The component 'XYZ does not have a resource identified by the URI...

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :JQuery

Hi All,

A while ago I wrote an application which used plug-ins. It was based on WinForms but I recently reworked it to use WPF. One of the features it has is the ability to drop plugins into the folder and have them startup (and starts any dependencies if they're not started).

Now, If I have the plugins already in the directory when I startup the main application everything runs okay.

If I load the main application without a plugin and then add the plugin sometime later I receive the following error: "The component 'XYZ' does not have a resource identified by the URI '/ThePluginAssembly;component/MyUsercontrol.xaml'" on the InitializeComponent() method in the UserControls constructor.

The key points are:

1. The user control is located in the plugin assembly

2. I am trying to create the usercontrol from inside the plugin assembly

3. The plugins are located in the same directory as the main application

4. The user controls only have problems when they are created through XAML. I have a couple of other usercontrols in the same assembly but I instantiate these using code. I only receive the error message when I attempt to create a UserControl in XAML.

5. I have read

The component does not have a resource identified by the URI - problem


I know this has been asked before, but I haven't found any solution to it.

I have an assembly with multiple CustomControls defined in it.

Now when I added a UserControl to the assembly I get this error on launching the control.

I have made sure there is no duplicated dlls ofthe same assembly, there are only 2 copies, the assembly obj\debug output folder and the apps bin\debug folder.

Any suggestions?

set messageTemplateResourceName from resource file in Validation appication block.



  I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.

Here is my code:

<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250"
              upperBoundType="Inclusive" negated="false" messageTemplate=""
              messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=, Culture=neutral, PublicKeyToken=null"
              tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris

I am experimenting with using EnterpriseServices. I created a component, created the SNK file, compiled the DLL. In the assemblyinfo.vb file, I added '<Assembly: AssemblyKeyFile("c:\key.snk")> '.
I created a new package in COM+, When I attempt to add the .dll to the package i get:

Error Code 80020009 - Exception ocurred.
