Question

I have a java Robot program ,where it can type a word on notepad,word etc,.

But the problem is i am not getting focus of window application, when i tried to enter the cursor in its textbox manually by using ALT-TAB,

And the application is not available in the list ,while doing ALT-TAB ,
also it is not visible in Task Manager-> Application tab
but, it is available with Processes tab of Task Manager.
Is there any solution to get focus of that windows application for keyPress using Java Robot.

Also ,in some other PC’s ,i am getting Clear Focus of the application when i put the cursor manually after running the java robot program. I have installed JDK1.6 in all my PC’s. It is not working only in my PC’s.

Thanks in advance!!

I think that your best bet is to use JNA to allow you to make system calls.

Assuming a Windows program, you could use JNA to make calls to the user32.dll including dll functions such as FindWindowEx(...) and SetForegroundWindow(...) to set the window of your choice to the foreground.
