Tomasz,
This final note (famous last words) is to let you know that I have
succeeded in making a DLL that gets rid of AutoIt in my Example
Flexible Parameters program. In addition, I added the state of the
modifier keys (shift, alt, control) to my general mouse button states.
Everything turned out to be "reasonably" easy except one thing --the
original problem. It took me two days of research and experimentation
to finally make that work. I turns out that even though it was easy
to save and restore to position of the scroll bar, the data items in
the window are not affected (they are not internally coupled to the
scroll bar position so do not scroll with it). I did a lot of
searching on this problem and found that it was a problem that
exasperated many others, and the solution details varied by person. I
tried the various solutions suggested without success. Finally
through "trial and error" I found a solution different from the others
that did work.
After becoming more familiar with how MS does windows internal
operations, I have a new appreciation for what you must have gone
through to bring us the AmiBroker program... I will say no more about
MS... I leave that to you...
I generated 5 Functions so far:
1. Find and bring a Window to the foreground based on its title bar
name (Parameters Window).
2. Get the scroll position of the Parameters Window.
3. Click "Reset all" button of the Parameters Window.
4. Set the scroll position of the Parameters Window.
5. Get the state of the modifier keys.
Based on this, I do not see any burning need to include support for
modifier keys in AFL since a tiny DLL will provide it, and those that
need it are likely building more sophisticated AFL applications.
However, I would not discourage you from adding it either.
If anyone wants to see the actual Function C++ source, I will be happy
to post it here or email it to them. The DLL itself will be available
later as part of my Flexible Params example AFL to be released on the
UKB. As an aside, I also added some nice modular and simple Gfx drawn
button functions to my Flexible Params Example that I will also share
soon. They are very handy to me for showing/hiding information on the
chart. They take advantage of my parameter system to integrate
directly into the parameters for saving their state between AB launches.
Things are moving forward very nicely for me thanks to your very
helpful support.
Best regards,
Dennis
