Visuals in Mail.dll

Question

First, I would like to say that I use your product for more than 6 months now for my CRM web app and I am happy with it . I have correctly received more than 100.000 e-mails with no errors.

Here is my issue,
When a user opens an e-mail, I show the attached files using the nonvisuals collection. In very most cases it works, but I have a problem with some iphone e-mail. The nonvisual collections is empty although there is 2 attached files.

Do I do wrong when I look for the attached files in the nonvisuals collection?
Should I look into some other collections?

Thank you for your help.

2 other little things:
There may be a mistake in the documentation. Indeed you say that nonvisuals collection contains visual elements and that visuals collection contains non visual elements (see screenshot below).

When I debug, I don’t see the names of the properties of your objects. I see squares instead, then it is quite hard to debug (see my screenshot below). I use Visual Studio Enterprise 2017. Do you know what I could do?

Do I do wrong when I look for the attached files in the nonvisuals collection?

NonVisuals contains all attachments that have content-disposition set
to "attachment" (real attachments).

Now, this happens a lot with apple/iphone emails, those devices tend to send emails like this:

1. "Hello this is my photo:", text, (inline)

2. image, (inline)

3. "Hope you like it", text, (inline)

Most clients would use HTML and send this differently:

1. "Hello this is my photo <img href="cid:123" /> hope you like it.", html, (inline)

2. image, (inline), (content-id:123)

Your only option is to traverse all visual elements and display them one by one beneath IMail.Text in such situation.

You are right! Sorry for that, we'll fix that in the next release.

When I debug, I don’t see the names of the properties of your objects.

Those are private properties and this is because of obfuscation, can't change that really.
