How to get specific character from a string

I have a value such as: 0-5 or 123-30. This is a combination
from 2 different IDs.
All I need is to get the number on the right (5 from 0-5 OR
30 from 123), any number on the right of the "-" character not
including
the "-"
I'm not sure what ColdFusion function can I use safely.
I said safely since all I can find is either Left or Right
functions. With these 2 functions, I need to specify the number of
character to extract while in my case the application is growing so
the ID may currently be only 1 digit each (0-5) but later it may
grow longer (123-5677).
If anyone know the function, please help me. Thank you!

Something like this?
Mid(string, Find("-",string)+1 ,
Len(string)-Find("-",string))
Since
Mid(string, start, count)
and
Len(string or binary object)
and
Find(substring, string [, start ])
Or perhaps ....
ListLast(string, "-")
since
ListLast(list [, delimiters ])

How to get each character in a string

as in 'C' we use arrays to get each character of a string stored in array.how can we get each character of a string stored in a variable.

Hi,
For that you need to do offset.
for example one variable called VAR contains string 'HUMERAH'.
if you want each character of that string then you need to decalre as many variable as the number of string.
like
data : var1(1),
var2(1),
var(3),
var(4).
var1 = var+(1).
var2 = var+1(1).
var3 = var+2(1).
var4 = var+3(1).
now var1,var2,var3,var4. contains the single characters.

How to extract specific line from a string

Hi guys.
I?m starting to work with java...
i have the following data inside a string variable:
0 rows inserted.
0 rows updated.
0 rows ignored.
98 rows marked as deleted.
0 rows have no country.
3345 rows have no geo.
0 rows are invalid.
what i want to do i to extract the number of rows marked as delete.
I think that i figured out how to extract the number from this line :"98 rows marked as deleted."
but how do i get to that line?
I hope you can Help me. Thanks.

the string is the result from a Function... this function gets the info from a store procedure...
               rta = "Results for " + dh.getSource() + " source:\n" +
dh.getInsertedCount() + " rows inserted.\n" +
dh.getUpdatedCount() + " rows updated.\n" +
dh.getIgnoredCount() + " rows ignored.\n" +
               dh.getDeletedCount() + " rows marked as deleted.\n" +
               dh.getNoCtryCnt() + " rows have no country.\n" +
               dh.getNoGeoCnt() + " rows have no geo.\n" +
               dh.getInvalidCnt() + " rows are invalid.\n";
i can?t change this function...
so i need to work with the returned value...
i what thinking to use the following method to extract te number...
private int GetNumericValue(string sVal)
int iFirst, iCharVal, iEnd;
int iMult = 1, iRet = 0;
char[] aNumbers = "1234567890".ToCharArray();
iFirst = sVal.IndexOfAny(aNumbers);
iEnd = sVal.LastIndexOfAny(aNumbers);
if (iEnd < 0)
return 0;
string subStr = sVal.Substring(iFirst, iEnd - iFirst + 1);
iEnd = subStr.Length - 1;
while (subStr.Length > 0)
iCharVal = int.Parse(subStr[subStr.Length-1].ToString());
iRet += iMult * iCharVal;
iMult *= 10;
if (iEnd <= 0)
break;
subStr = subStr.Substring(0, subStr.Length - 1);
iEnd = subStr.LastIndexOfAny(aNumbers);
subStr = sVal.Substring(iFirst, iEnd + 1);
return iRet;
but i still need the 4rd line to extract the number

How to get specific rows from the vo or Iterator in the backing bean?

Hi,
I have to get the specific number of rows from iterator in the backing bean. means i want to get the records from the VO or Iterator only from 5 th record to 10th record its like rownum in SQL.
We can use rownum in VO sql query. but there would be a performance issue with that ...
SO i am trying to get the rows from ADF Iterator once we fetch from DB.
Is it possible to do that ?
Do we have any way to set the pointer to the VO/Iterator like setFirst() and after that setMaxResult to retrun the rows between first and maxresult..
Thanks

If this is for pagination, then af:table offers pagination by design when you set accessmode=RangePaging or RangePagingIncremental in VO. Paginated queries are fired when scroll down in the table. Explore this option before you try out any custom solution
To answer the question,
Note: same logic i have implpemented ADF with EJB ..In EJB Query class we have setFirst(int) and setMaxResult(int) methods...simply i did setFirst(30) and setMaxResult(10)..It worked fine...Theoretically speaking the same can be achieved by setting setRangeStart() on the viewobject(which in turn sets to the default rowset) and by setting max fetch size on VO + accessmode=RangePaging. However when you use table with ADF binding, these will be overridden by the binding layer. If you are not using ADF binding, then the above is same as what you did for JPA entity. Other option is, you build expert mode VO with rownum for this special case, which will work if you dont need to set accessmode=RangePaging for VO.

How to get numeric data from a string using t-sql

How can I read a specific character from a text file?

Hi All!
I would like to read a specific character from a text file, e.g. the 2012th character in a text file with 7034 characters.
How can I do this?
Thanks
Johannes

just use the skip(long) method of the input stream that reads the text file and skip over the desired number of bytes

How to get a formula from the user from a text box in a webpage

Hi. I would like to know how to get the formula from the user who enters in a textbox. This formula can have any number of variables starting with a and goes on.
The complexity of the formula can go upto sin, cos, ln, exp. Also user enters the minimum and maximum values of these variables. Based on a specific algorithm (which I use) I would calculate a *set of values, say 10, for each of these variables, substitute in the formula and based on the result of this formula, I select ONE suitable value for each of the variables.
I don't know how to get this formula (which most likely to be different each time) and substitute the values *which I found earlier.
Kindly help me out in this issue.
Thanks

The textbox is the easy part. It's no different than getting a String parameter out of an HTTP request.
The hard part is parsing the String into a "formula" for evaluation. You'll have to write a parser or find one.
Google for "Java math expression parser" and see what you get.
Or write your own with JavaCC.

How to get specific cell or whatever is in your datatable?

All there is in my datatable is one value loaded. Here's my code, but how do i convert that datatable to a string?
var fileName = string.Format("{0}\\file.xlsx", Directory.GetCurrentDirectory());
var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.12.0; data source={0}; Extended Properties=Excel 12.0;", fileName);
OleDbConnection connExcel = new OleDbConnection(connectionString);
connExcel.Open();
DataTable xlsData = new DataTable();
OleDbDataAdapter dbAdapter = new OleDbDataAdapter("select * from [Filters$B2]", connExcel);
dbAdapter.Fill(xlsData);
//Now i want to see that value in xlsData???? or possibly convert it since it is only one cell loaded to a string? HELP?

Hi vkid,
>>All there is in my datatable is one value loaded. Here's my code, but how do i convert that datatable to a string?
About convert datatable to a string, you can use the following code
string res = String.Join(Environment.NewLine, table.Rows.OfType<DataRow>().Select(x => String.Join(" ; ", x.ItemArray)));
But based on your title, How to get specific cell, please check the following code
string value = table.Rows[0].ItemArray[0].ToString();
It means get the firstrow and first column value. You can get the specified cell which you want.

Strip the first character from a string

i am trying to strip the leftmost character from a string
using the following:
<cfset Charges.DTL_CHG_AMT_EDIT =
#Right(Charges.DTL_CHG_AMT_EDIT,Len(Charges.DTL_CHG_AMT_EDIT)-1)#>
i keep getting the following error:
Parameter 2 of function Right which is now -1 must be a
positive integer

> RemoveChars() much easier than Right()? How so?
Semantically, if the object of the exercise is to *REMOVE
CHARacters from a
string* (which it is, in this case), it is simply better
coding to use
removeChars() rather than right(). That, and it's one less
function call
(the RIGHT() solution also requires a call to LEN() for it to
work).
So removeChars() is "easier" because it reflects the intent
of the exercise
directly, is simpler logic, is easier to read, and - I can't
be arsed
counting keystrokes - is probably less typing.
That'd be how.
