推荐答案

一个经常被问到的问题...
参见此处 [

A question asked often...
See Here[^]

For Key Chars

for(int i=1; i<=255; i++)
{
char cs=(char) i;
Response.Write(i.ToString() + "--");
Response.Write(cs.ToString() + "<br>");
}

在设计视图中，选择您的Form并转到其属性.选择事件"，然后双击"KeyUp".这将为您添加一个事件处理程序.

添加此代码:

In the design view select your Form and go to it''s properties. Select "events" and double click "KeyUp". This will add a event handler for you.

Add this code:

If e.Control = True And e.KeyCode = Keys.N Then
   MsgBox("whatever")
End If

希望对您有所帮助:)

Hope this helps :)

您可以在keydown事件中获取它.

You can get it in keydown event.

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
  If e.KeyCode = Keys.N And e.Control Then
    MessageBox.Show("Ctrl+N is pressed", "Access Keys")
  End If
End Sub

对于空表单，此代码可以，但是在带有控件的表单中，请不要忘记将表单的KeyPreview属性设置为true.

For empty form this code is OK, but in form with controls, don''t forget to set KeyPreview property of form to true.

KeyPreview = True
