)

VB.NET

Remarks

You can pass nothing as the method’s parameter to create a rule that allows access to all file directories:

// Image load from file directories is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow()); 

VB.NET

' Image load from file directories is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow()) 

Pass the file directories that should be accessible in the application to allow resource loading only from them:

C#

// Image load is allowed only from the specified file directories.
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow("http://mysite.dev"));

VB.NET

' Image load is allowed only from the specified file directories.
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow("http://mysite.dev"))
