Set a datetime field to current date

Of course you can find it using Google or Bing, but for the sake of it, here is the code you need to use in the form’s OnLoad() event to set the default value to the current date in a datetime field on Microsoft CRM :

var CRMFORMTYPE_CREATE = 1;
var CRMFORMTYPE_UPDATE = 2;
var CRMFORMTYPE_READONLY = 3;
var CRMFORMTYPE_DISABLED = 4;
var CRMFORMTYPE_BULKEDIT = 6;

switch (crmForm.FormType)
{
    case CRMFORMTYPE_CREATE:
        crmForm.all.YOURFIELD.DataValue = new Date();
        break;
    case CRMFORMTYPE_UPDATE:
    case CRMFORMTYPE_READONLY:
    case CRMFORMTYPE_DISABLED:
    case CRMFORMTYPE_BULKEDIT:
        break;
}
