  • vb.net Object Initialiser List(Of T)

    - by Tim B James
    I have been looking at some C# code: List<Employee> Employees = new List<Employee>{ new Employee{firstname="Aamir",lastname="Hasan",age=20}, new Employee{firstname="awais",lastname="Hasan",age=50}, new Employee{firstname="Bill",lastname="Hasan",age=70}, new Employee{firstname="sobia",lastname="khan",age=80}, }; Now when I convert this to vb.net Dim Employees as List(Of Employee) = New List(Of Employee)() With { New Employee() With { _ .firstname = "Aamir", _ .lastname = "Hasan", _ .age = 20 _ }, _ New Employee() With { _ .firstname = "awais", _ .lastname = "Hasan", _ .age = 50 _ }, _ New Employee() With { _ .firstname = "Bill", _ .lastname = "Hasan", _ .age = 70 _ }, _ New Employee() With { _ .firstname = "sobia", _ .lastname = "khan", _ .age = 80 _ } _ } I get the error "Name of field or property being initialized in an object initializer must start with'.'." Now I can get an array of employee using the code: Dim Employees = { New Employee() With { _ .FirstName = "Aamir", _ .LastName = "Hasan", _ .Age = 20}, _ New Employee() With { _ .FirstName = "Awais", _ .LastName = "Hasan", _ .Age = 50}, _ New Employee() With { _ .FirstName = "Bill", _ .LastName = "Hasan", _ .Age = 70 _ } _ } But I would like a List(Of Employee) as it is bugging me as to why this doesnt work in vb.net?

  • How to get nearby POIs

    - by balexandre
    I have a database with Points of Interest that all have an address. I want to know what is the method/name/call to get all nearby POIs from a given position. I understand that I need to convert all my addresses to LAT / LON coordinates at least, but my question is: for a given LAT / LONG how do I get from the database/array what POIs are nearby by distance, for example: You are here 0,0 nearest POIs in a 2km radius are: POI A (at 1.1 Km) POI C (at 1.3 Km) POI F (at 1.9 Km) I have no idea what should I look into to get what I want :-( Any help is greatly appreciated. Thank you

  • Globalize2 and migrations

    - by diegogs
    Hi, I have used globalize2 to add i18n to an old site. There is already a lot of content in spanish, however it isn't stored in globalize2 tables. Is there a way to convert this content to globalize2 with a migration in rails? The problem is I can't access the stored content: >> Panel.first => #<Panel id: 1, name: "RT", description: "asd", proje.... >> Panel.first.name => nil >> I18n.locale = nil => nil >> Panel.first.name => nil Any ideas?

  • Executing a DTS package from Sql Server 2005

    - by Doerr
    I am trying to run several DTS packages from a sql 2000 box. The DTS calls will originate from .net 2.0 - 3.5 code. I have been unable to find a good way to programmatically accomplish this. What I have read is running a sql job from a stored procedure that calls the DTS package. Does anyone has any experience with this or know of a good way to call the DTS? Note: For the forseeable future these packages will remain DTS. Eventually we will convert them to SSIS. Any insight or experience would be very helpful.

  • quantity of measurable units design pattern

    - by Berryl
    Hello I am thinking through a nice pattern to be useful across domains of measurable units (ie, Length, Time) and came up with the following use case and initial classes, and of course, questions! 1) Does a Composite pattern help or complicate? 2) Should the Convert method(s) in the ComposityNode be a separate converter class? All comments appreciated. Cheers, Berryl Example Use Case: var inch = new ConvertableUnit("inch", 1) var foot = new ConvertableUnit("foot", 12) var imperialUnits = new CompositeConvertableUnit("imperial units", .024) imperialUnits.AddChild(inch) imperialUnits.AddChild(foot) var meter = new ConvertableUnit("meter", 1) var millimeter = new ConvertableUnit("millimeter ", .001) var imperialUnits = new CompositeConvertableUnit("metric units", 1) imperialUnits.AddChild(meter) imperialUnits.AddChild(millimeter) var oneInch = new Quantity(1, inch); var oneFoot = new Quantity(1, foot); oneFoot.ToBase() // "12 inches" var oneMeter = new Quantity(1, meter); oneInch.ToBase() // .024 meters Possible Solution ConvertableUnit : Node double Rate string Name Quantity ConvertableUnit Unit double Amount CompositeConvertableUnit : Node ISet<ConvertableUnit> _children ConvertableUnit BaseUnit {get{ return _children.Where(c=>c.Rate == 1).First() } } Quantity ConvertTo(Quantity from, Quantity to) Quantity ToBase(Quantity from);

  • using bash: write bit representation of integer to file

    - by theseion
    Hullo First, I want to use bash for this and the script should run on as many systems as possible (I don't know if the target system will have python or whatever installed). Here's the problem: I have a file with binary data and I need to replace a few bytes in a certain position. I've come up with the following to direct bash to the offset and show me that it found the place I want: dd bs=1 if=file iseek=24 conv=block cbs=2 | hexdump Now, to use "file" as the output: echo anInteger | dd bs=1 of=hextest.txt oseek=24 conv=block cbs=2 This seems to work just fine, I can review the changes made in a hex editor. Problem is, "anInteger" will be written as the ASCII representation of that integer (which makes sense) but I need to write the binary representation. How do I tell the command to convert the input to binary (possibly from a hex)?

  • XML RSS to HTML parser doesn't work

    - by mstr
    I'm using MCX (I don't even know if someone here is familiar with it, pretty unkown derivate of COBOL and Fortran, look it up in google when you don't believe me) Note: I'm using MCX on the MCX-WebServices server as it does neither support apache or ISS, mabye that is one problem. The thing is that I want to use the XML library to read in an XML file and convert it into an output format readable by the user. The XML lib already has all the functions I need for that, yet my program fails. #!usr/bin/mcx $PGRM.ID: index.mcx $PGRM.AT: /mstr SHOWERROR: WRITE XML.LastError --> OUTPUT DO_FLUSH xcit end\ MAIN: IMPORT Extras.XML USE Extras $XML_RSS_FILE: XML.ReadIn "rss.xml" ! $XML_RSS_FILE --> GOTO SHOWERROR $XML_RSS: XML.FormatRSS1 <-- $XML_RSS_FILE ! $XML_RSS --> GOTO SHOWERROR WRITE $XML_RSS --> OUTPUT DO_FLUSH FLUSH xcit end\ Program output: Nothing The rss.xml file 100% exists and is readable Thanks in advance

  • setlocale/strftime issue

    - by Manos Dilaverakis
    I am using the following to output the full name of a month in Greek. setlocale(LC_TIME, 'el_GR'); strftime("%B"); This works, except the output string is ISO-8859-7 (greek code page), which is a problem since I need a UTF-8 string. I could put this through iconv to convert it, but I was wondering if there was a way to do that without resorting to an extra function. Could you somehow tell strftime to output a UTF-8 string in this case?

  • How does one bind to a List<DataRow> collection in WPF XAML?

    - by Elan
    Using a DataTable or DataView, one can specify the binding in XAML for example as follows: <Image Source="{Binding Thumbnail}" /> In my case I have created a List collection of DataRow objects and the above is not working. This is my data source: List<DataRow> I could of course convert the List< to a DataTable, but I am curious if there was a way to specify the binding in XAML to access the "Thumbnail" column within the DataRow that is stored in a List< collection.

  • How to debug a GWT application running on OSGi?

    - by Jaime Soriano
    I'm developing a web UI using GWT. While working only with the widgets I could debug from Eclipse using the Firefox extension, but now that I'm integrating the UI with other OSGi bundles I cannot use this solution. For deploying the GWT application I create the .war and convert it to an OSGi bundle using BND. Then I launch the OSGi container with all the bundles using Pax Runner and Pax Web and the application works correctly, but when something fails in the generated javascript code I don't have any decent output error or debugging facility. Is there any way to launch the GWT application in "debug mode" from OSGi? Any other idea that could help in this scenario?

  • Text Editor For Flash?

    - by JasonS
    Hi, I work for a company which produces flash websites. The CMS is built in PHP. The client can update the text on the CMS site. Currently it uses a really old, bad, flash text-editor. It needs to be upgraded to something much much better. I need a text editor that will produce 'flash-html' as well as 'valid-html'. Or even something that marks up the text in the way that would allow me to do this. I tried using TinyMCE and ran into problems trying to convert the HTML. Has anyone tried doing this? Can anyone recommend anything or give any tips on how I can do this?

  • How to reuse a dropdownlist each row of a table instead of rebuilding it.

    - by Praesagus
    I have a table the uses the same dropdown list in each row. I thought that I could just create one dropdown list and then reuse it in each new row, but the table only ends up with one row unless I create "new" dropdownlist. Am I approaching this all wrong? Thanks private void UserRoles() { Table table = MakeTable(); Ewo.sqlDataStore.Administrator sql = new Ewo.sqlDataStore.Administrator(); DataSet dataset =sql.SiteUserRoleList(); DropDownList sel = RoleList(dataset.Tables[0]); if(tools.validDataSet(dataset)) { if (dataset.Tables.Count > 1)//existing roles are #2, show the roles the user is part of { foreach (DataRow dRow in dataset.Tables[1].Rows) { table.Rows.Add(CreateRoleRow(Convert.ToString(dRow["SitePageGroupName"]), sel));//add a row with data } } table.Rows.Add(CreateRoleRow(sel));//add a blank row on the bottom } AdminSiteUerRoles.Controls.Add(table);//add it all to the page }

  • Compressing three individual jpeg pics containing temporal redundancy?

    - by michael
    I am interfacing and embedded device with a camera module that returns a single jpeg compressed frame each time I trigger it. I would like to take three successive shots (approx 1 frame per 1/4 second) and further compress the images into a single file. The assumption here is that there is a lot of temporal redundancy, therefore lots of room for more compression across the three frames (compared to sending three separate jpeg images). I will be implementing the solution on an embedded device in C without any libraries and no OS. The camera will be taking pics in an area with very little movement (no visitors or screens in the background, maybe a tree with swaying branches), so I think my assumption about redundancy is pretty solid. When the file is finally viewed on a pc/mac, I don't mind having to write something to extract the three frames (so it can be a nonstandard cluge) So I guess the actual question is: What is the best way to compress these three images together given the fact that they are already in JPEG format (it is a possibly to convert back to a raw image, but if i dont have too...)

  • user model password field default password field in django

    - by imran-glt
    Hi, I've created a custom user model in my application. This user model is working fine, but there are a couple of problems I have with it. 1) The change password link in the my register.html page doesn't work? 2) The default password box on the add/edit page for a user is a little unfriendly. Ideally, what I'd like is the two password fields from the change password form on the add/edit user form in the admin, which will automatically turn convert the entered password into a valid encrypted password in Django. This would make the admin system MUCH friendlier and much more suited to my needs, as a fair number of user accounts will be created and maintained manually in this app, and the person responsible for doing so will likely be scared off at the sight of that admin field, or just type a clear text password and wonder why it doesn't work. Is this possible / How do I do this?

  • Capturing a NSParseErrorException

    - by Martin
    Could someone tell me how I can capture a NSParseErrorException? The Situation: my app downloads a small .plist file. I convert this into dictionary using the string method -propertylist. This normally works fine. I check for a connection before going to retrieve the file, so it works fine if I've got a connection to the internet, and works fine when I don't. However, I discovered a use case that crashes. If I'm at location that requires authetication before connecting to the internet (at Starbucks, say) what's being returned by the app isn't a plist and the attempt to parse it causes the application to crash. So is there a way to transform my code so that the NSParseErrorException is caught and rather than crashing the program I can just skip over this piece of code? NSDictionary *temp = [myDownloadString propertyList]; I tried doing this if ([myDownloadString propertyList]==NSParseErrorException){ //do something } but that didn't work.

  • What is the best way to generate a sitemap?

    - by Zakaria
    Hi everybody, I need to build a sitemap for my website. The url will be "www.example.com/mysitemap.html". I know that there are some tools that generate automatically an XML file that contains the reachable URLs and also improve the SEO. So my questions are: How can I build this HTML page going from the generated XML? Or am I wrong and this kind of HTML page is built manually? If not, how do we integrate the XML and convert it to the website? Thank you very much. Regards.
