  • How do I access a JavaFX 1.3 static class member from Java?

    - by James
    I want to access a static JavaFX class member from Java using the Javafx reflection API. E.g. JavaFX code: var thing; class MyJavaFXClass { } Java code: private Object getThing() { FXClassType classType = FXContext.getInstance().findClass("mypackage.MyJavaFXClass"); // Get static member 'thing' from 'MyJavaFXClass' // <Insert Code Here> return thing; } What Java code do I need to access 'MyJavaFXClass.thing'? Note: I am using JavaFX 1.3 - I'm not sure if the reflection API is different here to earlier JavaFX versions.

  • WriteableBitmap in .NET 4

    - by Jamie
    Hi there, I have got a problem: I would like to use a method Render() for WriteableBitmap object. However, as I noticed, the method is not available without using a Silverlight assembly System.Windows.dll. I need to use RenderTargetBitmap in my project (PresentationCore assembly for standard .net). Here is the problem - there are definitions of some classes in both assemblies, thus they are in conflict. Basically, I need to add some stuff to Bgra32 bitmap. However, RenderTargetBitmap works only with Pbgra32 ones. I found that using WriteableBitmap to render would be nice. Maybe I am wrong? Do you have any ideas? Thank you in advance for the reply! Cheers

  • C# Windows Forms Print Dialog box click OK twice to respond

    - by sbartlett007
    I'm using Visual Studio 2008, .net Framework 3.5 for a Windows forms client-server app that I'm working on. There is a weird bug when I run the program and try to print. The print dialog box opens, but I have to click the OK button twice for it to work. After the second click it works fine, no errors. When I put a breakpoint on: if (result == DialogResult.OK) , the breakpoint doesn't trigger until the second click. Here is the code: private void tbPrint_Click(object sender, EventArgs e) { try { printDialog1.Document = pDoc; DialogResult result = printDialog1.ShowDialog(); if (result == DialogResult.OK) { pDoc.PrinterSettings.PrinterName = printDialog1.PrinterSettings.PrinterName; pDoc.Print(); } ... This is driving me crazy, and I can't see anything else that would interfere with it.

  • C# MDX RenderToSurface, where to reset after device is lost?

    - by Moritz Schöfl
    Hi, I got a problem with the RenderToSurface class. When I resize the Form of my Device, the Draw method is still called, but doesnt throw an Exception, it looks like this: device.Clear(ClearFlags.Target, Color.Red, 0, 0); device.BeginScene(); // here is out commented code device.EndScene(); device.Present(); In another method, I wrote this: renderToSurface.BeginScene(surfaces[currentIndex]); // here is out commented code renderToSurface.EndScene(Filter.None); and this method seems to throw a nullpointer exception when I resize the window; So my question is: - where to reset / restore / handle the renderToSurface class? (i tried it with the DeviceReset event like following - void OnDeviceReset(object sender, EventArgs e) { renderToSurface = new RenderToSurface(Game.Device, Game.ClientSize.Width, Game.ClientSize.Height, Format.A8R8G8B8, true, DepthFormat.D16); } )

  • difference in logging mechanism: API and application(python)

    - by zubin71
    I am currently writing an API and an application which uses the API. I have gotten suggestions from people stating that I should perform logging using handlers in the application and use a "logger" object for logging from the API. In light of the advice I received above, is the following implementation correct? class test: def __init__(self, verbose): self.logger = logging.getLogger("test") self.logger.setLevel(verbose) def do_something(self): # do something self.logger.log("something") # by doing this i get the error message "No handlers could be found for logger "test" The implementation i had in mind was as follows: #!/usr/bin/python """ .... .... create a logger with a handler .... .... """ myobject = test() try: myobject.do_something() except SomeError: logger.log("cant do something") Id like to get my basics strong, id be grateful for any help and suggestions for code you might recommend I look up. Thnkx!

  • Custom certificate as proof of transaction

    - by Andy
    I'm developing a site where a user conducts a given transaction and once completed, the user is issued with a 'secure certificate'. The certificate serves as proof of the transaction and the user is able to upload the certificate at a later stage, to view the details of the transaction. At the moment I'm using a custom XML document with encrypted fields. It works perfect, but I would like a standardized approach, such as an X.509 certificate. I'm no encryption expert, but from what I gather, X.509 is more geared towards SSL issued by a CA. Is it possible to create your own valid valid CRT file? As a test, I created a CRT file with the example provided on WikiPedia. However, when I open the file in Windows I get this warning: Invalid Public Key Security Object File - This file is invalid as the following: Security Certificate. Not having much luck here, so time to ask the experts. What direction should I be heading in? Any guidance would be greatly appreciated.

  • Opening read-only OLEDB connection to MS Access back-end database while allowing updates via separat

    - by djdilicious
    I have a back-end MS Access 2002-2003 database which stores blog entries. I created a separate front-end database with the forms for entering blog posts into the backend database. Finally, I have a website utilizing ASP to display the blog entries. The website connects directly to the backend database using an OLEDB connection object. Whenever I open the form for creating a new post in MS Access, loading the blog post page on the website displays the error: Could not use "; file already in use. I would like to be able to display the older blog posts even though the newest one is in the process of being added.

  • ASP.NET AjaxControlToolkit change Combobox content dynamically per Ajax

    - by Ulli
    If I understand it right the new ACT ComboBox Control is Bound once to a given Datasource. But the count of the records I want to bind is very large. So I want to load the content of the ComboBox List via Ajax after the user typed in a few charachters. So at page load the combobox list should be empty and if something is typed in the list is loaded with the typed text as search text. I tried this: <asp:ComboBox ID="cbxCompany" DropDownStyle="DropDownList" runat="server" AutoCompleteMode="Append" /> Protected Sub cbxCompany_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbxCompany.TextChanged Dim dt As DataTable = GetCompanies(cbxCompany.Text) cbxCompany.DataSource = dt cbxCompany.DataTextField = "nameout" cbxCompany.DataValueField = "cid" cbxCompany.DataBind() End Sub GetCompanies is my method for getting data from the database, the parameters filters the select statement. But this doesn't work. Is there a way to reload the combobox content per Ajax?

  • Memory footprint of a parsed XML file in Classic ASP?

    - by Pete Duncanson
    Anyone know of a way to find out the amount of memory/size of a XMLDocument once it has parsed a XML file? I've been doing "beer mat" calculations so far but have been asked to come up with some more legit numbers through monitoring some how. I need to create about 1500 XML files (via FreeThreadedXMl-DOM object), which verge between 3-9K in size and store them in Application vars but our SysAdmin is worried about us gobbling up too much memory. Other than the crude method of booting up a fresh IIS instance and then loading everything in and monitoring before and after memory usage in Task Manager I can't think of a way of doing it with a bit more accuracy.

  • On reference_wrapper and callable objects

    - by Nicola Bonelli
    Given the following callable object: struct callable : public std::unary_function &lt;void, void&gt; { void operator()() const { std::cout << "hello world" << std::endl; } }; a std::tr1::reference_wrapper< calls through it: callable obj; std::tr1::ref(obj)(); Instead, when the operator() accepts an argument: struct callable : public std::unary_function &lt;int, void&gt; { void operator()(int n) const { std::cout << n << std::endl; } }; std::tr1::bind accepts a reference_wrapper to it as a callable wrapper... callable obj; std::tr1::bind( std::tr1::ref(obj), 42 )(); but what's wrong with this? std::tr1::ref(obj)(42);

  • Solving iPhone/iPad out of memory issues

    - by Joonas Trussmann
    I have a strange issue where I'm scrolling through a paged UIScrollView which displays the pages of a PDF document (using Quartz 2D and CATiledLayer). When I page through memory allocation looks fine with it going up with a few initial pages and then keeping it steady as it obviously releases the memory kept for earlier pages. Upon hitting page x (not a certain PDF page or a certain number per se) memory usage goes from a couple of megs to 308 megs and the app crashes. So my question is: how to best try to find what's causing this? The object alloc tool in instruments shows the memory as simply going to malloc. (in huge chunks).

  • Ruby Rack: startup and teardown operations (Tokyo Cabinet connection)

    - by clint.tseng
    I have built a pretty simple REST service in Sinatra, on Rack. It's backed by 3 Tokyo Cabinet/Table datastores, which have connections that need to be opened and closed. I have two model classes written in straight Ruby that currently simply connect, get or put what they need, and then disconnect. Obviously, this isn't going to work long-term. I also have some Rack middleware like Warden that rely on these model classes. What's the best way to manage opening and closing the connections? Rack doesn't provide startup/shutdown hooks as I'm aware. I thought about inserting a piece of middleware that provides reference to the TC/TT object in env, but then I'd have to pipe that through Sinatra to the models, which doesn't seem efficient either; and that would only get be a per-request connection to TC. I'd imagine that per-server-instance-lifecycle would be a more appropriate lifespan. Thanks!

  • Adding Item to DataBound Drop Down List

    - by Stephen
    Yes, I have read most of the topics here, but I can't find an answer that works. I have Three drop-down lists. The first is databound to grab distinct experiment names. The user selects, page posts back, and the second drop-down menu displays distinct time points. This is where I need help. I need to add an item to THAT drop-down list whose ID, DataTextField, DataValueField are all TimePt. Seems simple, but I can't get it to work. protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack) { TimePt.DataSource = TimePTDD; TimePt.DataValueField = "TimePt"; TimePt.DataTextField = "TimePt"; TimePt.DataBind(); TimePt.Items.Insert(0, new ListItem("--Select---", "0")); TimePt.SelectedIndex = 0; } } I'm missing sometthing.

There are two classes A and B I am binding the item source of a listbox to A and i have defined a command in B and i need this command to bind with the button present inside the listbox.(ie..listbox-listboxitem-button) Is there any way to bind to a property outside of the current data context?

  • Is it possible to build a JPA entity by extending a POJO?

    - by Freiheit
    Lets say I have the following POJO: public class MyThing { private int myNumber; private String myData; //assume getter/setter methods } Is it now possible to extend this POJO as a JPA entity? @Entity @Table(name = "my_thing") public class MyThingEntity extends MyThing implements Serializable { @Column(name = "my_number") //????????? @Column(name = "my_data") //???????? } I want to keep the POJO separate from the JPA entity. The POJO lives in a different project and is often used without a persistence layer, my project wants to persist it in a database and do so without the overhead of mapping from a POJO to an entity and back. I understand that JPA entities are POJOs, but in order to use it I would have to include a library that implements javax.persistence and the other projects using the same base object have no use for a persistence layer. Is this possible? Is this a good idea?

  • Is SynchronizationContext.Post() threadsafe?

    - by cyclotis04
    This is a pretty basic question, and I imagine that it is, but I can't find any definitive answer. Is SynchronizationContext.Post() threadsafe? I have a member variable which holds the main thread's context, and _context.Post() is being called from multiple threads. I imagine that Post() could be called simultaneously on the object. Should I do something like lock (_contextLock) _context.Post(myDelegate, myEventArgs); or is that unnecessary? Edit: MSDN states that "Any instance members are not guaranteed to be thread safe." Should I keep my lock(), then?

  • ASP.NET SetAuthCookie Impersonation Help

    - by rlb.usa
    Hello SO, I'm trying to do user impersonation for a web application we have. The user selects the user they'd like to emulate/impersonate and then clicks the button which fires this: protected void uxImpersonate_Click(object sender, EventArgs e) { ... FormsAuthentication.SetAuthCookie(uxUserToEmulate.SelectedValue, false); Response.Redirect("Impersonation.aspx"); //reload page manually } We have a dev - test - production server environment and on two servers this works just fine, but on another one, in all browsers, it kicks me to the login screen. What's going on and how can I fix it? We're on ASP.NET 2.0, and I'm using http://stackoverflow.com/questions/549016/user-impersonation-with-asp-net-forms-authentication as a guide. UPDATE: It appears that the user actually is impersonated successfully but is loosing their Role as admin (only Admin Role's can access this impersonation page).

  • Centralized Credentials Service For Various Apps

    - by Vlad
    We are researching the possibility to build a centralized credentials storage for internal applications. These apps (vb6, vb.net, web apps in asp.net, etc) are using various instances of SQL servers and iSeries. We want to implement a central credentials facility that would act as a security broker. Basically it should work like this: Client app supplies AppID (I am Sales Application) and EnvironmentID (I am running in QA environment) and in return will get either a connection object (preferred) or encrypted connection string that will allow said application to connect to resources it needs. There will be cases when application needs to connect to two (or more) database resources (i.e. to SQL and iSeries). What are looking at DP API at the moment, but I am not convinced that DP API is the solution as it tied in with machine key. In our case using machine key isn't feasible, so I want to know if there are other approaches available.

  • Asp.Net MVC2 TekPub Starter Site methodology question

    - by Pino
    Ok I've just ran into this and I was only supposed to be checking my emails however I've ended up watching this (and not far off subscribing to TekPub). http://tekpub.com/production/starter Now these app is a great starting point, but it raises one issue for me and the development process I've been shown to follow (rightly or wrongly). There is no conversion from the LinqToSql object when passing data to the view. Are there any negitives to this? The main one I can see is with validation, does this cause issues when using MVC's built in validation as this is somthing we use extensivly. Because we are using the built in objects generated by LinqToSql how would one go about adding validation, like [Required(ErrorMessage="Name is Required")] public string Name {get;set;} Interested to understand the benifits of this methodology and any negitives that, should we take it on, experiance through the development process.

  • Custom Attributes on Class Members

    - by ccook
    I am using a Custom Attribute to define how a class's members are mapped to properties for posting as a form post (Payment Gateway). I have the custom attribute working just fine, and am able to get the attribute by "name", but would like to get the attribute by the member itself. For example: getFieldName("name"); vs getFieldName(obj.Name); The plan is to write a method to serialize the class with members into a postable string. Here's the test code I have at this point, where ret is a string and PropertyMapping is the custom attribute: foreach (MemberInfo i in (typeof(CustomClass)).GetMember("Name")) { foreach (object at in i.GetCustomAttributes(true)) { PropertyMapping map = at as PropertyMapping; if (map != null) { ret += map.FieldName; } } } Thanks in advance!
