Chào Duy Longphamduylong đã viết:Có vấn đề này thấy đơn giản mà tìm hoài không ra đáp số.
Có 2 vùng: A=Range("A1:G20"), B=Range("C3
Làm sao xác định được vùng C=A-C (là vùng A mà loại bỏ các ô trong vùng B) bằng VBA ?
Mình có cách củ chuối, như sau:Có 2 vùng: A=Range("A1:G20"), B=Range("C3
Làm sao xác định được vùng C=A-B bằng VBA ?

Code này chưa đúng đâu nha! (Nhưng ý tưởng khá hay)
Không hiểu sau em chạy code của sư phụ cứ bị lổi hoài mà không tìm được nguyên nhân
Sub Selector()
Dim i As Long, Rng As Range
On Error Resume Next
If Selection.Count = 1 Then
Selection.Select
Else
With Selection.SpecialCells(2)
Set Rng = .Areas(1)
For i = 1 To .Areas.Count
Set Rng = Range(Rng, .Areas(i))
Next i
End With
Rng.Select
End If
End SubOption Explicit
Sub Seletor()
Dim Clls As Range, Rng As Range, sRng As Range
Dim MyAdd As String
Dim rMax As Long, rMin As Long, cMax As Byte, cMin As Byte
Set Rng = Selection
With Rng
rMin = .Cells(1, 1).Row + .Rows.Count
cMin = .Cells(1, 1).Column + .Columns.Count
End With
Set sRng = Rng.Find("GPE.COM", , xlFormulas, xlWhole)
If Not sRng Is Nothing Then
MyAdd = sRng.Address
Do
With sRng
If rMin > .Row Then rMin = .Row
If rMax < .Row Then rMax = .Row
If cMin > .Column Then cMin = .Column
If cMax < .Column Then cMax = .Column
End With
Set sRng = Rng.FindNext(sRng)
Loop While Not sRng Is Nothing And sRng.Address <> MyAdd
End If
Range(Cells(rMin, cMin), Cells(rMax, cMax)).Select
End SubVậy phải sửa code của sư phụ lại thành vầy chăng:
Sub Seletor()
Dim Clls As Range, Rng As Range, sRng As Range
Dim MyAdd As String
Dim rMax As Long, rMin As Long, cMax As Byte, cMin As Byte
Set Rng = Selection
With Rng
rMin = .Cells(1, 1).Row + .Rows.Count
cMin = .Cells(1, 1).Column + .Columns.Count
End With
Set sRng = Rng.Find("*", , xlFormulas, xlWhole)
If Not sRng Is Nothing Then
MyAdd = sRng.Address
Do
With sRng
If rMin > .Row Then rMin = .Row
If rMax < .Row Then rMax = .Row
If cMin > .Column Then cMin = .Column
If cMax < .Column Then cMax = .Column
End With
Set sRng = Rng.FindNext(sRng)
Loop While Not sRng Is Nothing And sRng.Address <> MyAdd
End If
Range(Cells(rMin, cMin), Cells(rMax, cMax)).Select
End Sub
Thì thầy thêm cái Selection.Special(3) vào nữa
Sub Selector()
Dim i As Long, Rng As Range, ValRng As Range, ForRng As Range
On Error Resume Next
If Selection.Count = 1 Then
Selection.Select
Else
Set ValRng = Selection.SpecialCells(2)
Set ForRng = Selection.SpecialCells(3)
If ForRng Is Nothing Then Set ForRng = ValRng
If ValRng Is Nothing Then Set ValRng = ForRng
With Union(ValRng, ForRng)
Set Rng = .Areas(1)
For i = 1 To .Areas.Count
Set Rng = Range(Rng, .Areas(i))
Next i
End With
Rng.Select
End If
End SubDạ! Em hiểu ý của anh... nhưng vì em đọc câu hỏi của thầy Long, thấy có đoạn:
Chổ màu đỏ ấy sư phụ
Test đã đúng ý đồ. Cám ơn tất cả các bạn.
Nếu vậy thì vùng chọn này vẫn.. thừa thầy à (nếu trong vùng có cell rổng)
