• Re: CustomErrors redirect not working as needed when a non aspx resource is in the url

  I'm having the same problem as the original poster ... Very aggravating and it renders the concept of a custom 404 page rather useless.

• Bizarre problem with ASP.Net (2.0) form

  I have an ASP.Net form that had been working fine for months. Suddenly, on postback, I am presented with a blank (white) page with the following: 1360|/wEWpwEC1tSUhwICl/mS5AEC57O39AYCx9uNWwLFgulXAsDWrp0DAueJuc0OAt6m9vIJAou+3LgJAsi2q80MAtmp+tQOApv6nIICAs/noqgBAs/zrHwCzarE5wIC0+H89wIC547OBgLr5JP0CwKKj6OLDgKrkd+dAwKM45DPCgLwje2zBQKBifXDCQLxhf27DgLSnsXoCQLymIKsDAK2qNT1BQKhzb+BBgKijoWzBwK595ZSAqef32oCuN63tAUC/uGa5QcC0cWP1gcCr7zIuAMCxvvBUwKcw/HfBQLh/duOAwK2wpDKAwLGiMfIBQKP9cmbDQK+46jiBwKNuLiTCgKBtY/KCwLtgs2qBAKes8bFDQKes

• Vexing problem with HttpHandlers in 2.0

  Hi! My app has a custom handler (IHttpHandler) for handling requests for certain file types and a custom handler factory(IHttpHandlerFactory) for rewriting URLs of .aspx files. The file handler has been working fine. The url handler works great. They seem to be fine together: in debug mode. Sadly, when I pull up the app via its url -- http://server/app/start.aspx -- everything works great EXCEPT several javascript files -- which are supposed to handled by the file handler -- are not, and when I look

• Problem precompiling a Web App

  Hey there ... I'm trying to precompile my app, but when I run "Publish Web Site" I'm getting hundreds of errors referring to "circular references" ... which I cannot seem to find when clicking on the error message and navigating to the alleged offending line of code. The site builds -- "Build Web Site" -- with no errors. I have "batch" set to true in web.config (see below). < compilation debug = " true " batch = "true " > Any ideas? Thanks! Buzzcut

• Re: Getting "The Type must be loadable by BuildManager.GetType(string typeName)" though the dll is in bin

  More info: If I explicitly create the object rather than using Reflection -- WebPart p = new MyAssembly.WebPart1(); The WebPartManager is able to load it. This is unhelpful, however, as the Type i want to load won't be available till runtime.

• Getting "The Type must be loadable by BuildManager.GetType(string typeName)" though the dll is in bin

  I have a .dll, SampleWebParts, in the bin directory. It contains two types that inherit WebPart -- WebPart1 and WebPart2 Here's a snippet: Assembly asm = Assembly .LoadFile(path); //load dll from bin Type t = asm.GetType("WebPart1"); object o = Activator .CreateInstance(t); WebPart p = ( WebPart )o; //At this point p is a WebPart1 object WPM.AddWebPart(p, zone, 0); //Add it to WebPartManager Then I get the nefarious exception: System.InvalidOperationException was unhandled by user code Message="Cannot

• Problem exporting WebParts in class library

  I'm trying to create a component that scans a .dll for classes that descend from WebPart and use WebPartManager.ExportWebPart to write the .WebPart files to a company specific directory, where my ImportCatalog part can, well, import them. public void ExportWebParts( ArrayList parts) //an ArrayList of WebParts { string strFile = "" ; WebPartManager mgr = new WebPartManager (); foreach ( Type t in parts) { strFile = t.Name + ".WebPart" ; strFile = WebPartPath + '\\' + strFile; object o = Activator

• Setting a "default" personalization state

  I'd like to enable an Admin to create a "default" Personalization state that will be loaded for a User the first time he accesses the application. After that he'd (User) obviously be able to configure his own pages. I see where there is a "DefaultProfile" and have run across the class SharedPersonalizationStateInfo , but there is not much documentation on how to use these. Thanks!
