How to open Outlook “New mail message” window from VB.NET

问题

I've a scenario in which user can make a selection from a grid (having uploaded files on local folder) and when user press "send", application should open Outlook "New mail message" window having selected files as attachments (which user selected from grid).

Any help will be appreciated.

If you want specifically want an outlook message and you want more options on what to send (body text, attachments, BCC, etc.):

Dim Outl As Object
Outl = CreateObject("Outlook.Application")
If Outl IsNot Nothing Then
    Dim omsg As Object
    omsg = Outl.CreateItem(0) '=Outlook.OlItemType.olMailItem'
    'set message properties here...'
    omsg.Display(True) 'will display message to user
End If

Imports System.Diagnostics

Process.Start(String.Format("mailto:{0}", address))

' set all possible parameters: '

Process.Start(String.Format("mailto:{0}?subject={1}&cc={2}&bcc={3}&body={4}", address, subject, cc, bcc, body))

' also escape spaces: '

Process.Start(String.Format("mailto:{0}?subject=\"{1}\"&cc={2}&bcc={3}&body=\"{4}\"", address, subject, cc, bcc, body))

Use next to include new line breaks:

body = body.Replace(Environment.NewLine ,"%0A")

will open default email client with new message composition dialog.

If Outlook is set as default client, it will be opened.

Anyway, never open explicitly non-default client (email, browser, etc) - that breaks clients' will and makes them hate you.

    omsg.To = "yusuf@hotmail.com"
    omsg.bcc = "yusuf@gmail.com"
    omsg.subject = "Hello"
    omsg.body = "godmorning"
    omsg.Attachments.Add("c:\HP\opcserver.txt")
    'set message properties here...'
    omsg.Display(True) 'will display message to user
