[Dev-C++] Detection of windows. Java programmer needs C help.

[<jrg...@ya...>]

Hello everybody.

Here's the background story. I love to play scrabble online (for you =
Swedes
who reads this, visit www.betapet.com if you want to play). I have =
written a
small program that helps me to keep track of which the remaining letters =
are
(click on the link for a screenshot:
http://www.holdemprogs.com/Tracker.jpg). As it is now I manually either =
have
to type in the letters or use my mouse by clicking on the letters when I
want to reduce the number of unknowns. During the game I more or less =
always
at some point forget to update my little program forcing me to reset and
reenter all of the known letters in the input field. I thought if I =
could
automate the process of updating it would be great. As far as I know =
there
are two ways of finding out which the new letters being put on the board
are:
1) Using some sort of sniffer (I think that's what it called) that =
listens
to the communication between the browser and the game server=20
or
2) Image processing by comparing screenshots.

I personally have no idea how to do the first, so I'm going to go with =
the
second option, using some sort of neural network.

I could of course take a screenshot of my whole screen and do the =
processing
from there, but I feel that that will cause unessecary load to the CPU. =
This
bring me to the real reason of this letter. I would like to identify the
game window by getting the text in the title bar and when a positive
identification is made find out the size and position of the window. =
This is
not something I can do directly in Java but I think it could be done by
using JNI (Java Native Interface). Unfortunatelly my limited knowledge =
of C
and C++ doesn't include Windows API programming so I'm totally stuck.

At Planet Source Code I found a piece of code, see
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=3D657=
3&lng
WId=3D3, that alters the window text of the active window by adding the
current memory status. From this code I could figure out that the =
function
GetWindowText(=85) was used for getting the text in the title bar, but I =
din't
get much of the rest.

I would really appreciate if any of you guys could help me out by =
writing
source code for the below methods.
string[] getWindowTextForAllWindows()
int getX(string windowText)
int getY(string windowText)
int getWidth(string windowText)
int getHeight(string windowText)
bool isWindowActive(string windowText) // If the window isn't in front
there's no use in taking a screenshot

A thousand thanks in advance and best regards,
J=F6rgen Persson
