ceRegistryQueryValue (Function) In french: ceRegistreLit Reads the value of a register from the registry of the Mobile Terminal (Pocket PC) connected to the current station. Remark: To handle the registry of the Mobile Device, a connection must be established between the current computer and the Mobile Device ( ceConnect).
// 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)
Â
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.
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.
The access to the registry may fail on some Smartphones. In this case, the ErrorOccurred variable is set to True.
