我有一个 Outlook 插件,允许用户将电子邮件保存到数据库中。当用户保存电子邮件时,我会修改电子邮件主题,以便将其识别为已保存。
保存电子邮件可以通过两种方式进行。通过工具栏上的一个按钮,用户可以保存他们想要的任何电子邮件,还可以通过在将新电子邮件放入“已发送邮件”文件夹时出现的提示。两种方法都使用相同的表单来保存电子邮件!
好的,现在问题....
在保存电子邮件的过程中,我使用mailItem.SaveAs
将其放入文件存储的方法。成功完成后,我想更改 Outlook 中仍然存在的电子邮件主题,以说明它已成功保存。我通过更改myItem.Subject
然后使用该mailItem.Save
方法保存更改来做到这一点。
当未通过提示方法保存电子邮件时,上述方法非常有效。因此,当用户在发送电子邮件后尝试保存电子邮件时,该mailItem.Save
方法不起作用。
myItem.Save()
如果我将行放在行之前,我已将其缩小到实际工作myItem.SaveAs()
,但显然如果我这样做,我不能保证电子邮件实际上已正确保存。
那么有没有人知道mailItem.Save
该方法在调用该方法后不工作的原因mailItem.SaveAs
?
提前感谢您对可能出现的问题提出任何建议。
编辑:代码
if (_item is Outlook.MailItem) { // if the incoming item is an Outlook mail Item
// cast as a mail item
Outlook.MailItem myItem = (Outlook.MailItem)_item;
if (directoryExists(directoryTemp)) { // if the temporary directory exists
bool _profiled = true;
// copy the item as type .msg in the temporary location
myItem.SaveAs(saveTemp, Outlook.OlSaveAsType.olMSG);
// setup impersonation to copy the file to a secure location
PImpersonateUser _iU = new PImpersonateUser();
// do impersonation
try {
_iU.Impersonate("******", "******", "******");
if (File.Exists(savefile)) { // if file already exists in the location
// delete existing file
File.Delete(savefile);
}
// move the temporary file to the secure location with the proper name
File.Move(saveTemp, savefile);
string year = "";
if (ipt_year.SelectedItem != null) { // else if year has been selected
year = ipt_year.SelectedItem.ToString();
}
_profile.profileEmail(folderString(_subject_), _fileName, year);
} catch (Exception e) {
_profiled = false;
// if impersonation fails cancel the impersonation
_iU.Undo();
// show error
MessageBox.Show(e.Source + "\n\n" + e.Message + "\n\n" + e.StackTrace, "SaveAs() Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
} finally {
_iU.Undo();
}
if (_profiled) { // if the email was profiled successfully
// mark the original email as being profiled
markAsProfiled();
}
} else {
// if temporary file save fails throw error
MessageBox.Show("Temporary Directory (" + directoryTemp + ") Does Not Exist!", "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
和 markAsProfiled 函数...
private void markAsProfiled() {
if (_item is Outlook.MailItem) { // if the incoming item is an Outlook mail Item
// cast as a mail item
Outlook.MailItem myItem = (Outlook.MailItem)_item;
// make sure subject doesnt already have a profiled flag in the subject
_subject_ = _subject_.Replace("[PROFILED] - ", "");
// add a profiled flag in the subject of the email
myItem.Subject = "[PROFILED] - " + _subject_;
// add a yellow flag to the email
myItem.FlagIcon = Microsoft.Office.Interop.Outlook.OlFlagIcon.olYellowFlagIcon;
// save email with changes made
myItem.Save();
//MessageBox.Show("Mark as Profiled :: " + myItem.Subject + " :: " + myItem.Saved.ToString() + " :: ");
}
}
