Powershell组合框项目可变 [英] powershell combobox items to variable

问题描述

我正在尝试使用Gui创建一个powershell脚本，该GUI为用户提供了可用驱动器的下拉列表，然后当用户选择驱动器并单击确定"时，该脚本将驱动器映射为M:\但是我无法解决如何将组合框中的所选项目传递到变量$ MapDrive

I am trying to create a powershell Script with a Gui that gives the user a drop list of available drives and then when the user selects the drive and clicks ok the script maps that drive as M:\ But I cant work out how to get the selected item in the combo box to be passed into the variable $MapDrive

#List of Drives To Map
$DriveList = @("0.  DGL_Data","1.  P1","2.  DGLFSG3","3.  p3 (TPC)","4.  p4","6.  p6","7.  p7","8.  p8","9.  p9","10. p10","11. p11","12. p12")
#Displays With Drive to Map
$MapDrive = convert.ToString($Dropdown.SelectedItem)

Function MapDrive {

If ($MapDrive -eq $DriveList[0]){
Write-Output Sucess > "C:\Users\andy.burton\Desktop\Practice Selector\Success.txt"}

ElseIf ($MapDrive -eq $DriveList[1]){
Write-Output BooYah > "C:\Users\andy.burton\Desktop\Practice Selector\Yes.txt"
}

Else {
Write-Output Failure > "C:\Users\andy.burton\Desktop\Practice Selector\Failed.txt"}
}

#test Function 
Function test {
Write-Output $MapDrive > "C:\Users\andy.burton\Desktop\Practice Selector\Success.txt"
}

 GenerateForm

我也想隐藏powershell窗口，而不是我尝试过的gui -hiddenwindow隐藏了，但隐藏了所有内容

I also want to hide the powershell window but not the gui I have tried -window hidden but that hid everything

推荐答案

ComboBox具有几个事件，您可以将其绑定到其中，这些事件可以完成各种操作.事件之一是SelectedIndexChanged.您可以将该事件添加到ComboBox对象中，并更新 $ MapDrive

The ComboBox has several events that you can tie into that will do various things. One of the events is a SelectedIndexChanged. You can add that event to your ComboBox object and update $MapDrive

此代码 $ MapDrive = convert.ToString($ Dropdown.SelectedItem)在初始编译期间仅触发一次.在运行时进行编译后，必须使用事件来触发代码更改.

This code $MapDrive = convert.ToString($Dropdown.SelectedItem) will only fire once during the initial compile. You have to use events to trigger code changes after compile during runtime.

此外，在Powershell中，您可以使用以下命令.gm 以获得对象的方法和属性的列表.您可以使用 [System.Windows.Forms.checkedlistbox] .GetEvents()来获取对象的事件列表.

Also, in Powershell you can use the following command [System.Windows.Forms.ComboBox] | gm to get a list of the methods, and properties of the object. You can use [System.Windows.Forms.checkedlistbox].GetEvents() to get a list of events of an object.
