    - by lfx
    Hi, I developing program witch have to write some data in file whom are stored in network computer witch are protected by password. Now I'm doing this way - open connection with cmd then write data. static bool ConnectToSrv() { String myUser = "domain.local\\user"; String myPass = "pwd"; String cmdString = "net use \\\\otherPC\\folder\\ /user:" + myUser + " " + myPass; try { ManagementClass processClass = new ManagementClass("Win32_Process"); object[] methodArgs = { cmdString, null, null, 0 }; object result = processClass.InvokeMethod("Create", methodArgs); return true; } catch (System.Exception error) { return false; } } public void writeDate(string data){ } I believe there must by better way.

  • Framework/tool for processing C++ unit tests with numerical output

    - by David Claridge
    Hi, I am working on a C++ application that uses computer vision techniques to identify various types of objects in a sequence of images. The (1000+) images have been hand-classified, so we have an XML file for each image containing a description of where the objects are actually located in the images. I would like to know if there is a testing framework that can understand/graph results from tests that are numeric, in this case some measure of the error in the program's classification of the images, rather than just pass/fail style unit tests. We would like to use something like CDash/CTest for running these automated tests, and viewing over time how improvements to the vision algorithms are causing the images to be more correctly classified. Does anyone know of a tool/framework that can do this?

    - by commanderz
    Hi, I have a program which writes its output using ofstream. Everything works perfectly fine on Windows when compiled with Visual Studio, but it only writes empty file on Linux when compiled with GCC. ofstream out(path_out_cstr, ofstream::out); if(out.bad()){ cout << "Could not write the file" << flush; } else{ cout << "writing"; out << "Content" << endl; if(out.fail()) cout << "writing failed"; out.flush(); out.close(); } The directory which is being writen into has 0777 privileges.

  • Simple addition calculator in python

    - by Krysten
    I built a very simple addition calculator in python: #This program will add two numbers entered in by the user print "Welcome!" num1 = input("Please enter in the first number to be added.") num2 = input("Please enter in the second number to be added.") sum = num1 + num2 print "The sum of the two numbers entered is: ", sum I haven't setup python yet, so I'm using codepad.org (an online compiler). I get the following error: Welcome! Please enter in the first number to be addeded.Traceback (most recent call last): Line 5, in num1 = input("Please enter in the first number to be addeded.") EOFError

  • Referencing other modules in atexit

    - by Dmitry Risenberg
    I have a function that is responsible for killing a child process when the program ends: class MySingleton: def __init__(self): import atexit atexit.register(self.stop) def stop(self): os.kill(self.sel_server_pid, signal.SIGTERM) However I get an error message when this function is called: Traceback (most recent call last): File "/usr/lib/python2.5/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/home/commando/Development/Diploma/streaminatr/stream/selenium_tests.py", line 66, in stop os.kill(self.sel_server_pid, signal.SIGTERM) AttributeError: 'NoneType' object has no attribute 'kill' Looks like the os and signal modules get unloaded before atexit is called. Re-importing them solves the problem, but this behaviour seems weird to me - these modules are imported before I register my handler, so why are they unloaded before my own exit handler runs?

  • algorithmes with no executable example code

    - by gcc
    [link] http://stackoverflow.com/questions/2932016/parsing-of-mathematical-expressions (problem has been told before) ** program is to create the infix tree for the given math expression.** if the expression is given completely paranthesized then the out put is fine but when there are no paranthesis or some part paranthesized then the out put is wrong. cant get the idea how to solve. my problem is told above. I have some algorithm to solve my problem, but I have no simple code which will be guide for me. Can anyone give me simple code (not working code) so that I will try working to understand.(for a 3 hours ,I have been searching and reading some text to understand algorithm which is told above.Actually,there is no example code investigating how it is working. Can anyone send me example which is written in c not other language.

  • Optional parens in Ruby for method with uppercase start letter?

    - by RasmusKL
    I just started out using IronRuby (but the behaviour seems consistent when I tested it in plain Ruby) for a DSL in my .NET application - and as part of this I'm defining methods to be called from the DSL via define_method. However, I've run into an issue regarding optional parens when calling methods starting with an uppercase letter. Given the following program: class DemoClass define_method :test do puts "output from test" end define_method :Test do puts "output from Test" end def run puts "Calling 'test'" test() puts "Calling 'test'" test puts "Calling 'Test()'" Test() puts "Calling 'Test'" Test end end demo = DemoClass.new demo.run Running this code in a console (using plain ruby) yields the following output: ruby .\test.rb Calling 'test' output from test Calling 'test' output from test Calling 'Test()' output from Test Calling 'Test' ./test.rb:13:in `run': uninitialized constant DemoClass::Test (NameError) from ./test.rb:19:in `<main>' I realize that the Ruby convention is that constants start with an uppercase letter and that the general naming convention for methods in Ruby is lowercase. But the parens are really killing my DSL syntax at the moment. Is there any way around this issue?

  • Jquery - Convert ascii chars back to HTML

    - by sdmiller
    I am reading data from an html file to load into a div. The problem I am having is, the program that writes the html files is converting to <br /> SO when I execute $('#items').load('/News/list.aspx'); it displays as a string on my page instead of reading it as a page break. I have tried to read the above file into a variable to do a string replace on the <br /> but it doesn't seem to work. Any suggestions?

  • Help with output generated by this C code using fork()

    - by Seephor
    I am trying to figure out the output for a block of C code using fork() and I am having some problems understanding why it comes out the way it does. I understand that when using fork() it starts another instance of the program in parallel and that the child instance will return 0. Could someone explain step by step the output to the block of code below? Thank you. main() { int status, i; for (i=0; i<2; ++i){ printf("At the top of pass %d\n", i); if (fork() == 0){ printf("this is a child, i=%d\n", i); } else { wait(&status); printf("This is a parent, i=%d\n", i); } } }

  • "Winamp style" spectrum analyzer

    - by cvb
    I have a program that plots the spectrum analysis (Amp/Freq) of a signal, which is preety much the DFT converted to polar. However, this is not exactly the sort of graph that, say, winamp (right at the top-left corner), or effectively any other audio software plots. I am not really sure what is this sort of graph called (if it has a distinct name at all), so I am not sure what to look for. I am preety positive about the frequency axis being base two exponential, the amplitude axis puzzles me though. Any pointers?

  • Index out of bounds exception in c#

  • Trace large C++ code base?

    - by anon
    Problem: I have just inherited this 200K LOC source code base. There's only a small part of it I need (and I want to rip all else out). What I would like to do is to be able to: 1) run the program a few times 2) have something (here's where you come in) record which lines of code gets executed 3) then rip out all the irrelevant lines of code I realize this has "problems" in the forms of "different args will take different paths"; but for my needs, it's very specific, and I just want something ot get me started on the right line of for ripping stuff out (I'll fine tune those special cases later). Thanks!

  • Android -- Object Creation/Memory Allocation vs. Performance

    - by borg17of20
    Hello all, This is probably an easy one. I have about 20 TextViews/ImageViews in my current project that I access like this: ((TextView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Text)).setText(""); //or ((ImageView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Right)).setVisibility(View.INVISIBLE); My question is this, am I better off, from a performance standpoint, just assigning these object variables? Further, am I losing some performance to the constant "search" process that goes on as a part of the findViewById(...) method? (i.e. Does findsViewById(...) use some sort of hashtable/hashmap for look-ups or does it implement an iterative search over the view hierarchy?) At present, my program never uses more than 2.5MB of RAM, so will assigning 20 or so more object variables drastically affect this? I don't think so, but I figured I'd ask. Thanks.

  • Associate List<T>.Remove to an event in C#?

    - by Uri
    Hi guys, I have a Products:List<Product> class. I'd like to make it so that every time that I remove an item from that list, my program decreases a counter. Is there a way to do it without overriding the Remove method or decreasing it manually? And if there is none, anybody knows where I can find the code for the Remove method? Thanks! I thought about associating the Remove method to an event, but I don't know how to do it without overriding it or creating another method with the Remove method inside it. Excuse me for my ignorance, but I'm just getting into OOP programming.

  • Capturing network traffic on Linux

    - by Quandary
    Question: I have one Windows laptop, one Linux laptop and a wireless router. Now I want to "investigate" the hotmail/windows live protocol. What I want to do is route network traffic from the windows laptop via ethernet to the linux laptop, capture it on the Linux computer, forward it wirelessly to the router, receive the hotmail response from the router on the linux computer and forward it to the windows computer. How do I do that? In essence, switching the Linux laptop between the Windows laptop and the router, to capture network traffic ? Which program is best for capturing/analysing ? Please note that for whatever reason, packet capturing with winpcap on the windows computer doesn't work...

  • How to stop listening on an HTTP::Daemon port in Perl

    - by Trevor
    I have a basic perl HTTP server using HTTP::Daemon. When I stop and start the script, it appears that the port is still being listened on and I get an error message saying that my HTTP::Daemon instance is undefined. If I try to start the script about a minute after it has stopped, it works fine and can bind to the port again. Is there any way to stop listening on the port when the program terminates instead of having to wait for it to timeout? use HTTP::Daemon; use HTTP::Status; my $d = new HTTP::Daemon(LocalAddr => 'localhost', LocalPort => 8000); while (my $c = $d->accept) { while (my $r = $c->get_request) { $c->send_error(RC_FORBIDDEN) } $c->close; undef($c); }

  • How do I dynamically point an interface to a specific class at runtime?

    - by Jon
    As a simple example, I have an xml file with a list of names of classes which actually carry out the work and all implement interface IDoWork with a method Process(). I loop through the items in the xml file. How do I actually dynamically assign the class to the interface from a string name? e.g. var IDoWork = new "DoWorkType1"(); IDoWork.Process(); <work> <item id="DoWorkType1"> </item> <item id="DoWorkType2"> </item> </work> I want to achieve a plugin type architecture, except the plugin isn't at an assembly level only a class level within my program.

  • How do I change my current directory from a python script?

    - by misterloogs
    I'm trying to implement my own version of the 'cd' command that presents the user with a list of hard-coded directories to choose from, and the user has to enter a number corresponding to an entry in the list. The program, named my_cd.py for now, should then effectively 'cd' the user to the chosen directory. Example of how this should work: /some/directory $ my_cd.py 1) ~ 2) /bin/ 3) /usr Enter menu selection, or q to quit: 2 /bin $ Currently, I'm trying to 'cd' using os.chdir('dir'). However, this doesn't work, probably because my_cd.py is kicked off in its own child process. I tried wrapping the call to my_cd.py in a sourced bash script named my_cd.sh: #! /bin/bash function my_cd() { /path/to/my_cd.py } /some/directory $ . my_cd.sh $ my_cd ... shows list of dirs, but doesn't 'cd' in the interactive shell Any ideas on how I can get this to work? Is it possible to change my interactive shell's current directory from a python script?

  • iphone app hangs in AppDelegate (?)

    - by d_CFO
    No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller. In fact, control passes out of the last "}" in applicationDidFinishLaunching. But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there). The last line is, UIApplication _performInitializationWithURL:sourceBundleID:]. I missed a step? I executed a step improperly?

  • Will it use more and more memory if I keep drawing on the UIView?

    This is my drawRect: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 2.0); CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor); CGContextMoveToPoint(context, x1, y1); CGContextAddLineToPoint(context, x2, y2); CGContextStrokePath(context); If I run this code thousand times or more. My UIView will have many lines on that. Will it use more memory than only just one line on it? Er... ...I mean, will the program remember the line I draw or after it draw the lines, it won't have any information in the memory. thz .

  • creating ports and initiating communication between client and server

    - by dave
    what i need is a server that listens to 5060 port , when the client sends data to that port the server should open up another port ( any port after 1250 i believe ) and forward the clients data to that port keeping 5060 idle so it can perform the same function for the next client so basically i need the server to a) open up multiple ports one for each client b) get the voice data from the client and be able to send voice data to that client i m looking into the hardware specs and other such details of the scenario so i dont have time to make such a program myself if theres a code that i can run directly ( both server and client side ) on visual studio .net 2010 that will perform these tasks then that would be extremely helpful thanks alot in advance
