Clearing a Field

A field can be cleared, and its null field flag set, by calling CTRecord.ClearField() method. Call CTRecord.IsNullField() to check if a field null flag is set.

// if a field 0 is not null, clear the field

if (!ARecord.IsNullField(0))

{

try

{

ARecord.ClearField(0);

}

catch (CTException err)

{

Console.Write("Clear field failed with error {0}\n", err.GetErrorCode());

}

}
