/warnaserror[+ | -]
Any messages that would ordinarily be reported as warnings are instead reported as errors, and the build process is halted (no output files are built).
By default, /warnaserror- is in effect, which causes warnings to not prevent the generation of an output file. /warnaserror, which is the same as /warnaserror+, causes warnings to be treated as errors.
Use /warn to specify the level of warnings that you want the compiler to display.
Note The /warnaserror option has not yet been implemented in the Visual Basic command line compiler.
Compile in.vb
and have the compiler display no warnings:
vbc /warnaserror in.vb
