问题 I was wondering if there is anyway to return the name of the table using a formula? I was working on a way to break down a few thousand addresses into there perspective column of information. ie.. #, Street, City, State, Zip-code and Phone#. The addresses are not in any consistent format that Text to Columns would work. I finally came up with the formulas to get the job done, but the are very long. In a post I found it suggested to use repeated parts of the formulas as a Defined Name. And it

问题 See also: Where in the documentation does it say that while tests readdir for definedness?. ( Not a duplicate; just closely related. ) Many people treat the loop below as idiomatic: while (defined(my $file = readdir($dir)) { ... } instead of: while (my $file = readdir($dir)) { ... } because supposedly with the latter version if the filename is just "0" (zero) it should terminate the loop, whereas it returns 'undef' when there are no more files. However at some point in the past this test for

问题 I have my $dbConnection variable set at the very top of the page. And I have a contact form included on the same page. The contact form works fine. However, when submitting, it gives me an undefined error; that's weird because I'm 199% sure I have the variable set correctly. The form is going through a script. function ubbreplace($text){ if (strpos($text, "[contact-form]") !== false) { ob_start(); include("contactform.php"); $replace = ob_get_contents(); ob_end_clean(); $text = str_replace("

问题 I'm trying to get variables that I defined while in a function from another function I called in that function, example: $thevar = 'undefined'; Blablahblah(); echo $thevar; (should echo blaaah) function Blahedit(){ echo $thevar; (should echo blah) $thevar = 'blaaah'; } function Blablahblah(){ global $thevar; $thevar = 'blah'; Blahedit(); } I want to know if there's another way of doing this without passing down params to Blahedit(), get_defined_vars gives me vars within the function not

问题 So, we have the code: class Foo def bar puts "Before existent: #{(defined? some_variable)}" puts "Before not_existent: #{(defined? nonexistent_variable)}" raise "error" some_variable = 42 rescue puts "exception" ensure puts "Ensure existent: #{(defined? some_variable)}" puts "Ensure not_existent: #{(defined? nonexistent_variable)}" end end And call it from irb: > Foo.new.bar And, that is will return: Before existent: Before not_existent: exception Ensure existent: local-variable Ensure not

问题 I'm looking for a way to access all the Build properties defined while executing MSBuild. I have a configuration file. I want to modify the Properties in the configuration file and copy it to a new location. Is there a way to do it? 回答1: If you run the build with /verbosity:detailed or /verbosity:diagnostic you will get very detailed output of all the properties that was used during your build process. However I suspect you want to change a config type file after/before you copy the builded

问题 I'm new to primefaces and try to realize a simple web-app with jsf. In this app I have a login.xhtml where a user can enter a name and his password.

问题 I have a simple function, which I shall call myFunction . It takes two parameters, performs some calculations on them, and returns the result. I also have a class, MyClass , which has a constructor that has a header like this: __init__(self, bar, fun=myFunction): When I try to run anything in this class, I get the following error: MyClass def __init__(self, bar, fun=myFunction): NameError: name 'myFunction' is not defined If I remove this class, I can use myFun in the Python Shell, so what's
