Show how many activities/history associated with a record

Sometimes we want to see how many activities/history associated with a record, it's nice to have a number just like the Outlook Inbox.

Here's the code, it works fine on both CRM 3.0 and 4.0 (slightly different). Please notice that you have to reload the record to get the current number after you add/close an activity.

var buXml = GetRegardingActivity();

if(buXml != null)
{
    var buNodes = buXml.selectNodes("//BusinessEntity/statecode"); // CRM 3.0

    //var buNodes = buXml.selectNodes("//BusinessEntity/q1:statecode"); // CRM 4.0
    var iActivity = 0;
    var iHistory = 0;

    if(buNodes != null )
    {
        /*get values*/
        for( i = 0; i < buNodes.length; i++)
        {
            switch(buNodes[i].text)
            {
                case "Open" : iActivity++; break;
                case "Scheduled" : iActivity++; break;
                case "Completed" : iHistory++; break;
                case "Canceled" : iHistory++; break;
            }
        }

        if(document.getElementById('navActivities') != null)
        {
            document.getElementById('navActivities').getElementsByTagName('NOBR')[0].innerText = document.getElementById('navActivities').getElementsByTagName('NOBR')[0].innerText + " (" + iActivity + ")";
        }

        if(document.getElementById('navActivityHistory') != null)
        {
            document.getElementById('navActivityHistory').getElementsByTagName('NOBR')[0].innerText = document.getElementById('navActivityHistory').getElementsByTagName('NOBR')[0].innerText + " (" + iHistory + ")";
        }
    }
}

CRM 4.0 : get UserId, BusinessUnitId, OrganizationId on client-side JScript (WhoAmIRequest)

I'm sure it's in SDK, but to be clear I made it as a JScript function, so you can easly get UserId, BusinessUnitId and OrganisationId from client-side WhoAmIRequest, it's a good example.

function GetCurrentUserInfo()
{
    var SERVER_URL = "http://CRM";
    var xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
    xmlhttp.open("POST", SERVER_URL + "/mscrmservices/2007/crmservice.asmx", false);
    xmlhttp.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
    xmlhttp.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/crm/2007/WebServices/Execute");
    
    var soapBody = "<soap:Body>"+
    "<Execute xmlns='http://schemas.microsoft.com/crm/2007/WebServices'>"+
    "<Request xsi:type='WhoAmIRequest' />"+
    "</Execute></soap:Body>";
    
    var soapXml = "<soap:Envelope " +
    "xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' "+
    "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' "+
    "xmlns:xsd='http://www.w3.org/2001/XMLSchema'>";

    soapXml += GenerateAuthenticationHeader();
    soapXml += soapBody;
    soapXml += "</soap:Envelope>";

    xmlhttp.send(soapXml);
    xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async=false;
    xmlDoc.loadXML(xmlhttp.responseXML.xml);
    
    var userid = xmlDoc.getElementsByTagName("UserId")[0].childNodes[0].nodeValue;
    var buid = xmlDoc.getElementsByTagName("BusinessUnitId")[0].childNodes[0].nodeValue;
    var orgid = xmlDoc.getElementsByTagName("OrganizationId")[0].childNodes[0].nodeValue;

    alert("UserId: " + userid + "\r\nBusinessUnitId: " + buid + "\r\nOrganizationId: " + orgid);

CRM 4.0 : Check current user's security role using JavaScript

It's a common question about how to show/hide fields based on user's security roles.
Ronald Lemmen had a very popular post on his blog about how to use 'RemoteCommand' to achieve that in CRM 3.0. Because 'RemoteCommand' is for internal use and unsupported, it doesn't work in CRM 4.0.
Michael H?hne also had a great post about how to access web service using client-side JavaScript. Since CRM 4.0 web service EndPoint changed, some people get 401 authorization error.

Here's code which works great in CRM 4.0, the function UserHasRole("ROLE_NAME") returns true if the current has the role, returns false if it doesn't. GetCurrentUserRoles() function generated by Michael H?hne's tool with some changes. Thanks for Regan who point out that using GenerateAuthenticationHeader() instead of hard-coding the Organization's Name.

//check if the current user has the 'System Administrator' role
alert(UserHasRole("System Administrator"));

function UserHasRole(roleName)
{
 //get Current User Roles, oXml is an object
 var oXml = GetCurrentUserRoles();
 if(oXml != null)
 {
  //select the node text
  var roles = oXml.selectNodes("//BusinessEntity/q1:name");
  if(roles != null)
  {
   for( i = 0; i < roles.length; i++)
   {
    if(roles[i].text == roleName)
    {
     //return true if user has this role
     return true;
    }
   }
  }
 }
 //otherwise return false
 return false;
}

Due to Bloger's format issue, I have rewrite the code, it should work for everyone now.:)
