System.Windows.Controls.TextBox 句柄

System.Windows.Controls.TextBox Handle(System.Windows.Controls.TextBox 句柄)

问题描述

我觉得我在这里遗漏了一些非常明显的东西.

I feel like I'm missing something really obvious here.

我知道表单通常具有 Handle 属性，但我使用的是 System.Windows.Controls.TextBox 并且它没有 Handle 属性.

I know that forms in general have a Handle property, but I am using a System.Windows.Controls.TextBox and it does not have a Handle property.

如何访问 TextBox 的句柄?我注意到 RichTextBox 具有 Handle 属性，那么为什么不是常规的 TextBox?

How do I access the TextBox's handle? I noticed that RichTextBox has the Handle property, so why not the regular TextBox?

推荐答案

你可以调用 句柄 在文本框上.它是从 System.Windows.Forms.Control 继承的属性.

You can just call Handle on the TextBox. It is an inherited property from System.Windows.Forms.Control.

问题已更新为询问 WPF

WPF 不像典型的 Win32 应用程序或 WinForms 应用程序那样使用句柄.每个控件在 WPF 中都不是它自己的窗口.您可以使用 Spy++ 验证这一点，它无法区分每个控件.因此，您不能像使用 WinForms 和 Win32 应用程序那样向单个控件发送消息.

WPF doesn't use handles like a typical Win32 application or WinForms application. Each control is not its own Window in WPF. You can verify this with Spy++, it cannot differentiate between each control. Therefore you cannot SendMessage to the individual controls like you can with WinForms and Win32 apps.

您可以使用 WindowInteropHelper 来获取WPF 窗口的父窗口句柄.

You can use WindowInteropHelper to get the parent window handle of a WPF window.
