Resources and class librariesI'm trying to embed a js file in my class library and register it in an aspx. I created the most simple solution I could : + ClassLibrary1 : - Class1.cs - test.js (embedded resource) +WebSite - Default.aspx The page is displayed correctly with the resource url : /WebSite2/WebResource.axd?d=xnJEzCL_Wi5ffEYd13hU2ywYJr-rFccyB13UatbX-2Q1&t=632713812869876368 When I copy/paste this link in my browser, I get a blank page. This mechanism works for the .NET framework and not for my projet, that's weird. I'm using VS Team Suite : 8.0.50727.42 (RTM.050727-4200) ..NET Frameword 2.0.50727 Could it be a question of authorization? Thanks, Fred -------------------------------------- Content of class1.cs [assembly: System.Web.UI.WebResource("test.js", "application/x-javascript")] namespace ClassLibrary1 { public class Class1 : WebControl { protected override void CreateChildControls() { base.CreateChildControls(); Literal l = new Literal(); l.Text = Page.ClientScript.GetWebResourceUrl(this.GetType(), "test.js"); Controls.Add(l); } } } Are you using a control that derives further from Class1? When you call this.GetType()
it's getting the most derived type which is not necessarily the class calling GetType(). In this scenario, it's safer to use type(Class1). Though, I suspect that is not your problem. Oh, I reread your post... Try looking at the source code when you get the blank page. I bet it's your javascript in there. -Brock DevelopMentor http://staff.develop.com/ballen Show quoteHide quote > Hi, > > I'm trying to embed a js file in my class library and register it in > an aspx. > > I created the most simple solution I could : > + ClassLibrary1 : > - Class1.cs > - test.js (embedded resource) > +WebSite > - Default.aspx > The page is displayed correctly with the resource url : > /WebSite2/WebResource.axd?d=xnJEzCL_Wi5ffEYd13hU2ywYJr-rFccyB13UatbX-2 > Q1&t=632713812869876368 > > When I copy/paste this link in my browser, I get a blank page.

The code of the blank page is a blank page, not my javascript file: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD> <BODY></BODY></HTML> I have the EXACT problem. I cannot find an answer.
All of the examples tell us to: 1. Embed your resources Done: I know I have done it correctly because I can extract the resource at runtime manually 2. Add a WebResourceAttribute to your assembly Done: [assembly: WebResource("image1.jpg", "image/jpeg")] 3. Use GetWebResourceUrl from the aspx page Done: Page.ClientScript.GetWebResourceUrl(typeof(AssemblyWithWebResources.MyClass), "image1.jpg"); 4. Use the generated URL to retreive the image Fails! No content. The embeddedresource URLs NEVER return any content! I know I am doing it correctly, because if I do it any differently (like using namespaces with the resource name) I get all kinds of Errors, but if I do it the right way, there are no errors: just zero content. Somebody please help, we are desparate! I have boiled it down as simple as possible. Feel free to have a look at: http://fluidnature.com/test/TestOfWebResources.zip It has 3 projects: 1. AssemblyWithWebResources - contains an empty class and embedded resources exposed with WebResourceAttributes 2. TestWebSite - default page generates the web resource URLs and extracts the actual embedded data so you can compare the results 3. AssemblyWithWebResources_UnitTests - uses NUnitASP.dll to unit test the page results. Each URL is returned to the client, the UnitTests try to open each URL and make sure they are not empty. They fail. - To test, you must first update the config file with the location of the test page on your local webserver. (AssemblyWithWebResources_UnitTests.dll.config or App.Config if you recompile) Show quoteHide quote "Frédéric Mayot" wrote: > Hi, > > I'm trying to embed a js file in my class library and register it in an > aspx. > > I created the most simple solution I could : > + ClassLibrary1 : > - Class1.cs > - test.js (embedded resource) > +WebSite > - Default.aspx > > The page is displayed correctly with the resource url : > /WebSite2/WebResource.axd?d=xnJEzCL_Wi5ffEYd13hU2ywYJr-rFccyB13UatbX-2Q1&t=632713812869876368 > > When I copy/paste this link in my browser, I get a blank page.

Extract the contents, open the solution and run it: http://fluidnature.com/test/TestOfWebResources.zip Please, somebody look at this project and tell me what I did wrong embedding these resources and expose them via GetWebResourceUrl?

That
worked for my colleague. Unfortunately it does not seem to work for me, even if I have the exact same code (as far as I know). /david coz wrote: Show quoteHide quote > I have the EXACT problem.

documentation bug and did not charge my incident. My code works when I add the Namespace to both the WebResourceAttribute and the GetWebResourceUrl call. The documentation bug is that all of the examples (on both msdn2 and msdn visual studio 2005) do NOT show the Namespace required anywhere, but in fact it is required (under at least my circumstances!) I believe their examples all exist in the same namespace (both the control with the embedded resource AND the aspx page) so maybe in that case the namespace isnt required... of course, in most circumstances, custom controls cannot be expected to have the same namespace. If this is the case, then the documentation just needs to state clearly that cross-Namespace controls need to include the Namespace.... Here is the documentation that shows examples and no mention of Namespace anywhere: Online: http://msdn2.microsoft.com/en-us/library/bzewcx2t(en-US,VS.80).aspx Visual Studio 2005 help file: ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.en/cpref13/html/T_System_Web_UI_WebResourceAttribute.htm //examples that did NOT work when control : [assembly: WebResource("image1.jpg", "image/jpeg")] [assembly: WebResource("help.htm", "text/html", PerformSubstitution=true)] Show quoteHide quote "Daveli" wrote: > Try moving the WebResource attribute to the AssemblyInfo.cs file.

frustrating and unfruitful diagnostics. Fuul, it appears this also fails if the file extension does not match exactly. Some image programs save jpeg images with JPG file rather than lower case. When I did some testing I noticed that if the case doesn't match between what is specified in the WebResource attribute and the actual file name it doesn't work... You might want to let MS know about this one also. Thanks, Gery *** Sent via Developersdex http://www.developersdex.com *** The default namespace for the website needs to be either empty or added
to the path. So if the default namespace is "ClassLibrary1", then "test.js" should be changed to "ClassLibrary1.test.js" in both for the WebResourceAttribute and in the call to GetWebResourceUrl(). If the file is in a folder (eg: ~/Foo/test.js), then the folder name should be added too ("ClassLibrary1.Foo.test.js"). /david
