Hi
I'm trying out a simple threading application, wherein, I try to detect a list of Bluetooth users in the vicinity.
In its implementation, I've got a Swings form, which contains a 'Start' button and a TextArea.
On clicking 'Start', I look for the devices by calling a method detectData, which has an implementation of its own. When this happens, I ought to have a "Searching for devices..." message...

Drupal or not
I'm trying to develop a website for a bus transportation system which should basically have the following functionality:
1. Classify the users into two - Admins and well, Users.
2.A. When a User logs in, he has the options to fill in his preferences of travel and probably make a payment online.
2.B. When an Admin. logs in, he gets to do the some typical Admin. functionality like scan/screen Users, Buses, edit the map... -
Yes, this ought to work.
But, as explained in my post above, I'm not in a position to sort keys. The libraries I use sort the values directly. Let's assume this constraint to be some specific design issue of mine.
Anyway. Thanks for your time on this. Using binary search and some calculations, I have a O(n.lg(n)) approach to get past this. For now, it should suffice.... -
Umm..That's kinda obvious.
But it doesn't solve my problem.
I was looking for a solution through STL explicitly. How do I do the same when I use stl::sort( ) on a vector<string>?
I can again do it the hard way of comparing the original vector with the sorted vector and do a binary search to get the index of the now-sorted string.
Is there a compact work-around, is what I ask....Leave a comment:

That, I guess, is the hard way of doing it..
Just when I want STL to work its magic, it fails :(
And about a 2-D array, I don't know.. I'm kinda compelled to use vector<string> due to the nature of my application. And the data-set I'm working on is huge. I've managed to sort it quickly through some nice libraries. But then, I now need to get back to their original values and do some comparison/calculation...Leave a comment:

And the bucket way of storing it.. Is it the best idea?
I mean, the domain I work on is quite big, I must say.
And to make matters worse, let's say I'm considering a vector of strings and not a vector of integers :|Leave a comment:

Precisely. I put that with an intent.
I'm considering a stable sort....Leave a comment:

To get back original indices of a vector after sorting it
Hi.
I wanted to know if there's a neat way of getting back the original indices of the elements in a vector after they've been sorted.
For eg:
Before sort :
v = 5 3 3 2 4
After sort:
v = 2 3 3 4 5
I want to now know whether I can obtain the index of v[0](say) as located in the vector 'v' before sorting.
In this case, I should get 3 as... -
Automate building multiple time in Visual Studio 2005
Hi.
I've developed an application on Visual Studio 2005.
The application takes a command line value and performs certain calculations.
Is there a way to automate building my application multiple times so that with each build, I may increment the value of the command line input?
I was wondering if a batch file with nifty commands could do the trick?
Suggestions?
PS:
In the... -
Well, to be honest, it was quite stupid of me to suggest anything of the sort that I did!
I guess it was just the frustration over unsuccessful debugging which resulted in the "hypothesis " of my theory!
A few of hours of good sleep and I find out the little bug and squish it out..
It so happened that I hadn't closed the FILE pointers file3 and file4 before I exited the routine processFiles()....Leave a comment:

Reading from a file
Hi.
I'm developing a program on pattern recognition.
In it, I accept two input files (containing strings) from the user through the command line.
The input files, say input1.txt and input2.txt, are passed to a function processFiles(), which generates permutations of these strings and stores the resultant permutations in two new, generated files, say gen_file1 and gen_file2.
Immediately after the... -
Response.sendRedirect not redirecting
I face a very queer problem. I have written a simple servlet to gather information from a static HTML form and I wish to write to a Database (DB) if the record doesn't exist already.
In order to do so, I have the following snippet from my servlet, DataEntry.java
...Code:protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { -
STL's key_comp()
I was going through the stl::key_comp() function and found it's implementation to be pretty straight forward when it came implementation on integers.
For eg:
...Code:#include <iostream> #include <set> using namespace std; int main () { set<int> myset; set<int>::key_compare mycomp; set<int>::iterator it; int i,highest; -
Mea Culpa.
I had something else in mind, which seems to have sorted itself out.
Thank you.Leave a comment:

Accessing a file through its path
Hi.
Quick thought.
Is one able to access a file purely through its path, when using Java SE 6??
This feature seems to be available in the Java 7 preview JDK in the package nio.file. But what about SE 6? -
Silly me.
I had not made cards , the variable in class CardLayoutSelf static.
Thanks for the help :)Leave a comment:

Yes.
I do realise the significance of the line number, and in my code, it corresponds to the statement:
in the actionPerformed () method.Code:CardLayout cl = (CardLayout)(c.cards.getLayout());
But I simply do not get as to why/how cl could be receiving a NULL value!?Leave a comment:

CardLayout Manager is giving some trouble
Hi.
I have been trying to fiddle around with some layout managers, the CardLayout in particular. The idea I had was : I must be able to accept multiple panels on one frame, i.e, i must have the first panel with a navigation button labeled "Next", and on clicking it, i am expected to see another panel on the frame.
In my sample code, i have three classes: CardLayoutSelf, Page0, Page1.
The design is... -
Could you please point at the code which needs to be modified, with some more details provided.
I am not very comfortable with the terminology and methods as this is the first time i am trying my hand at socket programming.Leave a comment:

This part is solved i guess.
There was a problem with the masking of the IPv6 addresses.
The next problem i have encountered happens to be of a queer nature.
I developed applets for the above code.
