I'd like to develop an application in VB.NET that contains a treeview control. The treeview is populated using an XML file that contains "contacts". So each node in the treeview represents a "contact" identified by his/her email address.
I would like my application to check if the user running the application has MSN Messenger/Windows Live Messenger active on his/her machine.
If yes, I'd like the application to check if any of the "contacts" mentioned above exists in the "contacts list" of the MSN Messanger/Windows Live Messenger'.
For each existing contact, grab the related online/offline status. Based on the status display a different icon in the application's "Contacts" treeview node.
If a MSN Messenger buddy goes off-line I'd like the application to update the icon of the related "Contact" treeview node.
Finally, if possible, when I right-click on a treeview node in my application and the related contact is "online" in MSN Messenger I'd like to enable a user to launch MSN Messenger and to chat with that online contact or do some of the other function offered by MSN Messenger.
Is this possible? If yes, pls send me all the info.
