最近在項目上要做一個消息推送的組件，實習醫生站和護士站通訊的組件，醫生站開立醫囑后通知護士需要審核醫囑，會診醫囑審核之后通知會診醫生會診，我相信在其他項目上也會用到，在這里先總結一下，留著備用。廢話少說，直奔主題。

? 第一步，創建l兩個個表，如果不用表也可以用xml存。

? ? ? ?腳步如下：

? ?

1 -- Create table 2 create table COM_SYS_MSG 3 ( 4 msg_id NUMBER(10) not null, 5 msg_title VARCHAR2(50), 6 msg_content VARCHAR2(100), 7 publisher VARCHAR2(6), 8 publish_time DATE, 9 limited_area VARCHAR2(50) default 'ALL', 10 is_valid CHAR(1) default '0', 11 extend1 VARCHAR2(100), 12 extend2 VARCHAR2(100), 13 extend3 VARCHAR2(100), 14 role_area VARCHAR2(50) default 'ALL' 15 ) 16 tablespace USERS 17 pctfree 10 18 initrans 1 19 maxtrans 255 20 storage 21 ( 22 initial 192K 23 next 1M 24 minextents 1 25 maxextents unlimited 26 ); 27 -- Add comments to the table 28 comment on table COM_SYS_MSG 29 is '系統消息表，用于群發消息'; 30 -- Add comments to the columns 31 comment on column COM_SYS_MSG.msg_id 32 is '消息編碼'; 33 comment on column COM_SYS_MSG.msg_title 34 is '消息標題'; 35 comment on column COM_SYS_MSG.msg_content 36 is '消息內容'; 37 comment on column COM_SYS_MSG.publisher 38 is '消息發布者'; 39 comment on column COM_SYS_MSG.publish_time 40 is '消息發布時間'; 41 comment on column COM_SYS_MSG.limited_area 42 is '限制范圍：缺省為ALL——全部范圍'; 43 comment on column COM_SYS_MSG.is_valid 44 is '是否有效，0－無效，1－有效，缺省發布消息為0，需要確認發布才更新為1'; 45 comment on column COM_SYS_MSG.extend1 46 is '審核人'; 47 comment on column COM_SYS_MSG.extend2 48 is '接收科室'; 49 comment on column COM_SYS_MSG.role_area 50 is '角色范圍：缺省為ALL——全部范圍'; 51 -- Create/Recreate indexes 52 create index IDX_CSM_TIME on COM_SYS_MSG (PUBLISH_TIME) 53 tablespace USERS 54 pctfree 10 55 initrans 2 56 maxtrans 255 57 storage 58 ( 59 initial 64K 60 next 1M 61 minextents 1 62 maxextents unlimited 63 ); 64 -- Create/Recreate primary, unique and foreign key constraints 65 alter table COM_SYS_MSG 66 add constraint PK_COM_SYS_MSG primary key (MSG_ID) 67 using index 68 tablespace USERS 69 pctfree 10 70 initrans 2 71 maxtrans 255 72 storage 73 ( 74 initial 64K 75 next 1M 76 minextents 1 77 maxextents unlimited 78 ); 1 -- Create table 2 create table COM_IP_MSG 3 ( 4 ip_address VARCHAR2(50) not null, 5 last_view_time DATE, 6 extend1 VARCHAR2(100), 7 extend2 VARCHAR2(100), 8 extend3 VARCHAR2(100) 9 ) 10 tablespace USERS 11 pctfree 10 12 initrans 1 13 maxtrans 255 14 storage 15 ( 16 initial 64K 17 next 1M 18 minextents 1 19 maxextents unlimited 20 ); 21 -- Add comments to the table 22 comment on table COM_IP_MSG 23 is '每個IP地址的最后獲取消息記錄'; 24 -- Add comments to the columns 25 comment on column COM_IP_MSG.ip_address 26 is 'IP地址'; 27 comment on column COM_IP_MSG.last_view_time 28 is '最后獲取消息的時間'; 29 -- Create/Recreate primary, unique and foreign key constraints 30 alter table COM_IP_MSG 31 add constraint PK_CIM_IP primary key (IP_ADDRESS) 32 using index 33 tablespace USERS 34 pctfree 10 35 initrans 2 36 maxtrans 255 37 storage 38 ( 39 initial 64K 40 next 1M 41 minextents 1 42 maxextents unlimited 43 );

?第二步：

? ? 創建彈窗代碼

? ?1、準備兩張資源圖片文件

? ? 效果如下：

?2，代碼實現：

　　第三步，調用：

? ? ? ?1，在您需要顯示的窗體里面添加一個定時器，

? ? ? 代碼如下：

? ? ?

private System.Windows.Forms.Timer timer1;this.timer1 = new System.Windows.Forms.Timer(this.components);this.timer1.Tick += new System.EventHandler(this.timer1_Tick);

　　在構造函數里面添加代碼：
? ? ?

#region if (!this.DesignMode){timer1.Enabled = true;timer1.Interval = 10000;}#endregion

?

? ? 2，初始化TaskbarNotifier?

代碼如下：

#region 初始化彈窗 taskbarNotifier.SetBackgroundBitmap(MytaskbarNotifier.Properties.Resources.skin3, Color.FromArgb(255, 0, 255));taskbarNotifier.SetCloseBitmap(MytaskbarNotifier.Properties.Resources.close, Color.FromArgb(255, 0, 255), new Point(280, 57));taskbarNotifier.TitleRectangle = new Rectangle(150, 57, 125, 28);taskbarNotifier.ContentRectangle = new Rectangle(75, 92, 215, 55);taskbarNotifier.CloseClickable = true;taskbarNotifier.TitleClickable = false;taskbarNotifier.ContentClickable = true;taskbarNotifier.EnableSelectionRectangle = true;taskbarNotifier.KeepVisibleOnMousOver = true;taskbarNotifier.ReShowOnMouseOver = false;taskbarNotifier.ContentClick += new EventHandler(taskbarNotifier_ContentClick);#endregion

? ? ? ? ? ? ? ? ? ?

void taskbarNotifier_ContentClick(object sender, EventArgs e) { return;//暫時不用此功能 ｝

?

顯示代碼實習： /// <summary>/// 逐條顯示消息/// </summary>/// <param name="dsMessage"></param>private void DisplayMessage(DataRow dsMessage){try{Int32 msgID = Convert.ToInt32(dsMessage[0].ToString());string msgTitle = dsMessage[1].ToString();string msgContent = dsMessage[2].ToString();string msgPublisherCode = dsMessage[3].ToString();string msgPublisherName = dsMessage[4].ToString();DateTime msgPublishTime = Convert.ToDateTime(dsMessage[5].ToString());string msgLimitedArea = dsMessage[6].ToString();string msgIsValid = dsMessage[7].ToString();string msgExtend1 = dsMessage[8].ToString();string msgExtend2 = dsMessage[9].ToString();string msgExtend3 = dsMessage[10].ToString();string msgRoleArea = dsMessage[11].ToString();string displayTitle = msgTitle;string displayContent = msgContent + "\n\r" + msgPublisherName + "[" + msgPublisherCode + "]" + msgPublishTime;taskbarNotifier.Show(displayTitle, displayContent, 500, delayTime, 500);System.Threading.Thread.Sleep(500);this.timer1.Start();}catch{this.timer1.Stop();}}

　　實現定時器事件代碼：

decimal validTime = 1m; //系統消息有效時間int refreshTime = 5000; //刷新數據庫時間int delayTime = 5000; //提示窗口停留時間int intervalTime = 10000; //間隔顯示時間DataSet dsMessage = new DataSet(); /// <summary>/// Timer/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void timer1_Tick(object sender, EventArgs e){try{this.timer1.Stop();if (dsMessage == null || dsMessage.Tables.Count == 0 || dsMessage.Tables[0].Rows.Count == 0){ // 獲取系統消息按照權限獲取要顯示的消息table//todo sql實現 SELECT COM_SYS_MSG.MSG_ID,COM_SYS_MSG.MSG_TITLE,COM_SYS_MSG.MSG_CONTENT,COM_SYS_MSG.PUBLISHER,(SELECT COM_EMPLOYEE.EMPL_NAMEFROM COM_EMPLOYEEWHERE COM_EMPLOYEE.EMPL_CODE = COM_SYS_MSG.PUBLISHER) empl_name,COM_SYS_MSG.PUBLISH_TIME,COM_SYS_MSG.LIMITED_AREA,COM_SYS_MSG.IS_VALID,COM_SYS_MSG.EXTEND1,COM_SYS_MSG.EXTEND2,COM_SYS_MSG.EXTEND3,COM_SYS_MSG.ROLE_AREA FROM COM_SYS_MSG WHERE COM_SYS_MSG.LIMITED_AREA = 'ALL' AND (COM_SYS_MSG.ROLE_AREA = '{2}' or '{1}'='ALL') AND COM_SYS_MSG.IS_VALID = '1' and (COM_SYS_MSG.Extend2='{1}' or '{1}'='ALL') AND COM_SYS_MSG.PUBLISH_TIME>= ( SELECT COM_IP_MSG.LAST_VIEW_TIME FROM COM_IP_MSG WHERE COM_IP_MSG.IP_ADDRESS = '{0}') ORDER BY COM_SYS_MSG.PUBLISH_TIME

?
