vba - 错误时为变量赋值

Question

我想要做的是，如果出现错误，某些值会被重置。就像是:

Dim r As Integer
Dim feeder As String
Dim origen As String

On Error GoTo errhandler:
For j=1 to 100
   r = Evaluate("=MATCH(1, (C:C=""" & feeder & """) * (D:D=""" & origen & """),0)")
Next j

Exit Sub

errhandler:
r = 0
End Sub

但是我如何强制它回到 For如果有错误？

Answer 1

您可以使用 IsError 来设置 r 的值，而不是 ErrHanlding关于错误:

Sub t1()
  Dim feeder As String
  Dim origen As String
  For j = 1 To 100
   Dim r As Variant
   If IsError(Evaluate("=MATCH(1, (C:C=""" & feeder & """) * (D:D=""" & origen & """),0)")) Then
    r = 0
   Else
    r = Evaluate("=MATCH(1, (C:C=""" & feeder & """) * (D:D=""" & origen & """),0)")
   End If
  Debug.Print r ' Just for you to check
 Next

End Sub
