vba - VBA 出错时如何从函数返回

Question

我是 VBA 新手，希望在看到错误时从函数返回。无法这样做。有什么指点吗？

Function GetEditboxValue(control As IRibbonControl, text As String) As String

    If Not IsMissing(text) Then
        If Not IsNumeric(text) Then
            MsgBox "Please enter numeric value only."
            ' I WANT TO RETURN HERE 
        End If
    End If


    If control.id = "xyz" Then
    spaceAboveTable = text
    End If


End Function

您需要将 EXIT FUNCTION 放在那里以退出进一步执行:

Function GetEditboxValue(control As IRibbonControl, text As String) As String

    If Not IsMissing(text) Then
        If Not IsNumeric(text) Then
            MsgBox "Please enter numeric value only."
            EXIT FUNCTION
        End If
    End If


    If control.id = "xyz" Then
    spaceAboveTable = text
    End If


End Function
