  • Program to call other programs

    - by Evil
    hello. I am writing a program that will solve a type of min. spanning tree problem. i have 2 different algorithms that I've gotten working in two separate .cpp files i've named kruskels.cpp and prims.cpp. my question is this: each file takes the following command line to run it . time ./FILENAME INPUTFILE FACTOR i would like to make a program that, depending on what inputfile is entered, will run either kruskels.cpp or prims.cpp. how can i do this? this program must pass those command line arguments to kruskels or prims. each file (kruskels.cpp and prims.cpp) are designed to be run using those command line arugments (so they take in INPUTFILE and FACTOR as variables to do file io). this should be for c++.

  • Jquery Cycle Lite plugin unable to see images that have been loaded by an AJAX call

    - by William Macdonald
    Hi, I am having problems using the jquery cycle lite plugin on some images that are added via AJAX. Here is the jquery code: $(function() { resizeWindow(); $(window).bind("resize", resizeWindow); $("#assignment-nav").accordion({ header: "h3", autoHeight: false }); $(".project").click(function() { // get the HTML and load into div $('.image-holder').empty(); var justTheNumber = $(this).attr('id').replace('project-',''); $.get("get_project_images.php", {project_id:justTheNumber}, function(data){ $('.image-holder').append(data); } ); $(".image-holder").cycle({ // Cycle plugin prev: '#prev', next: '#next', timeout: 0, speed: 250 }) }); }); My code works fine in that the IMG tags are loaded and the first image of the slide show is displayed. However the prev/next buttons don't work. When I load the images via static HTML the slideshow prev/next links works fine. (I just copied and pasted the generated HTML.) I understand I need to use something like .bind or .live to make the Cycle plugin 'see' the new images. I have tried everything I can think of but I can't make it work. What am I doing wrong ?

  • Cannot select radio button that was added by JavaScript in watir

    - by karlthorwald
    This was added to the page later with jQuery: <input name="pdfRadio" id="pdfRadioNo0" value="0" type="radio"> This code: radio_id = "pdfRadioNo0" ie.radio(:id, radio_id).set() does not set it but returns an error message: Watir::Exception::UnknownObjectException: Unable to locate element, using {:id=>"pdfRadioNo0"} Does watir also find radio butons that were added later? This is windows 32bit XP SP 3 , IE 7, watir 1.6.5, ruby 1.8.6

  • gdb: SIGTRAP on std::string::c_str() call

    - by sheepsimulator
    So I've been trying to use gdb to return the value of a string I have by calling > print <member variable name>.c_str() But everytime I do so, I get this: Program received signal SIGTRAP, Trace/breakpoint trap. <some address> in std::string::c_str() from /usr/lib/libstdc++.so.6 GDB remains in the frame where the signal was received. To change this behavior use "set unwindonsignal on" Evaluation of the expression containing the function (std::string::c_str() const) will be abandoned. Two questions: Why/how is the standard library throwing SIGTRAP? I checked basic_string.h and c_str() is defined as: const _CharT* c_str() const { return _M_data(); } I don't see any SIGTRAP-throwing here... is there a way to get around this SIGTRAP? How can I read the text value of the std::string out (without getting some crazy extension library) in gdb?

  • How to call PHP proxy script from JQuery

    - by recipriversexclusion
    I'm trying to get cross-domain Ajax to work. I downloaded a PHP proxy script from the Yahoo Developer site, ran it from command line and verified that it receives the XML from the server with a GET request. Now, I'm trying to connect to the PHP script within JS with no results. I have the following: <script type="text/javascript" src="jquery-1.4.2.js"></script> <script type="text/javascript"> $.ajax({ type:"GET", url:"proxy.php", dataType:"html", success:function(msg){ alert(msg); } }); </script> What this does, though, is to output the source of the PHP script in the alert box, not the XML! Where am I going wrong?

  • Exception calling remote SOAP call from thread

    - by Duncan
    This is an extension / next step of this question I asked a few minutes ago. I've a Delphi application with a main form and a thread. Every X seconds the thread makes a web services request for a remote object. It then posts back to the main form which handles updating the UI with the new information. I was previously using a TTimer object in my thread, and when the TTimer callback function ran, it ran in the context of the main thread (but the remote web services request did work). This rather defeated the purpose of the separate thread, and so I now have a simple loop and sleep routine in my thread's Execute function. The problem is, an exception is thrown when returning from GetIMySOAPService(). procedure TPollingThread.Execute; var SystemStatus : TCWRSystemStatus; begin while not Terminated do begin sleep(5000); try SystemStatus := GetIMySOAPService().GetSystemStatus; PostMessage( ParentHandle, Integer(apiSystemStatus), Integer(SystemStatus), 0 ); SystemStatus.DataContext := nil; LParam(SystemStatus) := 0; except end; end; end; Can anyone advise as to why this exception is being thrown when calling this function from the thread? I'm sure I'm overlooking something fundamental and simple. Thanks, Duncan

  • Call an haskell function in .net

    - by SuperBloup
    Hi, I want to use an Haskell function with the following type :: string -> string from a C# programm. I want to use hs-dotnet to bridge both worlds, the author claim that it's possible, but provide no sample of this case. The only samples provided are the one to use .net from haskell. Does anyone got a sample of this use, or got an idea how to use it? (I used reflector on the bridging assembly but didn't understood a thing)

  • Passing expression as a parameter in Call by reference

    - by darkie15
    All, When we are passing an expression as a parameter, how does the evaluation occur? Here is a small example. This is just a pseudocode kind of example: f (x,y) { y = y+1; x = x+y; } main() { a = 2; b = 2; f(a+b, a) print a; } When accessing variable x in f, does it access the address of the temp variable which contains the result of a+b or will it access the individual addresses of a and b and then evaluate the value of a+b Please help. Regards, darkie15

  • Executing certain code for every method call in C++

    - by Luís Guilherme
    I have a C++ class I want to inspect. So, I would like to all methods print their parameters and the return, just before getting out. The latter looks somewhat easy. If I do return() for everything, a macro #define return(a) cout << (a) << endl; return (a) would do it (might be wrong) if I padronize all returns to parenthesized (or whatever this may be called). If I want to take this out, just comment out the define. However, printing inputs seems more difficult. Is there a way I can do it, using C++ structures or with a workaroud hack?

  • call flex initComplete at a specific time

    - by dubbeat
    Hi, Below is the overriden on complete function for a preloader in Flex. private function initComplete(e:Event):void { //dispatchEvent(new Event(Event.COMPLETE)); cp.status.text="Configuring... Please Wait"; } What I want to do is when the app has finsihed loading I want to change the preloaders text to "configuring". Then I want to go and do a bunch of setup stuff in my code. Once I've done all the setup I wanted how can I get the Preloader to dispatch its Event.complete from else where in my code? I tried Application.application.preloader but it comes up null. So I guess my question really is how to access a preloader from anywhere in my application. Would a better approach be to have all setup classes as members of my preloader class?

  • Suppressing the language select button iPhone

    - by AWinter
    I'm working on an application now that contains an account register section. One field with secureTextEntry = NO (for registering only). The idea is this make registration faster and hopefully increases the number of signups. It's simple enough for me to just place a regular UITextField but if the user has any additional language keyboards then it's possible for the user to enter non-password friendly characters. Unlike in when secureTextEntry = YES. I know I can do textField.keyboardType = UIKeyboardTypeASCIICapable to get the text field to display the ASCII keyboard first, but the user will still have the keyboard switch button which will allow them to get to undesirable characters. Is there a simple method for suppressing the international button or forcing ASCII only keyboard with no international button? [EDIT] Another perhaps better option might be to suppress multi byte keyboards or even to display the text in the case that secureTextEntry = YES any ideas here? [EDIT AGAIN] I've decided it's a really bad idea to suppress the international button as non-multibyte characters should all be allowed.

Does anyone can help me? Thanks

  • Cannot call external javascript function from SITE.MASTER

    - by WOPR
    I have a Site.Master in my ASP.NET project which defines a HEAD section as follows <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title id="MasterTitle">MyApp</title> <link rel="icon" href="Content/icon.ico" type="image/x-icon" /> <link href="Content/mycss.css" rel="stylesheet" type="text/css" /> <script src="Content/mycode.js" type="text/javascript"></script> </head> In the mycode.js file, I have a function called GetSels(); function GetSels() { //do stuff } If the GetSels function is defined in Site.Master, GetSels is callable. If it's in mycode.js, it's not. Every code example I've see seems to says this should work. What am I doing wrong?

  • Call Python From PHP And Get Return Code

    - by seaboy
    Hello everyone, I am calling a python script from PHP. The python program has to return some value according to the arguments passed to it. Here is a sample python program, which will give you a basic idea of what i am doing currently: #!/usr/bin/python import sys #get the arguments passed argList = sys.argv #Not enough arguments. Exit with a value of 1. if len(argList) < 3: #Return with a value of 1. sys.exit(1) arg1 = argList[1] arg2 = argList[2] #Check arguments. Exit with the appropriate value. if len(arg1) > 255: #Exit with a value of 4. sys.exit(4) if len(arg2) < 2: #Exit with a value of 8. sys.exit(8) #Do further coding using the arguments------ #If program works successfully, exit with a value of 0 As you can see from the above code, my basic aim is for the python program to return some values (0,1,4,8 etc) depending on the arguments. And then the calling PHP program to access these returned values and do the appropriate operation. Currently i have used "sys.exit(n)", for that purpose. Am i right in using sys.exit, or do I need to use something else? And also what method exists in PHP so that I can access the return code from python? Sorry for the long question, but hopefully it will help in you understanding my dilemma Thanks a ton

  • How to call a javascript function from one frame to another in Chrome/Webkit

    - by bambax
    I have developped an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in FF but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in FF 3.6 and Chrome 3 but in Chrome 5 it throws the above error...
