Possible bug in FindCoordTransformUsingRect

[satriani81]

Hi all,
using the latest Ni development module under VB .NET, I noted a strange behaviour in FindCoordTransformUsingRect returned values after an exception condition.
I put this function in a Try.. Cach block so, if there is a blank image (missing part), the software doesn't crash. After a missing part condition, FindCoordTransformUsingRect is able to set a reference/measurement system, but it returns always the error code 31842. Why this ? How can I know, after an exception, if the FindCoordTransformUsingRect is doing the right job?

Thanks in advance

PS
the missing part condition is not the only exception cause, I can't prevent the exception, I can only manage it.

Hello satriani,

are you using IMAQ Vision 8.5 therefore?
