1. Thanks for fixing the date bug. One question though, I thought the date Mapi properties would always return GMT, I noticed that the date returned is actaully taken the time zone into consideration. Is there a way to get the original GMT?

iret: You can use the MapiProperty.Data to get the actual filetime. Actually, we convert the filetime by using the code as following:

long filetime = MapiProperty.GetLong();

return DateTime.FromFileTime(filetime);

Hi, Please use the latest private build.

I have resolved the issue to make the MailMessage can load the embedded outlook messages exported.

[http://www.aspose.com/products/aspose.network/releases/Aspose.Network3.5.1.4.zip ](https://forum.aspose.com/products/aspose.network/releases/Aspose.Network3.5.1.4.zip)

MapiMessage msg = MapiMessage.FromFile(@“embeddedA.msg”);

MapiAttachment att = msg.Attachments[0];

if (att.ObjectData.Data != null && att.ObjectData.Data.Length > 0)
{
using (System.IO.FileStream fs = System.IO.File.OpenWrite(@“embeddedObject.msg”))
{
fs.Write(att.ObjectData.Data, 0, att.ObjectData.Data.Length);
}
}

//load the embedded message use MailMessage, and save it to Mht

MailMessage emlmessage = MailMessage.Load(“embeddedObject.msg”, MessageFormat.Msg);
emlmessage.Save(“embeddedtest.mht”, MessageFormat.Mht);

Thank you for all the new features and fixes, I will try all of them shortly.

Here is an example (see attached) for the scenario two I talked about. How I generated this file is by using outlook to create a message, and choose Insert-> object->select tab "create from file" --> select file and select "Display as Icon" checkbox.

The example msg has a pdf doc embedded in it, I extracted the pdf (attached as well, named 0.pdf), but Adobe can't open it. It looks to me the extracted file has some type of wrapper to it.

As to the mht rendering of this scenario two, we hope the icon can be rendered. Basically we would like anything user can see in Outlook be rendered in mht.

iret · June 12, 2007, 11:03am

Yes, It looks still some header on it. I am looking into this issue, I will get back to you soon.

For the mht rendering, we need to improve the Rtf->Html engine, which will handle most of the case you mentioned including your previous crash.

Thanks

becky_bai · June 12, 2007, 12:49pm

I tried the mht part, it still returns an almost empty file. Could it be license issue? If one were to use evaluation license, is the mht rendered in full?

Thanks!

iret · June 12, 2007, 9:14pm

No, the evaluation copy can do the job, but inject some mark in the subject. Please double check:

1. Please make sure you have used the latest version of dll, v3.5.1.4.

2. Use the HtmlEmail.msg that you sent me before, I can export it properly use the v3.5.1.4

The attached mht is my output for HtmlEmail.msg, check it out to see if you can get the same.

Thanks,

Per your previous post for embedded Pdf document,

We have decoded the header being added to the pdf file. Now we can automatically detect the document type, if it is adobe pdf document, we do some extra document header removing. I will release a private built binary to you shortly. My outlook (office 2007) cannot make an embedded document showing icon. If you can provide me other document types, like ppt or CAD, it could be greatly appreciated. I tested about bmp, avi, they both embedded as a non Ole way.

But I think microsoft office files will work quit the same way. We just need to hack other Ole embedded document case by case.

Per your need on rendering the icon of the mail body in mht document, it seems we cannot provide any solutions. After the hacking of the icon disply in outlook messsage, we found microsoft uses local path to identify the document icon itself. No icon pic is embedded into the Outlook message. They all depend on the local machine settings. Therefore, it is a little difficult to render the icon by ourself.

Some data from the msg file shows the icon depends on local system.

iret · June 13, 2007, 8:08am

For the embedded Outlook message, we are still working on the header hacking and analysis. We cannot get the key by now.

However, you can use MapiMessage to load the extracted embedded outlook message.

Thanks

becky_bai · June 13, 2007, 12:02pm

Thanks you for your quick responses!

Attached please find other file types I embedded in msg. They are .ppt (is .pps and .pot treated the same, I included them as well), .txt, .msg.

If rendering the icons exactly as they show in the message is difficult, is it possible to replace it with some generic icon? So that at least the we can tell where in the message a ole object is inserted.

iret · June 13, 2007, 12:15pm

1. Yes, It is possible. Maybe we can insert some text or other common icon to identify the embedded Ole object in the mht.

Is it reasonable?

2. All of the embedded object is stored in storage document format. How do you think if we expose more document details, therefore you guys can be able to create custom document extracting? For example, a StorageStream class, which can access the document by low level supports.

Thanks,

nparis · June 13, 2007, 12:32pm

I think inserting some text is definitely reasonable. Maybe something like <OLE:filename> which denotes an OLE file was embedded at that spot. Does that work?

2. Can you support the MS Office( Excel, Word, PPT, Visio) and PDF file types by default and then also supply the StorageStream for other file types? If so I think that is actually a good plan. I am guessing that if the file type is “Package” we would then use the StorageStream to then do any custom extraction, is that correct?

Thanks

iret · June 13, 2007, 9:27pm

1. Yes, we will add this feature as soon as possible.

2. For MS office, PDF file types, we will provide built-in support -- their document content will be extracted properly. Besides, we will also expose a StorageStream for the OLE file, therefore you can do custom extraction. We will also try to guess the type of document like MSOffice, PDF or Unknow if possible.

Thanks

iret · June 13, 2007, 9:31pm

Hi, the EmbeddedOleFiles.rar that you sent me is a MSWord document.

Could you provide me a MS outlook message document?

Thanks a lot.

becky_bai · June 13, 2007, 9:37pm

Oops, here you go. Thanks!

becky_bai · June 13, 2007, 9:40pm

Is there a way to get the file name or file extension of the embedded MS office types or Pdf, so that we will know what extension to give when saving the files?

Thanks!

becky_bai · June 15, 2007, 11:30am

I still can't make the mht generated properly. I checked the version, it is 3.5.1.4. Attached please find the dll, the mht generated and the msg. The pattern of the mht content is that it is almost empty, only the date field is populated and its valued is the time when the mht is generated.

Here is my code:

MailMessage message = new MailMessage();

MailMessage.Load(inputPath, MessageFormat.Msg);

string outputFilePath = EmailParserUtil.GetOutputMhtFilePath(inputPath, outputFolder);

if (Directory.Exists(outputFolder) == false)

{

Directory.CreateDirectory(outputFolder);

}

message.Save(outputFilePath, MessageFormat.Mht);

iret · June 15, 2007, 8:51pm

'Check it out. The MailMessage.Load returns a new instance of MailMessage class. Please use it to get the mailmessage instance, instead of creating it using contructor.

MailMessage message = MailMessage.Load(inputPath, MessageFormat.Msg);

string outputFilePath = EmailParserUtil.GetOutputMhtFilePath(inputPath, outputFolder);

if (Directory.Exists(outputFolder) == false)

{

Directory.CreateDirectory(outputFolder);

}

message.Save(outputFilePath, MessageFormat.Mht);

becky_bai · June 18, 2007, 9:12am

Thanks, I was able to get the same result as yours.

I tried generating mht for messages that has attachments to it, I noticed that the attachments are not rendered in the mht. Here are two scenarios I tried:

1. Message in Html format: the attachments (the icon and the file name) are expected to get rendered in the header.

2. Message in Rtf format: the attachments (icon and file name) are expected to get rendered inline within the message.

I have attached an example for each cases and the current mht output I generated.

Thank you!

iret · June 18, 2007, 11:16am

Hello,

We are still working on the Rtf engine. It takes more time as we expected. We have to write a Rtf parser and html writer.

Here is the latest built,

Add OleDocumentFormat for indicating the file format of the Ole document
Add supporting for Package type Ole document
Beta Rtf render engine
Embedded image in the body is still not supported in this version. However, I fixed the crash in it.

For your scenarios, we will discuss and get back to you soon,

Thanks,
