For some reason, FindWindow() returns NULL for an application that is currently running. I am calling this from a custom DLL (during UN-INSTALLATOIN).
the call is..
FindWindow("", "MY APP");
However, the same call works fine when i use it inside the InstallShield script during INSTALLATOIN!! What could be the difference!?
I need this call to succeed because this app is holding some DLLs & unless i close this app, UnInstall will not completely go thru.
