Visual C++ :: SDI App - Constraint Mouse To Move Only Horizontal Direction If Shift Key Pressed
Apr 23, 2015
In a SDI app, I constraint the mouse to move only an horizontal direction, if "Shift" key is pressed ... here is the code:
Code:
void CTestMouseView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) {
// TODO: Add your message handler code here and/or call default
if(GetKeyState(VK_SHIFT) < 0) {
CRect rect;
GetWindowRect(&rect);
GetCursorPos(&m_point);
[Code] ....
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 ...

How do I tell c++ to move the mouse in place x?
for example, I run a c++ program and the mouse moves to the top left corner of my screen.
How do I go about doing something like that?

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.
I am on Windows 7, 64 bit, using Visual Studio Express 2013 for Windows Desktop
Code:
#include <iostream>
#include <windows.h>
#include <string>
#include <new>
#include <stdio.h>
using namespace std;
INPUT_RECORD ir[128];
[Code] ....

I have the following problem:
My mainframe-window in a MDI-app has a CDialogbar.
Every time the mouse moves over a control in this dialogbar the status bar is updated by a text.
The app craps the text from the resource strings that has the same ID than the dialogbar-control, randomly.
I do not want this. How can I avoid this?

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__
[Code]....

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?

I have a main CWnd class called CMainWnd which is created like this:
Code:
DWORD dwStyle = WS_VISIBLE | WS_BORDER | WS_CLIPCHILDREN ;
...
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), L"", dwStyle, rect, parent, NULL, NULL);
And I draw smaller windows on this main window with a CWnd-dervied class called CClientWnd, which is created like this:
Code:
DWORD dwStyle = WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | WS_BORDER;
...
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), L"", dwStyle, rect, parent, NULL, NULL);
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 pure C based win32 applications. I have drawn line. Now i want to translate that line, move the line whereved user wants to move on screen. Then again I drawn another line, I am drawing multiple lines.
I have created rectangle region for each line and trying to move the line.
When I move the 2nd line over the 1st line on screen the 1st line is getting wiped out. Because I am InvalidateRect() of the rect for the line being moved, so when that rectangle is crossing the other line then the other line is getting removed from the screen.
How can I rectify it. How can I have all the lined being on the screen and moved according to the user's wish. The code should be pure C and win32 no MFC.

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
Code:
if(_controllerState.Gamepad.sThumbRX >= XINPUT_GAMEPAD_RIGHT_THUMB_DEADZONE) {
GetCursorPos(&mousepos);
profile->Buttons[6]->input.type = INPUT_MOUSE;
[Code] .....
I have tried everything to fix it.

I am working on a project in which I use DirectShow to Play / Pause / Stop the video. I am using slider bar to show the progress of the video. As the video starts playing, the slider bar moves in proportion to the video duration. Now when user moves/drags the slider bar to a new position, I want to forward the video in equivalent proportion.
Say if video duration is 50 seconds and max range of the slider bar is set to 100. slider will 2 steps for 1 second of video progress. Now if user drags the slider to 60 while video is playing, I want to increment/forward the video. if user moves the slider backward, video should move backward.
I have done with the slider moving along with the video and when user drags the slider. How to set the new position of the video, so that the video starts playing from that point.

I would like the coded ASCII image to scroll horizontally 3 times and then end with the message:
"Hit Enter to continue or Esc to end"
If Enter is pressed, the program should then continue to scroll another 3 times and then display the same message above.
If Esc is hit then the program loop should stop similar to an escape sequence.
Here is my code that partially accomplishes my objective:
Code:
// Professor.cpp : The entry point for the console application.
#include <iostream>
#include <string>
#include <windows.h>
#include <stdlib.h>

I'm taking a C++ computer science course right now, and one of the questions on my latest assignment is this:
"A partition of an integer n is a way of writing n as a sum of positive integers. For example, for n=7, a partition is 1+1+5. Write a program that finds all the partitions of an integer n using r integers. For example, all the partitions of n=7 using r=3 integers are 1+1+5, 1+2+4, 1+3+3, 2+2+3."
I've been struggling with this problem for a couple days now, and how to do it. I understand I need a recursive function to grab variables, and probably an array or vector to store them, but where to begin.
I've been reading documents on partition generating and the concept still eludes me, and any other questions on here or other programming sites using partitions don't seem to have a constraint on them.

Below, is the program I completed so far. I need to write a C program that reads in a stream of integer values, each representing an (x,y) pair on the cartesian plane. It then says I need to display the distance and direction from one point to the next. I tested it out, and it works.I need to use a conditional statement, and I'm a little confused how to display the direction(right, left, up, or down).I think I need to use an. "If" statement with my first one being something like:
If (y2 = y1) && (x2 > x1)
and I'm not sure what else to put,or if this is wrong. And with y staying the same and x increasing, the direction would be right.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(void)
{
int x1, y1,x2,y2,x3, y3,x4,y4,x5,y5,x6,y6; //x and y coordinates
[Code] ....

i new to c++ programming. i have a program due soon in vector addition. i am to design should be able to add vectors with certain magnitude and direction and give its resultant magnitude and direction (i know how to do this mathematically but programming is not working. the user should be able to select how many vector he/she wants (i don't know how to do this, so i added 3 vectors). here's my work - i did this purely algebraically. it's still incomplete but it compiles. my "if else" statement also doesn't respond correctly.
#include <iostream>
#include <string>
#include <vector>
#define PI 3.14159
#include <math.h>
std::vector<int> v; // declares a vector of integers
using namespace std;

It is technically not a programming question and is more maths oriented. It has to do with game AI and specifically getting the AI to rotate correctly. I am trying to create the base method that handles AI rotation. It will take a target orientation and rotate the entity from it's current orientation to that target orientation.
Let's say we have a Entity that has the orientation of 1.57079 Radians (90 Degrees) and we want to change that Entity's orientation to 0 Radians (0 Degrees). How would one find the correct way to rotate from just them two orientations (IE find the shortest rotation direction from a current orientation to a target orientation)?
As my implementation stands now the Entity rotates just fine I think but always in a clockwise rotation (Because I can't figure out how to determine the best rotation direction). For example using the previous number (1.57079 Radians to 0 Radians) the Entity will rotate all the way around 270 Degrees clockwise instead of rotating just 90 degrees counter-clockwise.
I have thought about possibly projecting vectors a short distance forward from the current orientation and target orientation to figure out the rotation direction but not sure if that is a good way to implement it.

For example: Code: How many rows? 3

How to do that. It's rare that I post without figuring anything out, but I'm just simply not sure. I have a program that prints a triangle in a similar direction, so maybe if I could get some hints as to what to do with that (HINTS, not direct source code) .
Code:

I am having this problem were the user types in a substring to search in the main string and replace it with another string
for example:
