Help me again pls !
Hello ppl! I have a another assignment that I need some help with. I'm supposed to write some program that calculates a sequence of numbers using the fibonacci (I'm not joking this is what my tutor said it was called) sequence where the 0th and 1st numbers are 1 and print the first 5 numbers that are greater than 100 to the console. He said I should do it in 'recursion' (like, whatever! It's hard enough without doing it in french or something). Can someone help me pls because it has to be finished today.
Thanx!

At the very least, I recommend you restart your router, (your internet box).
More detail on your problem is needed - are you in a submarine? On the moon? On a tropical island?
You can help yourself by providing as much info as you can about your present situation - what kind of router do you have? Have you moved it? DId you update it? Did you do anything to change your setup, and if you did, what? -
This happens not infrequently. When it does I routinely apply Dr.Smoke's remedy of trashing 3 library files and rebooting and Mac Help works again.
However this time it displayed the alpha index but declined to open the page corresponding to the letter I chose.
I wonder if there is a further treatment that could wake up this help file, or a test to pinpoint the cause of the dysfunction?1. You wrote: "tep 3 of Solution 3 of "Help Viewer links do not work" refers to Incompatible Startup or Login Items, for which the recommanded solution is to update to Mac OS X 10.4.6 or later and then reset Help Viewer"No: that's incorrect. Step 2 refers to the update. Step 3 refers to "Rule out incompatible Startup or Login Items" and refers you to my "Troubleshooting Startup and Login Items" FAQ.
Seems you've not performed Step 2, either, which will probably solve the problem permanently.
2. You wrote: "Quote:To display the toolbar for Help Viewer, click the elliptical button at the far right in the title bar of the Help Viewer window.Unquote
There is no elliptical button at the far right of the title bar. only the Ask a Question field (typing a word in it sets the spinning wheel turning endlessly)
I cannot control click the HelpViewer toolbar to customize it."Once again, you are misreading the FAQ. The item you quote from above is from the section entitled "Help Viewer does not display a search field under Mac OS X 10.3 or earlier" in the FAQ. That's a new section and follows the section on "Help Viewer links do not work". You should be able to tell it's a new section as the title is larger, i.e. its a new heading. There are links to the individual sections at the start of the FAQ, but the sections run linearly throughout the FAQ.
That new section obviously does not apply to Tiger (Mac OS X 10.4) since it states "Mac OS X 10.3 and Earlier." Under Tiger, Help Viewer's toolbar cannot be customized. That feature was only available in Panther (10.3) and earlier. Likewise, it does not apply to your current problem, but a different problem.
My FAQ covers Help Viewer for Mac OS X 10.2 (Jaguar), Mac OS X 10.3 (Panther), and Mac OS X 10.4 (Tiger). The titles of sections or the details within a section can be version-specific and are noted accordingly.
3. You wrote: "Should I rebuild the OSX desktop? (I have a utility by that name). or go ahead an update to OS 10.4.7?
http://www.apple.com/support/downloads/macosxupdate1047comboppc.html says it is 145Mb!!! "Neither.
You should update to Mac OS X 10.7 using Software Update, which will download just the changes you need for the update. You do not need to download the Combo Update to perform an update.
Some people recommend always downloading and installing the Combo Update. I do not: I think that approach is a waste of time.
4. You wrote: "I am a little reluctant to update because it often creates more problems than it cures."That has not been my experience. While there are often many posts here on the Discussions about "problems caused by an update" they are usually the result of self-inflicted wounds:
• People install updates on already-corrupted systems, making a bad problem worse.
• They are running third-party software, often hacks and interface modifications relying on undocumented features of the OS, that are rendered incompatible with the update.
Granted, some updates have had bugs, but I've personally found that most post-update problems are the the result of user errors or a lack of maintenance, rather than problems with the update.
If your system is properly maintained and not "hacked-up" then you should not have any problems with Software Updates.
Before installing software updates, you may wish to consider the advice in my "Installing Software Updates" FAQ. Taking the steps therein before installing an update often helps avert problems and gives you a fallback position in case trouble arises.
Good luck!

You declare static variables:
Button b2, b3;
but then in your init() method, you delare new local variables when you specify:
Button b2 = new Button(...);
Button b3 = new Button(...);
Since you're declaring and initializing the new local variables, you have never set the static variables to any values. Try removing the type declaration for b2 and b3 in your init() method as follows:
b2 = new Button(...)
b3 = new Button(...)

Need some help with POI pls...
Hi,
I'm currently using POI to generate MS Excel documents from
CF.
I believe it's a great tool because it gave me the
possibility to export the data on different worksheets, etc.
Before using POI, I was just using only CF (see PART 1 in
attached code).
The advantage was that I could display all 3 tables in 1 page
and control their display using plain html.
The disadvantage was that, when the request was to display
each product details on 1 separate worksheet, I was stuck!
And this is where using POI becomes interesting!
However, I've noticed that you can only export 1 query to the
POI, and my question is:
Is there a way to pass more than 1 query to the POI, so that
it displays in the same way as it would using CF (3 different
blocks or tables)?
This is because, even though I have to separate each product
on a separate worksheet, I still need to have the same display i.e.
1 table for the Overall, then a blank column (separator), 1 table
for the "Entries", then a blank column as separator again, and then
1 table for the "Exits". (Forget about the names Overall, Entries
and Exits, this is just an example. I only need to display 3
sections of data on the same sheet).
Now, since I don't know if this is possible or not, I have
tried to work around the problem differently.
What I've done is to create 1 query (see PART 2 in attached
code).
Now, here I've got a big problem, especially if I'm querying
data since inception.
I'm using a MySQL 5.1 database properly partitioned on dates
(yearly) and then properly indexed.
I'm currently using SQLYog Enterprise v5.21 as GUI tool for
my database.
Here are my observations:
1. Querying the data in SQLYog itself takes miliseconds
(around 47ms).
2. Querying the data via a cfquery takes seconds (around 6-7
seconds).
3. Looping through more than 50,000 records to create the
myQry takes around 4-5 mins. If I test it on my PC, I even have to
restart jrun!
Is there any better way to do the following?
1. Populate the myQry.
2. Display the data in 3 "blocks" on each sheet using POI.
Your help will be greatly appreciated :-)
Thanks and regards,
Yogesh MahadnacHi -==cfSearching==-
Many thanks for your reply.
At least I've got one now!
Indeed, I would be very much grateful if you could please
provide me with an example, if possible, via email to

Hello
For some reason, i am using a variable in place of a FIELD, while doing of referring a text field expression syntax, working fine, the syntax is as below shown in (1)*
var myVariable
myVariable = myTextField
(1)* xfa.resolveNode("VISITOR.Page3.SubFrom1." + myVariable + "").access = "readOnly";
Now,
I want to use a vatriable in place(in stead) of COMPLETE text field expression syntax , pls. let me know its syntax(i tries with the below syntax, its not working), as shown in (1)* the above syntax
xfa.resolveNode(myVariable).access = "readOnly";
Thank youHi,
Your syntax is correct the problem is that It doesn't look like you have change the variable to be the entire path, so for the code
xfa.resolveNode(myVariable).access = "readOnly";
the myVariable would have to be set to be
myVariable = "VISITOR.Page3.SubFrom1.myTextField";
Hope this helps
Malcolm
