  • how does fgets internally works?

    - by Registered User
    Well it is a basic question but I seem confused enough. #include<stdio.h> int main() { char a[100]; printf("Enter a string\n"); scanf("%s",a); } Basically the above is what I want to achieve. If I enter a string James Bond then I want that to be stored in array a. But the problem is because of presence of a blank space in between only James word is stored. So how can I solve this one. UPDATE After the replies given below I understand fgets() would be a better choice. I want to know internal working of fgets as why is it able to store the string with space where as scanf is not able to do the same.

  • Using svn with xampp for php projects

    - by idrish
    I have heard a lot about version control and would like to work on it. I read some tutorials about the same. However i am not quite sure how svn works with xampp. I have installed svn, Tortoise svn and made the necessary changes in xampp. For instance i copied the two required modules to c:/xampp/apache/modules and also made changes to the conf file in apache. Here are the changes made in c:/xampp/apache/conf/httpd.conf. # Configure Subversion repository <Location /svn> DAV svn SVNPath “C:\svn” AuthType Basic AuthName “Subversion repository” AuthUserFile “c:\svn_conf\passwd” Require valid-user </Location>t I created the repository at c:/svn and also created the password file. However when i visit http:/localhost/svn i get a 404 page not found error. Where am i going wrong. what am i missing.? Any pointers?? Thanks in advance.

  • How do I convert a windows forms app from C# to VB ?

    - by SLC
    I've been converting all kinds of other things, classes, interfaces, ASP.NET MVC apps, and WPF applications, but I am stumped as to how to convert a windows forms application, as the whole structure seems to be different. Does anyone have any advice on how to tackle this problem? I see essentially that you have two files, Form1.cs and Form1.Designer.cs. Literally translating them from C# to VB doesn't work because of some intricacies or other of how Visual Basic works. I think you /might/ be able to convert Form1.cs in this way, as it's just a constructor plus event handlers, but the designer contains the references to the controls etc. and I am not sure how to go about doing that. I am using Visual Studio 2010 Beta 2.

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • Mysql query different group by

    - by solomongaby
    Hello i have a products table that contains normal products and configurable product It has a basic stucture of: id name price configurable ('yes', 'no') id_configuration Normal products have configurable no and 0 as id configuration, and configurable products have it set to yes and have the same id_configuration value. The current query is: SELECT `products`.* FROM `products`, `categories`, `product_categories` WHERE `categories`.`id` = 23 AND `products`.`id` = `product_categories`.`id_product` AND `categories`.`id` = `product_categories`.`id_category` AND `products`.`active` = 'yes' AND ORDER BY `pos_new` ASC, `created` DESC LIMIT 0,20 I was wondering if there is a way to group by id_configuration, but only for the configurable products. The reason is that i want only one of the configuration products to show in search. I was thinking i could do a join, but was wondering if there is a way to do some kind of special group by. For example for configurable yes the field should be id_configuration otherwise it should be the id field Thanks a lot for any sugestions

  • Delegate methods of NSTextField using NSNotification

    - by hekevintran
    I have an NSTokenField in a window. I am using it to store tags related to a Core Data object. Right now I have it set up such that I can add tags to the objects, but I cannot delete them. I need a delegate method on the NSTokenField that can let me know when the user has moved the focus out of the NSTokenField. Since NSTokenField is a subclass of NSTextField I figured that I could use its delegate methods. It has two that I think could be useful: - (void)textDidChange:(NSNotification *)aNotification - (void)textDidEndEditing:(NSNotification *)aNotification I set my controller class as the delegate of my NSTokenField and put both of these methods into my controller class. I put a basic NSLog into each of them and neither is triggered when I interact with the NSTokenField. I am guessing it has something to do with NSNotification. How do I activate these methods?

  • Do you have any tips for comments to keep them in step with the code? [closed]

    - by Rob Wells
    Possible Duplicate: How do you like your comments? G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code. My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?" Edit: Oops. Seems to be a duplicate of this question http://stackoverflow.com/questions/121945/how-do-you-like-your-comments so sorry for the noise. Thanks to my, seemingly, SO shadow for pointing it out - wouldn't have thought I was that interesting. Now off to read the original post and see if it is relevant. Edit: I meant to emphasise the best appraoch to ensure that your comments will stay in step with the code. Maybe expressing an intent rather than the mechansim for instance.

  • Perl Regex Output only characters that can be used as unix filename

    - by Jeff Balinsky
    I wrote a basic mp3 organizing script for myself. I know the power of regex but I suck with the syntax I have the line $outname = "/home/jebsky/safehouse/music/mp3/" . $inital . "/" . $artist . "/" . $year ." - ". $album . "/" . $track ." - ". $artist ." - ". $title . ".mp3"; All I want is a regex to change $outname so that any non safe for filename characters get replaced by an underscore Thanks Jeff

  • Can I use the newer versions of Visual Studio to do "old" things?

    - by Ptah- Opener of the Mouth
    I have several ATL/COM-based DLLs that I've been using Visual C++ 6.0 on. I require a couple of "old" things out of the generated DLLs: (1) They must be compatible with projects developed in Visual Basic 6.0 (the old VB6, emphatically not VB.Net). (2) They must be compatible with old operating systems - minimum Windows 98 SE. To be clear, I mean they must run on such OSes, not that I would have to be able to develop them on a machine running such an OS. I am sick of Visual Studio 6.0. Converting to Dot Net (or any other major change like that) is out of the question at the current time, so I must continue to use VB6. But can I switch to the newer Visual Studio's C++, with a minimum of effort (i.e. little if any required recoding)? If so, are there any "gotchas" I should watch out for? Thanks.

  • Dealing w/ Sqlite Join results in a cursor

    - by Bill
    I have a one-many relationship in my local Sqlite db. Pretty basic stuff. When I do my left outer join I get back results that look like this: the resulting cursor has multiple rows that look like this: A1.id | A1.column1 | A1.column2 | B1.a_id_fk | B1.column1 | B1.column2 A1.id | A1.column1 | A1.column2 | B2.a_id_fk | B2.column1 | B2.column2 and so on... Is there a standard practice or method of dealing with results like this ? Clearly there is only A1, but it has many B-n relationships. I am coming close to using multiple queries instead of the "relational db way". Hopefully I am just not aware of the better way to do things. I intend to expose this query via a content provider and I would hate for all of the consumers to have to write the same aggregation logic.

But the webservers at 172.21.37.17 and 172.21.37.24 still didn't respond from the outside world. Although I was able to PPTP VPN in on 321.321.39.10 (interface) which is the outside interface IP address. and it is static mapped to 172.21.37.20. So I'm thinking there must be something wrong with NAT somewhere? no response from 321.321.39.11 to 321.321.39.14.. Could anyone look over the config and please let me know what I've done wrong? Is there something I've missed? well obviously but.. please help! Thank you.

  • JAAS tutorial - how to force application to run with policy

    - by wuntee
    I just went through this tutorial: http://java.sun.com/docs/books/tutorial/security/tour2/index.html And was curios about the basic concept of JAAS... If every applcation needs to be run with the '-Djava.security.manager -Djava.security.policy=...' flags, what is enforcing security? Is it up to the end user to know when any Java application is being run, and modify the executable/script/whatever to include those flags? Or, how does a developer enforce that an application is run with the security manager enabled? The whole concept doesnt seem very functional to me - as it is by default not enabled... Am I missing something?

  • python interactive web data/forms/interface communicating with remote server

    - by decipher
    What's an efficient method (preferably simple as well) for communicating with a remote server and allowing the user to 'interact' with it (IE submit commands, user interface) via the web browser (IE a text box to input commands, and an text area for output, or various command-less abstracted interfaces)? I have the 'standalone' python code finished for communicating and working(terminal/console based right now). My primary concern is with re-factoring the code to suite the web, which involves establishing a connection (python sockets), and maintaining the connection while the user is logged on. some further details: currently using django framework for the basic back end/templates.

Ouch to them…" what is an option strict and explicit anyway? I have googled it up but can't get the idea (because mostly it's Visual Basic, I'm doing PHP)

  • Is it considered bad form to execute a function within a conditional statement?

    - by michael
    Consider a situation in which you need to call successive routines and stop as soon as one returns a value that could be evaluated as positive (true, object, 1, str(1)). It's very tempting to do this: if (fruit = getOrange()) elseif (fruit = getApple()) elseif (fruit = getMango()) else fruit = new Banana(); return fruit; I like it, but this isn't a very recurrent style in what can be considered professional production code. One is likely to rather see more elaborate code like: fruit = getOrange(); if(!fruit){ fruit = getApple(); if(!fruit){ fruit = getMango(); if(!fruit){ fruit = new Banana(); } } } return fruit; According to the dogma on basic structures, is the previous form acceptable? Would you recommend it?

  • How do I combine these similar linq queries into one?

    - by MikeD
    This is probably a basic LINQ question. I have need to select one object and if it is null select another. I'm using linq to objects in the following way, that I know can be done quicker, better, cleaner... public Attrib DetermineAttribution(Data data) { var one = from c in data.actions where c.actionType == Action.ActionTypeOne select new Attrib { id = c.id, name = c.name }; if( one.Count() > 0) return one.First(); var two = from c in data.actions where c.actionType == Action.ActionTypeTwo select new Attrib { id = c.id, name = c.name }; if (two.Count() > 0 ) return two.First(); } The two linq operations differ only on the where clause and I know there is a way to combine them. Any thoughts would be appreciated.

  • C++ input chaining in C#

    - by Monty
    I am trying to learn C# coming from C++. I am writing just some basic console stuff to get a feel for it and was wondering if it is possible to do simple chaining of inputs in C#. For example in C++: cout<<"Enter two numbers: "; cin >> int1 >> int2; You could then just input 3 5 and hit enter and the values will be fine. In C# however I have to split it up(as far as I can tell) like this: Console.Write("Enter the first number: "; int1 = (char)Console.Read(); Console.Writeline(""); Console.Write("Enter the second number: "; int2 = (char)Console.Read(); Maybe I am just missing something.

  • MySQL - Sort on a calculated value based on two dates

    - by Petter Magnusson
    I have the following problem that needs to be solved in a MySQL query: Fields info - textfield date1 - a date field date2 - a date field offset1 - a text field with a number in the first two positions, example "10-High" offset2 - a text field with a number in the first two positions, example "10-High" I need to sort the records by the calculated "sortvalue" based on the current date (today): If today=date2 then sortvalue=offset1*10+offset2*5+1000 else sortvalue=offset1*10+offset2*5 I have quite good understanding of basic SQL with joins etc, but this I am not even sure if its possible...if it helps I could perhaps live with a single formula giving the same sort of effect as the IFs do....ie. before date1 = low value, after date2 = high value...

  • drupal bootstrap script: how to get list of all nodes of type x?

    hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

  • How to add SQL elements to an array in PHP

    - by DanLeaningphp
    So this question is probably pretty basic. I am wanting to create an array from selected elements from a SQL table. I am currently using: $rcount = mysql_num_rows($result); for ($j = 0; $j <= $rcount; $j++) { $row = mysql_fetch_row($result); $patients = array($row[0] => $row[2]); } I would like this to return an array like this: $patients = (bob=>1, sam=>2, john=>3, etc...) Unfortunately, in its current form, this code is either copying nothing to the array or only copying the last element.

  • Using a "vo" for joined data?

    - by keithjgrant
    I'm building a small financial system. Because of double-entry accounting, transactions always come in batches of two or more, so I've got a batch table and a transaction table. (The transaction table has batch_id, account_id, and amount fields, and shared data like date and description are relegated to the batch table). I've been using basic vo-type models for each table so far. Because of this table structure structure, though, transactions will almost always be selected with a join on the batch table. So should I take the selected records and splice them into two separate vo objects, or should I create a "shared" vo that contains both batch and transaction data? There are a few cases in which batch records and/or transaction records. Are there possible pitfalls down the road if I have "overlapping" vo classes?
