Enterprise Library
26 de Outubro de 2012 – 8:32
The Microsoft Enterprise Library is a collection of reusable software components (application blocks) designed to assist software developers with common enterprise development cross-cutting concerns (such as logging, validation, data access, exception handling, and many others). Application blocks are a type of guidance; they are provided as source code, test cases, and documentation that can be used “as is,” extended, or modified by developers to use on complex, enterprise-level line-of-business development projects.
ASP.NET 4.0 potentially dangerous Request.Form value was detected
6 de Julho de 2012 – 14:39
This was because .NET detected something in the entered text which looked like an HTML statement.
This is a feature put in place to protect your application cross site scripting attack and followed accordingly.
To disable request validation, I added the following to the existing “page” directive in that .aspx file.
ValidateRequest="false"
For .NET 4, we need to add requestValidationMode=”2.0″ to the httpRuntime configuration section of the web.config file like the following:
<httpRuntime requestValidationMode="2.0"/>
But if there is no httpRuntime section in the web.config file, then this goes inside the <system.web> section.
If anyone wants to turn off request validation for globally user, the following line in the web.config file within <system.web> section:
<pages validateRequest="false" />

TreeView.SelectedNodeChanged Event, doesn’t fire
8 de Março de 2012 – 12:42
Occurs when a node is selected in the TreeView control.
If we assign any URLs to the NavigateUrl propery of the TreeNode, it will render as a <a> tag, it will not do postback, so it will not file the event;
If we do not assign any URLs to the NavigateUrl propery of the TreeNode, it will render as a short JavaScript which used to postback.
So I think maybe you have assign URLs to the NavigateUrl propery of the TreeNode.

vbc : warning BC40010
10 de Fevereiro de 2011 – 22:34
error message:
I get this message when building my Assembly :

vbc : warning BC40010: Possible problem detected while building assembly ‘asdasd’: Referenced assembly ‘asdasd’ is a localized satellite assembly
Building satellite assemblies…

————————————————————————————–
The assembly you are building is localized differently than the assembly that are referencing.
This probably means that somewhere in the source code for “asdasd” you have an AssemblyCultureAttribute that is present. Code assemblies should never have this attribute — if you remove it, the problem should go away.
