C :: Calculator Using Mouse With A Bug While Dragging
Mar 6, 2015
I have an assignment to do a calculator in C, wich will work by clicking the numbers with the mouse, however i have a bug that when i hold the mouse and dragg it, it assumes that I'm clicking multiple times, also, when I click in an empty space the program creates a blank space on the calculator screen.
Code:
#include <stdio.h>
#include <conio.h>
#include <math.h>
#include "..MouseHandler.h" // ajustar o caminho ao seu projecto
#include "..calcSkinLib.h" // ajustar o caminho ao seu projecto
#define PI = 3.1415;
[code]....

i have developed an application in which i have icons in left side pane of application which can be dragged and dropped in client screen. Application is working fine with all the resolution except 1920x1080.
when setting the resolution to 1920x1080 while dragging icons to client area, icon is not attach to mouse pointer. instead there is a gap between the mouse pointer and the icon. i wrote code to identify the screen resolution but it does not seem to recognize 1920x1080 resolution. below code is giving incorrect resolution for 1920x1080 setting.
RECT actualDesktop;
GetClientRect(GetDesktopWindow(),&actualDesktop);
value of 'actualDesktop' variable is {top=0 bottom=783 left=0 right=1536} which is incorrect. according to current resolution size value should be {top=0 bottom=1080 left=0 right=1920}. Due to this, all the icons while dragging are adjusting according to incorrect resolution setting.
how to identify the issue and if there is any limitation with respect to screen resolution in VC++ 6.0 with windows 8 environment.
I am getting same issue when compiling in VS2012 in windows 8. Code does not seem to recognize 1920x1080 resolution setting and downgrading my application look and feel by setting it to lower resolution.

is there a difference when creating a graphic user interface dragging and dropping controls in the form and coding on source code, difference in a sense that the code will appear differently if the control is dragged then the code appears automatically on the source code as compared to typing it on source code?

i would like to add a image box to my application which shows a view/picture where ever my mouse is pointing. something like windows magnifier but it must not zoom in anything it must just display in picture box what your pointer is on.
So basically you have a picture box 504, 86 okay in a form when you move your cursor of mouse around desktop what ever you look at it will be visible inside picture box.
This is what i have so far.
private void MainForm_Load(object sender, EventArgs e) {
objPct.Visible = false;
this.Controls.Add(objPct);
}
PictureBox objPct = new PictureBox();
[code].....

I have a game that I'm trying to create but I don't really know how to handle mouse motions yet. I have read the LazyFoo.net lesson 9. And I have too searched around on Google but haven't find any good article for what I want to do
But what I want is to check if the mouse is OVER the START button of the game and if the user has pressed the LEFT mouse button the game should START.
This works when I am hovering over the area there I want the mouse to do something:
Code:
else if (event.type == SDL_MOUSEMOTION)
{
if (event.motion.x == 0)
{
quit = true;
}
}
I do not know how to check this. The START and QUIT button is in the middle of the screen and I don't know how to position the mouse there either.

I am using SDL 2.0. But I don't know how to handle mouse input. Do you think you can explain of how to do that? Or give me a link that explains that really great?
I know how to handle a mouse button that presses down for a sec.
Code:
if (event.type == SDL_MOUSEBUTTONDOWN){
if (event.button.button == SDL_BUTTON_LEFT){
// Do something . . .
}
}
But not how to handle the mouse input of what the mouse is hovering over and that.
Like in a start menu of a game. I want a button for example to appear blue when I hover over it and when I click on it. It should start the game for example.

I want to track the mouse movement. I know that GTk+ provides some powerful libraries for creating GUI, that will, among other things, enable me to write handlers for mouse movement events, but I'm looking for a simpler, more compact capabilities for now.
Is there a low level C library that will enable me to interface with the mouse?

After searching on stackoverflow I got this
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.

Essentially the problem is that when I click the mouse, the program doesn't seem to record the coordinates. So the if statements are never executed. The problem could also be with the if statements, I'm not sure.
One thing I noticed was that when the do while loop is running and the left mouse button is not pressed then X and Y of dwMousePosition are both 0. But then if I press the left mouse button then the coordinates become x = 1 and y = 0.
NOTE I'm on Windows 7, 64 bit, using Visual Studio Express 2013 for Windows Desktop
#include <iostream>
#include <windows.h>
#include <string>
#include <new>
#include <stdio.h>
using namespace std;
INPUT_RECORD ir[128];
DWORD nRead;

I have set a variable as follows:
Point clickLocation = new Point(0, 0);
But when I got to use
clickLocation = Cursor.Position;
It gives me an error of position does not exist? Does WPF not support this way?

I am developing an application which can be used for digitize a geographical map through GUI and mouse interaction. Well, here are the list of objects that need to be created using mouse clicks.
1) Points
2) Polyline
3) Polygon
4) Rectangle/Square
5) Ellipse/Circle
6) Text
What will be the best design which can be used to store the data(objects) more efficiently? So that both accessing objects and rendering them will be easier and faster? I have started with Composite Design pattern to store the objects and Visitor Design pattern to render these objects.
[Code] .....
But everytime rendering is done sequentially. Will not this take more time if the number of objects increases?

I am trying to detect keys pressed on a keyboard and mouse on both, Windows and Linux but I am unsure what would be the best practice way to do so. Will I have to detect the keys for each platform individually? Would you make use of an event listener? What's the best way to detect the input-devices?

I'm trying to create a program which can pan by keep clicking and move the mouse
1. First, I create a class that inherited from the UserControl Class
public partial class CanvasCtrl : UserControl
protected void OnMiddleMouseDown(object sender, MouseEventArgs e) {
if (e.Button == MouseButtons.Middle) {
[Code] ....
2, Second, I create the void in that class too, and write the code to get it to catch the event
public void MainMouseAction() {
this.MouseClick += new MouseEventHandler(OnMiddleMouseDown);
}
It not work, how to solve this out ?

I am trying to build a WinForm application that will allow you to load an image into a picturebox and then draw multiple rectangles (empty or translucent) to kind of highlight areas. I want all the rectangles to stay on the image (i can take care of a clear method later). The code below has the latest two attempts I've tried. One is all commented out and the other is not. Both will load the image just fine but neither will allow me to draw/select rectangles on the image.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
