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.
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 trying to detect when my mouse is over a item. I can get it working if its a square shape an stuff.
(LOWORD(lParam) > 133) && (LOWORD(lParam) < 154) && (HIWORD(lParam) > 0) && (HIWORD(lParam) < 21)
but how would i detect if its over the white spot in this image? [URL] ....
i just drew a simple shape i need to detect from more edges but how to do it?.
What is the command to return the position of the mouse on screen in C?
View 8 Replies View RelatedI have a dialog control where I am using a slider control. I have handled the notification messages sent by the slider control. When user clicks on the slider, the slider moves in steps. I want to bring the slider directly to the position where user has clicked the mouse. The slider thumb should directly move to the clicked position instead of in steps.

Place an Image on top of a Button. Move both when the Button is pushed.
Please have a look at this code:
#include <GUI.h>
using namespace Graph_lib;
//------------------------------------------------
class rotation : public Window {
public:
rotation(Point xy, int w, int h, const string& title):
Window(xy,w,h,title),
[Code] ....
The problem is that, it is not possible to define an Image in public/private part of the class rotation. Image needs all arguments to be supplied even when declaring one. (Image is here in Graph.h)
And if I define that Image in the body of main() function, so how to provide access for void rotate() to change its position with the position of button simultaneously.
I have a linear buffer coordinate, i am to print onto a screen coordinate.
Say maxy = 20, maxx = 10, bufferx = 20, y, x,
Buffer coordinates to screen coordinates:
Algorithm: So for each maxx'th of bufferx, y will +1 and x will reset.
Mathematical: y = int bufferx / maxx,
const double averageIncr = int (maxx+1/maxx) - double (maxx+1/maxx);
So the amount of averageIncr in (int bufferx / maxx - float bufferx / maxx)
is the screen x coordinate. Then
(int bufferx / maxx - float bufferx / maxx) / averageIncr = x
Screen coordinates to buffer coordinates:
bufferx, y = 21, x = 10, maxy = 20, maxx = 10,
y * x would be the case if bufferx <= max screen coordinate.
There is no max bufferx.
How to find the transition from screen coordinates to buffer coordinates? Also, if the algorithm within a for loop, or that the mathematical way would be slower or not? I rarely touch floating point stuff.
What I have to do is write a small program in C++ to parse the symbols that are used on 5 different lines of text in each position until position 30 is reached on each line. The goal of the parsing program is to interpret the symbols (characters), if there are any per each position, on the 5 lines of text in order to output the actual data that the group of symbols represents.
My question for is this: Is there anything special from a C++ environment that should go in to something like this outside of using standard stuff like the math associated with the search algorithm that has to happen here? The symbols are located in a file, so I know I have to include "iostream" and a few other headers. But outside of header inclusions and the code necessary to iterate and streamline the search and interpretation process, am I missing anything special that I couldn't otherwise find through simple google searches?
I have a character at a co-ordinate, say (3,4) for example, and I need to get him to (10,15). I would like him to move one block every tick or half a second, so that you can see him moving towards his destination. How to achieve this?
View 3 Replies View RelatedSo, in a program I'm making, I have an idea, that I can print the character background first, then print another layer on top of the background. Can I do that? But I need to be able to place a single character at a certain position, what function does that?

I have 2 points in a cartesian coordinate system, where the first point is always (0,0). Given the second point and a heading in degrees, how would I write an algorithm to determine if the 2nd point is traveling in the general direction of (0,0) ?
For example:
Point a (0,0)
Point b (10,0)
Point b heading = 270 degrees
This would be true this 270 degrees points right and point b is 10 units right of point a. I would probably also want this is be fuzzy somewhat, in that anything from say + or - 30 degrees would also be true, or something like this.
Cam is a pointer to a structure and viewpoint is a vector located within the struct. I am trying to read in from a file the coordinates for the vector. I have also tried &cam->view_point->x as well as &cam.view_point.x and it tells me that I am requesting something not in a struct

How to read pixels from an x,y coordinate using the VGA register values?
byte readVRAMdirect(VGA_Type *VGA, uint_32 start, uint_32 offset) //Used in 256 color mode!
{
if (!VGA->VRAM_size) return 0; //No size!
return VGA->VRAM[SAFEMOD((start*4)+offset,VGA->VRAM_size)]; //The full protected offset!
[code]....
getVRAMScanlineStart(VGA,y) gives the offset register multiplied by 2 (shl 1), multiplied with the current memory address size (byte, word or dword) multiplied by the scanline. 256-color mode is already working. GETBIT gives a bit #(0-7) of a specified byte.

I am drawing in a simple (square) MFC window. I realize that (0,0) starts in the upper left hand corner. I wanted to see how MFC handled drawing of angles, so I use this code:
Code:
double CompassDegreesToRadians(double compassDegrees) {
return((PI / 2.0f) - (compassDegrees * PI / 180.0f));
}
// Make pen
CPen penRed;
penRed.CreatePen(PS_SOLID | PS_COSMETIC, 1, RGB(255, 0, 0));
// Test Angles
[Code] .....
Using this code, and changing the value of angle1 to these values (0, 90, 180, 270) I think MFC uses the coordinate system:
Code:
180 -y
|
|
-x 270---------------- 90 +x
|
|
0 +y
This seems like a strange coordinate system to use. Am I doing something wrong? If this is correct, how can I convert my calculations to this coordinate system? (compass degrees):
Code:
0 +y
|
|
-x 270---------------- 90 +x
|
|
180 -y
I am very much new to C programming. However, I have an assignment regarding linked list.
Problem Statement is: Using linked list store the coordinates of four cartesian points and then find the coordinates having longest distance from its origin.
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;

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) {

this.Controls.Add(objPct);
}
PictureBox objPct = new PictureBox();

View 3 Replies View RelatedI 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?
