  • Reading JSON with JQuery

    - by user70192
    Hello, I am using JQuery to execute an operation within a web service. After writing data back to my databaes, the service returns a JSON response. My request looks like the following: $.ajax({ url: "/services/myService.svc/PostMessage", type: "POST", contentType: "application/json; charset=utf-8", data: '{"message":"testing","comments":"test"}', dataType: "json", success: function (response) { if ((response.d != null) && (response.d.length > 0)) { // Parse the status code here } else { alert("error!"); } }, error: function (req, msg, obj) { alert("error: " + req.responseText); } }); When my response is returned, response.d contains the following: [{"StatusCode":1}] How do I parse out the value of the StatusCode?

    - by Cosmina
    I must read a file with a given name (it's caled "hamlet.txt"). The class used to read the file is defined like this #ifndef READWORDS_H #define READWORDS_H /** * ReadWords class. Provides mechanisms to read a text file, and return * capitalized words from that file. */ using namespace std; #include <string> #include <fstream> class ReadWords { public: /** * Constructor.

Any help please?

  • Reading what is in the vsdiagnostics blob in Azure (1.7)

    - by tomasmcguinness
    I've enabled Diagnostics in one of my Worker roles and published it to Azure. There was a new blob container created called "vsdiagnostics" and contained within in are two binary files. I'm assuming that these files contain the output of my Trace statements, but I'm unable to open these files as I have no idea what format they are in. I've not found anything on www.windowsazure.com about it and most of the tools they recommend are very outdated. I have installed Cerebrata's Azure Diagnostics Manager, but that isn't able to load the Trace Logs. If anyone could point me in the right direction I'd be grateful!

  • Reading from a database located in the Program Files folder using ODBC

    - by Dabblernl
    We have an application that stores its database files in a subfolder of the Program Files directory. These files are redirected to the VirtualStore in Vista and Windows 7. We represent data from the database using Microsoft DataReports (VB6). So far so good. But we now want to use Crystal Reports XI to represent data from the database. Our idea is to NOT pass this data to CR from our program, but to have CR retreive it from the database using a a system DSN through ODBC. In this way we hope to present our users with more flexibility in designing their own reports. What we do want to ensure though is that these system DSNs are configured correctly when the user installs our program or when the program calls the Crystal Report. Is there a smart way to do this using System variables for instance, instead of having to write a routine that checks for OS-version, whether UAC is enabled on the OS, whether the write restrictions on the Program Files folder have been lifted, etc and then adapts he System DSN to point to either the C:\Program Files\OurApp\Data folder, or the C:\Users\User\AppData\VirtualStore\Program Files\OurApp\Data folder? Suggestions for an entirely different approach are welcome too!

  • C# class design - expose variables for reading but not setting

    - by James Brauman
    I have a a polygon class which stores a list of Microsoft.Xna.Framework.Vector2 as the vertices of the polygon. Once the polygon is created, I'd like other classes to be able to read the position of the vertices, but not change them. I am currently exposing the vertices through this field: /// <summary> /// Gets the vertices stored for this polygon. /// </summary> public List<Vector2> Vertices { get { return _vertices; } } List<Vector2> _vertices; However you can change any vertex using code like: Polygon1.Vertices[0] = new Vector2(0, 0); or Polygon1.Vertices[0].X = 0; How can I limit other classes to be able to only read the properties of these vertices, and not be able to set a new one to my List? The only thing I can think of is to pass a copy to classes that request it. Note that Vector2 is a struct that is part of the XNA framework and I cannot change it. Thanks.

  • Reading a triangle of numbers into a 2d array of ints in Python

    - by Gabriel Silk
    I want to read a triangle of integer values from a file into a 2D array of ints using Python. The numbers would look like this: 75 95 64 17 47 82 18 35 87 10 20 04 82 47 65 ... The code I have so far is as follows: f = open('problem18.input', 'r') arr = [] for i in range(0, 15): arr.append([]) str = f.readline() a = str.split(' ') for tok in a: arr[i].append(int(tok[:2])) print arr I have a feeling this could be done in a tighter, more Pythonesque way. How would you do it?

  • Configuration file reading. Best practice

    - by Andrew Florko
    Application stores configuration data in custom section of configuration file. This information is used all over the application. Nowadays I use helper static class to to provide access like this (some code omitted or simplified): [XmlRoot("webSiteSection")] public class WebSiteConfig : IConfigurationSectionHandler { public static WebSiteConfig Current { get { if (_current == null) _current = (WebSiteConfig) ConfigurationManager.GetSection("webSiteSection"); return _current; } } [XmlElement("section1")] public Section1 Section1 { get; set; } [XmlElement("section2")] public Section2 Section2 { get; set; } ... public object Create(object parent, object configContext, XmlNode section) { var serializer = new XmlSerializer(typeof(WebSiteConfig)); return serializer.Deserialize(new XmlNodeReader(section)); } } Then I use it like this <%: WebSiteConfig.Current.Section1.Value1 %> <%: WebSiteConfig.Current.Section1.Value2 %> What do you think of it? I find it usable because it keeps code simple, but also confused as IConfigurationSectionHandler is deprecated since .NET Framework 2.0

  • JQuery - Fade in new Background Image?

    - by JasonS
    Hi, I think I may be trying something that isn't possible. I was recently tasked to create a html version of the flash site. On the flash site when you click on the body the image changes. I have done this with JQuery. Its brilliant! However.. it isn't "flash" enough. The powers that be want a fade effect between images. This is where I have come completely undone. This is how my script works at the moment. Images are stored in a div called photos. This is hidden. <div id="photos"> <img src="image.jpg" alt="Some caption" style="#page-bg-color" /> </div> When the page is loaded jquery checks to see if the first image is loaded. If it isn't then a loading symbol spins. When the image is loaded, it becomes the body background. $("body").css('background', 'url(' + photos[currentImage]["url"] + ') no-repeat 50% 50% fixed ' + photos[currentImage]["background"]); I have tried the following. I have tried animate. However, this doesn't work. I have tried this plugin: http://plugins.jquery.com/project/bgImageTransition This doesn't work either. It appears to clone the tag and do something. I assume it isn't working because you cannot clone the body tag. That or it is really old and is no longer compatible with the current version of JQuery. I fear that I have coded my way down a dead end. Does anybody know how I could make this work?

  • Drawing an image is completely out

    - by ct2k7
    Hi I'm using this code below to let a user "draw" their signature on a UIView component on my app: UIGraphicsBeginImageContext(signature.frame.size); [drawImage.image drawInRect:CGRectMake(0, 0, signature.frame.size.width, signature.frame.size.height)]; CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound); CGContextSetLineWidth(UIGraphicsGetCurrentContext(), 5.0); CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), 1.0, 0.0, 0.0, 1.0); CGContextMoveToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextAddLineToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextStrokePath(UIGraphicsGetCurrentContext()); CGContextFlush(UIGraphicsGetCurrentContext()); drawImage.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext() The issue I am having is that the drawing is not only is the drawing not in line with the pointer when in use in the simulator, the image is going outside of the designated UIView compontent and is getting smaller/out of focus the more I draw, as you can see in this image: And after a few lines, showing the boundaries of the exact are of where I can draw: Any ideas on what's happening here? lastPoint.y is defined as: lastPoint.y -= 20; Any ideas on what on earth is happening here?

  • Recommended reading for bioinformatics

    - by Matt
    I'm keen on learning about bioinformatics. I am ideally looking for a short course introduction, with some practical tasks I can get my teeth into immediately to see if there is any interest in it for me. I already have a good understanding of molecular biology, so I should be able to skip most of the foundational work. Any suggestions?

  • Reading same file from multiple threads in C#

    - by Gustavo Rubio
    Hi. I was googling for some advise about this and I found some links. The most obvious was this one but in the end what im wondering is how well my code is implemented. I have basically two classes. One is the Converter and the other is ConverterThread I create an instance of this Converter class that has a property ThreadNumber that tells me how many threads should be run at the same time (this is read from user) since this application will be used on multi-cpu systems (physically, like 8 cpu) so it is suppossed that this will speed up the import The Converter instance reads a file that can range from 100mb to 800mb and each line of this file is a tab-delimitted value record that is imported to another destination like a database. The ConverterThread class simply runs inside the thread (new Thread(ConverterThread.StartThread)) and has event notification so when its work is done it can notify the Converter class and then I can sum up the progress for all these threads and notify the user (in the GUI for example) about how many of these records have been imported and how many bytes have been read. It seems, however that I'm having some trouble because I get random errors about the file not being able to be read or that the sum of the progress (percentage) went above 100% which is not possible and I think that happens because threads are not being well managed and probably the information returned by the event is malformed (since it "travels" from one thread to another) Do you have any advise on better practices of implementation of threads so I can accomplish this? Thanks in advance.

  • Reading server error messages for a URLLoader

    - by Rudy
    Hello, I have an URL loader with the following code: public function getUploadURL():void { var request:URLRequest = new URLRequest(); var url:String = getPath(); // Adds time to prevent caching url += "&time=" + new Date().getTime(); request.url = url; request.method = URLRequestMethod.GET; _loader = new URLLoader(); _loader.dataFormat = URLLoaderDataFormat.TEXT; _loader.addEventListener(Event.COMPLETE, getBaseURL); _loader.addEventListener(IOErrorEvent.IO_ERROR, onGetUploadURLError); _loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, getHttpStatus); _loader.load(request); } My problem is that this request might be wrong, and so the server will give me a back a 400 Bad Request, with a message to explain the error. If the Event.COMPLETE, I can see some message (a response) back from the server in the "data" field of the Event, but if onGetUploadURLError or getHttpStatus is called, it just says that the error code is 400 but does not show me the message associated with it. The "data" field is undefined in getHttpStatus and it is "" in onGetUploadURLError. On the contrary, in getBaseURL, I get: {"ResponseMetadata":{...}} I checked and I do get a similar response in my browser for a wrong request, but I cannot see it. Any idea how I can please get the message? Thank you very much, Rudy

  • Reading a client's header from Python CGI script?

    - by jawonlee
    I'm writing a very simple web service, written in Python and run as CGI on an Apache server. According to Python docs (somewhere... I forgot where), I can use sys.stdin to read the data POSTed by a random client, and this has been working fine. However, I would like to be able to read the HTTP header information as well - incoming IP, user agent, and so on. I'd also like to keep it very simple for now, by using only Python libraries (so no mod-python). How do I do this?
