I'm not able to re-run the test just now ... but will later this evening.<br><br>Actually ... the message I put below was copied directly from the output of the soap fault message ... so I did not modify the message in any way. Not sure why it was reported that way. I'll investigate further.<br><br>I am pretty sure I am not using a IVirtualBox::getMachine ref though I may have made such a mistake and not realized it. Later tonight when I get a chance to look at the code I will double-check.<br><br><br>Thanks again,<br>Joe<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br><div style="font-family: arial,helvetica,sans-serif; font-size: 10pt;"><font face="Tahoma" size="2"><hr

I know it can be done since VBoxManage is able to ... but I'm wondering if this could possibly be a
vboxwebsrv problem. Essentially ... the steps I use are:<br>> <br>> 1) Instantiate a new Session object<br>> 2) Using this session object ... try to open a new session (openSession)<br>> 3) If getting a new session fails ... try to open an existing session (openExistingSession)<br>> 3) With the opened session object ... get the machine object reference (ISession::machine)<br>> 4) Using the machine reference ... enumerate the guest properties (ISession::enumerateGuestProperties)<br>> <br>> If the VM is not running ... it works perfectly. If the VM is running ... a runtime exception is thrown. The error thrown is:<br>> "VirtualBox error: Internal application error (0x2147500037)"<br><br>Printing 0x in front of a number doesn't make it hex ;)<br><br>This is error 0x80004005 = E_FAIL.<br><br>From the looks you're not doing what you claim, as exactly this sequence works fine in
VBoxManage. Sure that you're not accidentally using an IMachine reference returned by IVirtualBox::getMachine?<br><br>Klaus<br><br>> <br>> Using the same Machine reference object I can retrieve other machine specific information ... so I know the machine ref is valid (additionally, the UUID on the machine ref matches the UUID of the VM).<br>> <br>> I am also able to use this same approach to getting a session for both a non-running and running VM to start/stop/pause or otherwise manage a VM. As frequently suggested (<smile>) ... I have looked over how VBoxManage does it ... and I am unable to see a difference between how VBoxManage retreives the information when compared to they way I do.<br>> <br>> I'm sure I must be doing something wrong ... but it sure does not seem very obvious.<br>> <br>> Anyone have any suggestions they can offer ?<br>> <br>> <br>> Thanks,<br>> Joe<br>> <br>> <br>>
