I have street name as KRZYWON ANIELI and so what should be my regex to allow this kind of expression. Currently I have simple one which uses /^[a-zA-Z ]+$/
Kindly advise.
For what x is
The expression x IS NOT NULL is not equal to NOT(x IS NULL), as is the case in 2VL
(quote from this answer, which is quoting Fabian Pascal Practical Issues in Database Management - A Reference for the Thinking Practitioner -- near the end of that answer)
My guess is when x IS NULL is NULL, but I cannot guess when that would be (i.e. I haven't checked the SQL standard).
I have an InfoPath 2007 browser-enabled form that has a datasource with three columns, let's say columns A, B, and C. I have a dropdown that is keyed to column A and displays column B. Column C contains some data that I want to display in an expression box, and that I also want to use in some data validation against another field on the form. I'm looking for some help on how to reference that column C for displaying and use in validation. Thanks!
What are the limits of writing a C# app when you want a truly impressive GUI? At what point does one have to leave Visual C# behind and go into WPF?
Also, if I choose to go with WPF, do I have to ditch the Visual Studio IDE and go with Expression Studio?
I want ot draw a line the full width of the page in SSRS.
If I could get the page width in (say) px, I could assign it as an expression to the line width. Is this possible? How? Or is there an alternative?
The first definition below produces the warning in the title when compiled with f# 3.0 and the warning level set to 5. The second definition compiles cleanly. I wondered if someone could please explain just what the compiler worries I might accidentally mutate, or how would splitting the expression with a let clause help avoid that. Many thanks.
let ticks_with_warning () : int64 =
System.DateTime.Now.Ticks
let ticks_clean () : int64 =
let t = System.DateTime.Now
t.Ticks
I am new to PHP and regular expression. I was going thorugh some online examples and came with this example:
<?php
echo preg_replace_callback('~-([a-z])~', function ($match) {
return strtoupper($match[1]);
}, 'hello-world');
// outputs helloWorld
?>
in php.net but to my surprise it does not work and keep getting error:
PHP Parse error: parse error, unexpected T_FUNCTION
Why get error ?
I added following line of code in .vimrc
let g:jslint_status = 'enabled'
if exists("jslint_status")
echo jstlint_status
else
echo 'not found'
endif
Error message
E121: Undefined variable: jstlint_status
E15: Invalid expression: jstlint_status
What am I doing wrong?
I am trying to sort the following table:
hYear hSale
------------------------------------
[year] =Count(Fields!sale.Value)
The table only has one row group (year) and no column group.
I'd like to:
-initially sort the table based on the calculated value; is it possible?
-add interactive sort to calculated column based on the value. I assume I should sort 'Detail rows', but what will be the sort expression?
Hi.
I want to retrieve all hashtags from a tweet using a PHP function.
I know someone asked a similar question here, but there is no hint how exactly to implement this in PHP. Since I'm not very familiar with regular expressions, don't know how to write a function that returns an array of all hashtags in a tweet.
So how do I do this, using the following regular expression:
#\S*\w
I have Perl code:
my $s = "The+quick+brown+fox+jumps+over+the+lazy+dog+that+is+my+dog";
I want to replace every + with space and dog with cat.
I have this regular expression:
$s =~ s/\+(.*)dog/ ${1}cat/g;
But, it only matches the first occurrence of + and last dog.
What's the best regular expression for integer separated by comma? It can also contain space between comma, and the field is not required which means it could be blank.
123,98549
43446
etc..
I need an expression to capture a string like this
"A"[A string that is NOT atleast 5 and atmost 6 digits]"B", In other words capture anything that is NOT the following
A[0-9][0-9][0-9][0-9][0-9]B
A[0-9][0-9][0-9][0-9][0-9][0-9]B
I have tried the negative look ahead
regex = "a((?![0-9]{5,6}).)*d" ;
But it fails to capture all scenarios.
Please help

How do I restrict a string to whitelisted characters?
// "HOW am I to understand; this is, BAD"
$str = restrictTo($str,"0-9a-z,. ");
// " am I to understand this is, "
Is there an inbuilt function in PHP that does something close? I can't formulate a regular expression for this though :(
Hi, all.
I'm trying to convert an all-uppercase string in Ruby into a lower case one, but with each word's first character being upper case. Example:
convert "MY STRING HERE" to "My String Here".
I know I can use the .downcase method, but that would make everything lower case ("my string here"). I'm scanning all lines in a file and doing this change, so is there a regular expression I can use through ruby to achieve this?
Thanks!
I just had to write the most redonkulous expression in an SSIS Derived Column to get dates formatted like "01-JAN-2010". It lookes like this:
There's got to be a better way... isn't there?
Class<? extends Algorithm> alg = AlgorithmAllFrom9AndLastFrom10Impl.class
Constructor<Algorithm> c = alg.getConstructors()[0];
For "alg.getConstructors()[0];" I am getting a warning in eclipse
Type safety: The expression of type
Constructor needs unchecked conversion
to conform to Constructor
How do I fix this?
I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code:
var url = document.getElementById("editorURL").value;
if(/(file|http).*/.test(url)) {
}
Maybe someone has a link to an article that explains this a bit more in-depth?
Sorry for this english related question but I only came across that expression in the context of IT. What does abstracting over something mean ? For example abstracting over objects or abstracting over classes.
Thanks
static void Main()
{
string[] a = { "a", "asd", "bdfsd", "we" };
a = a.OrderBy(fun).ToArray();
}
private static int fun(string s)
{
return s.Length;
}
its is giving compile time error . I know that we can do this with Lambda expression like this. a.OrderBy(s=>s.Length).ToArray(); but i want to this do by defining different function . What mistake i have done?
Why I can't construct large tuples in Haskell? Why there's a tuple size limit?
Prelude> (1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1)
<interactive>:1:0:
No instance for (Show
(t,
t1,
t2,
...
t23))
arising from a use of `print' at <interactive>:1:0-48
Possible fix:
add an instance declaration for
(Show
(t,
t1,
t2,
...
t23))

I have a custom control I created from a expression design I created and exported to xaml. I have put in it a bound itemtemplate/datatemplate of a ListBox contorl. It doesn't seem to be rendering more than once and/or it is rendering each item in the same place(kind of like the same x,y coordinates.
hey,
I have two-dimension array
List<List<int>> boardArray
How can I enumerate throw this array to check that it contains other value than 0 ?
I think about boardArray.Contains and ForEach ,cause it return bool value but I don't have too much experience with lambda expression :/
Please help :)
I need to know if the List I am working with contains only some specific values.
var list = new List<string> { "First", "Second", "Third" };
If I want to know if the List contain at least one item with the value "First" I use the Any keyword:
var result = list.Any(l => l == "First");
But how I can write a Linq expression that will return true/false only if the List contains "First" and "Second" values?
