I am writing a program for my beginning c++ class. It is supposed to create an invoice in the console window. so far, everything is working perfectly, except for one thing. My invoice comes out looking like this:
696.60 - 27 Adult Meals at $25.80 each.
+ 46.44 - 3 Child Meals at $15.48 each.
--------
743.04 - Total Cost of All Meals (Add the above numbers together)
+ 52.01 - Weekend Surcharge (743.04 x .07)
+143.11 - Tax/Tip ((743.04 + 52.01) x .18)
--------
938.16 - Total Party Cost
- 57.50 - Deposit Received
--------
880.66 - Balance Due
- 32.84 - 3.5% Prompt Payment Discount (938.16 x .035)
--------
847.83 - Balance Due (If Paid Within Ten Days)
The problem is that if I add these numbers on a calculator, I get as result of $847.82, not $847.83. I checked them individually and they are all being rounded properly. If I add them up using the entire decimal value of the calculations, rather than the truncated value, I get $847.83.
So, the question is as follows: In C++, how do I do each calculation, round the answer to 2 decimal places, then use only the rounded number in the next calculation?
Can I make my c++ application to open in a specific sized console window. I want to open my project in n a bigger screen so that all my output is visible. is there any way to do this...
I used the Console's CursorLeft and CursorTop properties to specify the exact areas of the screen where I wanted to print information. I ended up with a 'table' full of data.
Then I used the System.Diagnostics.Trace class and added a TextWriterTraceListener and a ConsoleTraceListener object to its Listeners collection.
Then I replaced all the instances of Console.Write with Trace.Write.
The data displayed as expected on the console. But on the text file the info was printed in the same order the info was outputted to the Console. ie: all the characters used to separate rows lumped together, followed by all the characters used to separate columns lumped together, followed by the actual data that was printed between those characters, all lumped together.
I can see why I ended up with this mess. The TextWriter is oblivious of the fact that the Console's cursor position was arbitrarily modified by the application code before and after each character and piece of data was printed to the Console.
Is there a way I can just grab the text that was printed to the console, ignoring the actual order in which the individual characters were printed, and save it as a string or directly print it to a file exactly as-it-is?
I used to use OutputDebugString, and not using it now because it only allows to strings to be outputted, are there any methods that I can dump virtually anything to the console?
cout << thing << endl;
But what if I am not start running the program from the command prompt?
#include <iostream> #include <windows.h> using namespace System; using namespace std; int refreshDisplay(int , int); const char wHole = '@';
[code]....
count <<" The oblective of the game is for the player to move around a 2 dimensional playing field and capture the star withought falling into a black hole or walking off the edge of the playing field. The controls are W = up S= down A=Left D=Right" <<endl; how implement 3 black hole X characters and 2 wormhole characters on field @ and a star *. all these char has to be randomly generated.
I am trying to do two things that i have an issue with finding on google. the first is im trying to center the main window, but i cant figure out how to do it. secondly i want to make it full screen but the flag for setvideomode doesnt work. is there another way?
I want to make a window tgat stays always on top like that of a cybercafe software. A window that cannot be closed, minimised, deactivated, etc... with wxWidgets.
So far I've tried making a frame window with the wxSTAY_ON_TOP flag. It works, but not to perfection because, when i press the windows button, the start menu interferes with the window(and taskbar too). Also, the task manager, how to deactivate it.
how to make a window in C++? I am trying to make a program that has a boot screen but I want it to be in its own window because it will have it's own pictures in it and text inside too. So not in a terminal but inside a external window.
when i run it , it skips scanf and not allowing user to enter input.tried adding getchar(), fflush but nothing worked for me. //file name : sort_array_of_structure.c
Code:
/*Write a program to accept records of the different states using array of structures. The structure should contain char state, population, literacy rate, and income. Display the state whose literacy rate is highest and whose income is highest.*/
#include <stdio.h> #define M 50 struct state { char name[50]; long int population; float literacyRate; float income; }
There is only one thing I need here. When the paint program is opened I need it to automatically open it maximized. Other than that my code works perfectly for what I'm trying to build.
It has to be maximized so when a friend opens it after I send it to him, it auto maximizes and doesn't start drawing on his desktop.
#include <iostream> #include <Windows.h> using namespace std; int main() { system("start C:/Windows/System32/mspaint.exe"); FreeConsole(); Sleep(1000);
I've encountered a problem, whenever I debug the project, the window shown flickers with the image I'm trying to render and it doesn't respond (shows the loading cursor symbol) also the console window doesn't even open at all, Here's the code:
#include <iostream> #include <SDL.h> #include <SDL_image.h> #include <SDL_mixer.h> using namespace std; int main(int argc, char** argv){ cout<<"HI!!!!"<<endl; system("pause");
This part doesn't work unless I use it with GetForegroundWindow(). But before using it, I have to set it. Is there any way to get window name without setting a foreground window?
unsigned long id = GetCurrentProcessId(); //HANDLE h = GetCurrentProcess(); HWND wind = find_main_window(id); char window_title[256]; GetWindowText(wind, window_title, 256); std::string txtt(window_title);
I've been doing some looking and this example seems like the common way to remove the close button on a wpf window. Other than catching the on_click event or using that example, is there no better way to disable/remove that button?
I want program to make bitmap from my Window. I also want to do add some additional steps which I will try to add later. But now I want to ask you how to fix the code. For some reason when I debug the code (break on line 73 of capture.cpp) there the pointer pBitmap is 0x00000000 . So how to correct the code to successfully capture Window? Here I give the complete codes:
stdafx.h
Code: #pragma once #include "targetver.h" #include <stdio.h>
[Code].....
Feel free to set correct name of Window on line 17 for FindWindow() function.
PS: The code is remake of script to capture screen, which saved the bitmap to file. This is not what I want because I would be content if I could send (or maybe share!) the bitmap to ahk script which will ask my C++ program for the bitmap.
Im new to c#. In c++ I have made a window and painted it with dots and concentric circles, like a radar PPI screen. Trying to do this in c#, I can't find how to draw a single pixel on the window.
Also, what should I be drawing on: the form, panel, picturebox...?
I have created an scientific calculator application and I have a VBS script that runs some of the files. I want to create a C program that runs that VBS script. however, a command window flashes before the application opens. So basically I need a short C (or C++) program that runs a VBS script without a command window popping up. I am on Windows 8 and my compiler is GCC/G++ under cygwin. Here is what I have now that DOES NOT work.
My program accepts strings, places them in a vector and then "bleeps!" out words of my choosing, in this case, "broccoli". But I'm having trouble keeping the output window open even with my Keep_window_open() implementation.
I'm makeing a card game with ncurses. I have all the card and player objects in order but i'm stuck trying to get the gui to work.
I'm using multiple windows for different players deck and pile. Now to the problem: I can get all the windows to show with borders in the console but i can't get any content printed in the windows and I rally can't see why!?
I have been reading the guide on [URL] but I don't get any further on the problem right now.
PS. the complete code incl. Makefile can be found at: github.com/DanBrehmer/cardGame #ifndef GUI_H #define GUI_H #include <ncurses.h>
POINT p; for (int i = 0;; ++i) { HWND hwnd = GetConsoleWindow(); system("cls"); if (ScreenToClient(hwnd, &p)) { //p.x and p.y are now relative to hwnd's client area } cout << p.x << " " << p.y; Sleep(200); }
I'm looking for a function that gives current mouse position(x and y) in that particular console window. I've tried above code but it is not working.
