Changing Background color of 3 Party App

[Gregery D Engle]

We are wanting to setup a test environment for Users of our
MRP Software. The problem is that our MRP Software doesn't
fully support a test environment, and there really is no
way of telling that your in a test environment other than
of course the data will be different.

With this in mind you can see that huge problems can happen
if a user thinks they are in a test environment and they are
actually on the live system.

I am wanting to somehow change the background color of
the test system.

I plan on doing this, if this is possible.

a& = SHELL(TestMRPPath$)

***** Somehow get the Hwnd from a&

subclass the Hwnd

Process WM_PAINT (If I'm correct), would I just create a
different brush?

then send everything back to the hwnd when done changing the color

first step is how do I get the hwnd from the processID?

I can't simply do a GetWindowText from EnumWindows because both
the Test Version and the Live Version can be opened at the same
time.

Any ideas?

To retrieve a top-level window of shelled process is very simple:
CreateProcess returns ProcessId (inside PROCESS_INFORMATION); EnumWindows + GetWindowThreadProcessId.

But to change a brush is more difficult (another process).
Much easy simply to change a title (SetWindowText should work through processes).
