I tried this code for a command line app, and it did not work.
I did not crash, itjust did not write antthing visibly.
What am i doing wrong?
I was using VB6.
I want to write an exe which when called in a cmd window without
command line parameters writes a short information message in the
cmd window it is runnning in.
