  • Why use MySQL over flatfiles?

    - by John
    A friend and I were debating about whether he should use MySQL or a flatfile database for his website's backend. I told him to go with MySQL because it was structured, held records well, and was consistent. He on the other hand said that he would rather go for speed. Reading files is a lot quicker than connecting to MySQL and it made me wonder whether he was right. For example, why not just create a folder for each table, like so: users/ groups/ posts/, within the folders have the files named by ID (1, 2, 3) and then for the data use a format like so: username: John\npassword: e2fc714c4727ee9395f324cd2e7f331f\nemail: [email protected]? In other words, what are the advantages of MySQL over flatfiles?

    - by Refaat
    I'm new at android programming, I'm now trying to make some buttons, I configured these buttons using the following code: The MainActivity class : public class MainActivity extends Activity { /** Called when the activity is first created. */ Button st,nd,center; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); st = (Button)findViewById(R.id.st); st = (Button)findViewById(R.id.center); st = (Button)findViewById(R.id.nd); } } and the XML Layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Hello from animation!!" /> <button android:layout_width="100dp" android:layout_height="50dp" android:text="1st half" android:id="@+id\st" /> // and the other two points defined the same way </LinearLayout> And i got that syntax error: error: Error: No resource type specified (at 'id' with value '@+id\st'). // and the same error with the other two buttons HINT: The R class is imported and accessible from the MainActivity class but it can't read R.id.

  • Parsing secure entries XML file with jquery

    - by user573131
    Apologies if this is elementary. I'm primarily a front end designer/dev. I have webform through a form service called wufoo. Wufoo generates a lovely XML (or json) file that can be grabed and parsed. I'm trying to grab the entries xml feed that is associated with the form and parse it via jquery to show who has entered. Im using the following code (which works with a local xml file). http://bostonwebsitemakeover.com/2/test <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"></script> <script> $(document).ready(function () { $.ajax({ type: "GET", url: "people.xml", dataType: "xml", success: xmlParser }); }); function xmlParser(xml) { $('#load').fadeOut(); $(xml).find("Entry").each(function () { $(".main").append('<div class="entry">' + $(this).find("Field1").text() + ' ' + $(this).find("Field2").text() + ' http://twitter.com/' + $(this).find("Field17").text() + '</div>'); $(".entry").fadeIn(1000); }); } </script> My XML file contains the following: <?xml version="1.0"?> <Entries> <Entry> <EntryId>1</EntryId> <Field1>Meaghan</Field1> <Field2>Severson</Field2> <Field17/> </Entry> <Entry> <EntryId>2</EntryId> <Field1>Michael</Field1> <Field2>Flint</Field2> <Field17>michaelflint</Field17> </Entry> <Entry> <EntryId>3</EntryId> <Field1>Niki</Field1> <Field2>Brown</Field2> <Field17>nikibrown</Field17> </Entry> <Entry> <EntryId>4</EntryId> <Field1>Niki</Field1> <Field2>Brown</Field2> <Field17>nikibrown</Field17> </Entry> </Entries> I'm wondering how I would do this with the xml file hosted on the wufoo (which is https) So I guess Im asking how do I authenticate the feed via jquery? Or do i need to do this via json? Could someone explain how?

  • open,edit and save xml file with schema using php

    - by Neat
    Hy... I'm new in XML Schema, XSL,... (I have basic understanding) On web page: http://w3schools.com/xsl/xsl_editxml.asp is shown example for open,edit,save xml file, but with asp. Do anyone know how can i open/edit and save xml file using php for next example: <?xml version="1.0" encoding="ISO-8859-1"?> <tools> <tool id="1"> <field id="prodName"> <value>HAMMER HG2606</value> </field> <field id="prodNo"> <value>32456240</value> </field> <field id="price"> <value>$30.00</value> </field> </tool> <tool id="2"> <field id="prodName"> <value>Audi</value> </field> <field id="prodNo"> <value>88885</value> </field> <field id="price"> <value>$26.00</value> </field> </tool> </tools> and do i need <tool id="2"> or just <tool> is enough. Thanks very much on replay, and i don't need another xsl like shown on w3s, just fine is refresh submitted php file after submit (will do something with ajax after). I saw replay from Mr. Writman on questions/377632/add-update-and-edit-an-xml-file-with-php but that is for now 2 complex for me...:) is there any simpler answer (solution). Thanks in advance!!!

  • JUnit: checking if a void method gets called

    - by nkr1pt
    I have a very simple filewatcher class which checks every 2 seconds if a file has changed and if so, the onChange method (void) is called. Is there an easy way to check ik the onChange method is getting called in a unit test? code: public class PropertyFileWatcher extends TimerTask { private long timeStamp; private File file; public PropertyFileWatcher(File file) { this.file = file; this.timeStamp = file.lastModified(); } public final void run() { long timeStamp = file.lastModified(); if (this.timeStamp != timeStamp) { this.timeStamp = timeStamp; onChange(file); } } protected void onChange(File file) { System.out.println("Property file has changed"); } } @Test public void testPropertyFileWatcher() throws Exception { File file = new File("testfile"); file.createNewFile(); PropertyFileWatcher propertyFileWatcher = new PropertyFileWatcher(file); Timer timer = new Timer(); timer.schedule(propertyFileWatcher, 2000); FileWriter fw = new FileWriter(file); fw.write("blah"); fw.close(); Thread.sleep(8000); // check if propertyFileWatcher.onChange was called file.delete(); }

  • Compiling SWC file from FDT

    - by WillDonohoe
    Hi guys, I've made a library which I'd like to compile to an SWC file, I've tried to do this in FDT by choosing FDT AS3 Library as Run settings, but all I end up with is a 0kb .swc file. Does anybody know what I'm doing wrong? I can't find much when I google it either, if anybody has a quick walkthrough on how to do it saved in your bookmarks or something, that would be great! Many thanks, Will

  • Distributing a bundle of files across an extranet

    - by John Zwinck
    I want to be able to distribute bundles of files, about 500 MB per bundle, to all machines on a corporate "extranet" (which is basically a few LANs connected using various private mechanisms, including leased lines and VPN). The total number of hosts is roughly 100, and the goal is to get a copy of the bundle from one host onto all the other hosts reliably, quickly, and efficiently. One important issue is that some hosts are grouped together on single fast LANs in which case the network I/O should be done once from one group to the next and then within each group between all the peers. This is as opposed to a strict central server system where multiple hosts might each fetch the same bundle over a slow link, rather than once via the slow link and then between each other quickly. A new bundle will be produced every few days, and occasionally old bundles will be deleted (but that problem can be solved separately). The machines in question happen to run recent Linuxes, but bonus points will go to solutions which are at least somewhat cross-platform (in which case the bundle might differ per platform but maybe the same mechanism can be used). That's pretty much it. I'm not opposed to writing some code to handle this, but it would be preferable if it were one of bash, Python, Ruby, Lua, C, or C++.

  • WebBrowser control not navigating to links to "file://" protocol URIs

    - by Nick Butler
    I am setting the DocumentText property to an HTML string that contains links like: <a href="file:///D:/dir/file.html">NewPage</a> The links are shown properly in the WebBrowser, but nothing happens when I click them. The Navigating, Navigated and DocumentComplete events do not fire - nothing seems to happen at all. AllowNavigation is true and other links using HTTP are working. Any ideas please? Nick

  • Access: strange results with queries against MDB file

    - by Craig Johnston
    I am running the following SQL against an MDB file, a copy of which is located here: http://hotfile.com/dl/40641614/2353dfc/test.mdb.html (perfectly clean file, no macros or viruses) SELECT datediff("d", MAX(invoice.date), Now) As Date_Diff , MAX(invoice.date) AS max_invoice_date , customer.number AS customer_number FROM invoice INNER JOIN customer ON invoice.customer_number = customer.number GROUP BY customer.number If the the following was added: HAVING datediff("d", MAX(invoice.date), Now) > 365 would this simply exclude rows with Date_Diff <= 365? What should be the effect of the HAVING clause here?
