Question

I’m trying to register a new UPNP device(and trying to understand how it works by the way).

For now, I’m just trying to create a simple test, to have something working and build from there.

I’m using the UPnP Device host for now, I’ve the following code:

IUPnPRegistrar registrar = (IUPnPRegistrar)new UPnPRegistrarClass();
String description = GetDescription();
String path = GetPath();
registrar.RegisterDevice(description, "Test1", "Init", "Container", path, 900);

The GetDescription method return this:

<?xml version="1.0" encoding="utf-8" ?>
<root xmlns="urn:schemas-upnp-org:device-1-0">
    <specVersion>
        <major>1</major>
        <minor>0</minor>
    </specVersion>
    <device>
        <UDN>@@UDN@@</UDN>
        <friendlyName>Test device</friendlyName>
        <deviceType>urn:schemas-upnp-org:device:XmsHostService:1</deviceType>
        <manufacturer>Test</manufacturer>
        <manufacturerURL>http://www.test.com</manufacturerURL>
        <modelName>Test model name</modelName>
        <modelNumber>0.1</modelNumber>
        <modelDescription>Test device</modelDescription>
        <modelURL>http://www.test.com/test-model-url</modelURL>
        <serialNumber>0000001</serialNumber>
        <UPC>00000-00001</UPC>
        <serviceList>
            <service>
                <serviceType>urn:schemas-upnp-org:service:XmsHost:1</serviceType>
                <serviceId>urn:upnp-org:serviceId:XmsHost</serviceId>
                <controlURL></controlURL>
                <eventSubURL></eventSubURL>
                <SCPDURL>serviceDescription.xml</SCPDURL>
            </service>
        </serviceList>
    </device>
</root>

And my C:\upnphost\service.xml contains the following code:

<?xml version="1.0" encoding="utf-8"?>
<scpd xmlns="urn:schemas-upnp-org:service-1-0">
    <specVersion>
        <major>1</major>
        <minor>0</minor>
    </specVersion>
    <actionList>
        <action>
            <name>GetPort</name>
            <argumentList>
                <argument>
                    <name>_ReturnValue</name>
                    <direction>out</direction>
                    <retval />
                    <relatedStateVariable>A_ARG_TYPE_GetPort_RetType</relatedStateVariable>
                </argument>
            </argumentList>
        </action>
    </actionList>
    <serviceStateTable>
        <stateVariable sendEvents="no">
            <name>A_ARG_TYPE_GetPort_RetType</name>
            <dataType>ui4</dataType>
        </stateVariable>
        <stateVariable sendEvents="no">
            <name>Port</name>
            <dataType>ui4</dataType>
        </stateVariable>
    </serviceStateTable>
</scpd>

So, first, does this xml code looks right?

When I call the register device, I got this exception:

    System.ArgumentException was unhandled
  Message=Value does not fall within the expected range.

  InnerException: 

But I don’t see what can be wrong, the 900 is the min value accepted. Other linked question: I know that I have to implement the IUPnPDeviceControl interface and insert in my previous code instead of Test1, but I don’t know what I should return in the GetServiceObject

EDIT
Here is the GetDescription method:

private string GetDescription()
{
    string xml = File.OpenText("DeviceDescription.xml").ReadToEnd();
    xml = xml.Replace("@@UDN@@", "uuid:" +Guid.NewGuid().ToString());
    return xml;
}

EDIT 2
I tried, as recommended to remove all non-mandatory properties:

<?xml version="1.0" encoding="utf-8" ?>
<root xmlns="urn:schemas-upnp-org:device-1-0">
    <specVersion>
        <major>1</major>
        <minor>0</minor>
    </specVersion>
    <device>
        <UDN>@@UDN@@</UDN>
        <friendlyName>Test device</friendlyName>
        <deviceType>urn:test-com:device:HostDevice:1</deviceType>
        <manufacturer>Test</manufacturer>
        <modelName>Test model name</modelName>
    </device>
</root>

But I still have the exact same error

Edit 3
I did found that there is an utility to check the good structure of the service xml file(not the device :() here: http://msdn.microsoft.com/en-us/library/aa381938(v=vs.85).aspx You can use it with VS studio command prompt: validatesd.exe. It validates my service

Answer 1

The COM Object progid must correspond to something real, ie: “Test1” must be a valid COM object registered in the current registry for the RegisterDevice call to succeed.
