Hi,
I'm using QueryByAttribute and I need to check that the attribute "id" is not null.
allcontacts.Attributes = new string[] { "id" };
allcontacts.Values = new object[] { XXXX };
I need to replace XXXX with an expression to indicate Not Null value.
Can you please help me with that ?
Thanks
M
EDIT:
I'm doing this because i need to retrieve all the contacts i have in my crm using QueryByAttribute, without adding an attribute, I'm receiving an error that the query attribute array cannot be empty. So I'm adding a dummy attribute just to have an attribute
check.
