Powershell - 如何使用下拉菜單進行實時活動目錄搜索

Question

對於像你這樣的有經驗的人來說，這可能是一個簡單的問題，但是我怎樣才能在下拉菜單中爲活動目錄搜索用戶名？結果並將值傳遞給$var

這裏是我和我的兩個下拉菜單，我希望manager下拉列表根據我輸入的字符串在我的Active Directory中執行查找。即如果我輸入Macdonald，則下拉菜單項會在我的AD中顯示所有麥克唐納的名或姓。

要進行實時更新，您需要在保管箱中的文本被修改時更新列表。當您寫入時，至少會觸發2個事件：TextUpdate和KeyPress。選一個。我建議TextUpdate，因爲它在文本被改變之後起作用，而KeyPress之前有反應。您可以添加使用例如爲：

$DropDown2.add_TextUpdate({ Write-Host "TextUpdate. Updated text is: $($Dropdown2.Text)" }) 

在您需要運行查詢DC功能的腳本塊一個事件監聽，但所以這是另外一個問題這個問題並未標ADSI，AD，LDAP等。

請注意這將運行查詢每次您更改一個字母，這會導致額外的DC負載。例如。如果你想寫「馬克」，它會搜索至少4次，然後再寫完。

我建議使用帶有搜索按鈕的文本框來代替，以儘量減少不必要的流量。
