regread "" values

[isolation]

I use this func for the registy writing

Func _Rw($key,$dst="",$type="",$val="")
    $a=RegWrite($key,$dst,$type,$val)
    MsgBox(0,$a,@error);
    Return string($a)
EndFunc

I use it with

Call("_Rw","HKEY_LOCAL_MACHINE\SOFTWARE\aaa")

The key is created but it returns @error=0 and returns 0

I've already written about "" values in some Reg* functions that return unusual values but with no helpful answers....

$result = _Rw("HKEY_LOCAL_MACHINE\SOFTWARE\aaa","","REG_SZ")
MsgBox(0,"","@ERROR: " & @ERROR & @CRLF & "$Result: " & $Result)

Func _Rw($key,$dst="",$type="",$val="")
    $a=RegWrite($key,$dst,$type,$val)
    Return SetError(@ERROR,0,$a)
EndFunc

result=0

and at the same time error=0

but only when it's called with 1 argument,

so, by default, the other values are ""

In the help file:

To access the (Default) value use "" (a blank string) for the valuename.

but it returns 0 and error 0

To Write, you always have to specify the type of the value.

Yes, but

RegWrite("HKLM\SOFTWARE\aaa,"","","")

if "" for the "help file" is the default value I use it...

Yes, but

RegWrite("HKLM\SOFTWARE\aaa,"","","")

if "" for the "help file" is the default value I use it...

You must set a type.

but it's optional....

If you wnat to create a Key without a value, you must not specify any further params!

$result = _Rw("HKEY_LOCAL_MACHINE\SOFTWARE\aaa")
MsgBox(0,"","@ERROR: " & @ERROR & @CRLF & "$Result: " & $Result)
Func _Rw($key,$dst="",$type="",$val="")
    Switch @NumParams
        Case 1
            Local $a=RegWrite($key)
                Return SetError(@ERROR,0,$a)
        Case Else
            Local $a=RegWrite($key,$dst,$type,$val)
                Return SetError(@ERROR,0,$a)
    EndSwitch
EndFunc

Ok, I've understood

but if the 2nd,3rd and 4th parameters are all set to the default value...

but it's optional....

If it is optional, it means you can specify it or not specify it.

But if you specify it, it must make sense!
