Harbour Dialect : attempt to use Outlook - get errors

Post by RolWil »

Hello my fellow XSharp enthusiasts,

I’ve made much progress with my Harbour/Clipper system migration, much of it is straight forward, but now I’m stuck again; this time on something new I’m adding, it was not in the original system: I want to be able to send an email using Outlook on any form that has an email address (I’m adding a small email icon next to any email address text box).

As always, for something new-to-me, I created a sandbox project. The form has 4 fields: recipient’s email, a subject, email body and attachment. I also added a ‘Send’ button.

The project dialect is Harbour; I’ve added the following references:
  • XSharp.Core
  • XSharp.RT
  • Microsoft.Office.Interop.Outlook
I’m using the code at this link as a starting point: Click Me

Issue: when I compile, I get the following two error messages (marked as // <--- Error 1) and // <--- Error 2) in the code sample)
1) 'Microsoft.Office.Interop.Outlook.Application' is a type, which is not valid in the given context
2) Cannot implicitly convert type 'object' to 'Microsoft.Office.Interop.Outlook.MailItem'. An explicit conversion exists (are you missing a cast?)

Any help would be much appreciated. Thank you.

Cheers
Roland

Roland,
Try this:

Code: Select all

oApp := Outlook:Application{} // curly braces to create the object
and

Code: Select all

oMsg := (Outlook.MailItem) App:CreateItem(Outlook:OlItemType:olMailItem) // cast to type

Thanks Robert for your quick response!

oApp := Outlook.Application{} did the trick! (note: I had to use '.' instead of ':')

oMsg := (Outlook.MailItem) oApp:CreateItem(Outlook:OlItemType:olMailItem) worked , just a typo 'App' needed to be oApp

Onwards and forwards :)
