问题 I am trying to drop users from a SQL server database via PowerShell using the following code: $sql_server = "mysqlserver" $dbname = "mydb" [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null $server = New-Object ("Microsoft.SqlServer.Management.Smo.Server")($sql_server) $db = $server.Databases["$dbname"] $logins = $db.users if ($logins.count -gt 0) { foreach ($login in $logins) { if ($login -notmatch "\[dbo\]|\[guest\]|\[INFORMATION_SCHEMA\]|\[sys\]") {

问题 What am I missing? I was trying to implement converters to my XAML-based PowerShell script but with no luck. I've picked up pieces of information from sites like StackOverflow. but couldn't find one successful implementation of a converter in powershell XAML-based GUI script. in the code I am testing the converter, and it works (you can see 2 examples for conversion) so that means that powershell itself accepted the new converter type, buy this converter cannot be implemented in my xaml code.

问题 I have a function (actually several instances of this), but there are times that it may return a list of several elements, and there are times that it may return a single element. I want the function to return an array ( [System.Object[]] ) every time so that (on the receiving end), I can always anticipate it being an array and index into it, even if I am just pulling the 0th element. I've tried casting the return type multiple ways (see code below) ... including (for example) return @("asdf"

问题 So I got to say that I m new to using PowerShell for parsing out XML. With that said, how to do I combine multiple -XPath So that I can finishing building out my expression report. Please let me know, I have tried several combinations and none of them seem to work with namespace XML. <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" niaVersion="12.0.0.756" xmlns="http://something.com/something

问题 I am writing a script in powershell, that will wait for a specific event in Windows 7. Event ID 4776, in the Security Log. The script will run when the computer is locked. The script is supposed to run in idle, essentially a while(true) loop, and it will wait for the "Failed Audit" of the event to occur. Once the event happens, it will add one to a counter. Once the event happens in a "Success Audit" status, it will break from the loop and thus be done with the script. My initial idea, was to

问题 On Azure Portal, I am able to setup path-based rules which have some default setting, and a list of sub-rules (UrlPathMap). Each of those sub-rules has a name, paths, backend pool, and HTTP setting that have to be configured. As I can see I can update this map easily through Azure Portal. I want to be able to create such sub-rules dynamically from code as part of the application installation. I would prefer to do this directly from .NET (ASP.NET Core 3.1) application, but Azure CLI or Azure

问题 I have the following variables: [string]$eth_netmask = "ext_netmask" [string]$ext_netmask = "255.255.252.0" $($eth_netmask) is returning ext_netmask . I was expecting 255.255.252.0 What am I doing wrong? Thanks for the help in advance! 回答1: The command $eth_netmask returns the value of the variable named eth_netmask. The expression $(something) has nothing to do with variables, but instead evaluates the contents of the parentheses before evaluating the rest of the statement. That means that

问题 I am using Windows Powershell (on windows 10). I am also using the latest version 2.3.0.5 of docker desktop. When I type "docker version" in powershell the command is not recognized. The error message reads "Der angegebenen Datei ist keine Anwendung zugeordnet." (English: No application is assigned to the specified file). When I instead include the file extension and type "docker.exe version" the command can be executed. The interesting thing is that "docker version" works in a cmd window,

问题 So essentially I'm parsing content from http://www.webcal.fi/en-GB/other_file_formats.php via Invoke-WebRequest and converting this from JSON into a PSObject via the ConvertFrom-Json cmdlet. Now I need to get that data into SQL, and the most effective way I can think of (with the ability to re-use pre-existing functions I have already) is to get this PSObject converted into a Datatable . I can't seem to think of any easy way to achieve this while keeping it generic, I don't want to hard-code
