# This example shows how to handle silent installers.
# In short, you need IfSilent and the /SD switch for MessageBox to make your installer
# really silent when the /S switch is used.
Name "Silent"
OutFile "silent.exe"
RequestExecutionLevel user
# uncomment the following line to make the installer silent by default.
; SilentInstall silent
Function .onInit
# `/SD IDYES' tells MessageBox to automatically choose IDYES if the installer is silent
# in this case, the installer can only be silent if the user used the /S switch or if
# you've uncommented line number 5
MessageBox MB_YESNO|MB_ICONQUESTION "Would you like the installer to be silent from now on?" \
/SD IDYES IDNO no IDYES yes
# SetSilent can only be used in .onInit and doesn't work well along with `SetSilent silent'
yes:
SetSilent silent
Goto done
no:
SetSilent normal

# when `SetOverwrite on' (which is the default) is used, the installer will show a message
# if it can't open a file for writing. On silent installers, the ignore option will be
# automatically selected. if `AllowSkipFiles off' (default is on) was used, there is no
# ignore option and the cancel option will be automatically selected.
