Parameters

errorCode: Type: System Int32
The code which identifies the error.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	Thrown if the errorCode is less than or equal to 0 or greater than 4095 (0xFFF).

Remarks

The NDM supports 16 bits of error code information.

Currently the NDM does _not_ define its own error codes. You must supply your own meaningful error codes as arguments to NotifyError(Int32). Cognex recommends using the lower 12-bits (0x0001 to 0x0FFF) for your error codes.
