如何使用c＃禁用Alt + Shift + Tab？

Question

如何禁用備選 + ⇧Shift + ↹Tab使用c＃？我已經禁用了Alt + ↹Tab使用一個只有兩個參數的函數。但要禁用三鍵鍵盤？

我任何人都需要我的代碼來禁用兩個按鍵組合，我凸輪發布。但它相當大。

要禁用Alt鍵 + ↹Tab我這樣做，

RegisterGlobalHotKey(Keys.Tab, USE_ALT); 

如何通過三個參數[Alt鍵，Shift鍵，Tab]鍵？

Answer 1

你提到你使用的函數需要2個參數，但你沒有提到它是哪個函數。在任何情況下，Keys.Shift和Keys.Alt都是修飾鍵，所以無論您傳遞「Alt」到您的位置，都可能需要按位或按住「Shift」。

在WPF中，這將是這樣的：

var altShift = Keys.Alt | Keys.Shift;
