Configuration – simple on class and attribute level

It is possible to declare your validation rules in various ways. It is suggested primarily to try it on class and attribute level and secondary using dependency-callback.

Example class and attribute rules:

class=”required email” minlength=”2″ title=”Required or not correct format.” />

/* this would check that email is entered, that at least 2 characters are typed and also that email validation rule */

The validation on the form is registered by

A list of available validators can be found here http://docs.jquery.com/Plugins/Validation/#List_of_built-in_Validation_methods

There are also custom validation rules that can be implemented by including additional-methods.js (when you download the plugin validation package).

If you don’t specify any validation messages you will get standard validation messages so it would be a nice thing to specify your own. The title attribute is available for a standard message, however if you need to customize the message for each different type of validation error, check later advanced topic on how to customization validate()

Configuration – custom messages

To specify your own messages you pass it into your form validation rules

The validation on the form is changed to

Configuration – specify rules for validate()

It is possible to define your own rules by sending on more options for validate()

Example class and attribute rules:

/* notice that we now removed the class and attribute rules from the input element */

The validation on the form is then changed to use

Configuration – validation using dependency expression

It is possible to define limit validation for a specific expression (such as #object:checked, #object:filled, #object.visible)

The validation on the form is then changed to use

Configuration – validation using dependency callback

It is possible to define limit validation using your own functions. This enables even more complex checks such as ajax-calls to perform server side checks.

The validation on the form is then changed to use

It is also possible to use the addMethod() to register any custom checks to the validator

Placement of errors

By default jQuery validator injects the error messages just next to the control that does not validate. It also adds an error class on each element that does not validate. Therefore it is easy to style elements and give an invalid element a red border when it is invalid.

input.error { border: 1px solid red; }

input.error:focus { border: 1px solid red; }

style>

If you want to override the placement of errors next to your invalid control you can specify the errorPlacement function.

December 27, 2009 – January 13, 2010 I was on a fantastic trip to South Africa, Mocambique and Swaziland. A total of 3000 km was spent driving to the different destinations (you should see them pinned in one of the images that represents the map). The wildlife is amazing and the people are superfriendly. I’d like to share some of my images from this trip and hope you will enjoy them. Definately a trip worth remembering.

The only setback was that the diving in Mocambique was somewhat disappointing considering the other spots I have visited. On the other hand there are not many other dive sites that have the same opportunities to enjoy Whale Sharks and Manta Rays.

Some friends (Rita and Rene) arranged a diving trip to Sharm El Sheikh in Egypt for a week in November 2008. We had a lovely time diving at some various spots including Ras Mohammad national park and Dahab.

Diving in Maldives, Kuredu

In April 2008 we made a diving trip to Maldives and the island Kuredu. Kuredu is in the Lhaviyani Atoll a bit north of Male airport. The diving was quite nice although I heard from Christian that there are much more life in other more southern atolls (probably due to overfishing where the islands are more populated). Although you don’t have to dive to get some nice views (we saw the most just by snorkling on the outter rief). This was also the first time I got to see a Manta Ray. If you wish to travel there you can book a stay at http://www.kuredu.com

Avoiding local maildrop when using CDOSYS

Hans Rasmussen — Fri, 19 Feb 2010 23:48:10 +0000

I experienced strange problems with some ASP scripts at a clients hosted web server. The script sends e-mails after completed execution and occasionally (quite often) some of the e-mails are not delivered or are delivered much later than expected. When running in a hosted environment it is also very hard to track as you have very limited access to the server itself. After digging in some Microsoft documentation I noticed that it is possible to direct the traffic to the SMTP server of your choice instead. CDOSYS will execute a little bit slower but now I have the opportunity to target the e-mail to the SMTP server of my choice.

Set oCdoMail = Server.CreateObject(“CDO.Message”)

Set oCdoConf = Server.CreateObject(“CDO.Configuration”)

sConfURL = “http://schemas.microsoft.com/cdo/configuration/”

with oCdoConf

.Fields.Item(sConfURL & “sendusing”) = 2

.Fields.Item(sConfURL & “smtpserver”) = “smtp.themailserverofyourchoice.com”

.Fields.Item(sConfURL & “smtpserverport”) = 25

.Fields.Item(sConfURL & “smtpauthenticate”) = 1

.Fields.Item(sConfURL & “sendusername”) = “accountname@themailserverofyourchoice.com“

.Fields.Item(sConfURL & “sendpassword”) = “verysecretpassword”

.Fields.Update

end with

oCdoMail.From = ”fromemail@someserver.com”

oCdoMail.To = ”toemail@someserver.com”

oCdoMail.Subject = ”Subjct of the message”

oCdoMail.HTMLBody = “Some message including some HTML coding”

oCdoMail.Configuration = oCdoConf

oCdoMail.Send

Set oCdoConf = Nothing

Set oCdoMail = Nothing

CRM Authentication

Hans Rasmussen — Fri, 19 Feb 2010 23:47:49 +0000

One good way of Authenticating against CRM Webservice is not tell CRM which internally defined system user account you wish to authenticate against. I found this good article from Microsoft about how to lookup the system user account based on the GUID that it receives in CRM after you have told CRM that you wish to create a user for this account.

http://msdn.microsoft.com/en-us/library/cc151052.aspx

//extract from the link above

using System;

using System.Web.Services.Protocols;

using System.Text;

using System.Net;

using System.Xml;

namespace Microsoft.Crm.Sdk.Reference

{

// Microsoft Dynamics CRM namespaces

using CrmSdk;

using

CrmSdk.Discovery;

public class Impersonation

{

[STAThread]public static void Main(string[] args)

{

CrmAuthenticationToken token = new CrmAuthenticationToken

();

token.AuthenticationType = 0; // Use Active Directory authentication.

token.OrganizationName = “AdventureWorksCycle”;

// Use the global user ID of the system user that is to be impersonated.

token.CallerId = new Guid(“94092D6F-B367-DC11-9C93-0003FFDFCE28″);

CrmService crmService = new CrmService();crmService.Url =

“http://localhost/MSCRMServices/2007/CrmService.asmx”;

crmService.CrmAuthenticationTokenValue = token;

crmService.Credentials = System.Net.CredentialCache.DefaultCredentials;

// Create a new account owned by the impersonated user.

account account = new account();

account.name = “Fabrikam”;

Guid accountid = crmService.Create(account);

}

// my own code comes here

The other way is of course to authenticate youself by providing this information to CRM Web service.

CrmService service = null;

service = new CrmService();

service.Url = “http://crm/MSCrmServices/2007/CrmService.asmx”;

CrmAuthenticationToken token = new CrmAuthenticationToken();

token.AuthenticationType = 0;

token.OrganizationName = “putyourorganizationnamehere”;

System.Net.ICredentials myCredentials;myCredentials =

new NetworkCredential(“useraccount”, “password****”, “domain”);

service.Credentials = myCredentials;

service.PreAuthenticate = true;

service.CrmAuthenticationTokenValue = token;

// do your stuff on service object (same as the above example)

// Create a new account owned by the impersonated user.

account account = new account();

account.name = “Fabrikam”;

Guid accountid = crmService.Create(account);

Encoding in your Visual Studio project

Hans Rasmussen — Fri, 19 Feb 2010 23:47:26 +0000

Have you experienced problems in your Visual Studio projects that no matter which encoding you try to use in your pages for XML or but still you have problems solving swedish characters such as å, å and ö when posting information to external webservice etc.

Try and configure your application’s web.config file and add encoding to your globalization element and now things are working way better.

fileEncoding=”iso-8859-1″

requestEncoding=”iso-8859-1″

responseEncoding=”iso-8859-1″

This behavior to determine encoding is probably the reason why a WebForm intitially contains no information about encoding at all.
