我有一个包含计算字段列的数据表表单。但是,即使它具有正确的值,该字段也不会显示。有问题的字段是“numRisk”:
Sub Calculate_Risk (Form As Object)
Dim OrderPrice, IfDonePrice, TotBrSymComm, BrComm, Risk As Double
Dim Symbol As String
Dim IntRateMult, noContracts As Integer
If MinTick = 0 OR Rate = 0 Then
Exit Sub
End If
Symbol = RTrim(Form.getByName("txtSymbol").CurrentValue)
If Symbol = "" Then
Exit Sub
End If
OrderPrice = Form.getByName("fmtOrder_Price").CurrentValue
IfDonePrice = Form.getByName("fmtIf_Done_Price").CurrentValue
noContracts = Form.getByName("fmtNo_Contracts").CurrentValue
If NOT USIntRates Then
Risk = ABS(OrderPrice - IfDonePrice) / MinTick
Else
Risk = ABS(OrderPrice\1 - IfDonePrice\1) * MinTick
IntRateMult = IIf(Symbol = "FV" OR Symbol = "TU",400, 200)
Risk = ABS(Risk - IntRateMult * ABS(OrderPrice - OrderPrice\1
IfDonePrice + IfDonePrice\1))
End If
Risk = Risk * MinTickVal / Rate
TotBrSymComm = BrSymComm + BrSymCommAud
BrComm = IIf(TotBrSymComm = 0, BrCommission, BrSymCommAud + BrSymComm/Rate)
Risk = noContracts*(Risk + BrComm * 2)
Form.getByName("numRisk").Value = Risk
End Sub
该子例程从以下例程调用,该例程在加载表单时触发:
Sub FromListForm(Event as Object)
Dim Form As Object
Dim TodaysDate As New com.sun.star.util.Date
Dim CurrDate As Date
Form=Event.Source.getByName("MainForm_Grid")
Form.RowSet.first()
Do Until Form.RowSet.isAfterLast()
Get_Contract(Form)
Get_Broker_Comm(Form)
Calculate_Risk(Form)
If isEmpty(Form.getByName("OrderDate").Date) Then
CurrDate = Date()
TodaysDate.Day = Day(CurrDate)
TodaysDate.Month = Month(CurrDate)
TodaysDate.Year = Year(CurrDate)
Form.getByName("OrderDate").CurrentValue = TodaysDate
End If
Form.RowSet.next()
Loop
Form.RowSet.last()
End Sub
还有一种更有效的方法来循环遍历行吗?由于这看起来很慢,我可以看到行指针在处理每一行时在表格中向下移动。
