Yes, download a program called HyperCam and then there is a certain button I'm not really sure but I think it is f4 that you click for screenshot.

Thank you for your reply but HyperCam is not useful for me.
Perhaps i didn't explain my problem properly.
I'm not trying to capture my screen.
What i want to do is to take a photo with my webcam by pressing on the button on it.
Then i would like that my Java program displays the photo obtained.
Is it possible for a Java program to detect the hardware button of a webcam?

Hi There,
I am also searching for a solution to a simillar sort of problem. In our case the requirement is to; "capture the camera button click event" in JAVA.
My as of now research in this field says that it is not possible to detect a "physical device button click event" solely thru the JAVA/JMF API []Oracle Forums.
What probably we can do is; let a piece of code written in C/C++/Windows-API detect this kind of events and then we can further call upon our JAVA code with the means of JNI (Java Native Interface) from the native-language piece of code. This might be a probable solution.
I need to try this, and will definitely post in this forum after trying.
Also kindly please share accross anything useful that you come accross in this regard.
Thanks in advance,
Sumit

Hello Sumit1206,
I find the same solution: write C code and the port it in Java with JNI.
Did you find any C library doing something like this?
In my researches I find Avicap32.dll that allows to capture video from a camera but I don't think it can be useful in our case.
Most of the exemples i find was in C# and it isn't useful for me.
Did you already begin to develop the code? How are you doing?
I will go on in my researches and in the developing of the code and I'll share news.
Please do the same.
Thanks
