Syntax

Description

valnames = winqueryreg('name','rootkey','subkey') returns all value names in rootkey\subkey of Microsoft^® Windows^® operating system registry to a cell array of character vectors. The first argument is the literal quoted string, 'name'.

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

If the value retrieved from the registry is a string, winqueryreg returns a character vector. If the value is a 32-bit integer, winqueryreg returns the value as an integer of the MATLAB^® type int32.

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

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

Examples

Example 1

Get the value of CLSID for the MATLAB sample Microsoft COM control mwsampctrl.2:

winqueryreg 'HKEY_CLASSES_ROOT' 'mwsamp.mwsampctrl.2\clsid'

ans =
   {5771A80A-2294-4CAC-A75B-157DCDDD3653}

Example 2

Get a list in variable mousechar for registry subkey Mouse, which is under subkey Control Panel, which is under root key HKEY_CURRENT_USER.

mousechar = winqueryreg('name','HKEY_CURRENT_USER','control panel\mouse');

For each name in the mousechar list, get its value from the registry and then display the name and its value:

for k = 1:length(mousechar)
   setting = winqueryreg('HKEY_CURRENT_USER','control panel\mouse', mousechar{k});
   str = sprintf('%s = %s',mousechar{k},num2str(setting));
   disp(str)
end
