instead of hitting enter, could you maybe use a workaround?

like click it with the mouse instead.

maybe use a getmouseposition, if its on the tab "take snapshot" for a specific amount of time then alert you.

just a thought. i dont think you can detect or capture keystrokes with autoit

that would be keylogging... but im not sure. that might be just for ascii characters.

that is a good question.

:EDIT oh, reading further.. you want it to react to another device button push...

you might need third party software.

or, what does the screen do when you take a picture? does it open a new window? anything? save a pic?

if you can get autoit to detect an event in the GUI then it will work

autoit will work on the windows gui and thats it. can you make the pic have a set name each time? or do you have to enter it. can you make the first pic.. "1" the second pic "2"

then you just check to see if the file exists.

it will be a little slower than detecting the actual realtime press of the camera button,

but it will work to let you know that it WAS pressed if you use this method

hope that helps

we take only one picture at time beacause we must put this picture in a database with the client name....

the question about "detect button press on a device" maybe we can get it by calling a dll or something like this... maybe when the button is press a key is modifying in the reg and modifi it again when realese. i don't know im a newbi... i will try some reg and process monitor when i press the button ...

[nobby]

Just a thought...

I know that is not what you want, but...

Instead of checking for a button pressed on the camera, you could check for the existance of the file "cam_1.jpg".

[t0ddie]

thats exactly what i already suggested nobby
