如何使用c#禁用Alt + Shift + Tab?
问题描述:
如何禁用备选 + ⇧Shift + ↹Tab使用c#?我已经禁用了Alt + ↹Tab使用一个只有两个参数的函数。但要禁用三键键盘?如何使用c#禁用Alt + Shift + Tab?
我任何人都需要我的代码来禁用两个按键组合,我凸轮发布。但它相当大。
要禁用Alt键 + ↹Tab我这样做,
RegisterGlobalHotKey(Keys.Tab, USE_ALT);
如何通过三个参数[Alt键,Shift键,Tab]键?

答
你提到你使用的函数需要2个参数,但你没有提到它是哪个函数。在任何情况下,Keys.Shift
和Keys.Alt
都是修饰键,所以无论您传递“Alt”到您的位置,都可能需要按位或按住“Shift”。
在WPF中,这将是这样的:
var altShift = Keys.Alt | Keys.Shift;
你为什么要? Win + Tab,Alt + Esc,Alt + Shift + Esc,Ctrl + Esc,Ctrl + Pause,Win + D,Win + M,...太? (记录:我怀疑你想要一个自助服务终端应用程序,防止用户做任何事情离开应用程序。)在这种情况下,我建议你不要给用户一个键盘。 – Joey 2010-05-20 07:08:08
这是一个很好的:) – Anuya 2010-05-20 07:13:05
是这样的: var TabShift = Keys.Tab | Keys.Shift; RegisterGlobalHotKey(TabShift,USE_ALT); – Anuya 2010-05-20 07:58:29
