I have found a executable that I can use to hide all the servers that are open. I am sure that it can be done ... maybe not with FindWindow , but I`m sure 100% that somehow it can be done ... anyone know how ?
1.locate windows by process ID not by title name
2. easiest - start your servers by your application with create process. Then you have control over all servers )showing, hiding, closing, sending messages, etc)
