  Key path to key (fe 'Software\MyApp')
  Name name of binary value for keep serial port settings (fe 'rs232')

Hello,
Thank for your answer.

I try it but it's not OK.

I try :       nrComm1->SaveConfig(HKEY_LOCAL_MACHINE,"c:\application\exe\","RS232");

And a error is : Le projet Project.exe a déclenché la classe d'exception ERegistryException avec le message 'Failed to set data for ' □□2".

Could you help me?

Hi,

Here is my expertise :

1. nrComm1  must be Activate
2. Your Application should have "Require Administrator" on :  Project > Options > Manifest
3. Today use HKEY_CURRENT_USER   instead of HKEY_LOCAL_MACHINE  (windows 11 constraints).

  nrComm1.SaveConfig(HKEY_CURRENT_USER, 'Software\MyApp', 'rs232');
  nrComm1.LoadConfig(HKEY_CURRENT_USER, 'Software\MyApp', 'rs232');
