Term

Definition

numberList

Optional. Comma-delimited list of the warning ID numbers that the compiler should suppress. If the warning IDs are not specified, all warnings are suppressed.

The /nowarn option causes the compiler to not generate warnings. To suppress an individual warning, supply the warning ID to the /nowarn option following the colon. Separate multiple warning numbers with commas.

You need to specify only the numeric part of the warning identifier. For example, if you want to suppress BC42024, the warning for unused local variables, specify /nowarn:42024.

For more information on the warning ID numbers, see Configuring Warnings in Visual Basic.
