如何在VBa中使用Vlookup？

Question

這是我編寫的在Vba中使用Vlookup的代碼，但我不斷

運行時錯誤1004無法獲取工作表函數類的Vlookup屬性

If WorksheetFunction.IsNA(Application.WorksheetFunction.VLookup(ListBox1.Selected(0), Range("B4:C7"), 2, False)) = True Then
'Create row
 Range("EndlineFM").Select
   Selection.Insert Shift:=xlDown
 'Initialise Detail and montant of new row
   Range("TotalF").Offset(-1, 0) = FraisM.ListBox1.Selected(0)
Range("TotalF").Offset(-1, 1) = CSng(FraisM.Chiffremontant)

我該如何解決？ 謝謝！

Answer 1

如果找不到匹配項， Application.WorksheetFunction.VLookup將始終引發運行時錯誤-您無法使用IsNA()處理該IsNA()

您可以在沒有WorksheetFunction情況下這樣做：

Dim m    

m = Application.VLookup(ListBox1.Selected(0), Range("B4:C7"), 2, False))

If IsError(m) Then
    'Create row
     Range("EndlineFM").Insert Shift:=xlDown
     'Initialise Detail and montant of new row
     Range("TotalF").Offset(-1, 0) = FraisM.ListBox1.Selected(0)
     Range("TotalF").Offset(-1, 1) = CSng(FraisM.Chiffremontant)
     'etc

Answer 2

像這樣工作

Dim Txt As Variant
On Error Resume Next 
Txt = Application.WorksheetFunction.VLookup(FraisM.ListBox1.List(FraisM.ListBox1.ListIndex), Range("B4:C7"), 2, False)
             If Err.Number <> 0 Then
             MsgBox " Not found" ''optional, no need to do anything
             Err.Clear
             Exit Sub   ' Or may use Goto label
             End If
     On Error GoTo 0
    'Create row
     Range("EndlineFM").Select
     Selection.Insert Shift:=xlDown
    'Initialise Detail and montant of new row
     Range("TotalF").Offset(-1, 0) = Txt

我已經將FraisM用作用戶名，並假設代碼是從Module運行的。 如果您在工作表上使用Msform.ListBox ，則可以嘗試

Dim MyLB  As Object
Set MyLB = Sheet1.Shapes("List Box 1")
Txt = Application.WorksheetFunction.VLookup(MyLB.ControlFormat.List(MyLB.ControlFormat.ListIndex), Range("B4:C7"), 2, False)
