Closing an application from another app

Question:
How do I use one application to close another application in Windows 95? I need to overwrite a loaded DLL, so I have to close the application that loads it.

Answer:
The preferred way is to send the other application a WM_CLOSE message. The effect is the same as the user clicking on the window's close button.

Note, however, that the program might first prompt the user, asking if he or she really wants to exit or if he or she wants to save changes. Both choices give the user a chance to prevent the application from terminating. Although unlikely, the application may even simply refuse to terminate.

But this is still the best approach. Just trying to kill an application outright can result in user changes not being saved and represents very bad form.
