  • Configuring Cruise Control Net with sourcesafe - Unable to load array item 'executable'

    - by albert
    Hi all, I'm trying to create a continuous integration environment. To do so, I've used a guide that can be found at http://www.15seconds.com/issue/040621.htm. In this step by step, the goal is to create a CI with CCNet, NAnt, NUni, NDoc, FxCop and source safe. I've been able to create my build by using the command prompt (despite the the different versions issues). The problem has come with the configuration of ccnet.config I've made some changes because of the new versions, but I'm still getting errors when starting the CCNet server. Can anyone help me to fix this issue or point where to find a guide with this scenario? The error that I'm getting: Unable to instantiate CruiseControl projects from configuration document. Configuration document is likely missing Xml nodes required for properly populating CruiseControl configuration. Unable to load array item 'executable' - Cannot convert from type System.String to ThoughtWorks.CruiseControl.Core.ITask for object with value: "\DevTools\nant\bin\NAnt.exe" Xml: E:\DevTools\nant\bin\NAnt.exe My CCNet config file below: <cruisecontrol> <project name="BuildingSolution"> <webURL>http://localhost/ccnet</webURL> <modificationDelaySeconds>10</modificationDelaySeconds> <triggers> <intervaltrigger name="continuous" seconds="60" /> </triggers> <sourcecontrol type="vss" autoGetSource="true"> <ssdir>E:\VSS\</ssdir> <executable>C:\Program Files\Microsoft Visual SourceSafe\SS.EXE</executable> <project>$/CCNet/slnCCNet.root/slnCCNet</project> <username>Albert</username> <password></password> </sourcecontrol> <prebuild type="nant"> <executable>E:\DevTools\nant\bin\NAnt.exe</executable> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <buildTimeoutSeconds>300</buildTimeoutSeconds> </prebuild> <tasks> <nant> <executable>E:\DevTools\nant\bin\nant.exe</executable> <nologo>true</nologo> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <targetList> <target>build</target> </targetList> <buildTimeoutSeconds>6000</buildTimeoutSeconds> </nant> </tasks> <publishers> <merge> <files> <file>E:\Builds\buildingsolution\latest\*-results.xml</file> </files> </merge> <xmllogger /> </publishers> </project> </cruisecontrol> enter code here

  • How do I use connect to DB2 with DBI and mod_perl?

    - by Matthew
    I'm having issues with getting DBI's IBM DB2 driver to work with mod_perl. My test script is: #!/usr/bin/perl use strict; use CGI; use Data::Dumper; use DBI; { my $q; my $dsn; my $username; my $password; my $sth; my $dbc; my $row; $q = CGI->new; print $q->header; print $q->start_html(); $dsn = "DBI:DB2:SAMPLE"; $username = "username"; $password = "password"; print "<pre>".$q->escapeHTML(Dumper(\%ENV))."</pre>"; $dbc = DBI->connect($dsn, $username, $password); $sth = $dbc->prepare("SELECT * FROM SOME_TABLE WHERE FIELD='SOMETHING'"); $sth->execute(); $row = $sth->fetchrow_hashref(); print "<pre>".$q->escapeHTML(Dumper($row))."</pre>"; print $q->end_html; } This script works as CGI but not under mod_perl. I get this error in apache's error log: DBD::DB2::dr connect warning: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /usr/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 190. DBI connect('SAMPLE','username',...) failed: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /data/www/perl/test.pl line 15 First of all, why is it using ODBC? The native DB2 driver is installed (hence it works as CGI). Running Apache 2.2.3, mod_perl 2.0.4 under RHEL5. This guy had the same problem as me: http://www.mail-archive.com/[email protected]/msg22909.html But I have no idea how he fixed it. What does mod_php4 have to do with mod_perl? Any help would be greatly appreciated, I'm having no luck with google. Update: As james2vegas pointed out, the problem has something to do with PHP: I disable PHP all together I get the a different error: Total Environment allocation failure! Did you set up your DB2 client environment? I believe this error is to do with environment variables not being set up correctly, namely DB2INSTANCE. However, I'm not able to turn off PHP to resolve this problem (I need it for some legacy applications). So I now have 2 questions: How can I fix the original issue without disabling PHP all together? How can I fix the environment issue? I've set DB2INSTANCE, DB2_PATH and SQLLIB variables correctly using SetEnv and PerlSetEnv in httpd.conf, but with no luck. Note: I've edited the code to determine if the problem was to do with Global Variable Persistence.

  • Process spawned by exec-maven-plugin blocks the maven process

    - by Arnab Biswas
    I am trying to execute the following scenario using maven : pre-integration-phase : Start a java based application using a main class (using exec-maven-plugin) integration-phase : Run the integration test cases (using maven-failsafe-plugin) post-integration-phase: Stop the application gracefully (using exec-maven-plugin) Here is pom.xml snip: <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.2.1</version> <executions> <execution> <id>launch-myApp</id> <phase>pre-integration-test</phase> <goals> <goal>exec</goal> </goals> </execution> </executions> <configuration> <executable>java</executable> <arguments> <argument>-DMY_APP_HOME=/usr/home/target/local</argument> <argument>-Djava.library.path=/usr/home/other/lib</argument> <argument>-classpath</argument> <classpath/> <argument>com.foo.MyApp</argument> </arguments> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-failsafe-plugin</artifactId> <version>2.12</version> <executions> <execution> <goals> <goal>integration-test</goal> <goal>verify</goal> </goals> </execution> </executions> <configuration> <forkMode>always</forkMode> </configuration> </plugin> </plugins> If I execute mvn post-integration-test, my application is getting started as a child process of the maven process, but the application process is blocking the maven process from executing the integration tests which comes in the next phase. Later I found that there is a bug (or missing functionality?) in maven exec plugin, because of which the application process blocks the maven process. To address this issue, I have encapsulated the invocation of MyApp.java in a shell script and then appended “/dev/null 2&1 &” to spawn a separate background process. Here is the snip (this is just a snip and not the actual one) from runTest.sh: java - DMY_APP_HOME =$2 com.foo.MyApp > /dev/null 2>&1 & Although this solves my issue, is there any other way to do it? Am I missing any argument for exec-maven-plugin?

  • eXML-PARSER output contains unwanted hash references

    - by seaworthy
    So I wrote a parser routine to take one xml file and reparse into another one. This code I later modified to split a large xml file into many small xml files. I am having a problem with an output. Parsing works fine the only thing output also includes unwanted strings like HASH(0x19f9b58), I am not sure why and need set of friendly eyes. use Encode; use XML::Parser; my $parser = XML::Parser->new( Handlers => {Start => \&handle_elem_start, End => \&handle_elem_end,Char => \&handle_char_data,}); my $record; my $file = shift @ARGV; if( $file ) {$parser->parsefile( $file );} exit; sub handle_elem_start { my( $expat, $name, %atts ) = @_; if ($name eq 'articles'){$file="_data.xml";unlink($file);} $record .= "<"; $record .= "$name"; foreach my $key (keys %atts){$record .= " $key=\"$atts{$key}\"";} $record .= ">"; } sub handle_char_data { my( $expat, $text ) = @_; $text = decode_utf8( $text ); $record .= "$text"; } sub handle_elem_end { my( $expat, $name ) = @_; $record .= "</$name>"; if( $name eq 'article' ) { open (MYFILE, '>>'.$file); print MYFILE $record; close (MYFILE); print $record; $record = {}; } return unless( $name eq 'article' ); } Sample output: ... </article>HASH(0x19f9b40) <article doi="10.1103/PhysRevSeriesI.9.304"> <journal short="Phys.

  • Firefox not running jQuery for XHTML output

    - by ScottSEA
    Okay, I did a crappy job of describing the issue in my previous post. I think the discussion got sidetracked from the core issue - so I'm going to try again. Mea Culpa to Elzo Valugi about the aforementioned thread. I have an XML file: <?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type="text/xsl" href="wtf.xsl"?> <Paragraphs> <Paragraph>Hi</Paragraph> </Paragraphs> Simple enough. I also have a stylesheet to create XHTML output: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns="http://www.w3.org/1999/xhtml" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" omit-xml-declaration="yes"/> <xsl:template match="/*"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>FF-JS-XHTML WTF</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="wtf.js"></script> </head> <body> <xsl:apply-templates /> </body> </html> </xsl:template> <xsl:template match="Paragraph"> <p> <xsl:apply-templates /> </p> </xsl:template> </xsl:stylesheet> Last but not least, I have the following jQuery in toto (wtf.js, from the script tag in the stylesheet): $(function() { alert('Hiya!'); $('<p>Hello</p>').appendTo('body'); }); Extremely simple, but sufficient for the demonstration. When I run this in Internet Explorer, I get the alert 'Hiya!' as well as the expected: Hi Hello but when I run it in Firefox (3.0.1), I still get the alert, but the jQuery does not insert the paragraph into the DOM, and I just get this: Hi If I change the stylesheet to method="html" it works fine, and I get (along with the alert): Hi Hello Why doesn't Firefox run the jQuery with an XHTML document? Has anyone any experience with this problem? EDIT: ADDITIONAL INFO I can successfully insert elements into the documents this way in Firefox (method="xml"): var frag = document.createDocumentFragment(); var p = document.createElement('p'); p.appendChild(document.createTextNode('Ipsum Lorem')); frag.appendChild(p); $('body').append(frag); but I'm running into a similar problem with the .remove() method. It is looking more and more that Firefox doesn't construct a DOM from XML that jQuery can relate to, or somesuch.

  • Sending emails in web applications

    - by Denise
    Hi everyone, I'm looking for some opinions here, I'm building a web application which has the fairly standard functionality of: Register for an account by filling out a form and submitting it. Receive an email with a confirmation code link Click the link to confirm the new account and log in When you send emails from your web application, it's often (usually) the case that there will be some change to the persistence layer. For example: A new user registers for an account on your site - the new user is created in the database and an email is sent to them with a confirmation link A user assigns a bug or issue to someone else - the issue is updated and email notifications are sent. How you send these emails can be critical to the success of your application. How you send them depends on how important it is that the intended recipient receives the email. We'll look at the following four strategies in relation to the case where the mail server is down, using example 1. TRANSACTIONAL & SYNCHRONOUS The sending of the email fails and the user is shown an error message saying that their account could not be created. The application will appear to be slow and unresponsive as the application waits for the connection timeout. The account is not created in the database because the transaction is rolled back. TRANSACTIONAL & ASYNCHRONOUS The transactional definition here refers to sending the email to a JMS queue or saving it in a database table for another background process to pick up and send. The user account is created in the database, the email is sent to a JMS queue for processing later. The transaction is successful and committed. The user is shown a message saying that their account was created and to check their email for a confirmation link. It's possible in this case that the email is never sent due to some other error, however the user is told that the email has been sent to them. There may be some delay in getting the email sent to the user if application support has to be called in to diagnose the email problem. NON-TRANSACTIONAL & SYNCHRONOUS The user is created in the database, but the application gets a timeout error when it tries to send the email with the confirmation link. The user is shown an error message saying that there was an error. The application is slow and unresponsive as it waits for the connection timeout When the mail server comes back to life and the user tries to register again, they are told their account already exists but has not been confirmed and are given the option of having the email re-sent to them. NON-TRANSACTIONAL & ASYNCHRONOUS The only difference between this and transactional & asynchronous is that if there is an error sending the email to the JMS queue or saving it in the database, the user account is still created but the email is never sent until the user attempts to register again. What I'd like to know is what have other people done here? Can you recommend any other solutions other than the 4 I've mentioned above? What's a reasonable way of approaching this problem? I don't want to over-engineer a system that's dealing with the (hopefully) rare situation where my mail server goes down! The simplest thing to do is to code it synchronously, but are there any other pitfalls to this approach? I guess I'm wondering if there's a best practice, I couldn't find much out there by googling.

  • Why doesn't my implementation of ElGamal work for long text strings?

    - by angstrom91
    I'm playing with the El Gamal cryptosystem, and my goal is to be able to encipher and decipher long sequences of text. I have come up with a method that works for short sequences, but does not work for long sequences, and I cannot figure out why. El Gamal requires the plaintext to be an integer. I have turned my string into a byte[] using the .getBytes() method for Strings, and then created a BigInteger out of the byte[]. After encryption/decryption, I turn the BigInteger into a byte[] using the .toByteArray() method for BigIntegers, and then create a new String object from the byte[]. This works perfectly when i call ElGamalEncipher with strings up to 129 characters. With 130 or more characters, the output produced from ElGamalDecipher is garbled. Can someone suggest how to solve this issue? Is this an issue with my method of turning the string into a BigInteger? If so, is there a better way to turn my string of text into a BigInteger and back? Below is my encipher/decipher code with a program to demonstrate the problem. import java.math.BigInteger; public class Main { static BigInteger P = new BigInteger("15893293927989454301918026303382412" + "2586402937727056707057089173871237566896685250125642378268385842" + "6917261652781627945428519810052550093673226849059197769795219973" + "9423619267147615314847625134014485225178547696778149706043781174" + "2873134844164791938367765407368476144402513720666965545242487520" + "288928241768306844169"); static BigInteger G = new BigInteger("33234037774370419907086775226926852" + "1714093595439329931523707339920987838600777935381196897157489391" + "8360683761941170467795379762509619438720072694104701372808513985" + "2267495266642743136795903226571831274837537691982486936010899433" + "1742996138863988537349011363534657200181054004755211807985189183" + "22832092343085067869"); static BigInteger R = new BigInteger("72294619754760174015019300613282868" + "7219874058383991405961870844510501809885568825032608592198728334" + "7842806755320938980653857292210955880919036195738252708294945320" + "3969657021169134916999794791553544054426668823852291733234236693" + "4178738081619274342922698767296233937873073756955509269717272907" + "8566607940937442517"); static BigInteger A = new BigInteger("32189274574111378750865973746687106" + "3695160924347574569923113893643975328118502246784387874381928804" + "6865920942258286938666201264395694101012858796521485171319748255" + "4630425677084511454641229993833255506759834486100188932905136959" + "7287419551379203001848457730376230681693887924162381650252270090" + "28296990388507680954"); public static void main(String[] args) { FewChars(); System.out.println(); ManyChars(); } public static void FewChars() { //ElGamalEncipher(String plaintext, BigInteger p, BigInteger g, BigInteger r) BigInteger[] cipherText = ElGamal.ElGamalEncipher("This is a string " + "of 129 characters which works just fine .

When I open a pop-up using the 'createPopUp' method, I've got this index out of bounds error message : RangeError: The supplied index is out of bounds. at mx.core::FTETextField/getLineMetrics()[E:\dev\4.y\frameworks\projects\spark\src\mx\core\FTETextField.as:2169] at mx.core::UIFTETextField/get baselinePosition()[E:\dev\4.y\frameworks\projects\spark\src\mx\core\UIFTETextField.as:784] at mx.controls::DateChooser/get baselinePosition()[E:\dev\4.y\frameworks\projects\mx\src\mx\controls\DateChooser.as:994] at spark.components::Group/get baselinePosition()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\Group.as:282] at spark.layouts::ConstraintLayout/parseElementConstraints()[E:\dev\4.y\frameworks\projects\spark\src\spark\layouts\ConstraintLayout.as:1818] at spark.layouts::ConstraintLayout/parseConstraints()[E:\dev\4.y\frameworks\projects\spark\src\spark\layouts\ConstraintLayout.as:1632] at spark.layouts::ConstraintLayout/measure()[E:\dev\4.y\frameworks\projects\spark\src\spark\layouts\ConstraintLayout.as:414] at spark.components.supportClasses::GroupBase/measure()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\supportClasses\GroupBase.as:1148] at mx.core::UIComponent/http://www.adobe.com/2006/flex/mx/internal::measureSizes()[E:\dev\4.y\frameworks\projects\framework\src\mx\core\UIComponent.as:8506] at mx.core::UIComponent/validateSize()[E:\dev\4.y\frameworks\projects\framework\src\mx\core\UIComponent.as:8430] at spark.components::Group/validateSize()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\Group.as:1012] at mx.managers::LayoutManager/validateClient()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\LayoutManager.as:987] at mx.managers::PopUpManagerImpl/addPopUp()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\PopUpManagerImpl.as:382] at mx.managers::PopUpManagerImpl/createPopUp()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\PopUpManagerImpl.as:232] at mx.managers::PopUpManager$/createPopUp()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\PopUpManager.as:139] at views::AddProjects/loadAddProjectPopUp()[C:\Users\Laura\Web\spidermak\spidermak\src\views\AddProjects.mxml:184] at views::AddProjects/___AddProjects_Button1_click()[C:\Users\Laura\Web\spidermak\spidermak\src\views\AddProjects.mxml:838] It seems that this error is caused by a "dateChooser" component in my popup : <mx:DateChooser id="endDate"/> When I comment this line, the error is no longer thrown and the popup loads correctly. It's really weird because I didn't have this issue until this morning. All I did in the meantime was changing some layout-related stuff, but I don't see what is would have to do with this problem. I don't get it... Does anyone have a clue about how to fix this ? I need my DateChooser ! Thanks ! Laura EDIT - It seems that the problem is not caused by the DateChooser itself, but by the FormItem around it. Here's what my code looks like : <Form width="100%"> [...] <s:HGroup width="100%"> <s:FormItem label="Date de début"> <mx:DateChooser id="startDate" firstDayOfWeek="1"/> </s:FormItem> <s:FormItem label="Date de fin"> <mx:DateChooser id="endDate" firstDayOfWeek="1"/> </s:FormItem> </s:HGroup> </Form> If I remove the two FormItems, it works. Could anyone explain me why? Thanks !

  • Why is my code returning a Null Object Refrence error when using WatIn?

    - by Fuzz Evans
    I keep getting a Null Object Refrence Error, but can't tell why. I have a CSV file that contains 100 urls. The file is read into an array called "lines". public partial class Form1 : System.Windows.Forms.Form { string[] lines; public Form1() ... private void ReadLinksIntoMemory() { //this reads the chosen csv file into our "lines" array //and splits on comma's and new lines to create new objects within the array using (StreamReader sr = new StreamReader(@"C:\temp.csv")) { //reads everything in our csv into 1 long line string fileContents = sr.ReadToEnd(); //splits the 1 long line read in into multiple objects of the lines array lines = fileContents.Split(new string[] { ",", Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); sr.Dispose(); } } The next part is where I get the null object error. When I try to use WatIn to go to the first item in the lines array it says I'm referencing a null object. private void GoToEditLinks() { for (int i = 0; i < lines.Length; i++) { //go to each link sequentially myIE.GoTo(lines[i].ToString()); //sleep so we can make sure the page loads System.Threading.Thread.Sleep(5000); } } When I debug the code it says that the GoTo request calls lines which is null. It seems like I need to declare the array, but don't I need to tell it an exact size to do that? Example: lines = new string[10] I thought I could use the lines.Length to tell it how big to make the array but that didn't work. What is weird to me is I can use the following code without problem: //returns the accurate number of urls that were in the CSV we read in earlier txtbx1.text = lines.Length; //or //this returns the last entry in the csv, as well as the last entry in the array TextBox2.Text = lines[lines.Length - 1]; I am confused why the array clearly has items in it, they can be called to fill a text box, but when I try to call them in my for loop it says its a null reference? UPDATE: By placing my cursor on both calls to lines and pressing f12 I find they both go to the same instance. The thought next is that I am not calling ReadLinksIntoMemory in time, below is my code: private void button1_Click(object sender, EventArgs e) { button1.Enabled = false; ReadLinksIntoMemory(); GoToEditLinks(); button1.Enabled = true; } Unless I'm mistaken the code says that the ReadLinksIntoMemory method must complete before GoToEditLinks can be called? If ReadLinksIntoMemory didn't finish in time I shouldn't be able to fill my text boxes with the lines array length and/or last entry. UPDATE: Stepping into the method GoToEditLinks() I see that lines is null before it calls: myIE.GoTo(lines[i]); but when it hits the goto command the value changes from null to the url it is suppose to go to, but at that same time it gives me the null object error? UPDATE: I added a IsNullOrEmpty check method and lines array passes it without any issue. I'm beginning to think it is an issue with WatIn and the myIE.GoTo command. I think this is the stack trace/call stack? Program.exe!Program.Form1.GoToEditLinks() Line 284 C# Program.exe!Program.Form1.button1_Click(object sender, System.EventArgs e) Line 191 + 0x8 bytes C# [External Code] Program.exe!Program.Program.Main() Line 18 + 0x1d bytes C# [External Code]

  • Perl IO modules possibly causing issues in Net::DNS module

    - by Rich
    Hi! I’m porting some software that I wrote for a White Russian OpenWRT system to a new Kamikaze 8.09.1 OpenWRT system but I am having some serious issues that I’m hoping you can help me with. Old system Linux kernel 2.4.34 MIPSEL arch Perl 5.8.7 Net::DNS 0.48 IO 1.21 IO::Socket 1.28 IO::Socket::INET 1.28 New system Linux kernel 2.6.26.8 MIPS arch Perl 5.10.0 Net::DNS 0.66 IO 1.23_01 IO::Socket 1.30_01 IO::Socket::INET 1.31 First, let me provide some background information… I am trying to resolve my server (clearprobe.winbeam.com) from within my Perl program and see the following if I enable debugging in Net::DNS: resolve: Server 'clearprobe-ddns.winbeam.com' ;; query(clearprobe-ddns.winbeam.com) ;; setting up an AF_INET() family type UDP socket ;; send_udp(192.168.88.1:53) ;; send_udp(4.2.2.2:53) ;; send_udp(192.168.88.1:53) ;; send_udp(4.2.2.2:53) resolve: res->errorstring: query timed out Both of these servers resolve clearprobe.winbeam.com fine from the command line: root@cwb-2-11:~# echo “nameserver 192.168.88.1” > /etc/resolv.conf root@cwb-2-11:~# nslookup clearprobe-ddns.winbeam.com Server: 192.168.88.1 Address 1: 192.168.88.1 router Name: clearprobe-ddns.winbeam.com Address 1: 64.13.48.40 64-13-48-40.war.clearwire-dns.net root@cwb-2-11:~# echo “nameserver 4.2.2.2” > /etc/resolv.conf root@cwb-2-11:~# nslookup clearprobe-ddns.winbeam.com Server: 4.2.2.2 Address 1: 4.2.2.2 vnsc-bak.sys.gtei.net Name: clearprobe-ddns.winbeam.com Address 1: 64.13.48.40 64-13-48-40.war.clearwire-dns.net Using Perl’s call to the C gethostbyaddr() function works fine, but I need to do another lookup later in the software which requires that I specify the nameserver (clearprobe-ddns.winbeam.com is the authority for my internal DNS zone), hence my Net::DNS requirement. Now, here is the IO module-specific information: What I am seeing is that the reply is coming back from the nameserver (confirmed via tcpdump – I can send the captures if you’d like), but the UDP packets are sitting in the process’s UDP receive queue pending reception by Net::DNS (the approx 1752 bytes per response stay queued waiting for $sel-can_read()): root@cwb-2-11:~# netstat -una Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State udp 1752 0 0.0.0.0:52680 0.0.0.0:* root@cwb-2-11:~# netstat -una Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State udp 5256 0 0.0.0.0:52680 0.0.0.0:* If I force $sock[AF_INET]-recv($buf, $self-_packetsz) around line 803 of /usr/lib/perl5/5.10/Net/DNS/Resolver/Base.pm, instead of waiting for IO::Select’s can_read() function ( @ready = $sel-can_read($timeout)) to populate @ready, the response is received and processed. Any idea what could be causing this issue? In a possibly related matter, I noticed in another script that the following code fails in the same manner (network responses stay in the process’s TCP receive queue) with the new system: $sock = new IO::Socket::INET( PeerAddr => "$server", PeerPort => 37, Proto => 'tcp', Timeout => 5 ); Whereas the following code works: $sock = new IO::Socket::INET( PeerAddr => "$server", PeerPort => 37, Proto => 'tcp' ); I have looked through the NET::DNS code and don’t see a timeout passed for the UDP sockets, so I am not sure if that this is related or not. Please let me know if I can provide you with any further information in order to help diagnose this issue. Thanks! -Rich

  • Action bar with Search View. Reverse compatibility issues

    - by suresh
    I am building a sample app to demonstrate SearchView with filter and other Action Bar items. I am able to successfully run this app on 4.2(Nexus 7). But it is not running on 2.3. I googled about the issue. Came to know that i should use SherLock Action bar. I just went to http://actionbarsherlock.com/download.html, downloaded the zip file and added the library as informed in the video: http://www.youtube.com/watch?v=4GJ6yY1lNNY&feature=player_embedde by WiseManDesigns. But still I am unable to figure out the issue. Here is my code: SearchViewActionBar.java public class SearchViewActionBar extends Activity implements SearchView.OnQueryTextListener { private SearchView mSearchView; private TextView mStatusView; int mSortMode = -1; private ListView mListView; private ArrayAdapter<String> mAdapter; protected CharSequence[] _options = { "Wild Life", "River", "Hill Station", "Temple", "Bird Sanctuary", "Hill", "Amusement Park"}; protected boolean[] _selections = new boolean[ _options.length ]; private final String[] mStrings = Cheeses.sCheeseStrings; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().requestFeature(Window.FEATURE_ACTION_BAR); setContentView(R.layout.activity_main); // mStatusView = (TextView) findViewById(R.id.status_text); // mSearchView = (SearchView) findViewById(R.id.search_view); mListView = (ListView) findViewById(R.id.list_view); mListView.setAdapter(mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mStrings)); mListView.setTextFilterEnabled(true); //setupSearchView(); } private void setupSearchView() { mSearchView.setIconifiedByDefault(true); mSearchView.setOnQueryTextListener(this); mSearchView.setSubmitButtonEnabled(false); //mSearchView.setQueryHint(getString(R.string.cheese_hunt_hint)); } @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.searchview_in_menu, menu); MenuItem searchItem = menu.findItem(R.id.action_search); mSearchView = (SearchView) searchItem.getActionView(); //setupSearchView(searchItem); setupSearchView(); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { if (mSortMode != -1) { Drawable icon = menu.findItem(mSortMode).getIcon(); menu.findItem(R.id.action_sort).setIcon(icon); } return super.onPrepareOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { String c="Category"; String s=(String) item.getTitle(); if(s.equals(c)) { System.out.println("same"); showDialog( 0 ); } //System.out.println(s); Toast.makeText(this, "Selected Item: " + item.getTitle(), Toast.LENGTH_SHORT).show(); return true; } protected Dialog onCreateDialog( int id ) { return new AlertDialog.Builder( this ) .setTitle( "Category" ) .setMultiChoiceItems( _options, _selections, new DialogSelectionClickHandler() ) .setPositiveButton( "SAVE", new DialogButtonClickHandler() ) .create(); } public class DialogSelectionClickHandler implements DialogInterface.OnMultiChoiceClickListener { public void onClick( DialogInterface dialog, int clicked, boolean selected ) { Log.i( "ME", _options[ clicked ] + " selected: " + selected ); } } public class DialogButtonClickHandler implements DialogInterface.OnClickListener { public void onClick( DialogInterface dialog, int clicked ) { switch( clicked ) { case DialogInterface.BUTTON_POSITIVE: printSelectedPlanets(); break; } } } protected void printSelectedPlanets() { for( int i = 0; i < _options.length; i++ ){ Log.i( "ME", _options[ i ] + " selected: " + _selections[i] ); } } public void onSort(MenuItem item) { mSortMode = item.getItemId(); invalidateOptionsMenu(); } public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText)) { mListView.clearTextFilter(); } else { mListView.setFilterText(newText.toString()); } return true; } public boolean onQueryTextSubmit(String query) { mStatusView.setText("Query = " + query + " : submitted"); return false; } public boolean onClose() { mStatusView.setText("Closed!"); return false; } protected boolean isAlwaysExpanded() { return false; } }

  • Link Error : xxx is already defined in *****.LIB :: What exactly is wrong?

    - by claws
    Problem: I'm trying to use a library named DCMTK which used some other external libraries ( zlib, libtiff, libpng, libxml2, libiconv ). I've downloaded these external libraries (*.LIB & *.h files ) from the same website. Now, when I compile the DCMTK library I'm getting link errors (793 errors) like this: Error 2 error LNK2005: __encode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 3 error LNK2005: __decode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 4 error LNK2005: __CrtSetCheckCount already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 5 error LNK2005: __invoke_watson already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 6 error LNK2005: __errno already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 7 error LNK2005: __configthreadlocale already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 8 error LNK2005: _exit already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Documentation: This seems to be a popular error for this library so, they do have a FAQ entry addressing this issue which ( http://forum.dcmtk.org/viewtopic.php?t=35 ) says: The problem is that the linker tries to combine different, incompatible versions of the Visual C++ runtime library into a single binary. This happens when not all parts of your project and the libraries you link against are generated with the same code generation options in Visual C++. Do not use the /NODEFAULTLIB workaround, because strange software crashes may follow. Fix the problem! DCMTK is by default compiled with the "Multithreaded" or "Multithreaded Debug" code generation option (the latter for Debug mode). Either change the project settings of all of your code to use these code generation options, or change the code generation for all DCMTK modules and re-compile. MFC users beware: DCMTK should be compiled with "Multithreaded DLL" or "Multithreaded DLL Debug" settings if you want to link the libraries into an MFC application. Solution to same problem for others: http://stackoverflow.com/questions/2259697/vscopengl-huge-amount-of-linker-issues-with-release-build-only says: It seems that your release build is trying to link to something that was built debug. You probably have a broken dependency in your build, (or you missed rebuilding something to release by hand if your project is normally built in pieces). More technically, you seem to be linking projects built with different C Run Time library settings, one with "Multi-Threaded", another one with "Multi-Threaded Debug". Adjust the settings for all the projects to use the very same flavour of the library and the issue should go away Questions: Till now I used to think that Name mangling is the only problem that may cause linking failures if its not been standardized. Just now I knew there are other things also which can cause same effect. Whats up with the "Debug Mode" (Multi-Threaded Debug) and "Release Mode" (Multi-Threaded)? What exactly is happening under the hood? Why exactly this thing is causing linking error? I wonder if there is something called "Single-Threaded Debug" and "Single-Threaded" which again causes the same thing. Documentation talks something about "Code Generation Options". What Code Generation Options? WTH are they? Documentation specifically warns us not to use /NODEFAULTLIB workaround. (example /NODEFAULTLIB :msvcrt ). Why? How would I cause troubles? what exactly is it? Please explain the last point in the documentation for MFC users. Because I'm going to use MFC later in this project. Explain Why should we do it? What troubles would it cause if I don't. Anything more you'd like to mention? I mean regarding similar errors. I'm very interested in Linker & its problems. So, if there are any similar things you can mentions them or some keywords atleast.

  • Trouble with datasource not being called from viewWillAppear

    - by user278859
    A little background. I have taken GCCalendar which only works in portrait orientation and extended it to work in landscape similar to how the iPhone's Calendar app works. I did this by duplicating the main view class and modifying it to work in landscape. So when the phone is in portrait orientation the CGCalendar is instantiated from the apps main view controller using the original portrait view class and when in landscape orientation using the new modified landscape view class. Most of the other classes in GCCalendar are shared without modification. A few had to be duplicated as well. I got it all working great except for an issue with the datasource. The datasource is called when the calendar is first loaded and each time the user changes the dates being viewed. Problem is I can't get the datasource call to work on the first call. I am stumped as it works fine in portrait orientation and I cannot find any difference between the 2 versions. Following is some of the code that shows how it gets to the datasource call the first time. Subsequent calls removes all the calendar subviews and instantiates them again with the new dates. The duplicated landscape class names end in LS. Otherwise as you can see they are identical. Does anyone has any idea of where else I might look to resolve this issue? Thanks, John -------------------------------- //App main view controller - (void)showLandscapeCalendar { GCCalendarLandscapeView *calendar = [[[GCCalendarLandscapeView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (void)showPortraitCalendar { GCCalendarPortraitView *calendar = [[[GCCalendarPortraitView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (NSArray *)calendarEventsForDate:(NSDate *)date{ //build and return the events array //this is the protocol datasource method //It is supposed to run every time the date changes in the calendar } ------------------------------- // GCCalendarLandscapeView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayViewLS *nextDayView = [[GCCalendarDayViewLS alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayViewLS - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { //** first time through the dataSource method does not run events = [dataSource calendarEventsForDate:date]; } ------------------------------- // GCCalendarPortraitView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayView *nextDayView = [[GCCalendarDayView alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayView - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { **//this one works every time events = [dataSource calendarEventsForDate:date]; }

    I'm using a combination of SDL and OpenGL in a sort of crash course project to teach myself how this all works. I'm really only interested in OpenGL as a way to use acceleration in 2D games so I just need this to work in a 2D plane. I have been having a lot of problems today with my current issue, I would like an object to point towards the mouse while the mouse button is clicked and then of course stay pointing in that direction after the mouse is lifted. void Square::handle_input() { //If a key was pressed if( event.type == SDL_KEYDOWN ) { //Adjust the velocity switch( event.key.keysym.sym ) { case SDLK_UP: upUp = false; yVel = -1; break; case SDLK_DOWN: downUp = false; yVel = 1; break; case SDLK_LEFT: leftUp = false; xVel = -1; break; case SDLK_RIGHT: rightUp = false; xVel = 1; break; case SDLK_w: wUp = false; sAng = 1; break; case SDLK_s: sUp = false; sAng = -1; break; } } //If a key was released else if( event.type == SDL_KEYUP ) { //Adjust the velocity switch( event.key.keysym.sym ) { case SDLK_UP: upUp = true; yVel = 0; break; case SDLK_DOWN: downUp = true; yVel = 0; break; case SDLK_LEFT: leftUp = true; xVel = 0; break; case SDLK_RIGHT: rightUp = true; xVel = 0; break; case SDLK_w: wUp = true; sAng = 0; break; case SDLK_s: sUp = true; sAng = 0; break; } } //If a mouse button was pressed if( event.type == SDL_MOUSEBUTTONDOWN ) { switch ( event.type ) { case SDL_MOUSEBUTTONDOWN: mouseUp = false; mousex == event.button.x; mousey == event.button.y; break; case SDL_MOUSEBUTTONUP: mouseUp = true; break; } } } And then this is called at the end of my Object::Move call which also handles x and y translation if (!mouseUp) { xVect = mousex - x; yVect = mousey - y; radAng = atan2 ( mousey - y, mousex - x ); sAng = radAng * 180 / 3.1415926l; } Right now when I click the object turns and faces down to the bottom left but then no longer changes direction. I'd really appreciate any help I could get here. I'm guessing there might be an issue here with state versus polled events but from all the tutorials that I've been through I was pretty sure I had fixed that. I've just hit a wall and I need some advice!

  • Languages and VMs: Features that are hard to optimize and why

    - by mrjoltcola
    I'm doing a survey of features in preparation for a research project. Name a mainstream language or language feature that is hard to optimize, and why the feature is or isn't worth the price paid, or instead, just debunk my theories below with anecdotal evidence. Before anyone flags this as subjective, I am asking for specific examples of languages or features, and ideas for optimization of these features, or important features that I haven't considered. Also, any references to implementations that prove my theories right or wrong. Top on my list of hard to optimize features and my theories (some of my theories are untested and are based on thought experiments): 1) Runtime method overloading (aka multi-method dispatch or signature based dispatch). Is it hard to optimize when combined with features that allow runtime recompilation or method addition. Or is it just hard, anyway? Call site caching is a common optimization for many runtime systems, but multi-methods add additional complexity as well as making it less practical to inline methods. 2) Type morphing / variants (aka value based typing as opposed to variable based) Traditional optimizations simply cannot be applied when you don't know if the type of someting can change in a basic block. Combined with multi-methods, inlining must be done carefully if at all, and probably only for a given threshold of size of the callee. ie. it is easy to consider inlining simple property fetches (getters / setters) but inlining complex methods may result in code bloat. The other issue is I cannot just assign a variant to a register and JIT it to the native instructions because I have to carry around the type info, or every variable needs 2 registers instead of 1. On IA-32 this is inconvenient, even if improved with x64's extra registers. This is probably my favorite feature of dynamic languages, as it simplifies so many things from the programmer's perspective. 3) First class continuations - There are multiple ways to implement them, and I have done so in both of the most common approaches, one being stack copying and the other as implementing the runtime to use continuation passing style, cactus stacks, copy-on-write stack frames, and garbage collection. First class continuations have resource management issues, ie. we must save everything, in case the continuation is resumed, and I'm not aware if any languages support leaving a continuation with "intent" (ie. "I am not coming back here, so you may discard this copy of the world"). Having programmed in the threading model and the contination model, I know both can accomplish the same thing, but continuations' elegance imposes considerable complexity on the runtime and also may affect cache efficienty (locality of stack changes more with use of continuations and co-routines). The other issue is they just don't map to hardware. Optimizing continuations is optimizing for the less-common case, and as we know, the common case should be fast, and the less-common cases should be correct. 4) Pointer arithmetic and ability to mask pointers (storing in integers, etc.) Had to throw this in, but I could actually live without this quite easily. My feelings are that many of the high-level features, particularly in dynamic languages just don't map to hardware. Microprocessor implementations have billions of dollars of research behind the optimizations on the chip, yet the choice of language feature(s) may marginalize many of these features (features like caching, aliasing top of stack to register, instruction parallelism, return address buffers, loop buffers and branch prediction). Macro-applications of micro-features don't necessarily pan out like some developers like to think, and implementing many languages in a VM ends up mapping native ops into function calls (ie. the more dynamic a language is the more we must lookup/cache at runtime, nothing can be assumed, so our instruction mix is made up of a higher percentage of non-local branching than traditional, statically compiled code) and the only thing we can really JIT well is expression evaluation of non-dynamic types and operations on constant or immediate types. It is my gut feeling that bytecode virtual machines and JIT cores are perhaps not always justified for certain languages because of this. I welcome your answers.

  • With NHibernate, how can I add a child object when updating a parent object?

    - by BMZ
    I have a simple Parent/Child relationship between a Person object and an Address object. The Person object exists in the DB. After doing a Get on the Person, I add a new Address object to the Address sub-object list of the parent, and do some other updates to the Person object. Finally, I do an Update on the Person object. With a SQL trace window, I can see the update to the Person object to the Person table and the Insert of the Address record to the Address table. The issue is that, after the update is performed, the AddressId (primary key on the Address object) is still set to 0, which is what it defaults to when you first initialize the Address object. I have verified that when I do an Add, this value is set correctly. Is this a known issue when trying to add sub-objects as part of an NHibernate UPDATE? Sample code and mapping files are below Thanks <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="BusinessEntities.Wellness.Person,BusinessEntities.Wellness" table="Person" lazy="true" dynamic-insert="true" dynamic-update="false"> <id name="Personid" column="PersonID" type="int"> <generator class="native" /> </id> <version type="binary" generated="always" name="RecordVersion" column="`RecordVersion`"/> <property type="int" not-null="true" name="Customerid" column="`CustomerID`" /> <property type="AnsiString" not-null="true" length="9" name="Ssn" column="`SSN`" /> <property type="AnsiString" not-null="true" length="30" name="FirstName" column="`FirstName`" /> <property type="AnsiString" not-null="true" length="35" name="LastName" column="`LastName`" /> <property type="AnsiString" length="1" name="MiddleInitial" column="`MiddleInitial`" /> <property type="DateTime" name="DateOfBirth" column="`DateOfBirth`" /> <bag name="PersonAddresses" inverse="true" lazy="true" cascade="all"> <key column="PersonID" /> <one-to-many class="BusinessEntities.Wellness.PersonAddress,BusinessEntities.Wellness" / </bag> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="BusinessEntities.Wellness.PersonAddress,BusinessEntities.Wellness" table="PersonAddress" lazy="true" dynamic-insert="true" dynamic-update="false"> <id name="PersonAddressId" column="PersonAddressID" type="int"> <generator class="native" /> </id> <version type="binary" generated="always" name="RecordVersion" column="`RecordVersion`" /> <property type="AnsiString" not-null="true" length="1" name="AddressTypeid" column="`AddressTypeID`" /> <property type="AnsiString" not-null="true" length="60" name="AddressLine1" column="`AddressLine1`" /> <property type="AnsiString" length="60" name="AddressLine2" column="`AddressLine2`" /> <property type="AnsiString" length="60" name="City" column="`City`" /> <property type="AnsiString" length="2" name="UsStateId" column="`USStateID`" /> <property type="AnsiString" length="5" name="UsPostalCodeId" column="`USPostalCodeID`" /> <many-to-one name="Person" cascade="none" column="PersonID" /> </class> </hibernate-mapping> Person newPerson = new Person(); newPerson.PersonName = "John Doe"; newPerson.SSN = "111111111"; newPerson.CreatedBy = "RJC"; newPerson.CreatedDate = DateTime.Today; personDao.AddPerson(newPerson); Person updatePerson = personDao.GetPerson(newPerson.PersonId); updatePerson.PersonAddresses = new List<PersonAddress>(); PersonAddress addr = new PersonAddress(); addr.AddressLine1 = "1 Main St"; addr.City = "Boston"; addr.State = "MA"; addr.Zip = "12345"; updatePerson.PersonAddresses.Add(addr); personDao.UpdatePerson(updatePerson); int addressID = updatePerson.PersonAddresses[0].AddressId;

  • A very strange problem related to Flash and Java

    - by Nitesh Panchal
    Hello, I have created one simple program for showing webcam of the user. It works absolutely fine when i am running without integrating it in my java web application. But as soon as i copy paste the same files in Netbeans 6.8 and try to run it. My swf file is visible but the buttons in it are totally unclickable. I get the message of allow or deny showing webcam but the buttons are not clickable. It makes my application totally useless. I thought it's a minor issue but now it's getting on my nerves. I am trying it since 3 hours but didn't find any solution. I don't think anybody faced this issue till now that's why can't seem to find any thread in any forum on it in google. I am using Netbeans 6.8, Ubuntu, Glassfish V3 and JSF. Thanks in advance :). UPDATE:- It works fine on Windows XP. Then what can be the problem with Ubuntu? Any kind of permission rights that i need to give? 2nd UPDATE:- I think this is bug with Flash. I found that this code doesn't work :- <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0" id="VideoConferenceAdmin" align="middle"> <param name="allowScriptAccess" value="sameDomain" /> <param name="wmode" value="opaque"/> <param name="allowFullScreen" value="false" /> <param NAME="FlashVars" VALUE="rootIp=localhost&amp;userName=admin&amp;roomName=test" /> <param name="movie" value="Conference/VideoConference.swf" /><param name="quality" value="high" /> <embed src="Conference/VideoConference.swf" wmode="window" FlashVars="rootIp=localhost&amp;userName=test&amp;roomName=test" quality="high" width="600" height="500" name="VideoConference" align="middle" allowScriptAccess="sameDomain" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /> </object> And this one works :- <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0" id="VideoConferenceAdmin" align="middle"> <param name="allowScriptAccess" value="sameDomain" /> <param name="wmode" value="opaque"/> <param name="allowFullScreen" value="false" /> <param NAME="FlashVars" VALUE="rootIp=localhost&amp;userName=admin&amp;roomName=test" /> <param name="movie" value="Conference/VideoConference.swf" /><param name="quality" value="high" /> <embed src="Conference/VideoConference.swf" wmode="window" FlashVars="rootIp=localhost&amp;userName=test&amp;roomName=test" quality="high" name="VideoConference" align="middle" allowScriptAccess="sameDomain" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /> </object> As you can see, just by removing the height and width attribute the panels of Flash settings work fine. I know you will find me funny but i am not. You can check out on your own if you don't trust me. Now, my question would be, can anybody tell me how do i set height and width of swf? I want it to be 600px width and 500px height. Even the style attribute doesn't work. Can i set height and width from within Flash? because without explicitly setting height and width, it looks very small. I think this should be very easy for all now. Thanks in advance :)

  • ASP.Net/C# File Upload Progress Display

    - by Ioxp
    I am having a hard time figuring out how to do a "Please wait while file is uploading" message when the user submits the following form. So far the application works to specification with regards to checking files and uploading to the server. You will see some java script below, this is there to allow me to fake out the style of the file up load buttons so that it matches the rest of the site. I have tried to use the ASP.Net Ajax controls to do this however the updateprogress panel would not show up. In further reading it was explained that this has something to do with the Asynchronous transfer that the file upload control uses when you issue a PostedFile.SaveAs("filename") command. I also found a site that refereed to using an iframe to do the job. I'm not really sure if that's the best way to go about doing this or not so I'm asking you the professionals of stackoverflow for help to try and resolve this issue. I will be more than happy to post any spinets you need from my code to help me expedite a solution for this. <table border="0"> <tr> <td>File 1:&nbsp;</td> <td><div class="fileinputs"><input type="file" class="file" size="37" id="f1" runat="server" /></div></td> </tr> <tr> <td>File 2:&nbsp;</td> <td><div class="fileinputs"><input type="file" class="file" size="37" id="f2" runat="server" /></div></td> </tr> <tr> <td colspan="2" style="text-align:right;"><asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/Images/Buttons/Upload_Files.gif" OnClick="Submit_Form" /></td> </tr> </table> <asp:Label ID="lblError" runat="server" Text=""></asp:Label> <script type="text/javascript"> var fakeFileUpload = document.createElement('div'); fakeFileUpload.className = 'fakefile'; var fakeInput = document.createElement('input'); fakeInput.style.width = '200px'; fakeFileUpload.appendChild(fakeInput); var image = document.createElement('img'); image.src='../Images/Buttons/Browse.gif'; fakeFileUpload.appendChild(image); var x = document.getElementsByTagName('input'); for (var i=0;i<x.length;i++) { if (x[i].type != 'file') continue; if (x[i].parentNode.className != 'fileinputs') continue; x[i].className = 'file hidden'; var clone = fakeFileUpload.cloneNode(true); x[i].parentNode.appendChild(clone); x[i].relatedElement = clone.getElementsByTagName('input')[0]; x[i].onchange = x[i].onmouseout = function () { this.relatedElement.value = this.value; } } </script>

  • ActionScript Gradient Banding Problem

    - by TheDarkIn1978
    i'm having a strange issue with banding between certain colors of a gradient. to create the gradient, i'm drawing evenly spaced circle wedges from the center to the border, and filling each circle wedge from a bitmap line gradient pixel in a loop. public class ColorWheel extends Sprite { private static const DEFAULT_RADIUS:Number = 100; private static const DEFAULT_BANDING_QUALITY:int = 3600; public function ColorWheel(nRadius:Number = DEFAULT_RADIUS) { init(nRadius); } public function init(nRadius:Number = DEFAULT_RADIUS):void { var nRadians : Number; var nColor : Number; var objMatrix : Matrix = new Matrix(); var nX : Number; var nY : Number; var previousX : Number = nRadius; var previousY : Number = 0; var leftToRightColors:Array = new Array(0xFF0000, 0xFFFF00, 0x00FF00, 0x00FFFF, 0x0000FF, 0xFF00FF); leftToRightColors.push(leftToRightColors[0]); var leftToRightAlphas:Array = new Array(); var leftToRightRatios:Array = new Array(); var leftToRightPartition:Number = 255 / (leftToRightColors.length - 1); //Push arrays for (var j:int = 0; j < leftToRightColors.length; j++) { leftToRightAlphas.push(1); leftToRightRatios.push(j * leftToRightPartition); } var leftToRightColorsMatrix:Matrix = new Matrix(); leftToRightColorsMatrix.createGradientBox(DEFAULT_BANDING_QUALITY, 1); //Produce a horizontal leftToRightLine sprite var leftToRightLine:Sprite = new Sprite(); leftToRightLine.graphics.lineStyle(1, 0, 1, false, LineScaleMode.NONE, CapsStyle.NONE); leftToRightLine.graphics.lineGradientStyle(GradientType.LINEAR, leftToRightColors, leftToRightAlphas, leftToRightRatios, leftToRightColorsMatrix); leftToRightLine.graphics.moveTo(0, 0); leftToRightLine.graphics.lineTo(DEFAULT_BANDING_QUALITY, 0); //Assign bitmapData to the leftToRightLine var leftToRightLineBitmapData:BitmapData = new BitmapData(leftToRightLine.width, leftToRightLine.height); leftToRightLineBitmapData.draw(leftToRightLine); for(var i:int = 1; i < (DEFAULT_BANDING_QUALITY + 1); i++) { // Convert the degree to radians. nRadians = i * (Math.PI / (DEFAULT_BANDING_QUALITY / 2)); // OR the individual color channels together. nColor = leftToRightLineBitmapData.getPixel(i-1, 0); // Calculate the coordinate in which the line should be drawn to. nX = nRadius * Math.cos(nRadians); nY = nRadius * Math.sin(nRadians); // Create a matrix for the wedges gradient color. objMatrix.createGradientBox(nRadius * 2, nRadius * 2, nRadians, -nRadius, -nRadius); graphics.beginGradientFill(GradientType.LINEAR, [nColor, nColor], [1, 1], [127, 255], objMatrix); graphics.moveTo( 0, 0 ); graphics.lineTo( previousX, previousY ); graphics.lineTo( nX, nY ); graphics.lineTo( 0, 0 ); graphics.endFill(); previousX = nX; previousY = nY; } } } i'm creating a circle with 3600 wedges, although it doesn't look like it based on the screen shot within the orange color that is produced from gradating from red to yellow numbers. adding a orange number between red and yellow doesn't help. but if i create the circle with only 360 wedges, the gradient banding is much more obvious. 3600 is probably overkill, and doesn't really add more detail over, say, making the circle of 1440 wedges, but i don't know any other way to slightly elevate this banding issue. any ideas how i can fix this, or what i'm doing wrong? could it be caused by the circleMatrix rotation?

  • Using resize to getScript if above x pixels (jQuery)

    - by user1065573
    So I have an issue with this script. It basically is loading the script on any resize event. I have it working if lets say... - User has window size above 768 (getScipt() and content by .load() in that script) - Script will load (and content) - User for some reason window size goes below 768 (css hides #div) - User re-sizes again above 768, And does not load the script again! (css displays the div) Great. Works right. Now.. (for some cray reason) - User has window size below 768 (Does NOT getScript() or nothing) - User re-sizes above 768 and stops at any px (getScript and content) - User re-sizes again anything above 768 (It getScript AGAIN) I need it to only get script once. Ive used some code from here jQuery: How to detect window width on the fly? (edit - i found this, which he has the same issue of loading a script once.) Problem with function within $(window).resize - using jQuery And others i lost the links to :/ When i first found this problem I was using something like this, then i added the allcheckWidth() to solve problem. But it does not. var $window = $(window); function checkWidth() { var windowsize = $window.width(); ////// LETS GET SOME THINGS IF IS DESKTOP var $desktop_load = 0; if (windowsize >= 768) { if (!$desktop_load) { // GET DESKTOP SCRIPT TO KEEP THINGS QUICK $.getScript("js/desktop.js", function() { $desktop_load = 1; }); } else { } } ////// LETS GET SOME THINGS IF IS MOBILE if (windowsize < 768) { } } checkWidth(); function allcheckWidth () { var windowsize = $window.width(); //// IF WINDOW SIZE LOADS < 768 THEN CHANGES >= 768 LOAD ONCE var $desktop_load = 0; if (!$desktop_load) { if (windowsize < 768) { if ( $(window).width() >= 768) { $.getScript("js/desktop.js", function() { $desktop_load = 1; }); } } } } $(window).resize(allcheckWidth); Now im using something like this which makes more sense? $(function() { $(window).resize(function() { var $desktop_load = 0; //Dekstop if (window.innerWidth >= 768) { if (!$desktop_load) { // GET DESKTOP SCRIPT TO KEEP THINGS QUICK $.getScript("js/desktop.js", function() { $desktop_load + 1; }); } else { } } if (window.innerWidth < 768) { if (window.innerWidth >= 768) { if (!$desktop_load) { // GET DESKTOP SCRIPT TO KEEP THINGS QUICK $.getScript("js/desktop.js", function() { $desktop_load + 1; }); } else { } } } }) .resize(); // trigger resize event }) Ty for future response. Edit - To give an example, in desktop.js i have a gif that loads before "abc" content, that gets inserted by .load(). On resize this gif will show up and the .load() in desktop.js will fire again. So if getScript was only being called once, it should not be doing anything again in desktop.js. Confusing?

  • Calling Object Methods in Code

    - by Mister R2
    I'm a bit new to PHP, and I'm more experienced with strongly-typed languages such as JAVA, C# or C++.I'm currently writing a web tool in PHP, and I am having an issue trying to do what I want. The simple idea of what I want to do in code is run through some emails I used PHP-IMAP to get. I then create email objects (a class I defined), and put them in an array. Later on the code, however, I cycle through those emails to display them. However, as you might have guessed I'd have an issue with, I try to use an Email Class object method in that later loop -- and I'm pretty sure PHP doesn't know that the variables in the array happen to be Email Class objects! I wrote a toString method, and I want to call it in the loop. While I don't need to do this for the final version of this tool, I would like to find out what I'm missing. This is the class and the loop where I'm calling the method: include 'imap_email_interface.php'; class ImapEmail implements imap_email_interface { // Email data var $msgno; var $to; var $from; var $subject; var $body; var $attachment; // Email behavior /* PHP 4 ~ legacy constructor */ public function ImapEmail($message_number) { $this->__construct(); $this->msgno = $message_number; } /* PHP 5 Constructor */ public function __construct($message_number) { $this->msgno = $message_number; } public function send($send_to) { // Not Yet Needed! Seriously! } public function setHeaderDirectly($TO, $FROM, $SUBJECT) { $this->to = $TO; $this->from = $FROM; $this->subject = $SUBJECT; } public function setHeaderIndirectly($HEADER) { if (isset($HEADER->to[0]->personal)) $this->to = '"'.$HEADER->to[0]->personal.'", '.$HEADER->to[0]->mailbox.'@'.$HEADER->to[0]->host; else $this->to = $HEADER->to[0]->mailbox.'@'.$HEADER->to[0]->host; $this->from = '"'.$HEADER->from[0]->personal.'", '.$HEADER->from[0]->mailbox.'@'.$HEADER->from[0]->host; $this->subject = $HEADER->subject; } public function setBody($BODY) { $this->body = $BODY; } public function setAttachment($ATTCH) { $this->attachment = $ATTCH; } public function toString() { $str = '[TO]: ' . $this->to . '<br />' . '[FROM]: ' . $this->from . '<br />' . '[SUBJECT]: ' . $this->subject . '<br />'; $str .= '[Attachment]: '.$this->attachment.'<br />'; return $str; } } ?> The Loop: foreach ($orderFileEmails as $x) { $x->toString(); echo '<br /><br />'; } Any ideas?
