Getting information of another window in java...

I was wondering if Java has the ability to get information from another window. I was using a program called AutoIt v3 Active Window Info, and it gets different information from a window such as the buttons and text fields in the window. I've included a couple of pictures to demonstrate it doing this.

Anyone have any ideas on how to do this in Java? Thanks

I don't believe its possible to do this unless you use JNI.

So I would have to use JNI and c++ or something?

You could certainly do it using JNI and C++ to the Windows SDK.

This is the first time I've tried messing with JNI, so from what I read I tried through together some code. I first tested out the Hello world idea and that worked fine for me. Then II took my code that worked in C++ and tried to use it with JNI, and got some errors. Here's my code, followed by the errors...

Code:

---

POINT pt;
pt.x=200;
pt.y=570;
int nMaxCount = 10;
char buff[20];

HWND hWndParent;
hWndParent = WindowFromPoint(pt);

if(GetWindowText(hWndParent, buff, nMaxCount))
        printf("%s",buff);
else
        printf("null");

Code:

---

HelloWorld.obj : error LNK2001: unresolved external symbol __imp__GetWindowTextA
@12
HelloWorld.obj : error LNK2001: unresolved external symbol __imp__WindowFromPoin
t@8
HelloWorldImp.dll : fatal error LNK1120: 2 unresolved externals

Is this just not supported in JNI or what? I'm totally lost here, so any help would be greatly appreciated. Thanks!

Does anyone have any experience with GetWindowText() and other functions of that sort with JNI?

Have you built a JNI DLL exporting the API functions you want to use?

That's when the compiler starts to whine at me...What's weird is when I try to compile the .cpp in Visual C++ it compiles fine, but when I try to compile in the command prompt using cl, it gives me those link errors
