Check if Application is running

Hello,

I have a VB application that launches another application from one of the menu items.

When unloading the form I would like to find out if the external application is running or not and then kill the external application only if it is running.

I have been successful in killing the application, I want to know how can I check if the external application is running or not.

Thanks
Harini

Enumerate windows and see if the application is running. You can find window by its caption or fraction of the caption.

Hello Iouri,

The code that u have sent works on the basis of WindowText. But the external application runs in the form of an icon in the task bar.

Please instruct me accordingly.
Thank u for the prompt reply

Thanks

It is still a window. When you run your app, hit Ctrl-Alt_Del and see in the Task manager the name of its window. Then perform search of this window

I tried it and it works great. How would you implement the same functionality for checking a process a remote server?
