Re: Remolty access to the registry with WMI

Because I receive this:

org.jawin.COMException: 80070057: The parameter is incorrect.
    at org.jawin.marshal.GenericStub.dispatchInvoke0(Native Method)
    at
org.jawin.marshal.GenericStub.dispatchInvoke(GenericStub.java:201)
    at org.jawin.DispatchPtr.invokeN(DispatchPtr.java:587)
    at org.jawin.DispatchPtr.invokeN(DispatchPtr.java:555)


Which I don't when I use:

Variant.ByrefHolder names = new Variant.ByrefHolder(new String());
Variant.ByrefHolder types = new Variant.ByrefHolder(new Integer(0));

But I agree this is strange.

How about using arrays? i.e. :
 names = new Variant.ByrefHolder(new String[0]);
 types = new Variant.ByrefHolder(new int[0]);

I progress in my investigation.

I call the method EnumValues on the StdRegProv object.

The method has the following signature:

uint32 EnumValues([IN] uint32 hDefKey = 2147483650, [IN] string
sSubKeyName, [out] string sNames[], [out] sint32 Types[])


I try to do something like that:

Variant.ByrefHolder names = new Variant.ByrefHolder(new String());
Variant.ByrefHolder types = new Variant.ByrefHolder(new Integer(0));
wbemObject.invokeN("EnumValues ", new Object[] {
RegistryConstants.HKEY_LOCAL_MACHINE,
"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall", names,
types});

but after names.getRef() is null

Any idea?

Tx
Eric

Subject: [JAWIN] Remolty access to the registry with WMI

Hi,

I try to access remotely the registry with WMI:

ISWbemLocator wbemLocator = new
ISWbemLocator("WbemScripting.SWbemLocator");
ISWbemServices wbemServices = wbemLocator.ConnectServer("10.7.1.22",
"root/default", "user", "password", "", "", 0, null);

            ISWbemObject wbemObject = wbemServices.Get("StdRegProv", 0,
null);
            System.out.println(wbemObject.GetObjectText_(0).toString());

The System.out.println displays the StdRegProv class definition:

            [Locale(1033), dynamic: ToInstance, provider("RegProv")]
class StdRegProv
{
    [implemented, static] uint32 CreateKey([IN] uint32 hDefKey =
2147483650, [IN] string sSubKeyName);
    [implemented, static] uint32 DeleteKey([IN] uint32 hDefKey =
2147483650, [IN] string sSubKeyName);

            ..

}

As my knowledge of COM is very limited, I'm basically stuck here. In
VBscript samples, it seems very easy:

            Set objLocator = CreateObject("WbemScripting.SWbemLocator")
Set objService = objLocator.ConnectServer( strComputer, "Root\Default",
strUserName, strPassword )
Set objRegistry = objService.Get( "StdRegProv" )
objRegistry.DeleteKey(HKEY_LOCAL_MACHINE,
"SYSTEM\CurrentControlSet\Services\admin51-serv")

Has someone already done this? How can I call EnumValues on my object
wbemObject ?

Thanks for you help
Eric
