    how to loop through an object?

    Well, you can actually just dump the keys of the namespace. i.e: keys %{'IO::File::'} and check what is defined as a function '&', but I'd personally just make use of the Class::Inspector module: http://search.cpan.org/~adamk/Class-Inspector-1.25/lib/Class/Inspector.pm Scott

    how to loop through an object?

    Hiya, you can still treat it like a hashref even though it's blessed: foreach my $key (keys %{$obj}) { print $key." => ".$obj->{$key}."\n"; } The ref() will tell you want kind of object it is. Did you also want to print out the subs? Cheers, Scott

    What Methond to use?

    I'd try and keep it fairly readable rather than try some convoluted piece of logic that looks funky: int units = num % 10; int tens = num % 100 - units; if(tens == 10) { System.out.println(num+"th"); } else { switch(units) { case 1: System.out.println(num+"st")...

    Inject data into a struct

    hmmm.. my description of a_t.data was misleading. It can be used as a pointer, (i.e. in memcpy etc.) but it will be calculated as an offset from the base of the a_t struct, so the compiler will still prevent you from setting it to NULL.

    Inject data into a struct

    ah... interesting... unfortunately you are at the mercy of the compiler - who ever wrote the original code for the assert must have assumed a_t.data would be a pointer. Whilst it looks like it is, the code produced by the compiler isn't going to use it like that at all, so it will not allow you...

    Inject data into a struct

    doh... I missread the post. forget my previous. You need to allocate the data element in a_t and not define it as an array in the struct: struct a_s{ u_int16_t cmd; u_int16_t dataSize; u_int8_t *data; }; typedef struct a_s a_t; Then you can either stick it on the stack if it's small...

    Inject data into a struct

    Hi P. You are trying to use payload as a pointer, when it is not. You are going to have to do one of two things: 1. re-write the b_s struct to make payload become a pointer to a_t i.e. struct b_s { u_int16_t part; u_int16_t serial; a_t *payload; }; You then need to change all the...

    Can't run main class from JAR file

    Forgot one thing, can you also give us the output from the following if it has no sensitive info: javap -classpath . -verbose com.mycompany.package1.MyClass Cheers, Scott

    Can't run main class from JAR file

    Hi again, Don't worry about the lack of [Loaded ...] messages. They only show when an object is instantiated in the code. I can see the error you are getting in the java.c source code: mainClass = LoadClass(env, classname); if(mainClass == NULL) { /* exception occured */...

    No Internet Access over VLAN

    I have to confess I am a bonafide geek and have been dissecting protocols for over 25 years now, so never really had to look at any tutorials for wireshark. I took a quick look though and this one seems to be pretty good. It initially shows how to capture a simple web transaction and the...

    Can't run main class from JAR file

    Hi, Would it be possible to see the javaCmdOutput.txt if it does not contain sensitive info? Other than that, I'd be keen to know if I can execute the code outside the jar. i.e. after you have unjar'd the file, is it possible to modify the classpath according the the Class-Path line of the...

    Problem with adding variables

    Hi Newbie, You want to actually create an object for the character, not just use a hash. Try the following: Create a file called Character.pm and put the following in it: package Character; #------------------------------------------------------- sub new { my($class, %args) = @_; my...

    No Internet Access over VLAN

    Nice one Arvin! Just glad you got it fixed. To be honest I don't think this a netgear issue. I think the routers you previously had did not correctly handle the subnets after manipulating the DNS queries. Hopefully you can now use your experience with wireshark and port mirroring to solve...

    No Internet Access over VLAN

    Hi Pro, I can see the requests, but no response. It looks like the router is not handling the DNS queries correctly when they are from a different subnet. Can you just confirm one thing though. When you pinged 86.2.106.208 from VLAN3, did it work. You seem to mention that it did, but I...

    No Internet Access over VLAN

    Hi Pro, Doh... I was vague again in my instructions. The trace is fine from the PC on VLAN2. I assume you resolved the IP address for www.google.com each time? You need to do the same with a PC on VLAN3... Sorry, Scott
