C++ :: Decompress JPEG Images In Android AOKP Source
Nov 17, 2013I am trying to write a c file to decompress jpeg images in android aokp source
Sample from my c code:
...
#include "jpeglib.h"
...
int main() {
struct jpeg_decompress_struct cinfo;
struct jpeg_error_mgr jerr;
cinfo.err = jpeg_std_error(&jerr);
jpeg_create_decompress(&cinfo);
[Code] ....
libjpeg source I am using: [URL] ....
Compiling goes fine, but the linker always fails:
undefined reference to 'jpeg_std_error'
undefined reference to 'jpeg_CreateDecompress'
How can I get it working?
C++ :: Game Design Practice For Accessing Container Of Game Objects
Dec 21, 2014I'm working on my first video game. So far I have a few classes in the game starting with the Game class which includes a list of GameObjects (another class). There are several classes that inherit from GameObjects used to implement things like bullets, explosions, various enemy types, etc.
The game essentially iterates through the list of GameObjects to update/render them. I would like to provide access to the Game's list of GameObjects inside another class (like the Bullet class) so I can put new objects on the list. For example, when a bullet hits, I want to add an explosion to the Game's GameObject list it can be updated/rendered.
How this should be setup? I was considering adding a pointer to the Game or GameObject list to the GameObject class (and methods to access it), but I was wondering if there is a better way to set this up?
C++ :: Program For Calculating Total Price Of Game Station And Game

Jan 27, 2013I'm new in c programming and my requirement is as follows. I make a code for oss mixer and now when new systems, throwing the OSS, and there is no /dev/mixer I want to port my code to alsa but my skills are minimal.
Code:
static int mixer_fd = -1, mixer_src = -1;
static char *devices[] = SOUND_DEVICE_NAMES;
int mixer_init(char *mixer_device, char *mixer_source) {
int i;
mixer_src = -1;
for (i=0;i<SOUND_MIXER_NRDEVICES;i++)
if (strcmp(mixer_source, devices[i]) == 0)
[Code] ....
Coexistance with OSS would be nice, so both could be used depending on users choice. Perhaps: if this first
part of the mixer name is a valid device file, try OSS, otherwise try ALSA?
C# :: How To Multithread Port Scanning App
Jan 24, 2012I'm creating a small port scanning app which use a port range defined by user.My problem with the code is that I find it not efficient enough meaning that it ping very slow, especially when ports are not responding meaning that I must wait for the timeout before continuing to next port.
I want to make this small app threaded. The problem here is that I'm kind of blank of how to implement threading in my program. This is my code which is a method which does the actual checking, the other part of the code is a simple button with for loop for advancing my port number.
Code:
private void ScanPort(IPAddress address, int port) {
using (TcpClient client = new TcpClient() {
IAsyncResult result = client.BeginConnect(address, port, null, null);
if (result.AsyncWaitHandle.WaitOne((int)nudTimeout.Value, false)) txtDisplay.AppendText("Port: " + port + " is open." + Environment.NewLine);
else txtDisplay.AppendText("Port: " + port + " is closed." + Environment.NewLine);
} }
I have read some basic threading tutorial but I just don't know how to implement this piece of code so I can check ports much faster.
C :: Parallel Port Programming - On / Off LED
Sep 9, 2014I try to ON and OFF the LED's via parallel port. I connect the cathode of LED's with pin number 18 that is ground and anode of each LED is connected through a 1K resistor to pin 2 to 8. I write the following programe
Code:
#include <dos.h>
#include <stdio.h>
#include <conio.h>
#define PORTID 0x378
void main(){
outportb(PORTID,0x00);
getch()
}
But when i connect the LEDS to the parallel port all the LEDS are LIT while i also change the 0x00 to 0xff and so on. But no effect on the LED's.

View 1 Replies View RelatedC++ :: Inserting Hex Value And Sending It At Serial Port
Dec 17, 2013I am trying to convert decimal value 1 to 32 to hex value and insert it at 4th pos of char array and send it as hex value at the serial port .
My issue is it is converting to decimal to hex value but when it sends, it treat the converted hex value as char and sends it equivalent hex value.
For example
if decimal =1 then its hex = 1.
so , writebuffer[3] =1
But when we send whole writebuffer through send function, it treat this 1 as char and sends its hex value as 31. how to send its hex value.
unsigned int i=0;
char hex[3];
unsigned char hexunsigned[3];
unsigned int dec;
do {
unsigned char writebuffer[8] ={0x01, 0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};
[Code] ....
The send function is
void serial::send(unsigned char data[], DWORD noOfByte) {
DWORD dwBytesWrite;
WriteFile(serialHandle, data, noOfByte, &dwBytesWrite, NULL);
}

Jun 20, 2014I habe a program, that can send and receive UDP Multicast telegrams. When I open the socket then I bind my multicast group address and the local port to a specified networkcard (our PC has 2 network cards). Now I have a special constellation:
Our PC has 2 network cards. Multicast group 1 shall use card 1 and group shall use card 2. As long as both groups use different local ports it works fine. But when both group want to use the same port number then I can receive and send telegrams only through the first group that was created. For the second one I don't even get a FD_READ event at all.
Code:
SrvAddr.sin_family = AF_INET;
SrvAddr.sin_port = htons( (WORD) nLocalPort );
SrvAddr.sin_addr.s_addr = inet_addr(strOwnIpAddress); // bind multicast group socket to a specified networkcard

Wait for the answer from modem
read serial port
check if command successful (i.e modem sends OK if successful and ERROR if there is an error)

C :: Voltage Range - Write The Value On Serial Port

Now I'd like to write the value of the Input Voltage (which moves in the Range of -10V to + 10V) on the serial port, but i don't know how i should calculate this factor. At the moment, I can only write the value of the A/D Converter Input on the serial, but this is only 0V to 5V...
