In MainForm I’m using WaitForSingleObject, but this function freeze MainFrom, so how can I prevent reezing and wait for value?

First, design your thread with events and invoke them using Synchronize.

Create thread in MainForm and assign event handlers to it:

Thread := TMyThread.Create(True);
Thread.OnDownload := DoDownload;
Thread.OnParse := DoParse;
// Other Events
Thread.Start;

You should not WaitFor* in MainForm. Avoid Windows messages method because your app will loose platform portability, just linked to WinXX compilation.
