  • C# define string format of double/floats to be US english by default

    - by neil
    Hi, I have got several thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings, which are combined on the fly, e.g. string SQL = "select * from table where double_value = " + Math.Round(double_value, 2); Don't comment on bad programming style, that doesn't help me in this case :) The cruix: My system uses a German locale, which in turn leads to wrong SQL statements, like this: "select * from table where double_value = 15,5" (Note the comma as decimal separator instead of a point). Question: What is the most "elegant" way to change the locale of the web app in this case) to US or UK in order to prevent being forced to change and inspect every single line of code? .net 3.5 is not an option (would give me the chance to overwrite ToString() in an extension class) Kind regards

  • GWT and a jaxb objects

    - by arinte
    I am trying to use GWT to build objects on the client side that would be sent to a web service elsewhere. These objects are generate through JAX-WS which I am pretty sure uses jaxb to build objects from the xsds that are in the wsdl. Anyhow, GWT was supposed to be able to support this by ignoring annotations or whatever, but it isn't working for me. Here is one of the errors that I am getting: Line 4: The import javax.xml.bind cannot be resolve I am using GWT 2 and the Google plugin for Eclipse.

  • Android: Access child views from a ListView

    - by lacker
    I need to find out the pixel position of one element in a list that's been displayed using a ListView. It seems like I should get one of the TextViews and then use getTop, but I can't figure out how to get a child view of a ListView. Thanks! Update: The children of the ViewGroup do not correspond 1-to-1 with the items in the list, for a ListView. Instead, the ViewGroup's children correspond to only those views that are visible right now. So getChildAt operates on an index that's internal to the ViewGroup and doesn't necessarily have anything to do with the position in the list that the ListView uses. :-/

  • An analog of String.Join(string, string[]) for IEnumerable<T>

    - by abatishchev
    class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

  • Unable to delete file locked by same process -- weird!

    - by user300266
    I have an application written in PHP that uses a COM dll written in C#. The dll creates an image file by combining two other image files. The PHP script then takes over to do the housekeeping tasks of deleting the two source files and renaming the resulting combined file. The problem is the PHP script can't delete one of the source files because it's locked. The weird thing is that the process that has it locked is itself which in this case is the Apache Web Server. I have tried altering the C# dll to dispose of all bitmap and graphics objects prior to exiting, and yet the lock remains. My question is, what can I do to get the dll to let go and release the file locks. This is very frustrating.

  • XNA Class Design with Structs as Properties and issues because they are value types and not referenc

    - by Nate Bross
    I'm wondering how you'd recommend designin a class, given the fact that XNA Framework uses Struct all over the place? For example, a spite class, which may require a Vector2 and a Rectangle (both defined as Struct) to be accessed outside of the class. The issue come in when you try to write code like this: class Item { public Vetor2 Position {get; set;} public Item() { Position = new Vector2(5,5); } } Item i = new Item(); i.Positon.X = 20; // fails with error 'Cannot modify the return value of Item because it is not a variable.' // you must write code like this var pos = i.Position; pos.X++; i.Position = pos; The second option compiles and works, but it is just butt ugly. Is there a better way?

  • Converting Flash frame to JPEG

    - by dhorn
    We are attempting to convert a flash frame into a JPEG without using the Flex SDK or other adobe tools. Right now, we have a flash file that passes binary data over to a .cfm page, which uses the following code to change the headers: <cfset var = GetHttpRequestData()> <cfcontent type="image/jpeg"> <cfheader name="Content-Disposition" value="attachment; filename=#url.name#"> <cfoutput>#var.content#</cfoutput> This code is producing some strange results. Basically, it renders as an image, and I can "right click - Set as desktop background", but I cannot save the image any other way, as it simply saves the contents of the HTML Source. So, questions: 1) Is what I'm trying to do even possible? 2) If so, any suggestions? Thanks guys.

  • How to manipulate the GL.bindframebuffer to target to bind GL_EXT_framebuffer

    - by Alan
    I'm trying to change the framebuffer object from GL_ARB_framebuffer and force it to use GL_EXT_framebuffer since my system is not compatible with the first one. Where in the solution do I need to implement this and how? more information on my problem whenever I create a new Windows OpenGL project from Visual Studio using MonoGame i get the error "cannot find entry point in glbindframebuffer in opengl32.dll" since the framebuffer it uses is GL_ARB_framebuffer which is only supported in Opengl 3 so in a github post i read Gihub post where they suggest this patch that in order to patch you need to force the frame buffers to use GL_EXT_framebuffer but I dont know how to force them to use the EXT instead of the ARB , btw Im using Opengl v2 Mobile intel 4 series card, which is Opengl v2 and ARB needs Opengl v3.

  • Database: relational/not relational/object oriented... What to choose?

    - by Damian
    I'm porting a website that I made for app engine to run on a dedicated server. It is coded in java and I'm looking for a database to replace google datastore. My first thougt was MySql because everybody uses it, but i dont like SQL and I think I would feel more comfortable using OODB or anything else. With google datastore I could modify my models and don't worry about the database definition at all. I know using MySql that isn't possible. And I don't want to miss that. And if I use a OODB, which should I use? What about performance compared to MySql? Well, any idea or tip will really help me since I know nothing about databases.

  • Getting progress status out of a class library method

    - by Richard
    This app that I am doing uses a class library (if I dare call it that) to do the bulk of the work: 2 main methods in there (DoWork and UndoWork) use the other classes to achieve thier goal. Now that that works, I want to get out of the Console test enviroment and do a GUI. How would I get the status of say, the DoWork() method to update a progress bar? Should I multilate the class library (which currently works with the Console and Windows.Forms) to update? The problem with that is that I would surely have to make the class library use Window.Forms which will mess up the console testing apps (And there are lots of them - I tested all the way through, and then all together). Could you suggest some ideas, or places I can read up about ideas (the whole point of writing this this program is to learn, afer all)? Oh, by the way, suggestions like "foresight" or "planning" probably won't help here...(now, anywyay!) - But certainly will in future projects!

  • Why doesn't Microsoft release a 'proper' AJAX grid for ASP.Net

    - by Maxim Gershkovich
    Why doesn't Microsoft release a 'proper' AJAX grid for ASP.Net either as part of Visual Studio or the AJAX control toolkit? Has there been any discussion that anyone is aware of regarding this issue? Also does anyone have any open source suggestions for 'proper' AJAX gridviews? So far I have found one.... http://dotnetslackers.com/projects/AjaxDataControls/Default.aspx PS: By proper I mean a grid that actually uses XML responses rather than the nasty html javascript based injection that is the current nastyness of the gridview (EVEN IN VS 2010).

  • MYSQL: How do I set a date (makedate?) with month, day, and year

    - by chongman
    Hi? I have three columns, y, m, and d (year, month, and day) and want to store this as a date. What function would I use on mySQL to do this? Apparently makedate uses year and day of year (see below), but I have month. I know I can use STR_TO_DATE(str,format), by constructing the string from (y,m,d), but I would guess there is an easier way to do it. REFERENCES MAKEDATE(year,dayofyear) Returns a date, given year and day-of-year values. dayofyear must be greater than 0 or the result is NULL.

  • Is it possible to destroy a CDI scope?

    - by Matt Ball
    I'm working on a Java EE application, primarily JAX-RS with a JSF admin console, that uses CDI/Weld for dependency injection with @ApplicationScoped objects. Minor debugging issues aside, CDI has worked beautifully for this project. Now I need some very coarse-grained control over CDI-injected object lifecycles. I need the ability to: Remove an injected object from the application context, or Destroy/delete/clear/reset/remove the entire application context, or Define my own @ScopeType and implementing Context in which I could provide methods to perform one of the two above tasks. I'm fully aware that this is across, if not against, the grain of CDI and dependency injection in general. I just want to know Is this remotely possible? If yes, what is the easiest/simplest/quickest/foolproofiest way to get the job done?

  • Windows Mobile camera capture issue with DirectShow

    - by user1112111
    I wrote a C# application that uses DirectShow to allow users to take photos with the camera attached to a Windows Mobile 6 phone. The problem I spotted out is that the preview functionality stops working after a period of not using it. How could I determine what's causing this ? Is there a timeout in Windows registry that tells how much time the camera should stay on ? This is very strange as my code runs perfect when turning on/off the camera quickly enough (i.e. not letting the camera off more than ~15 seconds).

  • Service Application too visible

    - by Tom
    Working on a service application in Delphi 5 that is intended to run on Windows XP - 7. Most of the application is coming together nicely, but I'm running into one issue. Part of this service application is a form that displays data occasionally (similar to the slider box Avast uses to let you know its updated). When the service shows the form, the form displays on the taskbar, but we don't want it to. Does anyone have any suggestions as to how to hide the form's button on the taksbar? None of the standard methods I've found for regular applications have worked so far. Thanks.

  • mvc contrib pager question - AsPagination

    - by csetzkorn
    Hi, I might be wrong but is the AsPagination method not very inefficient as it sucks all the data from a repository first to initialise TotalItems etc.? So paging is not used to make the data access more efficient. I have not found any examples which use a repository and 'true' paging (i.e. uses TOP etc. in the atcual SQL). How do I use the Pager if I have a repository method with this signature: IList GetData(int? page, out int TotalItems) Any feedback would be very much appreciated. Thanks. Christian

  • Workaround for Outlook 2007 for wrapping text around image with margin?

    - by DavidW
    As we all know, Outlook 2007 uses the Word 2007 rendering engine, causing endless grief when designing HTML email message. [Insert rant here] In particular, float, margin, and padding are - shall we say? - poorly supported. To simulate float so that text wraps around an image, apparently we can simply use: <img src="foo.png" align="right"> The issue is padding/margin. Without padding/margin, the wrapped text butts up against the image which looks goofy. One workaround is to edit the image and add transparent framing that simulates margin. Does anyone know any other workarounds?

  • How does Task Parallel Library scale on a terminal server or in a web application?

    - by Lasse V. Karlsen
    I understand that the TPL uses work-stealing queues for its tasks when I execute things like Parallel.For and similar constructs. If I understand this correctly, the construct will spin up a number of tasks, where each will start processing items. If one of the tasks complete their allotted items, it will start stealing items from the other tasks which hasn't yet completed theirs. This solves the problem where items 1-100 are cheap to process and items 101-200 are costly, and one of the two tasks would just sit idle until the other completed. (I know this is a simplified exaplanation.) However, how will this scale on a terminal server or in a web application (assuming we use TPL in code that would run in the web app)? Can we risk saturating the CPUs with tasks just because there are N instances of our application running side by side? Is there any information on this topic that I should read? I've yet to find anything in particular, but that doesn't mean there is none.

  • How should I port this Prototype to JQuery?

    - by blu
    There is currently this Prototype code that does a PUT: new Ajax.Request(someUrl, { method: 'put', parameters: { 'foo': bar }, onSuccess: function(response) { } .bind(this) }); I found this post but the solution uses an extra parameter supported by RoR, however I am targeting an ASP.NET backend. I searched a bit and found that not all browsers support PUT operations so apparently this could fail in certain browsers? This is already in prod, so a direct port would be fine for now I suppose. As an aside, what is the deal with the bind(this) in the onSuccess function?

  • Non-graphical linearity estimation

    - by aL3xa
    In my previous post, I was looking for correlation ratio (η or η2) routines in R. I was surprised by the fact that no one uses η for linearity checking in the GLM procedures. Let's start form a simple example: how do you check linearity of bivariate correlation? Solely with scatterplot? There are several ways of doing this, one way is to compare linear and non-linear model R2, then to apply F test to seek for significant difference between them. Finally, the question is: How do you check linearity, the "non-grafical" way?

  • what's the UNC path for local computer from a remote machine ?

    - by KaluSingh Gabbar
    I am writing a small utility program in IronPython to install applications on remote machine using managementclass which uses WMI.

  • How should my application keep clients in sync with schema changes to HTML5 databases?

    - by Chad Johnson
    I'm wanting to incorporate HTML5 database storage into my web application to make it online-accessible. I've done lots of development in server-side environments with databases, and we all know that database schema additions and modifications are often necessary. I am wondering what should happen if my application uses an offline database schema, and that schema changes. How do I prevent the application from breaking on the client side? How do I ensure the database is always up to date on the client end? Anyone have any solutions?

  • wanting to move up from ms access, thinking .net? visual studio?

    - by Tristan Lear
    So I wrote a project-management program for a small business using Microsoft Access 2007. Now they've requested lots of additional features (timekeeping, privileged data tiers ...) I personally use Linux, but the whole office uses Windows. I'm relatively new to programming but like to teach myself using projects like this. I'm right on the edge on this -- I can't really tell what the path of least resistance here is: do I stay in access + VBA and teach myself a dying, annoying language -- while struggling against all the limitations of Access? Or do I move to something else? Python seems simple enough ... Whatever I use, i need to be able to offer a GUI.

  • Before after select event validation and results with jquery

    - by richbyte
    I am using a javascript function (F) (jquery )which uses 3 select values selected by the user to calculates a value - R(result) R is a number ranging from (1 through 9), (11) and (22); I need 2 extra steps one before the calculation and one after. a. Before calculation takes place: Make sure all three select values are changed before function(F) takes place. If not prompt the user with a notice ( create dom element/ I am using jquery) b. After the value R is calculated show an element corresponding to the result e.g. if R is 1 show an element ( a predetermined "link" element corresponding to each result value) thanks a lot.
