Checking whether a program is running or not

While performing installation, sometimes, we need to check whether the instance of a particualr program exist or not.
I got this problem while installing my plug-in. Outlook should be closed before the installation starts. So, I need to check for the existance of Outlook before installation. After so many days and lot of efforts, finally I have got a solution for this.

While Process.GetProcessesByName(“Outlook”).Length > 0

MsgBox(“Notepad is open”)
End While

MsgBox(“Outlook is still open. Please close it”)

End While

This loop will iterate until the Outlook is closed.

We can also close a program forcibly using the following code.

Dim myProcesses() As Process

Dim instance As Process

myProcesses = Process.GetProcessesByName(“Outlook”)

For Each instance In myProcesses

instance.CloseMainWindow() ‘ This will close the application that is running


Lazy add-ins

VSTO add-ins some times  irritates us by causing delay. No work around works for it and atleast a clue will not be available for us to work on that. It works fine in some systems. It loads slowly in some other systems. Some times, it even does not load in some systems.  30 second dealy, slow start-up, checking for certificate, publishing problems etc. comes under this domain.
Forums are the best places to get solutions to this kind of problems. Ofcourse, obviously almost every programmer will be going through Forums, especially VSTO programmers.
These are the links from forums for those who are sufffering from lazy add-ins (loading slowly) problem. These are the dicsussions on the delay problem. Hope this helps!
