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:

&lt;pages validateRequest=&quot;false&quot; /&gt;

What is a PAD file?

29 de Junho de 2012 – 14:48

PAD stands for Portable Application Description, and a PAD file is a clear and easy way for software authors to provide online sources with information about their products. The advantage of using a PAD file is that it enables you to store all the descriptions and specifications in one single place – system requirements, price, contact info, file names, download URL’s and more.

Another great thing about PAD files is that they’re so easy to create – and that it doesn’t cost you anything! The Association of Shareware Professionals have put together a range of totally free tools that allow you to create and modify your PAD files. Here at SoftwarePromotions, we have also created our own PAD file tools to make life easier for software authors – check out our guide to using PADGen and our PAD validation tool.

Once you have created your PAD file, you should put it in two different places. First in your ZIP file, so that the people who distribute your software can access all the information that they might need. Second, you also want to put your PAD file on your own website, since this is what many of the download sites will ask you for.

Since June 2001, SoftwarePromotions has been working exclusively with PAD files. This is because the PAD format allows us to get your software listed on as many sites as possible, in the shortest amount of time.

MySQL

MySQL, CREATE FUNCTION Syntax

25 de Maio de 2012 – 13:52

The general syntax of Creating a Function is :

 CREATE FUNCTION func_name ([func_parameter[,...]]) RETURNS type routine_body

func_name : Function name
func_parameter : param_name type
type : Any valid MySQL datatype
routine_body : Valid SQL procedure statement

 The RETURN clause is mandatory for FUNCTION . It used to indicate the return type of function.

Now we are describing you a simple example a function. This function take a parameter and it is used to perform an operation by using an SQL function and return the result. In this example there is no need to use delimiter because it contains no internal ; statement delimiters. Example :

CREATE FUNCTION func(str CHAR(20))
RETURNS CHAR(50)
RETURN CONCAT('WELCOME TO, ',str,'!');

Query OK, 0 rows affected (0.00 sec)

 SELECT func('Galhano.com');

 

+------------------------+
| func('Galhano.com')      |
+------------------------+
| WELCOME TO, Galhano.com |
+------------------------+
1 row in set (0.00 sec)

Project page at codeplex: http://highcharts.codeplex.com

You can see some Highcharts.Net examples at this link: http://highcharts.paulovich.com.br/

After download the newest release, add it as reference on your web application, and then add it to the page controls on your web.config:

Exchange Microsoft

Manually update and rebuild the Exchange 2003 GAL

20 de Abril de 2012 – 11:31

This how-to walks through the process of manually updating offline address books for users from Exchange 2003 as well as the Global Address List.

  1. Open Exchange System Manager
    This how-to was actually made on a WS2003STD SP2.
  2. Expand Recipients and Select “Offline Address Lists”
  3. In the right pane, right click the “Default Offline Address List” and select “Rebuild”
  4. It will give you a prompt about how long it can take
    Just click “Yes”
  5. Repeat this for the “Global Address List”
    In the left pane, now click on “Recipient Update Services”
  6. In the right pane, right click on each choice, first selecting “Update Now” on both, and then again selecting “Rebuild” on both
  7. That’s all

This can take several hours though, with my 100 users it generally takes about 40 minutes max.

I would also submit that you can manually re-download the address books via Outlook by selecting the small arrow next to send/receive and then clicking on (you guessed right!) “Download Address Book”.
