Detect running process and terminate

[yosemite]

I have a VB application that gets invoked from another
Java application. I need to check in my VB code to see if
this VB application is already running. If it is, I need to
terminate it before continuing...

Can someone give any tips to continue ?
I know I can detect the previous instance using the
App.previnstance method, but how do I kill the previous
instance ?

Thanks

' See if there is already and instance.
If App.PrevInstance Then
' Activate the previous instance
AppActivate App.Title

' Send a key (here SHIFT-key) to set the
' form from the previous instance to the
' top of the screen.
SendKeys "+", True

' Terminate the new instance
Unload Me
End If

Hello HeSaidJoe,

I tried your code, but it didn't help.

In my VB application, I get some arguments passed from
the Java application. Based on these arguments, I do
some data retrieval and post the results in a MDI window.

When the java program re-invokes the VB program, I want
to terminate the previous instance and continue processing
with the new set of arguments. This way, the MDI window
now shows data for the latest arguments.

If I use the code to terminate the current application,
the MDI window still shows the old data...

Thanks
