Expression Blend Linked Resources Error "Unable to find the specified file"

2009-09-24T15:59:00Z

If you ever receive an "Unable to find the specified file" error in Expression Blend while trying to call a Linked Resource File ( like in a shared assembly where you want to save your shared resources ), called in your app.xaml like this one:

<Application.Resources>
      <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/YourAssembly;Component/Resources/YourResources.xaml"/>
        </ResourceDictionary.MergedDictionaries>
      </ResourceDictionary>
    </Application.Resources>

Be sure that "YourAssembly" is from a project of type "WPF Custom Control Library" and NOT just a "Class Library".

Hope this helps,

Immediate Interfaces for a type

2009-03-31T18:41:00Z

If anybody is interested to get the immediate interfaces for a type, this a way to get it:

          /// <summary>
          /// Gets the immediate interfaces.
          /// </summary>
          /// <param name="type">The type.</param>
          /// <returns></returns>
          public static Type[] GetImmediateInterfaces(Type type)
          {
              Type[] interfaces = type.GetInterfaces();
              return GetImmediateInterfaces(interfaces);
          }
  
          /// <summary>
          /// Gets the immediate interfaces.
          /// </summary>
          /// <param name="interfaces">The interfaces.</param>
          /// <returns></returns>
          public static Type[] GetImmediateInterfaces(Type[] interfaces)
          {
              List<Type> immediateInterfaces = new List<Type>();
  
              foreach (Type possibleImmediateInterface in interfaces)
              {
                  bool isBaseInterface = false;
  
                  foreach (Type baseInterface in interfaces)
                  {
                      if (possibleImmediateInterface != baseInterface && possibleImmediateInterface.IsAssignableFrom(baseInterface))
                      {
                          isBaseInterface = true;
                          break;
                      }
                  }
  
                  if (!isBaseInterface)
                      immediateInterfaces.Add(possibleImmediateInterface);
              }
  
              return immediateInterfaces.ToArray();
          }

Silverlight Error #2104 Could not download the silverlight application in IIS6

2008-06-14T19:43:00Z

If you receive this error while trying to deploy your Silverlight application, make sure you did the following things:

1. Adjust the Content Expiration Setting

You should adjust the content expiration setting to 1 minute. The following procedure outlines how to do this with IIS.

Right-click your Web Site and select Properties from the context menu.
Select the HTTP Headers tab and click "Enable Content Expiration".
Set the content to expire after 1 minute.

2. Register MIME Types and File Extensions

You must register some MIME types and file extensions so that the browser on the client's system can load the correct handler. You need to add the following types:

Extension	MIME Type
.xap	application/octet-stream
.xaml	application/xaml+xml

The .xap needs to have that mime type, in order to be able to be downloaded.

3. Execute permissions must be Scripts Only.

Right-click your Web Site and select Properties from the context menu.
Select the Directory tab and change "Execute Permissions" to Script only.

Hope this helps.

SSAS Calculations Tab - Unexpected error ocurred: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'

2008-02-06T22:56:00Z

This error is caused because an installation of the Office 2007 overwrites two particular files that are used by SSAS 2005:

- msmdlocal.dll

- msmgdsrv.dll

Unexpected error ocurred: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'

So the solution is to copy this two files from:

%programfiles%\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\

to:

%programfiles%\Common Files\System\Ole DB\

ReportServicesConfigUI.WMIProvider.WMIProviderException: The report server installation is not initialized.

2008-01-31T05:29:00Z

If you are getting this error "ReportServicesConfigUI.WMIProvider.WMIProviderException: The report server installation is not initialized."

Means that for some reason ( usually because of an upgrade, or a change of the physical location of the reporting services folders ) the report server was deactivated.

To initalize it, go to Start-> All Programs -> SQL Server 2005 -> Configuration Tools -> Reporting Services Configuration

And then, go to the Initialization tab. Remove all the items there and then press initialize, reporting services will insert a new one that is working good by default.

Failed to load expression host assembly. Details: Could not load file or assembly ...

2008-01-31T05:24:00Z

In Reporting Services, if you are getting this error is because you need to copy your referenced assemblies of the report into the folder

Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\bin

If you are in the designer you need to copy it into this one too

Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies

The type 'System.Web.UI.ScriptManager' is ambiguous: it could come from assembly...

2008-01-31T03:58:00Z

If you are trying to migrate an old application to work with the framework 3.5, you are using ajax, and get the following error...

The type 'System.Web.UI.ScriptManager' is ambiguous: it could come from assembly 'C:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions\1.0.61025.0__31bf3856ad364e35\System.Web.Extensions.dll' or from assembly 'C:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll'. Please specify the assembly explicitly in the type name.

You need to delete all your \bin files and rebuild the application.

Visual Studio not showing the toolbox items properly

2008-01-15T05:26:00Z

If you have any trouble using the toolbox items in visual studio, just delete the hidden files:

toolbox.tbd, toolbox_reset.tbd, toolboxIndex.tbd, toolboxIndex_reset.tbd

<drive>:\Documents and Settings\<user>\Local Settings\Application Data\Microsoft\VisualStudio\<VS version>

Ex:

C:\Documents and Settings\JAVIER.VILLARREAL\Local Settings\Application Data\Microsoft\VisualStudio\8.0

Start Visual Studio, and it will reset the toolbox items in the correct form.
