我有一个动态选择的Cell,它将填充一些我将要放置的信息以及当我将信息和 ENTER keypressed 放在该Cell时;
1 - 它应该触发一个宏
'macro(value)
macro1 myinfo
2 - 宏应该获取该单元格中的信息
myinfo = Cells( i, j )
那我该如何实现呢?

要捕获正在按下的特定键,您需要OnKey
方法:
Application.OnKey "~", "myMacro" ' for the regular enter key
' or if you want Enter from the numeric keypad:
' Application.OnKey "{ENTER}", "myMacro"
' Below I'll just assume you want the latter.
以上说,当按下 Enter 键时必须运行myMacro
。 OnKey
方法只需要调用一次。你可以把它放在Workbook_Open
事件中:
Private Sub Workbook_Open()
Application.OnKey "{ENTER}", "myMacro"
End Sub
要停止捕获 Enter 键,
Application.OnKey "{ENTER}"
要检查在单元格A1上是否按下了 Enter ,您可以这样做:
Sub myMacro()
If Not Intersect(Selection, Range("A1")) Is Nothing Then
' equivalent to but more flexible and robust than
'If Selection.Address = "$A$1" Then
MsgBox "You pressed Enter while on cell A1."
End If
End Sub
现在要检测是否仅在特定单元中按下了 Enter ,只有该单元格已被编辑,我们必须有点聪明。假设您编辑一个单元格值并按Enter键。触发的第一件事是OnKey
宏,然后触发Worksheet_Change
事件。因此,您首先必须“保存OnKey
的结果”,然后根据这些结果处理Worksheet_Change
事件。
像这样发起OnKey
:Application.OnKey "{ENTER}", "recordEnterKeypress"
在您的代码模块中,您将拥有:
Public enterWasPressed As Boolean
Sub recordEnterKeypress()
enterWasPressed = True
End Sub
Worksheet_Change
事件将捕获单元格编辑:
Private Sub Worksheet_Change(ByVal Target As Range)
If enterWasPressed _
And Not Intersect(Target, Range("A1")) Is Nothing Then
MsgBox "You just modified cell A1 and pressed Enter."
End If
enterWasPressed = False 'reset it
End Sub
现在,上面的代码完成了你在问题中提出的问题,但我想重申一下:你的问题听起来非常像XY problem。为什么要检测按下的 Enter 键?让我们知道,也许我们可以建议替代方案。

导致在该单元格中输入股票代码并在excel中提供该股票的信息并且Worksheet_Change或更改命令只会导致它进入循环时导致错误启动宏导致当股票信息被解析到单元格中时将一次又一次地触发改变事件.. - BerkerYüceer31分钟前
的Berker,
为此,您无需捕获“ENTER”键。比方说,您键入股票代码,而不是按ENTER键,您单击另一个单元格。您是否也不希望在该场景中触发宏?如果是,请尝试下面的代码。我假设在单元格A1中输入股票代码时必须运行宏。
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo Whoa
With Application
.ScreenUpdating = False
.EnableEvents = False
End With
'~~> This line ensure that the code will enter into the
'~~> block only if the change happened in Cell A1
If Not Intersect(Target, Range("A1")) Is Nothing Then
Application.EnableEvents = False
'
' ~~> Put your macro code here or run your macro here
'
End If
LetsContinue:
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
Exit Sub
Whoa:
MsgBox Err.Description
Resume LetsContinue
End Sub
编辑:我看到您已经选择了答案:)

使用工作表更改事件;
如下所示,
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$1" Then
' call your sub
End If
End Sub
将此代码放在相应的工作表模块中。

非常感谢这一点,我会对其进行更改,如下所示:
Dim oldvalue As String Dim newvalue As String Private Sub Worksheet_Change(ByVal Target As Range) On Error GoTo Whoa
With Application
.ScreenUpdating = False
.EnableEvents = False
End With
'~~> This line ensure that the code will enter into the
'~~> block only if the change happened in Cell A1
If Not Intersect(Target, Range("A:D")) Is Nothing Then
Application.EnableEvents = False
'
' ~~> Put your macro code here or run your macro here
'
oldvalue = Range(Target.Address).Value
Range(Target.Address).Value = Range(Target.Address).Value * 2.33
newvalue = Range(Target.Address).Value
MsgBox ("value changed from " & oldvalue & " to " & newvalue)
End If
LetsContinue: 随着应用 .ScreenUpdating = True .EnableEvents = True
结束Exit Sub
哇: MsgBox Err.Description 继续LetsContinue 结束子
这将使您有机会将范围内的任何单元格更改为特定值(我希望在单元格值更改后将单元格值乘以因子,并向我显示将给出旧值和新值的消息,
欢呼声 祝你好运
