Hi, I need to write a trigger by which whenever a Contact is created, an email must be sent to the mail-id we specify. In that mail there should be :
Contact Details : 1.First Name. 2.LastName, 3.Account , 4.Content Like : "Hi , an Acc. is created bla bla bla......" 

Hi,
I have a requirement where i need to get the total count of Logins done by the particular profile.

Profile                                      Month                       Times Logged in
System Administrator                August 2016              150
Standard User                          August 2016               123


I tried to give this query,
List<Aggregateresult> logquery = [Select count(LoginTime) logintime, userid from LoginHistory where userid =: scope Group by userid];

But this wil execute the total count by Users. But i need it for Profiles. Is there any other workaround to do this?

Thanks
Vivekh
 

Good afternoon,
I am hoping you can help me.
I am building a POC and i have hit a brick wall and really appreciate some help form the community.

Problems :
My visual force page doesnt show a tick box. When i push save, i dont see the record being mapped back anywhere. when on Materials_Junction object and look at Buttons, Links, and Actions i edit the "new" button to add the visual force page, however no vf pages are presented.

Ideal Solution :
Go to the sales & marketing object, scroll to the "Materials_Junction" related list and click on "New". Upon clicking on "New" it should open up the "visual force" page below (which references the "materials" object). The user should select the "material" via a tick box add a quantity,upon clicking the save button on the visual force page, the values the user has selected should get mapped back to the "sales & marketing object"
