  • Removing trailing newline character from fgets() input

    - by sfactor
    i am trying to get some data from the user and send it to another function in gcc. the code is something like this. printf("Enter your Name: "); if(!(fgets(Name, sizeof Name, stdin) != NULL)) { fprintf(stderr, "Error reading Name.\n"); exit(1); } However, i find that it has an \n character in the end. so if i enter John it ends up sending John\n. so how do i remove that \n and send a proper string.

  • Update database settings in properties file in Spring

    - by mvg
    Hi all, I am trying to create a Database Manager page which shows the database details on page load and updates the database settings when the user press submit I followed this tutorial and set the database settings in properties file. I managed to update the database settings in properties file programmatically. When I retrieved the database settings using the following code DriverManagerDataSource databaseSource = (DriverManagerDataSource)context.getBean("dataSource"); databaseSource.getUsername(); I managed to get the old value and unable to get the new value This is the mapping in applicationContext.xml file <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location"> <value>classpath:/bundle/database.properties</value> </property> </bean> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> I checked the properties file and found it to be updated with the latest input. What am I missing? Thanks in advance P.S I am using JSF1.2 with Spring 3 Update Just making my requirement simple. I am creating a setparate dbsettings page, so that when user wishes to connect to different database he/she can just enter the details in dbsettings page and connect

  • How Do I Prevent Rails From Treating Edit Fields_For Differently From New Fields_For

    - by James
    I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

  • How to convert row data into columns in SQL

    - by iHeartDucks
    Hi, I have looked into pivot but I think it requires an aggregate function which I do not need (I think). The result of my query is this Name Property Name PropertyValue ---------- ---------- ---------- lorem Work Phone 000.111.2020 ipsum Email [email protected] To Name Work Phone Email ---------- ---------- ---------- lorem 000.111.2020 [email protected] ipsum 001.101.2010 [email protected] I don't think I should use pivot here because I don't need to aggregate anything, I just want the row data to become a column.

  • Specify ApplicationName when using ASP.NET Web Site Administration Tool

    - by ProfK
    This tool is supposed to configure users and roles etc., but when I use it on a new web site, with a new aspnetdb database, it adds a record to the aspnet_Applications table with the ApplicationName and the LoweredApplicationName fields set to /. I think it would make more sense if it actually used the application name, i.e. the web site name. Can I safely just change the application name? Is there a better way of configuring these things?

Here is the element that I'm working with: <textBox id="Airfare" value="" label="text 1"/> Here is the XSLT template I'm using: <xsl:template match="textBox"> <div> <xsl:choose> <xsl:when test="@label"> <xsl:value-of select="@label"/> </xsl:when> <xsl:otherwise> <xsl:text>No Label Defined</xsl:text> </xsl:otherwise> </xsl:choose> <xsl:element name="input"> <xsl:attribute name="type">text</xsl:attribute> <xsl:for-each select="@*"> <xsl:choose> <xsl:when test="@id"> <xsl:attribute name="name">form_<xsl:value-of select="@id"/></xsl:attribute> <xsl:attribute name="id">form_<xsl:value-of select="@id"/></xsl:attribute> </xsl:when> <xsl:when test="@label"> </xsl:when> <xsl:otherwise> <xsl:copy-of select="current()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each> </xsl:element> </div> And when I generate the HTML using PHP I get this: <div>text 1<input type="text" id="Airfare" value="" label="text 1"></div> As you can see it didn't add form_ to the id attribute it didn't generate a name attribute and it didn't skip over the label attribute.

  • Having issues with initializing character array

    - by quandrum
    Ok, this is for homework about hashtables, but this is the simple stuff I thought I was able to do from earlier classes, and I'm tearing my hair out. The professor is not being responsive enough, so I thought I'd try here. We have a hashtable of stock objects.The stock objects are created like so: stock("IBM", "International Business Machines", 2573, date(date::MAY, 23, 1967)) my constructor looks like: stock::stock(char const * const symbol, char const * const name, int sharePrice, date priceDate): symbol(NULL), name(NULL), sharePrice(sharePrice), dateOfPrice(priceDate) { setSymbol(symbol); setName(name); } and setSymbol looks like this: (setName is indentical): void stock::setSymbol(const char* symbol) { if (this->symbol) delete [] this->symbol; this->symbol = new char[strlen(symbol)+1]; strcpy(this->symbol,symbol); } and it refuses to allocate on the line this->symbol = new char[strlen(symbol)+1]; with a std::bad_alloc. name and symbol are declared char * name; char * symbol; I feel like this is exactly how I've done it in previous code.I'm sure it's something silly with pointers. Can anyone help?

  • Scaling larger Image problem.

    - by krishna
    Hi, I m developing flex application, in which I want to Draw Image from User local hard-drive to the canvas of size 640x360. User can choose Image of bigger resolution & is scaled to Canvas size. But if user selected images of larger resolution like 3000x2000, the scaling take lot time & freezes the application until scale done. Is there any method to scale image faster or kind of threading can be done? I am using matrix to scale Image as below: var mat:Matrix = new Matrix(); var scalex:Number = canvasScreen.width/content.width; var scaley:Number = canvasScreen.height/content.height; mat.scale(scalex,scaley); canvasScreen.graphics.clear(); canvasScreen.graphics.beginBitmapFill(content.bitmapData,mat);

  • Jboss logging issue - pl check this

    - by balaji
    I’m Working as deployer and server administrator. We use Jboss 4.0x AS to deploy our applications. The issue I'm facing is, Whenever we redeploy/restart the server, server.log is getting created but after sometime the logging goes off. Yes it is not at all updating the server.log file. Due to this, we could not trace the other critical issues we have. Actually we have two separate nodes and we do deploy/restarting the server separately on two nodes. We are facing the issue in both of our test and production environment. I could not trace out where exactly the issue is. Could you please help me in resolving the issue? If we have any other issues, we can check the log files. If log itself is not getting updated/logged, how can we move further in analyzing the issues without the recent/updated logs? Below are the logs found in the stdout.log: 18:55:50,303 INFO [Server] Core system initialized 18:55:52,296 INFO [WebService] Using RMI server codebase: http://kl121tez.is.klmcorp.net:8083/ 18:55:52,313 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:log4j.xml 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFTraceLogger without a class name. 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFMessageLogger without a class name. 18:55:54,273 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheTraceLogger without a class name. 18:55:54,274 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheMessageLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCTraceLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCMessageLogger without a class name. 18:55:56,059 INFO [ServiceEndpointManager] WebServices: jbossws-1.0.3.SP1 (date=200609291417) 18:55:56,635 INFO [Embedded] Catalina naming disabled 18:55:56,671 INFO [ClusterRuleSetFactory] Unable to find a cluster rule set in the classpath.

  • Help with PHP simplehtmldom - Modifiying a form.

    - by onemyndseye
    Ive gotten some great help here and I am so close to solving my problem that I can taste it. But I seem to be stuck. I need to scrape a simple form from a local webserver and only return the lines that match a users local email (i.e. onemyndseye@localhost). simplehtmldom makes easy work of extracting the correct form element: foreach($html->find('form[action*="delete"]') as $form) echo $form; Returns: <form action="/delete" method="post"> <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php"> http://www.linux.com/rss/feeds.php </a> [email: onemyndseye@localhost (Default) ]<br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml"> http://www.ubuntu.com/rss.xml </a> [email: onemyndseye@localhost (Default) ]<br /> However I am having trouble making the next step. Which is returning lines that contain 'onemyndseye@localhost' and removing it so that only the following is returned: <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php">http://www.linux.com/rss/feeds.php</a> <br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml">http://www.ubuntu.com/rss.xml</a> <br /> Thanks to the wonderful users of this site Ive gotten this far and can even return just the links but I am having trouble getting the rest... Its important that the complete <input> tags are returned EXACTLY as shown above as the id and name values will need to be passed back to the original form in post data later on. Thanks in advance!

    Hi, I'm trying to solve the problem: when a user is being logged into a WebSite (via user control .ascx stored on the Master Page), it's name is being stored in a Page.User.Identity.Name property. OK, but how to retrieve that user name in the controller ? Is it possible without registering System.Security.Principal namespace in the controller ? In the other words - the controller must know whose user wants to do some action (e.g. change account data). I could store it's name in the Html.Hidden control on each View but I don't want to have a mess in my Views

I am using <?php echo form_open('home'); ?> and <?php echo form_close(); ?> The form fields within the form, which I'm generating as follows are being rendered fine, but there is simply no form around them?! <?php $data = array( 'name'=> 'name', 'id'=> 'name', 'class'=>'textfield', 'value' => set_value('name') ); echo form_input($data); ?> Any ideas - I've used CI on a few apps, and this is the first time I've come across this issue. I've got all the helpers etc called correctly, as this is working perfectly in the development environment.

  • Get the property, as a string, from an Expression<Func<TModel,TProperty>>

    - by Jaxidian
    I use some strongly-typed expressions that get serialized to allow my UI code to have strongly-typed sorting and searching expressions. These are of type Expression<Func<TModel,TProperty>> and are used as such: SortOption.Field = (p => p.FirstName);. I've gotten this working perfectly for this simple case. The code that I'm using for parsing the "FirstName" property out of there is actually reusing some existing functionality in a third-party product that we use and it works great, until we start working with deeply-nested properties(SortOption.Field = (p => p.Address.State.Abbreviation);). This code has some very different assumptions in the need to support deeply-nested properties. As for what this code does, I don't really understand it and rather than changing that code, I figured I should just write from scratch this functionality. However, I don't know of a good way to do this. I suspect we can do something better than doing a ToString() and performing string parsing. So what's a good way to do this to handle the trivial and deeply-nested cases? Requirements: Given the expression p => p.FirstName I need a string of "FirstName". Given the expression p => p.Address.State.Abbreviation I need a string of "Address.State.Abbreviation" While it's not important for an answer to my question, I suspect my serialization/deserialization code could be useful to somebody else who finds this question in the future, so it is below. Again, this code is not important to the question - I just thought it might help somebody.
