  • Cannot load JRubyEngine because org.apache.bsf.util.BSFEngineImpl not found

    - by Ceilingfish
    Hi, I'm trying to use JRuby in a custom application, and I don't seem to be able to load the JRubyEngine object. My class looks like functionally similar to this: public class ScriptEngine { private static ScriptEngine engine = new JRubyEngine(); public void run(final String script, final Map<String,Object> input) { final Bindings context = engine.createBindings(); context.putAll(input); try { engine.eval(script,context); } catch (ScriptException e) { log.error("Failed to execute script: "+getScript(),e); } } } However this fails at compilation with the complaint: [javac] Compiling 486 source files to /workspace/myProject/build/src [javac] /workspace/myProject/src/net/ceilingfish/ScriptEngine.java:31: cannot access org.apache.bsf.util.BSFEngineImpl [javac] class file for org.apache.bsf.util.BSFEngineImpl not found [javac] private static ScriptEngine engine = new JRubyEngine(); [javac] ^ [javac] 1 error Does anyone have any insights on where I can get this class from? Or if there is a better way to be instantiating a JRubyEngine object.

  • WCF: limit number of calls per hour - per user

    - by Eric Eijkelenboom
    Hi guys, I've got a WCF service (basicHttpBinding, basic authentication, IIS 6.0) on which I want to restrict the number of calls per hour - on user basis. For example, max 1000 calls per user, per hour (a la Google Maps, etc). I also want to implement some sort of subscription mechanism, so that users can upgrade their call-limit across various 'price plans'. I know that I could achieve this with a custom Inspector, backed by a DB containing some sort of 'subscription' table and a counter, but I'd like to avoid reinventing the wheel. Does anyone have experience doing this? Are there 3rd party projects/libraries that support this out of the box? Thanks. Eric

  • Getting the version of a COM object

    - by Shao
    I am accessing a .NET COM object from C++. I want to know the version information about this COM object. When I open the TLB in OLEVIEW.exe I can see the version information associated with the coclass. How can I access this information from C++? This is the information I get: [ uuid(XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX), version(1.0), custom(XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX, XXXX) ] coclass XXXXXXXX{ [default] interface XXXXXXXX; interface _Object; interface XXXXXXXX; };

  • Creating a System.Web.UI.Page programatically in IHTTPHandler

    - by ObiWanKenobi
    I am trying to use the ASP.NET (3.5) "Routing Module" functionality to create custom pages based on the contents of the URL. Various articles, such as this one: http://blogs.msdn.com/mikeormond/archive/2008/05/14/using-asp-net-routing-independent-of-mvc.aspx explain how to use ASP.NET Routing to branch to existing pages on the web server. What I would like to do is create the page on-the-fly using code. My first attempt looks like this: public class SimpleRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { string pageName = requestContext.RouteData.GetRequiredString("PageName"); Page myPage = new Page(); myPage.Response.Write("hello " + pageName); return myPage; } } But this throws an HTTPException saying "Response is not available in this context." at the Response.Write statement. Any ideas on how to proceed? UPDATE: In the end, I went with an approach based on IHttpModule, which turned out to be rather easy.

  • How can I make a DateTimePicker display an empty string?

    - by brass-kazoo
    I would like to be able to display a DateTimePicker that has a default value of nothing, i.e. no date. For example, I have a start date dtTaskStart and an end date dtTaskEnd for a task, but the end date is not known, and not populated initially. I have specified a custom format of yyyy-MM-dd for both controls. Setting the value to null, or an empty string at runtime causes an error, so how can I accomplish this? I have considered using a checkbox to control the enabling of this field, but there is still the issue of displaying an initial value.. Edit: Arguably a duplicate of the question DateTimePicker Null Value (.NET), but the solution I found for my problem is not a solution for that question, so I think it should remain here for others to find..

  • JTable.setRowHeight prevents me from adding more rows

    - by Brent Parker
    I'm working on a pretty simple Java app in order to learn more about JTables, TableModels, and custom cell renderers. The table is a simple table with 8 columns only with text in them. When you click on an "add" button, a dialog pops up and lets you enter the data for the columns. Now to my problem. One of the columns (the last one) should allow for multiple lines of text. I'm already putting HTML into the field, but it is not wrapping. I did some research and looked into JTable#setRowHeight(). However, once I use setRowHeight, I can no longer add rows to the table. The data is put into the table model, but it does not show in the table. If I remove the setRowHeight line, then it adds data just fine. Is there another step to adding data to my data model that I'm missing? Thanks a lot!

  • BindData to ITemplate for GridView in code behind

    - by tbischel
    How do I programmatically bind data to a custom item template column for a GridView? So far, I've done something similar to this: TemplateField foo = new TemplateField(); foo.ItemTemplate = new bar(); this.GridView1.Columns.Add(foo); where bar is like this: public class bar : ITemplate { public bar() { } public void InstantiateIn(Control container) { DropDownList ddl = new DropDownList(); container.Controls.Add(ddl); } } (the actual dropdownlist is populated) But ITemplate doesn't contain any kind of data binding properties to implement, and the TemplateField class doesn't seem to have any either... What do I do?

  • Create user variable in Intellij File Template

    - by Matt Broekhuis
    I am trying to use Intellij's file templates (not live templates) to help mitigate how much boilerplate code I use when making Services, daos, and their interfaces. I am able to use all the system defined variables just fine, such as ${PACKAGE_NAME} What I want though, is to be able to use my own variable names, like ${MY_USER_INPUT} however, when i do this like above, I get an error The documentation says : It is also possible to specify arbitrary number of custom variables in format ${<VARIABLE_NAME>}. and then Intellij is supposed to prompt the user for the value. However, this just plain doesn't work for me. What am I missing?

  • Drawbacks to using background-repeat only for colors?

    - by ineedtosleep
    So I need some custom colors on a layout, but I'm looking for a better way of doing it other than just slapping a giant picture with (background: url(something.jpg)) in the layout. Mostly I'm thinking of getting a color palette (i.e. from Adobe Kuler, colourlovers, etc.), getting a 5x5 sample of each color and sticking them in an array for CSS sprites or just as separate files and accessing them through: .color-one {transparent url(./one.gif) repeat} and just reusing that whenever I'd like to use the color. Are there any drawbacks to doing it this way? And if there are should I just stick with web-safe colors or is there a better way of doing this?

  • C# UserControl factory

    - by user1112111
    Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface). You want to display one of the controls in the odd days and the other in the even days. You also want to be able to drag&drop (Visual Studio) the UserControl on your form without knowing what the Control type will finally be. How do you do that ? Is the factory pattern useful here ?

  • Is there a good charting library for iPhone?

    - by Mike Akers
    I have a need to render and display charts (bar charts for now, but more types may be needed later) in an iPhone app I'm working on. I've done some looking around and it doesn't look like there are any really good, mature charting libraries for iPhone yet. I've also looked for something written for Cocoa on the Mac that can be adapted, but haven't found anything great yet. Anybody dealt with this before? Any recommendations? I did find Core Plot, but it seems to be in the early stages of development. Edit to add some details of requirements (as they currently stand ;) ) Bar Charts Horizontal bar charts Double stacked bar charts Axis labels (including rotated 90 degrees on the y axis) Labels above each bar on the chart Shaded or custom backgrounds

  • Mootools not loading fast enough IE6

    - by Tom
    Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites. This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent". If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain? Thanks Tom

  • Filtering by category in Magento 1.4

    - by Sam
    Hi All I have a custom module I made to show featured products on the homepage. I set it up to show products that are in a ‘featured’ category.

Anyone any ideas what might be up?

  • Cropping an image, saving output to a new file and get crop coordinates

    - by synic
    I'm interfacing with a service that allows you to upload an image, and also upload coordinates of a thumbnail of that image. I'm thinking that (if there isn't some sort of prefab Activity specifically for this) that I can use Android's crop utility. The only problem is that I can't overwrite the original file, the crop window needs to have a custom message (instead of "crop image"), and I'll need the coordinates of the crop. Is this possible? Is there another way to do this without writing my own Activity?

  • ResolveURL not resolving in a user control

    - by WebJunk
    I'm trying to use ResolveUrl() to set some paths in the code behind of a custom ASP.NET user control. The user control contains a navigation menu. I'm loading it on a page that's loading a master page. When I call ResolveUrl("~") in my user control it returns "~" instead of the root of the site. When I call it in a page I get the root path as expected. I've stepped through with the debugger and confirmed, ResolveUrl("~") returns "~" in my user control code behind. Is there some other way I should be calling the function in my user control code behind to get the root path of the site?

  • Link to audio in XHTML/EPUB

    - by wxs
    I'm looking into synchronizing an ebook in epub format (so the content is in XHTML) to an audio file. I'm thinking of putting something along the lines of: <a class="audiolink" href="sound.ogg?t=1093"></a> into the body of the document, and then have a custom epub reader that recognizes those tags and synchronizes the audio accordingly. That does seem like a bit of a hack to me though, especially the use of a special class name. Does anyone have any pointers to how this may be done in a more standards-compliant manner (or somewhere where it has been done before)? Ebooks with audio annotation seem like an idea that may already be out there.

  • Does Process.StartInfo.Arguments support a UTF-8 string?

    - by Patrick Klug
    Can you use a UTF-8 string as the Arguments for a StartInfo? I am trying to pass a UTF-8 (in this case a Japanese string) to an application as a console argument. Something like this (this is just an example! (cmd.exe would be a custom app)) var process = new System.Diagnostics.Process(); process.StartInfo.Arguments = "/K \"echo ????????\""; process.StartInfo.FileName = "cmd.exe"; process.StartInfo.UseShellExecute = true; process.Start(); process.WaitForExit(); Executing this seems to loose the UTF-8 string and all the target application sees is "echo ?????????" When executing this command directly on the command line (by pasting the arguments) the target application receives the string correctly even though the command line itself doesn't seem to display it correctly. Do I need to do anything special to enable UTF-8 support in the arguments or is this just not supported?

  • flex datagrid re-assign dataprovider

    - by gauravgr8
    Hi, I am working on a datagrid with custom itemRenderer & [Bindable]xmllist as dataprovider. Now the changes done in xmllist are not reflected on datagrid UI until unless I re-assign the dataprovider as the same xmllist. As the dataprovider is Bindable so re-assigning is not required. But it was not working so I re-assigned the xmllist to the dataprovider of datagrid. It worked. Now my problem is when I re-assign the dataprovider my datagrid flicker(refreshes). It should not happen. 1) Is there any way out to avoid re-assigning of dataprovider? 2) Is there any way to stop flickering of datagrid on re-assigning the dataprovider? Thanks in advance.

  • Basic refactoring features (e.g., Rename) unavailable when editing code in an aspx/ascx files

    - by DanM
    I was just editing some C# code between <% %> tags in an .ascx file, and I noticed that the Refactor contextual menu is unavailable. And even if I manually add items from this menu to a custom toolbar, they are disabled when viewing aspx/ascx files. I usually only have small snippets of C# code in my aspx/ascx files, but it would still be nice to be able to perform refactoring operations on any code that exists between <% %> tags. I feel like I'm going back to the dark ages when I have to use find/replace to change the name of a variable. Questions Is there a way to enable Visual Studio's refactoring features while viewing aspx/ascx files in Visual Studio? Are there any Visual Studio plug-ins (preferably free) that offer this kind of functionality?

  • What's the simplest way to ask for user input through Modal in Win Form

    - by Refracted Paladin
    What is the simplest way to implement a Modal(popup) MessageBox that allows a custom value to be entered and returned. In my case, a String. Maybe I am over thinking this but I figured I'd ask. I plan to just create a new Form. Add a label, a textbox, two buttons. Assign the textbox to a property and from my main form call a ShowDialog() on it. Will I be able to still access the property that way or should I somehow return the value? Is this a decent way of doing this?

  • NHibernate mapping one table on two classes with where selection

    - by Rene Schulte
    We would like to map a single table on two classes with NHibernate. The mapping has to be dynamically depending on the value of a column. Here's a simple example to make it a bit clearer: We have a table called Person with the columns id, Name and Sex. The data from this table should be mapped either on the class Male or on the class Female depending on the value of the column Sex. In Pseudocode: create instance of Male with data from table Person where Person.Sex = 'm'; create instance of Female with data from table Person where Person.Sex = 'f'; The benefit is we have strongly typed domain models and can later avoid switch statements. Is this possible with NHibernate or do we have to map the Person table into a flat Person class first? Then afterwards we would have to use a custom factory method that takes a flat Person instance and returns a Female or Male instance. Would be good if NHibernate (or another library) can handle this.

  • Default login popup for web sites

    - by John Quest
    Hi. I am trying to build a web site with ASP.NET MVC, I'm new to this. My question is: how can I display the default login dialog? I am not referring to a custom dialog, like the jQuery Dialog, there is a default pop-up for credentials, which looks different depending on browser, same as with javascript alert(), but I don't know how to display it. To know what I mean, go to http://fit.c2.com/wiki.cgi?WelcomeVisitors, there is a Login button at the bottom of the page, when you click it a pop-up appears. That is what I want to display. Any ideas?

  • Google Gadgets and external scripts

    - by Brandon Durham
    I'm trying to create my first custom Google Gadget to be used privately in my company's Google Sites intranet. Ideally I'd like to just show a thumbnail that the user can click that will open a modal window with the full video. This requires my including a couple of small JS libraries in my widget. For my widget I created this XML: <?xml version="1.0" encoding="UTF-8"?> <Module> <ModulePrefs title="Video Demos" /> <Content view="url" href="http://www.website.com/_gadgets/video.php"> </Content> </Module> The "video.php" page has simple HTML on it and includes two JS files for the modal window using but doesn't work. Are you not able to include external scripts like this? If not, what are my options here?
