根据网有要求，由于子窗体字段较多，所以通过遍历子窗体所有控件，然后进行模糊查询。下载附件

 Dim strWhere As String
    Dim ctl As Control
    Dim ctlname As String
    strWhere = Trim$(Me.Text4.Text)
    For Each ctl In Me.物资库存_子窗体.Form.Controls
        If TypeOf ctl Is TextBox Then
            ctlname = ctlname & "[" & ctl.Name & "] & "

         End If
    Next
    ctlname = Left(ctlname, Len(ctlname) - 3)
      strWhere = "" & ctlname & "  like  '*" & strWhere & "*'"
      Me.物资库存_子窗体.Form.Filter = strWhere
    '应用筛选
    Me.物资库存_子窗体.Form.FilterOn = True
