将变量绑定到 Powershell 中的组合框和文本框答案

【问题标题】：Bind variables to combobox and textbox in Powershell将变量绑定到 Powershell 中的组合框和文本框
【发布时间】：2021-01-01 06:39:41
【问题描述】：

我会给你带来更多问题。

我已经构建了一个简单的 GUI 来创建打印机或更改打印服务器上的驱动程序。但是，当我单击 RUN 按钮时，它不会做任何事情，只是弹出操作成功的消息。有人可以帮我检查代码并告诉我我做错了什么吗？

我还想将模型选择链接到另一个名为“模型”的变量，该变量将使用模型的快捷方式来部署一些特定设置，一旦弹出“操作成功消息”并按下“确定”，所有组合框和 texbox重置为空白。

仅供参考：PortCreation、PrinterCreation、ChangeDriver 和 ApplyConfigLexmark 是在 Powershell 中执行代码的函数，所以我不会放整个代码。我使用的变量如下：

$maker # choose the brand of the physical device
$model # short name of the device model
$modelfull # Full device model
$tray # number of the trays the device has
$driver # Driver name
$PQ # print queue name
$server # hostname of the server
$hostname # hostname of the printer
$location # location of the device

检查我的更新答案，如果有帮助或有任何问题，请告诉我

【解决方案1】：

我测试了您的代码并更改了这一行以显示制造商并且它可以工作。为什么说变量没有绑定？

[System.Windows.MessageBox]::Show('Operation completed!' + $maker)

Also Checked 应该是 IsChecked

if ($RadioCreate.IsChecked -eq $true){

【讨论】：

嗨@Hassan，当我按下运行按钮时，程序什么也没做，甚至没有启动创建打印队列的过程。我已经挣扎了很长时间，老实说，我不知道我还能做些什么来让它发挥作用
更新。它正在工作，但只有创作部分:) 我会弄清楚为什么另一部分不工作。现在我需要添加更多 MessageBox 以使其与用户更具交互性。非常感谢！
@Menistro 太好了，我的回答有帮助吗？
