• importing modules in app engine

  - by tanky

  Ive asked this before, but it seems i wasnt clear/detailed enough and after a week of trying im still struggling so i will try again. i am trying to use, oauth2 and ply on app engine. i have tried copying their directories into my app engine project directory (in the form ply-3.4 or brosner-python-oauth2-82a05f9) and i have tried copying the specific sub directory contained within the aforemention one. (ply or oauth2) i have tried saying import oauth2, from brosner-oauth2_python-82a05f9 import oauth and other variations on the theme, but i still cant get it to work nothing has worked. i have tried including them in app.yaml, but that seemed to create an even bigger error as my entire project wouldnt even run when i tried that. and now i have run out of things to try. the error log i am getting is as follows.

• waiting for 2 different events in a single thread

  - by João Portela

  component A (in C++) - is blocked waiting for alarm signals (not relevant) and IO signals (1 udp socket). has one handler for each of these. component B (java) - has to receive the same information the component A udp socket receives. periodicaly gives instructions that should be sent through component A udp socket. How to join both components? it is strongly desirable that: the changes to attach component B to component A are minimal (its not my code and it is not very pleasent to mess with). the time taken by the new operations (usually communicating with component B) interfere very little with the usual processing time of component A - this means that if the operations are going to take a "some" time I would rather use a thread or something to do them. note: since component A receives udp packets more frequently that it has component B instructions to forward, if necessary, it can only forward the instructions (when available) from the IO handler. my initial ideia was to develop a component C (in C++) that would sit inside the component A code (is this called an adapter?) that when instanciated starts the java process and makes the necessary connections (that not so little overhead in the initialization is not a problem). It would have 2 stacks, one for the data to give component B (lets call it Bstack) and for the data to give component A (lets call it Astack). It would sit on its thread (lets call it new-thread) waiting for data to be available in Bstack to send it over udp, and listen on the udp socket to put data on the Astack. This means that the changes to component A are only: when it receives a new UDP packet put it on the Bstack, and if there is something on the Astack sent it over its UDP socket (I decided for this because this socket would only be used in the main thread). One of the problems is that I don't know how to wait for both of these events at the same time using only one thread. so my questions are: Do I really need to use the main thread to send the data over component A socket or can I do it from the new-thread? (I think the answer is no, but I'm not sure about race conditions on sockets) how to I wait for both events? boost::condition_variable or something similar seems the solution in the case of the stack and boost::asio::io_service io_service.run() seems like the thing to use for the socket. Is there any other alternative solution for this problem that I'm not aware of? Thanks for reading this long text but I really wanted you to understand the problem.

• How do I send user to a URI on MouseLeftButtonUp?

  This question is for Windows Phone 7. I'd like to send the user to a specific external URI when the entire ListBox item is clicked (not HyperLinkButton). I already have a MouseLeftButtonUp event handler for the item. At this point, I can't find a way to navigate the user to the URI.

• Server.Execute - render .ASP from MVC controller action

  - by David Lively

  I need to render an ASP page to a string from an MVC controller action. I can use Server.Execute() to render a .aspx page, but not a .asp page. Here's what I'm using: public ActionResult Index() { Server.Execute("/default.asp"); return new EmptyResult(); } which returns `No http handler was found for request type 'GET'` Any suggestions? I can do something similar with with a web request, but I'd rather avoid the overhead of a loopback request.

• How to get the form active control?

  - by PabloG

  Is there a way to get the form active control? I was checking in the help for the "Support.GetActiveControl" method but it isn't supported :) for the Compact Framework. I suppose that I can track the focus by adding a custom GotFocus event handler to all the form controls, but I'm looking for a more generic way that can be implemented for any form.

• How to give focus to default program of shell-opened file, from Java ?

  - by Rabarberski

  From within Java, I am opening an Excel file with the default file handler (MS Excel, in this case :-) ) using the method described in this stackoverflow question: Desktop dt = Desktop.getDesktop(); dt.open(new File(filename)); However, the Excel program doesn't get the focus. Is there any easy way to do so? Edit: There is a related stackoverflow question for C#, but I didn't find any similar Java method.

• ReSharper conventions for names of event handlers.

  - by Belousov Pavel

  Hello, When I add new event handler for any event, VS creates method like Button_Click. But ReSharper underlines this method as Warning, because all methods should not have any delimeters such as "_". How can I customize rules of ReSharper so that it doesn't underline such methods? Or may be I should rename such methods? Thanks in advance.

• How not to abort http response c#

  - by user194076

  I need to run several methods after sending file to a user for a download. What happens is that after I send a file to a user, response is aborted and I can no longer do anything after response.end(). for example, this is my sample code: Response.Clear(); Response.AddHeader("content-disposition", "attachment; filename=test.pdf"); Response.ContentType = "application/pdf"; byte[] a = System.Text.Encoding.UTF8.GetBytes("test"); Response.BinaryWrite(a); Response.End(); StartNextMethod(); Response.Redirect(URL); So, in this example StartNextMethod and Response.Redirect are not executing. What I tried is I created a separate handler(ashx) with the following code: public void ProcessRequest(HttpContext context) { context.Response.Clear(); context.Response.AddHeader("content-disposition", "attachment; filename=test.pdf"); context.Response.ContentType = "application/pdf"; byte[] a = System.Text.Encoding.UTF8.GetBytes("test"); context.Response.BinaryWrite(a); context.Response.End(); } and call it like this: Download d = new Download(); d.ProcessRequest(HttpContext.Current); StartNextMethod(); Response.Redirect(URL); but the same error happen. I've tryied to replace Response.End with CompleteRequest but it doesn't help. I guess the problem is that I'm using HttpContext.Current but should use a separate response stream. Is that correct? how do I do that in a separate method generically (Assume that I want my handler to accept byte array of data and content type and be downloadable from a separate response. I really do not want to use a separate page for a response. UPDATE I still didn't find a good solution. I'd like to do some actions after user has downloaded a file, but without using a separate page for a response\request thing.

  I'm working on an ASP.NET app where I'm in need of jQuery AutoComplete.

• What's the Microsoft Ajax equivalent to jquery.ajaxSetup() or .ajaxError()?

  - by Seth Petry-Johnson

  I have an ASP.NET MVC site that uses both Microsoft Ajax [Ajax.BeginForm()] and jQuery to make asynchronous requests. I want to configure both frameworks such that a generic error handler is automatically attached if the developer does not explicitly specify a failure callback. In jQuery I can accomplish this with either .ajaxSetup() or .ajaxError(). What is the equivalent in the Microsoft Ajax client library? I'm fairly sure it's something in the Sys object but I can't find it...

• Blit Queue Optimization Algorithm

  - by martona

  I'm looking to implement a module that manages a blit queue. There's a single surface, and portions of this surface (bounded by rectangles) are copied to elsewhere within the surface: add_blt(rect src, point dst); There can be any number of operations posted, in order, to the queue. Eventually the user of the queue will stop posting blits, and ask for an optimal set of operations to actually perform on the surface. The task of the module is to ensure that no pixel is copied unnecessarily. This gets tricky because of overlaps of course. A blit could re-blit a previously copied pixel. Ideally blit operations would be subdivided in the optimization phase in such a way that every block goes to its final place with a single operation. It's tricky but not impossible to put this together. I'm just trying to not reinvent the wheel. I looked around on the 'net, and the only thing I found was the SDL_BlitPool Library which assumes that the source surface differs from the destination. It also does a lot of grunt work, seemingly unnecessarily: regions and similar building blocks are a given. I'm looking for something higher-level. Of course, I'm not going to look a gift horse in the mouth, and I also don't mind doing actual work... If someone can come forward with a basic idea that makes this problem seem less complex than it does right now, that'd be awesome too. EDIT: Thinking about aaronasterling's answer... could this work? Implement customized region handler code that can maintain metadata for every rectangle it contains. When the region handler splits up a rectangle, it will automatically associate the metadata of this rectangle with the resulting sub-rectangles. When the optimization run starts, create an empty region handled by the above customized code, call this the master region Iterate through the blt queue, and for every entry: Let srcrect be the source rectangle for the blt beng examined Get the intersection of srcrect and master region into temp region Remove temp region from master region, so master region no longer covers temp region Promote srcrect to a region (srcrgn) and subtract temp region from it Offset temp region and srcrgn with the vector of the current blt: their union will cover the destination area of the current blt Add to master region all rects in temp region, retaining the original source metadata (step one of adding the current blt to the master region) Add to master region all rects in srcrgn, adding the source information for the current blt (step two of adding the current blt to the master region) Optimize master region by checking if adjacent sub-rectangles that are merge candidates have the same metadata. Two sub-rectangles are merge candidates if (r1.x1 == r2.x1 && r1.x2 == r2.x2) | (r1.y1 == r2.y1 && r1.y2 == r2.y2). If yes, combine them. Enumerate master region's sub-rectangles. Every rectangle returned is an optimized blt operation destination. The associated metadata is the blt operation`s source.
