  • I'm trying to display records from a database and then when a new one is added automatically update

    - by Pete
    I'm trying to display records from a database and then when a new one is added automatically update the displayed records from the database with the new one I am doing this using php and javascript. I want to load a page and display tags under a video and then when a user adds a new tag by entering it into text box to add it to the database and then refresh the part of the page which shows these tags and include the new one which has just been added all without the page being reloaded. Thanks in advance for any help

    Is there a way to modify the code from a previous answer import groovy.xml.MarkupBuilder def writer = new StringWriter() def builder = new MarkupBuilder(writer) def awaiting = ['one', 'two', 'three'] builder.html { ul { awaiting.each { li(it.toString()) } } } println writer.toString() so that if you add a tag instead that you send it - like builder.html{ tag{ awaiting.each{} } } return result could be 'ol' or 'ul' for example

  • Ruby on Rails testing: How can I test or at the very least see a form_for's error_messages_for?

    - by williamjones
    I'm working on creating a tests, and I can't figure out why the creation of a model from a form_for is failing in the test but works in real browsers. Is there a straightforward way for me to see what the problems are in the model creation? Even better would be, is there a straightforward way for me to test the error outputs that I access via error_messages_for? In that case, I'd like to also add in tests that make sure that malformed forms are outputting the correct errors.

  • SVN: Nested repo

    - by Extrakun
    We are working with a PHP application which has no concept of switch-able themes; the situation is that we are modifying the application to add our own features, and CSS/Smarty templates for our own look and feel. We have 2 projects base on this application, each with a different layout/presentation. Hence I need to have one repo for the base application files, and one for the CSS/smarty templates. How should I go about doing this?

  • Using UCMA to connect to 3CX?

    - by Rodney Burton
    Has anyone used Microsoft's UCMA 2.0 SDK to connect to 3CX's free IP PBX to add voice capabilities to their application? If so, does it work? What I am trying to accomplish is having a windows form app running on 2 or more computers, and each person can connect to another person and carry on a voice conversation using their headset connected to their computer. App is in C# w/ .NET3.5 SP1.

  • Normalization of database for timesheet tool and ensure data integrity

    - by fireeyedboy
    I'm creating a timesheet application. I have the following entities (amongst others): Company Employee = an employee associated with a company Client = a client associated with a company So far I have the following (abbreviated) database setup: Company - id - name Employee - id - companyId (FK to Company.id) - name Client - id - companyId (FK to Company.id) - name Now, I want an employee to be associated with a client, but only if that client is associated with the company the employee works for. How would you guarantee this data integrity on a database level? Or should I just depend on the application to guarantee this data integrity? I thought about creating a many to many table like this: EmployeeClient - employeeId (FK to Employee.id) - companyId \ (combined FK to Client.companyId, Client.id) - clientId / Thus, when I insert a client for an employee along with the employee's company id, the database should prevent this when the client is not associated with the employee's company id. Does this make sense? Because this still doesn't guarantee the employee is associated with the company. How do you deal with these things? UPDATE The scenario is as followed: A company has multiple employees. Employees will only be linked to one company. A company has multiple clients also. Clients will only be linked to one company. (Company is a sandbox, so to speak). An employee of a company can be linked to a client of it's company, but only if the client is part of the company's clientele. In other words: The application will allow a company to create/add employees and create/add clients (hence the companyId FK in the Employee and Client tables). Next, the company will be allowed to assign certain clients to certain of it's employees (EmployeeClient table). Imagine an employee working on projects for a few clients for which s/he can write billable hours, but the employee must not be allowed to write billable hours for clients they are not assigned to by their employer (the company). So, employees will not automatically have access to all their company's clients, but only to those that the company has selected for them. Hopefully this has shed some more light on the matter.

  • Visual Studio 2010 - References Dialog Filter

    - by Sphynx
    Visual Studio 2010 adds a new feature to improve loading speed of references in "Add .NET Reference" tab. For example, when the target framework of project is 3.5, it displays only 3.5 assemblies in the list, and says "Filtered to: .NET Framework 3.5". This feature is quite annoying, as it makes impossible to find an older assembly, unless you change a target framework in compilation options. Is there any option to disable that filtering?

  • c# interop with ghostscript

    - by yodaj007
    I'm trying to access some Ghostscript functions like so: [DllImport(@"C:\Program Files\GPLGS\gsdll32.dll", EntryPoint = "gsapi_revision")] public static extern int Foo(gsapi_revision_t x, int len); public struct gsapi_revision_t { [MarshalAs(UnmanagedType.LPTStr)] string product; [MarshalAs(UnmanagedType.LPTStr)] string copyright; long revision; long revisiondate; } public static void Main() { gsapi_revision_t foo = new gsapi_revision_t(); Foo(foo, Marshal.SizeOf(foo)); This corresponds with these definitions from the iapi.h header from ghostscript: typedef struct gsapi_revision_s { const char *product; const char *copyright; long revision; long revisiondate; } gsapi_revision_t; GSDLLEXPORT int GSDLLAPI gsapi_revision(gsapi_revision_t *pr, int len); But my code is reading nothing into the string fields. If I add 'ref' to the function, it reads gibberish. However, the following code reads in the data just fine: public struct gsapi_revision_t { IntPtr product; IntPtr copyright; long revision; long revisiondate; } public static void Main() { gsapi_revision_t foo = new gsapi_revision_t(); IntPtr x = Marshal.AllocHGlobal(20); for (int i = 0; i < 20; i++) Marshal.WriteInt32(x, i, 0); int result = Foo(x, 20); IntPtr productNamePtr = Marshal.ReadIntPtr(x); IntPtr copyrightPtr = Marshal.ReadIntPtr(x, 4); long revision = Marshal.ReadInt64(x, 8); long revisionDate = Marshal.ReadInt64(x, 12); byte[] dest = new byte[1000]; Marshal.Copy(productNamePtr, dest, 0, 1000); string name = Read(productNamePtr); string copyright = Read(copyrightPtr); } public static string Read(IntPtr p) { List<byte> bits = new List<byte>(); int i = 0; while (true) { byte b = Marshal.ReadByte(new IntPtr(p.ToInt64() + i)); if (b == 0) break; bits.Add(b); i++; } return Encoding.ASCII.GetString(bits.ToArray()); } So what am I doing wrong with marshaling?

  • ASP.NET - Trailing Slash and Tilde

    - by Echilon
    I've found what seems like a bizarre problem with IIS 6.0 and .NET 3.5. I always use the tilde for all URLs (eg: ~/mypage.aspx) so if I go to mydomain.com/mypage.aspx, everything works fine. If, however, I add a trailing slash and go to mydomain.com/mypage.aspx/, all links on the page which use the tilde get rendered as mydomain.com/mypage.aspx/otherpage.aspx instead of mydomain.com/otherpage.aspx. This happens with all controls. Has anyone had this issue before?

  • Specify default WCF endpoint in app.config

    - by Nelson
    When you add a service reference it creates the class "MyServiceClient" with a default constructor. If I use new MyServiceClient() I get an error: Could not find default endpoint... If I use new MyServiceClient("endpointName") it works. I would like to specify a default endpoint in app/web.config which will get used when I use the default constructor. I know I can place that default name in *.settings which ends up in app.config, but just wondering if there is any built-in way to do it.

  • Adding comments to SVN revisions

    - by pako
    I'm using Subversion 1.6 and WebSVN. I'm looking for a simple tool, that would enable me to add custom comments to SVN revisions. So I would be able to see the stream of incoming revisions and mark which of them I already reviewed. An ability to share the comments with other programmers would also be a welcome addition, but it's not necessary. Could you recommend any tools for this?

  • IE8 web slice - CSS problem

    - by rjovic
    Again me with IE8 web slice :) This time i have following problem. I created web slice for IE8 and created button for users where they can choice to add it to their browsers. Code is : <input class="add" type="button" value="Dodaj Xica web slice u IE8!" onclick='window.external.AddToFavoritesBar("http://localhost:51914/Home/GetWebSlice", "xica.rjovic.com", "slice");' /> There is everything fine, and web slice is added to IE8 and web page is displayed correct. But I have problem with CSS in web slice. I defined css in it, but when web slice i rendered there are only black fonts without any css properties. My web slice is defined as : <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>GetWebSlice</title> <style type="text/css"> p {color: white; } body {background-color: blue; } .container {background-color: red;} </style> </head> <body> <div class="hslice container" id="xica"> <h2 class="entry-title container">Xica web slice</h2> <div class="entry-content"> <h2>Saldo : <b><%= ViewData["total"] %></b></h2> <p><%= ViewData["cardNumber"] %></p> <p>Status : <%= ViewData["status"] %></p> </div> </div> </body> </html> When I try to see web slice directly in my browser then everything is ok, and css is show as expected. Thank you...! EDIT : here is the picture of problem : http://www.deviantpics.com/share-2F10_4BD73E25.html

  • Trying to write a loop that uses an OutputStream to write to a text file.

    - by Steve McLain
    I'm not a java programmer, I'm a VB programmer. I am doing this as part of an assignment, however, I'm not asking for help on something assignment related. I'd like to figure out how to get the OutputStreamWriter to work properly in this instance. I just want to capture the values I'm generating and place them into a text document. The file is generated, but only one entry exists, not the 40 I'm expecting. I could do this in a heartbeat with VB, but java feels very strange to me right now. Your help is appreciated. Thanks, Steve Here's the code: public static void main(String[] args){ long start, end; double result,difference; try {//OutputStream code assistance from http://tutorials.jenkov.com/java-io/outputstreamwriter.html OutputStream outputStream = new FileOutputStream("c:\\Temp\\output1.txt"); Writer out = new OutputStreamWriter(outputStream); for(int n=1; n<=20; n++){ //Calculate the Time for n^2. start = System.nanoTime(); //Add code to call method to calculate n^2 result = mN2(n); end = System.nanoTime(); difference = (end - start); //Output results to a file out.write("N^2 End time: " + end + " Difference: " + difference + "\n"); out.close(); } } catch (IOException e){ } try { OutputStream outputStream = new FileOutputStream("c:\\Temp\\output1.txt"); Writer out = new OutputStreamWriter(outputStream); for(int n=1; n<=20; n++){ //Calculate the Time for 2^n. start = System.nanoTime(); //Add code to call method to calculate 2^n result = m2N(n); end = System.nanoTime(); difference = (end - start); //Output results to a file out.write("N^2 End time: " + end + " Difference: " + difference + "\n"); out.close(); } } catch (IOException e){ } } //Calculate N^2 public static double mN2(double n) { n = n*n; return n; } //Calculate 2N public static double m2N (double n) { n = 2*n; return n; }

    Hello everybody We are having trouble with having a generalized approach to committing with a batch file using commandline svn. We've got a backupscript that created a new folder with the current date containing the database dumps of our database. (Yes, we version control our database). Now how can I use the svn commit command to include all directories that are new in the project? Is there an approach without using the svn add command?` Thanks for all advice!

  • Using Entity Framework (code first) migrations in production

    - by devdigital
    I'm just looking into using EF migrations for our project, and in particular for performing schema changes in production between releases. I can see that generating SQL (delta) script files is an option, but is there no way of running the migrations programmatically on app start up? Will I instead need to add each delta script to the solution and write my own framework to apply them in order (from the current version to the latest) on bootstrap?
