Quick string question finding if a string contains a character

hello peeps
is there a quick way of checking if a string contains a specific character
e.g.
myString="test:test";
myString.contains(":");
would be true
any ideas on a quick way of doing it

is there a contains() method in 1.4.2? i couldnt see
it in the docsNo there isn't. But the 1.5 has a contains(CharSequence s) method.

Very Quick Newb Question - Converting Float to String

I created a small program that converts currency for the iPhone. Unfortauntely, I cannot get the UILabel to display my float value. Apparently, NS can though. I found a tutorial that told me simply to use this:
[label setFloatValue:currency];
label is the UILabel
currency is the float value
When I do that with the iPhone SDK, I get this error:
warning: 'UILabel' may not respond to '-setFloatValue:'
messages without a matching method signature will be assumed to return 'id' and accept '...' as arguments.
Any quick advice would be appreciated!
Message was edited by: hollafortwodollas

Simple requirements:
label.text = [NSString stringWithFormat:@"%f", floatValue];
More complex example:
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setFormatWidth:2];
[formatter setPaddingCharacter:@"0"];
[formatter setPaddingPosition:NSNumberFormatterPadBeforePrefix];
lable.text = [NSString stringWithFormat:@"%@:%@:%@",
[formatter stringFromNumber:[NSNumber numberWithInt:hours]],
[formatter stringFromNumber:[NSNumber numberWithInt:minutes]],
[formatter stringFromNumber:[NSNumber numberWithInt:seconds]]];

How to use String Function Find() in a String Value Test?

Hi,
i intend to match a substring of the string returned from my UUT when using a String Value Test - VI call.
I write the returned string to a Local Variable type String (Locals.data_read) and in the Limits Tab - under Expected String Value am using Find(Locals.data_read, "Connected"). When i Check the expression for Errors - i get a warning "Expected String, found Number {64-bit Floating Point}. this value will cause a run-time error."
What am i missing?
Thanks
Kech
Solved!
Go to Solution.

The Find function evaluates to a number:
Number Find(String string, String stringToSearchFor, Number indexToSearchFrom = 0, Boolean ignoreCase = False, Boolean searchInReverse = False)
Returns: The zero-based character index, starting at the beginning of the string, of the first character in the substring. The function returns -1 if it does not find the substring.
It looks to me like you need to do a numeric step type. Not a string value test.
Or you can do something like this:
Find(Locals.data_read, "Connected") < 0 ? "Doesn't Matter What Is Here" : Locals.data_read
Hope this helps,

GREP 'find/change' by list script: find a text string containing different para styles

Hi
I'm don't write scripts but do 'enjoy' copying, pasting and changing existing code/txt files.
I have built a GREP find/change .txt that performs a large number of text edits/changes.
But I'm left with an issue where I have paragraphs of text (styled earlier in the .txt file) that I'm unable to identify using GREP the usual way. I need to identify text in a particular paragraph style, followed by text in another paragraph style.
Is it possible with GREP to create a search string to find: text styled with one paragraph style, ending with a paragraph return, and to include in that selection the following paragraph/s styled with another paragraph style?

What do you mean by I would mark "changing" in "copying, pasting and changing"?
Hi Steve,
I mean I can see a way by modifying some existing code with "find...change" job
1. set criteria to findGrep
2. store findGrep() in an array
3. check each found object if next paragraph matches some new criteria
4. run changeGrep() if true

How can I find out the strings that will be presented to the UI

Hi All,
I am working on a Swing based application (Swing based UI)
I am requested to do the following on the bytecode of that application:
I am supposed to find out what strings from within that bytecode will be presented to the UI and what will be used for an internal usage.
i have no way of running the application to verify that, i can only work on the static bytecode files.
hard question ha?
Thanks,
EItan.

You would of course have to run it. Either via a VM or recreating a VM yourself.
As an example of that how would you figure out what string occurs in the following (pseudo) code?
String msg = (cnt > 1) ? ("files=" + cnt) : ("file=" + cnt);
if (cnt > 1) DisplayMessage(msg);

Oracle Spatial function to find nearest line string based on lat/long

Hi,
Here is my scenario. I have a table that contains geometries of type line strings (the roadway network). The line geomteries are of type Ohio state plane south (SRID 41104).
I have a requirement - given a lat/long, find the line string that snaps to that lat/long or the nearest set of line strings within a distance of 0.02 miles.
This is a typical example of trying to identify a crash location on our roadway network. The crashes being reported to us in lat/long thru the GPS system.
How can i acheive this through any spatial functions?
Thanks for the help in advance.
thanx,
L.

Hi L,
That is not the way I would do it. I would convert my road segments to LRS data, then you can do all queries on the same data.
Or, if you do not want to modify your original data, create a copy of your road segments with the same ID's and convert the copy into LRS data. If you keep the ID's identical, you can easily use geometry from one and LRS data from the other - as long as you are sure the ID is the same.
Which will make the workflow a bit easier:
1. Use SDO_NN to get the closest segments
2. Use SDO_LRS.PROJECT_PT to get the projected point
3. Use SDO_LRS.GET_MEASURE to get the measure
And most of these you can incorporate into one single query. Now I am writing this of the top of my head (It's been a while since I played with LRS). so this has not been tested, but something like this should work (but could probably be greatly improved - it's getting late for me :-) ):
SELECT
SDO_LRS.FIND_MEASURE --//find_measure needs an LRS segment and a point
    SELECT            --//here we select the LRS segment
      r.geometry
    FROM
      roadsegments r
    WHERE SDO_NN(r.geometry,    --//based on the given GPS point
                 sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
                 'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE'
SDO_LRS.PROJECT_PT --//We project the point on the LRS segment
      SELECT         --//here we select the LRS segment (again, which could probably be improved!!)
        r.geometry
      FROM
        roadsegments r
      WHERE SDO_NN(r.geometry,
                   sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
                   'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE'
    sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL) --//The GPS point again
AS milemarker from dual;So it is not as complicated as you think, it can easily be done with just one query (SQL can do a lot more than you think ;-) ).
Good luck,

How to find a specific string in Entire database?

Well i know this question is posted numerous times here but i m complete noob understanding the solution given on the net.
Let me introduce the entire scenario .
We have an application, which keeps on sending emails from an X employees account.
We are using Oracle 11g as database .But the problem is we don't know which table to search for the value.
All we have is Database credentials and x employee's name.
Is there any way we can find out which table contains the name so that we can change it accordingly.
I m using plsql developer to connect to the database.
One solution that we got from internet goes as below.

[http://www.club-oracle.com/articles/oracle-find-all-tables-with-column-value-154/ |http://www.club-oracle.com/articles/oracle-find-all-tables-with-column-value-154/ ]
As per the solution i had to create a procedure as below .
create or replace
procedure find_string( p_str in varchar2 )
authid current_user
as
l_query long;
l_case long;
l_runquery boolean;
l_tname varchar2(30);
l_cname varchar2(30);
type rc is ref cursor;
l_cursor rc;
begin
dbms_application_info.set_client_info( '%' || upper(p_str) || '%' );
for x in (select * from user_tables )
loop
l_query := 'select distinct ''' || x.table_name || ''', $$
from ' || x.table_name || '
where ( 1=0 ';
l_runquery := FALSE;
l_case := NULL;
for y in ( select *
from user_tab_columns
where table_name = x.table_name
and data_type in ( 'VARCHAR2', 'CHAR' )
loop
l_runquery := TRUE;
l_query := l_query || ' or upper(' || y.column_name ||
') like userenv(''client_info'') ';
l_case := l_case || '||'' ''|| case when upper(' || y.column_name ||
') like userenv(''client_info'') then ''' ||
y.column_name || ''' else NULL end';
end loop;
if ( l_runquery )
then
l_query := replace( l_query, '$$', substr(l_case,8) ) || ')';
begin
open l_cursor for l_query;
loop
fetch l_cursor into l_tname, l_cname;
exit when l_cursor%notfound;
dbms_output.put_line
( 'Found in ' || l_tname || '.' || l_cname );
end loop;
close l_cursor;
end;
end if;
end loop;
end;
Well i have copied the code to sql window in plsql and executed .But whenever i compile the procedure it says there is an error .
Not sure what kind of error hidden in the procedure.
If any 1 has any better idea please share.

Use REGEXP_INSTR to find a text string with space(s) in it

I am trying to use REGEXP_INSTR to find a text string with space(s) in it.
(This is in a Function.)
Let's say ParmIn_Look_For has a value of 'black dog'. I want to see if
ParmIn_Search_This_String has 'black dog' anywhere in it. But it gives an error
Syntax error on command line.
If ParmIn_Look_For is just 'black' or 'dog' it works fine.
Is there some way to put single quotes/double quotes around ParmIn_Look_For so this will
look for 'black dog' ??
Also: If I want to use the option of ignoring white space, is the last parm
'ix' 'i,x' or what ?
SELECT
REGEXP_INSTR(ParmIn_Search_This_String,
'('||ParmIn_Look_For||')+', 1, 1, 0, 'i')
INTO Position_Found_In_String
FROM DUAL;

Question: Quick Look in Finder; problems with alpha channels

Hi
"Quick look" in Finder is great for quick presentations of a folders selected contents but it only works with images that contains no alpha channels or masks. Is there any way to work around this to display say PhotoShop documents with alpha channels? Or any plug-ins/applications that can help?
thanks.

This has been broken forever in OS X, and I don't know why, because it used to work just fine. I suspect the engineers did something to QuickTime that causes this problem, but it has been borked for so long I don't remember when the ability to correctly display files went wrong. I just remember that once upon a time all sorts of things from Apple worked correctly in displaying such files, but pretty much nothing does now. This includes the Finder, Preview, QuickLook, and various third-party image browsers that use Apple's own system level image handling abilities, such as VitaminSee or CocoaViewX. When I need to actually see what's there, I browse with Adobe's Bridge.

Find and replace string in file

hi,
i need to find and replace text (string) data in about 100+ files, i've decided to write a small java program to do it but i'm stuck on how to replace.
here is what i'm heading towards:
class ReplaceString {
BufferedReader in;
BufferedReader os;
public static void main(String args[]) {
    ReplaceString obj = new ReplaceString();
    obj.replace();
   void replace() {
     try {
       in = new BufferedReader(new FileReader("a.txt");
       os = new BufferdWriter(new FileWriter("a.txt");
       // read until end of file
       String currentLine = new String();
       while((currenLine=is.readLine()) != null) {
         // if matching text then replace????
         if(currentLine.equals("Version 001") {
            // how to now replace the Version 001 with Version 002???
     }catch(IOException e) {
        System.out.println(e);
        in.close();
        os.close();
     in.close();
     os.close();
}the above code i just typed so there might be errors, but looks ok to me, is there any way once i find the string i want to replace, to replace the string with another string. basically i want to replace all occurrences of the text "Version 001" with "Version 002"
Thank you.

Is it always true, as in your example, that the replacement is the same length as the existing string? If so, this one's easy.
Is it also true that you don't need to worry about 16-bit chars? (Again, as in your example.) If you're using just ASCII characters, this gets easier still.
1) Segregate the file I/O from the search/replace process.
2) Main becomes:
readFile();
replace( "this", "that" );
writeFile();Use a byte array buffer, defined in your main class. Fill it via the readFile() code. Use a RandomAccessFile, check its length() to allocate your byte array, then do a single read() to fill the buffer.
A brute force search will certainly work: scan for the first search character, then check the rest for a match, replace if you've got a match and continue scanning. Alternative if your file's aren't too big: create a String from the byte array:
// buffer is a byte array
String s = new String( buffer );And use the String.replaceAll() to do the search/replace. Recover the buffer with:
buffer = string.getBytes();A single write() and close() should handle the remaining work.

C++11 is approximately a superset of C++03. If you write in the common subset, the code will compile in any mode. For example, a basic hello-world program
#include <iostream>
int main() { std::cout << "Hello, world!\n"; }
will compile and run as C++98/03, as C++11, as C++14, and I'm sure will also work with the next standard, planned for 2017.
But if you use syntax or library types and functions that are new in C++11, the code will not compile as C++03.
In my previous post, I might have sounded too negative about compiling C++03 code in C++11 mode. If you have a C++03 program that is intended to be portable, and that works with different compilers on different platforms, chances are good that it will continue to work in C++11. The chances are very good that only minor modifications will be needed.

Flatten to string for sending through TCP/IP contains CRLF characters

Hi,
I'm using a 'flatten to string' function to send some data through TCP/IP.
To minimise delays, I use the CRLF mode so that the receive function returns as soon as it receives a CRLF sequence (termination character).
I noted that every now and then only part of the data is transmitted because the flattened string itself sometimes (albeit rarely) contains CRLF characters.
I was wondering if this is correct behaviour, or if I'm missing something.I expected flatten to string to produce pure ASCII strings without special characters.
Now I first have to scan the string and replace possible CRLF characters by some known series of characters and do the opposite on the receiving side, and hope that this particular sequence never occurs.
Any comment is appreciated,

Hi,
thanks for the feedback. I'll use the way you describe, by first sending the number of characters to expect.

Make sure you are consistent with the format for the number of butes. That is, always use an 8, 16 or 32 bit value. Which one you use is up to you and will depend on the size of your data. A 32 bit value is the most common size to use. Anyway what I am basically saying is that if you are inconsistent with what size number you use for the size you will get inconsistent results when you read the data since you will be interpretting the size incorrectly some of the time.
