Hi, now I need to convert the content of a JTextField intto a float point number!
How can I do that ? And to convert the content of a JTextField into a double value?
Thanks!

Urgent pl. I want to extract float from string (%f %s) or (%s %f) separate

I want to extract float from string (%f %s) or (%s %f) separated by tab, whitespace etc., Since I am using jdk1.3.1 I can't use regular expression can anybody suggest a simple (one or two or few line code - compact) to get the float in (sign+/-)#.#### format ignoring other characters ?
I tried:
e.g.,
String d="4.000 [tab]4";
source string resulted from "SUBSTRING query of mySQL" can be of :
" -4.543 XYZ ",
" XYZ -4.546 ",
" xx-yy 6.58 3 ",
"6.0 xxx yyy zzz",
the expected results for float from the string should be:
-4.543
-4.546
6.580
6.000
If String containing data separated by comma:
e.g.,
"4.120     1     ,
AAXXFE     ,4.206     1     ,
     4.000     1,
     4.201     1,
     4.189     1,
     4.204     1,
S     DDERSF-RSA"
The result should be: "4.120,4.206,4.000,4.201,4.189,4.204,0.000"
The string is created by:
ResultSet rs1 = stmt.executeQuery(S1);
while (rs1.next()) {
String d = rs1.getString("SUBSTRING(FIELD1,LOCATE(\""+s2[i]+"\",FIELD1)+"+ k_st + ","+ length+")");
System.out.print(d+",");
May be I don't know how to use the following:
float f1 = Float.parseFloat(d);
===
String pattern = "###.###";
//float value = -2100.578f;
DecimalFormat myFormatter = new DecimalFormat(pattern);
String output = myFormatter.format(d);
System.out.println(d+" " + pattern + " " + output);
===

Hi
You made the best choice. JRegex is closer to java.util.regex.* and fine works with excellent performance in any JVM version so you can use examples/tutorials from both JRegex and Java.Sun.Com to learn more about regular expression.
About the regular expression in my last post, there are two capturing groups: the first for float numbers in IEEE format specification (also see Java Language Specification) and the second for any sequence of chars, groups using with any amount of blank spaces (spaces, tabs, etc :: see regular expression definition) as delimiter. The anchors "^" and "$" are being used to exactly match pattern in target string and you can relax this constraint as needed.
How to use JRegex? no secrets!
import jregex.*;
// a float number and string with any blank delimiter
String patternString ="^([+-]?(?:\\d+(?:\\.\\d*)?|\\.\\d+)(?:[eE][+-]?\\d+)?)\s+(.*)$";
Pattern pattern = new Pattern(patternString); // different from Sun regex package syntax
// below is identical in both packages
Matcher m = pattern.matcher(anyTargetString);
if (m.matches()) {
Double d = Double.parseDouble( m.group(1) );
String scratch = m.group(2);
// your stuff goes here
..Remember to put JRegex jarfile in classpath!
Regards and Success.

Iphone ios5..I upgraded to ios5 on my iphone 4 and in the demo video on the Apple website it shows a cute animation screen with the user dragging what appears to be balloons on a string how do you access this screen?

iphone ios5..I upgraded to ios5 on my iphone 4 and in the demo video on the Apple website it shows a cute animation screen with the user dragging what appears to be balloons on a string how do you access this screen?
Not sure if this is a game or app or not...it shows nothing about it and explains nothing about it...but it is there on the demo video on the apple website for the add to upgrade to ios 5...it shows the user dragging threads and the little icon monster at the bottom of the screen catches them

Yea thats a game called "Cut the Rope" and it can be found in the App Store for $0.99 or you can buy the Lite version for free.

BigString to Big String - how do I detect index of upper case?

bigString to Big String - how do I detect index of upper
case?
Is there a way to detect, insert space and replace the upper
case letters in a string?

Something like this?
<CFOUTPUT>#REReplace("bigString", "[A-Z]"," "&
Mid("bigString", REfind("[A-Z]", "bigString"),
1))#</CFOUTPUT>
This will at least give you a break at the first upper case
letter. You can then replace the first character in the result with
an upper case as well, which I didn't do, since I figured that you
knew how to do that.

So... if there's no floating point math, how do all those calculators work?

I see there's no floating point math support in J2ME.
So how do those calculators work? There's lots of 'em for download.
I have an app that's almost done; all I need to do is finish the calculations, but I need to read Strings from TextArea's and compute values based on them.
What am I missing?

You can use third party libraries
(MathFP http://www.jscience.net)
or
implement them with classical algorithms.

EastWest Symphonic, LA Scoring Strings - How many instances can you run?

Hi - After investing in a new quod core recently and been really depressed by the performance I'm getting I wondered whether users of EW Symphonic Orchestra and/or LA Scoring Strings, Vienna Symphonic etc... could share with me how many instances they can load and run in a mix.

Hi,
i understand your frustration
Below is a list of the things I had do to to make my system usable:
1. Turn Airport & BlueTooth : OFF
2. Apple System Preferences:
Energy Saver: Set Computer and Hard Drive to: Never Sleep,
Software Updates: Check for update: Uncheck
3. Logic Preferences, Audio , Devices:
I/O Buffer Size 512
Software Monitoring: OFF
Process Buffer Range: Large
Audio Units Manager: Uncheck all AU plugins not being used!
4. Logic Preferences, Audio, General:
Track Mute/solo: CPU-saving(Slow Response)
Sample Accurate Automation : OFF
Plug-In Delay Compensation: OFF
5. Assign ALL tracks thru Buss's, See Link below
http://support.apple.com/kb/HT3161
6. Keep a muted audio track in the arrange page and have it selected
LOgic uses additional CPU power if a midi track is selected
7. Keep at least 50gb or more of free space on the hard drive
8. Run the freeware program Mac Janitor
9. Do not run any other programs during the Logic Session. Close all programs not being used.
10. VERY IMPORTANT! Restart computer to flush ram. Do this each and every time you reload your Logic Sequence.

I hope this helps

Float to string

why this doest work?
error: float cannot be dereferenced
System.out.println(Float.parseFloat(3.0).toString())
can any expert tell me?
thx
your
terry

System.out.println(Float.parseFloat(3.0).toString())Not an expert but the parseFloat returns a native which doesn't have a toString method. I would use the other post that creates a new Float() object. Or just take the toString() off and it should work. Natives print just fine. Like in...
int z = 123;
String x = "Hello, my tag is " + z + "#";
// x will print "Hello, my tag is 123#";

Regex backreference combined with string - how to separate

Hi,
I'm doing a replace with a backreference but the backreference is being interpreted as part of the string instead. If I insert a space it is interpreted correctly but I do not want to have a space.
Here's the code:
$regex = '(<add key="Global.LoadBalancer.ServerFarmIPAddresses.CSV"\svalue=")(?:[^"]+)("\s/>)'
$fillerString = '$1127.0.0.1$2'
The expected result should be to change this string:
<add key="Global.LoadBalancer.ServerFarmIPAddresses.CSV" value="10.10.10.10,10.10.10.9,10.128.128.211,10.128.128.111" />
And change it to this one:
<add key="Global.LoadBalancer.ServerFarmIPAddresses.CSV" value="127.0.0.1" />
But instead it changes it to this:
$1127.0.0.1" />
How can I separate the $1 from the Ip address without adding a space?

Put curly braces around the "1" and "2" in the replacement string:
$fillerString = '${1}127.0.0.1${2}'

Loading a binary string How do i do it?

Hi,
I have saved a string as binary data so that there are no spaces between each letter. I am trying to work out how to load it but the book I have is awful. I don't want to restrict the length of the data that can be read in. Is there any way to get the size of the incoming file in bytes and then create a char buffer big enough to then copy the loaded data into?
Any help would be much appreciate but please be really clear and step by step as this area is completely new to me.
Many thanks
Dylan

1. All strings are saved as binary data, so you haven't done anything special.
2. You didn't say what the actual encoding scheme is that you used. But in general, the answer to your question is "no". The reason is that many encodings require a variable length for each character that depends on the actual character encoded.

Float to string conversion

return numOfItems;
When I call the method "getCost()" from a jsp program, I get the error message
Error: java.lang.Float: method parseFloat(Ljava/lang/String;)F not found has been reported.
I think the mistake is in conversion.
Please help me.
My thanks in advance.

Why don't you try the following:
Float tmpFloat=new Float(tmpItem[3]);
totalCost += (Integer.parseInt(tmpItem[4]) * tmpFloat.floatValue();

Float to string conversion (E-\d)

i'am creating a compiler that needs to convert float vaues to string values.
if the float values become very small java produces an output as this: 9.8E-4
is ther a way retrive 0.00098 instead of the computerized scientific notation?

Try java.text.DecimallFormat:

"Midi Events" Environment, floating window. How to repeat in next project?

This is proving a slightly bizarre, lovely but rather annoying issue.
I have searched high and low on the web today for an answer, I cannot find it. allow me to explain, I've just upgraded to Logic Pro 9, and after enjoying the Thievery Corporation demo I set to work on scoring a video doc of mine, as really I'm an ex musician who now works ostensibly in Final Cut, on my Mac Pro.
Anyway my first Logic project is going well, lots of plugin purchased, first 5mins complete, now here's the thing, when I open my first project a floating window also appears with it, and it is listed separately from arrangement on the window tab, in this case arrangement is called "imtro" and the floating window is called "imtro:Tempo". It opens and closes with the project, if I hit the top corner of the floating window to close it goes and closes, and cannot be re opened unless I close the project.
I thougt it was a new feature in Logic 9, as it operates as a lovely appregiator inside of Logic. It had 4 boxes (orange) Midi Effects (On/Off), Arp Starts (immediately/on first 1/1, 1/2, 1/4 etc) then a 1/16 appregiator, and 1/8 appregiator button, both with all the varaitions you could imagine, and finally a Delay button. And put simply when I select any track in the arrange window, and swith to Midi Effects to On, it plays wonderfully appreg..., in record it creates all the notes in the piano scroll and event list as I'm playing.
Trouble, once dismissed, I cannot recall it without closing the project, reopening the project.
Worse yet on starting new project for the next piece of music in video doc' I've discovered, it's not a feature I can find anywhere, what's going on?
Back in the original project if I pull the window by the right corner there's a whole bunch of boxes, and it turns out this is an Environment. The trouble is in any other project I open the Environment window from the window tab, and Midi Effects environment is nowhere to found. So I learnt how to import environments from my first project into this project, but cannot seem to get the environment to float over the project where clicking on track in the Arrange window allows the Midi Event float to effect the track I'm playing, yes you can reassign the header of the track to it but it doesn't work as well.
Now have I just stumbled on a new feature, I heartily recommend for Logic 10, or am I missing something? Or is this some kind of glitch or corruption, which just appears to be a good one? I certainly can't read about anywhere, and I can't repeat it by just calling it up in the project? What am I missing? I wonder if Tempo being in it's name is significant, as a floating window, when imorted in Midi effects it appears as the "project name:Enviroment: rather than "project name:Tempo".
Anyone?

The layers in the env. are accessed by the drop down menu at the upper left of the env. window. It has a text field and a downward facing triangle. You may need to go into the view menu, and enable the inspector - it's at the top of that. You can also just hit "I" (as in the letter 'eye').
When you are importing, you should select the 'total replace' option. There are connections that are not made if you just import that layer.
Edit: I should add that 'total' replace will get rid of any instruments you already have, so use it with caution. If you have a bunch of work done, investigate merging.

Given a string, how do you find the numeric value in sparse ring?

Situation: I receive the string value of the sparse ring, and a control reference to the same type of control, but not the control that sourced the string. How can I convert the string, into the actual numeric value of the ring? For example:
Using the "VISA Select Event Type" ring (Functions -> Instrument I/O -> VISA -> Advanced -> Event -> Select Event Type.ctl), lets say I get the string "ServiceRequest" how do I convert that into 1073684491, the actual value of the ring?
This is a rework of an existing function that worked fine with "normal" rings.
Thanks.

Unfortunately this method will not work, its a generic routine that must be able to take any ring, so I can't hardwire the cases to known outputs. And, of course, searching the array of Strings[] will just find me a useless index.
My interm solution is this:
1) pick a small, but likely range of possible values for the ring
2) iterate through these values, assigning each one in turn to ring
3) read the RingText property to see if it matches the passed string
4) if it does, then exit. If it doesn't keep looping.
5) if no value produces a matching string, declare defeat (raise an error or produce other output that indicates a match could not be found).
The routine only runs in the UI so I am not too concerned about the time delay this method will i
mpose, but I would greatly appreciate a smoother solution.
Thanks for your suggestions.
