Hi, I have an application that I created using Builder 4.0, now
I have to build another application that can click on buttons 
AND menus in the first application, and that can also set values
and read values in & from Edit boxes on the different panels...

What is the best way for doing it? I can change the first 
application to send the second application the handles of each
button & menu & Edit box on each panel, but will the second 
application be able to use this handles for clicking the buttons
or for reading and setting values in the edit boxes? or to open
menus and so on?

Please advice, 
Thanks!

If you can change the source code for the first application, then you could 
set it up so the second application can send custom window messages to 
control it.  That way, you don't have to worry about performing clicks at 
all.

Otherwise, the second application will have to manually locate the HWND 
handles of the desired controls and issue standard Win32 API messages to 
them directly, such as WM_COMMAND/BN_CLICKED and WM_SETTEXT.

It does not need to do that.  The second application can do that on its own.

Yes.

1. Can you please show me how to do that? if for example I have
   an EditBox that have the handle 0x73E87AD2, how do I use
   this handle to Set/Read value in that Edit box?

2. If I have a Menu that have the handle 0x24C87321, how do I 
   use this handle to perform a "Mouse" Click on this menu?

Can you Please show me how to do that? (If it's a short code...) 

Thanks!

Send WM_GETTEXT and WM_SETTEXT messages to it, like I suggested earlier.

You don't.  What you need to do instead is determine the ID of the menu item 
you are interested in executing, and then send a WM_COMMAND message to the 
menu's owner window.

Look at the FindWindow/Ex() and EnumChildWindows() functions.  Start with 
the top-level window of the app and drill down its parent-child trees until 
you find the particular child control that you want to interact with.
