• What is the worst programming language you ever worked with? [closed]

  - by Ludwig Weinzierl

  If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

• Choosing an installer product that is free and will download/install the .NET Framework

  - by Coder7862396

  I'm currently using the Visual Studio Installer (Setup Project) in Visual Studio 2010 as the installer for MyProgram. It has some quirky bugs and is not very customizable so I would like to switch to another installer product. Here are my requirements: Must be free (and licensed for commercial use) Must install the Windows Installer 3.1 and .NET Framework 4.0 if the client doesn't have them The installer will download them if they are not available The code for detecting the .NET Framework and downloading it must be written by Microsoft (I do not want to have to update hard-coded URLs and registry keys in the future). I know that the Windows SDK includes a setup bootstrap that does this (C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper) In the future, when .NET Framework 5 is released and MyProgram uses it, no installer code will need to be changed, the updated installer product should see that MyProgram now uses the .NET Framework version 5 and will install that Here are my current choices: Visual Studio Installer: Automatically detects/downloads/installs Windows Installer and .NET Framework using a bootstrapper Setup.exe (Good!) Limited/buggy functionality (Uninstall shortcuts in the Start Menu cause empty folders to be left behind during uninstall, asking the user if they want a desktop shortcut requires a lot of work, etc.) NSIS: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLS, etc. Inno Setup: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLs, etc. WiX: Steep learning curve... not sure if I want to spend weeks learning it only to find out that it has the same uninstall problem as the Visual Studio Installer (because they both use MSI files) InstallShield LE 2010: Downloading it requires me to setup a fake email account to register just to download it. Then once it is installed it has to contact the company's servers and transmit some private information to them before I'm even allowed to try the free version. This is the most insidious form of DRM that there is and I will not accept it.

• does anyone know of good delphi docking components?

  - by X-Ray

  we'd like to add movable panels to an application. presently we've used DevExpress docking library but have found them to be disappointingly quirky & difficult to work with. it also has some limitations that aren't so great. auto-hide, pinning, and moving of pages by drag-and-drop are all features we'd like to use. the built-in delphi docking doesn't seem to be full-featured enough to do the things we need (also see sample below). perhaps i should dig deeper into delphi's docking abilities...my initial impression is that they seem very toolbar-oriented rather than something i can drop a frame into. i'm not experienced at docking topics. my only experience has been with the DevExpress docking library where i needed to programmatically create & dock panels. is it my imagination or are DevExpress's products unduly difficult to use/learn? the DevExpress Ribbon Bar component compared to the d2009 Ribbon Bar was certainly a useful experience. i will migrate to the d2009 Ribbon Bar as soon as convenient to do so. it was refreshingly straight-forward to learn and use. a sharp contrast compared to the DevExpress equivalent. if it takes 4x as longer to make it using the DevExpress equivalent, it's time to change direction. what would you suggest in regard to the docking library? thank you for your suggestions/comments!

• Is there a website to look up common, already written functions?

  - by pinnacler

  I'm sitting here writing a function that I'm positive has been written before, somewhere on earth. It's just too common to have not been attempted, and I'm wondering why I can't just go to a website and search for a function that I can then copy and paste into my project in 2 seconds, instead of wasting my day reinventing the wheel. Sure there are certain libraries you can use, but where do you find these libraries and when they are absent, is there a site like I'm describing? Possibly a wiki of some type that contains free code that anybody can edit and improve? Edit: I can code things fine, I just don't know HOW to do them. So for example, right now, I'm trying to localize a robot/car/point in space. I KNOW there is a way to do it, just based off of range and distance. Triangulation and Trilateration. How to code that is a different story. A site that could have psuedo code, step by step how to do that would be ridiculously helpful. It would also ensure the optimal solution since everybody can edit it. I'm also writing in Matlab, which I hate because it's quirky, adding to my desire for creating a website like I describe.

• MATLAB matrix replacement assignment gives error

  - by Gulcan

  I tried to update some part of a matrix, I got the following error message: ??? Assignment has fewer non-singleton rhs dimensions than non-singleton subscripts My code tries to update some values of a matrix that represent a binary image. My code is as follows: outImage(3:5,2:4,1) = max(imBinary(3:5,2:4,1)); When I delete last parameter (1), this time I get the same error. I guess there is a mismatch between dimensions but I could not get it. outImage is a new object that is created at that time (I tried to create it before, but nothing changed). What may be wrong?

• ExtJS RowEditor on Grid

  - by Ian Warner

  Hi When my users edits the Grid via RowEditor combo entries and checkboxes are annoying 1 Apple 2 Orange 3 Pear For instance with the combo above the user will select Orange then update - the Grid now instead of saying orange will display the number 2 - I would like it to show orange when a successful edit has been made. code for my combo editor : { allowBlank : false, displayField : 'team', editable : false, emptyText : 'Select Team', forceSelection : true, lazyRender : true, mode : 'remote', name : 'team', store : storeTeam, triggerAction : 'all', valueField : 'id', xtype : 'combo' } I think I read that you could send the complete row back to insert or I should listen to the update of the grid and then change the field but I need some guidance on what is best Cheers

• C# Using Reflection to copy base class properties

  - by David Liddle

  I would like to update all properties from MyObject to another using Reflection. The problem I am coming into is that the particular object is inherited from a base class and those base class property values are not updated. The below code copies over top level property values. public void Update(MyObject o) { MyObject copyObject = ... FieldInfo[] myObjectFields = o.GetType().GetFields( BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance); foreach (FieldInfo fi in myObjectFields) { fi.SetValue(copyObject, fi.GetValue(o)); } } I was looking to see if there were any more BindingFlags attributes I could use to help but to no avail.

• FileUpload and UpdatePanel: ScriptManager.RegisterPostBackControl works the second time.

  - by VansFannel

  Hello. I'm developing an ASP.NET application with C# and Visual Studio 2008 SP1. I'm using WebForms. I have an ASPX page with two UpdatePanels, one on the left that holds a TreeView and other on the right where I load dynamically user controls. One user control, that I used on right panel, has a FileUpload control and a button to save that file on server. The ascx code to save control is: <asp:UpdatePanel ID="UpdatePanelBotons" runat="server" RenderMode="Inline" UpdateMode="Conditional"> <ContentTemplate> <asp:Button ID="Save" runat="server" Text="Guardar" onclick="Save_Click" CssClass="button" /> </ContentTemplate> <Triggers> <asp:PostBackTrigger ControlID="Save" /> </Triggers> </asp:UpdatePanel> I make a full postback to upload the file to the server and save it to database. But I always getting False on FileUpload.HasFile. I problem is the right UpdatePanel. I need it to load dynamically the user controls. This panel has three UpdatePanels to load the three user controls that I use. Maybe I can use an Async File Uploader or delete the right Update Panel and do a full postback to load controls dynamically. Any advice? UPDATE: RegisterPostBackControl works... the second time I click on save button. First time FileUpload.HasFile is FALSE, and second time is TRUE. Second Update On first click I also check ScriptManager.IsInAsyncPostBack and is FALSE. I don't understand ANYTHING!! Why? The code to load user control first time, and on each postback is: DynamicControls.CreateDestination ud = this.LoadControl(ucUrl) as DynamicControls.CreateDestination; if (ud != null) { Button save = ud.FindControl("Save") as Button; if (save != null) ScriptManager1.RegisterPostBackControl(save); PanelDestination.Controls.Add(ud); } Thank you.

• FILESTREAM/FILETABLE Clarifications for Implementation

  - by user1209734

  Recently our team was looking at FILESTREAM to expand the capabilities of our proprietary application. The main purpose of this app is managing the various PDFS, Images and documents to all of the parts we manufacture. Our ASP application uses a few third party tools to allow viewing of these files. We currently have 980GB of data on the Fileserver. We have around 200GB of Binary data in SQL Server that we would like to extract since it is not performing well hence FILESTREAM seems to be a good compromise to the two major data storage/access issues. A few things are not exactly clear to us: FILESTREAM Can or Cannot store its data on a drive that is not locally attached. We already have a File Server with a RAID 10 (1.5TB drives). This server stores all of the documents right now, would we have to move these drives to the SQL Server for FILESTREAM? That would be a tough bullet to bite since the server also is doubling as the Application Server (Two VMs on one physical server). FILETABLE stores the common metadata about the files but where is the Full Text part of it stored to allow searching of files like doc/docx? Is this separate? Are you able to freely add criteria to this to search by? If so any links to clarify would be appreciated. Can FILETABLE be referenced in another table with a foreign key? Thank you in advance EDIT: For those having these questions this web video covered everything and more in terms of explaining filestream from 2008 to 2012 and the cavets to consider (I would seriously rep him if I could): http://channel9.msdn.com/Events/TechDays/Techdays-2012-the-Netherlands/2270 In conclusion we will not be using FILESTREAM as it would be way to huge of an upsurge to accommodate for investment. EDIT 2: Update to #1 - After carefully assessing FileTable in addition to FILESTREAM we got a winning combination. We did have to move the files over to the new server (wasn't to painful since they were on the same VM).It honestly took more time to write an extraction tool to dump the binary data within SQL to the File System. Update to #2 - This was seperate but again Bob had an excellent webinar explaining this: http://channel9.msdn.com/Events/TechEd/Europe/2012/DBI411 Update to #3 - Using TFT inheritance we recycled the Docs table we had (minus the huge binary blobs) which required very little changes in our legacy apps. This was a huge upshot for the developer team.

• iPhone App rejected because of Three20 private API undocumented, private UITouch instance variables:

  - by Sijo

  I got a notification mail after submitting to app store.. "During our review of your application we found it is using private APIs, which is in violation of the iPhone Developer Program License Agreement section 3.3.1; "3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs." While your application has not been rejected, it would be appropriate to resolve this issue in your next update. The non-public APIs that are included in your application are the following undocumented, private UITouch instance variables: firstResponder UITouch._locationInWindow UITouch._phase UITouch._previousLocationInWindow UITouch._tapCount UITouch._timestamp UITouch._touchFlags UITouch._view UITouch._window Please resolve this issue in your next update to Application " . My application contains Three20. These variables are used in "UIViewAdditions.m". Is there any way to resolve this issue ? Please help me. Thanks in advance

• JSF 2 equivalent of tomahawk subform

  - by digitaljoel

  I have an existing JSF 1.2 app that was a portlet running on glassfish v2. I'm converting it to a webapp running on glassfish v3. The app uses tomahawk subforms in several areas. Tomahawk has not been update for JSF 2, which is what ships with glassfish v3. We would like to update our app to JSF 2. Is there a JSF 2 equivalent to tomahawk's subform? I know one option would be to change all of the subforms to be ajax enabled and use the execute attribute to specify which controls take part in the form submission, but would like to make this as straight across as I can without modifying existing functionality if I can. So, lacking a tomahawk subform substitute, is there any way to specify partial form submission for non ajax events?

• WPF ComboBox Binding to non string object

  - by Mike L

  I'm using MVVM (MVVM Light Toolkit) and have a property on the view model which exposes a list of objects. The objects contain two properties, both strings, which correlate to an abbreviation and a description. I want the ComboBox to expose the pairing as "abbreviation - description". If I use a data template, it does this easily. I have another property on the view model which represents the object that should display as selected -- the chosen item in the ComboBox. I'm binding the ItemsSource to the list, as it represents the universe of available selections, and am trying to bind the SelectedItem to this object. I'm killing myself trying to figure out why I can't get it to work, and feeling more like a fraud by the hour. In trying to learn why this works, I created the same approach with just a list of strings, and a selected string. This works perfectly. So, it clearly has something to do with the typing... perhaps something in choosing equality? Or perhaps it has to do with the data template? Here is the XAML: <Window x:Class="MvvmLight1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="300" DataContext="{Binding Main, Source={StaticResource Locator}}"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Skins/MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> <DataTemplate x:Key="DataTemplate1"> <StackPanel Orientation="Horizontal"> <TextBlock TextWrapping="Wrap" Text="{Binding CourtCode}"/> <TextBlock TextWrapping="Wrap" Text=" - "/> <TextBlock TextWrapping="Wrap" Text="{Binding CourtDescription}"/> </StackPanel> </DataTemplate> </ResourceDictionary> </Window.Resources> <Grid x:Name="LayoutRoot"> <ComboBox x:Name="cmbAbbrevDescriptions" Height="35" Margin="25,75,25,25" VerticalAlignment="Top" ItemsSource="{Binding Codes}" ItemTemplate="{DynamicResource DataTemplate1}" SelectedItem="{Binding selectedCode}" /> <ComboBox x:Name="cmbStrings" Height="35" Margin="25" VerticalAlignment="Top" ItemsSource="{Binding strs}" SelectedItem="{Binding selectedStr}"/> </Grid> </Window> And, if helpful, here is the ViewModel: using GalaSoft.MvvmLight; using MvvmLight1.Model; using System.Collections.Generic; namespace MvvmLight1.ViewModel { public class MainViewModel : ViewModelBase { public const string CodesPropertyName = "Codes"; private List<Court> _codes = null; public List<Court> Codes { get { return _codes; } set { if (_codes == value) { return; } var oldValue = _codes; _codes = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(CodesPropertyName, oldValue, value, true); } } public const string selectedCodePropertyName = "selectedCode"; private Court _selectedCode = null; public Court selectedCode { get { return _selectedCode; } set { if (_selectedCode == value) { return; } var oldValue = _selectedCode; _selectedCode = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(selectedCodePropertyName, oldValue, value, true); } } public const string strsPropertyName = "strs"; private List<string> _strs = null; public List<string> strs { get { return _strs; } set { if (_strs == value) { return; } var oldValue = _strs; _strs = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(strsPropertyName, oldValue, value, true); } } public const string selectedStrPropertyName = "selectedStr"; private string _selectedStr = ""; public string selectedStr { get { return _selectedStr; } set { if (_selectedStr == value) { return; } var oldValue = _selectedStr; _selectedStr = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(selectedStrPropertyName, oldValue, value, true); } } /// <summary> /// Initializes a new instance of the MainViewModel class. /// </summary> public MainViewModel() { Codes = new List<Court>(); Court code1 = new Court(); code1.CourtCode = "ABC"; code1.CourtDescription = "A Court"; Court code2 = new Court(); code2.CourtCode = "DEF"; code2.CourtDescription = "Second Court"; Codes.Add(code1); Codes.Add(code2); Court code3 = new Court(); code3.CourtCode = "DEF"; code3.CourtDescription = "Second Court"; selectedCode = code3; selectedStr = "Hello"; strs = new List<string>(); strs.Add("Goodbye"); strs.Add("Hello"); strs.Add("Ciao"); } } } And here is the ridiculously trivial class that is being exposed: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace MvvmLight1.Model { public class Court { public string CourtCode { get; set; } public string CourtDescription { get; set; } } } Thanks!

• Why does Java tell me my applet contains both signed and unsigned code?

  - by JohnCooperNZ

  My signed Java applet has been running fine until Java update 19. Now some but not all of our users on Java Update 19 report a java security message stating that our applet contains both signed and unsigned code. The process for creating our applet is as follows: 1: Clean and Build the applet project in Netbeans IDE. 2: Open the Applet jar file in WinRAR and add the required mysql JDBC driver .class files to the jar file. 3: Sign the applet jar file. Can someone please tell me how to determine what code is signed and what code is not signed in our applet? Is there a better way to include the mysql JDBC driver jar file in our applet other than copying the jar file contents into our applet jar file? Thanks

• TryUpdateModel is not working for new Record on ASP.NET MVC Page?

  Hi I have a customer Registartion page using ASP.NET MVC with fields like FirstName, LastName, Address from AddressDetail Table. When i create a new object for CustomerMaster and trying to update the fields using TryUpdateModel, it is not updating. But the TryUpdateModel is working fine on the Edit Profile Page and that particular record is referenced.

• Need Help with Jquery TableSorter Pager plugin.

  Hi I am using the tablesorter plugin: http://tablesorter.com/docs/ with jquery 1.4.2 Now my problem is this. The user can dynamically add rows to the table. But this seems to mess up the paging. Like first it gets added to the first "page" of rows but if you would go to the second page and you go back to the first page. You newly record is gone. I don't know where it goes but it is just gone. I tried to do this $('#pagerid').unbind('click'); $('#tbl tbody ').append(response.HtmlRow); $('#tbl').trigger('update'); So I tried to unbind the pager click method and do a trigger update but that does not seem to work. I then tried to add this line after the above 3 lines. $('#tbl').tablesorterPager({ container: $('#pagerid') }); but it seems to do nothing too. http://tablesorter.com/docs/example-pager.html

• How to handle Append Only text fields in a Sharepoint DataSheet view?

  - by Telos

  We've created a Sharepoint site to track a process. Eventually we're going to make a workflow out of it, but in the meantime there's a list we all have to look at which lists the various dates each piece is supposed to be finished. So basically My group needs to see and update columns X, Y, Z and Comments while ignoring the other 30 billion or so columns. Which is great in datasheet view because we can easily view our columns, and update them right there without drilling into the item and browsing through all the other crap we don't need. The problem is the Comments field, in which we really need to see the last actual comment made. Unfortunately whenever anyone saves the record the field is updated with a blank value (unless they entered a comment) and the last actual comment is lost unless you drill into the item. Is there some way to get the Datasheet view to show all the entries? I should also note that I know very little about Sharepoint 2007... so detailed answers would be nice!

• 'ORA-01031: insufficient privileges' error received when inserting into a View

  - by Patrick K

  Under the user name 'MY_ADMIN', I have successfully created a table called 'NOTIFICATIONS' and a view called 'V_NOTIFICATIONS'. On the 'V_NOTIFICATIONS' view I have successfully created a trigger and a package that takes what the user attempts to insert into the view and inserts it into the table. The 'V_NOTIFICATIONS' trigger and package also perform the update and delete functions on the table when the user attempts to perform the update and delete functions on the view. I have done this with many views in the project I am currently working on, as many views sit over the top of many different tables, however when attempting to insert a record into this view I receive an 'ORA-01031: insufficient privileges' error. I am able to insert directly into the table using the same code that is in the package, but not into the view. Any help on this would be greatly appreciated.

• Ruby/Rails display general screen when modifications being performed on server

  - by john chan

  I have a ruby on rails app running a server and sometimes it needs to be taken down for updates/etc. As of now, one way I see to have a general display screen during update periods (when the app is down) is to substitute the files within /srv/www/ directory to just have it display a general screen everywhere that the user could possibly navigate to. I also thought of having a central controller file that connects all others (essentially a main) but this seems counter intuitive for rails. There are many external links to these different components of the site that the user could navigate to from outside and I need to make sure that they always receive this general update screen when the app is taken down for a little. I was wondering if anyone had any other ideas.... maybe a library or something like that, I can't seem to find anything online. any suggestions would be appreciated. Thanks

• How to change the datasource on a YUI datagrid after creation

  - by Simon

  I am using the Yahoo DataTable for which the API is here. I am having difficulty changing the data once I have rendered the grid once. I am using jQuery to get data via AJAX, or from a client side data island and need to put this back into the grid. There is no setDataSource method in the DataTable API, and changing 'dataSource.liveData' does not update the grid. // does not work dataTable.dataSource.liveData = [ {name:"cat"}, {name:"dog"}, {name:"mouse"}; The example I am basing my code on is the basic LocalDataSource example. How can I update the data source without having to completely recreate the table. I do NOT want to use the YUI datasources that make Async calls. I need to know how I can do this 'manually'.

If I update the page using an AJAX update panel I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd It seems that the chart handler stops after a period of inactivity. Most of the webpages I've looked at for this error are for situations when this error is displayed all the time. In my case it is only displayed after a period of inactivity. Can someone provide a better explanation of what is happening and suggest a solution?
