[RESOLVED] Try and Catch with outlook

With this code i send a email with outlook.

Code:

---


 Dim application = New Microsoft.Office.Interop.Outlook.Application
        Dim outlookEmail = CType(application.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem), MailItem)

        outlookEmail.To = "*********@gmail.com"

        outlookEmail.BodyFormat = Microsoft.Office.Interop.Outlook.OlBodyFormat.olFormatPlain

        outlookEmail.Importance = Microsoft.Office.Interop.Outlook.OlImportance.olImportanceNormal

        outlookEmail.Body = ("Test")
        outlookEmail.Subject = ("Ok")

        outlookEmail.Display(False)
        outlookEmail.Send()

---

it works great , but when there is no outlook on the pc installed the programma crash.

Try and catch is not working ?

The error is

Code:

---

'Catch' cannot catch type 'Microsoft.Office.Interop.Outlook.Exception' because it is not 'System.Exception' or a class that inherits from 'System.Exception'.

---

Who can help me ?

Depends what you mean by help. There obviously isn't any way to make this work without Outlook so the simplest way round this problem is simply to indicate to any potential users that that's the case and prevent them installing it. However there is actually no reason to involve Outlook at all in something as simple as sending an email.

Your code is assuming (You are using Early Binding) that the outlook application will be present. Why not Latebind and then check if the Outlook object exists? See this example

Code:

---

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
    Handles Button1.Click
        Dim OutApp As Object

        OutApp = CreateObject("Outlook.Application")

        If Not OutApp Is Nothing Then
            MessageBox.Show("Outlook is installed")
        Else
            MessageBox.Show("Outlook is not installed")
        End If
    End Sub

I think i can use this option , thanks

How else can an email be sent?

There are many ways. If you search google, it is full of such examples. Here are couple of them

This doesn't really make sense. You have to have Internet to send an E-Mail. Why not, then, use the same server (I assume you're using some sort of server that accepts POP3/SMTP calls) that Outlook uses? I mean, you can give it login credentials to allow you to send code. It seems silly to involve Outlook as a middle man when it's quite simple to actually bypass Outlook entirely which removes your dependency on it.
