  • XSD problem: The value of attribute on element is not valid with respect to its type

    - by Tom Brito
    (First of all, I'm trying to learn how to handle xsd files, I know very little) I got this xsd, and just copy to Eclipse IDE, and it says there an error on line 26: <xs:element name="Issuer" type="dkx:IssuerType" /> saying: cvc-attribute.3: The value 'dkx:IssuerType' of attribute 'type' on element 'xs:element' is not valid with respect to its type, 'QName'. Any idea what is this? (as this is an example file, I'm assuming it is an independent file, hope it is)

  • How can I write to a single xml file from two programs at the same time?

    - by Tom Bushell
    We recently started working with XML files, after many years of experience with the old INI files. My coworker found some CodeProject sample code that uses System.Xml.XmlDocument.Save. We are getting exceptions when two programs try to write to the same file at the same time. System.IO.IOException: The process cannot access the file 'C:\Test.xml' because it is being used by another process. This seems obvious in hindsight, but we had not anticipated it because accessing INI files via the Win32 API does not have this limitation. I assume there's some arbitration done by the Win32 calls that work at a higher level than the the XmlDocument.Save method. I'm hoping there are higher level XML routines somewhere in the .Net library that work similarily to the Win32 functions, but don't know where to start looking. Or maybe we can set up our file access permissions to allow multiple programs to write to the same file? Time is short (like almost all SW projects), and if we can't find a solution quickly, we'll have to hold our noses and go back to INI files.

  • Using write to print floating point numbers.

    - by Tom

  • How to get the field name of a java (weak) reference pointing to an object in an other class?

    - by Tom
    Imagine I have the following situation: Test1.java import java.lang.ref.WeakReference; public class Test1 { public WeakReference fieldName; public init() { fieldName = new WeakReference(this); Test2.setWeakRef(fieldName); } } Test2.java import java.lang.ref.WeakReference; public class Test2 { public static setWeakRef(WeakReference weakRef) { //at this point I got weakRef in an other class.. now, how do I get the field name this reference was created with? So that it returns exactly "fieldName", because that's the name I gave it in Test1.java? } } At the location of the comment I received the weak reference created in an other class. How would I retreive the field name that this weak reference was created with, in this case "fieldName"? Thanks in advance.

  • Implicit linking vs. explicit linking of DLL in Delphi

    - by Tom
    I'm having trouble getting my dll to work when using explicit linking. Using implicit linking it works fine. Would someone google me a solution? :) No, just kidding, here's my code: This code works fine: function CountChars(_s: Pchar): integer; StdCall; external 'sample_dll.dll'; procedure TForm1.Button1Click(Sender: TObject); begin ShowMessage(IntToStr(CountChars('Hello world'))); end; This code doesn't work (I get an access violation): procedure TForm1.Button1Click(Sender: TObject); var LibHandle: HMODULE; CountChars: function(_s: PChar): integer; begin LibHandle := LoadLibrary('sample_dll.dll'); ShowMessage(IntToStr(CountChars('Hello world'))); // Access violation FreeLibrary(LibHandle); end; This is the DLL code: library sample_dll; uses FastMM4, FastMM4Messages, SysUtils, Classes; {$R *.res} function CountChars(_s: PChar): integer; stdcall; begin Result := Length(_s); end; exports CountChars; begin end.

  • Adding a view with a view controller as a subview of another view controller. Doesn't work.

    - by Tom
    I'm trying to essentially re-implement the UISplitViewController (because it has its limits), but when I create a UIViewController viewController, and then do an "[viewController.view addSubview contentViewController.view]" on it, to add a view that already has a view controller, that content view doesn't seem to get initialised by its view controller. I guess its view controller is getting detached or deallocated, is this the case?

  • C Remove the first line from a text file without rewriting file

    - by Tom Van den Bon
    Hi, I've got a service which runs all the time and also keeps a log file. It basically adds new lines to the log file every few seconds. I'm written a small file which reads these lines and then parses them to various actions. The question I have is how can I delete the lines which I have already parsed from the log file without disrupting the writing of the log file by the service? Usually when I need to delete a line in a file then I open the original one and a temporary one and then I just write all the lines to the temp file except the original which I want to delete. Obviously this method will not word here. So how do I go about deleting them ?

  • Multiple dropdown combination check and filter

    - by Tom
    Using Javascript / jQuery, I'm trying to build a "combination checker" that will take the values of three (but can be more) dropdown lists and filter the options based on a supplied list of allowed combinations. For example: DROPDOWNS Field 1: - value_1 - value_2 Field 2: - value_3 Field 3: - value_4 - value_5 COMBINATIONS - value_1, value_3, value_5 - value_1, value_3, value_4 - value_2, value_3, value_5 When a user selects Field 3 - value_4, the unavailable options will be disabled - ie, Field 1 - value_2 (there is no combination that allows value_2 and value_4 to be selected together). It would be really great if someone could provide some pointers on how this can be achieved or just provide a fresh perspective - I'm going round in circles on this one!

  • Weird code appearing when I loop over model instances in Rails

    - by Tom Maxwell
    In my Rails app I'm trying to loop over the Submission instances inside my Folder instances with Rails templating code. It works. However, it's also returning each instance in code which doesn't seem to be JSON. It's what's returned when you look up an instance in the Rails console. Here's an example: #<Submission id: 112, title: nil, content: nil, created_at: "2013-10-10 23:29:39", updated_at: "2013-10-10 23:29:39", user_id: 1, folder_id: 1, parent_id: nil> Here's what the code looks like for the loop: <%= @folder.submissions.each do |x| %> <% if x.title != nil %> <div id="<%= x.id %>" class="submission-textual"> <h1><%= x.title %></h1> </div> <% else %> <% end %> <% end %> I checked my Folder and Submissions controllers but am not sure what this is. Why are these strings being rendered whenever I try and render an instance in my view? I'm still new to Ruby so that explains why I haven't seen this.

  • Why jquery.animate on a textarea make the blinking cursor disapears?

    - by Tom S.
    Hello everyone. I have the following code $(document).ready(function() { $("#myTextArea").focus(function() { $("#myTextArea").animate({ "height": "75px"}, "normal"); return false; }); to expand a textbox when it gets focus. The expand occurs, however the blinking cursor disapears, at least in Firefox! Edited: The textarea is still focused, and i can type on it. Why does this happen? Is there a way to show it again? Thanks in advance

    I'd like to set up daily tarballs/zip archives on my host for an SVN of a related project. I do not have access to their server, however they do have a publicly accessible SVN. How would I grab this SVN and build archives with minimal load ( dreamhost shared ), via Cron task + php/shell script?

  • JList with JScrollPane and prototype cell value wraps element names (replaces with dots instead of s

    - by Tom
    I've got a Jlist inside a JScrollPane and I've set a prototype value so that it doesn't have to calculate the width for big lists, but just uses this default width. Now, the problem is that the Jlist is for some reason replacing the end of an element with dots (...) so that a horizontal scrollbar will never be shown. How do I disable with "wrapping"? So that long elements are not being replaced with dots if they are wider than the Jlist's width? I've reproduced the issue in a small example application. Please run it if you don't understand what I mean: import javax.swing.*; import java.awt.*; public class Test { //window private static final int windowWidth = 450; private static final int windowHeight = 500; //components private JFrame frame; private JList classesList; private DefaultListModel classesListModel; public Test() { load(); } private void load() { //create window frame = new JFrame("Test"); frame.setSize(windowWidth, windowHeight); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setUndecorated(true); frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG); //classes list classesListModel = new DefaultListModel(); classesList = new JList(classesListModel); classesList.setPrototypeCellValue("prototype value"); classesList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); classesList.setVisibleRowCount(20); JScrollPane scrollClasses = new JScrollPane(classesList, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); for (int i = 0; i < 200; i++) { classesListModel.addElement("this is a long string, does not fit in width"); } //panel JPanel drawingArea = new JPanel(); drawingArea.setBackground(Color.white); drawingArea.add(scrollClasses); frame.add(drawingArea); //set visible frame.setVisible(true); } } Even if you force horizontal scrollbar, you still won't be able to scroll because the element is actually not wider than the width because of the dot (...) wrapping. Thanks in advance.

  • Cannot open a .tif with color using .Net Image or Bitmap classes

    - by Tom Regan
    I am attempting to open .tif files that have color in them (300 dpi, PixelFormat.Format24bppRgb) using the .Net Image and Bitmap classes. I always get an "invalid parameter" error when the tiffs have color (works fine for black and white tiffs). If anyone has source code on how to open a .tif with color in it I'd deeply appreciate it. Below is what I'm attempting to do; this also fails when calling Bitmap.FromStream: using (FileStream fs = File.OpenRead(fileName)) { using (Image img = Image.FromStream(fs)) {} }

  • How to make a DIV auto height resizable even if the content is absolute?

    - by Tom
    Hi, i have a container div which is position:relative and the squares are position:absolute because i want to play with their positions. Like what you see, the container does not fit the content except if the squares are positioned in Relative, is there a solution for this? I don't want to just set the height for container because the squares are not static so i want something that resizes automatically. Thanks

  • Is it possible in .NET to set the local endpoint (IP address) when using webclient to consume a web

    - by Tom
    I'm wondering if it is possible using .NET to call a remote web service and in effect specify which IP the call is made on. I'm consuming a service that limits the number of calls I can make based on IP. The service costs in the 20k range after the free limit is used up. I'm very close to enough calls but not quite there using the free service. My server has 3 IP so I could in effect triple the number of calls I could make to the remote service by changing the IP.

  • Django Forms: TimeField Validation

    - by Tom
    I feel like I'm missing something obvious here. I have a Django form with a TimeField on it. I want to be able to allow times like "10:30AM", but I cannot get it to accept that input format or to use the "%P" format (which has a note attached saying it's a "Proprietary extension", but doesn't say where it comes from). Here's the gist of my form code: calendar_widget = forms.widgets.DateInput(attrs={'class': 'date-pick'}, format='%m/%d/%Y') time_widget = forms.widgets.TimeInput(attrs={'class': 'time-pick'}) valid_time_formats = ['%P', '%H:%M%A', '%H:%M %A', '%H:%M%a', '%H:%M %a'] class EventForm(forms.ModelForm): start_date = forms.DateField(widget=calendar_widget) start_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats) end_date = forms.DateField(required=False, widget=calendar_widget) end_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats) description = forms.CharField(widget=forms.Textarea) Any time I submit "10:30AM", I get a validation error. The underlying model has two fields, event_start and event_end, no time fields, so I don't think the problem is in there. What stupid thing am I missing?

  • C# is there a problem with division?

    - by Tom
    This is a piece of my code, it is called every second, after about 10 seconds the values start to become weird (see below): double a; double b; for (int i = 0; i < currAC.Length; i++ ) { a = currAC[i]; b = aveACValues[i]; divisor = (a/b); Console.WriteLine("a = " + a.ToString("N2") + "\t" + "b = " + b.ToString("N2")); Console.WriteLine("divisor = " + divisor); Console.WriteLine("a+b = " + (a+b)); } and the output: a = -0.05 b = 0.00 divisor = 41 a+b = -0.0524010372273268 currAC and aveACValues are double[] what on earth is going on???? The addition result is correct every time, but the division value is wrong, yet it is reading a and b correctly?? EDIT: '41' is the value of the first calculation, ie when a = currAC[0], but this should not remain???

  • C# rotate a string 180 degrees

    - by Tom
    Hi im having a few problems rotating a string, i found that you need graphics.rotate() but when i change the rotation, i cannot even see the string. It appears the pivot point has completely thrown me. Also i saw an example with transform but i decided i did not need this? If my string was a graph label, reading top to bottom and i needed to rotate it 180 degrees so that it read bottom to top, how would i do this? Thanks in advance

  • What is the most popular generic collection data structure library for C?

    - by Tom Dalling
    I'm looking for a C library that provides generic collection data structures such as lists, associative arrays, sets, etc. The library should be stable and well tested. I'm basically looking for something better than the crappy C standard library. What C libraries fit this description? EDIT: I'd prefer that the library was cross-platform, but failing that, anything that works on Mac/Linux.

  • Resources for setting up a Visual Studio/C++ development environment

    - by Tom H.
    I haven't done much "front-end" development in about 15 years since moving to database development. I'm planning to start work on a personal project using C++ and since I already have MSDN I'll probably end up doing it in Visual Studio 2010. I'm thinking about using Subversion as a version control system eventually. Of course, I'd like to get up and running as quickly as I can, but I'd also like to avoid any pitfalls from a poorly organized project environment. So, my question is, are there any good resources with common best practices for setting up a development environment? I'm thinking along the lines of where to break down a solution into multiple projects if necessary, how to set up a unit testing process, organizing resources, directories, etc. Are there any great add-ons that I should make sure I have set up from the start? Most tutorials just have one simple project, type in your code and click on build to see that your new application says, "Hello World!". This will be a Windows application with several DLLs as well (no web development), so there doesn't need to be a deploy to a web server kind of process. Mostly I just want to make sure that I don't miss anything big and then have to extensively refactor because of it. Thanks!

  • "Invalid assignment" error from == operator

    - by Tom
    I was trying to write a simple method: boolean validate(MyObject o) { // propertyA && propertyB are not primitive types. return o.getPropertyA() == null && o.getPropertyB() == null; } And got a strange error on the == null part: Syntax error on token ==. Invalid assignment operator. Maybe my Java is rusty after a season in PLSQL. So I tried a simpler example: Integer i = 4; i == null; // compile error: Syntax error on token ==. Invalid assignment operator. Integer i2 = 4; if (i == null); //No problem How can this be? I'm using jdk160_05. To clarify: I'm not trying to assign anything, just do an && operation between two boolean values. I don't want to do this: if (o.propertyA() == null && o.propertyB() == null) { return true; } else { return false; }
