Hi,

I beleive that I have answered this by email, but incase you did not recieve the email here is the solution.

In the visual basic example the .bas file declaration for the ps3000_set_trigger is incorrect. The last parameter (auto_trigger_ms) is being passed by reference where infact it should be passed by value. This means that the new declaration should look like this:

Code:
 Declare Function ps3000_set_trigger Lib "\ps3000.dll" (ByVal handle As Integer, ByVal source As Integer, ByVal threshold As Integer, ByVal direction As Integer, ByVal delay As Integer, ByVal auto_trigger_ms As Integer) As Integer


Best regards,
