Searching Twice gives Object reference null

Question

'Button1
Dim ex1 As New Threading.Thread(AddressOf ex1_sub)
Dim ex2 As New Threading.Thread(AddressOf ex2_sub)
ex1.Start()
ex2.Start()
'End Sub
Sub ex1_sub()
Dim result_ex1 As IWebResult
Dim client_ex1 As New GwebSearchClient("http://www.google.com")
Dim results_ex1 As IList(Of IWebResult) = client_ex1.Search("love", 2)
For Each result_ex1 In results_ex1
MsgBox(result_ex1.Title)
Next
End Sub
Sub ex2_sub()
Dim result_ex2 As IWebResult
Dim client_ex2 As New GwebSearchClient("http://www.google.com")
Dim results_ex2 As IList(Of IWebResult) = client_ex2.Search("hate", 2)
For Each result_ex2 In results_ex2
MsgBox(result_ex2.Title)
Next
End Sub
It points either to results_ex2 or results_ex1 and tells me Object reference not set to an instance of an object.
How could I fix that ?

Hi,
Welcome to MSDN.
As Cor suggested, it needs to wait to get that data.
If any suggestion helpful, you could mark it as answer.
But in addition, issues related to calling api to third-party are not supported, I would suggest you consider connecting with its publisher to get supports.
Thanks for your understanding.
Regards.
