Registry Key Empty?

Recommended Posts

pedrosland

Hi

I am very new to AutoIt and have tried a few things (including Google ^_^ ) but can't seem to get anything to work. I want to tell if a registry key (folder) is empty. Could someone post some sample script please?

Thanks,

Pedro.

Lookup RegEnumKey() and RegEnumVal() in the help file. You can use a counter and increase it if any of the functions mentioned result in something other than error, then, if the counter is 0, the registry key is empty of values or sub-keys.

Do you have the value you are looking for?

Check out:

RegRead ( "keyname", "valuename" )

You can use RegEnumKey / RegEnumVal with index 1

Func _RegKeyIsEmpty($Key)
       ; Prog@ndy
    Local $result = 0
    RegEnumVal($Key,1)
    If @error = -1 Then $result += 1
    RegEnumKey($Key,1)
    If @error = -1 Then $result += 2
    Return SetError($result=0,0,$result)
EndFunc

ConsoleWrite(_RegKeyIsEmpty("HKEY_CURRENT_USER\Printers") & @CRLF) ; 0: keys and values
ConsoleWrite(_RegKeyIsEmpty("HKEY_CURRENT_USER\Network") & @CRLF) ; 1: only Keys
ConsoleWrite(_RegKeyIsEmpty("HKEY_CURRENT_USER\Columns") & @CRLF) ; 2: only Values
ConsoleWrite(_RegKeyIsEmpty("HKEY_CURRENT_USER\AppEvents") & @CRLF) ; 3: no Keys, no Values
