I am using late binding to connect to MS Outlook and to open and extract info from outlook emails using the MailItemobject.
I am trying to save attachments to file. This is fairly straightforward in most instances using the Attachment object and its SaveAsFile method.
However, it does not work where the Attachment Type is olOLE. I believe this only relates to documents embedded in emails created in RTF format (hopefully few and far between nowadays).
Via the Attachment object it is possible to access MAPI properties not exposed by the object model using its PropertyAccessor.
The relevant MAPI property for OLE objects is PR_ATTACH_DATA_OBJ, which can be accessed using the PropertyInspector as in the following example:
Function SaveOLEAttachmentToFile(Attachment:Variant; fn:String): boolean;
var
OPA, PropName : Variant;
begin
Result := false;
OPA := Attachment.PropertyAccessor;
PropName := 'http://schemas.microsoft.com/mapi/proptag/0x3701000D '; //PR_ATTACH_DATA_OBJ
?????? := OPA.GetProperty(PropName);
end;
I am stuck at this point as I can't know work out what Delphi type to save the data to and I am not even sure this is possible having read the MS documentation (Click here). PR_ATTACH_DATA_OBJ returns a PT_OBJECT. I am hoping that this object contains the raw data which (if I could work out how to access it in Delphi) can be simply saved to a file. However, the documentation suggests it may not be that simple and it's possible I may have to work with Extended MAPI. I have spent a few hours researching the latter with no concrete result other than a headache. I appreciate I could use Redemption, but I don't want to use a third party tool for something which is fairly minor in the round.
If anyone can advise as to a data type to hold the PT_OBJECT from which it can be simply saved to file that would be my route one.
Failing that, if I need to dig deeper into MAPI, I would be grateful if anyone could clarify/amplify my research so far. I have the following steps:
Initialize MAPI.
Get an IMAPIPROP interface. I think I should be getting the interface from my Attachment object and the following seems to work (ie compiles and executes without problems): MAPIPROP := IUnknown(Attachment.MAPIObject) as IMAPIPROP. Failing that, I would have to cast the parent MailItem to IMAPIPROP interface and work my way down to the attachment via GetAttachmentTable.
Load the attachment data into an IStream: if Succeeded(MAPIPROP.OpenProperty(PR_ATTACH_DATA_OBJ, IStream, STGM_READ, 0, IUnknown(SourceStream)) then
Extract the data from the IStream and save to file
I have failed to get as far as point 3 as something would seem to be wrong with my initial casting to IMAPIPROP albeit it does not cause any violations. I have tried reading a single property from the MailItem cast to IMAPIPROP using the following code:
if (Succeeded(HrGetOneProp(MAPIPROP, PR_SUBJECT, Prop))) then
And I get an access violation. Likewise if I cast the Attachment object and query an attachment property I also get a violation. I don't think the problem lies with the call to HrGetOneProp, I think it has to be the casting to IMAPIPROP.
Any pointers re the above would be greatly appreciated.
Not quite an answer to my question, but I have thought of an alternative solution. What I am ultimately trying to do is convert a msg email as a pdf. To do that I need to extract the body and then somehow insert the embedded images. With an html email this seemed pretty straightforward ((1) extract all the attachments to a folder, (2) parse the html body for references to SRC IMG and update the location of the image to reference the saved files and (3) save the edited html body to file and open it in Word and save as PDF).
RTF emails cannot be handled in this way. However, for my specific problem there is a much easier way to achieve what I need for all email types using Outtlook and Word.
Use the MailItem.SaveAs function and save the email in either html format or mthml. The former format will save all embedded images to a sub-folder (in png and jpg formats) should you need them for any other reason. once you have your html file, open it with Word and save to PDF.
If Office is not a solution then you need to figure Istorage or use one of the Extended MAPI solutions such as Redemption.
For Delphi users there are also the following commercial offerings that I have come across in my recent travels:
IMIBO
Scalabium
Rapware
I did come across one more solution which I can't find at the moment! Will post an update if I do.
PropertyAccessor (and the Outlook Object Model in general) does not handle PT_OBJECT type properties.
What you need to do is open the PR_ATTACH_DATA_OBJ property as IStorage, and then extract the data from there (it depends on the actual type of the attachment). You can see the data in the streams in OutlookSpy (I am its author) - select the message, click IMessage button on the OutlookSpy rubbon, go to the GetAttachmentTable tab, double click on the attachment to open it, select the PR_ATTACH_DATA_OBJ property, right click, select IMAPIProp::OpenProperty, then IStorage.
If using Redemption (I am also its author) is an option, its version of RDOAttachment.SaveAsFile handles OLE attachment for the most popular formats (Word, Excel, bitmap, Power Point, Adobe PDF, etc.) - create an instance of the RDOSession object (using either CrealeOleObject or RedemptionLoader) and use RDOSession.GetRDOObjectFromOutlookObject method (pass either Attachment or MailItem object) to get back RDOMail or RDOAttachment object respectively.
I am working on asp.net mvc. I am trying to display the rich text formatted content like,
{\rtf1\ansi\ansicpg1252\uc1\htmautsp\deff2{\fonttbl{\f0\

}
}
in the view. Actually this data could come from database table and i need to display it in the editor type control. so is there any open source controls that are able to display rich text format.
Well, I just got done writing a RTF to HTML converter that maintains all embedded media, and creates a MIME multipart message out of it. This is close to what you want to do. Essentially if you aren't interested in writing your own converter, you can look at this CodeProject and use his: http://www.codeproject.com/Articles/27431/Writing-Your-Own-RTF-Converter
There is also descriptions as to how to reach his solution.
On my project we just started ripping apart the RTF document and parsing its contents. Open source and 3rd-Party Libraries weren't an option for me.
I have a Richedit that allows my users to format and view error messages that display within my application.
I now need to be able to export the text only (no formatting) out to another database that their trouble-ticket system uses.
I have tried all the combinations of PlainText I can think of and I always still get the rtf formatting.
How can I get the text only?
To obtain the unformatted text, simply use RichEdit1.Text.
Answering the direct question that you asked, the Text property is precisely what you are looking for. For some reason it doesn't show up in the TRichEdit documentation, but it is inherited from TCustomEdit.
It sounds to me (following comments to Andreas' answer) as though what you really need to do it as follows:
Pull the RTF from the DB into a memory stream or perhaps a blob stream.
Call RichEdit.LoadFromStream passing that stream, making sure PlainText is False.
Then read RichEdit.Text to get the unformatted text.
At the moment you are simply putting the RTF into the control as plain text. You need to put it into the control as rich text, and for that you need LoadFromStream.
i use this way to get unformatted text
procedure TMainForm.O1Click(Sender: TObject);
begin
if sOpenDialog1.Execute then
sRichEdit1.Lines.LoadFromFile(sOpenDialog1.FileName);
sMemo1.Text := sRichEdit1.Text;
sRichEdit1.Clear;
sRichEdit1.Text := sMemo1.Text;
for save file you have to choices
save as .txt the text still in memo but all change you made will be in richedit only so you have to move text to memo after done all your changes then save it from memo
save as .rtf just save it from richedit
I hope thats help you
I am currently exporting to Excel using the old HTML trick, where I set the MIME type to application/ms-excel. This gives the added benefit of nicely formatted tables, however the negative of the excel document not being native Excel format.
I could export it as CSV, but then this would not be formatted.
I have read brief snippets that you can export it as XML to create the Excel document, but cannot find too much information on this. Does anybody know of any tutorials and/or benefits of this? Can it be formatted tables using this method?
Thanks.
Easiest way, you could parse your table and export it in Excel XML format, see this for example: http://blogs.msdn.com/b/brian_jones/archive/2005/06/27/433152.aspx
It allows you to format the table as you whish (borders, fonts,colors, I think even formulas), and Excel will recognize it as native excel format. As a plus, you can use other programs that can import Excel XML (ie.Open office, Excel viewer,etc) and you do not need to have Office components installed on the server.
Check out ExcelXmlWriter.
We've been using it for some time and it works well. There are some downsides to the xml format however. Since it's unlikely your end users will have the .xml extension associated with Excel, you end up having to download files as .xls with an Excel mime type. When a user opens a file downloaded in this way they get a warning that the file is not in xls format. If they click through it, the file opens normally.
The only alternative is a paid library to generate native Excel files. That's certainly the best solution but last time we looked there were no good, free libraries (may have changed)
Bill Sternberger has blogged a very simple solution here:
export to excel or csv from asp.net mvc
Just today I had to write a routine that exported data to excel in an MVC application. Here's the details so someone may benefit in the future, first the user had to select some date ranges and areas for the report. On the post back, this method was in place, with TheModelTypeList containing the data from LINQ/Entity Framework/SQL Query returning strong types:
if (ExportToExcel) {
var stream = new MemoryStream();
var serializer = new XmlSerializer(typeof(List<SomeModelType>));
serializer.Serialize(stream, TheModelTypeList);
stream.Position = 0;
FSR = new FileStreamResult(stream, "application/vnd.ms-excel");
}
The only catch on this one was the file type was not known when opening so the system prompted for the application to open it... this is a result of the content being XML.... I'm still working on that.
I am using Spreadsheet Light, an Open-Source library that provides ridiculously easy creation, manipulation and saving of an Excel sheet from C#. You can have an MVC / WebAPI Controller do the work of creating the file and either
Return a URL link to the saved Excel file to the page and invoke Excel to open it with an ActiveX object
Return a Data Content Stream to the page
Return a URL link to the calling page to force an Open / Save As dialog

I need to parse large text (about 1000 pages of word or pdf document)and place some of the text inside this document into database fields
I found that the only thing I can distinguish the text I want to extract is the format , it is always "Helvetica-Condensed" size 12
can I do that ? I know how to use the string functions but what I should use to test the format ?
as I said the text is stored inside word document or PDF
if there is third party component can do no problem please refer it to me
Thanks
There is QuickPDF. The price is $249,00.
The other option is to code it yourself. The file specification is available online, and if your only trying to rip the text out of the document this should guide you most of the way.
The only thing to be careful of are documents which are built entirely from images. In that scenario (no matter what you use to read the file) you will also need an OCR type of application. To see if this is the case or not, open a sample of the type of file you are wanting to "extract" text from, select the text to copy then try to paste into notepad.
