i'm a college student studying pc programing, and i was given today a special work and i have to program using miranda... which i've never used it >.< can anyone give me a hand to where to download, how to compile, and a simple tutorial for making a simple program or something?
View 3 Replies View RelatedFirst off, I'm completely new to bash scripting so forgive me if I make any egregious errors. I'm trying to make pop-up reminders for the simple calendar program when. This is what I have so far:
Code:
#!/bin/bash
# set the time format for when
#current="$(date +%I:%M %p)"
current="$(date +%-l%p)"
today=~/.when/today
[Code]....
When I run the script, gxmessage pops up and displays the correct information, but it does so for each line in "~/.when/today" that contains a time that matches the current system time (which would be three pop-ups at 10PM, according to the example). I want it to display the information only once. How can this be accomplished? Is a while loop even the right job for this?

View 14 Replies View RelatedI know very little about MySQL, but I've got some users that need it for testing on a Linux server.So I had set it up a while back, but now I'm running into some small problems.Right now, each user has his own database that I created and can do whatever with it. Each user only sees their own database.I didn't want them to be able to create new databases at all, but they can and when they do anyone can see them.
EDIT(Apparently they can only create databases beginning with the word "test" in the name)
I need to either:
1) Stop them from creating new databases (without affecting their ability to interact with the existing database)
OR
2) Make it so that when they create a database, only they have privileges on it and only they can see it (except mysql root of course).
Anybody know the statement to set these kinds privileges up?
EDIT: pfft... I've a read a bit more and realize that this is an intended part of the installation.
EDIT2
I'd still like to remove the ability to make test databases.
EDIT3:Ok, for reference this is how you prevent users from making and using test databases:
shell> mysql -u root -p
Enter password: (enter root password here)
mysql> DELETE FROM mysql.db WHERE Db LIKE 'test%';
mysql> FLUSH PRIVILEGES;
I am trying to compile the gtk+/gnome project called "Gnome-Vector-Network-Analyzer" which i got it from link : [URL]
In order to install it when i compile it using ./configure , i am unable to "make" it as it throws an error that it can not find the makefile.
the output i get from my terminal is :

Actually I had a folder called Lib, in which I had a few libraries installed and configured.(MPI, PETSc, SLEPc) I accidently deleted (by rm) the contents of that folder.
Then I reinstalled MPI,PETSC,SLEPC using the same tarballs as earlier(thus, the version etc. is the same).
I already had a fortran program with many modules and subroutine files, and the corresponding makefile which used to compile and run fine. But now when I type "make" in the same directory as before, I get this: (shortened, many similar errors)
Code:
Firstly, why is mpif90 compiling my program when I didnt tell it to? In my makefile, I have specified gfortran as my compiler....nowhere have I even mentioned mpif90. Such a thing never used to occur before.
Also, if I rename file_variable.f to file_variable.f90, these errors dissappear (I understand why, but that is not the problem), but a new error comes:
Why is the new MPI installation interfering with make ? I want to go back to how things were before I stupidly broke all installations. The errors themselves are not the problem, the problem is why the new mpi installation is interfering with make.
It seems as if mpif90 has taken over make and gfortran. I suppose I didnt install it correctly, or probably I didnt uninstall the earlier one correctly.
Everything that worked earlier doesnt work suddenly. I use ubuntu 11.04 MPICH2-1.3.2
I'm not really a C++ noob at all, but I am a little rusty at the moment. Still, I CANNOT figure out what is wrong with the following code. I'm using Visual Studio 2010.
Code: #include <iostream>
#include <fstream>
#include <vector>
#include <string>
[Code]....
I THINK I got all of the pertinent code. Anyway, it fails at the *** line. I CANNOT figure out why. If I modify it to be linein.size()-30, it STILL gives me an error. That makes zero sense.
i need to implement a Set class(like in stl) using a vector.Here is my code that doesnt work corectly:

is there any problem that might rise by by having a vector as a member of struct in c++ as follows.ex.

int a;

I am trying to simulate a shell. So what I do is checking of having the parameters from standard input, suc as "/bin/ls -l /home/france/Documents", and then passing them to function execute, which at some point calls execvp(argv[0],argv)The problem is that I don't succeed in using these arguments, while if I call execvp(paramList[0],paramList) it works!!!! Where paramList is exactly what I would put on standard input, but defined statically.
Code:
#include<unistd.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>

I have a vector of octets that needs to be converted to a std string. I'm currently doing it this way:
Code:
stringstream ss;
for (unsigned int i=0; i < data.size(); i++
{
ss << data[i];
}
string s_data = ss.str();
This works, but is there any better way to do it?
Is it not possible to declare a vector inside a C++ class ? Have a look at the following code:
Code:
#include <stdio.h>
#include <iostream>
#include <malloc.h> // malloc
#include <strings.h> // bzero
[code]....
I have two functions:
Quote:
void func1(std::string &s)
{
s.clear();
}

Is there a way to create one template function for both vector and string that would clear them?

im trying to build a simple program for my C programming class, this is the source code
#include <stdio.h>
int main()
{
int length, width, length, height, area, perimeter;
perimeter = width + length + height;
area = width * length + heigth;
[Code]...
i dont see any error (you might)but every time i run it it runs but after it asks me to input for the width i do it but it doesn't take me to the length, it just stays blank until i input another value in the same place for the width, it asks me for 4 inputs in total i don;t know why, and after i run it different times it gives me different values for the perimeter and are. how can I fix this?
make a start up script so that it executes this command: cat /proc/acpi/battery/BAT1/state I managed to execute it writing command to .bashrc, but every time I open terminal it starts like this:

I need this command on start up, so that my battery meter starts working properly. For some reason, if the command is not activated, gnome battery meter is showing that battery is charging even if I am not on AC power. If there is any other way to fix this without making script I would be glad to hear.
I made a simple proxy using netcat and it works great, the idea is to make the server and client communicate through two named pipes, file1, file2.
$ mknod file1 p
$ mknod file2 p
$ nc -l -p 12345 0<file1 1>file2 &
$ nc 192.168.2.118 80 1>file1 0<file2 &
The problem Im facing is that I cant seem to intercept the data going between the client and the server. I want to be able to have the data coming to the server in a variable, manipulate it and send it to the client, and the other way, have the data coming to the client in a variable, manipulate it and send it to the server.
Im running on an embedded device where tee, awk and many other commands are absent. how can I redirect the data to a variable, manipulate it and pass it to the other side, that is the question.

View 14 Replies View RelatedI'm having problems with my php 5.3.3 installation when trying to access remote domains. The problem only happens when the PHP scripts are run via Apache 2.2.15. The problems appear to affect all functions that might access a remote domain (e.g., gethostbyname, file_get_contents, curl, etc.). Basically, pHP scripts can't resolve a remote host when run via apache.
So I thought I might try to reinstall curl (I'm OSX 10.5.8, btw). I ran configure and make fine and then make test reports the following:

how to compile the cpp file by make?
make -w file -> does not work!
make -f file -> does not work!
I just installed a new Ubuntu Studio 11.04 system at home yesterday. It was relatively painless at first but now I'm trying to compile some of the programs that I built the system for and
Code:
./make
simply is not working (returns command not found error). A makefile is present in both of the directories I'm working on.
Code:
man make
works perfectly fine. apt-get install insists that make is present, it also insists that gcc and build-essential are present. Just for the heck of it I reinstalled build-essential but nothing changed. I hesitate to uninstall it or or uninstall make as I have several packages which depend on these and several more which recommend them.
I first got into Linux with Ubuntu Server 10.04 and I remember not being able to compile then but that was because I didn't have gcc or build-essential installed. Once I installed those packages everything was happy. Every google search I perform leads me either to "install build-essentiall / gcc" or to nothing at all. Thoughts on where I can go from here?
I've been trying to figure out how to use make and makefile to compile and link some .cpp/.h. All i seem to find on google says to read the README for the software. But this is my own created c++ project. Im just looking for a simple makefile for my own .cpp/.h files( about 20 total).
I have tried using 2 different makefile "examples" as a template, but neither worked. I am getting error saying "file1.cpp: no newline character at end of file". or something to that degree.
