Exception message “entityName” in CRM 2011

Hi,

We get the “entityName” exception if we haven’t specified value for LogicalName property of Entity class. (easy to figure out )
Hope it helps!

Calling Asp.NET web service from form onLoad in CRM

This is the code we can make use for calling ASP.NET webservice in form onLoad javascript event handler of our Entity in Microsoft CRM.

This example calls the simple Hello World service and assigns the value returned (i.e. “Hello World”) to a field in the entity form

xmlHttp=new ActiveXObject(“Microsoft.XMLHTTP”);

xmlHttp.open(‘post’, ‘http://localhost/WebService1/Service1.asmx/HelloWorld’, false);

xmlHttp.send();

var xmlDoc=xmlHttp.responseXML;

var responseElement=xmlDoc.getElementsByTagName(“string”)[0];

var exch=responseElement.firstChild.nodeValue;

crmForm.all.address1_name.DataValue=exch ;

return false;
