  • Facebook with RestFB

    - by Trick
    I just began to use this and I already stumbled on some from-my-side-strange errors. I am using RestFB jar. My problem is, that I can not get my session key (this is the start of everything :)). FacebookClient facebookClient = new DefaultFacebookClient(API_KEY, SECRET_KEY); try { String token = facebookClient.execute("auth.createToken", String.class, Parameter.with("null", "null")); System.out.println(token); String session = facebookClient.execute("auth.getSession", String.class, Parameter.with("auth_token", token)); System.out.println(session); } catch (FacebookException e) { e.printStackTrace(); } I get the token correctly. Parameter.with("null,"null") is there because it demands at least one, but method for creating token doesn't expect any. When trying to get the session key, I get the following error: com.restfb.FacebookResponseStatusException: Received Facebook error response (code 100): Invalid parameter at com.restfb.DefaultFacebookClient.throwFacebookResponseStatusExceptionIfNecessary(DefaultFacebookClient.java:357) at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:320) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:188) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:178) Documentation for getting session doesn't say any more parameters are required! Did anybody already try this JAR or do you have any other solution for Java?

  • Resize and saving an image to disk in Monotouch

    - by Chris S
    I'm trying to resize an image loaded from disk - a JPG or PNG (I don't know the format when I load it) - and then save it back to disk. I've got the following code which I've tried to port from objective-c, however I've got stuck on the last parts. Original Objective-C. This may not be the best way of achieving what I want to do - any solution is fine for me. int width = 100; int height = 100; using (UIImage image = UIImage.FromFile(filePath)) { CGImage cgimage = image.CGImage; CGImageAlphaInfo alphaInfo = cgimage.AlphaInfo; if (alphaInfo == CGImageAlphaInfo.None) alphaInfo = CGImageAlphaInfo.NoneSkipLast; CGBitmapContext context = new CGBitmapContext(IntPtr.Zero, width, height, cgimage.BitsPerComponent, 4 * width, cgimage.ColorSpace, alphaInfo); context.DrawImage(new RectangleF(0, 0, width, height), cgimage); /* Not sure how to convert this part: CGImageRef ref = CGBitmapContextCreateImage(bitmap); UIImage* result = [UIImage imageWithCGImage:ref]; CGContextRelease(bitmap); // ok if NULL CGImageRelease(ref); */ }

  • Static IP for dynamic IP

    - by scape279
    I have a dynamic IP address. I would like to have a static IP, but Virgin Media don't allow static IPs for residential broadband services, even if you ask them really nicely and offer to pay for it without switching to a business tariff. I am already registered with a dynamic DNS service which is updated by my router eg me.example.com will always resolve to my dynamic IP. This is fine for some circumstances, but not if you can only enter an IP address into configuration files/hardware etc like firewalls, subversion services etc etc. Is there a way I can have a static IP address 'forwarding' to my dynamic IP? Would a possible solution involve tunnelling? Setting up a private proxy? Please note the following: I am able to buy an IP address from my web host. I have access to a webserver and I am able to create custom DNS zones. I'm happy to have a webserver running at home if necessary also. I do not wish to change broadband providers. I have zero control over the services that require the IP address entering so I cannot tackle the problem that way round (services I need to access are at work). PS I've tried googling this issue, but it is very difficult to search for as most results are related to dynamic dns (which I already have set up and isnt quite what I'm after)

  • Insert some data at later point once serialization(binary serialization) is done for a class

    - by coolcake
    My application is written in C# and I am a newbie to C#. I am facing with a problem during serialization. The problem is as follows. There are many classes in my project and when serialization is called on one of the main class object it serializes itself and during this process many of the member objects are also get serialized. This whole serialization is done in to a file with extension say ".bin". This bin file size should be of size max 20MB. In this process of serialization one of my other class also gets serialized to a stream, this class is having a big array. The size of this array or list can be of 80 MB or more. So during serialization i have serialize all the objects other than this array and depending upon the size left in the 20MB I need to add in between the serialization the number of array elements which can fit in the remaining memory. For the other array elements left out I have to create a similar kind of .bin file with all the objects serialized and in between need to insert the number of array elements that can fit there. The main problem here is the array elements get inserted at runtime and this list keeps on increasing. So i should be creating .bin files continuously until my application runs. Any ideas how can i implement a solution for this problem? Thanks in Advance.

  • Where does lucene .net cache the search results?

    - by Lanceomagnifico
    Hi, I'm trying to figure out where Lucene stores the cached query results, and how it's configured to do so - and how long it caches for. This is for an ASP.NET 3.5 solution. I'm getting this problem: If I run a search and sort the result by a particular product field, it seems to work the very first time each search and sort combination is used. If I then go in and change some product attributes, reindex and run the same search and sort, I get the products returned in the same order as the very first result. example Product A is named: foo Product B is named: bar For the first search, sort by name desc. This results in: Product A Product B Now mix up the data a bit: Change names to: Product A named: bar Product B named: foo reindex verify that the index contains the changes for these two products. search Result: Product A Product B Since I changed the alphabetical order of the names, I expected: Product B Product A So I think that Lucene is caching the search results. (Which, btw, is a very good thing.) I just need to know where/how to clear these results. I've tried deleting the index files and doing an IISreset to clear the memory, but it seems to have no effect. So I'm thinking there is another set of Lucene files outside of the indexes that Lucene uses for caching. EDIT I just found out that you must create the index for field you wish to sort on as un-tokenized. I had the field as tokenized, so sorting didn't work.

  • fmod VS2008 unresolved externals in dependant project

    - by Tom J Nowell
    Im currently trying to use the latest stable fmod ex in my project. I have a main executable in a project called engine4, and a project named DX9Platform in the solution as well which ti depends on. All the fmod code is in this DX9Platform project, which generates a lib file. DX9Platform includes fmodex_vc.lib and builds fine. However buildign Engien4 results in unresolved external symbol messages referencing files that use fmod in the DX9Platform project I have tried adding fmodex_vc.lib to the Engine4 project, with no success, how do I fix this?

  • Traversing/Manipulating new window from parent window with jquery

    - by Anthony
    I found a question already with a possible solution, but I had already tried the method suggested before reading it, and it even says it's inconsistent. So I guess I'm wondering why this doesn't work: $("img").click(function() { var imgwindow = window.open('imgwin.html','','width=460,height=345'); alert(imgwindow.find("img").attr("src")); }); The goal is to set the new window's img to the same src as the image that the user clicked to open the new window. But in the above scenario, I'm just trying to tap into the new window to get what it's already-set src. I have imgwin.html already written with a default src for the image, so it should alert that url. Instead I just get undefined. I also tried the following (which should be identical on the back end), but with the same results: $("img").click(function() { var imgwindow = window.open('imgwin.html','','width=460,height=345'); alert($("img",imgwindow).attr("src")); }); I even tried variations of wrapping the imgwindow variable in $() in case somehow jquery wasn't picking up on the variable as a DOM element. The only thing I can guess is that since window.open() is a method, jquery doesn't treat it like a DOM element, even though all documentation from basic javascript tutorials treat the variable as both a method to open the window and the pointer to the window's inner DOM.

  • How to best transfer large payloads of data using wsHttp with WCF with message security

    - by jpierson
    I have a case where I need to transfer large amounts of serialized object graphs (via NetDataContractSerializer) using WCF using wsHttp. I'm using message security and would like to continue to do so. Using this setup I would like to transfer serialized object graph which can sometimes approach around 300MB or so but when I try to do so I've started seeing a exception of type System.InsufficientMemoryException appear. After a little research it appears that by default in WCF that a result to a service call is contained within a single message by default which contains the serialized data and this data is buffered by default on the server until the whole message is completely written. Thus the memory exception is being caused by the fact that the server is running out of memory resources that it is allowed to allocate because that buffer is full. The two main recommendations that I've come across are to use streaming or chunking to solve this problem however it is not clear to me what that involves and whether either solution is possible with my current setup (wsHttp/NetDataContractSerializer/Message Security). So far I understand that to use streaming message security would not work because message encryption and decryption need to work on the whole set of data and not a partial message. Chunking however sounds like it might be possible however it is not clear to me how it would be done with the other constraints that I've listed. If anybody could offer some guidance on what solutions are available and how to go about implementing it I would greatly appreciate it. Related resources: Chunking Channel How to: Enable Streaming Large attachments over WCF Custom Message Encoder Another spotting of InsufficientMemoryException I'm also interested in any type of compression that could be done on this data but it looks like I would probably be best off doing this at the transport level once I can transition into .NET 4.0 so that the client will automatically support the gzip headers if I understand this properly.

  • jsf datatable lazy load filter and sorting

    - by darko petreski
    Hi, I have worked on several projects with a lot of data tables. The tables had sorting, filtering and paging of course on server side and with help of the db (all databases has implemented sording, filtering -where and limit the returned results). When workig on real application there are a thousands of even a millions rows. But I have seen several JSF dagatable components. They implement pagination, sorting and filtering on client side!! According to me this is very silly. This technology is called enterprise and they sort the data on the client side with java script! I have not seen any good JSF data grid that has build in features for sorting, filtering and lazy loading on the server side. Why is that? Am I looking in wrong direction or really there in no build support for this. Lately I am testing primefaces and lazy loading datatable. It really works fine, but the table i can only lazy load. If you add sort and filter then the problems begin. Conclusion: Is there any datatable JSF component than can perform lazy load pagination, and filtering and sorting on server side. If I need to implement my own solution thanks to the teams that made client side sorting and filtering, they are useless. Regards

  • Activity Indicator display in Table View whilst row data is being fetched

    - by Tofrizer
    Hi All, I am navigating from tableview1.row to a tableview2 which has a LOT of rows being fetched. Given the load time is around 3 seconds, I want the navigation to slide into tableview2 as soon as the tableview1.row is selected, and then display a UIActivityIndicatorView above tableview2 whilst the data is fetched and then rendered in its underlying table view. Note, tableview2 is actually a subview of the parent UIView (as opposed to the parent being a UITableView). I've seen this post: http://stackoverflow.com/questions/2153653/activity-indicator-shold-be-displayed-when-navigating-from-uitableview1-to-uitabl ... which gives instructions to add the activity indicator start and stopAnimating calls around the data fetch into viewDidLoad of tableview2. Thing is, I'm not sure how the above solution could work as viewDidLoad runs and completes before tableview2 visibly slides into view. Separately, I also tried adding an activity indicator over tableview2 in IB and added the IBOutlet indicator's start/stop animating code into viewDidAppear. What happens is the data fetch runs and I can see the indicator spinning but at the end of the fetch, the table view is empty. Seems like viewDidAppear is too late to add data to the table view as cellForRowAtIndexPath etc has already fired. Can anyone please suggest any pointers? I could very well be missing something obvious here (its nearly 5am where I am and think my brain is mush). Should I re-trigger cellForRowAtIndexPath etc from viewDidAppear? Is the issue that my table view is a subview and not the parent view? Thanks

  • Recover a folder or file in TortoiseSVN whilst also retaining all history.

    - by Topdown
    In revision 1 a folder existed. In revision 2 the folder was accidently deleted and the change committed. We wish to roll back such that the folder is present, and retain its history. In the TortoiseSVN docs it indicates 'how' in the section titled "Getting a deleted file or folder back". To quote: Getting a deleted file or folder back If you have deleted a file or a folder and already committed that delete operation to the repository, then a normal TortoiseSVN - Revert can't bring it back anymore. But the file or folder is not lost at all. If you know the revision the file or folder got deleted (if you don't, use the log dialog to find out) open the repository browser and switch to that revision. Then select the file or folder you deleted, right-click and select [Context Menu] - [Copy to...] as the target for that copy operation select the path to your working copy. A switch retrieves the file into my working copy as one would expect, however there is no "Copy to" option on the context menu when I right click this working copy. If I open the repos browser, there is a copy to option, but it seems this simply takes a copy of the file. The solution I feel is to do a Branch/Tag, but if I try this from a prior revision to the same path in the repository SVN throws error that the path already exists. Therefore, how do I recover a folder/file in TortoiseSVN whilst also retaining all history. TortoiseSVN v1.6.8, Build 19260 - 32 Bit , Subversion 1.6.11,

  • ASP.Net: Adding client side onClick to a HyperlinkField in GridView

    - by Nir
    I have an existing GridView which contains the field "partner name". It is sortable by partner name. Now I need to change the Partner Name field and in some condition make it clickable and alert() something. The existing code is: <asp:GridView ID="gridViewAdjustments" runat="server" AutoGenerateColumns="false" AllowSorting="True" OnSorting="gridView_Sorting" OnRowDataBound="OnRowDataBoundAdjustments" EnableViewState="true"> <asp:BoundField DataField="PartnerName" HeaderText="Name" SortExpression="PartnerName"/> I've added the column: <asp:hyperlinkfield datatextfield="PartnerName" SortExpression="PartnerName" headertext="Name" ItemStyle-CssClass="text2"/> which enables me to control the CSS and sort. However, I can't find how to add a client side javascript function to it. I found that adding : <asp:TemplateField HeaderText="Edit"> <ItemTemplate> <a id="lnk" runat="server">Edit</a> enable me to access "lnk" by id and add to its attributes. However, I lose the Sort ability. What's the correct solution in this case? Thanks.

  • Invalid length for a Base-64 char array.

    - by Code Sherpa
    As the title says, I am getting: Invalid length for a Base-64 char array. I have read about this problem on here and it seems that the suggestion is to store ViewState in SQL if it is large. I am using a wizard with a good deal of data collection so chances are my ViewSate is large. But, before I turn to the "store-in-DB" solution, maybe somebody can take a look and tell me if I have other options? I construct the email for delivery using the below method: public void SendEmailAddressVerificationEmail(string userName, string to) { string msg = "Please click on the link below or paste it into a browser to verify your email account.<BR><BR>" + "<a href=\"" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" + userName.Encrypt("verify") + "\">" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" + userName.Encrypt("verify") + "</a>"; SendEmail(to, "", "", "Account created! Email verification required.", msg); } The Encrypt method looks like this: public static string Encrypt(string clearText, string Password) { byte[] clearBytes = System.Text.Encoding.Unicode.GetBytes(clearText); PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); byte[] encryptedData = Encrypt(clearBytes, pdb.GetBytes(32), pdb.GetBytes(16)); return Convert.ToBase64String(encryptedData); } On the receiving end, the VerifyEmail.aspx.cs page has the line: string username = Cryptography.Decrypt(_webContext.UserNameToVerify, "verify"); And the decrypt method looks like: public static string Decrypt(string cipherText, string password) { **// THE ERROR IS THROWN HERE!!** byte[] cipherBytes = Convert.FromBase64String(cipherText); Can this error be remedied with a code fix or must I store ViewState in the database? Thanks in advance.

  • Database Change Management - Setup for Initial Create Scripts, Subsequent Migration Scripts

    - by Martin Aatmaa
    I've got a database change management workflow in place. It's based on SQL scripts (so, it's not a managed code-based solution). The basic setup looks like this: Initial/ Generate Initial Schema.sql Generate Initial Required Data.sql Generate Initial Test Data.sql Migration 0001_MigrationScriptForChangeOne.sql 0002_MigrationScriptForChangeTwo.sql ... The process to spin up a database is to then run all the Initlal scripts, and then run the sequential Migration scripts. A tool takes case of the versioning requirements, etc. My question is, in this kind of setup, is it useful to also maintain this: Current/ Stored Procedures/ dbo.MyStoredProcedureCreateScript.sql ... Tables/ dbo.MyTableCreateScript.sql ... ... By "this" I mean a directory of scripts (separated by object type) that represents the create scripts for spinning up the current/latest version of the database. For some reason, I really like the idea, but I can't concretely justify it's need. Am I missing something? The advantages would be: For dev and source control, we would have the same object-per-file setup that we're used to For deployment, we can spin up a new DB instance to the latest version either by running the Initial+Migrate, or by running the scripts from Current/ For dev, we do not need a DB instance running in order to do development. We can do "offline" development on the Current/ folder. The disadvantages would be: For each change, we need to update the scripts in the Current/ folder, as well as create a Migration script (in the Migration/ folder) Thanks in advance for any input!

  • WCF Manual SOAP POST using HttpWebRequest over https with Usertoken

    - by VonBlender
    Hi, I'm writing a client that calls a number of WCF webservices (written externallyt to my company) that are very similar in structure. The design I was hoping to use is to manually build the SOAP message from XML chunks that are stored in a database and then processed through a generic web service handler class. I have access to the WSDL's for each webservice and example working XML. The design approach is such that we can easily add to the message dynamically, hence the reason for not using the auto generated proxy classes I am basically at the last part now with the entire SOAP message constructed but am getting a SOAP fault security error returned. I have used fiddler to compare the message I'm sending with one that is sent using the normal (far simpler...) WCF generated proxy classes and can't see any difference apart from the id attribute of the Usertoken element in the SOAP header. This is where my lack of experience in this area isn't helping. I think this is because the id is generated automatically (presumably because we're using https). My question is how do I generate this programatically? I have searched for hours online but the majority of solutions are either using the proxy classes or not over https. I have briefly looked at WCE but aware this is replaced by WCF now so don't want to waste time looking into this if it's not the solution. Any help with this would be greatly appreciated. I can post some code examples when I'm back in work if it will help but the method I'm using is very straightforward and only using XElements and such like at the moment (as we're using linq to sql). thanks, Andy

  • Usinng svnadmin dump to revert the latest revision committed

    - by Wux
    What I need is that the latest (mistake) revision being reverted and that the repository does not store it in anyway. That is, I'm trying to erase the latest revision out of existence, NOT trying to fix things by coming back to the latest-1 revision. In other words, I want to avoid the repository growing in size. Suppose head revision is 100. I knew that the suggested answer is that svnadmin dump -r0:80 old-repo | svnadmin load --force-uuid new-repo. What I'm confusing myself about is why not svnadmin dump -r81:100 old-repo Why the first and not the second solution? I suppose svnadmin dump will erase the repository completely? And keeping only revision 0 - 80 in a dump file? Is my understanding of "taking a part out of the repository into a dump file" about svnadmin dump completely wrong? (That is revision 81 - 100 is still there) Sincere apologies if this has been asked. I did spend some time searching though no specific things about this were found. A topic link in case I miss it would be greatly appreciated.

  • InvalidOperationException (Lambda parameter not in scope) when trying to Compile a Lambda Expression

    - by Moshe Levi
    Hello, I'm writing an Expression Parser to make my API more refactor friendly and less error prone. basicaly, I want the user to write code like that: repository.Get(entity => entity.Id == 10); instead of: repository.Get<Entity>("Id", 10); Extracting the member name from the left side of the binary expression was straight forward. The problems began when I tried to extract the value from the right side of the expression. The above snippet demonstrates the simplest possible case which involves a constant value but it can be much more complex involving closures and what not. After playing with that for some time I gave up on trying to cover all the possible cases myself and decided to use the framework to do all the heavy lifting for me by compiling and executing the right side of the expression. the relevant part of the code looks like that: public static KeyValuePair<string, object> Parse<T>(Expression<Func<T, bool>> expression) { var binaryExpression = (BinaryExpression)expression.Body; string memberName = ParseMemberName(binaryExpression.Left); object value = ParseValue(binaryExpression.Right); return new KeyValuePair<string, object>(memberName, value); } private static object ParseValue(Expression expression) { Expression conversionExpression = Expression.Convert(expression, typeof(object)); var lambdaExpression = Expression.Lambda<Func<object>>(conversionExpression); Func<object> accessor = lambdaExpression.Compile(); return accessor(); } Now, I get an InvalidOperationException (Lambda parameter not in scope) in the Compile line. when I googled for the solution I came up with similar questions that involved building an expression by hand and not supplying all the pieces, or trying to rely on parameters having the same name and not the same reference. I don't think that this is the case here because I'm reusing the given expression. I would appreciate if someone will give me some pointers on this. Thank you.

  • Large Django application layout

    - by Rob Golding
    I am in a team developing a web-based university portal, which will be based on Django. We are still in the exploratory stages, and I am trying to find the best way to lay the project/development environment out. My initial idea is to develop the system as a Django "app", which contains sub-applications to separate out the different parts of the system. The reason I intended to make these "sub" applications is that they would not have any use outside the parent application whatsoever, so there would be little point in distributing them separately. We envisage that the portal will be installed in multiple locations (at different universities, for example) so the main app can be dropped into a number of Django projects to install it. We therefore have a different repository for each location's project, which is really just a settings.py file defining the installed portal applications, and a urls.py routing the urls to it. I have started to write some initial code, though, and I've come up against a problem. Some of the code that handles user authentication and profiles seems to be without a home. It doesn't conceptually belong in the portal application as it doesn't relate to the portal's functionality. It also, however, can't go in the project repository - as I would then be duplicating the code over each location's repository. If I then discovered a bug in this code, for example, I would have to manually replicate the fix over all of the location's project files. My idea for a fix is to make all the project repos a fork of a "master" location project, so that I can pull any changes from that master. I think this is messy though, and it means that I have one more repository to look after. I'm looking for a better way to achieve this project. Can anyone recommend a solution or a similar example I can take a look at? The problem seems to be that I am developing a Django project rather than just a Django application.

  • Creating a drop-down row in displaytag

    - by bphilipnyc
    I am currently using displaytag for tabular data, but would like to create a "kayak.com-like" interface where when a user clicks a row, the user is shown more details about the particular row without a page refresh. I tried using a decorator to return javascript that would do this. The javascript is executed, but it is only reflected in the column where it was rendered. I am looking to create a new row with the data. e.g.: public class CustomDecorator extends TableDecorator { public String getDetailsRow() { MyObject object = (MyObject)this.getCurrentRowObject(); return "<a onClick=\"myjsfunction(object.getId()); return true\">Details</a>"; } } ...and in the JSP I would have a detailsRow property nested between the display:table tags: <display:column property="detailsRow" sortable="false" /> Any tips on how to create a new row? The solution may be in the way that the javascript is written - I'm not an expert with Javascript, so any tips would be appreciated. Is there a better way to do this with displaytag? I don't know of any explicit integration that displaytag has with javascript (like an "onclick" parameter) either. This is my first question on stackoverflow, btw - so please let me know whether you need more detail.

  • How do I get a PHP class constructor to call its parent's parent's constructor

    I need to have a class constructor in PHP call its parent's parent's (grandparent?) constructor without calling the parent constructor. // main class that everything inherits class Grandpa { public function __construct() { } } class Papa extends Grandpa { public function __construct() { // call Grandpa's constructor parent::__construct(); } } class Kiddo extends Papa { public function __construct() { // THIS IS WHERE I NEED TO CALL GRANDPA'S // CONSTRUCTOR AND NOT PAPA'S } } I know this is a bizarre thing to do and I'm attempting to find a means that doesn't smell bad but nonetheless, I'm curious if it's possible. EDIT I thought I should post the rationale for the chosen answer. The reason being; it most elegant solutionto the problem of wanting to call the "grandparent's" constructor while retaining all the values. It's certainly not the best approach nor is it OOP friendly, but that's not what the question was asking. For anyone coming across this question at a later date - Please find another solution. I was able to find a much better approach that didn't wreak havoc on the class structure. So should you.

  • MySQL Connection Timeout Issue - Grails Application on Tomcat using Hibernate and ORM

    - by gav
    Hi Guys I have a small grails application running on Tomcat in Ubuntu on a VPS. I use MySql as my datastore and everything works fine unless I leave the application for more than half a day (8 hours?). I did some searching and apparently this is the default wait_timeout in mysql.cnf so after 8 hours the connection will die but Tomcat won't know so when the next user tries to view the site they will see the connection failure error. Refreshing the page will fix this but I want to get rid of the error altogether. For my version of MySql (5.0.75) I have only my.cnf and it doesn't contain such a parameter, In any case changing this parameter doesn't solve the problem. This Blog Post seems to be reporting a similar error but I still don't fully understand what I need to configure to get this fixed and also I am hoping that there is a simpler solution than another third party library. The machine I'm running on has 256MB ram and I'm trying to keep the number of programs/services running to a minimum. Is there something I can configure in Grails / Tomcat / MySql to get this to go away?

  • comparison between string literal

    - by wiso
    This very simple code: #include <iostream> using namespace std; void exec(char* option) { cout << "option is " << option << endl; if (option == "foo") cout << "option foo"; else if (option == "bar") cout << "opzion bar"; else cout << "???"; cout << endl; } int main() { char opt[] = "foo"; exec(opt); return 0; } generate two warning: comparison with string literal results in unspecified behaviour. Can you explain why exactly this code doesn't work, but if I change char opt[] to char *opt it works, but generates the warning? Is it related to the \0 termination? What is the difference between the two declaration of opt? What if I use const qualifier? The solution is to use std::string?

  • Need help regarding one LALR(1) parsing.

    - by AppleGrew
    I am trying to parse a context-free language, called Context Free Art. I have created its parser in Javascript using a YACC-like JS LALR(1) parser generator JSCC. Take the example of following CFA (Context Free Art) code. This code is a valid CFA. startshape A rule A { CIRCLE { s 1} } Notice the A and s in above. s is a command to scale the CIRCLE, but A is just a name of this rule. In the language's grammar I have set s as token SCALE and A comes under token STRING (I have a regular expression to match string and it is at the bottom of of all tokens). This works fine, but in the below case it breaks. startshape s rule s { CIRCLE { s 1} } This too is a perfectly valid code, but since my parser marks s after rule as SCALE token so it errors out saying that it was expecting STRING. Now my question is, if there is any way to re-write the production rules of the parser to account for this? The related production rule is:- rule: RULE STRING '{' buncha_replacements '}' [* rule(%2, 1) *] | RULE STRING RATIONAL '{' buncha_replacements '}' [* rule(%2, 1*%3) *] ; One simple solution I can think of is create a copy of above rule with STRING replaced by SCALE, but this is just one of the many similar rules which would need such fixing. Furthermore there are many other terminals which can get matched to STRING. So that means way too many rules!

  • Best way of storing an "array of records" at design-time

    - by smartins
    I have a set of data that I need to store at design-time to construct the contents of a group of components at run-time. Something like this: type TVulnerabilityData = record Vulnerability: TVulnerability; Name: string; Description: string; ErrorMessage: string; end; What's the best way of storing this data at design-time for later retrieval at run-time? I'll have about 20 records for which I know all the contents of each "record" but I'm stuck on what's the best way of storing the data. The only semi-elegant idea I've come up with is "construct" each record on the unit's initialization like this: var VulnerabilityData: array[Low(TVulnerability)..High(TVulnerability)] of TVulnerabilityData; .... initialization VulnerabilityData[0].Vulnerability := vVulnerability1; VulnerabilityData[0].Name := 'Name of Vulnerability1'; VulnerabilityData[0].Description := 'Description of Vulnerability1'; VulnerabilityData[0].ErrorMessage := 'Error Message of Vulnerability1'; VulnerabilityData[1]...... ..... VulnerabilityData[20]...... Is there a better and/or more elegant solution than this? Thanks for reading.
