Reads the value of a register in the registry of the Mobile Device (Pocket PC) connected to the current computer.
Note: To handle the registry of the Mobile Device, a connection must be established between the current computer and the Mobile Device (ceConnect).
Example
// Reads the "Language" value in the "HKEY_LOCAL_MACHINE\SOFTWARE\MyApp" key
// ResExecute is a boolean used to find out whether the value was read
ResRead = ceRegistryQueryValue("HKEY_LOCAL_MACHINE\SOFTWARE\MyApp", "Language", ResExecute)

IF ResExecute = True THEN
Info("The value was read and it is set to: " + ResRead)
END

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

The operating mode of ceRegistryQueryValue is equivalent to the operating mode of RegistryQueryValue.
The only difference is:
  • ceRegistryQueryValue handles the registry of the Mobile Device from a WINDEV application.
  • RegistryQueryValue 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.
