Hi everyone:

Thank you for your answer Gambit...

You are right HWND does not change. Therefore, for some reason the PID I get
from the "CreateProcess" is not directly associated with the application's
Main Window; thats why sometimes I get a DDE server HWND instead of the
app's main window.

So, what to do?, I just need to post messages the main windows of
applications spawned with "CreateProcess" any ideas?

I pass the node as a parameter because when the process finishes I still
need to know what node in the TTreeView refers to that process in order to
update the treeview labels.

I noticed that calling  "LookForWindowHandle" right after the process is
created does not guarantee to retrieve the handle (maybe because of the time
that takes for an application to load). This is why I re-retrieve the HWND.
Although, you are right! once gotten there's no need to re-retrieve it.

Now, if a program can have multiple windows (like word documents or IE) how
does windows distinguishes among all them?, isn't that why the HWND is there
in the first place?


As an additional comment, I have found that FindExecutable also retrieves
dll modules in windows XP (like for .bmp files) and (as far as I know)
CreateProcess cannot use dlls.

Any help will be greatly appreciated...
