  • TCPDF Specific border for different sides

    - by Metropolis
    Hey Everyone, I just started using TCPDF (output with HTML), and I do not understand why I can not have an inline CSS style for border like the following, style="border-right: 1px" After looking at some of the examples, the only place I see borders being used is on a table using the border="1" property. This is very frustrating, and I hope there is a way for me to use all inline CSS instead of old HTML attributes like "border". Thanks for any help, Metropolis

  • Arduino (processing) Library in Netbeans and control

    - by Casper Marcussen
    Hello everyone I am trying to control 4 LEDs and getting analog input from 4 contacts. The program is written in java, so to gain acces to the functions of arduino, such as AnalogRead() and setting an LED to high or low, would importing the processing library let the program use those functions? I was also wondering, if the program, will be transferred to the arduino it self, or the java program will just pull the data from the pins?

    Hello everyone, I am trying to assign a regular expression result to an array inside of a bash script but I am unsure whether that's possible, or if I'm doing it entirely wrong. The below is what I want to happen, however I know my syntax is incorrect: indexes[4]=$(echo b5f1e7bfc2439c621353d1ce0629fb8b | grep -o '[a-f0-9]\{8\}') such that: index[1]=b5f1e7bf index[2]=c2439c62 index[3]=1353d1ce index[4]=0629fb8b Any links, or advice, would be wonderful :)

  • Porting SHA512 Javascript implemention to Actionscript

    - by AAA
    Hello Everyone, I am wondering if anyone can help me in porting a SHA-512 implemention in Javascript to Actionscript. Since both Javascript and Actionscript share the same origin, I think porting it will be easy for people who are used to Actionscript. The code for sha512 in javascript can be found here: http://pajhome.org.uk/crypt/md5/sha512.html Thank you.

  • ideas for a distributed cache proxy server

    - by Neeraj
    Hi everyone! I am implementing, a distributed cache proxy server.I have an idea of the HTTP and related stuff, so i am rather concentrating on the sub part "Distributed data storage". From some search on web i found that this could be done using Distributed Hash Tables(DHT). I was wondering if there exists some kind of library for this preferably in C/C++. Any better suggestions for the same will also be appreciated.

  • Delete Drag and Drop Behavior of IKImageBrowserView

    - by PF1
    Hi Everyone: By default (it seems), IKImageBrowserView enables drag and drop to locations in the Finder. I would like to turn off this behavior but am unsure of how to do so. I was thinking that perhaps implementing the NSDraggingDestination protocol and overriding it could solve this, but so far it hasn't worked for me. Thanks for any help!

  • Does anyone know if WordPress has builtin PHP validation functions?

    - by racl101
    Hi everyone, I am trying to build a form in WordPress and taking advantage of all its built-in functions but I am hard pressed to find any functions that do form validation. I figure those kinds of functions have to exist in WordPress but I couldn't find any because its documentation is sparse and spread out in some respects. Would anyone have any useful links to documentation and tutorials by any chance?

  • Counting Alphabetic Characters That Are Contained in an Array with C

    - by Craig
    Hello everyone, I am having trouble with a homework question that I've been working at for quite some time. I don't know exactly why the question is asking and need some clarification on that and also a push in the right direction. Here is the question: (2) Solve this problem using one single subscripted array of counters. The program uses an array of characters defined using the C initialization feature. The program counts the number of each of the alphabetic characters a to z (only lower case characters are counted) and prints a report (in a neat table) of the number of occurrences of each lower case character found. Only print the counts for the letters that occur at least once. That is do not print a count if it is zero. DO NOT use a switch statement in your solution. NOTE: if x is of type char, x-‘a’ is the difference between the ASCII codes for the character in x and the character ‘a’. For example if x holds the character ‘c’ then x-‘a’ has the value 2, while if x holds the character ‘d’, then x-‘a’ has the value 3. Provide test results using the following string: “This is an example of text for exercise (2).” And here is my source code so far: #include<stdio.h> int main() { char c[] = "This is an example of text for exercise (2)."; char d[26]; int i; int j = 0; int k; j = 0; //char s = 97; for(i = 0; i < sizeof(c); i++) { for(s = 'a'; s < 'z'; s++){ if( c[i] == s){ k++; printf("%c,%d\n", s, k); k = 0; } } } return 0; } As you can see, my current solution is a little anemic. Thanks for the help, and I know everyone on the net doesn't necessarily like helping with other people's homework. ;P
