  • Test for external undefined references in Linux

    - by Charles
    Is there a built in linux utility that I can use to test a newly compiled shared library for external undefined references? Gcc seems to be intelligent enough to check for undefined symbols in my own binary, but if the symbol is a reference to another library gcc does not check at link time. Instead I only get the message when I try to link to my new library from another program. It seems a little silly to get undefined reference messages in a library when I am compiling a different project so I want to know if I can do a check on all references internal and external when I build the library not when I link to it. Example error: make -C UnitTests debug make[1]: Entering directory `~/projects/Foo/UnitTests` g++ [ tons of objects ] -L../libbar/bin -lbar -o UnitTests libbar.so: undefined reference to `DoSomethingFromAnotherLibrary` collect2: ld returned 1 exit status make[1]: *** [~/projects/Foo/UnitTests] Error 1

  • UIActionSheet cancel button strange behaviour

    - by nevan
    I have a UIBarButtonItem opening an action sheet to offer users choices about what to do. Everything works as expected unless I try to click on the "Cancel" button. The target of the button appears to have moved up from where it should be. I can only activate it by clicking somewhere in the middle of the "Cancel" and "Ok" buttons. I've tried at action sheets in other applications and they work fine, so it's not just my big thumb. The action sheet is opening in a UIViewController - (void)showOpenOptions { UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"Open link in external application?", @"Open in external application") delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel") destructiveButtonTitle:NSLocalizedString(@"Open Link", @"Open Link") otherButtonTitles:nil]; [sheet showInView:self.view]; [sheet release]; }

  • Why it's not "if" and not "else"?

    - by Roman
    I have this code: $link = mysql_connect("localhost", "ctmanager", "pswsafgcsadfgG"); if ( ! $link ) die("I cannot connect to MySQL.<br>\n"); else print "Connection is established.<br>\n"; print "a"; if ( mysql_create_db("ct", $link) ) print "AAA"; else print "BBB"; print "2"; die(); And this is the output: Connection is established. a So, I cannot understand how it's possible that neither "AAA" no "BBB" is outputted. Is it because program dies at mysql_create_db?

  • Analysing Indexes - reducing scans.

    - by GrumpyOldDBA
    The whole subject of database/application tuning is sometimes akin to a black art, it's pretty easy to find your worst 20 whatever but actually seeking to reduce operational overhead can be slightly more tricky. If you ever read through my analysing indexes post you'll know I have a number of ways of seeking out ways to tune the database. -- This is a slightly different slant on one of those which produced an interesting side effect. -- We all know that except for very small tables avoiding...(read more)

  • How to build boost::asio example?

    - by Poni
    Hello, I'm trying to build an example of boost::asio http://www.boost.org/doc/libs/1_43_0/doc/html/boost_asio/example/echo/async_tcp_echo_server.cpp but without any luck. System: Windows Vista, Visual C++ 2008 Pro, Boost 1.43. I've added to the project, at VC, the include path and the additional lib path (see note #1), yet the linker gives me this error: 1>LINK : fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_43.lib' What do I do next? In the documentation (the "getting started" part) it says that some boost's components must be built separately. Ok. How do I do this and where do I find them? In the "getting started" page there's the section "6.1 Link From Within the Visual Studio IDE". It just tells me how to link, and not how to build it. Anyone can shed some light? Because I am definitely missing something here. Note #1: There's not "boost_1_43_0/lib" folder but a "libs". The doc needs a refresh.

  • InvalidOperationException sequence contains more than one element even when only one element

    - by user310256
    I have three tables, tblCompany table, tblParts table and a link table between them tblLinkCompanyParts. Since tblLinkCompanyParts is a link table so the columns that it has are LinkCompanyPartID(primary key), CompanyID from tblCompany table and PartID from tblParts as foreign keys. I have tied them up in the dbml file. In code if I write LinkCompanyParts.Parts (where LinkCompanyParts is an object of the tblLinkCompanyParts type) to get to the corresponding Part object I get the "InvalidOperationException: Sequence constains more than one element". I have looked at the data in the database and there is only one Parts record associated with the LinkCompanyPartID. The stack trace reads like at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source) at System.Data.Linq.EntityRef`1.get_Entity() at ... I read about SingleOrDefault vs FirstOrDefault but since the link table should have a one-one mapping therefore I think SingleOrDefault should work and besides "SingleOrDefault" statement is being generated behind the scenes in the designer.cs file at the following line return this._Part.Entity; Any ideas?

  • DTLoggedExec 1.1.2008.4 Released!

    - by Davide Mauri
    Today I've relased the latest version of my DTExec replacement tool, DTLoggedExec. The main changes are the following: Used a new strategy for version numbers. Now it will follow the following pattern Major.Minor.TargetSQLServerVersion.Revision Added support for Auto Configurations Fixed a bug that reported incorrect number of errors and warnings to Log Providers Fixed a buf that prevented correct casting of values when using /Set and /Param options Errors and Warnings are now counted more precisely. Updated database and log import scripts to categorize logs by projects and sections. E.g.: Project: MyBIProject; Sections: Staging, Datawarehouse Removed unused report stored procedures from database Updated Samples: 12 samples are now available to show ALL DTLoggedExec features From this version only SSIS 2008 will be supported http://dtloggedexec.codeplex.com/releases/view/62218  It useful to say something more on a couple of specific points: From this version only SSIS 2008 will be supportedYes, Integration Services 2005 are not supported anymore. The latest version capable of running SSIS 2005 Packages is the 1.0.0.2. Updated database and log import scripts to categorize logs by projects and sectionsWhen you import a log file, you can now assign it to a Project and to a Section of that project. In this way it's easier to gather statistical information for an entire project or a subsection of it. This also allows to store logged data of package belonging to different projects in the same database. For example:  Updated SamplesA complete set of samples that shows how to use all DTLoggedExec features are now shipped with the product. Enjoy! Added support for Auto ConfigurationsThis point will have a post on its own, since it's quite important and is by far the biggest new feature introduced in this release. To explain it in a few words, I can just say that you don't need to waste time with complex DTS configuration files or options, since a package will configure itself automatically. You just need to write a single statement as a parameter for DTLoggedExec. This feature can simplify deployment *a lot* :)   I the next days I'll write the mentioned post on Auto-Configurations and i'll update the documentation available on theDTLoggedExec website:   http://dtloggedexec.davidemauri.it/MainPage.ashx

  • ASP.NET Build Images Links Dynamically

    - by coson
    Good Day, I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code): DynamicString = FunctionThatCreatesDynamicString() ' DynamicString = "http://external_server/path/to/file1.jpg" If ImageExists(DyanmicString) = StatusCode.200 Then ' Embed link in ASP.NET page Else ' Embed not found image in ASP.NET page End If My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML. Any thoughts? TIA, coson

  • Best way to return a user-generated file, AJAX or Forms?

    - by Bill Zimmerman
    Hi, I'm new to web programming, so I need some help. I am writing a custom file-creation app for my site. A user visits the page, clicks on some various options and toggles some checkboxes, and the presses a 'download now' link. I have a PHP backend which will be processing the submission, and generating a PDF file. After the user presses the download link, I want the download to start like it would for any static link. My question is: What is the best way to do this? From my limited understanding, I have a choice between using AJAX or somehow using forms to submit the data. What are the advantages/disadvantages of each? Does anyone have any good links to examples? Thanks

    Hi all Just wondering if this is a good approach, I need to search for items containing all of the specified keywords in a space-delimted string, is this the right approach this? var result = (from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid orderby row.EventName select new {row, time}); // Split the keyword(s) to limit results with all of those words in. foreach(var keyword in request.Title.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)) { var val = keyword; result = result.Where(row=>row.row.EventName.Contains(val)); } var end = result.Select(row=>new EventDetails { Title = row.row.EventName, Description = TrimDescription(row.row.Description), StartDate = row.time.StartDate, EndDate = row.time.EndDate, Url = string.Format(ConfigurationManager.AppSettings["EventUrl"], row.row.guid) }); response.Total = end.Count(); response.Result = end.ToArray(); Is there a slick Linq-way of doing all of this in one query?

  • How to dynamically generate PDF documents

    - by Thomas
    I want to build a web application for generating stylish PDF documents. The layout should be based on a design templates and the data should come dynamically from the database. Ideally I want to design the template in a "publishing like" tool with placeholders and replace these placeholders by the web application with the data from the database. Think of something like an invoice generator, where a customer could choose from different invoice templates and the invoice data itself coming from the DB. Thanks for your ideas!
