Enumeration of Windows Taskbar

[csda1]

I am looking for a method to use within Alpha Five to list the handles or names of the windows in the Windows taskbar, just those windows, nothing else.

I think it can be done in Alpha calling some windows APIs, but it is not that straightforward, and there may be some gotchas with Alpha's API interface.

Perhaps someone else has an idea of an easier way it could be done?

Thanks!

Re: Enumeration of Windows Taskbar

Is this of any help? (as a starting point?)

all_win = sys_id_enum()
real_win = ""
for each foo in all_win
	if sys_id_position_get(foo) = "Taskbar" .or. sys_id_position_get(foo) = "Desktop"
		real_win = real_win+foo+crlf()
	end if
next
ui_msg_box("",real_win)
end

? real_win
= Alpha Five - [Code Editor]

The GDI+ Window listings are not visible to me. The Dell listings are in the QuickLaunch area.

Hi Stan,

Is this of any help? (as a starting point?)

Interesting difference from my code I was trying. I don't have maximized windows, so I was always getting size numbers in my tests using similar code. I had eliminated all windows that have 0 height or 0 width. In addition, I can get rid of all of Alpha's Xdialog and Alpha MDI windows (with a small risk of eliminating a real window that has the same name) from the list, but that still left me with a lot of window processes (many on the system tray). I did try and see what happened in minimizing, maximizing and restoring the "non-windows" programs, but that brought up windows that I could not eliminate.

Just to be clear, I'm not talking about programs minimized to the taskbar, but all application windows that you would see if you used Alt-Tab repeatedly.

The main issue with the windows API methods is the issue of the method to do a Win API callback function within Alpha. I don't believe it is documented how to do this in Alpha, and may be impossible to do (although I could definitely pass a function pointer, but it may not be compatible to Windows)

Dave - That link was not useful, other windows API pages do give some answers, but they all involve function callbacks.

Re: Enumeration of Windows Taskbar

Using a IsWindowVisible API, I can eliminate most of the undesired windows from the Sys_ID_Enum() function. I'm not sure if there are any real gotchas, but it looks OK.

For my current need, I think this will work just find.

If it could enumerate the Top level Window's windows that would be great great!

But it would be really great if Alpha Five could handle API function callbacks, which at least according to this, it does not.
