Dim table As List
table.Initialize
For i = 1 To 100
 table.Add(Array(1, 2))
Next
Dim row() As Object = table.Get(7)

and i have another , it is

i use such sentence to query access database in vb ,

it is ,

SELECT *
FROM table_1
WHERE (

((IIf(IsNull(value_1),'*' , field_1 Like '*' & value_1 & '*'))<>False) AND

'((IIf(IsNull(value_2),'*', field_2 Like '*' & value_2 & '*'))<>False) )

i imitate it in b4a , i make attempts time and again , but the matter(problem) is " IIf(IsNull(value_1) " ,

always failed in " IIf(IsNull(value_1) " ,

i wonder how to do to to achieve such function in b4a ,

and , it seems that we can not use IsNull() ,Isempty() , to judge empty and null ,

and i see blank when i put mouse on value_3 ,

sentence is that value_3 = EditText_1.text , when EditText_1 is blank ,

at the outset i think it(black) mean empty or null ,

afterwards i discover it mean "" ,

so i can use [ if value_3 = "" then ] ,

i mean , there iare puzzle in empty , "" , null , and in remind display ,
