </span> </xsl:template> But then I want to process the result document as an xhtml document (using the XmlDocument dom). So I'm taking a selected element in the html, creating a range out of it, and try to load the element using XmlLoad(): wordElem.LoadXml(range.htmlText); But this gives me the following exception: "'598' is an unexpected token. The expected token is '"' or '''. Line 1, position 10." And if I move the cursor over the range.htmlText, I see the tags for the element, and the "id" shows without quotes, which confuses me (i.e.SPAN id=598 instead of SPAN id="598"). To confuse the matter further, if I insert a blank space or something like that in the value of the id in the stylesheet, it works fine, i.e.: <span> <xsl:attribute name="id"><xsl:text> </xsl:text> <xsl:value-of select="@id"></xsl:value-of></xsl:attribute> <xsl:apply-templates/> </span> (Notice the whitespace in the xsl:text element). Now if I move the cursor over the range.htmlText, I see an id with quotes as usual in attributes (and as it shows if I open the html file in notepad or something). What is going on here? Why can't I insert an attribute this way and have a result that is acceptable as xhtml for XmlDocument to read? I feel I am missing something fundamental, but all this surprises me, since I do this sort of transformations using xsl:attribute to insert attributes all the time for other types of xsl transformations. Why doesn't XmlDocument accept this value? By the way, it doesn't matter if it is an id attribute. i have tried with the "class" attribute, "style" etc, and also using literal values such as "style" and setting the value to "color:red" and so on. The compiler always complains it is an unvalid token, and does not include quotes for the value unless there is a whitespace or something else in there (linebreaks etc.). I hope I have provided enough information. Any help will be greatly appreciated. Basically, what I want to accomplish is set an id in a span element in html, select a word in a webbrowser control with this document loaded, and get the id attribute out of the selected element. I've accomplished everything, and can actually do what I want, but only if I use regex e.g. to get the attribute value, and I want to be able to use XmlDocument instead to simply get the value out of the attribute directly. I'm sure I'm missing something simple, but if so please tell me. Regards, Anders

  • Replace conditional with polymorphism refactoring or similar?

    - by Anders Svensson
    Hi, I have tried to ask a variant of this question before. I got some helpful answers, but still nothing that felt quite right to me. It seems to me this shouldn't really be that hard a nut to crack, but I'm not able to find an elegant simple solution. (Here's my previous post, but please try to look at the problem stated here as procedural code first so as not to be influenced by the earlier explanation which seemed to lead to very complicated solutions: http://stackoverflow.com/questions/2772858/design-pattern-for-cost-calculator-app ) Basically, the problem is to create a calculator for hours needed for projects that can contain a number of services. In this case "writing" and "analysis". The hours are calculated differently for the different services: writing is calculated by multiplying a "per product" hour rate with the number of products, and the more products are included in the project, the lower the hour rate is, but the total number of hours is accumulated progressively (i.e. for a medium-sized project you take both the small range pricing and then add the medium range pricing up to the number of actual products). Whereas for analysis it's much simpler, it is just a bulk rate for each size range. How would you be able to refactor this into an elegant and preferably simple object-oriented version (please note that I would never write it like this in a purely procedural manner, this is just to show the problem in another way succinctly). I have been thinking in terms of factory, strategy and decorator patterns, but can't get any to work well. (I read Head First Design Patterns a while back, and both the decorator and factory patterns described have some similarities to this problem, but I have trouble seeing them as good solutions as stated there. The decorator example seems very complicated for just adding condiments, but maybe it could work better here, I don't know. And the factory pattern example with the pizza factory...well it just seems to create such a ridiculous explosion of classes, at least in their example. I have found good use for factory patterns before, but I can't see how I could use it here without getting a really complicated set of classes) The main goal would be to only have to change in one place (loose coupling etc) if I were to add a new parameter (say another size, like XSMALL, and/or another service, like "Administration"). Here's the procedural code example: public class Conditional { private int _numberOfManuals; private string _serviceType; private const int SMALL = 2; private const int MEDIUM = 8; public int GetHours() { if (_numberOfManuals <= SMALL) { if (_serviceType == "writing") return 30 * _numberOfManuals; if (_serviceType == "analysis") return 10; } else if (_numberOfManuals <= MEDIUM) { if (_serviceType == "writing") return (SMALL * 30) + (20 * _numberOfManuals - SMALL); if (_serviceType == "analysis") return 20; } else //i.e. LARGE { if (_serviceType == "writing") return (SMALL * 30) + (20 * (MEDIUM - SMALL)) + (10 * _numberOfManuals - MEDIUM); if (_serviceType == "analysis") return 30; } return 0; //Just a default fallback for this contrived example } } All replies are appreciated! I hope someone has a really elegant solution to this problem that I actually thought from the beginning would be really simple... Regards, Anders

  • Owner of uploads directory is `www-data` but this prevents FTP access via PHP scripts

    - by letseatfood
    To allow write access to Apache, I needed to chown www-data:www-data /var/www/mysite/uploads to my site's upload folder. This allows me to delete files from the folder via unlink() in a PHP script. Unfortunately, this prevents another PHP script, which uses FTP functions, from working. I think it is because the FTP user is mike and now that the uploads directory is owned by www-data, mike cannot access it. I added mike to the group www-data, but this does not fix the issue. Can somebody advise me on how to allow PHP FTP functions to work in addition to file deletion using PHP's unlink() function?

  • Design pattern for cost calculator app?

    - by Anders Svensson
    Hi, I have a problem that I’ve tried to get help for before, but I wasn’t able to solve it then, so I’m trying to simplify the problem now to see if I can get some more concrete help with this because it is driving me crazy… Basically, I have a working (more complex) version of this application, which is a project cost calculator. But because I am at the same time trying to learn to design my applications better, I would like some input on how I could improve this design. Basically the main thing I want is input on the conditionals that (here) appear repeated in two places. The suggestions I got before was to use the strategy pattern or factory pattern. I also know about the Martin Fowler book with the suggestion to Refactor conditional with polymorphism. I understand that principle in his simpler example. But how can I do either of these things here (if any would be suitable)? The way I see it, the calculation is dependent on a couple of conditions: 1. What kind of service is it, writing or analysis? 2. Is the project small, medium or large? (Please note that there may be other parameters as well, equally different, such as “are the products new or previously existing?” So such parameters should be possible to add, but I tried to keep the example simple with only two parameters to be able to get concrete help) So refactoring with polymorphism would imply creating a number of subclasses, which I already have for the first condition (type of service), and should I really create more subclasses for the second condition as well (size)? What would that become, AnalysisSmall, AnalysisMedium, AnalysisLarge, WritingSmall, etc…??? No, I know that’s not good, I just don’t see how to work with that pattern anyway else? I see the same problem basically for the suggestions of using the strategy pattern (and the factory pattern as I see it would just be a helper to achieve the polymorphism above). So please, if anyone has concrete suggestions as to how to design these classes the best way I would be really grateful! Please also consider whether I have chosen the objects correctly too, or if they need to be redesigned. (Responses like "you should consider the factory pattern" will obviously not be helpful... I've already been down that road and I'm stumped at precisely how in this case) Regards, Anders The code (very simplified, don’t mind the fact that I’m using strings instead of enums, not using a config file for data etc, that will be done as necessary in the real application once I get the hang of these design problems): public abstract class Service { protected Dictionary<string, int> _hours; protected const int SMALL = 2; protected const int MEDIUM = 8; public int NumberOfProducts { get; set; } public abstract int GetHours(); } public class Writing : Service { public Writing(int numberOfProducts) { NumberOfProducts = numberOfProducts; _hours = new Dictionary<string, int> { { "small", 125 }, { "medium", 100 }, { "large", 60 } }; } public override int GetHours() { if (NumberOfProducts <= SMALL) return _hours["small"] * NumberOfProducts; if (NumberOfProducts <= MEDIUM) return (_hours["small"] * SMALL) + (_hours["medium"] * (NumberOfProducts - SMALL)); return (_hours["small"] * SMALL) + (_hours["medium"] * (MEDIUM - SMALL)) + (_hours["large"] * (NumberOfProducts - MEDIUM)); } } public class Analysis : Service { public Analysis(int numberOfProducts) { NumberOfProducts = numberOfProducts; _hours = new Dictionary<string, int> { { "small", 56 }, { "medium", 104 }, { "large", 200 } }; } public override int GetHours() { if (NumberOfProducts <= SMALL) return _hours["small"]; if (NumberOfProducts <= MEDIUM) return _hours["medium"]; return _hours["large"]; } } public partial class Form1 : Form { public Form1() { InitializeComponent(); List<int> quantities = new List<int>(); for (int i = 0; i < 100; i++) { quantities.Add(i); } comboBoxNumberOfProducts.DataSource = quantities; } private void comboBoxNumberOfProducts_SelectedIndexChanged(object sender, EventArgs e) { Service writing = new Writing((int) comboBoxNumberOfProducts.SelectedItem); Service analysis = new Analysis((int) comboBoxNumberOfProducts.SelectedItem); labelWriterHours.Text = writing.GetHours().ToString(); labelAnalysisHours.Text = analysis.GetHours().ToString(); } }

  • Design advice for avoiding change in several classes

    - by Anders Svensson
    Hi, I'm trying to figure out how to design a small application more elegantly, and make it more resistant to change. Basically it is a sort of project price calculator, and the problem is that there are many parameters that can affect the pricing. I'm trying to avoid cluttering the code with a lot of if-clauses for each parameter, but still I have e.g. if-clauses in two places checking for the value of the size parameter. I have the Head First Design Patterns book, and have tried to find ideas there, but the closest I got was the decorator pattern, which has an example where starbuzz coffee sets prices depending first on condiments added, and then later in an exercise by adding a size parameter (Tall, Grande, Venti). But that didn't seem to help, because adding that parameter still seemed to add if-clause complexity in a lot of places (and this being an exercise they didn't explain that further). What I am trying to avoid is having to change several classes if a parameter were to change or a new parameter added, or at least change in as few places as possible (there's some fancy design principle word for this that I don't rememeber :-)). Here below is the code. Basically it calculates the price for a project that has the tasks "Writing" and "Analysis" with a size parameter and different pricing models. There will be other parameters coming in later too, like "How new is the product?" (New, 1-5 years old, 6-10 years old), etc. Any advice on the best design would be greatly appreciated, whether a "design pattern" or just good object oriented principles that would make it resistant to change (e.g. adding another size, or changing one of the size values, and only have to change in one place rather than in several if-clauses): public class Project { private readonly int _numberOfProducts; protected Size _size; public Task Analysis { get; set; } public Task Writing { get; set; } public Project(int numberOfProducts) { _numberOfProducts = numberOfProducts; _size = GetSize(); Analysis = new AnalysisTask(numberOfProducts, _size); Writing = new WritingTask(numberOfProducts, _size); } private Size GetSize() { if (_numberOfProducts <= 2) return Size.small; if (_numberOfProducts <= 8) return Size.medium; return Size.large; } public double GetPrice() { return Analysis.GetPrice() + Writing.GetPrice(); } } public abstract class Task { protected readonly int _numberOfProducts; protected Size _size; protected double _pricePerHour; protected Dictionary<Size, int> _hours; public abstract int TotalHours { get; } public double Price { get; set; } protected Task(int numberOfProducts, Size size) { _numberOfProducts = numberOfProducts; _size = size; } public double GetPrice() { return _pricePerHour * TotalHours; } } public class AnalysisTask : Task { public AnalysisTask(int numberOfProducts, Size size) : base(numberOfProducts, size) { _pricePerHour = 850; _hours = new Dictionary<Size, int>() { { Size.small, 56 }, { Size.medium, 104 }, { Size.large, 200 } }; } public override int TotalHours { get { return _hours[_size]; } } } public class WritingTask : Task { public WritingTask(int numberOfProducts, Size size) : base(numberOfProducts, size) { _pricePerHour = 650; _hours = new Dictionary<Size, int>() { { Size.small, 125 }, { Size.medium, 100 }, { Size.large, 60 } }; } public override int TotalHours { get { if (_size == Size.small) return _hours[_size] * _numberOfProducts; if (_size == Size.medium) return (_hours[Size.small] * 2) + (_hours[Size.medium] * (_numberOfProducts - 2)); return (_hours[Size.small] * 2) + (_hours[Size.medium] * (8 - 2)) + (_hours[Size.large] * (_numberOfProducts - 8)); } } } public enum Size { small, medium, large } public partial class Form1 : Form { public Form1() { InitializeComponent(); List<int> quantities = new List<int>(); for (int i = 0; i < 100; i++) { quantities.Add(i); } comboBoxNumberOfProducts.DataSource = quantities; } private void comboBoxNumberOfProducts_SelectedIndexChanged(object sender, EventArgs e) { Project project = new Project((int)comboBoxNumberOfProducts.SelectedItem); labelPrice.Text = project.GetPrice().ToString(); labelWriterHours.Text = project.Writing.TotalHours.ToString(); labelAnalysisHours.Text = project.Analysis.TotalHours.ToString(); } } At the end is a simple current calling code in the change event for a combobox that set size... (BTW, I don't like the fact that I have to use several dots to get to the TotalHours at the end here either, as far as I can recall, that violates the "principle of least knowledge" or "the law of demeter", so input on that would be appreciated too, but it's not the main point of the question) Regards, Anders

  • Objective-C SSL Synchronous Connection

    - by Mike
    Hello, I'm a little new to objective-C but have run across a problem that I can't solve, mostly because I'm not sure I am implementing the solution correctly. I am trying to connect using a Synchronous Connection to a https site with a self-signed certificate. I am getting the Error Domain=NSURLErrorDomain Code=-1202 "untrusted server certificate" Error that I have seen some solutions to on this forum. The solution i found was to add: - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; } to the NSURLDelegate to accept all certificates. When I connect to the site using just a: NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://examplesite.com/"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; It works fine and I see the challenge being accepted. However when I try to connect using the synchronous connection I still get the error and I don't see the challenge functions being called when I put in logging. How can I get the synchronous connection to use the challenge methods? Is it something to do with the delegate:self part of the URLConnection? I also have logging for sending/receiving data within the NSURLDelegate that is called by my connection function but not by the synchronous function. What I am using for the synchronous part: NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:@"https://examplesite.com/"]]; [request setHTTPMethod: @"POST"]; [request setHTTPBody: [[NSString stringWithString:@"username=mike"] dataUsingEncoding: NSUTF8StringEncoding]]; dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSLog(@"%@", error); stringReply = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding]; NSLog(@"%@", stringReply); [stringReply release]; NSLog(@"Done"); Like I mentioned I'm a little new to objective C so be kind :) Thanks for any help. Mike
