delphi - Embed Image to Outlook using extended mapi functions -

-

I have to preview the email before embedding images in the email and sending it to Outlook. CDO and redemption is not an option.

I have tried the following code, but the images only appear in the form of a small block

Add processTouch (full filename: string; Attachment: Outlook 2000 Attachment; cid: string); Const PR_ATTACH_CONTENT_ID = $ 3712001 E; PR_ATTACH_CONTENT_ID_W = $ 3712001F; // Unicode PR_ATTACH_MIME_TAG = $ 370E001E; PR_ATTACH_ENCODING = $ 37020102; Var IAttach: IMAPIProp; Prop: PSPropValue; Attachment: Outlook 2000. Attachment; Filename: string; Suppose: TSPProl value; Prop. 1: Tasptopagare; Start filename: = ExtractFileName (FullFileName); Prop: = zero; Attempt: Try Attachments. Add (FullFileName, olByValue, 1, FileName); IAttach: = AAttachment.MAPIOBJECT as IMAPIProp; If assigned (IAttach) try PropValue.ulPropTag: = PR_ATTACH_MIME_TAG; PropValue.Value.lpszA: = 'Image / JPEG'; HRSetAnPap (IAttach, @PropValue); PropValue.ulPropTag: = PR_ATTACH_CONTENT_ID; PropValue.Value.lpszA: = Panscher (ANIstring (CID)); HRSetAnPap (IAttach, @PropValue); Eventually, if assigned (prop) then mapfreefuffer (prop); IAttach: = Nil; End; Excluding the End; End;

The questioner has not posted his HTML text, I suspect that his CID The URLs were flawed - although I have not tested this.

If the Content-ID header is set to: 

  Content-Type: Image / JPEG Content-Displacement: Inline Content-ID: FD 383888 E 86 AD 97070 @U

Then the HTML should reference such as:

Specifically, the CID URL should have the prefix "cid:", but the content-ad head should not be. (A grid is a good option for a content-id, except that it should contain a @ symbol. You can add '@u' to the GUID.) < / P>

At the receiving end of this email message is enough to display correctly

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
