项目总结：HR员工系统

介绍两个模块：员工入职，和员工返职

1、员工入职：

这一部分模块主要涉及的是ComboBox和LookUpEdit（DevExpress）绑定数据源，GV列添加超链接列，超链接文本弹出窗体传值取值，单线程从Access数据库读取信息，Datagridview添加ComboBox列并赋值等。还涉及了递归部门的问题，这个在我其他文章里有单独讲，这里就不贴了。需要的可以移步https://blog.csdn.net/qq_38374540/article/details/106259895这里查看

ComboBox和LookUpEdit（DevExpress）绑定数据源

其实我觉得这两个的主要区别就是两列和多列的问题，其他的功能暂时没涉及到，这里ComboBox只能绑定两列，显示只能显示一列，而LookupEdit可以绑定表。

            //ComboBoxstring sql;sql = "select company_FK,companyName from sys_tx_kqSystem_userLog where ISNULL(isuse,'N')='Y' and userID='" + FormM.lbluserLog.Text.Trim() + "'";DataTable dtRzgs;if (!DB.AF.execSql(sql, sqlconn, out dtRzgs)){return;}DataRow drRz = dtRzgs.NewRow();drRz["company_FK"] = "";drRz["companyName"] = "";dtRzgs.Rows.InsertAt(drRz, 0);ddlRzgs.DataSource = dtRzgs;ddlRzgs.ValueMember = "company_FK";ddlRzgs.DisplayMember = "companyName";//LookupEditsql = "select replace(Code,' ','') as Code, replace(Name,' ','') as Name,replace( Remark,' ','') as Remark from sys_tx_zply a left join sys_tx_kqSystem b on a.kqSystem = b.kqSystem where b.company_FK = '" + ddlRzgs.SelectedValue.ToString().Trim() + "'";if (!DB.AF.execSql(sql, sqlconn, out dtzply)){return;}DataRow drzply = dtzply.NewRow();drzply["Code"] = "";drzply["Name"] = "";drzply["Remark"] = "";dtzply.Rows.InsertAt(drzply, 0);ddlzply.Properties.ShowHeader = false;ddlzply.Properties.ValueMember = "Code";ddlzply.Properties.DisplayMember = "Name";ddlzply.Properties.DataSource = dtzply;ddlzply.Properties.BestFitMode = BestFitMode.BestFitResizePopup;ddlzply.EditValue = "";ddlzply.Text = "";

GV列添加超链接列

            DataGridViewLinkColumn dlink = new DataGridViewLinkColumn();dlink.Text = "删除";dlink.Name = "linkDelete";dlink.HeaderText = "删除";dlink.UseColumnTextForLinkValue = true;GV.Columns.Insert(0, dlink);

超链接文本弹出窗体传值取值

  //窗体实例化，弹出窗体，这里有个ShowDialog()和Show()的小知识点private void labgz_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e){try{//因为我是表头表身都有这个超链接，所以我在传的时候判断了一下是点击表头的还是点击表身的，0是指行项，但是表头没有行项，所以传了0GongZhong gzForm = new GongZhong(this, "head", 0);gzForm.gz(ddlRzgs.SelectedValue.ToString().Trim());gzForm.ShowDialog();return;}catch (Exception ec){MessageBox.Show("错误：" + ec.StackTrace, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);return;}}
//表身的就写在GV的点击事件里private void GV_CellContentClick(object sender, DataGridViewCellEventArgs e){try{#region 删除string buttonText = this.GV.Rows[e.RowIndex].Cells[0].Value.ToString().Trim();if (buttonText == "删除" && e.RowIndex != -1 && e.ColumnIndex == 0){if (MessageBox.Show("确定删除吗？", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK){string errMsg, sql;this.GV.Rows.RemoveAt(e.RowIndex);sesstab = (DataTable)GV.DataSource;if (GV.Rows.Count > 0){byte[] byteImage = (byte[])sesstab.Rows[0]["照片"];MemoryStream ms = new MemoryStream(byteImage);Bitmap bmpt = new Bitmap(ms);pictureBox1.Image = bmpt;}else{if (ddlzc.SelectedValue.ToString() == "0"){//MessageBox.Show(ddlRzgs.SelectedValue.ToString().Trim());MessageBox.Show("保存成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);sql = "select a.companyName 公司, b.deptName 部门, a.userID 工号, a.userName 姓名, a.Pycounts 入职次数, a.Sfz 身份证号码, a.G_sfzyxr 身份证生效日 " +" , a.G_sfzsxr 身份证失效日, a.G_fzjg 签发机关, a.BornDate 出生日期,case when sex = '0' then '男' else '女' end 性别, " +" PyDate 入职日期,case when IfDaKa = 1 then '是' else '否' end 打卡, Nation_Name 民族, HomeAddr 籍贯, " +" case when ISNULL(isZc,'')= 'E' then '转厂入职' when ISNULL(isZc,'')= 'D' then '转厂离职' else '否' end 转厂, " +" case when State = '0' then '在职' else '离职' end 状态, " +" a.G_cy 人员性质, a.G_ygxz 用工性质, c.Name 计薪方式, d.Name 工种, a.G_zply 招聘途径, a.G_ 所属厂区, a.G_dkcq 打卡厂区, SUBSTRING(a.Memo, 1, CHARINDEX(',', a.Memo) -

单线程从Access数据库读取信息

        public Thread threads;public void getBarCodeData(){try{bz = 0;string sqlAccess = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Program Files (x86)\神思二代证\ssid.mdb";OleDbConnection conn;conn = new OleDbConnection(sqlAccess);DataSet ds = new DataSet();conn.Open();string sql = "select * from citizen where isDK = 0 order by ID asc ";OleDbDataAdapter oda = new OleDbDataAdapter(sql, conn);OleDbCommandBuilder cb = new OleDbCommandBuilder(oda);oda.UpdateCommand = cb.GetUpdateCommand();oda.Fill(ds);DataTable dt;dt = ds.Tables[0];for (int i = 0;

i < dt.Rows.Count; i++){dt.Rows[i]["isDK"] = -1;}oda.Update(dt);ds.AcceptChanges();}conn.Close();int r = dt.Rows.Count;if (sesstab.Rows.Count > 0){byte[] byteImage = (byte[])sesstab.Rows[0]["照片"];MemoryStream ms = new MemoryStream(byteImage);Bitmap bmpt = new Bitmap(ms);pictureBox1.Image = bmpt;}Thread.Sleep(1000);bz = 1;return;}catch (Exception ec){MessageBox.Show(ec.Message);bz = 1;return;}}private void tm_Tick(object sender, EventArgs e){tm.Stop();if (bz == 1){if (ddlzc.SelectedValue.ToString() == "0")threads = new Thread(getBarCodeData);else if (ddlzc.SelectedValue.ToString() == "1")threads = new Thread(getBarCodeDataZC);threads.IsBackground = true;threads.Start();}tm.Start();return;}private void btnbegin_Click(object sender, EventArgs e){if (btnReadCard.Text == "开始读卡"){btnReadCard.Text = "结束读卡";GV.Columns[0].Visible = true;GV.Columns[1].Visible = true;GV.Columns["工种"].Visible = true;GV.Columns["招聘来源"].Visible = true;GV.Columns["计薪方式"].Visible = true;if (ddlzc.SelectedValue.ToString() == "0"){#region GVGV.DataSource = null;sesstab = new DataTable();sesstab.Columns.Add("介绍人", typeof(string));sesstab.Columns.Add("身份证号", typeof(string));sesstab.Columns.Add("姓名", typeof(string));sesstab.Columns.Add("性别", typeof(string));sesstab.Columns.Add("民族", typeof(string));sesstab.Columns.Add("出生日期", typeof(string));sesstab.Columns.Add("住址/籍贯", typeof(string));sesstab.Columns.Add("入职次数", typeof(string));sesstab.Columns.Add("照片", typeof(System.Byte[]));sesstab.Columns.Add("签发机关", typeof(string));sesstab.Columns.Add("有效期始", typeof(string));sesstab.Columns.Add("有效期止", typeof(string));sesstab.Columns.Add("错误信息", typeof(string));this.GV.DataSource = sesstab;this.GV.EditMode = DataGridViewEditMode.EditOnEnter;GV.Columns["身份证号"].Width = 180;GV.Columns["姓名"].Width = 75;GV.Columns["性别"].Width = 60;GV.Columns["民族"].Width = 75;GV.Columns["出生日期"].Width = 100;GV.Columns["住址/籍贯"].Width = 260;GV.Columns["入职次数"].Width = 90;GV.Columns["照片"].Width = 100;GV.Columns["签发机关"].Width = 100;GV.Columns["有效期始"].Width = 100;GV.Columns["有效期止"].Width = 100;GV.Columns["错误信息"].Width = 300;GV.Columns["身份证号"].ReadOnly = true;GV.Columns["姓名"].ReadOnly = true;GV.Columns["性别"].ReadOnly = true;GV.Columns["民族"].ReadOnly = true;GV.Columns["出生日期"].ReadOnly = true;GV.Columns["住址/籍贯"].ReadOnly = true;GV.Columns["入职次数"].ReadOnly = true;GV.Columns["照片"].ReadOnly = true;GV.Columns["签发机关"].ReadOnly = true;GV.Columns["有效期始"].ReadOnly = true;GV.Columns["有效期止"].ReadOnly = true;GV.Columns["错误信息"].ReadOnly = true;#endregionbz = 1;tm.Start();}else if (btnReadCard.Text == "结束读卡"){btnReadCard.Text = "开始读卡";tm.Stop();}}

Datagridview添加ComboBox列并赋值

赋值的在上面了，这边就贴一下添加ComboBox列的方法：

DataGridViewComboBoxColumn jxfs = new DataGridViewComboBoxColumn();sql = "select Code,Name from sys_tx_Jxfs";DataTable dtjxfs;if (!DB.AF.execSql(sql, sqlconn, out dtjxfs)){return;}jxfs.Name = "计薪方式";jxfs.DataSource = dtjxfs;jxfs.ValueMember = "Code";jxfs.DisplayMember = "Name";

2、员工返职

这块主要就一个知识点，就是一般GV添加超链接列都是添加一整列，没办法根据行项的值设置该超链接列是否显示。这里就是解决这个问题。主要思路很简单就是在数据库里查出符合条件的行项，做成一列，然后把这列变成超链接，我这个好像在别的文章里写过，这里就不贴代码了。
