C/C++ :: Draw Sprite On The Window Of Third Party Application
May 8, 2014
How can I draw a sprite/graphic on the window of an third party application? E.g. I want to draw a graphic beneath each tab of Firefox for additional information. The position of the sprite needs to be relativ to the position of firefox, so if you move firefox, the sprite moves with it.
The solution needs to work on mac and pc. So I'll use a crossplatform framework like c++ boost or something.
Of course I can get the position and then just redraw it. But what's the best way to draw it?
Just found a tool which does what I need. Basically a HUD like this: [URL] .... The boxes with the numbers are what I need.

I have a question about SDL and drawing sprites (SDL surfaces). My idea is that the user can create a wall of separate sprites by create one sprite each time in the current mouseX and mouseY position, when the user push down the e-key. The problem is that I have no idea how I could draw the same sprite multiple times without to delete the previous one.

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...?

Is there any way that I can call a function/receive an event whenever an external window (not any of my forms) repaints/draws?
If you create a GDI+ graphics object and give it the HWND of another window that refreshes a lot like a web browser, anything with animated graphics, your draws and the windows draws are out of sync which creates an intense flicker effect.
Googling this issue only brings up results for handling when my own form repaints...
My idea is that I could just redraw my GDI stuff whenever the form redraws, this is indeed possible?

I am developing a MDI application that will contain a RibbonBar and a Properties Pane window. The MDI documents are not tabbed. I am finding that when I try to move the client window around, it gets clipped by the RibbonBar and the Properties Pane window (shown in image). I know the client window cannot go outside the client area, but can the client window be on top of the ribbon bar and the properties pane window?
I am using VStudio 2008.

I'm trying to make colors transparent in c++ using a 3rd party library. I've successful made my background transparent but I feel I'm cheating by not understanding how I entered the value.
"0xff, 0xff, 0xff" is the color white but i'm not sure how it's the color white like with RGB values.

I am trying to add in a few 3rd party libraries to an existing project solution. I have no source code or knowledge on how the libraries were built (i.e. what run-time library was used). I have recieved the following errors and warnings:
1>CAPS_LIB.lib(PCEfunc.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance
1>libcmt.lib(getenv.obj) : error LNK2005: _getenv_s already defined in MSVCRT.lib(MSVCR90.dll) ***There are multiple of these errors
1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
1>MSVCRT.lib(cinitexe.obj) : warning LNK4098: defaultlib 'libcmt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library
1>libcmt.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
1>C:Program Files (x86)BCI 2000 v3progRelWithDebInfo..CAPSVRInterface.exe : fatal error LNK1120: 1 unresolved externals
CAPS_LIB.lib is one of the libraries I am trying to add in and it seems to be the one causing the problem. I believe I have added in all three libraries into the project solution correctly, but I can't seem to find a solution to these errors.

I'm making my view follow around my players ship, so it is always in the center, however at any angle other than 0/90/180/270 the player sprite starts shaking, more so when speed is increased and when the angle is closer to 45/135/225/315
I'm using SFML2, I would take a screenshot but it only captures one frame, which doesn't actually show it shaking.
void ViewFollowPlayer(sf::View& View, sf::RenderWindow& Window, double Delta)
{
double pSpeed = Player.getSpeed();

So this is my first try animating on my own, without a reference right in front of me. It's not working, I did check some of the projects I've made in the past, but for one those were done with Allegro, and really it should be able to move over to SFML quite easily, but it's not. It does display on the window in the correct place, but there are 3 pictures in the file and I want it to cycle through them, but it shows all three at the same time, and it only works once. if I press space a second time, only one of the pictures shows up, and it doesn't cycle at all. Here is my .cpp file :
#include "headers.h"
#include "SwordSprite.h"
int top = 0;
int left = 88;
int right = 132;
int bottom = 35;
SwordSprite::SwordSprite() {
[Code] .....

how I want my sprite movement to work: if my sprite is faced upwards and i press W, it will move up. If my sprite is faced to the right and i press W, it will go right. etc. // It doesn't work like that right now and how to do it.The sprite's rotation works fine.
if(sf::Keyboard::isKeyPressed(sf::Keyboard::Q)) {
playerSprite.rotate(-0.08 * dt);
} else if(sf::Keyboard::isKeyPressed(sf::Keyboard::E)) {
playerSprite.rotate(0.08 * dt);
[code]....
My question is how do I move the character depending on the rotation?
Also, you might see the "if(havePlayersCollided == false) {playerSprite.move(yadiyada)}" . yes i dont need the haveplayerscollided function because it doesnt work the way I want it to. I might make a thread for it in the future, but right now I need to get the rotation movement fixed before I move onto the collision detection between players.

So I have a small game I'm making using OOP principles, I know it's a little bit of overkill but it's just for educational purposes. I have a sprite character that can be moved around with no problems, but I made a sword for him as a separate sprite that doesn't follow him. The sword sprite is supposed to cover his arm and his body as it swings, but it just stays in the upper left corner.
I messed around with the initialization of the sword in the main.cpp and I changed in sword.cpp and sword.h and it still is showing up in the same place. I even looked at the GetX() and GetY() statements I made and they seemed to work fine and when I debugged it, the variable values showed up correctly, but the sword doesn't move.

I'm making a 2D rpg game, but I have some problem with the sprite movement. The sprite movement feels choppy. That's because I move the sprite 5 pixels per seconds. I now that I need somthing that have to do with SDL_getTicks and deltatime, but I dont know how to use/implement it.
Here is a little part of my code:
float spriteDstY;
float spriteDstX;
float speed = 5;
while(SDL_PollEvent(&event)!= 0) {
if (event.type == SDL_QUIT)
[Code] ....

I'm trying to get smooth sprite movement in SDL by using delta time. The way I'm calculating it is
long last = 0;
float deltaTime = 0.0;
...
long now = SDL_GetTicks();
//deltatime is in seconds
if (now > last) {
deltaTime = ((float)(now - last)) / 1000;
last = now;
}
And I'm updating the sprite like this:
virtual void update(float deltaTime) {
float dx = 100*deltaTime;
transform->position.x += dx;
}
But the movement is still noticeably jerky. Also, if I'm correct, my sprite should move 100 pixels to the right every second using this method, so it should take the sprite 8 seconds to reach the end of my window, since it's 800 pixels wide, but it takes it way longer than that. In other words the delta time I'm calculating can't be correct. Am I doing something horribly wrong? I'm guessing it has something to do with rounding, but I'm not sure.

I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?

I am fairly new to c++, and I want to be able to draw a polygon. When I have searched for how to draw one, the only thing i can find is scripts doing things like this:

I doubt that c++ is that primitive, and I'm looking for something like the c++ equivalent of this python script:
Syntax: draw.polygon((20,20)(30,30)(50,30)(20,40)(20,20), fill(green))

I'm trying to create a grid using the following characters: !, @, #, $, &.
It's an 8 x 8 grid, and should contain the characters in no particular order (trying to create a Bejeweled-like game).
I already defined the width and length to be 8, so:
#define WIDTH 8
#define LENGTH 8
Code:
void makegrid(char grid[])
{
int j;
int k;
for ( j = -1; j < LENGTH; j++ )
{
for ( k = -1; k < WIDTH; k++ )
{
/* I don't know what to type here anymore :( */
}
} }

This is my first time using opengl and I am experimenting with adding/drawing polygons/points/etc. on top of a PPM image. The image is already loaded when the application runs. My attempt to draw a square is from lines 30 - 35. The program runs but the square is not present. Just the image.
#include<windows.h>
#include <stdio.h>
#include <stdlib.h>
#include<Gl/gl.h>
#include<GL/glut.h>
int n;
int m;
int *image;

I want to write a function called DrawLineSegments.This function must change the color of lines at every corner where the corner angle is greater than 60 deg (Assume that there is a function called checkangle). The color sequence must be black, red, green, blue, and repeat this sequence after the fourth color.
