hi,
In my application i write the code like this
byte [] byt=new byte[ Convert.ToSbyte(textbox1.tex)];
it is giving the error that input string was not in a correct format.
Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this?
BTW, the query should return a single value.
select distinct ColumnA from
(
select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX'
)
where len_rank <= 1
Thank you.
i need the code to convert the string type data into integer type data if i have entered a numerical value in the text box.
i am using visual c++ windows forms and the visual studio
I need to use preg_match to check that only a-z0-9. is used (including full stop(.)). I don't want to replace anything. My problem is that it doesn't notice white space at beginning of a string.
Also, if anyone knows how to check there is no two full stops in a row, I would be very grateful.
What I have so far:
("/[^a-z0-9.]+$/",$request)
Thanks !
Hello!
How can I draw a String in Java (using Graphics2d) in monospace mode? I have a font that looks like LCD screen font, and I want to draw something like LCD label.
I am using Digital 7 Mono font.
Do you know where I can find another font that will be monospace and lcd (I wan to type only digitals)?
I am reading a file by line and need to extract latitude and longitude from it.
This how lines can looks:
DE 83543 Rott am Inn Bayern BY Oberbayern Landkreis Rosenheim 47.983 12.1278
DE 21147 Hamburg Hamburg HH Kreisfreie Stadt Hamburg 53.55 10
What's for sure is, there are no dots surrounded by digits except for the ones representing the doubles.
Unfortunately there are Values without a dot, so it's probably best to check for numbers from the end of the String.
thanks for your help!
Must I do something like this?
NSString *errorDescription = [error localizedDescription];
NSString *errorInfoStr = NSLocalizedString(errorDescription, nil);
Or do I use NSLocalizedString already when populating the userInfo dictionary with the NSLocalizedDescriptionKey key and value? So the value for that is not actually a key for NSLocalizedString, but it is the actual localized string ready to show up on screen?

How do I find if a string contains html data or not? (note: user provides input via rich:editor and its quite possible he could have used either a simple text or used html formatting)
I have 4 numeric up down controls on a form. They are set to hexidecimal, maximum 255, so they'll each have values from 0 to FF. I'd like to concatenate these values into a string for a textbox.
hi,
how can find position of a character in a string, and get the substring till that character.
say
char* test = "Hello world, I come back";
I want to find first occurrence 'l' character.
I have a string of HTML stored in a database. Unfortunately it contains characters such as ®
I want to replace these characters by their HTML equivalent, either in the DB itself or using a Find Replace in my Python / Django code.
Any suggestions on how I can do this?
Not sure whats going on here, or what could be the integer in this case. Here's the code:
def build_array_from_file(filename)
contents = []
File.read(File.expand_path('lib/project_euler/' + filename), 'r') do |file|
while line = file.get
contents << line
end
end
contents
end
filename is a string and I've checked to make sure the path comes up valid.
Any thoughts? Thanks.
I am a beginner Java programmer. I am attempting to make a simple text editor. I have got the text from the text field into a variable that's a String, called "text".

Thank you!
I need to verify that the provided string has only allowed characters using Oracle regular expressions (REGEXP_LIKE).
Allowed chars are: abcdefghijklmnopqrstuvwxyz0123456789_-.
Trying to execute
SELECT CASE
WHEN REGEXP_LIKE('abcdefghijklmnopqrstuvwxyz0123456789_-.'
, '^[a-z0-9_\-\.]+$')
THEN 'true'
ELSE 'false'
END tmp
FROM dual;
results in 'false'.
Any ideas on this?

It seems that if there is a sql memory leak somewhere and you dont have time to find it you can use the load balance timeout option in a sql connection string to destory the connection after x seconds.
Am i right in assuming I can set the load balance time out to 30-40 seconds and then hunt for the leak latter, while in the mean time the leak will not affect my application too much.
