Question

您可能会尝试声明这是重复的，但就我搜索堆栈溢出和一些搜索引擎而言，我已经意识到它们都没有解决我的问题，所以这是我的代码：

这是我的保存按钮

If chkPic.CheckState = CheckState.Checked Then
            myr.Close()
            mycom.CommandText = "Insert into tbl_employee(Picture) values (Ok) where LastName = '" & txtLastName.Text & "' AND FirstName = '" & txtFirstName.Text & "' AND MiddleName = '" & txtMiddleName.Text & "' "
            myr = mycom.ExecuteReader
        End If

这是我的更新按钮

If chkPic.Checked Then
            myr.Close()
            mycom.CommandText = "Update tbl_employee set Picture = '& Ok &' where LastName='" & txtLastName.Text & "' and FirstName='" & txtFirstName.Text & "' and MiddleName='" & txtMiddleName.Text & "' "
            myr = mycom.ExecuteReader
            myr.Close()
        Else
            myr.Close()
            mycom.CommandText = "Update tbl_employee set Picture = '' where LastName='" & txtLastName.Text & "' and FirstName='" & txtFirstName.Text & "' and MiddleName='" & txtMiddleName.Text & "' "
            myr = mycom.ExecuteReader
            myr.Close()
        End If

我还想考虑如何在我丢失的焦点事件中读取其数据，我编码为：

        If myr(75) = "Ok" Then
        chkPic.CheckState = CheckState.Checked
    Else
        chkPic.CheckState = CheckState.Unchecked
    End If

请任何人帮忙..谢谢
