  • Resolving the WMI DNS Host Name

    - by Stephen Murby
    I am trying to make a comparison between a machine name i have retrieved from AD, and the DNS Host Name i want to get using WMI from the machine. I currently have: foreach (SearchResult oneMachine in allMachinesCollected) { pcName = oneMachine.Properties["name"][0].ToString(); ConnectionOptions setupConnection = new ConnectionOptions(); setupConnection.Username = USERNAME; setupConnection.Password = PASSWORD; setupConnection.Authority = "ntlmdomain:DOMAIN"; ManagementScope setupScope = new ManagementScope("\\\\" + pcName + "\\root\\cimv2", setupConnection); setupScope.Connect(); ObjectQuery dnsNameQuery = new ObjectQuery("SELECT * FROM Win32_ComputerSystem"); ManagementObjectSearcher dnsNameSearch = new ManagementObjectSearcher(setupScope, dnsNameQuery); ManagementObjectCollection allDNSNames = dnsNameSearch.Get(); string dnsHostName; foreach (ManagementObject oneName in allDNSNames) { dnsHostName = oneName.Properties["DNSHostName"].ToString(); if (dnsHostName == pcName) { shutdownMethods.ShutdownMachine(pcName, USERNAME, PASSWORD); MessageBox.Show(pcName + " has been sent the reboot command"); } } } } But i get a ManagementException dnsHostName = oneName.Properties["DNSHostName"].ToString(); << here saying not found. Any ideas?

  • How to write this snippet in Python?

    - by morpheous
    I am learning Python (I have a C/C++ background). I need to write something practical in Python though, whilst learning. I have the following pseudocode (my first attempt at writing a Python script, since reading about Python yesterday). Hopefully, the snippet details the logic of what I want to do. BTW I am using python 2.6 on Ubuntu Karmic. Assume the script is invoked as: script_name.py directory_path import csv, sys, os, glob # Can I declare that the function accepts a dictionary as first arg? def getItemValue(item, key, defval) return !item.haskey(key) ? defval : item[key] dirname = sys.argv[1] # declare some default values here weight, is_male, default_city_id = 100, true, 1 # fetch some data from a database table into a nested dictionary, indexed by a string curr_dict = load_dict_from_db('foo') #iterate through all the files matching *.csv in the specified folder for infile in glob.glob( os.path.join(dirname, '*.csv') ): #get the file name (without the '.csv' extension) code = infile[0:-4] # open file, and iterate through the rows of the current file (a CSV file) f = open(infile, 'rt') try: reader = csv.reader(f) for row in reader: #lookup the id for the code in the dictionary id = curr_dict[code]['id'] name = row['name'] address1 = row['address1'] address2 = row['address2'] city_id = getItemValue(row, 'city_id', default_city_id) # insert row to database table finally: f.close() I have the following questions: Is the code written in a Pythonic enough way (is there a better way of implementing it)? Given a table with a schema like shown below, how may I write a Python function that fetches data from the table and returns is in a dictionary indexed by string (name). How can I insert the row data into the table (actually I would like to use a transaction if possible, and commit just before the file is closed) Table schema: create table demo (id int, name varchar(32), weight float, city_id int); BTW, my backend database is postgreSQL

  • How to corelate gtk.ListStore items with my own models

    - by Victor Stanciu
    Hello, I have a list of Project objects, that I display in a GTK TreeView. I am trying to open a dialog with a Project's details when the user double-clicks on the item's row in the TreeView. Right now I get the selected value from the TreeView (which is the name of the Project) via get_selection(), and search for that Project by name in my own list to corelate the selection with my own model. However, this doesn't feel quite right (plus, it assumes that a Project's name is unique), and I was wondering if there is a more elegant way of doing it.

  • C++ initializing constants and inheritance

    - by pingvinus
    I want to initialize constant in child-class, instead of base class. And use it to get rid of dynamic memory allocation (I know array sizes already, and there will be a few child-classes with different constants). So I try: class A { public: const int x; A() : x(0) {} A(int x) : x(x) {} void f() { double y[this->x]; } }; class B : A { B() : A(2) {} }; Pretty simple, but compiler says: error C2057: expected constant expression How can I say to compiler, that it is really a constant?

  • Generating random numbers in C

    - by moonstruckhorrors
    While searching for Tutorials on generating random numbers in C I found This Topic When I try to use the rand() function with parameters, I always get the random number generated 0. When I try to use the rand() function with parameters, I always get the value 41. And whenever I try to use arc4random() and random() functions, I get a LNK2019 error. Here's what I'm doing: #include <stdlib.h> int main() { int x; x = rand(6); printf("%d", x); } This code always generate 41. Where am I going wrong?? P.S. : I'm running Windows XP SP3 and using VS2010 Command Prompt as compiler. P.P.S. : Took me 15 minutes to learn how to format properly.

  • What benefits can Java developer have from moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse on it, so there will be no big difference. Guys, who use Java on *NIX, could you please give me some real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • Linked List push()

    - by JKid314159
    The stack is initialized with a int MaxSize =3. Then I push one int onto the list. " Pushed:" is returned to the console. Program crashes here. I think my logic is flawed but unsure. Maybe an infinite loop or unmet condition? Thanks for your help. I'm trying to traverse the list to the last node in the second part of the full() method. I implemented this stack as array based so must implement this method full() as this method is inside of main class. while(!stacker.full()) { cout << "Enter number = "; cin >> intIn; stacker.push(intIn); cout << "Pushed: " << intIn << endl; }//while Call to LinkListStack.cpp to class LinkList full(). int LinkList::full() { if(head == NULL) { top = 0; } else { LinkNode * tmp1; LinkNode * tmp2; tmp1 = head; while(top != MaxSize) { if(tmp1->next != NULL){ tmp2 = tmp1->next; tmp1 = tmp2; ++top; }//if }//while }//else return (top + 1 == MaxSize); }

  • Would it be faster to use CMS for building the first site in ASP.NET?

    - by rem
    I need an opinion and advise from experienced ASP.NET people, what way to go. Assuming that a developer has some practical background with HTML/JavaScript/PHP on one side and some .NET/C#/WPF experience on the other side. No previous hands on experience with ASP.NET - only theory and some read books on the topic. The task is to build ASP.NET web site with User Managment functionality (user authentication, user account, user buying history, user points and so on) and E-commerce functionality with shopping cart, checkout and all needed for this. Is it worth, i.e. will it be faster, more reliable and secure in the result to use a ASP.NET CMS system (for example Sitefinity from Telerik as declared developer friendly) to build such first site? In what case the learning curve will be more steep and it will take more time to achieve similar results? Notes to take into consideration: 1) Price of the CMS matters not very much 2) E-commerce module should be written from scratch in any case (and integrated in case of using CMS) due to very specific requirements

  • Java: what is the class for the isBinary-method?

    - by HH
    I am accustomed to java.io.* and java.util.* but not to the tree: com.starbase.util Class FileUtils java.lang.Object | +--com.starbase.util.FileUtils Source. So which class should I import to use the isBinary-method? Do I do "import java.lang.Object;" or "import java.lang.Object.com.starbase.util.FileUtils;"?

  • Scala Tuple Deconstruction

    - by dbyrne
    I am new to Scala, and ran across a small hiccup that has been annoying me. Initializing two vars in parallel works great: var (x,y) = (1,2) However I can't find a way to assign new values in parallel: (x,y) = (x+y,y-x) //invalid syntax I end up writing something like this: val xtmp = x+y; y = x-y; x = xtmp I realize writing functional code is one way of avoiding this, but there are certain situations where vars just make more sense. I have two questions: 1) Is there a better way of doing this? Am I missing something? 2) What is the reason for not allowing true parallel assignment?

  • wsgi-served page does not refresh

    - by Steve
    I recently got my first app to work in uWSGI with Cherokee. I used the following code taken from the uWSGI docs: def application(environ, start_response): start_response('200 OK', [('Content-Type', 'text/plain')]) yield 'Hello World\n' The page correctly reads Hello World. When I change that text to New Thing and refresh, nothing changes. What am I forgetting? What I've tried: clearing browser history and cache stopping and starting Cherokee

  • Proper indentation for Python multiline strings

    - by ensnare
    What is the proper indentation for Python multiline strings within a function? def method: string = """line one line two line three""" or def method: string = """line one line two line three""" or something else? It looks kind of weird to have the string hanging outside the function in the first example. Thanks.

  • How to sanely read and dump structs to disk when some fields are pointers?

    - by bp
    Hello, I'm writing a FUSE plugin in C. I'm keeping track of data structures in the filesystem through structs like: typedef struct { block_number_t inode; filename_t filename; //char[SOME_SIZE] some_other_field_t other_field; } fs_directory_table_item_t; Obviously, I have to read (write) these structs from (to) disk at some point. I could treat the struct as a sequence of bytes and do something like this: read(disk_fd, directory_table_item, sizeof(fs_directory_table_item_t)); ...except that cannot possibly work as filename is actually a pointer to the char array. I'd really like to avoid having to write code like: read(disk_df, *directory_table_item.inode, sizeof(block_number_t)); read(disk_df, directory_table_item.filename, sizeof(filename_t)); read(disk_df, *directory_table_item.other_field, sizeof(some_other_field_t)); ...for each struct in the code, because I'd have to replicate code and changes in no less than three different places (definition, reading, writing). Any DRYer but still maintainable ideas?

  • Defining a class with specific style dynamically in jQuery

    - by Acorn
    Is it possible to define a class with specific style attributes dynamically with jQuery, rather than setting the style of all elements with that class? I could set the attributes of the class at the end of the script once all the elements have been created, but is that the best way to go about it? If I define the style of the class with $('.class').css('property','value'); at the beginning of the script, nothing would happen because the elements with class .class haven't been created yet, right?

  • How to access child div elements under a given condition with javascript?

    - by hlovdal
    My main question is to calculate the last alert message, but any other information is also welcome. I am trying to learn javascript (to use with greasemonkey later), but I am struggling a bit to grasp the DOM and how to process it. <html> <head> <script type="text/javascript"> function my_test() { var elements = document.getElementsByTagName("div"); // prints "found [object HTMLCollection] with length 8" alert("found " + elements + " with length " + elements.length); // prints "0:[object HTMLDivElement]" alert("0:" + elements[0]); // how to calculate the following? alert("for intereting one is AAAA and three is CCCC"); } </script> </head> <body> <div class="interesing"> <div class="one">AAAA</div> <div class="two">BBBB</div> <div class="three">CCCC</div> </div> <div class="boring"> <div class="one">1111</div> <div class="two">2222</div> <div class="three">3333</div> </div> <input type="button" onclick="my_test()" value="my test" </body> </html> So elements is now an array of elements and I can access each of them individually. But where can I find what methods/properties these elements have?
