Typecasting string to integer. need help

Hi,
I have the following statement which returns a String but i need to convert to an integer .
properties.getProperty("MAXWIDTH");
Can i do it this way,
int width = (Integer) properties.getProperty("MAXWIDTH");
But it gives me error stating that it cannot convert string to integer.
Please help
Purnima

That's because the value returned from the
getProperty() method is a String. You can convert it
to an int, like this:int width =
Integer.parseInt(properties.getProperty("MAXWIDTH"));[
/code]oh so simple thanks

JDBC:KPRB string size limits-NEED HELP!

Hello All.
Please, I need your help.
I have the problems in Oracle 9.2.0.6 with stored java and jdbc:kprb internal driver.
I try to put string(more than 32K) into LONG-type field using following java class:
import oracle.sql.CLOB;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.io.Reader;
import java.io.CharArrayReader;
public class LongTest {
public static void insertLong()
throws Exception {
Connection con = DriverManager.getConnection("jdbc:default:connection:");
//generate large string
StringBuffer stringBuffer = new StringBuffer();
for (int i = 0; i < 100000; i++) {
stringBuffer.append("qwerty");
String st = stringBuffer.toString();
//put large string to long-type field
PreparedStatement pst = null;
try {
pst = con.prepareStatement("insert into TEST_LONG (ldata) values (?)");
pst.setString(1, st);
pst.execute();
} finally {
if (pst != null) {pst.close();}
But I get error from jdbc:kprb about limitation of data size for this type(LONG).
But it works well in oracle 10.2.0.1...
Has anybody a solution of how to do this in oracle 9.2.0.6???
thanx!

Bit char string...need help

Hi I am trying to convert a bit char string to something useful. Basically I have an activex tool that allows me acess to a serial port based scale.
I send a weight request command and it sends me this gibberish:
°®°° ìb ÇR
Thank I try to do a tostring() and get this:
\u00b0\u00ae\u00b0\u00b0, on line 1, column 21, is not a valid identifer name.
Hmm.. anyone have to deal with bitchar strings coming from serioal ports or know what i am dealing with here?
Thanks
Frank

Basically you need to access the string as a byte array - I think
there's a method getBytes() that you can apply to a string.

Need help in the String Format method

really need help in string.Format method. I would like to show the s in two digit numbers.
for example:
if s is below 10 then display *0s*
the expecting result is 01,02,03.. 09,10,11....
I tried this method, somehow i got the errors msg. pls advise. thx.
public void setDisplay(String s) {
String tmpSS=String.format("%02d",s);
this.ss.setText(tmpSS);
Edited by: bluesailormoon on May 19, 2008 10:30 AM

Apparently, you expect the string to consist of one or two digits. If that's true, you could do this:String tmpSS = (s.length() == 1) ? ("0" + s) : s; or this: String tmpSS = String.format("%02d", Integer.parseInt(s));

Need help for string tokenizer!

I need help in writing out the string tokenizer.. i've got all of the functions written except for the nexttokken function which i am stuck in. Can anyone help me out in writing the function?

An example of splitting string by comma

while (st.hasMoreTokens()) {
System.out.println(st.nextToken());
This is just an example of usage; i would prefer to use split() function instead

Hello,
The best way is to use the HEX to decimal coversion VI in the string pallette. Then, write this decimal directly to your chart. If you are doing it a point at a time put it into a while loop.

Need help in laoding flat file data, which has \r at the end of a string

Hi There,
Need help in loading flat file data, which has \r at the end of a string.

Can someone pls help me to remove escape character \r from the data?
thanks,

Have you looked into the sed linux command? here are some details:
When working with txt files or with the shell in general it is sometimes necessary to replace certain chars in existing files. In that cases sed can come in handy:
1 sed -i 's/foo/bar/g' FILENAME
The -i option makes sure that the changes are saved in the new file – in case you are not sure that sed will work as you expect it you should use it without the option but provide an output filename. The s is for search, the foo is the pattern you are searching the file for, bar is the replacement string and the g flag makes sure that all hits on each line are replaced, not just the first one.
If you have to replace special characters like a dot or a comma, they have to be entered with a backslash to make clear that you mean the chars, not some control command:
1 sed -i 's/./,/g' *txt
Sed should be available on every standard installation of any distribution. At lesat on Fedora it is even required by core system parts like udev.
If this helps, mark as correct or helpful.

Still need help with case sensitive strings

Hello guy! Sorry to trouble you with the same problem again,
but i still need help!
"I am trying to create a scrypt that will compare a String
with an editable text that the user should type to match that
String. I was able to do that, but the problem is that is not case
sensitive, even with the adobe help telling me that strings are
case sensitive. Do you guys know how to make that comparison match
only if all the field has the right upper and lower case letters?
on exitframe
if field "t:texto1" = "Residencial Serra Verde"then
go to next
end if
end
|----> thats the one Im using!"
There were 2 replys but both of them didnt work, and the
second one even made the director crash, corrupting even previously
files that had nothing to do with the initial problem..
first solution given --
If you put each item that you are comparing into a list, it
magically
makes it case sensitive. Just put list brackets around each
item.
on exitframe
if [field "t:texto1"] = ["Residencial Serra Verde"] then
go to next
end if
end
Second solution given--
The = operator is not case-sensitive when used on strings,
but the < and > operators are case-sensitive.
So another way to do this is to check if the string is
neither greater than nor less than the target string:
vExpected = "Residencial Serra Verde"
vInput = field "t:texto 1"
if vExpected < vInput then
-- ignore
else if vExpected > vInput then
-- ignore
else
-- vExpected is a case-sensitive match for vInput
go next
end if
So any new solutions??
Thanks in advance!!
joao rsm

The first solution does in fact work and is probably the most
efficient way
of doing it. You can verify that it works by starting with a
new director
movie and adding a field named "t:texto1" into the cast with
the text
"Residencial Serra Verde" in the field. Next type the
following command in
the message window and press Enter
put [field "t:texto1"] = ["Residencial Serra Verde"]
You will see it return 1 which means True. Next, make the R
in the field
lower case and execute the command in the message window, it
will return 0
(true).
Now that you know this works, you need to dig deeper in your
code to find
what the problem is. Any more info you can supply?

(String)myObject vs myObject.toString() -- Needed Help

Ihave Some thing like
   String myString = Integer.parseInt((String)pageContext.getAttribute("myKey"));In page context I'm storing a reference to my class , but tis line gives me an error. ( Class Cast Exception)
But,
   String myString = Integer.parseInt(pageContext.getAttribute("myKey").toString()); OR
   String myString = Integer.parseInt(" "+pageContext.getAttribute("myKey")); Will solve the problem, please tell me why ?
Thanks in adavnce.

You should try to use the simplest example code you can. Firstly, this
has nothing to do with Integer.parseInt, which return an int not a String
anyway, and pageContext isn't important in this example either. It boils down to:
Object myObject = a reference to my class, whatever that is...
String string1 = (String) myObject;
//versus:
String string2 = myObject.toString();
//or
String string3 = "" + myObject;Is it clearer now?

1) Have you looked up the symbian error -36 on new-lc?
2) Have you tried the example in the response on forum nokia?
3) Is the address "121.97.220.162:8084" accessible from the internet, on the device, on the specified port?
