• What's the .proto equivalent of List<T> in protobuf-net?

  - by Marc Bollinger

  To keep some consistency, we use code generation for a lot of our object models, and one of the offshoots of that has been generating the .proto files for ProtocolBuffers via a separate generation module. At this point though, I'm stumped at how to implement the generation for when it happens upon a List<T> object. It looks like this is possible via contracts: [ProtoMember(1)] public List<SomeType> MyList {get; set;} but outside of that, I'm not sure how or if it's possible to do this only from creating the .proto file/using the VS custom tool. Any thoughts?

• Where are events in Cocoa Touch?

  - by yesenin

  Hi all! I learn Cocoa Touch several days, and today have stuck while looking for way to implement a custom event. Event that I can see in Connection Inspector for my UIView subclass. What I have: There are a UILabel and MyView:UIView on MainVindow. MyView contains a UISlider. Interfaces for Controller and MyView // Controller.h @interface Controller : NSObject { IBOutlet UILabel *label; IBOutlet MyView *myView; } // I suppose that there should be something like -(IBAction) changeLabelValue for myView event @end // MyView.h @interface MyView : UIView { IBOutlet UISlider *slider; float value; } - (IBAction) changeValue; //for slider "Changed Value" event What I want: Add something in MyView that allows it to rise a event after change value. Can anybody help me? My main area in programming is .NET and I begin think that its terminology is not appropriate for this case. Thanks.

  - by Linda

  In my custom .master page I have the following code: <asp:ContentPlaceHolder id="PlaceHolderMain" runat="server" Visible="true" /> This prints out the main content of my page.

How would I change these values?

• debugging with internet explorer

  - by baiano

  I have some code that I thought I had written so that it would play nice on IE. But apparently it does not. I use IE8 for my testing and get quite frustrated with the built-in debugging 'tool'. I found that firebug has a javascript tool that debugs for IE but I have to click it for every page, wait for it to load and then test my script. Is there a way to make IE ALWAYS load the firebug .js file? I tried searching for way to set up a custom header file for my IE installation but was unsuccessful. Is there another tool out there that would be better/easier to use? Another way to test scripts for IE compatibility?

• sharepoint list relationship question

  - by Korey

  I have two custom lists in sharepoint with a one to many relationship on a column in both lists. So list A has text column 1 and list B has a lookup column 1' on list A's column 1. I want to display the rows in list A, where column 1 has a match on column 1' and a 2nd column in list B with a specific text string. I have Sharepoint Designer and am fumbling along with linked sources described here http://office.microsoft.com/en-us/sharepointdesigner/HA100991441033.aspx, but can't get exactly what I'm looking for.

• Is there a standard .NET exception to throw when a class doesn't implement a required attribute?

  - by a typing monkey

  Suppose I want to throw a new exception when invoking a generic method with a type that doesn't have a required attribute. Is there a .NET exception that's appropriate for this situation, or, more likely, one that would be a suitable ancestor for a custom exception? For example: public static class ClassA { public static T DoSomething<T>(string p) { Type returnType = typeof(T); object[] typeAttributes = returnType.GetCustomAttributes(typeof(SerializableAttribute), true); if ((typeAttributes == null) || (typeAttributes.Length == 0)) { // Is there an exception type in the framework that I should use/inherit from here? throw new Exception("This class doesn't support blah blah blah"); // Maybe ArgumentException? That doesn't seem to fit right. } } } Thanks.

• prevent _doPostBack getting rendered in button markup

  - by Christo Fur

  Hi Is it possible to prevent the _doPostBack() call getting rendered on a button? I would like add some custom logic prior to calling the postback. I have added an onClick event to the button e.g. <button id="manualSubmit" runat="server" class="manual-submit" onclick="$('#jeweller-form').hide();" /> However, this just gets rendered inline before the _doPostBack() But the postback gets fired before the jQueryHide takes place I would like to call my own JS function then manually trigger the postback any ideas?

• Need help converting apache .htaccess code to lighttpd url_rewrite code

  - by miCRoSCoPiC_eaRthLinG

  Hi All, I have this custom written CMS built on XAMPP. I'm trying to test the same on lighttpd to benchmark the so-called performance gains... but am stuck at the rewrite rules. I use the default rewrite rules of WordPress in my .htaccess which hands all url parsing over to my script as long as there aren't any files or directories same as the URL structure. Here's the code: RewriteBase /somedir/ # Let the Script handle all pretty URLs RewriteCond %{SCRIPT_FILENAME} !-d RewriteCond %{SCRIPT_FILENAME} !-f RewriteRule .* index.php [L] Can anyone please help me translate the same to the lighttpd format? I could only (partially) figure out the last line myself going through the lighty docs ... i.e. url.rewrite-once = ( ".*" => "index.php" ) But that of course won't suffice... All my CMS is doing is giving me 404's. Thanks, miCRoSCoPiC^eaRthLinG

• 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?

• DLL with JNA error looking up function?

  - by Thomas Nappo

  This is the code in my DLL (C#): http://pastebin.com/Uirn0z2V I have the DLL built and inside both the JDK bin folder along with inside my project. This is the Java code I am using to access with JNA: http://pastebin.com/NffpaEp8 Yet when I run my Java code this happens: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'Run': The specified procedure could not be found. at com.sun.jna.Function.<init>(Function.java:179) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:391) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:371) at com.sun.jna.Library$Handler.invoke(Library.java:205) at $Proxy0.Run(Unknown Source) at RunPETest.main(RunPETest.java:18) I have no experience with using JNA with custom DLLs or creating DLLs with C#... so I'm stuck here.

• GUI Framework for flash (as3)

  - by widgisoft

  I can't seem to find any GUI framework's for as3 that are as good as any the applications I already see out on the web; Is this something most people code themselves or am I missing something in flash itself? I'm looking for dialogs/windows, buttons, text boxes, combos, drop downs, menus, etc etc and the ability to extend the components to make new ones. I'd also prefer it to be as3 but any others will do also. May need to elaborate a little.. I'm actually looking for a framework to allow me to create my own GUIs in flash, custom skins, colors, styles, etc.

• Colouring JTree's TreeNodes

  - by Amadan

  I have a JTree which I give objects that implement the TreeNode interface, and a custom TreeModel to display them (not using DefaultMutableTreeNode). I would like to change the text colour of some nodes. I can't find anything in the docs, except javax.swing.tree.DefaultTreeCellRenderer.setTextNonSelectionColor(Color newColor), but it will change everything indiscriminately, and I only need it for some nodes (specifically, broken links, i.e. nodes whose corresponding files can't be found on the disk, should be greyed out, the rest should be default). Can it be done, and how?

• 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?

• How do I override ToString in C# enums?

  - by scraimer

  In the post Enum ToString, a method is described to use the custom attribute DescriptionAttribute like this: Enum HowNice { [Description("Really Nice")] ReallyNice, [Description("Kinda Nice")] SortOfNice, [Description("Not Nice At All")] NotNice } And then, you call a function GetDescription, using syntax like: GetDescription<HowNice>(NotNice); // Returns "Not Nice At All" But that doesn't really help me when I want to simply populate a ComboBox with the values of an enum, since I cannot force the ComboBox to call GetDescription. What I want has the following requirements: Reading (HowNice)myComboBox.selectedItem will return the selected value as the enum value. The user should see the user-friendly display strings, and not just the name of the enumeration values. So instead of seeing "NotNice", the user would see "Not Nice At All". Hopefully, the solution will require minimal code changes to existing enumerations. Obviously, I could implement a new class for each enum that I create, and override its ToString(), but that's a lot of work for each enum, and I'd rather avoid that. Any ideas? Heck, I'll even throw in a hug as a bounty :-)

• Wicket : Can a Panel or Component react on a form submit without any boilerplate code?

  - by MRalwasser

  I am currently evaluating Wicket and I am trying to figure out how things work. I have a question regarding form submit and panels (or other components). Imagine a custom wicket panel which contains a text field, doing as-you-type validation using ajax. This panel is added to a form. How can the Panel react a form submit (let's say because javascript/ajax is unavailable)? I am currently only aware of one solution: calling a panel's method inside the Form onSubmit() method. But this seems not like a "reusable" approach here, because I have to add boilerplate code to every form's onSubmit() which contains the panel (and every developer which use the panel must know this). So here comes my question: Is there any way that a Panel/Component can "detect" a form submit in some way? Or is there any other solution beside this? Thank you.

• 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?

• 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

• How to allow users to select their own grouping for a .NET TreeView control

  - by Chapso

  I am using a treeview to display projects, tasks, time entries, and the people who are working on a project. I would like to allow the user to define a custom grouping (ie. Project->Task->Time Entries or Project->Date (of time entry)->Task->TimeEntry). The relevant groups would be Project, Task, Time Entry, and Person, with some metadata from them. I want to have some modular way to allow a user to specify how they would like to display the information. Does anyone know of a good method by which this can be done? I currently have hard-coded a display which looks like this: Project Task Time Entry Next Project ... My thought is to do something like write methods to display each type and somehow let a user select what order the display would group. Please let me know if I am not being clear enough.

• Consuming all touchEvents not preventing scrolling on the blackberry storm

  - by Some guy with a headache

  Hello, I am trying to make a custom control for the BlackBerry Storm using SDK v5.0. This control needs to disable scrolling while the user is dragging elements within a field. The problem is that even if I my control consumes every single touch event send to it, when the user lifts their finger off the screen it still flings up or down as if its finishing a scroll action. Does anyone know of a way to prevent this from happening or what I might be doing wrong ? Thank you.

• SSIS Script Component Testing Strategy

  - by Paul Kohler

  This question is in respect to the script component specifically. I am aware of ssisUnit etc… With simple SSIS Scripts Components, it’s sufficient to let basic testing flesh out issues, however I am working with a script that has grown in complexity over time. To better test the functionality I am considering abstracting the script logic into a DLL that gets deployed with the package, and then use the custom component in the script. The advantage is that the function will be more testable etc but it’s one more deployment artefact that needs to be managed. My question is, does anyone know of a better way to test such an SSIS script in a more isolated manner than to run the whole package and examine the output?

• How to generate one large dependency map for the whole project that builds with makefiles?

  - by Stan

  I have a gigantic project that is built using makefiles. Running make at the root of the project takes over 20 minutes when no files have changed (i.e. just traversing the project and checking for updated files). I'd like to create a dependency map that will tell me which directories I need to run 'make' in based on the file(s) changed. I already have a list of updated files that I can get from my version control system, and I'd like to skip the 20 minutes of traversing and get straight to the locations that do need to be recompiled. The project has a mix of several languages and custom tools, so this would ideally be language-independent (i.e. it would only process all makefiles to generate dependencies). I'll settle for a C/C++-specific solution, too, as the majority of the project is in C++. The project is built on Linux.

• With wordpress, is there a statement like current_user_can except show something if a user does not

  - by zac

  I am trying to show a custom css depending on user permissions with a function like : <?php if ( !current_user_can( 'install_themes' ) ) { ?> <link media="all" type="text/css" href="<?php bloginfo( 'template_directory' ); ?>/library/styles/customAdmin.css" rel="stylesheet"> <?php } Perhaps I am being dense about this but I want to do the reverse and show specific CSS if a user can not, in this case, install_themes. I am doing it this way because the css hides parts of the admin area that I do not want hidden globally. I could probably do this with liberal use of !important in my style sheetsbut I was hoping there was an easier way to write this in the function. Or is there a way to write <?php if ( current_user_can('level_7') ) : ?> with something like if < level_7 ?

• How to order the images in a mysql database?

  - by user305270

  Hy! Here is my problem: i have a profile and this profile has for example 100 images. When someone visit this profile the first image will be the first result of my query that sorts by updated_at. But if the user would want to put the image with the (id = 8) to be the first, then (id = 22) then (id = 88) and so on? I need to put another field or is really necessary a new table to make a custom sort on images? and maybe someone explain this to me how to do? thanks, i appreciate your help ;)

• ASP.NET MVC - Alternative to Role Provider?

  - by ebb

  Hey there, I'm trying to avoid the use of the Role Provider and Membership Provider since its way too clumsy in my opinion, and therefore I'm trying to making my own "version" which is less clumsy and more manageable/flexible. Now is my question.. is there an alternative to the Role Provider which is decent? (I know that I can do custom Role provier, membership provider etc.) By more manageable/flexible I mean that I'm limited to use the Roles static class and not implement directly into my service layer which interact with the database context, instead I'm bound to use the Roles static class which has its own database context etc, also the table names is awful.. Thanks in advance.
