你如何通过checkstate改变计算？ [英] How do you get calculations by checkstate changed?

问题描述

如果检查状态发生变化，如何完成计算？

我正在尝试通过checkstate.change事件args进行一些计算，但如果我运行它，它就不起作用。

结果是0而结果不算是0.



这是我到目前为止所做的：

How to get calculations done if a check state changes?
I am trying to do some calculations by checkstate.change event args but if i run it, it does not work.
The results is 0 whiles the results is not suppose to be 0.

This is what i have done so far:

Private Sub Vehicle_Fuel_DriverCheckBox_CheckStateChanged(sender As Object, e As EventArgs) Handles Vehicle_Fuel_DriverCheckBox.CheckStateChanged
    Try
        If Vehicle_Fuel_DriverCheckBox.CheckState = True Then
            Dim TotalCashEmoluments As Integer
            Dim VFDLmt As Integer
            Dim VHF As Integer
            Dim TotalVHF As Integer
            ' Calculating VFD

            VHF = TotalCashEmoluments * 0.125

            'Checking and deducting with limits
            If VHF = VFDLmt Then
                TotalVHF = VFDLmt
            End If

            If VHF > VFDLmt Then
                TotalVHF = VFDLmt
            End If

            If VHF < VFDLmt Then
                TotalVHF = VFDLmt + 0
            End If
        End If
    Catch ex As Exception
        MessageBox.Show(ex.StackTrace, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
    End Try
End Sub

推荐答案

当你这么做时

When you do

VHF = TotalCashEmoluments * 0.125

您的变量TotalCashEmolument根本没有初始化！

这意味着在VB.NET中它是0.这就是为什么你的结果也是0！

your variable TotalCashEmolument is not initialized at all!
That means in VB.NET that it is 0. That is why your result is 0 as well!
