问题 I've configured winrm on all my desktops via GPO, so I can now use the invoke-command cmdlet to run commands locally on remote machines. When I run net localgroup administrators on my local machine this works and gives me what I want. The problem is I cannot do anything with this data. I cannot pipe out the results to a variable so I can lets say remove specific accounts. Is there a built in cmdlet that will let me do the same as net localgroup administrators ? 回答1: While it's possible to run

问题 I want to convert a Joda Time UTC DateTime object to local time. Here's a laborious way to do it which seems to work. But there must be a better way. Here's the code (in Scala) without surrounding declarations: val dtUTC = new DateTime("2010-10-28T04:00") println("dtUTC = " + dtUTC) val dtLocal = timestampLocal(dtUTC) println("local = " + dtLocal) def timestampLocal(dtUTC: DateTime): String = { // This is a laborious way to convert from UTC to local. There must be a better way. val instantUTC

问题 I am trying to define and initialize a MySQL variable for a query. I have the following: declare @countTotal int; SET @countTotal = select COUNT(*) from nGrams; I am using MySQL in Netbeans and it tells me I have an error. What/where is my error? How can I fix this? 回答1: MySQL has two different types of variable: local variables (which are not prefixed by @ ) are strongly typed and scoped to the stored program block in which they are declared. Note that, as documented under DECLARE Syntax:

问题 e.g. x = 123 p = Proc.new { x = 'I do not want change the value of the outer x, I want to create a local x' } In Ruby Is there something the same as "my" keyword in Perl ? 回答1: As per the Perl documentation of my,I think you are looking for something like below in Ruby:- x = 123 p = Proc.new {|;x| x = 'I do not want change the value of the outer x, I want to create a local x' } p.call # => "I do not want change the value of the outer x, I want to create a local x" x # => 123 回答2: Beware!

问题 I have a folder that is my animation/game, and in the folder is the .pyw file and a .wav music file. I have import wave wave.open() and I don't know what to put in the parenthesis. I know it is supposed to be the filename, but someone might install the game in an unknown directory. How do I access the local folder through the filename? The files are in the same folder, and the music is named "Music.wav". 回答1: A common way this is done is by using the path of the current module, which is

问题 Consider the following method: void a () { int x; boolean b = false; if (Math.random() < 0.5) { x = 0; b = true; } if (b) x++; } On x++ I get the "Local variable may not have been initialized" error. Clearly x will never be used uninitialized. Is there any way to suppress the warning except by initializing x? Thanks. 回答1: No, there is no way Java can examine all possible code paths for a program to determine if a variable has been initialized or not, so it takes the safe route and warns you.

问题 I am writing a C# application that uses Local DataSets. I have a DataSet for Customer Information, and a DataSet for Stocked Items. In regards to perfomance, and file size, would it be advisable to use just one DataSet with the Customer Infomation and the Stocked Items DataTables, or separate DataSets for each DataTable? I intend to use data to put into a report (using report viewer). 回答1: The DataSet is built for, well just that, a set of data. It's built to allow you to create relationships
