Today I received a mail from the developer that the program occasionally reports an error when calling a function, but most of the time it is normal, the specific error is as follows:
12/8/2010 5:54:34 PM – Checking MERGED DFMS with Servicetag [128QPN1]
12/8/2010 5:54:34 PM – Creating Dataset

12/8/2010 5:54:34 PM – Exception Caught:System.NullReferenceException: Object reference not set to an instance of an object.
at TEST_DFMS.Form1.button4_Click(Object sender, EventArgs e)

ORA-24338 statement handle not executed

Cursor not executed
