  • Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

    - by ben
    I have hard times using maven to generate my client. So Please refer to http://stackoverflow.com/questions/2131001/creating-a-web-service-client-directly-from-the-source for the first part of my question. To keep it simple and short, I want to go from here (a file in src/main/java) : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } to there : /** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.1.7-b01- * Generated source version: 2.1 * */ @WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/") public class HelloService extends Service { private final static URL HELLOSERVICE_WSDL_LOCATION; private final static Logger logger = Logger.getLogger(com.example.wsimport.HelloService.class.getName()); ...etc using only 1 pom.xml file. Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

  • Server reporting incorrect mime type for css files

    - by Becky
    We have a VPS server that we host our websites on. I have written a CMS using CodeIgniter. On one of the interfaces, I am attempting to upload a css file to the system. This worked correctly when we had it hosted on shared hosting. Since we've moved it to the VPS, I am getting an "incorrect filetype" error. It all comes down to the fact that the server is reporting a mime type of text/x-c for the css file rather than text/css. I logged in via shell and ran the following command on an existing valid css file (to make sure it wasn't an issue with either CodeIgniter or with php). file --brief --mime 'filename.css' 2>&1 The server gave me the following in response to my command: text/x-c; charset=us-ascii My question ... is there some sort of server setting that I need to tweak to get the server to correctly identify the css file as text/css? Do I just have to add a mime type for the css files to the server? I found the mime types file (etc/mime.types), and it just hase video types and a couple other that I have no idea what they are. There is nothing in there for css or images or html files. Unless I'm looking in the wrong spot. I'm not a server person, so I'm hoping someone can help me out. Some server specs: Apache/2.2.22 (Unix) php 5.3.13 Server API = CGI/FastCGI the fileinfo php extension appears to be disabled

  • FOR BOUNTY: "QFontEngine(Win) GetTextMetrics failed ()" error on 64-bit Windows

    - by David Murdoch
    I'll add a large bounty to this when Stack Overflow lets me. I'm using wkhtmltopdf to convert HTML web pages to PDFs. This works perfectly on my 32-bit dev server [unfortunately, I can't ship my machine :-p ]. However, when I deploy to the web application's 64-bit server the following errors are displayed: C:\>wkhtmltopdf http://www.google.com google.pdf Loading pages (1/5) QFontEngine::loadEngine: GetTextMetrics failed () ] 10% QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngine::loadEngine: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngine::loadEngine: GetTextMetrics failed () ] 36% QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () // ...etc.... and the PDF is created and saved... just WITHOUT text.

Server information: Windows edition: Windows Server Standard Service Pack 2 Processor: Intel Xeon E5410 @ 2.33GHz 2.33 GHz Memory: 8.00 GB System type: 64-bit Operating System Can anyone give me a clue as to what is happening and how I can fix this? Also, I wasn't sure what to tag/title this question with...so if you can think of better tags/title comment them or edit the question. :-)

  • Source of parsers for programming languages?

    - by Arkaaito
    I'm dusting off an old project of mine which calculates a number of simple metrics about large software projects. One of the metrics is the length of files/classes/methods. Currently my code "guesses" where class/method boundaries are based on a very crude algorithm (traverse the file, maintaining a "current depth" and adjusting it whenever you encounter unquoted brackets; when you return to the level a class or method began on, consider it exited). However, there are many problems with this procedure, and a "simple" way of detecting when your depth has changed is not always effective. To make this give accurate results, I need to use the canonical way (in each language) of detecting function definitions, class definitions and depth changes. This amounts to writing a simple parser to generate parse trees containing at least these elements for every language I want my project to be applicable to. Obviously parsers have been written for all these languages before, so it seems like I shouldn't have to duplicate that effort (even though writing parsers is fun). Is there some open-source project which collects ready-to-use parser libraries for a bunch of source languages? Or should I just be using ANTLR to make my own from scratch? (Note: I'd be delighted to port the project to another language to make use of a great existing resource, so if you know of one, it doesn't matter what language it's written in.)

  • xp_smtp_sendmail blank space added to html randomly

    - by Igor Timofeyev
    I have a proc where I generate small html doc with a link and send it out via xp_smtp_sendmail proc. Link is generated based on query results and is long. This works in most cases. However, sometimes the link gets broken due to spaces being inserted into querystring variable names, i.e. &Na me=John. This might vary between email clients(same link works in Gmail, but might not work in comcast due to spaces. The space seems to be randomly inserted, so in each broken email link space might break other querystring variables. When I do PRINT from proc the link is clean, no spaces. Here's my sample of the mail proc being executed within main proc(that gets query results and generates html for @Message). The space seems to be inserted regardless of whether I encode the url or not. Thank you in advance for your help. I can send a cleaner version of the code if it's not displayed properly here. ....query results above SET @Message = NULL SET @Message = @Message + + '<br/>Dear ' + @FirstName + ' ' + @LastName + ',' + '<br/><br/>Recently you took "' + @Title + '".

  • ASP.Net MVC: "Random" URLs getting generated by URL.Action

    - by Daniel Magliola
    I have 2 very similar routes, just because i'm trying to generate two different URLs for the same resource (same Controller/Action), and both are very similar. These are the routes definitions: routes.MapRoute("Post2.Mp3", "sites/{siteSlug}/post/{brand}/aconstant-{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[^(aconstant\-)][A-Za-z0-9-_]+", brand = @"[A-Za-z0-9-_]+" }); routes.MapRoute("Post.Mp3", "sites/{siteSlug}/post/{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[A-Za-z0-9-_]+" }); "brand" is going to be my site name, which is the same as "aconstant" in those routes. Now, if I try this: Url.Action("ShowMp3", "Posts", new { siteSlug = post.Site.Slug, slug = post.Slug, origin = "origfeedwithaudio", brand = "aconstant" }) sometimes I get the URL I expect: /sites/site-Name/post/aconstant/aconstant-post-Name.mp3 but sometimes, I get this: /sites/site-Name/post/post-Name.mp3?brand=aconstant By sometimes, I mean that different sets of "slugs" give me one or the other. I haven't seen the same set of slugs give me different URLs. I haven't found any reasonable rule for when i'm getting one or the other, it seems random. What is going on here? How can I be getting different URLs based on esentially the same arguments? Thanks! Daniel

  • CSS animated menu

    - by Andrea
    I am trying to obtain something similar to the "share this on..." menu here but I don't quite understand how they are doing this, even after a look at their CSS. I refer to the fact that the images show up on hover. My first attempt would be something like <div id="share_on"> <ul> <li><a href="#"><img src="shareon-digg.png" /></a></li> <li><a href="#"><img src="shareon-reddit.png" /></a></li> ... <li><a href="#"><img src="shareon-stumbleupon.png" /></a></li> </ul> </div> and the CSS: #share_on {overflow: hidden} #share_on ul {margin-bottom: -16px} #share_on li {display: inline} #share_on li:hover {margin-top: -16px} Of course this does not work, which is why I am asking here. In the inactive state, only half of the icon shows up, which is the expected behaviour. But on hover, nothing changes. I also have tried some variations, like #share_on li:hover {margin-bottom: 16px} or #share_on li:hover {padding-bottom: 16px} but none of these works. Any ideas?

  • Is a VCS appropriate for usage by a designer?

    - by iconiK
    I know that a VCS is absolutely critical for a developer to increase productivity and protect the code, no doubts about it. But what about a designer, using say, Photoshop (though it's not specific to any tools, just to make my point clearer). VCSs uses delta compression to store different versions of files. This works very well for code, but for images, that's a problem. Raster image files are binary formats, though vector image files are text (SVG comes to my mind) and pose to problem. The problem comes with .psd files (and any other image "source" file) - those can get pretty big and since I'm not familiar with the format, I'll consider them as binary files. How would a VCS work in this condition? The repository could be pretty darned big if the VCS server isn't able to diff the files efficiently (or worse, not at all) and over time this can become a really big pain when someone needs to check out the repository (or clone it if using a DVCS). Have any of you used a VCS for this purpose? How well does it work? I'm mostly interested in Mercurial, though this is a general situation that applies to any VCS.

  • Building error in Eclipse with build.xml

    - by Zachary
    I am working on a Java project with Eclipse. This project requires a second project (not mine), named sams in its build-path. The sams is provided with a build.xml file and it should generate some code using Apache CXF when building it. When I use Apache ANT on Eclipse and run the cxf.generated command from its build file I get the following error: Buildfile: C:\Docs\ZacRocha\Desktop\sams\build.xml cxf.generated: [echo] Generating code using Apache CXF wsdl2java...

  • Simulate Windows Service with ASP.NET

    - by Bayonian
    Hi, I have small web app that generate PDF files as a report. I'm trying to delete those generated PDF files after 10 sec that they are generated. What I want to do is to read a folder with PDF files every 10 sec, and delete all the PDF files inside that folder. I read this post of Easy Background Tasks in ASP.NET. The following code is the VB version. Protected Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) AddTask("DoStuff", 10) End Sub Private Sub AddTask(ByVal name As String, ByVal seconds As Integer) OnCacheRemove = New CacheItemRemovedCallback(CacheItemRemoved) HttpRuntime.Cache.Insert(name, seconds, Nothing, DateTime.Now.AddSeconds(seconds), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, _ OnCacheRemove) End Sub Public Sub CacheItemRemoved(ByVal k As String, ByVal v As Object, ByVal r As CacheItemRemovedReason) ' do stuff here if it matches our taskname, like WebRequest DeletePDFilesInFoler() ' re-add our task so it recurs AddTask(k, Convert.ToInt32(v)) End Sub But I got this error Delegate 'System.Web.Caching.CacheItemRemovedCallback' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor. If this code works, where I should put it. Right, now I'm putting it in the master page. How to get this error out? Thank you

  • QT- QImage and multi-threading problem.

    - by umanga
    Greetings all, Please refer to image at : http://i48.tinypic.com/316qb78.jpg We are developing an application to extract cell edges from MRC images from electron microscope. MRC file format stores volumetric pixel data (http://en.wikipedia.org/wiki/Voxel) and we simply use 3D char array(char***) to load and store data (gray scale values) from a MRC file. As shown in the image,there are 3 viewers to display XY,YZ and ZX planes respectively. Scrollbars on the top of the viewers use to change the image slice along an axis. Here is the steps we do when user changes the scrollbar position. 1) get the new scrollbar value.(this is the selected slice) 2) for the relavant plane (YZ,XY or ZX), generate (char* slice;) array for the selected slice by reading 3D char array (char***) 3) Create a new QImage* (Format_RGB888) and set pixel values by reading 'slice' (using img-setPixel(x,y,c);) 4) This new QImage* is painted in the paintEvent() method. We are going to execute "edge-detection" process in a seperate thread since it is an intensive process.During this process we need to draw detected curve (set of pixels) on top of above QImage*.(as a layer).This means we need to call drawPoint() methods outside the QT thread. Is it the best wayto use QImage for this case? What is the best way to execute QT drawing methods from another thread? thanks in advance,

  • Uploadify and rails 3 authenticity tokens

    - by Ceilingfish
    Hi chaps, I'm trying to get a file upload progress bar working in a rails 3 app using uploadify (http://www.uploadify.com) and I'm stuck at authenticity tokens. My current uploadify config looks like <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $("#zip_input").uploadify({ 'uploader': '/flash/uploadify.swf', 'script': $("#upload").attr('action'), 'scriptData': { 'format': 'json', 'authenticity_token': encodeURIComponent('<%= form_authenticity_token if protect_against_forgery? %>') }, 'fileDataName': "world[zip]", //'scriptAccess': 'always', // Incomment this, if for some reason it doesn't work 'auto': true, 'fileDesc': 'Zip files only', 'fileExt': '*.zip', 'width': 120, 'height': 24, 'cancelImg': '/images/cancel.png', 'onComplete': function(event, data) { $.getScript(location.href) }, // We assume that we can refresh the list by doing a js get on the current page 'displayData': 'speed' }); }); </script> But I am getting this response from rails: Started POST "/worlds" for 127.0.0.1 at 2010-04-22 12:39:44 ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (6.6ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (12.2ms) This appears to be because I'm not sending the authentication cookie along with the request.

  • ASP.NET MVC - PartialView not refreshing

    - by Billy Logan
    Hello Everyone, I have a view that uses a javascript callback to reload a partial view. For whatever reason the contents of the partial class do not refresh even though i can step through the entire process and see the page being recalled and populated. Any reason why the page would not display? Code is as follows: <div id="big_image_content"> <% Html.RenderPartial("ZoomImage", Model); %> </div> This link should reload the div above: <a href="javascript:void(0)" onclick="$('#big_image_content').load('/ShopDetai/ZoomImage);" title="<%= shape.Shape %>" alt="<%= shape.Shape %>"> <img src="http://images.rugs-direct.com/<%= shape.Image.ToLower() %>" width="40" alt="<%= shape.Shape %>"> </a> partial view(ZoomImage.ascx) simplified for now, but still doesn't load: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<RugsDirect.Data.ItemDetailsModel>" %> <%= Model.Category.ToLower()%> And finally the controller side of things: public ActionResult ZoomImage() { try { ItemDetailsModel model = GetMainImageContentModel(); return PartialView("ZoomImage", model); } catch (Exception ex) { //send the error email ExceptionPolicy.HandleException(ex, "Exception Policy"); //redirect to the error page return RedirectToAction("ViewError", "Shop"); } } Again, i can step through this entire process and all seems to be working accept for the page not reloading. I can even break on the <%= Model.Category.ToLower()% of the partial view, but it will not be displayed. Thanks in advance, Billy

  • correct fisheye distortion

    - by Will
    I have some points that describe positions in a picture taken with a fisheye lens. I've found this description of how to generate a fisheye effect, but not how to reverse it. How do you calculate the radial distance from the centre to go from fisheye to rectilinear? My function stub looks like this: Point correct_fisheye(const Point& p,const Size& img) { // to polar const Point centre = {img.width/2,img.height/2}; const Point rel = {p.x-centre.x,p.y-centre.y}; const double theta = atan2(rel.y,rel.x); double R = sqrt((rel.x*rel.x)+(rel.y*rel.y)); // fisheye undistortion in here please //... change R ... // back to rectangular const Point ret = Point(centre.x+R*cos(theta),centre.y+R*sin(theta)); fprintf(stderr,"(%d,%d) in (%d,%d) = %f,%f = (%d,%d)\n",p.x,p.y,img.width,img.height,theta,R,ret.x,ret.y); return ret; }

  • Mac, PDFKit, PDF/X

    - by PhillipeTKern
    I'm in need of generating and viewing PDF/X-1a. After spending quite some time I came to the conclusion that the only way (hopefully someone will prove me wrong) to achieve this is to use Cocoa. More context: I need to generate PDF/X-1a, that is, all the fonts embeded, spot colors, overprint, ... preferably from Python. But the only libraries which support such things are iText and perhaps and Apache FOP. The first one could be used with Jython, which is ok but not optimal. But then, I simply could not find any viable viewer. Poppler, xpdf, Sumatra, mupdf, ghostscirpt - all of them - just cannot handle large CMYK pdfs, lots of text, ... I really would like to use open sourced libraries but unfortuntatelly the only option I see right now is to buy Mac as I saw one could print (Save-as) to built-in PDF printer under PDF/X conformance and I expect Preview to be comparable, if not better, to Acrobat. But I'm not sure if is it even possible to programmatically access the MacOS libraries responsible for generating PDF? I'm asking because I heard not everything from MacOS is available via public API... (And what Python goes, I thought I could use PyObjC..?) Any others ideas are of course very welcomed!

  • Best Practices for Setup and Management of an Open Source Project

    - by VirtuosiMedia
    Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

  • Maintain aspect ratio on browser window resize?

    - by Anthony
    I have a simple page with images, and when the user clicks the image, it opens up a new browser window with the image filling the area. I have the css set on the new window so that the image height and width are both 100% (and overflow is set to hidden) so that the window can be resized. But what I need is for the window to maintain aspect ratio if the user resizes it. Right now, I'm stuck because I'm not getting how the event works, but I think I'm making this harder than it needs to be. Right now I have: $(function(){ $(window).resize(function() { var height = $(this).attr("innerHeight"); var width = $(this).attr("innerWidth"); if(height/width != .75){ window.resizeTo(width,width*.75); } }); }); Before I added the conditional, the window would immediately start shrinking (apparently opening a new window fires the resize event). Adding the conditional preventing this from happening when the window opens, but any resizing starts the shrinking again. Is it just because the height and width are never exactly the right ratio (should I manually set the width to a round number ever time) or is there something else I'm doing wrong? Or is there some other way to get what I'm after that's more straightforward?

  • Access Violation When Writing Dynamic 2D Array... Sometimes

    - by Shraptnel
    This program is meant to generate a dynamic array, however it gives an access violation error when writing when given certain dimensions. Eg: R = 6, C = 5 crashes, but then R = 5, C = 6 doesn't. In case your wondering, it isn't my homework to "fix" this broken program, this is the method we were taught in class. Also part of my assessment is to use this method, so vectors are out. Thanks in advance! #include <iostream> using namespace std; int main(){ const int R = 6; const int C = 5; char **d; d = new char *[R]; for(int i=0; i<C; ++i){ d[i] = new char[C]; } //initialise for(int i=0; i<R; ++i){ for(int j=0; j<C; ++j){ d[i][j] = 'd'; cout<<d[i][j]; } cout<<endl; } cout<<endl; system("pause"); return 0; }

  • Raytraced Shadows Problem

    - by Mat
    Hey There! I've got a problem with shadowrays in my raytracer. Please have a look at the following two pictures 3D sMax: My Raytracer: The scene is lit by a very bright light, shining from the back. It's so bright that there is no gradient in the shading, just either white or dark (due to the overexposure). both images were rendered using 3DStudioMax and both use the exact same geometry, just in one case the normals are interpolated across the triangles. Now consider the red dot on the surface. In the case of the unsmoothed version, it lies in a dark area. this means that the light source is not visible from this triangle, since it's facing away from it. In the smoothed version however, it lies in the lit area, because the interpolated normal would suggest, that the light would be visible at that point (although the actual geometry of the triangle is facing away from the lightsource). My problem now is when raytraced shadows come in. if a shadowray is shot into the scene, from the red dot, to test whether the light-source is visible or not (to determine shadowing), the shadowray will return an intersection, independent of whether normals are interpolated or not (because intersections only depend on the geometry). Therefore the pixel would be shaded dark. 3dsamx is handling the case correctly - the rendered image was generated with Raytraced shadows turned on. However, my own Raytracer runs exactly into this problem when i turn on raytraced shadows (in my raytracer, the point is dark in both cases, because raytraced shadows determine the point lying in the shadow), and i don't know how to solve it. I hope someone knows this problem and how to deal with it.. thanks!

  • accelerating Wheel - psychtoolbox in matlab

    - by ariel
    Hi I am trying to write a code that will show an acceleration wheel. as long as the user press 'a' the wheel should accelerate counterclock wize. the thing is that it turn in the right direction but it doesn't accelerate. This is the code I am using . PTB-3 windows XP. img=imread('c:\images.jpg'); [yimg,ximg,z]=size(img); rot_spd = 1; larrow = KbName('a'); % modify this for Windows rarrow = KbName('b'); [w,rect]=Screen('OpenWindow',0,[0 0 0]); sx = 400; % desired x-size of image (pixels) sy = yimg*sx/ximg; % desired y-size--keep proportional t = Screen('MakeTexture',w,img); bdown=0; th = 0; % initial rotation angle (degrees) HideCursor while(~any(bdown)) % exit loop if mouse button is pressed [x,y,bdown]=GetMouse; [keyisdown,secs,keycode] = KbCheck; if(keycode(larrow)) th = th - rot_spd-1; % accelerate counterclockwise th end if(keycode(rarrow)) th = th + rot_spd+1; % accelerate clockwise th end destrect=[x-sx/2,y-sy/2,x+sx/2,y+sy/2]; Screen('DrawTexture',w,t,[],destrect,th); Screen('Flip',w); end Screen('Close',w) ShowCursor If anyone has an odea why it doesn't accelerate I'd appriciate it very much.

  • Find unique vertices from a 'triangle-soup'

    - by sum1stolemyname
    I am building a CAD-file converter on top of two libraries (Opencascade and DWF Toolkit). However, my question is plattform agnostic: Given: I have generated a mesh as a list of triangular faces form a model constructed through my application. Each Triangle is defined through three vertexes, which consist of three floats (x, y & z coordinate). Since the triangles form a mesh, most of the vertices are shared by more then one triangle. Goal: I need to find the list of unique vertices, and to generate an array of faces consisting of tuples of three indices in this list. What i want to do is this: //step 1: build a list of unique vertices for each triangle for each vertex in triangle if not vertex in listOfVertices Add vertex to listOfVertices //step 2: build a list of faces for each triangle for each vertex in triangle Get Vertex Index From listOfvertices AddToMap(vertex Index, triangle) While I do have an implementation which does this, step1 (the generation of the list of unique vertices) is really slow in the order of O(n!), since each vertex is compared to all vertices already in the list. I thought "Hey, lets build a hashmap of my vertices' components using std::map, that ought to speed things up!", only to find that generating a unique key from three floating point values is not a trivial task. Here, the experts of stackoverflow come into play: I need some kind of hash-function which works on 3 floats, or any other function generating a unique value from a 3d-vertex position.

  • TRibbon's large button's image is not centered...any ideas? easy to demonstrate at design-time.

    - by X-Ray
    i'm using delphi 2009 (updates 1, 2, 3, 4). i'm seeing something quite peculiar. the image on the button is not centered in the button when i have a large button with a large glyph! rather than being centered, the left part of the glyph starts at the center of the button. a clue is that when i: go into the action editor and select the action use the ImageIndex combobox in the object inspector, the list is empty (normally i'd see the available images in the combobox). it seems as though there's an image width property i've failed to set or an imagelist not correctly configured. i've expected the glyph on a large button should be 32x32. try the following: paste these components into an empty form add a 32x32 image to the image list set the Action1 imageindex to 0 you'll immediately see what i mean! can anyone tell me why it looks that way? i find it interesting that the ribbon demo app doesn't show this problem. i even tried the same image. thank you! object ActionManager1: TActionManager ActionBars = < item Items = < item Action = Action1 Caption = '&Action1' ImageIndex = 0 CommandProperties.ButtonSize = bsLarge end> ActionBar = RibbonGroup1 end> LargeDisabledImages = img3232 LargeImages = img3232 Left = 376 Top = 184 StyleName = 'Ribbon - Luna' object Action1: TAction Caption = 'Action1' ImageIndex = 0 end end object Ribbon1: TRibbon Left = 0 Top = 0 Width = 693 Height = 147 ActionManager = ActionManager1 Caption = 'Ribbon1' Tabs = < item Caption = 'RibbonPage1' Page = RibbonPage1 end> ExplicitLeft = 232 ExplicitTop = 80 ExplicitWidth = 0 DesignSize = ( 693 147) StyleName = 'Ribbon - Luna' object RibbonPage1: TRibbonPage Left = 0 Top = 54 Width = 692 Height = 93 Caption = 'RibbonPage1' Index = 0 object RibbonGroup1: TRibbonGroup Left = 4 Top = 3 Width = 54 Height = 86 ActionManager = ActionManager1 Caption = 'RibbonGroup1' GroupIndex = 0 end end end object img3232: TImageList Height = 32 Width = 32 Left = 376 Top = 256 end

  • WCF: WTF! Does WCF raise the bar or just the complexity level?

    - by rp
    I understand the value of the three-part service/host/client model offered by WCF. But is it just me or does it seem like WCF took something pretty direct and straightforward (the ASMX model) and made a mess out of it? Is there an alternative to using SvcUtil's command line step back in time to generate the proxy? With ASMX services a test harness was automatically provided; is there a good alternative today with WCF? I appreciate that the WS* stuff is more tightly integrated with WCF and hope to find some payoff for WCF there, but geeze, otherwise I'm perplexed. Also, the state of books available for WCF is abysmal at best. Juval Lowy, a superb author, has written a good O'Reilly reference book "Programming WCF Services" but it doesn't do that much (for me anyway) for learning now to use WCF. That book's precursor (and a little better organized, but not much, as a tutorial) is Michele Leroux Bustamante's Learning WCF. It has good spots but is outdated in place and its corresponding Web site is gone. Do you have good WCF learning references besides just continuing to Google the bejebus out of things? Thanks, rp
