ResExist = ceRegistryExist("HKEY_LOCAL_MACHINE\SOFTWARE\MyApp")

Remarks

Registry of the Mobile Device

The following branches do not exist on a Mobile Device:
  • HKEY_PERFORMANCE_DATA,
  • HKEY_CURRENT_CONFIG,
  • HKEY_DYN_DATA.

Equivalence

ceRegistryExist and RegistryExist have equivalent operating modes.
The only difference is:
  • ceRegistryExist handles the registry of the Mobile Device from a WINDEV application.
  • RegistryExist handles the registry of the Mobile Device only from a WINDEV Mobile application.

Registry of a Smartphone

The access to the registry may fail on some Smartphones. In this case, the ErrorOccurred variable is set to True.
