  • How to get global access to enum types in C#?

    - by lala
    This is probably a stupid question, but I can't seem to do it. I want to set up some enums in one class like this: public enum Direction { north, east, south, west }; Then have that enum type accessible to all classes so that some other class could for instance have: Direction dir = north; and be able to pass the enum type between classes: public void changeDirection(Direction direction) { dir = direction; } I thought that setting the enum to public would make this automatically possible, but it doesn't seem to be visible outside of the class I declared the enum in.

  • Set Page Output Cache VaryByCustom value programmatically

    - by Chris Marisic
    I want to use an Enum value for the types of VaryByCustom parameters I will support, is it possible to do this? I tried setting it in the page itself <%@ OutputCache Duration="600" VaryByParam="none" VaryByCustom='<%=VaryByCustomType.IsAuthenticated.ToString(); %>' %> But this returned the entire literal string "<%=VaryByCustomType.IsAuthenticated.ToString(); %>" inside my global.asax is there any way to do this either on the page itself or from the codebehind? Or is this just something I have to accept is purely magic strings and nothing I can do to add type safety to it?

  • Embed Icons into WPF Application as Resource

    - by rattrick1
    I am trying to embed an icon into my my WPF application so that I can pull it out for use as an icon in the Window 7 JumpList using the following code: newScene.IconResourcePath = System.Reflection.Assembly.GetEntryAssembly().Location; newScene.IconResourceIndex = 0; I've gotten it to work using the following method: http://dennisdel.com/?p=38 However, it doesn't seem like the best approach and it seems like there should be an easier way to embed an icon resource into my application while still leaving the "Icon and Manifest" option checked in the Application properties for my program. I've tried numerous methods including setting the icon build action as a resource and an embedded resource, but every time I open my .exe in a resource editor, the icon does not appear. Any suggestions?

  • Codeigniter Form Validation - how to unset form values after success?

    - by BrynJ
    I realise this request goes against the example provided in the CI documentation (which advises a separate 'success' page view), but I would like to reutilise a given form view after a form has been successfully submitted - displaying a success message then displaying a blank form. I've tried a few ways unsuccessfully to clear the validation set values (unsetting $_POST, setting rules / fields to an empty array and rerunning validatio). I could redirect to the same page, but then I'd have to set a session variable to display a success message - which is a messy approach. Any ideas how to achieve the above?

  • With Rails 3 routes, how do you only allow a requests from 127.0.0.1?

    - by micah
    I'm writing an app where several of the routes should only be accessible from localhost. It looks like this is possible with the new routing system. http://www.railsdispatch.com/posts/rails-3-makes-life-better This has examples of restricting routes based on IP address, and setting up an IP address blacklist for your routes, but I'm interested in a whitelist with just one IP address. It would be cool if something like this worked: get "/posts" => "posts#show", :constraints => {:ip => '127.0.0.1'} But it didn't. Am I just missing the right syntax?

  • Embedding Python in C: Having problems importin local modules

    - by Drew
    I'm needing to run Python scripts within a C-based app. I am able to import standard modules from the Python libraries i.e.: PyRun_SimpleString("import sys") But when I try to import a local module 'can' PyRun_SimpleString("import can") returns the error msg: Traceback (most recent call last): File "", line 1, in ImportError: No module named can When I type the command "import can" in iPython, the system is able to find it. How can I link my app with can? I've tried setting PYTHONPATH to my working directory. Thanks.

  • alter mysqldump file before import

    - by julio
    Hi-- I have a mysqldump file created from an earlier version of a product that can't be imported into a new version of the product, since the db structure has changed slightly (mainly altering a column that was NOT NULL DEFAULT 0 to UNIQUE KEY DEFAULT NULL). If I just import the old dump file, it will error out since the column that has default values of 0 now breaks the UNIQUE constraint. It would be easy enough to either manually alter the mysqldump file, or import into a temp table and change it, then copy to the new table. However, is there a way to do this programatically, so it will be repeatable and not manual? (this will need to happen for many instances of this product). I'm thinking something like disabling key constraints for the import, then setting all values that = 0 to NULL, then re-enabling the key constraints? Is this possible? Any help appreciated.

  • UDF function with library dependencies on MySQL 5.1

    - by Fredrik
    I'm having a problem with a MySQL UDF function (mychem.sourceforge.net) that's dependent on a large library (openbabel.org) which is in turn plugin based. The problem is that the format plugins to openbabel doesn't seem to load in MySQL 5.1 and I suspect it might be due to the plugin_dir setting. I have set plugin_dir to /usr/lib/ which is the location for both libmychem.so and libopenbabel.so as well as the directory openbabel that contains the format plugins. Is there a way to turn off the plugin_dir restriction in MySQL (preferably without compiling MySQL from sources) so that I can test this hypothesis or do you have a different idea on what might cause the problem? All this is done on Ubuntu 10.04 (but I had the same kind of problems on 8.04, where I managed to get it working after a lot of steps that I unfortunately have forgotten...) I have turned off apparmor during testing and it doesn't help either.

  • Android: how can i tell if the soft keyboard is showing or not?

    - by binnyb
    Heres the dilemma: I am showing a screen with 3 input fields and 2 buttons inside of a tab(there are 3 tabs total, and they are on the bottom of the screen). the 2 buttons are set to the bottom left and right of the screen, right above the tabs. when i click on an input field, the tabs and buttons are all pushed up on top of the keyboard. i desire to only push the buttons up, and leave the tabs where they originally are, on the bottom. i am thinking of setting the visibility of the tabs to GONE once i determine that the soft keyboard is showing, and visibility to VISIBLE once the soft keyboard is gone. is there some kind of listener for the soft keyboard, or maybe the input field? maybe some tricky use of OnFocusChangeListener for the edit text? How can i determine whether the keyboard is visible or not?

  • How communicate with pty via minicom or screen?

    - by gscott2112
    I am trying to provide an AT/Modem-like interface around some hardware. Follwing this post I have the server setting up a pty using openpty(). Now I can communicate with the server as expected with a client app that open the slave and communicates via read() and write() calls. However I would also like to be able to use either the screen command or minicom to issue commands by hand to the slave. However the server never seems to receive any data when trying to do this. Is there something significant I am missing with this approach?

  • ASP.Net Vertical Menu with Scroll functionality

    - by Thomas
    Referring to Menu / Scrolling Example I would like to create / find the same functionality for a vertical menu. I tried the following. <asp:Menu ID="menuAccountMembers" runat="server" StaticSubMenuIndent="16px" Visible="true" RenderingMode="Table" ScrollDownImageUrl="~/Resources/scrolldown.jpg" ScrollUpImageUrl="~/Resources/scrollup.jpg"> <Items> But it doesnt display any scrolling images. I am using .net 4.0 Tried setting menuAccountMembers.RenderingCompatibility = new Version(3, 5); as well. If there a property to only display the first 5 root menu items, then show scroll bars for the rest? It can be click-able, no need to hover over to show next item.

  • Why is the dictionary debug visualizer less useful in Visual Studio 2010 for Silverlight debugging?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b"); EDIT: I've just tried the same debug in a Console app and it works as expected. The other project is a Silverlight 4 application, why are they different? Console Debug Screen Shot Silverlight 4 Debug Screen Shot:

  • How to change the default Help browser for VS2010?

    - by Scott Bilas
    Visual Studio 2010 changed the help system to run a little daemon and launch the system default web browser to view it. I'm using Firefox for my system browser but would like to use Chrome for VS help. Is there an option to change the Help browser that I'm not seeing in Tools|Options? If not, is there a workaround or registry setting to do this? As a backup I've been using H3Viewer but I'd like to be able to get context-sensitive F1 help from within the VS IDE.

  • Python unittest with expensive setup

    - by Staale
    My test file is basically: class Test(unittest.TestCase): def testOk(): pass if __name__ == "__main__": expensiveSetup() try: unittest.main() finally: cleanUp() However, I do wish to run my test through Netbeans testing tools, and to do that I need unittests that don't rely on an environment setup done in main. Looking at http://stackoverflow.com/questions/402483/caching-result-of-setup-using-python-unittest - it recommends using Nose. However, I don't think Netbeans supports this. I didn't find any information indicating that it does. Additionally, I am the only one here actually writing tests, so I don't want to introduce additional dependencies for the other 2 developers unless they are needed. How can I do the setup and cleanup once for all the tests in my TestSuite? The expensive setup here is creating some files with dummy data, as well as setting up and tearing down a simple xml-rpc server. I also have 2 test classes, one testing locally and one testing all methods over xml-rpc.

  • How can I ensure that JavaScript inserted via AJAX will be executed after the accompanying HTML (als

    - by RenderIn
    I've got portions of pages being replaced with HTML retrieved via AJAX calls. Some of the HTML coming back has JavaScript that needs to be run once in order to initialize the accompanying HTML (setting up event handlers). Since the document has already been loaded, when I replace chunks of HTML using jQuery's .html function, having jQuery(document).ready(function() {...}); doesn't execute since the page loaded long before and this is just a snippet of HTML being replaced. What's the best way to attach event handlers whose code is packaged along with the HTML it's interested in, when that content is loaded via AJAX? Should I just put a procedural block of javascript after the HTML , so that when I insert the new HTML block, jQuery will execute the javascript immediately? Is the HTML definitely in the DOM and ready to be acted upon by JavaScript which is in the same .html call?

  • Refresh index of full text search

    - by David
    Hi, in SQL Server 2008, when setting up a full text search, it gives me an option to choose a time/day for it to re-populate the index, can I do this from code instead like C# code? if so how would I do it? Would I need to execute SQL code from C# to refresh the index? Also, say if I DONT re-populate the index and add some new records, by using the FTS query will the new records still come up? But slower? Or will they not come up at all unless i reindex?

  • JSF - Updating Model Values in Controller Bean

    - by Sean
    I have a Controller bean (SearchController) that has two managed bean as managed properties (SearchCriteria, SearchResults; both of which are session scoped). When the user hits the find button, the action method that is executed is in SearchController. The SearchCreteria managed bean has a method called search(). This method returns a new SearchResults object. In the controller bean, I am setting the searchResults managed property to be this new SearchResults object. The searchResults object contains what I expect during that request, but the object does not persist in the managed bean. I understand that I am changing what object that searchResults is referencing, but what I don't understand is why JSF isn't updating the model to use the new object. Any ideas what I'm missing or don't understand? I am using JSF 1.1 on WebSphere 6.1. If I put the search method in the SearchResults managed bean, it works.

  • How do I change the JAVA_HOME for ant?

    - by Eugene M
    I'm doing java work on a class server where I don't have root. Whenever I try to compile using ant, it points to the wrong directory (/usr/tomcat instead of /usr/tomcat/jre ). One of the things we were told to do when setting up our user accounts was to add export JAVA_HOME=/usr/tomcat/jre to the .bashrc file. I don't know if that was supposed to take care of the problem but it doesn't seem to. So, how can I change the JAVA_HOME property for ant but only for when I run ant? EDIT: echo $JAVA_HOME points to /usr/tomcat/jre echo $JAVA_HOME\bin points to /usr/tomcat/jrebin The problem is when I normally run ant I get this error: Unable to locate tools.jar. Expected to find it in /usr/tomcat/lib/tools.jar Buildfile: build.xml compile: [javac] Compiling 1 source file to /home/ejm244/build/classes BUILD FAILED /home/ejm244/build.xml:9: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath.

  • Git: can I store known repositories along the repository?

    - by 0x6adb015
    I am setting up a Git repository. I know you can add repositories using git config --global, but is there a way that those known repositories gets cloned by users? The goal would be that once the repo gets cloned by userz, they can push to other repos just by their aliases. For example, I add git://X/mobility.git as X to the repo (somehow), a user clone it from git://Y, but then can do git push X without previously doing the git config. How to do that?

  • How to use C# nested structures to access tree of data

    - by zotty
    I'm importing some XML to C#, and want to be able to access data from the XML in the form of what I think is a nested structure. (I may be wrong!) What I have in my XML is in the following form: <hardwareSettings initial="true> <cameraSettings width="1024" height="768" depth="8" /> <tiltSettings theta="35" rho="90"> </hardwareSettings> I can import each setting alright, so I have them all in individual ints, but I would like to be able to access it in the form int x=hardwaresettings.camerasettings.width; int rho=hardwaresettings.tiltsettings.rho; I've tried various arrangements of structs within structs, but I don't seem able to cast a new object (hardwaresettings) that contains the appropriate children (camerasettings.width & tiltsettings.rho). Sorry if I'm not using the right lingo... I'm reading myself in circles here!

  • how do you load files in windows phone 7?

    - by matt
    do you seriously have to make your own content pipeline project for every single type of file you want to load? Microsoft just seem to be pretending that the iphone doesn't exist (even though they are now paying devs to port between them). I'm trying to port my game from the iphone to winmo7, and I already have a nice asset pipeline set up for exporting textures in the exact format we want (16 bit fmts ect) I just want to be able to open a file and read it, just like I would on any other platform. I have tried System.IO.File.OpenText("atextfile.txt"), but it says that function is "RESTRICTED!!!!" I have tried just adding the txt file to the content project, setting its properties to "content" and "copy always" and then trying to open it doing this.Content.Load("atextfile.txt"); with and without the extension, says it can't find the file.

Nothing has worked. Any ideas?
