  • NHibernate with nothing but stored procedures

    - by ChrisB2010
    I'd like to have NHibernate call a stored procedure when ISession.Get is called to fetch an entity by its key instead of using dynamic SQL. We have been using NHibernate and allowing it to generate our SQL for queries and inserts/updates/deletes, but now may have to deploy our application to an environment that requires us to use stored procedures for all database access. We can use sql-insert, sql-update, and sql-delete in our .hbm.xml mapping files for inserts/updates/deletes. Our hql and criteria queries will have to be replaced with stored procedure calls. However, I have not figured out how to force NHibernate to use a custom stored procedure to fetch an entity by its key. I still want to be able to call ISession.Get, as in: using (ISession session = MySessionFactory.OpenSession()) { return session.Get<Customer>(customerId); } and also lazy load objects, but I want NHibernate to call my "GetCustomerById" stored procedure instead of generating the dynamic SQL. Can this be done? Perhaps NHibernate is no longer a fit given this new environment we must support.

  • Flex 3 - Scroll bar issue

    - by Emma
    Im currently learning Flex, and Im having the hardest time getting scroll bars to work. In short Im pretty much just making a giant form for users to fill out, contained within a viewstack component, the user will type up information in one view, and it will be displayed in the other. But right now in the first canvas i have components that run of the screen and flex doesnt seem to automate a scroll bar, so i added in 'verticalScrollPolicy="on"' to my canvas, now while it gives me a scroll bar, it gives me an empty scroll bar, I still cannot move it up or down, meaning components are still trapped off the bottom of my screen. Im I missing something amazingly simple? Edit - Sorry, Im using Adobe Flex Builder 3, and the components it lets you drag in. http://img12.imageshack.us/img12/218/problem1f.jpg This is a picture of the problem, and i guess relavent code would be. <mx:Application xmlns:mx="adobe.com/2006/mxml"; layout="absolute" width="830" height="835"> <mx:ViewStack x="10" y="72" id="viewstack1" width="790" height="751" > <mx:Canvas label="Design Mode" width="100%" height="100%" verticalScrollPolicy="on" horizontalScrollPolicy="on" > (Components inside) </mx:Canvas> Sorry if Im using this site wrong, still very new

  • TeamCity and pending Git merge branch commit keeps build with failed tests

    - by Vladimir
    We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

  • Is it possible to disable user sessions for guest in Joomla 1.5

    - by WebolizeR
    Hi; Is it possible to disable session handling in Joomla 1.5 for guests. I donot use user system in the frontend, i assumed that it's not needed to run queries like below: Site will use APC or Memcache as caching system under heavy load, so it's important for me tHanks for your comments # DELETE FROM jos_session WHERE ( time < '1274709357' ) # SELECT * FROM jos_session WHERE session_id = '70c247cde8dcc4dad1ce111991772475' # UPDATE jos_session SET time='1274710257',userid='0',usertype='',username='',gid='0',guest='1',client_id='0',data='__default|a:8:{s:15:\"session.counter\";i:5;s:19:\"session.timer.start\";i:1274709740;s:18:\"session.timer.last\";i:1274709749;s:17:\"session.timer.now\";i:1274709754;s:22:\"session.client.browser\";s:88:\"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3\";s:8:\"registry\";O:9:\"JRegistry\":3:{s:17:\"_defaultNameSpace\";s:7:\"session\";s:9:\"_registry\";a:1:{s:7:\"session\";a:1:{s:4:\"data\";O:8:\"stdClass\":0:{}}}s:7:\"_errors\";a:0:{}}s:4:\"user\";O:5:\"JUser\":19:{s:2:\"id\";i:0;s:4:\"name\";N;s:8:\"username\";N;s:5:\"email\";N;s:8:\"password\";N;s:14:\"password_clear\";s:0:\"\";s:8:\"usertype\";N;s:5:\"block\";N;s:9:\"sendEmail\";i:0;s:3:\"gid\";i:0;s:12:\"registerDate\";N;s:13:\"lastvisitDate\";N;s:10:\"activation\";N;s:6:\"params\";N;s:3:\"aid\";i:0;s:5:\"guest\";i:1;s:7:\"_params\";O:10:\"JParameter\":7:{s:4:\"_raw\";s:0:\"\";s:4:\"_xml\";N;s:9:\"_elements\";a:0:{}s:12:\"_elementPath\";a:1:{i:0;s:74:\"C:\xampp\htdocs\sites\iv.mynet.com\libraries\joomla\html\parameter\element\";}s:17:\"_defaultNameSpace\";s:8:\"_default\";s:9:\"_registry\";a:1:{s:8:\"_default\";a:1:{s:4:\"data\";O:8:\"stdClass\":0:{}}}s:7:\"_errors\";a:0:{}}s:9:\"_errorMsg\";N;s:7:\"_errors\";a:0:{}}s:13:\"session.token\";s:32:\"a2b19c7baf223ad5fd2d5503e18ed323\";}' WHERE session_id='70c247cde8dcc4dad1ce111991772475'

  • video streaming infrastructure

    - by alchemical
    We would like to set-up a live video-chat web site and are looking for basic architectural advice and/or a recomendation for a particular framework to use. Here are the basic features of the site: Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

  • Constant error in compiler using C#'s provided objects

    - by dotnetdev
    I have used the built in C# methods to write a compiler, like the following: CodeDomProvider codeProvider = CodeDomProvider.CreateProvider("CSharp"); string Output = "Out.exe"; Button ButtonObject = (Button)sender; this.RadTextBox1.Text = string.Empty; System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters(); //Make sure we generate an EXE, not a DLL parameters.GenerateExecutable = true; parameters.OutputAssembly = Output; CompilerResults results = codeProvider.CompileAssemblyFromSource(parameters, RadTextBox1.Text); if (results.Errors.Count > 0) { RadTextBox2.ForeColor = Color.Red; foreach (CompilerError CompErr in results.Errors) { RadTextBox2.Text = RadTextBox2.Text + "Line number " + CompErr.Line + ", Error Number: " + CompErr.ErrorNumber + ", '" + CompErr.ErrorText + ";" + Environment.NewLine + Environment.NewLine; } } else { //Successful Compile RadTextBox2.ForeColor = Color.Blue; Guid guid = Guid.NewGuid(); string PathToExe = Server.MapPath(Path.Combine(@"\Compiled" , Output)); FileStream fs = System.IO.File.Create(PathToExe); using (StreamWriter sw = new StreamWriter(fs)) { sw.Write(RadTextBox1.Text); } Response.WriteFile(PathToExe); When I run this code and write a Main method (such as the code sample in http://msdn.microsoft.com/en-us/library/ms228506(VS.80).aspx, I get this error: Line number 0, Error Number: CS5001, 'Program 'c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Out.exe' does not contain a static 'Main' method suitable for an entry point; The code above is used as the basis of a compiler on my site (not yet live). So you type in code and generate an .exe assembly. But when I enter code into the textbox for code writing (Radtextbox1), even with a main method, I get the error. What gives? Thanks

  • Bibliography behaves strange in lyx.

    - by Orjanp
    Hi! I have created a Bibliography section in my document written in lyx. It uses a book layout. For some reason it did start over again when I added some more entries.

  • Invalid iPhone Application Binary

    - by Kristopher Johnson
    I'm trying to upload an application to the iPhone App Store, but I get this error message from iTunes Connect: The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate. My guess is that it is not properly signed. I have downloaded my App Store distribution certficate, but I can't figure out how to "sign" my application with it. The SDK's documentation about code signing is not very helpful. (FWIW, I can install the app on my iPhone just fine using the development provisioning profile.) However, it is possible that I screwed things up on a more basic level. Here's what I did to try to prepare it for upload: In Xcode, select the Device|Release target Select the target and click the Info button. Change "Code Signing Identity" to "iPhone Distribution", and change "Code Signing Provisioning Profile" to my App Store distribution profile. Build Go to the directory where the built MyApp.app bundle is, control-click and choose "Compress" to create MyApp.zip Upload MyApp.zip to the App Store via iTunes Connect (which resulted in the above error message). Can anybody give me any hints? Edit: Found someone with the same problem. Unfortunately, he won't tell us how he fixed it. http://www.rhonabwy.com/wp/2008/07/18/seattlebus-diary-ongoing-update-saga/#comments http://www.rhonabwy.com/wp/2008/07/22/seattlebus-diary-update-is-pending-review/ (Note: For general information on submitting iPhone applications to the App Store, see Steps to upload an iPhone application to the AppStore.)

  • How do I debug a HTTP 502 error?

    - by Bialecki
    I have a Python Tornado server sitting behind a nginx frontend. Every now and then, but not every time, I get a 502 error. I look in the nginx access log and I see this: 127.0.0.1 - - [02/Jun/2010:18:04:02 -0400] "POST /a/question/updates HTTP/1.1" 502 173 "http://localhost/tagged/python" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3" and in the error log: 2010/06/02 18:04:02 [error] 14033#0: *1700 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: _, request: "POST /a/question/updates HTTP/1.1", upstream: "http://127.0.0.1:8888/a/question/updates", host: "localhost", referrer: "http://localhost/tagged/python" I don't think any errors show up in the Tornado log. How would you go about debugging this? Is there something I can put in the Tornado or nginx configuration to help debug this? EDIT: In addition, I get a fair number of 504, gateway timeout errors. Is it possible that the Tornado instance is just busy or something?

  • Deployed a Zend App on EC2 and its not working

    - by Gublooo
    Hey Guys, I'm confused about the problem and not sure if I can provide enough details. I have a php app built on Zend framework which I've successfully deployed on other hosting companies. I am now trying to move to Amazon EC2 I moved all my code and set my domain to point to the IP address. So far so good. Now when I access my home page say www.example.com - everything looks good - The home page opens up which means the IndexController is being called and the index method is properly executed which pulls data from the database and displays it in the index.phtml page. So this lets me to believe that everything is working fine. But every link I click on the home page whether its a simple contact us link - or any other action that I directly try to call even through the URL results in 404 Not Found The requested URL /user/add was not found on this server. Apache/2.2.9 (Fedora) Server at www.example.com Port 80 The interesting thing is the home page opens up fine when I call www.example.com but when I give the entire path which is www.example.com/index/index - I get the same above error. I have checked the logs and there are no errors. Has anyone encountered something similar or have any idea if I'm missing a simple step or something like rewrite rule maybe. Its running on LAMP Any ideas Thanks

  • Missing WM_PAINT when hosting a WPF control inside a winforms application.

    - by Boris
    Hi All, Consider the following scenario: 1) Create a winforms application with an empty form. 2) Create a WPF usercontrol in the same project which is just the default control with background changed to blue. <UserControl x:Class="WindowsFormsApplication2.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300" Background="Blue"> <Grid> </Grid> </UserControl> 3) Build the project 4) Add the control to your form (an ElementHost is added and the control is added inside it). 5) Run the application (everything looks nice) 6) Start Spy++, click find window (Control+F) and move the cursor onto the WPF control (the blue square) Something strange happens, the control gets a WM_ERASEBKGND message but no WM_PAINT message so now it is white. You can resize the form, hide the form behind other windows and the WPF control will not get rendered. There is an image of the scenario here: http://img260.imageshack.us/img260/2296/wmpaint.png This is a simplified example of the situation I have in the actual application. Please tell me what is the best way to resolve this issue such that the WPF control renders itself correctly. I would like a solution that can be incorporated into a large application with many controls on the form. Thank you very much in advance, Boris

  • Starting a new business with former colleagues, advice needed

    - by Sparafusile
    I was recently contacted by a former boss of mine who is thinking of starting a new business. The business will be online only it will by my job to design, build, and maintain the software going into it. I will also have to maintain the server it's running on, being the only technical person on the team. I will be one of four members of the business, the other three being the actual business know-hows and salesmen. The other three are shouldering the cost of getting the business going (incorporation, attorney fees, etc) and we will be splitting the cost of the server. I have no business knowledge at all, and don't want any part of it, I am only interested in the technical aspects. Now that we are finalizing our plans, determining roles, and getting ready to start actual work, we have come to the point where we have to determine what percentage stake each of us has. Since I have never done anything like this before, or met anyone that has, I don't know what I should expect. Can anyone give me some pointers on what to ask for in this deal?

  • Call to CFC via Ajax-POST does not work

    - by Philipp
    We have the following problem: A CFC-method that is called from AJAX suddenly redirects the request to cfcexplorer instead of executing the request. The strange thing is, that the problem only occurs when we make the ajax call via "POST" method, like this: // This will return the HTTP Status header: // Location: http://url.to:80/CFIDE/componentutils/cfcexplorer.cfc?method=getcfcinhtml&name=web.ajax&path=/web/ajax.cfc $.post( "http://url.to/ajax.cfc", {method: "test"}, function(res) { alert("ajax.cfc POST return:" + res); } ); Making the same request as "GET" request works perfectly: // This will call the method "test" of web/ajax.cfc $.get( "http://url.to/ajax.cfc", {method: "test"}, function(res) { alert("ajax.cfc GET return:" + res); } ); This is the ajax.cfc file (dummy file): <cfcomponent> <cffunction name="test" access="remote" returntype="Any" returnformat="JSON"> <cfset j = {}> <cfset j.data = "this is the data"> <cfreturn serializeJson(j)> </cffunction> </cfcomponent> What really puzzles us is that the request did work in the past (we have a lot of code all making ajax calls via POST and CF-code that expects FORM-data to be present, so we cannot simply change the method to GET) Maybe there was some setting that has changed or similar...

  • How to create an Universal Binary for iTunes Connect Distribution?

    - by balexandre
    I created an app that was rejected because Apple say that my App was not showing the correct iPad window and it was showing the same iPhone screen but top left aligned. Running on simulator, I get my App to show exactly what it should, a big iPad View. my app as Apple referees that is showing on device: my app running the simulator (50% zoom only): my code in the Application Delegate is the one I published before - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // The default have the line below, let us comment it //MainViewController *aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; // Our main controller MainViewController *aController = nil; // Is this OS 3.2.0+ ? #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) // It's an iPad, let's set the MainView to our MainView-iPad aController = [[MainViewController alloc] initWithNibName:@"MainView-iPad" bundle:nil]; else // This is a 3.2.0+ but not an iPad (for future, when iPhone/iPod Touch runs with same OS than iPad) aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; #else // It's an iPhone/iPod Touch (OS < 3.2.0) aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; #endif // Let's continue our default code self.mainViewController = aController; [aController release]; mainViewController.view.frame = [UIScreen mainScreen].applicationFrame; [window addSubview:[mainViewController view]]; [window makeKeyAndVisible]; return YES; } on my target info I have iPhone/iPad My question is, how should I build the app? Use Base SDK iPhone Simulator 3.1.3 iPhone Simulator 3.2 my Active Configuration is Distribution and Active Architecture is arm6 Can anyone that already published app into iTunes Connect explain me the settings? P.S. I followed the Developer Guideline on Building and Installing your Development Application that is found on Creating and Downloading Development Provisioning Profiles but does not say anything regarding this, as I did exactly and the app was rejected.

  • Using SoapExtensionAttributes on client side with async web methods

    - by Maxim Polishchuk
    Hey, I have a simple question. I implemented custom soap extension and registered it into client application configuration file. It works fine. (I would like to implement progress bar functionality like http://msdn.microsoft.com/en-us/library/aa480520.aspx) But I don't like some thing - custom soap extension is invoked by every call of my web service. In order to fix this situation (call WS just by required methods) I implemented custom SoapExtensionAttribute like below: [AttributeUsage(AttributeTargets.Method)] public class CustomSoapExtensionAttribute : SoapExtensionAttribute { public override int Priority { get; set; } public CustomSoapExtensionAttribute() : this (1) { } public CustomSoapExtensionAttribute(int priority) { Priority = priority; } public override Type ExtensionType { get { return typeof(CustomSoapExtension); } } } I added this attribute to required methods of web service proxy classes (and removed registration into client configuration file). My soap extension doesn't invoke when required web methods are calling. Can someone help me to solve this problem or select any other solution? Anotherone, I don't know it is important or not - my required methods are async web methods. Best regards, Maxim

  • Why not systematically attach event in WPF instead of using delegate ?

    - by user310291
    For a button to handle event, we can add a delegate to the click property of the button: this.button1.Click += new System.EventHandler(this.button1_Click); But in WPF contrary to Winform, you can also attach a handler http://msdn.microsoft.com/en-us/magazine/cc785480.aspx So why not do so for the button ? Is performance better in first case maybe ? Update: I mean this Attached Events In order to enable elements to handle events that are declared in a different element, WPF supports something called attached events. Attached events are routed events that support a hookup in XAML on elements other than the type on which the event is declared. For example, if you want the Grid element to listen for a Button.Click event to bubble past, you would simply hook it up like the following: <Grid Button.Click="myButton_Click"> <Button Name="myButton" >Click Me</Button> </Grid> The resulting code in the compile-time-generated partial class now looks like this: #line 5 "..\..\Window1.xaml" ((System.Windows.Controls.Grid)(target)).AddHandler( System.Windows.Controls.Primitives.ButtonBase.ClickEvent, new System.Windows.RoutedEventHandler(this.myButton_Click));

  • OpenCV to JNI how to make it work?

    - by user293252
    I am tring to use opencv and java for face detection, and in that pursit i found this "JNI2OPENCV" file....but i am confused on how to make it work, can anyone help me? http://img519.imageshack.us/img519/4803/askaj.jpg and the following is the FaceDetection.java class JNIOpenCV { static { System.loadLibrary("JNI2OpenCV"); } public native int[] detectFace(int minFaceWidth, int minFaceHeight, String cascade, String filename); } public class FaceDetection { private JNIOpenCV myJNIOpenCV; private FaceDetection myFaceDetection; public FaceDetection() { myJNIOpenCV = new JNIOpenCV(); String filename = "lena.jpg"; String cascade = "haarcascade_frontalface_alt.xml"; int[] detectedFaces = myJNIOpenCV.detectFace(40, 40, cascade, filename); int numFaces = detectedFaces.length / 4; System.out.println("numFaces = " + numFaces); for (int i = 0; i < numFaces; i++) { System.out.println("Face " + i + ": " + detectedFaces[4 * i + 0] + " " + detectedFaces[4 * i + 1] + " " + detectedFaces[4 * i + 2] + " " + detectedFaces[4 * i + 3]); } } public static void main(String args[]) { FaceDetection myFaceDetection = new FaceDetection(); } } CAn anyone tell me how can i make this work on Netbeans?? I tried Google but help on this particular topic is very meger. I have added the whole folder as Llibrary in netbeans project and whe i try to run the file i get the followig wrroes. Exception in thread "main" java.lang.UnsatisfiedLinkError: FaceDetection.JNIOpenCV.detectFace(IILjava/lang/String;Ljava/lang/String;)[I at FaceDetection.JNIOpenCV.detectFace(Native Method) at FaceDetection.FaceDetection.<init>(FaceDetection.java:19) at FaceDetection.FaceDetection.main(FaceDetection.java:29) Java Result: 1 BUILD SUCCESSFUL (total time: 2 seconds) CAn anyone tell me the exact way to work with this? like what all i have to do?

  • how to combine widget webapp framework with SEO-friendly CSS and JS files

    - by Ali
    Hi guys, I'm writing a webapp using Zend framework and a homebrew widget system. Every widget has a controller and can choose to render one of many views if it chooses. This really helps us modularize and reconfigure and reuse the widgets anywhere on the site. The Problem is that the views of each widget contain their own JS and CSS code, which leads to very messy HTML code when the whole page is put together. You get pockets of style and script tags everywhere. This is bad for a lot of different reasons as I'm sure you know, but it has a profound effect on our SEO as well. Several solutions that I've been able to come up with: Separate the CSS and JS of every view of every widget into its own file - this has serious drawbacks for load times (many more resources have to be loaded separately) and it makes coding very difficult as now you have to have 3-4 files open just to edit a widget. combine the all the widget CSS into a single file (same with JS) - would also lead to a massive load when someone enters the site, mixes up the CSS and the JS for all widgets so it's harder to keep track of them, and other problems that I'm sure you can think of. Create a system that uses method 1 (separate CSS and JS for every widget), when delivering the page, stitches all CSS and JS together. This obviously needs more processing time and of course the creation of such a system, etc. My Question is what you guys think of these solutions or if there are pre-existing solutions that you know of (or any tech that might help) solve this problem. I really appreciate all of your thoughts and comments!! Thanks guys, Ali

  • Convert function to read from string instead of file in C

    - by Dusty
    I've been tasked with updating a function which currently reads in a configuration file from disk and populates a structure: static int LoadFromFile(FILE *Stream, ConfigStructure *cs) { int tempInt; ... if ( fscanf( Stream, "Version: %d\n",&tempInt) != 1 ) { printf("Unable to read version number\n"); return 0; } cs->Version = tempInt; ... } to one which allows us to bypass writing the configuration to disk and instead pass it directly in memory, roughly equivalent to this: static int LoadFromString(char *Stream, ConfigStructure *cs) A few things to note: The current LoadFromFile function is incredibly dense and complex, reading dozens of versions of the config file in a backward compatible manner, which makes duplication of the overall logic quite a pain. The functions that generate the config file and those that read it originate in totally different parts of the old system and therefore don't share any data structures so I can't pass those directly. I could potentially write a wrapper, but again, it would need to handle any structure passed in in a backwards compatible manner. I'm tempted to just pass the file as is in as a string (as in the prototype above) and convert all the fscanf's to sscanf's but then I have to handle incrementing the pointer along (and potentially dealing with buffer overrun errors) manually. This has to remain in C, so no C++ functionality like streams can help here Am I missing a better option? Is there some way to create a FILE * that actually just points to a location in memory instead of on disk? Any pointers, suggestions or other help is greatly appreciated.

  • Windows with Plesk Panel installs ActiveState Python 2.5.0 - any thoughts?

    - by B Mahoney
    I expect to run Pylons on a Windows Server 2003 and IIS 6 on a Virtual Private Server (VPS). Most work with the VPS is done through the Plesk 8.6 panel. The Plesk panel has a lot of maintenance advantages for us. However, this Plesk configuration installs ActiveState Python 2.5.0. The Parallels Plesk documents for 8.6 and version 9 insist that only this configuration should be installed. I'm not eager to settle for the baseline 2.5.0. but don't see any safe upgrade path. How has ActiveState Python 2.5.0 been for other users? Can you replace the Parallels\Plesk\Additional\Python with another distribution? I don't want to break Plesk, please. Previously, I followed these instructions, Serving a Pylons app with IIS - Pylons Cookbook Using the default web site IP address, I had Python 2.6.3 installing the ISAPI-WSGI dll in IIS so that I successfully ran Pylons in a virutalenv through IIS using the IP address, no domain name. I would be so happy if I could run this successful configuration for my domains while I must use Plesk. Tips and solutions appreciated.

  • How to transform coordinate from WGS84 to a coordinate in a projection in PROJ.4?

    - by Sanoj
    I have a GPS-coordinate in WGS84 that I would like to transform to a map-projection coordinate in SWEREF99 TM using PROJ.4 in Java or proj4js in JavaScript. Its hard to find documentation for PROJ.4 and how to us it. If you have a good link, please post it as a comment. The PROJ.4 parameters for SWEREF99 TM is +proj=utm +zone=33 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs I have tried to use a PROJ.4 Java library and tried this code and values: String[] proj4_w = new String[] { "+proj=utm", "+zone=33", "+ellps=GRS80", "+towgs84=0,0,0,0,0,0,0", "+units=m", "+no_defs" }; Projection proj = ProjectionFactory.fromPROJ4Specification(proj4_w); Point2D.Double testLatLng = new Point2D.Double(55.0000, 12.7500); Point2D.Double testProjec = proj.transform(testLatLng, new Point2D.Double()); This give me the point Point2D.Double[5197915.86288144, 1822635.9083898761] but I should be N: 6097106.672, E: 356083.438 What am I doing wrong? and what method and parameters should I use instead? The correct values is taken from Lantmäteriet. I am not sure if proj.transform(testLatLng, new Point2D.Double()); is the right method to use.

  • What vertex shader code should be used for a pixel shader used for simple 2D SpriteBatch drawing in XNA?

    - by Michael
    Preface First of all, why is a vertex shader required for a SilverlightEffect (.slfx file) in Silverlight 5? I'm trying to port a simple 2D XNA game to Silverlight 5 RC, and I would like to use a basic pixel shader. This shader works great in XNA for Windows and Xbox, but I can't get it to compile with Silverlight as a SilverlightEffect. The MS blog for the Silverlight Toolkit says that "there is no difference between .slfx and .fx", but apparently this isn't quite true -- or at least SpriteBatch is working some magic for us in "regular XNA", and it isn't in "Silverlight XNA". If I try to directly copy my pixel shader file into a Silverlight project (and change it to the supported "Effect - Silverlight" importer/processor), when I try to compile I see the following error message: Invalid effect file. Unable to find vertex shader in pass "P0" Indeed, there isn't a vertex shader in my pixel shader file. I haven't needed one with my other 2D XNA apps since I'm just doing basic SpriteBatch drawing. I tried adding a vertex shader to my shader file, using Remi Gillig's comment on this Shawn Hargreaves blog post for guidance, but it doesn't quite work. The shader file successfully compiles, and I see some semblance of my game on screen, but it's tiny, twisted, repeated, and all jumbled up. So clearly something's not quite right. The Real Question So that brings me to my real question: Since a vertex shader is required, is there a basic vertex shader function that works for simple 2D SpriteBatch drawing? And if the vertex shader requires world/view/project matricies as parameters, what values am I supposed to use for a 2D game? Can any shader pros help? Thanks!

  • Seperation of game- and rendering logic

    - by Qua
    What is the best way to seperate rendering code from the actually game engine/logic code? And is it even a good idea to seperate those? Let's assume we have a game object called Knight. The Knight has to be rendered on the screen for the user to see. We're now left with two choices. Either we give the Knight a Render/Draw method that we can call, or we create a renderer class that takes care of rendering all knights. In the scenario where the two is seperated the Knight should the knight still contain all the information needed to render him, or should this be seperated as well? In the last project we created we decided to let all the information required to render an object be stored inside the object itself, but we had a seperate component to actually read those informations and render the objects. The object would contain information such as size, rotation, scale, and which animation was currently playing and based on this the renderer object would compose the screen. Frameworks such as XNA seem to think joining the object and rendering is a good idea, but we're afraid to get tied up to a specific rendering framework, whereas building a seperate rendering component gives us more freedom to change framework at any given time.
