打开Lotus Notes 时出现“打开窗口出错”

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了打开Lotus Notes 时出现“打开窗口出错”相关的知识,希望对你有一定的参考价值。

参考技术A 之前没有正常退出,还有进程没结束。
一种方法是在任务管理器里把所有n开头的进程结束
如果还不行,运行cmd,找到notes所在的路径,执行nsd -kill
参考技术B 任务管理器--进程--ntaskldr.exe--结束进程,

再打开notes就OK了~~
参考技术C 卸载后重新安装。

C#操作Lotus Notes邮件

之前的公司一直用outlook,朋友的公司在用IBM的Lotus Notes,找我说希望我帮忙做一个基于Notes的邮件提醒功能。但是无法让公司内IT来协助,也就意味着只能在User的电脑上来处理了。

Google了下,有C#的API,并查到在Notes在安装时会在本地配置文件中写入Server Name及基于当前用户的file。好,开干!

 

首先需要引入Interop.Domino.dll,这个可以去网上找(240K),也可以直接用NuGet搜Domino。

主要写了两个发邮件的Demo方法,一个仿造网上一个Java的Demo转化为C#的写法(逻辑差不多,只是具体的API名称可能不一致),缺点是样式不方便灵活定制。如下:

		/// <summary>
		/// Lotus notes email sender.
		/// </summary>
		/// <param name="mail"></param>
		/// <param name="isSupervisor"></param>
		static void SendNotesMail(NotesMail mail, bool isSupervisor = false) 
		{
			try
			{
				NotesSession nSession = new NotesSession();
				nSession.Initialize(mail.Password);
				NotesDatabase nDatabase = nSession.GetDatabase(mail.ServerName, mail.FileName);
				NotesDocument nDocument = nDatabase.CreateDocument();
			    
				/*create string variable that will be passed to function. This way we setup To field value*/
				//string[] recipients = mail.SendTo;
	
				//setup Form
				nDocument.ReplaceItemValue("Form", "Memo");
				nDocument.ReplaceItemValue("SendTo", (object)mail.SendTo); //To field
				nDocument.ReplaceItemValue("Subject", mail.Subject); //message subject
				//nDocument.ReplaceItemValue("Body", mail.Body); //set body text
				NotesRichTextItem richTextItem = nDocument.CreateRichTextItem("Body");
				richTextItem.AppendText("Hi,");
				richTextItem.AddNewLine(2);
					
				if (isSupervisor) {
					richTextItem.AppendText("The following is completion of today‘s PCN tasks: ");
				} else {
					richTextItem.AppendText("The following are the PCN tasks you should comfirm today: ");
				}
					
				richTextItem.AddNewLine(2);
					
				// Create table
				NotesRichTextParagraphStyle rtps = nSession.CreateRichTextParagraphStyle();
				rtps.LeftMargin = 0;
				rtps.FirstLineLeftMargin = 0;
				rtps.RightMargin = 1;
				List<NotesRichTextParagraphStyle> styles = new List<NotesRichTextParagraphStyle>();
      
				for (int i = 0; i < 3; i++) {
					styles.Add(rtps);
				}
				
				var rowNumber = mail.Body.Length;
				var columnNumber = mail.Body[0].ItemArray.Length;
				richTextItem.AppendTable(rowNumber, columnNumber);
				// Populate table
				NotesRichTextNavigator rtnav = richTextItem.CreateNavigator();
				rtnav.FindFirstElement(RT_ELEM.RTELEM_TYPE_TABLECELL);
				object rtnavo = (object)rtnav;
					
				for (int irow = 1; irow <= rowNumber; irow++) {
					for (int icol = 1; icol <= columnNumber; icol++) {
						richTextItem.BeginInsert(ref rtnavo);
						richTextItem.AppendText(mail.Body[irow-1][icol-1].ToString());
						richTextItem.EndInsert();
						rtnav.FindNextElement(RT_ELEM.RTELEM_TYPE_TABLECELL);
					}
				}
					
				nDocument.SaveMessageOnSend = mail.SaveMessageOnSend; //save message after it‘s sent
				object oItemValue = nDocument.GetItemValue("SendTo");
				nDocument.Send(false, ref oItemValue); //send
				
				
			}
			catch (COMException ex) {
				// Let users change their passwords if their passwords have been changed. The better way is using LDAP to check whether the password is correct or not in a windows service.
				string logFile = Path.GetFullPath(Path.Combine(logPath, string.Format("{0}.txt", DateTime.Now.ToString("yyyyMMdd"))));
				
				if (ex.Message.Contains("Notes error: Wrong Password")) {
					
					string SecurityToolPath = ConfigurationManager.AppSettings["ChangePasswordToolPath"];
					
					if (!string.IsNullOrEmpty(SecurityToolPath)&&File.Exists(SecurityToolPath)) {
						Process.Start(SecurityToolPath);
					} else {
						Log(logFile, "Password is wrong but serurity tool can not be found. Please check this config file and find the right path of security tool.");
					}
				}
				
				Log(logFile, ex.Message + Environment.NewLine + ex.StackTrace);
				
				Environment.Exit(0);
			}
			catch(Exception ex)
			{
				string logFile = Path.GetFullPath(Path.Combine(logPath, string.Format("{0}.txt", DateTime.Now.ToString("yyyyMMdd"))));
				
				Log(logFile, ex.Message+Environment.NewLine+ex.StackTrace);
				
				Environment.Exit(0);
			} 
		}

  

第二种方法可以在邮件中定义比较丰富的内容,因为可以使用HTML格式发送邮件。需要说明的是,我为了简便起见,用Word写了个邮件模板,然后转成HTML格式,再将其分成不同的部分(例如Head,Footer,body,Grid等等)保存在txt文档中,发送邮件时利用这些文件拼成一个HTML文档,如下:

	/// <summary>
	/// Send Notes email using HTML.
	/// </summary>
	/// <param name="mail"></param>
	/// <param name="isSupervisor"></param>
	static void SendNotesMailWithHTML(NotesMail mail, bool isSupervisor = false)
	{
	    /* Declare the necessary variables */
            NotesSession LNSession = new NotesSession();
            NotesDatabase LNDatabase = null;
            NotesDocument LNDocument;
            NotesMIMEEntity LNMimeRoot;
            NotesMIMEEntity LNMime;
            NotesMIMEHeader LNHeader;
            NotesStream LNStream;
            string sMessageBody = string.Empty;

            try
            {

                /* server and username would  look similar to the following */
                string server = mail.ServerName;
                string userName = mail.FileName;
                LNSession.Initialize(mail.Password);

                /* Since we will be working with MIME entities to create the mail it is important that we turn of the MIME conversion which is turned on by default. */
                LNSession.ConvertMime = false;
                LNDatabase = LNSession.GetDatabase(server, userName, false);

                /* start creating the mail document: */
                LNDocument = LNDatabase.CreateDocument();
				LNDocument.SaveMessageOnSend = mail.SaveMessageOnSend;
                LNDocument.ReplaceItemValue("Form", "Memo");
                //LNDocument.ReplaceItemValue("Principal", "System");

                /* set the recipients address */
                LNDocument.ReplaceItemValue("SendTo", (object)mail.SendTo);

                /* create the headers */
                LNMimeRoot = LNDocument.CreateMIMEEntity();
                LNMime = LNMimeRoot.CreateChildEntity();
                LNHeader = LNMimeRoot.GetNthHeader("Content-Type");
                LNHeader.SetHeaderVal("multipart/related");

                /* 
                 * Subject is defined twice (in the Subject field and MIME header value) since it is possible that the recipient(s)/client(s) can chose 
                 * NOT to display HTML and only show the text part of the mail. 
                 * Hence it is preferable set it in both Subject and MIME header. 
                 */
                LNDocument.ReplaceItemValue("Subject", mail.Subject);
                LNHeader = LNMime.CreateHeader("Subject");
                LNHeader.SetHeaderVal(mail.Subject);
                LNStream = LNSession.CreateStream();

                /*
