Dim rrbh As WinForm.TextBox = e.Form.Controls("RYBH")

If rrbh.text > "" Then
    filter &= " and 人员编号 = '" & rrbh.text & "'"

Dim t1 As DataTable = DataTables("收款明细表")
Dim t2 As DataTable = DataTables("付款明细表")

Dim sum1 As Double = t1.Compute("sum(数量)", filter)
Dim sum2 As Double = t1.Compute("sum(金额)", filter)
Dim sum3 As Double = t2.Compute("sum(数量)", filter)
Dim sum4 As Double = t2.Compute("sum(金额)", filter)

e.Form.Controls("SKSL").text = sum1
e.Form.Controls("fkSL").text = sum3
e.Form.Controls("SKJE").text = sum2
e.Form.Controls("FKJE").text = sum4
e.Form.Controls("SYSL").text = sum1-sum3
e.Form.Controls("SYJE").text = sum2-sum4

谢谢有点色老师的帮忙。

Dim filter As String = "1=1"

有点色老师，能解释一下这句嘛，没看懂。

后面的语句是 " and 人员编号 = '123' and 部门编号 = '456'"

那条件就多了一个and，你可以把and去掉，或者加上1=1，使条件正确

"1=1 and 人员编号 = '123' and 部门编号 = '456'"

谢谢有点色老师。

Dim rybh As WinForm.TextBox = e.Form.Controls("DJKRYBH")

Dim gysbm As WinForm.TextBox = e.Form.Controls("DJKGYSBM")

Dim spbm As WinForm.TextBox = e.Form.Controls("DJKSPBM")

Dim spjj As WinForm.TextBox = e.Form.Controls("DJKJJ")

Dim filter As String = "1=1"

If rybh.text > "" Then

filter &= " and 人员编号 = '" & rybh.text & "'"

End If

If gysbm.text > "" Then

filter &= " and 供应商编码 = '" & gysbm.text & "'"

End If

If spbm.text > "" Then

filter &= " and 商品编码 = '" & spbm.text & "'"

End If

If spjj.text > "" Then

filter &= " and 进价 = '" & spjj.text & "'"

End If

Dim t1 As DataTable = DataTables("底价款收款明细表")

Dim t2 As DataTable = DataTables("底价款业务明细表")

Dim t3 As DataTable = DataTables("底价款返款明细表")

Dim sum1 As Double = t1.Compute("sum(数量)", filter) '收款数量

Dim sum2 As Double = t1.Compute("sum(收款金额)", filter) '收款金额

Dim sum3 As Double = t2.Compute("sum(数量)", filter) '业务数量

Dim sum4 As Double = t2.Compute("sum(预付金额)", filter) '预付金额

Dim sum5 As Double = t3.Compute("sum(数量)", filter) '返款数量

Dim sum6 As Double = t3.Compute("sum(返款金额)", filter) '返款金额

e.Form.Controls("SKSL").text = sum1

e.Form.Controls("YFSL").text = sum3

e.Form.Controls("FKSL").text = sum5

e.Form.Controls("SKJE").text = sum2

e.Form.Controls("YFJE").text = sum4

e.Form.Controls("FKJE").text = sum6

e.Form.Controls("WYFSL").text = sum1-sum3

e.Form.Controls("WFKSL").text = sum1-sum5

e.Form.Controls("WFKJE").text = sum2-sum4

e.Form.Controls("WFKJE").text = sum2-sum6

有点色老师，我支行以上代码，出现如下错误，麻烦您看一下是怎么回事？

无法将类型为“Foxtable.WinForm.NumericComboBox”的对象强制转换为类型“Foxtable.WinForm.TextBox”。

Dim rybh As WinForm.TextBox = e.Form.Controls("DJKRYBH")

Dim gysbm As WinForm.TextBox = e.Form.Controls("DJKGYSBM")

Dim spbm As WinForm.TextBox = e.Form.Controls("DJKSPBM")

Dim spjj As WinForm.TextBox = e.Form.Controls("DJKJJ")

改成

Dim rybh = e.Form.Controls("DJKRYBH")

Dim gysbm = e.Form.Controls("DJKGYSBM")

Dim spbm = e.Form.Controls("DJKSPBM")

Dim spjj = e.Form.Controls("DJKJJ")

谢谢有点色老师的帮忙。
