How do I capture a picture from an active window on the net?

I want to capture an image on the net and convert it to a number array using LabView.

How automatic do you want the process to be? You could always do a screen capture manually, paste it into paint, save it as a BMP and then open the BMP in LV.

What exactly are you trying to do?

That's exactly what I want to do. I can save the picture in LabView and convert it to a number array for use. But, I can't seem to capture a certian active window. I don't see a url. It appears to be inbedded in some sort of source code. Is there a way to take a snapshot (or similar) of the "active window" without knowing the url? If not, is there a way to find the specific address?

Well, on my PC pressing Fctn - Print Screen. Captures whatever is on my screen and saves it to the clipboard. On my keyboard, Print Screen (abbreviated "Prt Sc") is the same as the "Insert" key.

Of course you might need to clean-up the image to trim out the window borders and such but this should always work. Is the web site you are accessing a publically accessible one? If so I would be willing to look at it and see what I can find.

But I have never seen Fctn-PrintScreen fail to capture what I was looking at...

I'm fairly new to LV and doing my best. The site is PoGo.com going to the Poppit game. I am looking to capture a picture and write a "cheat program" for this online game. This will be my second one and I find this to be a little more chalenging than the first for me. Basically, the game is a 2D array of balloons (colors) and the object is to eliminate all balloons. As you pop a grouping the others will float up and adjust themselves according to physics. I have been able to capture any web page with a URL using the Invoke Node Web Browser/Get Image, but this page that is inside an existing program seems to be eluding me. If you believe there is a better/faster/more reliable way to capture an image online, please let me know. Maybe, i
f at all possible, we could actually email instead of going through NI.com, let me know. Thanks for your help.

Hi,

Seems that the are doing everything to prevent automated play of the
game.....


Anyway, you'll have to figure out a way open the link inside a activex
component. Then you can capture the image using the invoke node (of the LV
control, not of the axtivex) GetImage.

Otherwise, you'll have to use windows (GDI) api's, like BitBlt, GetDC and
GetDIBits. To know how to use them, you'll have to study C, Visual Basic,
etc. code, and the windows SDKs as well. (This might not be worth the
effort...)

Regard,

Wiebe.
