That's scraping of web pages rather than a Windows gui.

Hi, I have a need to screen scrape a legacy windows application. Can anyone give me some pointers as to how this can be done with C# .Net? All guidance offered will be warmly appreciated.

Hi, I see there's no reply to this. Do I need to provide more information?

Hi, I am passing a VBScript Object to a C# assembly and am getting the following error output: "Unable to cast COM object of type 'Agents.AgentClass' to interface type 'Agents._Agent'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{315DF678-45D7-4A60-9A50-C9E83672A5E5}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))." I'd appreciate it if someone can explain what is going on here and how I can fix it? I am confused... Note: I have tried changing the method header to accept type Agents._Agent but that causing the method call in vbscript to fail completely. Changing the type to Agents.Agent (another available type) generates a similar error. Kind Regards, Dave

Hi, I'm just beginning work on an assembly which, amongst other things, will perform some transformations and other operations on objects passed from COM. I've created a stub assembly to receive these objects to see what they look like in the debugger. However, because they're passed as "Object" I am not able to see any of their methods or properties. Can someone advise me on how I can get a view of the methods and properties of these objects so that I can better understand what I'm dealing with? All help and advice will be warmly received. Kind Regards, Dave

Hi, I need to determine the parent class from which a particular subclass is derived. Could someone kindly explain to me how I can access that information please? Regards, Dave

I'm using .Net 3.5 so it should be there. I'm wondering whether there's something about my project config that's getting in the way that I'm not aware of. Target framework is marked as 3.5 but perhaps there's more I need to consider...

Regards, Dave

Take a look at www.ikvm.net. That might help though i expect the newness of the java release will cause issues.

Hi, I'm tryig to add a project reference to Microsoft.ServiceModel.Channels.dll, specifically to access the UnSupportedOperationException exception class. However, I can't see it in the list of .Net references. I'm surprised not to find this dll in the frameowrk list. Can someone explain what I should be referencing in order to access UnSupportedOperatinException?

Hi, Could anyone tell me whether there is a C# equivalent of the java CharArrayBuilder class? Regards, Dave

Regards, Dave

Hi, Can anyone direct me to the C# equivalent of the ObjectOutput and ObjectInput interfaces in java?

Regards, Dave

That's "an" answer but I don't think it's "the" answer. The rason is that some objects override their base hashcode. And in this case it's the base hashcode that's needed. That's what the Java class returns, if I understand it corrctly. Regards, Dave

Hi, Does anyone know of a direct C# equivalent, or implementation, of java's System.identiyHashCode method? Regards, Dave

As I'm not a java developer what is your interpretation of what that block of code is doing? That's one the problems I have. I'm trying to convert the code without being able to interactively debug it to see what it does.

Regards, Dave

Hi All, I've beenconverting some java classes to C# and am getting buffeted by headwinds with the network code conversion. Here is a block of code that has me at a loss for now:

    try {
        Enumeration; interfaces = NetworkInterface.getNetworkInterfaces();
        while (interfaces.hasMoreElements()) {
            Enumeration addresses = interfaces.nextElement().getInetAddresses();
            while (addresses.hasMoreElements()) {
                InetAddress addr = addresses.nextElement();
                if (!addr.isLoopbackAddress()) {
                    address = addr.getAddress();
                }
            }
        }
    }

I've interpreted the statement:

Enumeration<NetworkInterface>; interfaces = NetworkInterface.getNetworkInterfaces();

as:

NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();

...which return a list of network interfaces on the host. However, the statement:

Enumeration<InetAddress> addresses = interfaces.nextElement().getInetAddresses();

...is giving me more trouble. I know the type that I want to create (IPHostEntry - I believe that's correct) but I can see no way to identify the IP Addresses associated with a given network interface (when the host is multi-homed). The C# classes that I have seen all seem to generically assume that the host has 1 interface which may have more than 1 IP Address. So my questions is, in a nutshell, if a host has multiple network interfaces how does one identify the ip addresses associated with each interface? All suggestions warmly welcomed...

Regards, Dave

Hi, I think I've resolved this. By setting the type as IPAddress the member "GetAddressBytes" can be used to convert the address to bytes matching the type of the variable "address". Thanks for your tip, it pointed me in the right directions. That said, I've hit another problem which seems to be a bit trickier. I need to determine the IP addresses associated with the network interfaces of the multi-homed host the code is running on. I am capturing the available interfaces as follows: NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces(); I then want to loop through the entries and for each one load it's associated IP Addresses into an IPHostEntry instance (or similar). However, I don't see any way to determine the list of ip addresses associated with a particular network interface returned by the foreach loop as it iterates through "interfaces". How is this done?

Regards, Dave

Hi, Thanks for that. A couple of questions / observations: 1. The C# documentation refers to the resolve method as being obsolete. 2. The java type of "address" is byte[]. The method returns a "raw" ip address. The C# equivalents, including Dns.resolve return an IPAddress[] type which i assume isn't raw. Can C# return raw addresses? I assume the type to use is c# byte[]... Additionally, I'm unclear as to what the java documentation means by a raw ip address. Can you clarify? I'm expecting that it means that I the IPAddress[] type is not the correct type for this operation.

Regards, Dave

Hi, Can anyone tell me the C# equivalent ofthe following java code? address = InetAddress.getLocalHost().getAddress(); I've not done anything with networking in C# before but from an admittedly quick inspection it does appear that the java implementation makes more intuitive sense. I'd say it's more feature rich too but I haven't ben able to make complete sense yet of what C# has to offer. Regards, Dave

Hi, I'm working to convert some java code to C#. I'm struggling to determine what is the equivalent C# statement to the Java "UnknownHostException". Can anyone point me in the right direction?

Hmmn. Does the lack of replies mean that this type of resource doesn't exist?
