  • C++ Library API Design

    - by johannes
    I'm looking for a good resource for learning about good API design for C++ libraries, looking at shared objects/dlls etc. There are many resources on writing nice APIs, nice classes, templates and so on at source level, but barely anything about putting things together in shared libs and executables. Books like Large-Scale C++ Software Design by John Lakos are interesting but massively outdated. What I'm looking for is advice i.e. on handling templates. With templates in my API I often end up with library code in my executable (or other library) so if I fix a bug in there I can't simply roll out the new library but have to recompile and redistribute all clients of that code. (and yes, I know some solutions like trying to instantiate at least the most common versions inside the library etc.) I'm also looking for other caveats and things to mind for keeping binary compatibility while working on C++ libraries. Is there a good website or book on such things?

  • HG: fork web app project to separate API code from app code

    - by cs_brandt
    I have a web app thats been in active development for about 8 months now and its becoming apparent that the project has a need to maintain a separation between app specific code and our OO Javascript API. What I would like to do is have another repository with the following general structure of the js API code. repo_name | +---build | +---build_tools | +---doc | +---src | +---js Of course this structure is different from the original web app directory structure. If I make changes to this new repository how could I pull in those changes to the web app repository without unintentionally removing files or modifying the directory structure of the web app repository?

  • Unauthorized response from Server with API upload

    - by Ethan Shafer
    I'm writing a library in C# to help me develop a Windows application. The library uses the Ubuntu One API. I am able to authenticate and can even make requests to get the Quota (access to Account Admin API) and Volumes (so I know I have access to the Files API at least) Here's what I have as my Upload code: public static void UploadFile(string filename, string filepath) { FileStream file = File.OpenRead(filepath); byte[] bytes = new byte[file.Length]; file.Read(bytes, 0, (int)file.Length); RestClient client = UbuntuOneClients.FilesClient(); RestRequest request = UbuntuOneRequests.BaseRequest(Method.PUT); request.Resource = "/content/~/Ubuntu One/" + filename; request.AddHeader("Content-Length", bytes.Length.ToString()); request.AddParameter("body", bytes, ParameterType.RequestBody); client.ExecuteAsync(request, webResponse => UploadComplete(webResponse)); } Every time I send the request I get an "Unauthorized" response from the server. For now the "/content/~/Ubuntu One/" is hardcoded, but I checked and it is the location of my root volume. Is there anything that I'm missing? UbuntuOneClients.FilesClient() starts the url with "https://files.one.ubuntu.com" UbuntuOneRequests.BaseRequest(Method.{}) is the same requests that I use to send my Quota and Volumes requests, basically just provides all of the parameters needed to authenticate. EDIT:: Here's the BaseRequest() method: public static RestRequest BaseRequest(Method method) { RestRequest request = new RestRequest(method); request.OnBeforeDeserialization = resp => { resp.ContentType = "application/json"; }; request.AddParameter("realm", ""); request.AddParameter("oauth_version", "1.0"); request.AddParameter("oauth_nonce", Guid.NewGuid().ToString()); request.AddParameter("oauth_timestamp", DateTime.Now.ToString()); request.AddParameter("oauth_consumer_key", UbuntuOneRefreshInfo.UbuntuOneInfo.ConsumerKey); request.AddParameter("oauth_token", UbuntuOneRefreshInfo.UbuntuOneInfo.Token); request.AddParameter("oauth_signature_method", "PLAINTEXT"); request.AddParameter("oauth_signature", UbuntuOneRefreshInfo.UbuntuOneInfo.Signature); //request.AddParameter("method", method.ToString()); return request; } and the FilesClient() method: public static RestClient FilesClient() { return (new RestClient("https://files.one.ubuntu.com")); }

  • Exposing API through a DLL

    - by MageNewbie
    I have a C++ application; I would like to expose an API from that application allowing me to control the C++ app from a VB6 app. I want to expose the API through a DLL file. Is this a viable option (is it possible) ? I haven’t been able to find any literature on using DLLs in this way. In fact from what I have read it seems like this is not possible because DLLs create their own new instance for every application they are linked in. If you have meet theses requirements in an application you built or if your knowledgeable on the subject, please give me a push in the right direction.

Its will the easiest way to get a free php api for that I think, and try too edit some code. But I did not found anything.

  • Returning Images from ASP.NET Web API

    - by bipinjoshi
    Sometimes you need to save and retrieve image data in SQL Server as a part of Web API functionality. A common approach is to save images as physical image files on the web server and then store the image URL in a SQL Server database. However, at times you need to store image data directly into a SQL Server database rather than the image URL. While dealing with the later scenario you need to read images from a database and then return this image data from your Web API. This article shows the steps involved in this process. http://www.bipinjoshi.net/articles/4b9922c3-0982-4e8f-812c-488ff4dbd507.aspx

  • low level api or graphics library?

    - by German
    Well, I want to learn game development, I've already know a little bit about xna, ogre and DX but, I want to choose one of them and stick with it. I'm not trying to make a "directx vs xna, ogre vs opengl, etc." thread. Some people told me that it's better to learn an engine like Ogre because you can develop games directly and you don't have to worry about the low level details, I know that. Other people told me that it's better to learn a low level api before learning something like Ogre because you will able to understand how it works. Is it valuable to have experience with Ogre or another engine but don't know anything about a low level api? What do you recommend me? Thanks in advance.

  • design practice for business layer when supporting API versioning

    - by user1186065
    Is there any design pattern or practice recommended for business layer when dealing with multiple API version. For example, I have something like this. http://site.com/blogs/v1/?count=10 which calls business object method GetAllBlogs(int count) to get information http://site.com/blogs/v2/?blog_count=20 which calls business object method GetAllBlogs_v2(int blogCounts) Since parameter name is changed, I created another business method for version 2. This is just one example but it could have other breaking changes for which it requires me to create another method to support both version. Is there any design pattern or best practice for business/data access layer I should follow when supporting API Versioning?

  • Recomendation for Webshop with API

    - by m.sr
    I'm searching for a webshop. The problem with my search is, that the webshop-software of my choice needs to have a useabel API or some interface for external applications. E.g. i need to place orders by an external application or need to get product descriptions or warehouse stock from the external application. I somehow would like to have a webshop wehere the webinterface is just one way to interact with the whole system. There are some other requirments, which have to be fullfilled, but i guess they are kind of common: running on linux MySQL (we already have MySQL-replication and backup in place) i like open source but i'm willing to pay for it, if it's worth it I found some webshops on the net - but perhaps you can tell me, if theres any hope for a webshop with a good API before i go and test all of them, on the first look i didn't find any docs about any interface to external applications for any of my search results. Thank you!

  • Is it possible to build a single game to run in Facebook & Google+?

    - by Songo
    I was asked by my customer to build a Facebook game. The game would be something similar to Mafiawars.com where the game is hosted on a server and run through a frame on Facebook. The thing is after several days of negotiations with the customer and near the finalization of the requirements he mentioned something strange. He said that if the game was successful on Facebook then we may add it to Google+ too. I thought he meant that we'll develop a new version for Google+, but he refused as he argued that the game should be able to support both sites and he won't pay for the same game twice. Now I haven't developed neither Facebook nor Google+ games before, so I don't know if it is possible to build a single Facebook/Google+ game. How would you react to such requirement? How would you design such an application? Notes I confirmed with the customer that he wasn't talking about using Open ID he wanted full integration (sharing post, friend requests,..etc.) I really don't want to lose that customer for numerous reasons (He even agreed to extend the project time to compensate for the time I need to learn Facebook/Google+ APIs)

  • Does Google Analytics exclude Campaign traffic from Facebook in the Social reports?

    - by user1612223
    For a while we have used campaign tags when putting posts on Facebook so that we can run campaign reports in Google analytics on those links. However it appears that traffic from those links are being excluded in Google's Social reports. For example between 7/20 and 8/19 I'm seeing 123 Visits where Facebook is the source in my Campaigns report, but only 29 Visits where Facebook is the source in my Social Sources report. Main questions: Does Google exclude campaign traffic from it's social reports? If it does, is there any way to reconcile that so that the traffic shows up in both reports? If it doesn't, what could be causing the vast discrepancy? One observer noted that we are setting the Medium to "Post" when passing the campaign parameters, and that Google may only allow "Referral" traffic in it's social reports (Just speculation). In that case we could potentially change the Medium to "Referral", but that would undermine some of our strategy in being able to set different mediums. I have also considered that maybe the campaign traffic came to the site several times, and the social report may count the same user as less visits, however over 70% of the Facebook campaign traffic is new traffic, so at a minimum there would need to be over 85 Visits on the Social side for that argument to be valid. I've done several searches for any information on this topic, and haven't run across much of anything. I did post the same question on Google's Product Forum and have not gotten a response. The title of that question was 'Facebook Campaign Traffic Not Showing in Social Reports'. The inability to pass campaign data on Facebook posts would make evaluating the performance of those specific posts very difficult, so I'm hoping there is a solution to this.

  • Embed custom font in Actionscript 3 project

    - by Jan
    I want to display "Hello World" with calibri.ttf using only AC3. How would I do that? Found two solutions on the web but I cannot use any of them - The Adobe documentation site requires the use of Flash CS4. (Don't know how to use this in Flex Builder) - The embed tag method requires FLEX SDK Is it possible to embed font with purely Actionscript 3 in an actionscript project using Flex Builder?

  • translating Ecmascript (Java,javascript,Actionscript) knowledge to Objective C

    - by eco_bach
    Hi Newcomer to Objective C and trying to translate concepts and sytax I know from ecmascript based languages to Objective C. Is it proper to think of the .h header file in ObjectiveC as an Interface in Actionscript? Lets take the following code example in Objective C which calls a method containing 2 arguments [myTextObject setString: @"Hello World" color: kWhiteColor]; In Actionscript(or javascript) would this be the same as calling 2 accessor methods on 'myTextObject'? ie myTextObject.setString("Hello World") myTextObject.color(kWhiteColor);

  • Why does Facebook iOS dialog for feed publish disappear after login?

    - by Mason G. Zhwiti
    I'm trying to use the Facebook iOS "feed" dialog call to allow my app's user to share something on their Facebook wall. When the facebook app is not installed, it attempts to let them authenticate within the app (presumably using a web view). The issue is that this dialog just disappears once they authenticate. I was expecting the web view to return to the "feed" sharing view. How do I detect that they authenticated so that I can re-open the feed dialog? I've added fbDidLogin to my app delegate, but it's not being called. (I wasn't sure if this would normally be called or not, but I read several people recommending this.) SBJSON *jsonWriter = [SBJSON new]; // The action links to be shown with the post in the feed NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: @"More Videos",@"name",@"http://www.example.com/",@"link", nil], nil]; NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"Test Caption", @"caption", @"Test Description", @"description", @"https://s3.amazonaws.com/example/images/test.png", @"source", self.video.blogLink, @"link", @"01234567890123", @"app_id", actionLinksStr, @"actions", nil]; [delegate facebook].sessionDelegate = delegate; [[delegate facebook] dialog:@"feed" andParams:params andDelegate:self];

  • How to receive userinfo with google adwords api libraries

    - by PatrickvKleef
    I'm using the Google Adwords API libraries and I would like to receive the userinfo of the logged in user. I added the userinfo scope as followed: googleAdwordsUser = new AdWordsUser(); string oauth_callback_url = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path); googleAdwordsUser.OAuthProvider = new AdsOAuthNetProvider("https://adwords-sandbox.google.com/api/adwords/ https://www.googleapis.com/auth/userinfo.email", oauth_callback_url, Session.SessionID); When the callback url is called, I'm trying to get the users emailaddress, but it isn't working, the error 'The remote server returned an error: (401) Unauthorized.' is thrown. string url = @"https://www.googleapis.com/oauth2/v2/userinfo?access_token=" + token; HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url); objRequest.Method = "GET"; HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse(); string result = string.Empty; using (StreamReader sr = new StreamReader(objResponse.GetResponseStream())) { result = sr.ReadToEnd(); } Does somebody knows how to fix this? Thanks.

  • Restoring a "Canceled" event with Google Calendar API?

    - by user283182
    I'm trying to change the status of an event back from "canceled" to "confirmed" using Google Calendar API (I'm using .NET but an answer in any language would help) but I get GDataRequestException error: "You can't modify a cancelled event" If I've used the API to delete an event in a repeating series, for example, is it possible to change the status of the resulting recurrence exception (there's no EXDATE, just a new "canceled" event that is only visible when the feed is requested with start and end date) to "confirmed" (or even delete the resulting exception completely) in order to restore the repeating series to the original state? event.Delete() and event.Update() don't even see the event any longer once it's been .canceled. event.Update() gives the above error. Thanks!

  • Limit the model data fields serialized by Web API based on the return type Interface

    - by Stevo3000
    We're updating our architecture to use a single object model for desktop, web and mobile that can be used in the MVVM pattern. I would like to be able to limit the data fields that are serialized through Web API by using interfaces on the controllers. This is required because the model objects for mobile are stored in HTML5 local storage so don't carry optional data while a thin desktop client would be able to store (and work with) more data. To achieve this a model will implement the different interfaces that define which data fields should be serialized and there will be a controller specific to the interface. The problem is that the Web API always serializes every field in the model even if it is not part of the interface being returned. How can we only serialize fields in the returned interface?

  • How to get the Facebook iFrame Tab url (including parameters) from within the app?

    - by martincarlin87
    I think there are a few similar questions that seem to suggest using app_data in the signed request (http://developers.facebook.com/docs/authentication/signed_request/) but I'm not sure if it will be possible to do what I am trying to achieve with it as I've never used it before. If I have my Facebook 'Tab' Url as follows: http://www.facebook.com/pages/PAGE_TITLE/PAGE_ID?sk=app_APP_ID What I want to do is add an extra parameter on the end as follows: &WT.mc_id=email-uk-8014 The reason for this is for tracking purposes and links will be sent out of the form http://www.facebook.com/pages/PAGE_TITLE/PAGE_ID?sk=app_APP_ID&WT.mc_id=email-uk-8014 and the extra parameter will allow us to track the campaign id. As you can see I have no way of knowing the value of the parameter beforehand as it depends on the link clicked by the user so is it possible to somehow get the value of the WT.mc_id parameter inside my iframe app?

  • Facebook page: How to add a customized box at the bottom left side of wall tab?

    - by Unreality
    Dear all, I have a question about Facebook Page: (NOT user profile page, I mean a facebook page where you can become a fan) How to add a customized box at the bottom left side of wall tab? (I am the page creator/admin) Please don't just give an answer "add the box to the page". Cause I really don't know how. Also, it seems that putting $facebook-api_client-profile_setFBML and $facebook-api_client-profile_setInfo for the application won't provide a way for the page to add the box. Below is an example image that is done by the other. I have circled the box at the image. I would like to know how to do the same to the page that I owned. Many thanks for reading.
