The archive at
http://www.powerbasic.com/support/downloads/files/win32api.zip
contains include files for the PowerBASIC compiler. The numeric values
of most Win32 API constants are contained in the file win32api.inc. To
translate from the hex representation used by PowerBASIC (and Visual
Basic) to the C-like representation used by JAWS, replace the "&h"
prefix with the "0x" prefix.
Note that many SendMessage calls to standard Windows controls have been
wrapped in functions of the Homer Script Library, available at
http://www.EmpowermentZone.com/kitsetup.exe
or for a manual install
http://www.EmpowermentZone.com/kitsetup.zip
For example, below is the ButtonClick function in Homer.jss. It
essentially sends a mouse click message to the window specified by a
handle, which may be a button or another control. This may be worth
trying in the Java applet you mentioned if you have not already solved
the problem of setting focus there. These Homer functions default to the
window with focus if a 0 is passed as a parameter rather than a valid
window handle.
Hope this helps,
Jamal
Int Function ButtonClick(Handle h)
;Activate a button
Var
Int BM_CLICK
If !h Then
Let h = GetFocus()
EndIf
Let BM_CLICK=245
Return SendMessage(h, BM_CLICK, 0, 0)
EndFunction
