  • Web service request ignores basic WSDL XML element restrictions

    - by Oliver
    Hi all, I have encountered some difficulties while trying to validate an incoming soap message to a service I have running on JBoss AS (v. 5.1.0). In my code, I have explicitly set some fields to be required, eg: public class MyClass { @XmlElement(required=true, nillable=false) private List<myOtherObjects> myList; } This requirement is also reflected in the WSDL (note the lack of minOccurs="0"): <xs:element maxOccurs="unbounded" name="myList" type="tns:myOtherObjects" /> However, when I do a test soap message that has myList set to empty or null, these restrictions are completely ignored, forcing me to validate manually within the application logic on the service. I did some searching on the Internet and found out that, on WebLogic, the validation does not seem to be enabled by default, though it can be turned on by modifying the weblogic-webservices.xml file. (http://forums.oracle.com/forums/thread.jspa?threadID=783972&tstart=115) I’m wondering if there is something similar that I have to do with JBoss AS to enable automatic validation before the soap message reaches the service. Any help would be greatly appreciated. Oliver

  • Android Custom View Constructor

    - by Mitch
    I'm learning about using Custom Views from the following: http://developer.android.com/guide/topics/ui/custom-components.html#modifying The description says: Class Initialization As always, the super is called first. Furthermore, this is not a default constructor, but a parameterized one. The EditText is created with these parameters when it is inflated from an XML layout file, thus, our constructor needs to both take them and pass them to the superclass constructor as well. Is there a better description? I've been trying to figure out what the constructor(s) should look like and I've come up with 4 possible choices (see example at end of post). I'm not sure what these 4 choices do (or don't do), why I should implement them, or what the parameters mean. Is there a description of these? Thanks. Mitch public MyCustomView() { super(); } public MyCustomView(Context context) { super(context); } public MyCustomView(Context context, AttributeSet attrs) { super(context, attrs); } public MyCustomView(Context context, AttributeSet attrs, Map params) { super(context, attrs, params); }

  • How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

    - by Travesty3
    I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

  • Using for or while loops

    - by Gary
    Every month, 4 or 5 text files are created. The data in the files is pulled into MS Access and used in a mailmerge. Each file contains a header. This is an example: HEADER|0000000130|0000527350|0000171250|0000058000|0000756600|0000814753|0000819455|100106 The 2nd field is the number of records contained in the file (excluding the header line). The last field is the date in the form yymmdd. Using gawk (for Windows), I've done ok with rearranging/modifying the data and writing it all out to a new file for importing into Access except for the following. I'm trying to create a unique ID number for each record. The ID number has the form 1mmddyyXXXX, where XXXX is a number, padded with leading zeros. Using the header above, the first record in the output file would get the ID number 10106100001 and the last record would get the ID 10106100130. I've tried putting the second field in the header into a variable, rearranging the last header field into the required date format and then looping with "for" statements to append the XXXX part of the ID and then outputting it all with printf but so far I've been complete rubbish at it. Thanks for your help! gary

  • Custom Membership in ASP.NET MVC 2

    - by Interfector
    Hello, I'm trying to make my Custom Membership starting from ASP.NET's. I have a users table created by me which has as Primary Key a Guid UserId, exactly the sames as ASP.NET's default user and membership table. I have all the Foreign Key relationships built. However, I cannot insert the user into my custom users table. The data gets inserted correctly into the default ASP.NET's tables. I have tried the following scenarios: First version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) without modifying the user object, I try to insert it using EF's AddObject I receive the following error: "Cannot insert the value NULL into column 'LoweredUserName', table 'asp.dbo.aspnet_Users'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."} System.Exception {System.Data.SqlClient.SqlException The error actually makes sense as EF's AddObject doesn't know how to create the LoweredUserName value, and I don't want to do it, this is ASP.NET's job. Second version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) Get the Guid of the freshly inserted system user get the ASP.NET's User object and overwrite that of user.User get the ASP.NET's Membership object and overwrite that of user.Membership (remember the FKs) try again EF's AddObject new error {"The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects."} System.Exception {System.InvalidOperationException} Don't know what this is, but it certenly doesn't make any sense for me. After some googleing I think that it has something to do with the context, but as I'm a beginner I don't know how to fix it. Any ideeas on how to accomplish this task are more than welcomed, especially if they follow some good practices. Thx

  • Detection of page refresh / F5 key in ASP.NET MVC 2

    - by Michael
    How would one go about detecting a page refresh / F5 key push on the controller handling the postback? I need to distinguish between the user pressing one of two buttons (e.g., Next, Previous) and when the F5 / page refresh occurs. My scenario is a single wizard page that has different content shown between each invocation of the user pressing the "Next" or "Previous" buttons. The error that I am running into is when the user refreshes the page / presses the F5 key, the browser re-sends the request back to the controller, which is handled as a post-back and the FormCollection type is used to look for the "submitButton" key and obtain its value (e.g., "Next," "Send"). This part was modeled after the post by Dylan Beattie at http://stackoverflow.com/questions/442704/how-do-you-handle-multiple-submit-buttons-in-asp-net-mvc-framework. Maybe I'm trying to bend MVC 2 to where it isn't meant to go but I'd like to stay with the current design in that the underlying database drives the content and order of what is shown. This allows us to add new content into the database without modifying the code the displays the content. Thanks, Michael

  • How to make a GRANT persist for a table that's being dropped and re-created?

    - by Eli Courtwright
    I'm on a fairly new project where we're still modifying the design of our Oracle 11g database tables. As such, we drop and re-create our tables fairly often to make sure that our table creation scripts work as expected whenever we make a change. Our database consists of 2 schemas. One schema has some tables with INSERT triggers which cause the data to sometimes be copied into tables in our second schema. This requires us to log into the database with an admin account such as sysdba and GRANT access to the first schema to the necessary tables on the second schema, e.g. GRANT ALL ON schema_two.SomeTable TO schema_one; Our problem is that every time we make a change to our database design and want to drop and re-create our database tables, the access we GRANT-ed to schema_one went away when the table was dropped. Thus, this creates another annoying step wherein we must log in with an admin account to re-GRANT the access every time one of these tables is dropped and re-created. This isn't a huge deal, but I'd love to eliminate as many steps as possible from our development and testing procedures. Is there any way to GRANT access to a table in such a way that the GRANT-ed permissions survive a table being dropped and then re-created? And if this isn't possible, then is there a better way to go about this?

  • ASP.NET MVC Image refreshing

    - by user295541
    Hi, I have an Employee object which has an image property. Image class contains image metadata as image caption, and image file name. If I upload a new image for an employee on async way without full post back the new image is not appeared on the page. I use GUID to name the image file to avoid the page caching. I do the image modifying the following way: ctrEmployee employee = Repository.Get(PassedItemID); if (employee.ctrImage != null) { string fullFileName = serverFolder + employee.ctrImage.FileName; FileInfo TheFile = new FileInfo(fullFileName); if (TheFile.Exists) { TheFile.Delete(); } fileName = Guid.NewGuid() + ".jpg"; employee.ctrImage.FileName = fileName; } resizedBmp.Save(string.Format("{0}{1}", serverFolder, fileName), System.Drawing.Imaging.ImageFormat.Jpeg); Repository.Edit<ctrEmployee>(employee); ImageID = employee.Image.Value; return PartialView(UserControlPaths.Thumbnail, new ThumbnailDataModel(employee.Image.Value, 150, 150)); The partial view has an image tag which gets the saved image url string which is a GUID. Anybody has an idea what I do wrong?

  • Android ignores scrollbarsize

    - by Maragues
    Hi, I'm trying to modify a ListView scrollbar's width without success <ListView android:id="@+id/android:list" android:layout_width="fill_parent" android:layout_height="wrap_content" android:choiceMode="singleChoice" android:scrollbars="vertical" android:scrollbarTrackVertical="@drawable/scrollbar_vertical_track" android:scrollbarThumbVertical="@drawable/scrollbar_vertical_thumb" android:scrollbarSize="4px" android:clickable="true"/> First I tried using a drawable image 4px wide, but the .png was resized. Then I tried using a shape extracted from SamplesApi, without success. <shape xmlns:android="http://schemas.android.com/apk/res/android" android:width="40px"> <gradient android:startColor="#505050" android:endColor="#C0C0C0" android:angle="0"/> <corners android:radius="0dp" /> I've tried with and without the android:width attribute. There's a question on the same topic (http://stackoverflow.com/questions/2565083/width-of-a-scroll-bar-in-android), but it doesn't try anything different that what I'm already trying. As far as I know, creating my own theme shouldn't change the output. There's an example in SamplesApi (Views/ScrollBars). I tried modifying the scrollbarSize attribute without result. I know about ninepatch images, but there's an attribute which should do what I want. Any hint? Thanks in advance.

  • How do you word wrap a RichTextField for Blackberry

    - by Kai
    I've been trying to modify a rich text field to display correctly in its half of the horizontal field. The goal is this: --------------------------- | address is | ***********| | very long | ** IMAGE **| | state, zip | ***********| --------------------------- Where address is a single string separate from the city and zip. I am modifying the address field like this: RichTextField addrField = new RichTextField(address) { public int getPreferredWidth() { return 200; } protected void layout(int maxWidth,int maxHeight) { super.layout(getPreferredWidth(),maxHeight); setExtent(getPreferredWidth(), getHeight()); } }; The results look like this: ----------------------------- | address is ve| ***********| | state, zip | ** IMAGE **| | | ***********| ----------------------------- where clearly the address is just going under the image. Both horizontal fields are static 200 pixels wide. It's not like the system wouldn't know where to wrap the address. However, I have heard it is not easy to do this and is not done automatically. I have had no success finding a direct answer online. I have found people saying you need to do it in a custom layout manager, some refer to the RichTextField API, which is of no use. But nobody actually mentions how to do it. I understand that I may need to read character by character and set where the line breaks should happen. What I don't know is how exactly to do any of this. You can't just count characters and assume each is worth 5 pixels, and you shouldn't have to. Surely there must be some way to achieve this in a way that makes sense. Any suggestions?

  • How can I write classes that don't rely on "global" variables?

    - by Joel
    When I took my first programming course in university, we were taught that global variables were evil & should be avoided at all cost (since you can quickly develop confusing and unmaintainable code). The following year, we were taught object oriented programming, and how to create modular code using classes. I find that whenever I work with OOP, I use my classes' private variables as global variables, i.e., they can be (and are) read and modified by any function within the class. This isn't really sitting right with me, as it seems to introduce the same problems global variables had in languages like C. So I guess my question is, how do I stop writing classes with "global" variables? Would it make more sense to pretend I'm writing in a functional language? By this I mean having all functions take parameters & return values instead of directly modifying class variables. If I need to set any fields, I can just take the output of the function and assign it instead of having the function do it directly. This seems like it might make more maintainable code, at least for larger classes. What's common practice? Thanks!

  • Running multiple instances of tomcat in eclipse WTP

    - by lisak
    Hey, SCENARIO: 10 CATALINA_BASEs with own configuration (always the same port numbers 8080, but 10 different IP/hostnames on one host via virtual IPs). created a server in WTP and pick "Use the custom location" option in the server configuration in eclipse. New configuration files are created in workspace/Server/server-name-config/ Set up the server path and deploy path for my catalina base (not the internal .metadata one) After I started it, the new configuration files overwrote the original catalina-base/conf files I had there - I was glad, it should be like this but after I made changes in the eclipse config files workspace/Server/server-name-config/ and restarted the server, the changes didn't appeared in the original files in CATALINA_BASE/conf What the hell is that ? So I set the CATALINA_BASE/conf/server.xml to fault configuration and restarted tomcat from eclipse and it worked ! it took the configuration from /Server/server-name-config/server.xml Then I deleted CATALINA_BASE/conf/server.xml and it said that there is no server.xml in catalina base ! How is it possible ? I don't understand why eclipse WTP developers made so tight integration. There should by just symbolic links in /Server/server-name-config/ pointing to CATALINA_BASE/conf/ ... now there is a weird system which is totally unpredictable. The changes in /Server/server-name-config/ are not reflected in CATALINA_BASE/conf ... from where the standard bootstrap.jar or other catalina classloaders and classes build server, engine and other objects with particular setting. Moreover the CATALINA_BASEs could be used outside eclipse then. The second problem, I'm setting up various things in CATALINA_BASE/bin/startup.sh and setenv.sh which is easy cause I can use bash for it. Is then modifying VM parameters in the "Open launch configuration" settings the only way how to do it in eclipse ? Sorry for such a huge pile of questions, but I'm annoyed by the fact that it is much better to not use eclipse WTP for this because it is very poorly designed and it's a shame because this would spare me a lot of time. And using the internal .metadata/ instances it's even more terrifying way that the one I described.

  • How to debug anomalous C memory/stack problems

    - by EBM
    Hello, Sorry I can't be specific with code, but the problems I am seeing are anomalous. Character string values seem to be getting changed depending on other, unrelated code. For example, the value of the argument that is passed around below will change merely depending on if I comment out one or two of the fprintf() calls! By the last fprintf() the value is typically completely empty (and no, I have checked to make sure I am not modifying the argument directly... all I have to do is comment out a fprintf() or add another fprintf() and the value of the string will change at certain points!): static process_args(char *arg) { /* debug */ fprintf(stderr, "Function arg is %s\n", arg); ...do a bunch of stuff including call another function that uses alloc()... /* debug */ fprintf(stderr, "Function arg is now %s\n", arg); } int main(int argc, char *argv[]) { char *my_arg; ... do a bunch of stuff ... /* just to show you it's nothing to do with the argv array */ my_string = strdup(argv[1]); /* debug */ fprintf(stderr, "Argument 1 is %s\n", my_string); process_args(my_string); } There's more code all around, so I can't ask for someone to debug my program -- what I want to know is HOW can I debug why character strings like this are getting their memory changed or overwritten based on unrelated code. Is my memory limited? My stack too small? How do I tell? What else can I do to track down the issue? My program isn't huge, it's like a thousand lines of code give or take and a couple dynamically linked external libs, but nothing out of the ordinary. HELP! TIA!

  • PHP Regex to remove nested form elements but not input elements

    - by that0n3guy
    I'm modifying a PHP script that I have and it is currently outputting a nested form. Something like: <form name="input" action="html_form_action.asp" method="get"> <p>stuff here here, this may or may not be in a div, script, etc..</p> <form name="input" action="html_form_action.asp" method="get"> <div>stuff here possibilly</div> Username: <input type="text" name="user" /> <input type="submit" value="Submit" /> </form> <p>otherstuff this may or may not be in a div, script, etc..</p> </form> Nested form's are a no-no (IE hates them and basically causes the form to stop working), so I need to remove the nested form lines, but not the form items. I need to remove the nested: <form name="input" action="html_form_action.asp" method="get"> and </form> but not the outer <form and </form> or the input or submit stuff. Is this possible to do with regex? Note, the reason I just want to regex out the form rather than find the problem is because I know it will take some significant re-working to get rid of the double form... the regex solution is quick for now.

  • Dynamic Connection Strings for Strongly Typed DataSet in a Class Library using App.Config

    - by Luc
    This is my first question on StackOverflow.com and I'm not sure if this is the correct way to do this. I found a similar question titled: Modifying the Data Source for the Strongly Typed Dataset Connection String. However, the answer provided is not working for me. I'm not able to comment on it because I don't have enough "reputation points" (again, I just signed up), and I didn't want to provide an "answer", because I don't know the correct answer. My problem is that I need to be able to modify the connection string inside the generated myproject.dll.config file, but doing so has no effect for me at all. My library still uses the default connection string that was setup at design time. I've tried everything I know to try, but still no luck. I've tried working around the issue using multiple different approaches, but still the problem persists. I can't find any help on the internet with my specific problem either. It would be great if somebody could shed some light as to why my modified config file isn't being read. Useful information: I'm using a Strongly Typed DataSet I don't know the actual connection string at design time. The app.config doesn't allow me to specify a 'User' scoped connection string. I'm tied to a class library (no Windows Forms) Thank you for any help! Luc

  • Safe to update separate regions of a BufferedImage in separate threads?

    - by finnw
    I have a collection of BufferedImage instances, one main image and some subimages created by calling getSubImage on the main image. The subimages do not overlap. I am also making modifications to the subimage and I want to split this into multiple threads, one per subimage. From my understanding of how BufferedImage, Raster and DataBuffer work, this should be safe because: Each instance of BufferedImage (and its respective WritableRaster) is accessed from only one thread. The shared ColorModel is immutable The DataBuffer has no fields that can be modified (the only thing that can change is elements of the backing array.) Modifying disjoint segments of an array in separate threads is safe. However I cannot find anything in the documentation that says that it is definitely safe to do this. Can I assume it is safe? I know that it is possible to work on copies of the child Rasters but I would prefer to avoid this because of memory constraints. Otherwise, is it possible to make the operation thread-safe without copying regions of the parent image?

  • CIE XYZ colorspace: is it RGBA or XYZA?

    - by Tronic
    I plan to write a painting program based on linear combinations of xy plane points (0,1), (1,0 ) and (0,0). Such system works identically to RGB, except that the primaries are not within the gamut but at the corners of a triangle that encloses the entire gamut, therefore allowing for all colors to be reproduced. I have seen the three points being referred to as X, Y and Z (upper case) somewhere, but I cannot find the page anymore. My pixel format stores the intensity of each of those three components the same way as RGB does, together with alpha value. This allows using pretty much any image manipulation operation designed for RGBA without modifying the code. What is my format called? Is it XYZA, RGBA or something else? Google doesn't seem to know of XYZA and RGBA will get confused with sRGB + alpha (which I also need to use in the same program). Notice that the primaries X, Y and Z and their intensities have little to do with the x, y and z coordinates (lower case) that are more commonly used.

  • NSString's stringByAppendingPathComponent: removes a '/' in http://

    - by Jasarien
    I've been modifying some code to work between Mac OS X and iPhone OS. I came across some code that was using NSURL's URLByAppendingPathComponent: (added in 10.6), which as some may know, isn't available in the iPhone SDK. My solution to make this code work between OS's is to use NSString *urlString = [myURL absoluteString]; urlString = [urlString stringByAppendingPathComponent:@"helloworld"]; myURL = [NSURL urlWithString:urlString]; The problem with this is that NSString's stringByAppendingPathComponent: seems to remove one of the /'s from the http:// part of the URL. Is this intended behaviour or a bug? Edit Ok, So I was a bit too quick in asking the question above. I re-read the documentation and it does say: Note that this method only works with file paths (not, for example, string representations of URLs) However, it doesn't give any pointers in the right direction for what to do if you need to append a path component to a URL on the iPhone... I could always just do it manually, adding a /if necessary and the extra string, but I was looking to keep it as close to the original Mac OS X code as possible...

  • How to Create Element in XSLT When Copying Using Templates

    - by John Dumont
    Hello, I'm trying to create an element in an XML where the basic content is copied and modified. My XML is something like <root> <node> <child>value</child> <child2>value2</child2> </node> <node2>bla</node2> </root> The number of children of node may change as well as the children of root. The XSLT should copy the whole content, modify some values and add some new. The copying and modifying is no problem: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:output method="xml" encoding="UTF-8"/> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> (+ further templates for modifications). But how do I add a new element in this structure on some path, e.g. I want to add an element as the last element of the "node" node. The "node" element itself always exists.

  • Best approach to storing image pixels in bottom-up order in Java

    - by finnw
    I have an array of bytes representing an image in Windows BMP format and I would like my library to present it to the Java application as a BufferedImage, without copying the pixel data. The main problem is that all implementations of Raster in the JDK store image pixels in top-down, left-to-right order whereas BMP pixel data is stored bottom-up, left-to-right. If this is not compensated for, the resulting image will be flipped vertically. The most obvious "solution" is to set the SampleModel's scanlineStride property to a negative value and change the band offsets (or the DataBuffer's array offset) to point to the top-left pixel, i.e. the first pixel of the last line in the array. Unfortunately this does not work because all of the SampleModel constructors throw an exception if given a negative scanlineStride argument. I am currently working around it by forcing the scanlineStride field to a negative value using reflection, but I would like to do it in a cleaner and more portable way if possible. e.g. is there another way to fool the Raster or SampleModel into arranging the pixels in bottom-up order but without breaking encapsulation? Or is there a library somewhere that will wrap the Raster and SampleModel, presenting the pixel rows in reverse order? I would prefer to avoid the following approaches: Copying the whole image (for performance reasons. The code must process hundreds of large (= 1Mpixels) images per second and although the whole image must be available to the application, it will normally access only a tiny (but hard-to-predict) portion of the image.) Modifying the DataBuffer to perform coordinate transformation (this actually works but is another "dirty" solution because the buffer should not need to know about the scanline/pixel layout.) Re-implementing the Raster and/or SampleModel interfaces from scratch (but I have a hunch that I will be unable to avoid this.)

  • php: showing my country based on my IP, mysql optimized

    I'm downloaded WIPmania's worldip table from http://www.wipmania.com/en/base/ -- the table has 3 fields and around 79k rows: startip // example: 3363110912 endip // example: 3363112063 country // example: AR (Argentina) So, lets suppose i'm in Argentina and my IP address is: 200.117.248.17 1) I use this function to convert my ip to long function ip_address_to_number($ip) { if(!$ip) { return false; } else { $ip = split('\.',$ip); return($ip[0]*16777216 + $ip[1]*65536 + $ip[2]*256 + $ip[3]); } } 2) I search for the proper country code by matching the long converted ip: $sql = 'SELECT * FROM worldip WHERE '.ip_address_to_number($_SERVER['REMOTE_ADDR']).'

What if another bunch of argentinian guys also open the website and they all have these ip addresses: 200.117.248.17 200.117.233.10 200.117.241.88 200.117.159.24 Since i'm caching all the sql queries; instead of matching EACH of the ip queries in the database, would it be better (and right) just to match the 2 first sections of the ip by modifying the function like this? function ip_address_to_number($ip) { if(!$ip) { return false; } else { $ip = split('\.',$ip); return($ip[0]*16777216 + $ip[1]*65536); } } (notice that the 3rd and 4th splitted values of the IP have been removed). That way instead of querying these 4 values: 3363174417 3363170570 3363172696 3363151640 ...all i have to query is: 3363110912 (which is 200.117.0.0 converted to long). Is this right? any other ideas to optimize this process? Thanks!

  • How to refactor this database to allow sync. with smart clients?

    - by Anton Zvgny
    Howdy, I have inherited the following database: http://i46.tinypic.com/einvjr.png (EDIT: I cannot post images, so here goes the link) This currently runs 100% online thru an Asp.Net web app , but some employees will need to have offline access to this database to either get documents or to insert new documents for later synchronization when back to the office. What changes need to be made to this database scheme to support such scenario (sync smart clients with central web database)? Thanks! ps. I'm not an developer/dba, i'm just an mechanic engineer tasked with changing this app, so, take it easy on me :D ps1. We're using MSSQL Server for the online central database and MSSQL Compact for the smart client. ps2. the ImageGuid field of the images table is used to save the images to the file system. The web app takes the guid and create folders according to the first 3 initial letters to persist the image to the file system. ps3. The users of the smart client not always get server data first and then go modifying to sync later the changes. Most of the time they start working completely offline (with a blank local database) and later sync the data to the server. ps4. All the users of the smart client app have an account at the web app.

  • Django Template tag, generating template block tag

    - by Issy
    Hi Guys, Currently a bit stuck, wondering if anyone can assist. I am using django-adminfiles. Which is a near little application. I want to use it to insert images into posts/articles/pages for a site i am building. How django-adminfiles works is it inserts a placeholder i.e <<< ImageFile and this gets rendered using a django template. It also has the feature of inserting custom options i.e (Insert Medium Image) , i figured i would used this to automatically resize images and include it in the post (similar to how WP does it). Django-adminfiles makes use of sorl.thumbnail app to generate thumbnails. So i have tried testing generating thumbnails: The current template that is used to render the inserted image is: {% spaceless %} <img src="{{ upload.upload.url }}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I tried modifying this to: {% load thumbnail %} {% spaceless %} <img src="{% thumbnail upload.upload.url 200x50 %}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I get the error: Exception Value: Caught an exception while rendering: Source file: '/media/uploads/DSC_0014.jpg' does not exist. I figured the thumbnail needs the absolute path so tried putting that in the template, and that works. i.e this works: {% thumbnail '/Users/me/media/uploads/DSC_0014.jpg' 200x50 %} So basically i need to generate the absolute path to the file give the relative path (to web root). You could do this by passing the MEDIA_ROOT setting to the template, but the reason i want to do a template tag is to programmatically set the image size.

  • How to make designer generated .Net application settings portable

    - by Ville Koskinen
    Hello, I've been looking at modifying the source of the Doppler podcast aggregator with the goal of being able to run the program directly from my mp3 player. Doppler stores application settings using a Visual Studio designer generated Settings class, which by default serializes user settings to the user's home directory. I'd like to change this so that all settings would be stored in the same directory as the exe. It seems that this would be possible by creating a custom provider class which inherits the SettingsProvider class. Has anyone created such a provider and would like to share code? Update: I was able to get a custom settings provider nearly working by using this MSDN sample, i.e. with simple inheritance. I was initially confused as Windows Forms designer stopped working until I did this trick suggested at Codeproject: internal sealed partial class Settings { private MySettingsProvider settingsprovider = new MySettingsProvider(); public Settings() { foreach (SettingsProperty property in this.Properties) { property.Provider = settingsprovider; } ... The program still starts with window size 0;0 though. Anyone with any insight to this? Why the need to assing the provider in runtime---instead of using attributes as suggested by MSDN? Why the changes in how the default settings are passed to the application with the default settings provider vs. the custom one?
