英文:
trying to change the focus change button from tab to enter in c# windows forms
问题
以下是翻译好的部分：
"所以如标题所述，我试图将标签按钮更改为回车按钮。我已经写了这个代码，它有点起作用，但当在按钮上按下回车时，它会触发按钮而不是改变焦点。每次按回车键时都会播放声音。如何禁用回车键功能？"
英文:
so as the title says im trying to change the tab button into enter button. i wrote this already and it kinda works
public class EnterBasedForm : System.Windows.Forms.Form
{
public EnterBasedForm()
{
KeyPreview = true;
KeyUp += new KeyEventHandler(OnKeyPressed);
}
public void OnKeyPressed(object? sender, KeyEventArgs handler)
{
if (handler.KeyCode == Keys.Enter)
{
SendKeys.Send("{TAB}");
}
}
}
but when getting on a button this presses the button instead of changing the focus. and each time pressing enter it plays a sound. how can i disable the enter key functionallity?

你可以在 ProcessCmdKey() 中捕获回车键，使用 base.ProcessTabKey() 强制生成一个制表键，然后通过返回 true 来消耗回车键，以防止它继续传递：
public partial class EnterBasedForm : Form
{
public EnterBasedForm()
{
InitializeComponent();
}
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.Enter)
{
base.ProcessTabKey(true);
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
}
英文:
You can capture the Enter key in ProcessCmdKey(), force a Tab key with base.ProcessTabKey(), and then consume the Enter key so it doesn't go further by returning true:
public partial class EnterBasedForm : Form
{
public EnterBasedForm()
{
InitializeComponent();
}
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.Enter)
{
base.ProcessTabKey(true);
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
}
