Programming :: Insert Elements Into A Combobox From A Database Using NETBEANS?
Apr 13, 2010
I'm trying to make a combo box which should have elements dynamically taken from a database. I've an Exam Table,and it has columns Sno,Ename,Month,year. i need the combobox to list to the elements that are present in Ename.
i read some things in the web and tried that out in the netbeans. it said to rightclick the combobox and set bind ->elements and bind->selecteditem. But i'm not sure how to set the binding expressions inorder to get the required list in the combobox.

For Perl I need to understand a few things. It's unlikely that anyone will be able to give me direct answers but if they could point outI'm trying to hack down an existing script http://eoylpac.org/source/eoy.pl. What I need to be able to do (in a nut shell):1. Open a database2. Read the values for each uniq id and execute a subroutine for each of those values. (The subroutine already exists in the above file 'do_pdf').

I have a LAMP server. I know sql but I'm currently learning PHP.
Correct me if I'm wrong, but you're supposed to use PHP to insert/select data from the database, right? If so, SQL shouldn't need a port at all.
Apache uses port 80, but it's listening for connections. MySQL uses port 3306, but I've never logged into it from anywhere besides 127.0.0.1/localhost. I have mysqladmin installed and it demands that I give it an IP so I used localhost.
I'm not interested in doing anything remote, so can I block this port? When I say "block" I mean on the router, not locally through iptables. Obviously I have to foward port 80 because that's how people would connect to my server. But once they connect and send something, my server would interpret the data locally and send it back on port 80.

i've got certain functions now declared as static and their being used as pointers. So, moving on I then added a variable which so happened to be used in both static and non static functions. Here's some testbed code, the variable in question is 'window':
Code:
//g++ -Wall -I/usr/include/ -L/usr/X11R6/lib -lX11 -lXi -lXmu -lglut -lGL -lGLU -lm main.cpp -o run
#include <GL/glut.h>
#include <stdlib.h>
[Code]....
In short, I can't see the point of using a class to wrap all of this. Never having been taught programming i'm unsure as to the best method for structuring an application like this. Should (would you design) this initial section be a class?

I have a char*[] array:
Code:
char* myarray[] = {"Hello", "there!", "LQ"};
and I wish to use/ write a function to find the number of elements in myarray (in this case, its 3).
*equivalent of .NET's array.size() that returns number of elements in array
How do I achieve it?

im trying to receive a string from user, then divide it into groups of strings with 3 elements only. meaning if input is:
12345 it should give 123 and 45
123456 it should give 123 and 456
1234567 it should give 123 and 456 and 7
anyway what happens based on my code is that it works fine with first two (when it has groups of 3 elements and 2 element, and also when it has groups of all 3 elements) but for the last case (when makes groups of 3 elements and 1 group of 1 element) it shouws as "123 456 7 D"!! meaning it adds one extra character to the last element out of no where!
here is my code:
Code:
#include <iostream>
#include <conio>
struct array
{

I am trying to learn how to include common elements on every page. At first I made the mistake of calling it ssi but I do not think that is correct in php5. I downloaded phpb3 to look at and they are not doing it that way. they do it like this.
Code...
Problem is I can not find any articles that explain it. I even looked at the php manual and did not find it. Could someone explain this or point me in the right direction.

For a search box on my site, I want a textbox, which will let the user input the term to be searched for, and next to it I want a drop down list that'll have, for example, "Fruit" and "Vegetables" as categories to be searched within. How do I do the HTML for this? (so that the arguments to my search.php script will be eg. "search.php?text=apples&type=fruit" ? )

Is there some way to access HTML elements via javascript through some internal ID?
For instance, given a form like:

I think I've seen some way to do this before but I'm not certain

...and returning the index of the found element in its array.
I have:
for ((i=0; i < ${#array1[@]}; i++)); do
# Read each line of the file test
if [[ $(eval "sed -n '$(($i+1))'p test") == *${array2[0]}* ]]
stuff
I want to find the index of the found substring in array2 and only if it isn't found, move on to the next element of array2. I don't know the size of array2 so that [0] has just got to go.

When I parse a XML file, should I rely on the order of elements?
For example say we have:
Should I rely on the above order?
Would the following still be valid:
I'm trying to find out if a well formed XML document should have an ordered structure, or if it's still valid XML if it has no order.

I recently upgraded from Ubuntu 10.04 to 10.10. All was going well until netbeans started throwing up errors about not being able to find the "stddef.h" header being called from the stdio and stdlib headers. Now I am unable to even initialize variables without failing.
I was using 6.9.1 from the netbeans website, but then I installed 6.9 from the repos alongside, and I still get the same error. Do I need to remove 6.9.1 ( I would rather remove it and keep the repo version), and if so, how do I do it?
where the stddef.h file is located so that I can replace it, or know of any work around?

I've installed krdc in Debian 7 amd64 desktop (with KDE), but I cannot connect to anything with it:
"Connect to" combobox is empty. Entering "rdp://Username@192.168.1.2" shows messagebox "The entered address cannot be handled". "Plugins" list is empty. "apt-cache search krdc" does not suggest any kind of "-plugn"'s that I could install. Deleting "~/.kde/share/config/krdcrc" does not work.
If launched inside terminal, it outputs this:
Code: Select allkrdc(30434)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "KRDC/Plugin" not found
krdc(30434)/kdeui (kdelibs): Attempt to use QAction "remote_desktop_dockwidget" with KXMLGUIFactory!
What's that "KRDC/Plugin" and how to fix it.
Installed packaged:
Code: Select allapt-cache policy krdc
krdc:
Installed: 4:4.8.4-1+b1
Candidate: 4:4.8.4-1+b1
Version table:
*** 4:4.8.4-1+b1 0
500 http://ftp.litnet.lt/debian/ wheezy/main amd64 Packages
100 /var/lib/dpkg/status
While rdesktop is installed and works OK, krdc looks like is dead-unsusable. Or at least it's usibility is hidden somewhere.
How do I make it work? Or should I report a bug?
