Visual C++ :: Mouse Input Coordinates Not Being Read
Jan 14, 2015
When I click the mouse, the program doesn't seem to record the coordinates. So the if statements are never executed. 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.

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.

I have been working on a program to read in a tab deliminated text file of xyz coordinates of atoms/particles and store the values in three seperate arrays. This is my code so far:
Code:
#include<stdio.h> #include<stdlib.h> void fileinput(FILE *ifp) { int N, column, atom; int c; column = 1;
[Code]...
Supposedly this should assign the values in the text file to the cooresponding arrays but when I run the code on a simple test file all I get is:
Code:
$ ./input.o -i ./test.txt Atom one coodinates x 0.000000, y 0.000000, and z 0.000000 Where test.txt is: Code: 1.0000 2.000 1.5 3.0000 5.000 1.4 4.0000 3.000 1.3
I am doing c++ program to read coordinates from text file into double linked list. Everything seems to work perfectly but it stores only 298 items in linked list. Im not sure if my code is wrong or I missed something. On the debugger length of list is over a 1000 but like I said it print outs only 298.
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 have a dialog app with two separate static controls. Both controls have been subclassed from CStatic derived class to implement drag and drop and double clicking. The class works just fine, but I cannot figure out which of the controls is being double clicked or dragged and dropped onto because I only have the code below operating. I need some method in the derived class to determine which control is being manipulated.
Code: // header file #pragma once #ifndef __AFXWIN_H__
I am currently starting to attempt to make a program that can move my cursor to certain colors on my monitor. The problem is this seems like it will be 10x harder than I first thought.
For a ribbon bar with edit controls (CMFCRibbonEdit) I want to handle the mouse scroll events for the edit controls. That is, when the user clicks and then scrolls on the edit it will navigate a predefined list of strings. I want to capture the scroll event in order to update the edit text step by step.
This kind of behavior is implemented by the Spin Edit; I don't want to use the spin edit control since it only uses a list of integers and the spin buttons are too small.
Is there a way to catch the mouse scroll event for the CMFCRibbonEdit control? How to approach message handling for the ribbon (other messages than the COMMAND allowed by the ribbon designer). I'm using VS2010 on Windows 7 and the ribbon was designed with the ribbon designer?
In the main window I draw lots of background stuff using a memoryDC and BitBlt(). In the child window, I actually am not drawing anything, I just created it to have events like mouse over, etc. In the child window when the mouse is over the window I bring up a pop-up window. This works unless my mouse is over any parts where something is drawn in the main window, then the popup just flickers constantly. Why is the main window affecting my mouse over events if I am not handling any such events for it?
I 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.
I am writing a program to map keyboard and mouse to an xbox 360 controller with win32 and xinput. I have everything going fine but when im trying to control the mouse with the thumbsticks I get problems with the movement if my program has the focus it moves fine but when I put another window in focus the movement is over sensitive here is the code I am using
Nothing complicated, and it works well ... except one thing: when I press the shift key and the mouse is moving by SetCursorPos, is moving pretty slow ... why ? I can not figure out why ! For testing, I attached the test project ...
It outputs whole lot of nonsense snippet: 8?/usr/lib/libSystem.B.dylib&X)`!jH??H???H?H?u?????? H?H???H?H?9u?H??<????????UH??H??H?}?H?H???wH??]??? UH??H?? ?}?H?u??E???H??H???l?H??E???????H??H????????? ????M?M??u?H?gH????E??E?E?E?H?? ]ÐUH??????lj??
I am trying to write a program which reads a string and prints the reversal of that string. My main problem, is the fact that I need to type my input to be reverse twice, and only reads at the second time.
Here follows my code :
#include <stdio.h> #define N 100 int main(){ char array[N], *pointer; int x = 0; printf("Enter a message: ");
Code: #include <stdio.h> int main(void) { char c; int i=1; while (scanf("%c", &c)==1) printf("loop sequence %i: %c(%i)
[Code] ......
Done it seems a "carriage return" serves two purposes here, one is to signal the program to read in the character typed in before the "carriage return", another serves as a second character typed, how can i do this cleanly, that is without having to use a "carriage return" as the second character to signal "I've typed in the first character already".
I'm new to C/C++. I am attemping to use fgets and sscanf to read a line of input, and confirm it is a positive number.My code works great, except for the case of a negative number. When I enter a negative number, my while loop seems to run infinitely, with stdin providng the same input over and over again.
So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1520 1730 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1730 1730 [1730==1730] Enter two times in military format (e.g., 1730 1520): 1760 1520 1760: [INVALID TIME 1] Enter two times in military format (e.g., 1730 1520): twelve 2 [INVALID NUMERIC INPUT]
It's a tic-tac-toe program. I haven't finished doing everything I need to for the project, I'm just trying to get certain parts working as I go.
Anyway, my problem: The program will print the board and ask the first player which square they want to mark. Then it will print the updated board, print the question for the second player to input their square choice but not actually stop to let the user enter anything. Instead it prints the board again and then prints the question for player one again -- this time stopping to let them type in their choice.
Here's my code:
#include <stdio.h> // Function prototypes void printBoard(char board[3][3]); int main() { int quit = 0; // Loop so game continues until player quits
[Code] .....
And it looks like this when I run it, as an example:
I'm very new to c programming and I have some background in C# and java. I am supposed to read a string from input then determine in that string, which character is the largest, i.e. I think b>e and e>z, e.t.c. If the string is empty I should return ' '.
I haven't done any programming in C before and I don't know how to handle strings and characters in C.
The problem states that i need to accept any pin number between "00000" and "99999". I need to read the PIN the user enters as an integer. The problem is that if the PIN is read as an integer, the PIN "01111" will be "1111" which is invalid and the pin "00001" would be read as "1" which is also invalid. How would I go about fixing this problem for PIN numbers that start with a "0"? Again I cannot read the PIN as a char array or string.
