检测键盘输入 [英] Detect keyboard input

问题描述

大家好，



我刚刚开始实施与usb键盘集成的winform。我尝试在互联网上搜索，但我没有找到任何成功的键盘输入。



如果你们有建议，我需要指导完整的构建应用程序与USB集成键盘，从导入，声明和keydown值开始。我希望有人能为我提供指南的链接。也许我在搜索引擎中搜索措辞时错了。 TQ



从下面的评论中复制的其他信息

我为此处提出一个混淆问题而道歉。实际上我使用WinForm for VB.net 2010创建了一个简单的程序，当我按下键盘上的某个键时，它会执行刷新列表视图（F5），取消输入（Esc），保存（Ctrl + S）等操作。 。我这个集成意味着我需要指定按哪个键来执行前面所述的特定操作。我假设我将使用键盘执行所有这些功能而不是鼠标点击。我不想使用Alt + XXXX，我可以把它放在按钮功能上，字符上有_（如果你有我的意思）

解决方案

假设键盘是一个标准设备，它根本不需要你的工作，除非你想捕获一些击键组合并在你的应用程序中将它们用作热键。

键盘被处理通过操作系统，只需通过正常事件传递数据，无论是PS /还是USB，无论您是否插入一个，两个或七个物理键盘。我经常连接两个键盘时间（对于不同的布局/语言），它完全按照您的预期 - 无缝地工作。

所以你想要简单的快捷方式。

首先，如果您使用按钮快捷方式可用性是默认的。只需在文本中添加一个放大器： Button1.Text =& Ok; ，并且您有Alt + O作为快捷方式（但是你没有出于某种原因想要这个）。有了菜单，你有更多的可能性，请看这里： http://msdn.microsoft.com/en-us/library/system.windows.forms.menuitem.shortcut(v = vs.110）.aspx [ ^ ] 。如果您希望有更通用的方法来为自定义操作添加自定义快捷方式，可以在此处查看： http：// snipplr .com / view / 57156 / [ ^ ]。

additional information copied from comment below
I apologize for making a confuse question here. Actually I create a simple program using WinForm for VB.net 2010 which when I press a certain key on keyboard, it will perform action such as refresh listview(F5),cancel input (Esc),saving (Ctrl+S) and so on. I guest this integrate mean I need to specify which key is press to perform specific action as stated before. I assume that I will perform all those function using keyboard not by mouse to click. I dont want to use the Alt + XXXX where I can put it on the button function with the _ on the character (if you got what I mean)

解决方案

Assuming that the keyboard is a standard device, then it needs no work on your part at all, unless you want to capture some keystroke combinations and use them as "hotkeys" in your application.
A keyboard is handled by the OS and just passes data through via the normal events, regardless of whether it is PS/" or USB, and regardless of whether you have one, two or seven physical keyboards plugged in. I have often had two keyboards connected at the same time (for different layout/languages) and it all works exactly as you would expect - seamlessly.

So you want simple shortcuts.
First of all, if you use buttons shortcut availability is default. Simply put an amp in the text: Button1.Text = "&Ok"; , and you have Alt+O as shortcut (but you don't want this for some reason). With menus, you have even more possibilities, see here: http://msdn.microsoft.com/en-us/library/system.windows.forms.menuitem.shortcut(v=vs.110).aspx[^]. If you want to have more general approach to be able to add custom shortcuts to custom actions, you can have a look here: http://snipplr.com/view/57156/[^].
