• Eclipse PDT "tips" ?

  - by Pascal MARTIN

  Hi ! (Yes, this is a quite opened and general and subjective question -- it's by design, cause I want tips you think are great !) I'm using Eclipse PDT 2.1 to work in PHP, either for small and/or big projects -- I've been doing so for quite some times, now, actually (since before 1.0 stable, if I remember well)... I was wondering if any of you did know "tips" to be more efficient. Let met explain more in details : I know about things like plugins like Aptana (better editor for JS/CSS), Subversive (for SVN access), RSE, Filesync, integrating Xdebug's debugger, ... What I mean by "tips" is more some little things you discovered one day and since use all the time -- and allow you to be more efficient in your PHP projects. Some examples of "tips" that come to my mind, and that already know and use : ctrl+space to open the list of suggestions for functions / variables names ctrl+shift+R (navigate > open resource) to open a popup which show only files which names contain what you type ; ie, quick opening of files this one might be the perfect example : I know this one is not often known by coworkers and they find it as useful as I do ; so, I guess there might be lots of other things like this one I don't know myself ^^ ctrl+M to switch to full-screen view for the editor (instead of double-click on tabs bar) shift+F2 while on a function name, to open it's page if the PHP manual in a browser Attention Mac Users use Command instead Control. I guess you get the point ; but I'm really open to any suggestion (be it eclipse-related in general, of more PHP/PDT-specific) that can help be be more efficient :-) Anyway, thanks in advance for your help !

• White Screen of Death (WSOD) in Browser

  - by nickyt

  Here's the specs: ASP.NET 3.5 using ASP.NET AJAX AJAX Control Toolkit jQuery 1.3.2 web services IIS6 on Windows Server 2003 SP1 SP1 SQLServer 2005 SP3 Site is SSL Here's the problem: I'm getting the White Screen of Death (WSOD) in pretty much any browser (at least FireFox and IE 7/8). We have an application that uses one popup window for updating records. Most of the time when you click on the [Edit] button to edit a record, the popup window opens and loads the update page. However, after editing records for a while, all of a sudden the popup window will open, but it stays blank and just hangs. The URL is in the address bar. Loading up Fiddler I noticed that the request for the update page is never sent which leads me to believe it's some kind of lockup on the client-side. If I copy the same URL that's in the popup window into a new browser window, the page generally loads fine. Observations: - Since the request is never sent to the server, it's definitely something client-side - Only appears to happen when there is some semblance of traffic on the site which is weird because this appears to be contained within client-side code - There is a web service being called in the background every few seconds checking if the user is logged on, but this doesn't cause the freeze. I'm really at a loss here. I've googled WSOD but not much seems to appear related to my specific WSOD. Any ideas?

• How to extract byte-array from one xml and store it in another in Java

  - by grobartn

  So I am using DocumentBuilderFactory and DocumentBuilder to parse an xml. So it is DOM parser. But what I am trying to do is extract byte-array data (its an image encoded in base64) Store it in one object and later in code write it out to another xml encoded in base64. What is the best way to store this in btw. Store it as string? or as ByteArray? How can I extract byte array data in best way and write it out. I am not experienced with this so wanted to get opinion from the group. UPDATE: I am given XML I do not have control of incoming XML that comes in binary64 encoded < byte-array > ... base64 encoded image ... < /byte-array > Using parser I have I need to store this node and question is should that be byte or string and then writing it out to another node in new xml. again in base64 encoding. thanks

• Javascript not working in firefox

  - by Samuel Meddows

  Hi guys, I have a PHP form validation function that I developed in chrome and now will not work in firefox or Opera. The function checks to see if a section of the form is blank and shows and error message. If there is no error then then the form submits through document.events.submit(); CODE: function submit_events() { //Check to see if a number is entered if the corosponding textbox is checked if (document.events.dj_card.checked == true && dj_amount.value==""){ //Error Control Method //alert ('You didn\'t enetr an Amount for DJ\'s Card!'); var txt=document.getElementById("error") txt.innerHTML="<p><font color=\"#FF0000\"> You didn\'t enetr an Amount for DJ\'s Card!</font></p>"; window.document.getElementById("dj_card_label").style.color = '#FF0000'; //Reset window.document.getElementById("company_amount_label").style.color = '#000000'; window.document.getElementById("own_amount_label").style.color = '#000000'; }else{ document.events.submit(); } The document.events.submit();does work across all my browsers however the check statements do not. If the box is not ticked the form submits. If the box is ticked it does not matter whether there is data in the dj_amount.value or not. The form will not submit and no error messages are displayed. Thanks guys.

• WCF cross-domain policy security error

  - by George2

  Hello everyone, I am using VSTS 2008 + C# + WCF + .Net 3.5 + Silverlight 3.0. I host Silverlight control in an html page and debug it from VSTS 2008 (press F5, then run in VSTS 2008 built-in ASP.Net development web server), then call another WCF service (hosted in another machine running IIS 7.0 + Vista). The WCF service is very simple, just return a constant string to client. When invoking the WCF service from Silverlight, I got the following error message, An error occurred while trying to make a request to URI 'https://LabTest/Test.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. Here is the clientaccesspolicy.xml file, anything wrong? <?xml version="1.0" encoding="utf-8" ?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*"> </domain> </allow-from> <grant-to> <resource path="/" include-subpaths="true"></resource> </grant-to> </policy> </cross-domain-access> </access-policy> thanks in advance, George

• What database strategy to choose for a large web application

  - by Snoopy

  I have to rewrite a large database application, running on 32 servers. The hardware is up to date, each machine has two quad core Xeon and 32 GByte RAM. The database is multi-tenant, each customer has his own file, around 5 to 10 GByte each. I run around 50 databases on this hardware. The app is open to the web, so I have no control on the load. There are no really complex queries, so SQL is not required if there is a better solution. The databases get updated via FTP every day at midnight. The database is read-only. C# is my favourite language and I want to use ASP.NET MVC. I thought about the following options: Use two big SQL servers running SQL Server 2012 to serve the 32 servers with data. On the 32 servers running IIS hosting providing REST services. Denormalize the database and use Redis on each webserver. Use booksleeve as a Redis client. Use a combination of SQL Server and Redis Use SQL Server 2012 together with Hadoop Use Hadoop without SQL Server What is the best way for a read-only database, to get the best performance without loosing maintainability? Does Map-Reduce make sense at all in such a scenario? The reason for the rewrite is, the old app written in C++ with ISAM technology is too slow, the interfaces are old fashioned and not nice to use from an website, especially when using ajax. The app uses a relational datamodel with many tables, but it is possible to write one accerlerator table where all queries can be performed on, and all other information from the other tables are possible by a simple key lookup.

• Populate a column as a result of performing math on two columns in a jqGrid.

  - by HacksawOnRye

  Background: Our company selected a workflow tool that has some "interersting" UI restrictions. jqGrid has been identified as one of best ways to overcome these restrictions. Consequently, the answers to this question need to be restricted to functionlity available within the jqGrid space. It pains me to pose this question and I know you will tempted to go down a million other paths - most that we have already traveled before. :( Question: Can jqGrid populate a column as a result of performing math on two other columns. The source of those two columns is in our control so we can "guarantee" that numeric data will be returned. Also, the result is something that we simplay want to display on demand but not store yet. On the example below, is there a function that allow the 'total' column to be populated from the following calculation: 'amount' * 'tax' Example jqGrid javascript: jQuery("#list3").jqGrid({ url:'server.php?q=2', datatype: "json", colNames:['Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'], colModel:[ {name:'id',index:'id', width:60, sorttype:"int"}, {name:'invdate',index:'invdate', width:90, sorttype:"date"}, {name:'name',index:'name', width:100}, {name:'amount',index:'amount', width:80, align:"right",sorttype:"float"}, {name:'tax',index:'tax', width:80, align:"right",sorttype:"float"}, {name:'total',index:'total', width:80,align:"right",sorttype:"float"}, {name:'note',index:'note', width:150, sortable:false} ], rowNum:20, rowList:[10,20,30], pager: '#pager3', sortname: 'id', viewrecords: true, sortorder: "desc", loadonce: true, caption: "Load Once Example" });

• Dynamic TextBox on LinkButton click

  - by Alex Peta

  I am creating dynamic TextBoxes in a page by clicking a LinkButton. However, after that, if the page is submitted, I can't find the items created dynamically, thus, can't send the information to the database. protected void lbAddTag_Click(object sender, EventArgs e) { for (int i = 0; i < 3;i++ ) { CreateTextBox("txtTag-" + i.ToString()); } } private void CreateTextBox(string ID) { TextBox txt = new TextBox(); txt.ID = ID; txt.Width = Unit.Pixel(300); //txt.TextChanged += new EventHandler(OnTextChanged); txt.AutoPostBack = false; tagsPanel.Controls.Add(txt); Literal lt = new Literal(); lt.Text = "<br /><br />"; tagsPanel.Controls.Add(lt); } If I put: foreach (Control c in tagsPanel.Controls) { if (c is TextBox) { lblError.Text += c.ClientID + " , "; } } in the lbAddTag_Click method I can see the items, and they exist, but if I submit the page and try to insert the values in the database nothing... Any hint is much appreciated.

• Testing a method used from an abstract class

  - by Bas

  I have to Unit Test a method (runMethod()) that uses a method from an inhereted abstract class to create a boolean. The method in the abstract class uses XmlDocuments and nodes to retrieve information. The code looks somewhat like this (and this is extremely simplified, but it states my problem) namespace AbstractTestExample { public abstract class AbstractExample { public string propertyValues; protected XmlNode propertyValuesXML; protected string getProperty(string propertyName) { XmlDocument doc = new XmlDocument(); doc.Load(new System.IO.StringReader(propertyValues)); propertyValuesXML= doc.FirstChild; XmlNode node = propertyValuesXML.SelectSingleNode(String.Format("property[name='{0}']/value", propertyName)); return node.InnerText; } } public class AbstractInheret : AbstractExample { public void runMethod() { bool addIfContains = (getProperty("AddIfContains") == null || getProperty("AddIfContains") == "True"); //Do something with boolean } } } So, the code wants to get a property from a created XmlDocument and uses it to form the result to a boolean. Now my question is, what is the best solution to make sure I have control over the booleans result behaviour. I'm using Moq for possible mocking. I know this code example is probably a bit fuzzy, but it's the best I could show. Hope you guys can help.

• Pass scalar/list context to called subroutine

  - by Will

  I'm trying to write a sub that takes a coderef parameter. My sub does some initialization, calls the coderef, then does some cleanup. I need to call the coderef using the same context (scalar, list, void context) that my sub was called in. The only way I can think of is something like this: sub perform { my ($self, $code) = @_; # do some initialization... my @ret; my $ret; if (not defined wantarray) { $code->(); } elsif (wantarray) { @ret = $code->(); } else { $ret = $code->(); } # do some cleanup... if (not defined wantarray) { return; } elsif (wantarray) { return @ret; } else { return $ret; } } Obviously there's a good deal of redundancy in this code. Is there any way to reduce or eliminate any of this redundancy? EDIT   I later realized that I need to run $code->() in an eval block so that the cleanup runs even if the code dies. Adding eval support, and combining the suggestions of user502515 and cjm, here's what I've come up with. sub perform { my ($self, $code) = @_; # do some initialization... my $w = wantarray; return sub { my $error = $@; # do some cleanup... die $error if $error; # propagate exception return $w ? @_ : $_[0]; }->(eval { $w ? $code->() : scalar($code->()) }); } This gets rid of the redundancy, though unfortunately now the control flow is a little harder to follow.

• Changing property of ItemTemplate controls in ListView

  - by arturito

  I have ListView containig LinkButtons in ItemTemplate. ListView is inside UpdatePanel so it is not doing page refresh. When users click on one the LinkButtons it changes its css property in order to mark the selection: protected void ListView1_ItemCommand1(object sender, ListViewCommandEventArgs e) { ((LinkButton)e.CommandSource).CssClass = "selected"; } That allows multiple selections. But once the page is refreshed the selection disappears, meaning that css property of control goes back to default. <ItemTemplate> <asp:LinkButton ID="local" Text='<%#Eval("Local.Name")%>' runat="server" CommandName="selectLocal" CommandArgument='<%#Eval("Local.Id") %>' CssClass="notSelected" > </asp:LinkButton> <asp:LinkButton ID="guest" Text='<%#Eval("Guest.Name")%>' runat="server" CommandName="selectGuest" CommandArgument='<%#Eval("Guest.Id") %>' CssClass="notSelected" > </asp:LinkButton> </ItemTemplate> How can I select them programatically on page reload? (I'm mainating selection list in session)

• Tfs 2010: how to set up a corporate source server?

  - by bwerks

  Hi all, I'm looking for guidance in setting up a corporate source server, but when I google this topic the best I can come up with is articles and walkthrough concerned with configuring VS to use microsoft's public symbol servers for use with debugging .NET assemblies. Provided for background info, the environment I'm concerned with using is Vs2010/Tfs2010. Basically, the workflow I'm looking to facilitate is this: 1) customer reports problem with application 2) application of the appropriate version is installed on a virtual machine 3) developer repros bug attaching to process on virtual machine and leveraging source server (symbol server?) on corporate domain. This is the step I'm concerned with. 4) developer pinpoints problem fixes bug in workspace. 5) developer performs a dll swap on VM to test changes? (side topic, not sure on this) 6) normal development/source control workflows. Any advice is welcome! Edit: since writing this, I have stumbled on this article, which is a nice writeup on the configuration of source server for TFS 2008. Has anyone adapted this for Tfs 2010?

• Auto increment with a Unit Of Work

  - by Derick

  Context I'm building a persistence layer to abstract different types of databases that I'll be needing. On the relational part I have mySQL, Oracle and PostgreSQL. Let's take the following simplified MySQL tables: CREATE TABLE Contact ( ID varchar(15), NAME varchar(30) ); CREATE TABLE Address ( ID varchar(15), CONTACT_ID varchar(15), NAME varchar(50) ); I use code to generate system specific alpha numeric unique ID's fitting 15 chars in this case. Thus, if I insert a Contact record with it's Addresses I have my generated Contact.ID and Address.CONTACT_IDs before committing. I've created a Unit of Work (amongst others) as per Martin Fowler's patterns to add transaction support. I'm using a key based Identity Map in the UoW to track the changed records in memory. It works like a charm for the scenario above, all pretty standard stuff so far. The question scenario comes in when I have a database that is not under my control and the ID fields are auto-increment (or in Oracle sequences). In this case I do not have the db generated Contact.ID beforehand, so when I create my Address I do not have a value for Address.CONTACT_ID. The transaction has not been started on the DB session since all is kept in the Identity Map in memory. Question: What is a good approach to address this? (Avoiding unnecessary db round trips) Some ideas: Retrieve the last ID: I can do a call to the database to retrieve the last Id like: SELECT Auto_increment FROM information_schema.tables WHERE table_name='Contact'; But this is MySQL specific and probably something similar can be done for the other databases. If do this then would need to do the 1st insert, get the ID and then update the children (Address.CONTACT_IDs) – all in the current transaction context.

• Soap 1.2 Endpoint Performance

  I have a Client WCF Host Service SOAP 1.2 Service setup and i'm having performance issues on the SOAP Java proxy. I have no control over how the Java service is setup, aside from the endpoint config. I have the Client running Asynchronously, and the host WCF service running in Async pattern, but i see the SOAP 1.2 proxy bottlenecking and handling the requests in a Synchronous way.

• Problem in getting response from server in jquery

  - by Alvin

  Hello, I'm using $.ajax(options) method to pass the request to server based on username and password, but whenever I try to print the response by XMLHttpRequest object when response gets successful, I'm getting an empty value. $(document).ready(function(){ $("#form").submit(function(){ $.ajax({url:"Chat.jsp",type:"POST",data:$("#form").serialize(),success:function(request) { alert(request.responseText); //This is displaying nothing },error:function(){document.write("YOU can't");}}); }); }); This is what I'm doing in my servlets code after executing query: try { String user = request.getParameter("j_username"); String password = request.getParameter("j_password"); if(user != null && password != null) { String query = "Select * from users where user_name="+"\'"+user+"\'"+"&& user_pass="+"\""+password+"\""; DBCheck db= new DBCheck(); boolean b = db.doExecuteQuery(con.createStatement(),query); response.setHeader("Cache-Control", "no-cache"); if(b) { response.getWriter().println("Username already exits"); } else { response.getWriter().println("Username doesn't exit"); } } } catch(SQLException ex) { ex.printStackTrace(); } } May I know the problem, and how can I fix it?

• URL protocol handler shell execute problem

  - by Chuck

  Hi, I'm working on a small hobby web site where I'm able to launch a local app with certain arguments based on links. Setting up a protocol wasn't difficult, as described in http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx, but I have one dilemma: Let's say the protocol is: foo:127.0.0.1:1111, so a link like href="foo:127.0.0.1:1111" would launch an app like: bar.exe "%1". Since I don't have any control over bar.exe (if I had, then it would be no problem to just parse it, obviously), I need some help parsing %1. bar.exe will launch correctly if it's run as bar.exe 127.0.0.1:1111, but not if it's run as bar.exe foo:127.0.0.1:1111. So I guess my question is... is there ANY way to tell the registry to pass on not %1, but a trimmed %1? (Thinking in terms of regexp where you have match[0] = all of the matched, match[1] = first capture in the matched text). I can solve it by having a .bat instead of .exe, but as I would like to make it as easy as possible for the user to use, I would LOVE it if I could handle it all stricly in registry. Any help is greatly appreciated! Chuck

• Copying a foreign Subversion repository to keep under dependencies

  - by Jonathan Sternberg

  I want to keep dependencies for my project in our own repository, that way we have consistent libraries for the entire team to work with. For example, I want our project to use the Boost libraries. I've seen this done in the past with putting dependencies under a "vendor" or "dependencies" folder. But I still want to be able to update these dependencies. If a new feature appears in a library and we need it, I want to just be able to update that repository within our own repository. I don't want to have to recopy it and put it under version control again. I'd also like for us to have the ability to change dependencies if a small change is needed without stopping us from ever updating the library. I want the ability to do something like 'svn cp', then be able to 'svn merge' in the future. I just tried this with the boost trunk, but I'm not able to get any history using 'svn log' on the copy I made. How do I do this? What is usually done for large projects with dependencies?

• Is there a best practice for concatenating MP3 Files, adjusting sample rates to match, while preserving original files?

  - by Scott

  Hello overflow community! Does anyone know if there is a "best practice" to concatenate mp3 files to create new files, while preserving the original files? I am working on a CentOS Linux machine, in command line. I will eventually call the command line from a PHP script. I have been doing research and I have come up with a process that I think could work. It combines general advice from different forums, blogs, and sources like this one. So here I go: Create a temporary folder Loop through files to create a new, converted copy, of file into a "raw" format (which one, I don't know. I didn't know "raw" files existed before too long ago. I could use some suggestions on this) Store the path to the temporary files, in the temporary folder, and then loop through the files to concatenate them and then put the new merged file the final "processed directory" Delete the contents of the temporary file with the temporary raw files inside. Convert the final file from "raw" to mp3 and enjoy the finished result I'm thinking that this course of action might be best because I can't necessarily control the quality of the original "source" mp3s. The only other option I could think of would be to create a script that would perform a similar process upon files being added to the system leaving only the files with the "proper" format and removing the original "erroneous" file. Hopefully you can see that I have put some thought into this and that I'm trying to leverage the collective knowledge of this community to choose the best direction. Perhaps there is a better path that I could take? By concatenate, I mean to join together in sequence to create a new audio file from the "concatenated files."

• Visual Studio / Blend... how you organize that?

  - by TomTom

  Virst time more complex stuff in WPF. I am a little lost on the split betwen VS and Blend. It seems I am VERY limited with editors in Visual Studio for editing controls - when customizing, for example, it seems I Can enter astyle in XML... but in blend I Can tell it to make a copy of the CURRENT style and use that as a starter, definitely more convenient. I understand the "difference in focus", but it seems to me that i Really need both tools to work, especially if the controls I Do are: More complex Not user controls "on purpose" (to allow more customization by programmes using the application). THis means when I do a control, my approach would be: Work on the backend as good as it gets without front end (i.e. implement all methods needed etc., but can be dummies) Switch over to Blend (closing visual studio - as the projcet must be closed) Put in the initial templating Switch over to VIsual Studio (closing blend) Put logic in and debug. This seems pretty counterintuitively. Am I missing something obvious here?

• WebView and HTML5 <video>

  - by brian moore

  I'm piecing together a cheapo app that amongst other things "frames" some of our websites... Pretty simple with the WebViewClient... until I hit the video. The video is done as HTML5 elements, and these work fine and dandy on Chrome, iPhones, and now that we fixed the encoding issues it works great on Android... in the native browser. Now the rub: WebView doesn't like it. At all. I can click on the poster image, and nothing happens. Googling, I found http://www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/ which is close, but seems to be based on a 'link' (as in a href...) instead of a video element. (onDownloadListener does not appear to get invoked on video elements...) I also see references to overriding onShowCustomView, but that seems to not get called on video elements... nor does shouldOverrideUrlLoading.. I would rather not get into "pull xml from the server, reformat it in the app".. by keeping the story layout on the server, I can control the content a bit better without forcing people to keep updating an app. So if I can convince WebView to handle tags like the native browser, that would be best. I'm clearly missing something obvious.. but I have no clue what.

• dynamically created controls and postback

  - by Mark

  Hi all, I have created dynamic controls (Radiobuttonlists) in an asp.net page (c#). I create them after a button click like this. RadioButtonList rbl = new RadioButtonList(); c2.Controls.Add(rbl); //Set properties of rbl rbl.RepeatLayout = RepeatLayout.Flow; rbl.ID = string.Format("rbl{0}", item.QuestionID); rbl.RepeatDirection = RepeatDirection.Horizontal; rbl.Items.Add(new ListItem("True", "1")); rbl.Items.Add(new ListItem("False", "0")); rbl.Items.Add(new ListItem("?", "-1")); Now the problem arises when I click the submit button, the controls are lost. I know it's better to actually put the controls in page_init event. but is there no workaround so I can still initiate my controls after button click? And is it good to first create button, then add it to control collection and then set its properties? Thankd in advance Kind regards, Mark

• Need an Overview of Possibilities for multicolumn programming

  - by Sam

  Hi folks, From source1 and source2 i gather that IE9 will NOT support multi-column css3!! Since it is still the most popular browser (another thing i cannot understand), i am left but no other choice than to use Programming Power to make multi-columns work. Now, I use three divs that float to left, and which are manually filled with text. Please don't laugh i know its stupid! But I would wish to not to have to worry about the columns and just have a one piece of (un-interrupted) text which all goes into only 1 div, and then have a program smart enough to split it up into X equally wide columns. Question: before i start reinvent the wheel, what methods of programming power have you known that tackle this elegantly? Please suggest your best working multi-column layout sources so I can evaluate which option is the best (I will update the below table). Exploring all possibilities 2011 and further, to enable multi column text user experience: Language Author SourceCodeUsage WorksOnAllMajorBrowser? ================================================================================= html manual labour put text manually in separate left-floating divs "Y" // Upside: control!

• Effective books for learning the intricacies of business application development?

  - by OffApps Cory

  I am a self taught "developer". I use the term loosely because I only know enough to make myself dangerous. I have no theory background, and I only pick up things to get this little tool to work or make that control do what I want. That said, I am looking for some reading material that explains some of the theory behind application development especially from a business standpoint. Really I need to understand what all of these terms that float around really talk about. Business Logic Layer, UI abstraction level and all that. Anyone got a reading list that they feel helped them understand this stuff? I know how to code stuff up so that it works. It is not pretty mostly because I don't know the elegant way of doing it, and it is not planned out very well (I also don't know how to plan an application). Any help would be appreciated. I have read a number of books on what I thought was the subject, but they all seem to rehash basic coding and what-not. This doesn't have to be specific to VB.NET or WPF (or Entity Framework) but anything with those items would be quite helpful.
