hàm tách số khỏi chuỗi kí tự,...!

[conghung999]

ết hàm bang VB nhé:
1 . ALT + F11 -> Insert -> Module.
2. Dán đoạn code này vào khoảng trống nhé.

Function TS(Mystr As String, Optional Dautp As String) As Double
Dim Kqng, Kqtp, Neg As Double, Kqtam As String
Dim Sotp As Double, Le As Byte
Neg = 1
Le = 0
For i = 1 To Len(Mystr)
tam = Mid(Mystr, i, 1)
Select Case tam
Case 0 To 9
Kqtam = Kqtam & tam
Case "-"
Neg = -1
Case Dautp
Kqng = Kqtam
Le = 1
Mystr = Right(Mystr, Len(Mystr) - i)
Kqtp = TS(Mystr)
Sotp = Kqtp * 10 ^ (-Len(Mystr))
End Select
Next i
Select Case Le
Case 0
TS = Kqtam
Case 1
TS = Kqng + Sotp
End Select
TS = TS * Neg
End Function

3. Chọn Files - > Save as -> save as type - > Micorossoft office excell add-ins ( *.xla) ở dưới cùng.-> lưu name = TS.
4. Tools -> add - Ins... -> TS -> ok.
5. khởi động lại excell.
chỉ cần gõ = TS(ô muốn tách số). là ok...!!!
Hàm này sẽ giúp ích rất nhiều trong làm sổ sách đấy...!!!!:thumbup::hurray::happy3:

Ðề: hàm tách số khỏi chuỗi kí tự,...!

Bạn cho hỏi trong VB tách số trong cuỗi ký tự mà bạn hướng dẫn, mình muốn lấy cả ký tự số 0, thì phải làm sao: Ví dụ: Nguyen van a thanh toan cho A so TK 0123456789. KET QUA YEU CAU la: 0123456789

Bạn giúp mình nhé.

Thanhks!

Nếu chỉ lấy hoàn toàn là số để tính toán thì sửa lại hàm trên như sau :
