将button1作为窗体的缺省命令按钮吧：

button1.default=true

如果没有上面这种用法，试试

Me.AcceptButton=button1

利用VB.NET怎样使窗体在没有焦点时也能检测键盘事件？

窗体内检测按键

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Me.KeyPreview = True '注册窗体的键盘事件

End Sub

在TextBox1中显示按键代码

Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown

TextBox1.Text = Str(e.KeyCode) + vbCrLf

End Sub

窗体没有焦点，用窗体监测键盘输入缓冲区可以解决，但这似乎可以用于监测用户输入内容，不要用于非法目的呀！所以就是知道也不会告诉你的。

vb点虐 在for循环中如何获取键盘按键

Public Sub TextBox_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)

Dim SplitStr As String = ","

Dim SelectionStart As Integer = sender.SelectionStart

Dim TextLength As Integer = sender.Text.Length

'------------------------------------------------------------------

Select Case Asc(e.KeyChar)

Case Is = 8 '"回删"

Dim str As String = sender.text

Dim Array = Split(sender.text, ",", -1)

If sender.SelectionStart = str.Length Then

If str.Contains(",") Then

Dim text = ""

For x = 0 To UBound(Array) - 1

If text = "" Then

text += Array(x)

Else

text += "," + Array(x)

End If

Next

sender.text = text

sender.SelectionStart = text.Length

e.KeyChar = Chr(0)

End If

End If

Case Asc("0") To Asc("9") '" 0 to 9 "

e.KeyChar = e.KeyChar

Case Is = 44, 45 '","

Select Case TextLength

Case Is = 0

e.KeyChar = Chr(0)

Case Else

Select Case SelectionStart

Case 0

e.KeyChar = Chr(0)

Case 1 To TextLength - 1

If Mid(sender.text, SelectionStart, 1) = SplitStr Or Mid(sender.text, SelectionStart + 1, 1) = SplitStr Then

e.KeyChar = Chr(0)

Else

e.KeyChar = e.KeyChar

End If

Case TextLength

If Mid(sender.text, SelectionStart, 1) = SplitStr Then

e.KeyChar = Chr(0)

Else

e.KeyChar = e.KeyChar

End If

End Select

End Select

Case Else

e.KeyChar = Chr(0)

End Select

End Sub

这是我的程序中复制过来的,只能输入数据字与逗号还有下划线,你查一下F和J的Ass吗是多少,改写一下就OK
