winqueryreg

Description

value = winqueryreg('name', 'rootkey', 'subkey') returns the key names in rootkey\subkey in a matrix of strings. The first argument is the literal quoted string, 'name'.

If the value retrieved from the registry is a string, winqueryreg returns a string. If the value is a 32-bit integer, winqueryreg returns the value as an integer (int32).

value = winqueryreg('rootkey', 'subkey', 'valname') returns the value for key valname in rootkey\subkey.

value = winqueryreg('rootkey', 'subkey') returns a value in rootkey\subkey that has no value name property.

NoteThe literal name argument and the rootkey argument are case-sensitive. The subkey and valname arguments are not.

supported root keys are: 'HKEY_CLASSES_ROOT', 'HKEY_CURRENT_USER', 'HKEY_LOCAL_MACHINE', 'HKEY_USERS', 'HKEY_DYN_DATA' and 'HKEY_CURRENT_CONFIG'.

Examples

if getos() == 'Windows' then
  winqueryreg 'HKEY_LOCAL_MACHINE' 'HARDWARE\DESCRIPTION\System\CentralProcessor\0\' 'ProcessorNameString'
  mousechar = winqueryreg('name', 'HKEY_CURRENT_USER','control panel\mouse');
  len=size(mousechar);
  for k=1:len(1)
     setting = winqueryreg('HKEY_CURRENT_USER','control panel\mouse', mousechar(k));
     if (mousechar(k)=='') then mousechar(k)='default';,end
     str = msprintf('%s = %s', mousechar(k), string(setting));
