Running UpdateService from a service

[Charles_Donnis]

I am trying to create a Windows service based application that uses UpdateService. However I cannot get it to work, it fails when i call AutoUpdate in both silent and non silent modes even if the service is logged in as an Administrator on the machine. If i run AutoUpdate from a standalone program it runs fine.

Has anyone got any ideas why this maybe happening?

Thanks

Could you post the source code that you are using to check for updates? That way, we can get a better idea of whats going on. I know many of us are able to get AutoUpdate working, myself included. It must be a simple coding mistake somewhere

The code I use to run from the windows service and the code I use that runs the standalone program is exactly the same. The service in fact launches an executable that does the update and I can run that update as a standalone application. When I run it as standalone application it works, when I let the service launch it it doesnt. AutotUpdate fails when it runs from the service, and HRESULT is a very large -ve number which doesnt correlate to any windows error message.

Here is the code:

USES_CONVERSION;
VARIANT_BOOL bUpdateInitiated = VARIANT_FALSE;
CComBSTR productCode(szProductCode);
VARIANT_BOOL varbSilent;
if(bSilent)
{
varbSilent=VARIANT_TRUE;
}
else
{
varbSilent=VARIANT_FALSE;
}
HRESULT hr = m_spAgent->AutoUpdate(productCode, varbSilent, 0, 0,&bUpdateInitiated);
if(bUpdateInitiated==VARIANT_FALSE)
{
return (FALSE);
}
return TRUE;

It doesnt matter if I run the service as Admin or local system.

Oh darn, I misread your earlier post. I didn't see you have two distinct setups here...a Windows service based application and a standalone application. If you can get it to work on a standalone application, then I'm stumped...I thought you just couldn't get anything to work at all.

I'd investigate this more, make a simple test case program, and then open up a MySupport request on this if it is a bug. Sorry I can't be of more help. 😞
