计算机毕业设计教师学生管理功能介绍:
3. TeacherStuderList(教师学生管理)
此模块可以通过选择教师名称,教师角色分配评定学生的课程,添加时判断信息是否重复,删除时判断信息是否已经被使用。如图:
以下是引用片段:
其相关代码如下: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click '显示当前教师列表 Dim tmpcnn As New Sql2000DB Me.DropDownList1.DataTextField = "xm" Me.DropDownList1.DataValueField = "ID" Me.DropDownList1.DataSource = tmpcnn.GetData("select * from teacher where teacher.id<>'admin'") Me.DropDownList1.DataBind() '显示当前学院的学生列表 Me.DropDownList2.DataTextField = "bjxs" Me.DropDownList2.DataValueField = "id" Me.DropDownList2.DataSource = tmpcnn.GetData("select student.id,(class.bjmc+ '-' + student.xm + '-' + student.bykt) as bjxs from student,class where student.bjid=class.bjid order by class.bjid") Me.DropDownList2.DataBind() '显示当前的角色列表 Me.DropDownList3.DataTextField = "jsmc" Me.DropDownList3.DataValueField = "jsid" Me.DropDownList3.DataSource = tmpcnn.GetData("select * from jsfs") Me.DropDownList3.DataBind() ''显示教师学生角色列表 Me.DataGrid1.DataSource = tmpcnn.GetData("SELECT *,student.xm as xsxm,teacher.xm as jsxm from Jsxs,student,teacher,jsfs where jsxs.jsid=teacher.id and jsxs.xsid=student.id and jsxs.juesid=jsfs.jsid ") Me.DataGrid1.DataBind() End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click ''核对信息是否正确 Dim tmpcnn As New Sql2000DB If tmpcnn.GetData("select * from Jsxs where xsid='" & Me.DropDownList2.SelectedValue & "' and jsid='" & Me.DropDownList1.SelectedValue & "' and juesid=" & Me.DropDownList3.SelectedValue & "").Rows.Count > 0 Then Response Exit Sub End If
