How to: Enable or Disable Compiler Warnings (Visual Basic)
The Visual Basic compiler can detect potential problems in your code and issue warnings so that you can review them. By default, all compiler warnings are added to the Task List during compilation. You can change the behavior of the compiler so that it does not issue warnings, or so that it will treat warnings as compilation errors that must be fixed immediately.
Compiler warnings can be enabled or disabled in the Compile page of the Project Designer.
Note
Enabling or disabling certain compiler warnings may also change the value of the Option Strict property. For more information, see How to: Set Compiler Options (Visual Basic).
