winqueryreg (MATLAB Functions)

Get item from Microsoft Windows registry

Syntax

value = winqueryreg('name', 'rootkey', 'subkey')
value = winqueryreg('rootkey', 'subkey', 'valname')
value = winqueryreg('rootkey', 'subkey')

Description

value = winqueryreg('name', 'rootkey', 'subkey') returns the key names in rootkey\subkey in a cell array 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 of MATLAB type 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.

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

Remarks

This function works only for the following registry value types:

strings (REG_SZ)
expanded strings (REG_EXPAND_SZ)
32-bit integer (REG_DWORD)

Examples

Example 1

Get the value of CLSID for the MATLAB sample 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
