Answer 1

如果您的代码没有空间，那么下面的代码将有所帮助。

子测试（）

Data = "A850085_MDC-WP-01003_SRI Phase 2 - Programme Manager - Dionysios Psachoulias"

startpos = InStr(Data, "WP")
If startpos = 0 Then startpos = InStr(Data, "MD")

fisrtNumPos = 0
LastNumPos = 0
For i = startpos To Len(Data)

    If fisrtNumPos = 0 And LastNumPos = 0 Then
        If IsNumeric(Mid(Data, i, 1)) Then
            fisrtNumPos = i
        End If
    Else
        If Not IsNumeric(Mid(Data, i, 1)) Then
            LastNumPos = i
            Exit For
        End If
    End If
Next i

Endpos = LastNumPos - startpos

Debug.Print Mid(Data, startpos, Endpos)

结束子

现在应该可以了。但如果文本包含“MD”后跟“WP”，那么它将仅从 WP 获取代码。

例如：数据=“A850085_WPC-MD-01003_SRI 第 2 阶段 - 项目经理 - Dionysios Psachoulias”

那么结果将是 result="WPC-MD-01003"

Answer 2

尝试一些类似的东西： -

Dim cell
Dim tmp as string

For each cell in activesheet.columns(1).usedrange.cells
    If InStr(1, cell.Value, "_MDC_", vbTextCompare) > 0 Then
        tmp = Right(cell.Value, Len(cell.Value) - InStr(1, cell.Value, "_MDC_", vbTextCompare))
        tmp = Left(tmp, InStr(1, tmp, " ", vbTextCompare) - 1)
        cell.offset(0,2).value = tmp
    End If
next cell

公共函数 GetCode(data As String) As String

startpos = InStr(data, "WP")
If startpos = 0 Then startpos = InStr(data, "MD")

fisrtNumPos = 0
For i = startpos To Len(data)

    If fisrtNumPos = 0 And LastNumPos = 0 Then
        If IsNumeric(Mid(data, i, 1)) Then
            fisrtNumPos = i
        End If
    Else
        If Not IsNumeric(Mid(data, i, 1)) Then
            LastNumPos = i
            Exit For
        End If
    End If
Next i

Endpos = LastNumPos - startpos

GetCode = Mid(data, startpos, Endpos)

结束功能

在任何模块中添加此代码并尝试。
