I've been trying to use the Windows Api with darkbasic pro. bu i noticed that many of them require for the current program's window handle to be passed as an argument.

To get the window handle i use the folloing code

+ Code Snippet

load dll "user32",1
Global Handle As integer
Handle=call dll(1,"GetForegroundWindow")

This code requires for the program's window to be the one focused.
Althogh this might be true for most case it is not for certain.

Is there a better way to do this?.

It is logic to choose with your heart

You should always used the one in g_pGlob (g_pGlob->hWnd). Whilst GetActiveWindow works, it is slow (and why call a function to get a windows handle when its already present? Unless, your not doing a plug-in).

Walk softly... and carry a big gun...

You can use FindWindow instead.

+ Code Snippet

title as string
title = "dbpro window"
set window title title

load dll "user32.dll",1
hwnd = call dll(1,"FindWindowA",0x0,title)
delete dll 1

print hwnd
wait key

Get it from DBPro:

+ Code Snippet

` Do it the 'usual' way
HWND as dword

load dll "user32.dll", 1
HWND = call dll(1, "GetActiveWindow")
delete dll 1

print "User32.dll = "; hex$(HWND)

` Now do it my way
print "Core.dll   = "; hex$(GetDBProHWND())

print "Done"

wait key
end


function GetDBProHWND()
   local i as integer
   local Core as dword
   local HWND as dword

   for i=1 to 256
      if dll exist(i) = 0
         load dll "DBProCore.dll", i
         Core = call dll(1, "?GetGlobPtr@@YAKXZ")
         delete dll 1

         inc Core, 600
         HWND = *Core

         exit
      endif
   next i
endfunction HWND
