how to generate excel charts from C, or if it's possible at all? For example, if I had 2 arrays that I wanted to export to excel and graph against each other. I know how to export it to a csv file, that's no problem, but I have no idea where to start with generating a graph of the data. I can't seem to find any examples anywhere. Just a simple example to show you what I mean: Code:
char arr1[] = {'a','b','c'};
int arr2[] = {10,20,30};

Unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system. A code snippet/hint for the pop-up window then?

Does OS (specifically, linux) place any restrictions on user programs entering protected mode. If it does not, do we just have an assembly language program which changed the mode, followed by the C code... I'm just trying to understand how things work at the lowest level. So I'm trying to write few snippets to test my understanding.

I am running some muti-threaded code that uses a lot of memory (~6GB). I have it compiled on a cluster that uses Xeon 5160 quad core CPUs with 4MB cache/core, 8GB of RAM and kernel 2.6.18 (x86_64) and I have also the same code compiled on another cluster that uses Opteron 2214 quad core CPUs with 1MB cache/core, 8GB of RAM and kernel 2.6.28 (x86_64). On the Intel cluster the code generates barely any system load when I look on top but on the AMD cluster it can generate over 50% of system load. On the intel machines my process can generate a constant load of 3, while the load generated by the process on the AMD machines is about 1.6.
Does anybody know what could cause this? Could it be the version of the kernel or the difference between the CPUs (for example, the much smaller cache of the AMD CPUS)? My software and all its dependencies are the same on both clusters. I am also using the exact same version of GCC to compile everything.
I tried googling around but i cant find anything related to this: everyone seems just interested in random numbers, so when it comes to random letters there is a lack of informations. However, i am trying to figure out a wait to get a random letters string that matches a simple rule: it must be a sequence of consonant+vowel. So for example, these are some 6 letters strings i would like to obtain: wolupa, tafoke, zewevu, cupimo.
View 3 Replies View RelatedI am trying to write a loop to open four main-data-files. At each open of the main-data-file, I want the loop to open another four sub-files and split the data from the mail-data-file according to the creteria and dump into the four files. When the loop goes to the second main-data-file, it shall generate another 4 sub-files with different file name. And the process goes on. That means I will have total of 16 sub files for the four main-data-files. Each four files from the 16 files shall have specific name on it. Based on the code which I given below, I would say when the file at UNIT=100 is opened, 4 new files needed to be opened as well. They are:
maximum_dist_001_064.dat
maximum_dist_065_128.dat
maximum_dist_129_192.dat
maximum_dist_193_256.dat
Is it possible to generate keyboard event "Ctrl+c" from a shell script code.? I have written a shell script to compile my application and copy it to the server home directory, inorder to run my application I need to start the server (by running a shell script). But before that I need to stop the the currently running instance of my server. To do that I have to generate a keyboard event (Ctrl+c which I press it manually). I want to automate the entire process by writing a shell script I am able to run the server just by adding ./run.sh in my shell script. But before that to stop my server can I generate a keyboard by using a shell script event(ctrL+C) to stop server.?

View 3 Replies View RelatedI want to validate a web form using PHP. I spent ages confusing myself with client side scripting and realised until I worked out it is not what I want. My problem is that now I am looking at PHP and everything is mixed up in my brain. I need to point out that PHP is very new to me! This is what I already have:
1 An html page with my form on it.
2 PHP page which emails the contents of the form to me.
The above works well. For the sake of clarity, here are my pages (cut down to the essentials where appropriate): My html form:
first name surname
Email
Home phone
Mobile
Work phone
I have read and understood your terms and conditions. My php script (regform.php)
$receiver = 'me@email'; $subject = 'New registration'; #$message = 'This is a new registration.'; $surname = $_POST['surname']; $firstname = $_POST['firstname']; $address = $_POST['address']; $email = $_POST['email']; $homeph = $_POST['homeph']; $mobileph = $_POST['mobileph']; $workph = $_POST['workph']; $time = $_POST['time']; #from here $oldaddress = $_POST['oldaddress']; $DOB = $_POST['DOB']; $elect = $_POST['elect']; $job = $_POST['job']; $salary = $_POST['salary']; $employer = $_POST['employer']; $benefit = $_POST['benefit']; $smoke = $_POST['smoke']; $claim = $_POST['claim']; $children = $_POST['children']; $children2 = $_POST['children2']; $pets = $_POST['pets']; $pets2 = $_POST['pets2']; $require = $_POST['require']; $terms = $_POST['terms']; $rooms = $_POST['rooms']; $body = "first name:$firstname

" . 'X-Mailer: PHP/' . phpversion(); mail($receiver, $subject, $body, $headers, "From: $firstname $surname

You can see there are many more form fields than I have shown in my example html form above. What I want is that the following fields have to be filled:
1 mobileph
2 email
3 terms (checkbox)
I would like the user to be asked to fill the form in properly if any/all of the 3 fields have not been filled in. I imagine I need some php in the html page and some more in the php page. I am certainly not asking any one to do this for me but I am really confused. I have googled and copied and pasted and edited for 6 hours and I am lost. What I want is a very simple and clear example of the code needed. Sorry if I sound as if I can't search properly on Google: in this case I clearly can't!

I'm new to php and need some pointers to worth while documentation 'cause I'm getting nowhere I want to make a simple html form that allows me to submit a csv file so that I can work on it.The problem seems to be that if the file is not in the root of the (web) application it won't work.The form doesn't seem to send the path with it so I am unable to (1) know where the file is, I just get the name of the file and (2) I couldn't access the file anyway as it's outside of the apache environment.Is there a way to up the file to memory?

I can easily surf along to the URL [URL] and click the submit button which pokes script.php and everyone's happy. Automating this in iMacros or Selenium - no problem.

Browsing some websites I've found a code for online form where a user provides name, number, etc. Everything is created in html/javascript. I'm just wondering whether it's possible to collect this input and present it in a database form so that I'd be able to see who's provided data and all the details they entered.Actually, it doesn't have to be a proper database (it would probably require php/mysql). It could be a weekly/monthly report (a text file) of people who provided details. The website is hosted by a third party company.This is an html bit:
