How to: Get the SMTP Address of the Sender of a Mail Item (Office 2010)

private string GetSenderSMTPAddress(Outlook.MailItem mail)
{
string PR_SMTP_ADDRESS =
@”http://schemas.microsoft.com/mapi/proptag/0x39FE001E”;
if (mail == null)
{
throw new ArgumentNullException();
}
if (mail.SenderEmailType == “EX”)
{
Outlook.AddressEntry sender =
mail.Sender;
if (sender != null)
{
//Now we have an AddressEntry representing the Sender
if (sender.AddressEntryUserType ==
Outlook.OlAddressEntryUserType.
olExchangeUserAddressEntry
|| sender.AddressEntryUserType ==
Outlook.OlAddressEntryUserType.
olExchangeRemoteUserAddressEntry)
{
//Use the ExchangeUser object PrimarySMTPAddress
Outlook.ExchangeUser exchUser =
sender.GetExchangeUser();
if (exchUser != null)
{
return exchUser.PrimarySmtpAddress;
}
else
{
return null;
}
}
else
{
return sender.PropertyAccessor.GetProperty(
PR_SMTP_ADDRESS) as string;
}
}
else
{
return null;
}
}
else
{
return mail.SenderEmailAddress;
}
}

Return loProcesses(0)(“ParentProcessId”)

Visual Studio shows error:
Class ‘System.Management.ManagementObjectCollection’ cannot be indexed because it has no default property.

Works “straight out of the box” on Win7 32 bit with VS2010

This has answered the question I have had after previously having trouble with the compiler not recognising the “ipc” in “Imports System.Runtime.Remoting.Channels.Ipc” for some reason.
I have just spent a few hours searching for alternatives after initially being misled into believing the VB did not support the “ipc” interface directly, now I have this simple sample I can find out were I am going wrong with my original code.

Thanks again

(The alternative I was considering having to learn C#, its been many years since I have done any C++ even and I was not looking forward to having to relearn the C type syntax)

new to all this. i changed the server from a console to a form. i am able to get what is sent popping up as a message box on the server. the thing is i am trying to get it to change the text on a label instead of a message box popping up. i added a line to change the text on a label on the form to what has been received but it is just not happening! it is receiving the string that is sent as the message box is set to run after the label text change line.

i have even tried putting in a line of code that will call a sub written in the form module itself to check a checkbox…. but that wont work!

what is it that i am not doing?

this is what i am trying to accomplish….

1) change a label or button text, or even a variable or property using this tutorial and,
2) cause procedures or events to run just by sending a string that a Select Case determines by what it receives.

Thanks chaps!

thanks,
Pietro
