MicroERP开发技术分享:vsFlexGrid、scriptControl实现工资表自定义列与表间关系计算

开发大型的MIS系统,肯定是离不开第三方控件的,同时也要根据项目需要自己写几个。

MicroERP共用了以下几个控件:

第三方商业控件:

vsFlexGrid:大名鼎鼎的表格控件,不用多说,配合vsPrinter使用

开源的基础上修改和自己写的:

button按钮

cash会计凭证用的金额线

MDITabs MDI窗体

LeftMenu手风琴导航菜单

这里着重说一下vsFlexGrid、scriptControl的使用,以工资模块来说明表格运算及脚本编程示例。

这个控件也不是万能的,比如单元格没有change事件,很淡疼

在工资发放中,最难的就是工资表的自定义字段,某些成熟的软件用了内置上百个字段,然后由用户修改字段属性方式来完成,这里我用了“行转列”的方式,具体实现效果请参见MicroERP中的工资管理模块。

实现原理就是把预设的工资结构在填制工资表时,将表中的行转为工资表中的发放字段,某工资表数据行如下:

基本工资

岗位工资

养老保险

应发工资

应发工资=基本工资+岗位工资-养老保险

实发工资表时,显示为:

员工姓名|基本工资|岗位工资|养老保险|应发工资

员工一.......................

员工二.......................

以VB为例,实现代码如下,其它语言类似

'行转列
Public Sub SetFrame(frameID As Long)

    Dim cn As New ADODB.Connection, rs As New ADODB.Recordset, sql As String
    Dim i As Long
    btnSelectEmployee.Enabled = True
   
    sql = "SELECT tbGZItem.ItemName "
    sql = sql & "FROM (tbGZFrame INNER JOIN tbGZFrameDetail ON tbGZFrame.ID = tbGZFrameDetail.FrameID) INNER JOIN tbGZItem ON tbGZFrameDetail.ItemID = tbGZItem.ID "
    sql = sql & "where tbGZFrameDetail.FrameID=" & frameID & " order by tbGZFrameDetail.FOrder"
    On Error GoTo err
    Set cn = GetConnection
    rs.CursorLocation = adUseClient
    rs.Open sql, cn, adOpenStatic, adLockReadOnly

    
    With fg
        .Clear
        .Rows = 1
        .Cols = rs.RecordCount + 3
        For i = 3 To .Cols - 1
            .ColWidth(i) = 1300
            .ColAlignment(i) = flexAlignRightCenter
        Next i
        
        .TextMatrix(0, 1) = "EmpID"
        .TextMatrix(0, 2) = "员工姓名"

        .Cell(flexcpAlignment, 0, 1, 0, .Cols - 1) = flexAlignCenterCenter
        .ColWidth(0) = 300
        .ColHidden(1) = True

        For i = 0 To rs.RecordCount - 1
            .TextMatrix(0, i + 3) = rs.Fields("ItemName").Value
            .ColKey(i + 3) = rs.Fields("ItemName").Value
            rs.MoveNext
        Next i
    End With
    
    Exit Sub
err:
    If rs.State <> adStateClosed Then rs.Close
    Set rs = Nothing
    If cn.State <> adStateClosed Then cn.Close
    Set cn = Nothing

    MsgBox err.Description, vbCritical, "SetFrame"
End Sub


注意,.ColKey(i + 3) = rs.Fields("ItemName").Value,这句是重点。

下在是在工资表编辑时,根据字段定义,来自动计算公式列和所得税列的值

Private Sub fg_BeforeEdit(ByVal Row As Long, ByVal Col As Long, Cancel As Boolean)
    Dim formula As String '公式
    Dim funCol As String '需要计算的列
    Dim i As Integer
    Dim s As Single
    Dim q As Single
    
    If Col = 2 Then Cancel = True
    On Error GoTo err
    If Row <> 0 Then

         If GetEditMode(fg.ColKey(Col)) = "公式计算" Then
            funCol = "fg.TextMatrix(" & Row & "," & Col & ")="
            
            formula = GetFormula(mFrameID, GetItemID(fg.ColKey(Col)))
            
            '例:基本工资+补贴-保险
            '将公式替换成行列索引
            For i = 3 To fg.Cols - 1
                formula = Replace(formula, fg.ColKey(i), "fg.ValueMatrix(" & Row & ", " & fg.colIndex(fg.ColKey(i)) & ")")
            Next i
            formula = funCol & formula
    
            ScriptControl1.Reset
            ScriptControl1.AddObject "fg", fg
            ScriptControl1.ExecuteStatement formula
            
        ElseIf GetEditMode(fg.ColKey(Col)) = "所得税" Then
            txtYF.Text = Trim(GetINIstr(gAppPath & "option.ini", "system", "yffield"))
            '应发工资
            s = Val(fg.TextMatrix(Row, fg.colIndex(txtYF.Text)))
            '起征点
            q = Val(GetINIstr(gAppPath & "option.ini", "system", "gztax"))
            If s <= q Then
                fg.TextMatrix(Row, Col) = "0"
            Else
            '全月应纳税所得额
                fg.TextMatrix(Row, Col) = GetTax(s - q)
            End If
            
            
        End If
    End If
    
    Exit Sub
err:
    MsgBox err.Description, vbExclamation, "fg_BeforeEdit"
End Sub


注意:formula = Replace(formula, fg.ColKey(i), "fg.ValueMatrix(" & Row & ", " & fg.colIndex(fg.ColKey(i)) & ")"),这句是重点。
