Hi, I have two problems. I have this program:
But I dont know how can I do:

1 that I finish this program and save text to .txt by press of ENTER

2 that window, in which will be field to write text, will be illustrated in main window, but I want to write this text in moment when program will be started, so I must use WS_CLIPSIBLINGS

Thanks for advices.
