Visual C++ :: Use Of CListCtrl For Live Data View?
Jul 29, 2013I'm working on an app which monitors user selected data sets from various devices, and I'd like to display the data in a CListCtrl. This would be very convenient, but I'm just a little concerned about (1) just how fast can a CListCtrl be populated, and (2) how can i reduce or eliminate screen flicker. To be specific...
1. There will likely be upwards of 100 rows of data, maybe more (probably 5 or 6 columns), and I'm going to have to refresh it all as quickly as possible, perhaps as fast as once per second. I can play games and only refresh a visible rectangle, but how responsive the control would be, having all that data deleted and refreshed continually?
2. You can see why I'd be worried about screen flicker, and I thought I'd likely have to make two identical overlapped controls so I could double buffer as I would with a graphic animation, switching the visibility of one or another control after its updated to give the appearance of sudden complete updates. BUT... I see there is an extended style you can set called "LVS_EX_DOUBLEBUFFER"

Mar 20, 2014Program to implement Dijkstra's Algorithm. Have Problems storing graph info into linked-list . The input is in the following format
5
1 2 9.0
1 3 12.0
2 4 18.0
2 3 6.0
2 5 20.0
3 5 15.0
0
1 5
The first number is the number of vertexes in the graph. Then next lines up to 0 are the edges of the graph. With the first and second numbers being the vertexes and the third being how far the edge is between them. Trying to read in the data and store the edges into there locations in the List adjacency for that vertex. This example would make a graph with five vertexes with edges from 1 to 2&3. 2 to 4&3&1 etc. It also stores in the opposites ex 2 1 9.0.
When reading it in and printing it back out it seems that it is only storing the last data entered for that vertex. EX. When trying to print out the data read in i only get 1 3 12.0, 2 5 20.0, 3 5 15.0, ( 4 2 18.0, 5 3 15.0 would show up if `if(i<n)` was removed it is there so it does not show duplicate edges).

C/C++ :: Image Overlaid Five Consecutive Times On A Live Video
Nov 30, 2012I am trying to overlay an image on a live video.I have used alpha blending method to overlay image on the video. On overlaying the image, it gets overlayed five times rather than one as expected.
Both frame data and the image data is taken as BYTE* for overlaying and displaying it.
The image used is a bitmap image.
The data (BYTE*) of both the video and the image is overlayed and the resultant is stored back in the variable of the video and den drawn on the picture control of vc++.
The video resolution is 640x480.
The image I m overlaying is 128x128.
The IDE used is visual studio professional.The code is developed using c++.
How do I overlay the bitmap image as a single image on the live video at a specific position.

C :: UDP Application Simulate Packet Loss
Aug 12, 2014have udp server-client application written in C. On the client side packet loss is detected using recvfrom function and sequence numbers of packets. How can I now simulate dropped packet's on the client side, for example if server is sending 1000 packet I want to drop 20% of them? I want to do this in the code, not for example using ip tables or WANEM or something like that. And one more thing, I have few clients and I want that they can dropped different packets, not the same one.
Code:
while(1){
nbytes = recvfrom(socket, buffer, MAX_SIZE, 0, (struct sockaddr *) &srv_addr, &addrlen);
if (nbytes != -1) {
// packet is received
}else{
//packet is not received
}
}
C++ :: Simulate Random Walk In 2 Dimensions
Jan 6, 2015I am writing a piece of code that simulates a random walk in 2 dimensions (an object chooses whether to move up, down, left or right randomly). I would like the program to run the simulation for many objects at the same time. The way i have written it means that for every object i add the code becomes about 40 lines longer. Any method that would simplify the code so that i could have many objects but not pages and pages of code.

C++ :: Program To Simulate Coin Toss
Nov 14, 2013Write a program that simulates coin tossing. For each toss of the coin, the program should print Heads or Tails. Let the program toss the coin 100 times and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip that takes no arguments and returns 0 for tails and 1 for heads. [Note: If the program realistically simulates the coin tossing, then each side of the coin should appear approximately half the time.]

C/C++ :: Can Use Packed Structure To Simulate Memory?
Oct 11, 2013I am trying to simulate memory in C. I want to create a structure in C that will hold a 8bit opcode and a 32bit memory address. This would simulate a 40 bit instruction for my simulator.
I read in an old book that packed structs could be used for this to not waste space. What are the draw backs for using this? I am not worried about wasting space, but just looking for a simple way to access the memory instructions. Below is a sample of the structure that I want to use.
struct memory_area {
unsigned int opcode:8;
unsigned int address:32;
};

C++ :: Simulate Adding Machine - Total / Subtotal
Mar 28, 2013Write a program that simulates an adding machine. When a zero is entered it should print the subtotal of all the numbers entered from the last zero that was entered and reset the subtotal. When two consecutive zeroes are entered it should print the total (not the subtotal) of all the numbers entered and terminate the program. Example:
1
2
3
0
subtotal 6
4
5
-2
0
subtotal 7
8
0
subtotal 8
0
total 21
Be careful this program needs a bit more thought than you might think at first. To get full credit you must make sure it also works for the 0 - 0 case. Example:
0
subtotal 0
0
total 0
The problem is, after I enter the integers and type 0, it shows the subtotal which is what I want; however, when I type more integers and type another 0 to see the subtotal again, it shows the total instead. The subtotal should reset whenever a single 0 is typed and the total should only show when two 0's are inputted simultaneously. Also, after the user enters two 0's simultaneously and views their total, I want the program to exit by saying "press any key to exit." Is there a special name for that to happen? Here is my code:
#include "stdafx.h"
#include <iostream>
using namespace std;
int main() {
int subtotal = 0, total = 0, number = 0;
