  • How to show Iplmage format on the GUI of C++ instead of showing it in another windows?

    - by Darren
    I'm trying to display the output image onto the C++ interface instead of creating another window to display the image. For example: cvNameWindow("Window A",0); cvShowImage("Window A", imgA); This will create an window and display the imgA on it. My question is that can i display my imgA onto my C++ interface together with all my other button and textbox. I'm using Borland C++ Builder 6 and OpenCV.

  • error: expected `;' before '{' token - What is the cause?

    - by melee
    Here is my implementation file: using namespace std; #include <iostream> #include <iomanip> #include <string> #include <stack> //line 5 #include "proj05.canvas.h" //----------------Constructor----------------// Canvas::Canvas() //line 10 { Title = ""; Nrow = 0; Ncol = 0; image[][100]; // line 15 position.r = 0; position.c = 0; } //-------------------Paint------------------// line 20 void Canvas::Paint(int R, int C, char Color) { cout << "Paint to be implemented" << endl; } The errors I'm getting are these: proj05.canvas.cpp: In function 'std::istream& operator>>(std::istream&, Canvas&)': proj05.canvas.cpp:11: error: expected `;' before '{' token proj05.canvas.cpp:22: error: a function-definition is not allowed here before '{' token proj05.canvas.cpp:24: error: expected `}' at end of input proj05.canvas.cpp:24: error: expected `}' at end of input These seem like simple syntax errors, but I am not sure what's wrong. Could someone decode these for me? I'd really appreciate it, thanks for your time! EDIT Here is the definition of Canvas in my .h file: #ifndef CANVAS_H #define CANVAS_H #include <iostream> #include <iomanip> #include <string> #include <stack> class Canvas { public: Canvas(); void Paint(int R, int C, char Color); const int Nrow; const int Ncol; string Title; int image[][100]; stack<int> path; struct PixelCoordinates { unsigned int r; unsigned int c; } position; }; #endif

  • Website Reviewing Application/Interface

    - by Eric Di Bari
    I am the technology director at a small nonprofit, and we are in the process of making a new website. We have several proposed mock-ups of different homepage designs, and need to receive input from our board members. Is there an online application/program/framework that will receive and organize user comments? I'm looking for something that will allow commenting while viewing the page, rather than just a message board or wiki.

  • What is the difference between the Control.Enter and Control.GotFocus events?

    - by jameswelle
    This may be a basic question, but I have to admit I've never truly understood what the difference between the Control.Enter and Control.GotFocus events is. http://msdn.microsoft.com/en-us/library/system.windows.forms.control.enter.aspx http://msdn.microsoft.com/en-us/library/system.windows.forms.control.gotfocus.aspx Is it a differentiation between capturing keyboard or mouse input or something else?

  • When should I use print instead of echo in PHP?

    - by Rob
    I understand that echo is slightly faster, and print can be used as a function, but I've been reading an e-book on PHP, and the writer is using print, instead of echo, to output very simple text. print "Your name is $name\n"; So my question is, when would it be appropriate for me to use print as opposed to echo?

  • Best way to manage JSON object via GET and POST in php.

    - by Kucebe
    My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'JSON_Obj' : myJSON_Obj }. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['JSON_Obj'] or $_POST['JSON_Obj']. For example, using file_get_contents("php://input"), i can manage POST requests in that way, but in GET format it doesn't work. Any suggestions?

  • Disable JPanel with visual effect

    - by Ryan
    I'm looking for a good way to disable a JPanel. I'm using a MVC design for a Java Swing GUI. I want the JPanel to be disabled while the model is processing stuff. I've tried setEnabled(false). That disables user input on the JPanel, but I'd like it to be grayed out to add a more visual effect. Thanks in advance!

  • Detecting jQuery UI autocomplete

    - by Soldarnal
    How can I detect whether or not an input box is currently a jQuery UI autocomplete? There doesn't seem to be a native method for this, but I'm hoping there is something simple like this: if ($("#q").autocomplete) { //Do something } That conditional, however, seems to always return true.

  • Trouble echoing data - data being converted to 0

    - by Haraldo
    Hi, I feel this is something to do with my httpd setup for apache. I'm using mod_rewrite if that helps but I think that only effects the url. It seems when I output some data such as: $sMessage = 'Error'; echo $sMessage; It works fine but when I do this: $sMessage = 'Error'; echo ''+$sMessage+''; It returns 0. Very odd!

    - by Mark Lubin
    For the CS majors out there what were the hardest CS classes or concepts that you learned in your undergraduate schooling? Did you find once you learned the basics,(data structs, OOP fundamentals, discrete math, pointers, recursion, etc) the rest followed naturally or did you hit a wall at any point in your higher classes like OS'es and Compilers? Thanks for the input!
