---------------------------------
Resolution: Fixed
> Embedded resources fail to load when using VB.Net
> -------------------------------------------------
>
> Key: IBATISNET-85
> URL: https://issues.apache.org/jira/browse/IBATISNET-85
> Project: iBatis for .NET
> Issue Type: Bug
> Reporter: Ron Grabowski
> Assignee: Gilles Bayon
> Priority: Minor

> This line loads the embedded file correclty in C#:
> <providers embedded="Resources.Providers.config, CompanyName.Data" />
> but throws the following exception in VB.Net:
> [NullReferenceException: Object reference not set to an instance of an
> object.]
>
> IBatisNet.Common.Utilities.Resources.GetEmbeddedResourceAsXmlDocument(String
> resource) +129
> The issue is that C# requires the full namespace to the embedded resource be
> used with GetManifestResourceStream while in VB.Net only the file name is
> passed in:
>
> http://www.vbbox.com/blog/2004/05/net-resource-management-stringtable.html
> // C#
> Assembly assembly = Assembly.GetExecutingAssembly();
> Stream s = assembly.GetManifestResourceStream("MyApplication.XMLFile1.xml");
> ' VB.Net
> Dim asm As Assembly = Assembly.GetExecutingAssembly()
> Dim s As Stream = asm.GetManifestResourceStream("XMLFile1.xml")
> Here's some debug output I added to GetEmbeddedResourceAsXmlDocument (if you
> open Resources.cs this will make more sense):
> fileInfo.AssemblyName: [CompanyName.Data]
> fileInfo.ResourceFileName: [CompanyName.Data.Resources.Providers.config]
> assembly.FullName: [CompanyName.Data, Version=0.1.0.0, Culture=neutral,
> PublicKeyToken=null]
> assembly.GetManifestResourceNames().Length: [1]
> assembly.GetManifestResourceNames(): [Providers.config]
> Could not load embedded resource from assembly
> A fix is to replace this line:
> Stream stream =
> assembly.GetManifestResourceStream(fileInfo.ResourceFileName);
> with this:
> Stream stream =
> assembly.GetManifestResourceStream(fileInfo.ResourceFileName);
> if (stream == null)
> {
> stream = assembly.GetManifestResourceStream(fileInfo.FileName);
> }
> There is other code in the GetEmbeddedResourceAsXmlDocument method that calls
> GetManifestResourceStream(fileInfo.FileName) but I think that code is called
> only when the assembly name is not specified by the user. Using this notation:
> <providers embedded="Resources.Providers.config" />
> won't solve the problem because the for loop may load the resource from an
> incorrect assembly.
> With the suggested code change, I think this means that its not possible to
> ship an assembly with embedded resources in this structure and guanrentee
> that the correct resource will be loaded under VB.Net:
> Resources\SqlMaps\SqlServer\User.xml
> Resources\SqlMaps\OleDb\User.xml
> Resources\SqlMaps\Oracle\User.xml
> Perhaps we should caution users who are developing in for deployment in
> another language and recommend they use distinct filenames:
> ???
> Resources\SqlMaps\SqlServer-User.xml
> Resources\SqlMaps\OleDb-User.xml
> Resources\SqlMaps\Oracle-User.xml
> -1 for VB.Net
