what are the Login Dialog Style Flags for aaApi_LoginDlgExt?

the sdk doc for aaApi_LoginDlgExt have a parameter for the LogIn Dialog Style Flags. but when i click on it to take to me the flags it takes me to a blank page in the sdk doc. 

i cant seem to find it in the sdk doc. 

Anyone have any luck finding this??

what im really after is i want to show the login dialog but i want to set the datasource and have it grayed out so the user can not change the datasource. i was hoping this might be one of the flags...has any one done  this? is there a different api call to achieve this?
