I tried to draw two lines with xlib.h in C. If I start this compiled program it show me in most cases a window with two lines as it should be.
But sometimes the two lines are not drawn.If I insert XFlush() before the second XSync() it worked better but not every time.Why?How can I solve the problem?How works the X-Server buffer in detail?

I was doing an exercise on Learning Perl, 3rd edition. (exercise chapter 10 btw) The problem asks to create a program that generates a random number and asks the user to guess. It should tell the user if the guess is lower or higher and exit if the user types either exit or quit. My code is the following:
Code:
#! /usr/bin/perl
$correct = int(1+rand 100);

I need to write a program for time. like i have 2 tasks both minutes and hours.
like this
1st task=5 hours and 30 minutes
2nd task=2hours and 45 minutes
Together they will take 8 hours and 15 minutes.
I need to write a program thats called ADDTIMES to do something like this.
This is what i have so far.
H1=int(input("enter the number of hours:")) etc..
im trying to calculate how much time does my program run, use very simple script
clock_t end, start;
start= clock();
int i;
printf("initial %d
",(int)start);
[Code]....
but it outputs 0 all the time. cant figure out where could be the problem.
i have the example code below, i want to calculate the time taken for a sample program to run. but i keep getting undefined reference error.
#include <sys/time.h>
#include <iostream>
int main(int argc, char **argv) {
struct timeval startTime;
struct timeval endTime;

I am having trouble with encryption/ decryption program. The program goes out and finds the file I want it to, encrypts it into a continuing series of a single repeated negative number, then generally decrypts(or should i say re-encrypts)it into a widely repeated character, different but same results every time.

i am graduate student and my X colleague gave me this Fortran 77 program to run my result files with. She is no longer reachable. I compiled the following program with gfortran, it compiled well but, when i run it, gave me end of file error. My output file (which is the input file for this program (DFILE1) ) has about 78,000 lines of velocities of atoms (Vx, Vy, Vz with 1000 steps.. an example of some of the atom's velocities in the 1st step is given at the end of this program). I will be highly obliged if any one can help me with this.I run this program on opensuse linux 11.3 version /32 bit/i586

I am having trouble writing an Xlib application that displays a window. The most frustrating thing is that I've written applications like this before, and never had any problems. For some reason I cannot get this program to work properly. I'm running KDE and when I launch the program, a "button" for the application will appear on the application panel, however, no window will display. It is possible to right click on the panel button and select the Close item which will successfully close the window.
The following is source code that when built will exhibit the behaviour described above code...
Suppose i have an XID of a window. How can i wrap QPainter to draw on this window? I need something like cairo_xlib_surface_create(), but Qt-based.

I see some developers more interested in openGL. Then what's the difference between xlib and openGL? And which one is more popular used in which industry area?

View 6 Replies View RelatedI'm making a game with the xlib library. What I want to do is to know if the character is standing on a trap or something else.
So far I've solved that using the coordinates but when I draw circles or stuff not shaped like a rectangle it gets to hard to make the game exact.
So what I'm asking for is if there is some kind of function in the xlib that tells you which color a pixel has. Because then it'd be much easier.
I've searched but I haven't been able to find anything good. I found XGetPixel() but that appears to work only with images, maybe I can make my window to be an "image"?
I'm trying to understand how to use colors in Xlib programming. What I think I understand so far is that modern displays use 24 or 32-bit TrueColor. And TrueColor uses three colormaps, one for each primary color, and a single pixel value is composed of three indices.
Now the part i'm confused about is how to get my programs to use a 32-bit TrueColor visual. I thought I could inheret the visual from the root window to get color but it seems no matter what pixel value I use it's either black or white.
I guess my question is, how can I setup my programs so that I can specify a pixel value that is a combination of RGB values to get the color I want?
I come from windows where I simply used RGB(r,g,b) macro to specify colors and never had to worry about depth and colormaps and visuals, so I'm a bit overwhelmed by all of these concepts.
I want to do some experimentation with GUI programming. What mostly interests me is how the toolkits actually work (what are the drawing mechanisms, how it communicates with X, etc.) and how the window managers work. I know it's quite a lot but I don't plan on developing the next best DE/Toolkit/Window Manager, just to play with API, mostly to learn. It seems that there is a shortage of documentation on this topics, I'm trying to find anything for 2 days now with no result.

I'm just wondering what the limits for time are. I have a program that always takes exactly 20 ms, so I assume this is the lowest it can measure, but I want to see if there's some sort of documentation of this.

I am installing in Kubuntu (I cant stand ubuntu anymore) But when i try to use dd to install to a USB, I cant because Ubuntu got rid of the root and when i sudo it, It doesnt seem to work!
Here is the message i get:

When I run Coriander, I receive: Erreur de segmentation (core dumped)
