• Image surrounded by text in WPF

  - by niao

  Greetings, I have some control which display bunch of textblocks and image. I would like the image to be surrounded by text. I have already implemented some functionality by using FlowDocument and custom bindable run control. (These controls are included inside user control). When I generate lots of these controls in treeview, application goes into infinite loop. I asked on forums before about this problem and the answer was that it can be WPF issue. Howver when I removed bindable run from my user control, problem dissappeared. Now I am trying to implement other solution where image will be surrounded by text. Can someone please help me? EDIT: Generally i would like to achieve something like this

• msvsmon is locking up my pdbs

  - by Sam Saffron

  During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

• How to preprocess a Django model field value before return?

  - by Satoru.Logic

  Hi, all. I have a Note model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) The conversed value is saved into the database, which is not what I wanna see. Would you please tell me what's wrong with this? Thanks in advance.

• Criteria for selecting software for embedded device

  - by Suresh Kumar

  We are currently evaluating Web servers for an embedded device. We have laid down the evaluation criteria for things like HTTP version, Security, Compression etc. On the embeddable side, we have identified the following criteria: Memory footprint Memory management (support for plugging in a custom memory manager) CPU usage Thread usage (support for thread pool) Portability What I want inputs on is: Are there any other criteria that an embeddable software should meet? What exactly does it mean when someone says that a software is designed for embeddable use? We currently have zeroed in on two Web servers: AppWeb Lighttpd (lighty) Feature wise, both the above Web servers seem to be on par. However, it is claimed that AppWeb is designed for embedded use while Lighttpd is not. To choose between the above two Web servers, what criteria should I be looking at?

• How can I define pre/post-increment behavior in Perl objects?

  - by Zaid

  Date::Simple objects display this behavior. In the case of Date::Simple objects, $date++ returns the next day's date. Date::Simple objects are immutable. After assigning $date1 to $date2, no change to $date1 can affect $date2. This means, for example, that there is nothing like a set_year operation, and $date++ assigns a new object to $date. How can one custom define the pre/post-incremental behavior of an object, such that ++$object or $object-- performs a particular action? I've skimmed over perlboot, perltoot, perltooc and perlbot, but I don't see any examples showing how this can be done.

• Drupal: Multiple Stylesheets

  - by Vecta

  I'm currently creating a custom Drupal theme for my company and I'm having trouble getting multiple stylesheets to load. I followed the instructions on this page by adding stylesheets to the .info file in the format: stylesheets[all][] = style.css stylesheets[all][] = name2.css etc... However, when I load the page nothing changes and when I view source, it consistently lists style.css but seems to ignore the others. Am I misunderstood in the process of adding additional stylesheets? What could I be doing incorrectly? Thanks for any help!

• Undefined Variable in Matlab

  - by OrangeRind

  The Following is the basic skeleton for my MATLAB program. Each box is a class definition. Scroll down for the error. Note: Each Class has a custom constructor which does not require an external parameter The Error Undefined function or variable 'Troom'. Error in == wallwall.wall at 31 function o = wall(Tr) Error in == mainfile at 5 w1 = wall(); This comes when I create an object of Class wall from another file "mainfile" Question Why is this happening? Am I getting wrong in the concepts of OOP for Matlab specific? How do I resolve this? Thanks in Advance!

• ListView in ArrayAdapter order get's mixed up when scrolling

  - by Dan B

  Hi, I have a ListView in a custom ArrayAdapter that displays an icon ImageView and a TextView in each row. When I make the list long enough to let you scroll through it, the order starts out right, but when I start to scroll down, some of the earlier entries start re-appearing. If I scroll back up, the old order changes. Doing this repeatedly eventually causes the entire list order to be seemingly random. So scrolling the list is either causing the child order to change, or the drawing is not refreshing correctly. What could cause something like this to happen? I need the order the items are displayed to the user to be the same order they are added to the ArrayList, or at LEAST to remain in one static order. If I need to provide more detailed information, please let me know. Any help is appreciated. Thanks.

• Is there a SortedList<T> class in .net ? (not SortedList<Key,Value> which is actually a kind of Sort

  - by Brann

  I need to sort some objects according to their contents (in fact according to one of their properties, which is NOT the key and may be duplicated between different objects) .net provides two classes (SortedDictionnary and SortedList), and both are some kind of Dictionaries. The only difference (AFAIK) is that SortedDictionnary uses a binary tree to maintain its state whereas SortedList does not and is accessible via an index. I could achieve what I want using a List, and then using its Sort() method with a custom implementation of IComparer, but it wouldn't be time-efficient as I would sort the whole List each time I insert a new object, whereas a good SortedList would just insert the item at the right position. What I need is a SortedList class with a RefreshPosition(int index) to move only the changed (or inserted) object rather than resorting the whole list each time an object inside changes. Am I missing something obvious ?

• Best way to play MIDI sounds using C#

  - by jerhinesmith

  I'm trying to rebuild an old metronome application that was originally written using MFC in C++ to be written in .NET using C#. One of the issues I'm running into is playing the midi files that are used to represent the metronome "clicks". I've found a few articles online about playing MIDI in .NET, but most of them seem to rely on custom libraries that someone has cobbled together and made available. I'm not averse to using these, but I'd rather understand for myself how this is being done, since it seems like it should be a mostly trivial exercise. So, am I missing something? Or is it just difficult to use MIDI inside of a .NET application?

• Dynamic data validation in ASP.NET MVC

  - by user252160

  I've recently read about the model validation capabilities of ASP.NET MVC which are all very cool until a certain point. What happens if the application doesn't know the data that it works with because it is all stored in DB and built together at runtime. Just like in Drupal, I'd like to be able to define custom types at runtime, and assign runtime validation rules as well. Obviously, the idea of assigning attributes to well established models is now gone. What else could be done ? I am thinking in terms of rules being stored as JSON objects in the DB fields or something like that.

How would I change these values?

• Does DataType DataAnnotation Check the Expression?

  - by Jason

  I am currently using DataAnnotations within my ASP.NET MVC website to ensure data is properly validated. One question I wanted to verify (I think I know the answer, but I can't find verification online) - does the DataType DataAnnotation perform regular expression checks to ensure that you have received a valid e-mail/phone/currency/etc? [Required(ErrorMessage = "Price required")] [DataType(DataType.Currency, ErrorMessage = "Not a valid price")] [Range(0, double.MaxValue, ErrorMessage = "Price must be greater than 0.")] public decimal Price { get; set; } I believe the answer is no (meaning I have to provide my own, custom, RegularExpressionAttribute), but I wanted to double check before I do that for various field types.

• user model password field default password field in django

  - by imran-glt

  Hi, I've created a custom user model in my application. This user model is working fine, but there are a couple of problems I have with it. 1) The change password link in the my register.html page doesn't work? 2) The default password box on the add/edit page for a user is a little unfriendly. Ideally, what I'd like is the two password fields from the change password form on the add/edit user form in the admin, which will automatically turn convert the entered password into a valid encrypted password in Django. This would make the admin system MUCH friendlier and much more suited to my needs, as a fair number of user accounts will be created and maintained manually in this app, and the person responsible for doing so will likely be scared off at the sight of that admin field, or just type a clear text password and wonder why it doesn't work. Is this possible / How do I do this?

• Using installshield to replace a same-versioned DLL in the GAC

  - by Kevin

  We recently put out an update of one of our apps with a "test" DLL from a third party. The third party does not update their assembly versions on the dll's, only the file versions, so multiple apps can reference different "versions" of it. However, the GAC still allows us to keep the newest version, because it also checks the file version which is always updated. What happened is we were not ready to release this DLL, but it got out there on some customer machines. I would like to put our current live version back out there, but it has an older file version (and the same assembly version) as the test DLL. We have multiple apps referencing this DLL, so I can't simply delete it and drop in the new one. Is there a way to replace the DLL in the GAC? I'm using installshield 2009. Perhaps some sort of custom action upon install?

• Is there a way to force HTTPS protocol in a Kohana 2.3 site?

  - by alex

  I've got a site built on top of Kohana 2.3 which I now have to make all links https. I set this in application/config/config.php. $config['site_protocol'] = 'https'; This makes all links on the site use the https protocol. Except, when I first enter the site via http, it will not automatically forward to https. Is there a way to make Kohana do this, or do I just need to do some custom coding? I've found this .htaccess rule too, will it be fine to just drop this in? RewriteEngine On RewriteCond %{SERVER_PORT} !=443 RewriteRule ^ https://yourdomain.tld%{REQUEST_URI} [NS,R,L] Thanks.

• How can the javascript plugin architecture in raphael/jquery be done?

  - by TimDog

  I'm looking for a barebones javascript example that demonstrates how the javascript plugin architecture works with large javascript libraries (such as raphael or jquery). In either scenario, you build plugins by ensuring your custom plugin follows this pattern: jQuery.fn.pluginName -- so assume I have a library: myLibrary = (function() { //my fancy javascript code return function() { //my return object }; }); How would fn be incorporated into the above myLibrary object to ensure that he resulting plugin is callable? I instantiate myLibrary like so: var lib = new myLibrary(); And now I have included a reference to my plugin in my page: myLibrary.fn.simplePlugin = function() { //more fancy code } So finally, I can just call: lib.simplePlugin(); Basically, what magic is actually occuring when the .fn is used during the creation of the plugin?

• embed multiple youtube videos to chromeless player cue

  - by Quaze

  So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

• Need help understanding _set_security_error_handler()

  - by Emil D

  So , I've been reading this article: http://msdn.microsoft.com/en-us/library/aa290051%28VS.71%29.aspx And I would like to define my custom handler.However, I'm not sure I understand the mechanics well.What happens after a call is made to the user-defined function ( e.g. the argument of _set_security_error_handler() ) ? Does the program still terminate afterward ? If that is the case, is it possible to terminate only the current thread(assuming that it is not the main thread of the application).AFAIK, each thread has its own stack , so if the stack of a thread gets corrupted, the rest of the application shouldn't be affected. Finally, if it is indeed possible to only terminate the current thread of execution, what potential problems could such an action cause? I'm trying to do all this inside an unmanaged C++ dll that I would like to use in my C# code.

• Intercept web requests from a WebView Flash plugin

  - by starkos

  I've got a desktop browser app which uses a WebView to host a Flash plugin. The Flash plugin makes regular requests to an external website for new data, which it then draws as fancy graphics. I'd like to intercept these web requests and get at the data (so I can display it via Growl, instead of keeping a desktop window around). But best I can tell, requests made by Flash don't get picked up by the normal WebView delegates. Is there another place I can set a hook? I tried installing a custom NSURLCache via [NSURLCache setSharedURLCache] but that never got called. I also tried method swizzling a few of the other classes (like NSCachedURLResponse) but couldn't find a way in. Any ideas? Many thanks!

• MySQL indexes: how do they work?

  - by bob-the-destroyer

  I'm a complete newbie with MySQL indexes. I have several MyISAM tables on MySQL 5.0x having utf8 charsets and collations with 100k+ records each. The primary keys are generally integer. Many columns on each table may have duplicate values. I need to quickly count, sum, average, or otherwise perform custom calculations on any number of fields in each table or joined on any number of others. I found this page giving an overview of MySQL index usage: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html, but I'm still not sure I'm using indexes right. Just when I think I've made the perfect index out of a collection of fields I want to calculate against, I get the "index must be under 1000 bytes" error. Can anyone explain how to most efficiently create and use indexes to speed up queries? Caveat: upgrading Mysql is not possible in this case. Using Navicat Light for db administration, but this app isn't required.
