Inserting HTML in Outlook
Attempting to insert HTML in the body

We have an Add-in that inserts HTML into the body of an Outlook email message.


...
mailItem.HTMLBody = //Some HTML  <DocType .><html> .... </html>


Everything renders properly.

I was just handed a requirement that the HTML should be inserted where ever the cursor happens to be located in the message body.

We're well aware about the unusual nature of this request. I'd be curious to see how this would be done, if possible.

My first thought was to use the "WordEditor" object of the Inspector and cast it to a "Document" object. This didn't work because regardless of which "InsertXXX" function (e.g. InsertAfter), the HTML was rendered as plain text (You saw the literal HTML; tags and all)

Is there are REASONABLE way of accomplishing this?

Hello German,

Put the HTML in the Clipboard and then try to get Inspector.WordEditor, cast it to Word.Document, get Document.Windows(1), Window.Selection, Selection.Range, and finally, use Range.PasteSpecial(Type.Missing, Type.Missing, Type.Missing, Word.WdPasteDataType.wdPasteHTML).

Thank for the response.

I got the following error:

System.Runtime.InteropServices.COMException (0x800A14DE): The specified data type is unavailable.




Microsoft.Office.Interop.Word.Document doc = inspector.WordEditor as Microsoft.Office.Interop.Word.Document;
Microsoft.Office.Interop.Word.Windows wins = doc.Windows;

Microsoft.Office.Interop.Word.Window win = doc.Windows[1];

System.Windows.Forms.Clipboard.SetText(rm.GetString("HTML_FROM_EMBEDED_STRING_RESOURCE"));

win.Selection.Range.PasteSpecial(Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Word.WdPasteDataType.wdPasteHTML);


I also tried Selection.Range.PasteSpecial ... but with no luck.

Hello German,

Put the HTML to be pasted to the Clipboard, switch to the email inspector, on the Message tab select Paste | Paste Special, and check that the HTML Format item is available in the As: listbox. If it isn't available, you won't be able to paste that text as HTML.

Nice piece of trouble shooting. The HTML paste option was not available when I followed your example. Now, I know.
Thanks.

I'm thinking of trying something like this

Message Body: Some Random Text

HTML Text: <html><body><table>...</table></body></html>

Now, if I want to insert the html between the words "Random" and "Text" I could try something like this

<html><body>Some Random <table>...</table>Text</body></html>


I'd merge the text within the <body> section of the HTML.

I'm not sure how painful this will be, but I'll give it a shot.

Thanks again for your help.

Hello German,

I suggest that you invest in preparing a proper HTML which Word might insert.

Hello Andrei,

I found a solution on another site. The following will work


Outlook.MailItem mailItem = Globals.ThisAddIn.Application.ActiveInspector().CurrentItem;
Word.Document wdDoc = mailItem.GetInspector.WordEditor;
wdDoc.Application.Selection.InsertFile(FileName: @"D:.txt", Attachment: false);
