vb调试模式下按键查看表达式的值

VB在窗体中显示按下键盘按键的字母可以通过Form_KeyDown获取按键的KeyCode，然后再把KeyCode转换为相应的键的名字。

代码如下：

Private Sub Form_Load()

MeKeyPreview = True '使窗体可以获取键盘事件

End Sub

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

Print KeyCodeToStr(KeyCode) '获取按键信息

End Sub

Public Function KeyCodeToStr(vbKeycode As Integer) '按键的KeyCode转为相应键盘键

If vbKeycode > 47 And vbKeycode < 91 Then

KeyCodeToStr = Chr(vbKeycode)

Exit Function

ElseIf vbKeycode > 111 And vbKeycode < 124 Then

KeyCodeToStr = "F" & vbKeycode - 111

Exit Function

End If

Select Case vbKeycode

Case 8: KeyCodeToStr = "Back"
