Url with dde server

09 Apr 2016, 05:02

I'd like to get seans dde code to work with my firefox. It works without a problem at a windows 7 pc at work, but on my win10 at home it only gets the url of the "about:" sites of firefox

Code: Select all

browser:="Firefox"
msgbox, %  FF_RetrievePageName(browser)
return 

FF_RetrievePageName(browser)
   {
   DllCall("DdeInitializeW","UPtrP",idInst,"Uint",0,"Uint",0,"Uint",0)
   ; CP_WINANSI = 1004   CP_WINUNICODE = 1200
 
  CP_WIN:=A_IsUnicode?1200:1004
   hServer := DllCall("DdeCreateStringHandleW","UPtr",idInst,"Str",browser,"int",cp_win)
   hTopic  := DllCall("DdeCreateStringHandleW","UPtr",idInst,"Str","WWW_GetWindowInfo","int",cp_win)
   hItem   := DllCall("DdeCreateStringHandleW","UPtr",idInst,"Str","0xFFFFFFFF","int",cp_win)
   hConv := DllCall("DdeConnect","UPtr",idInst,"UPtr",hServer,"UPtr",hTopic,"Uint",0)
   ; CF_TEXT = 1      CF_UNICODETEXT = 13
   CF_TEXT :=1
  
   hData := DllCall("DdeClientTransaction","Uint",0,"Uint",0,"UPtr",hConv,"UPtr",hItem,"UInt",   CF_TEXT,"Uint",0x20B0,"Uint",10000,"UPtrP",nResult)
; seems to fail at hData

   sData := DllCall("DdeAccessData","Uint",hData,"Uint",0,"str")
 msgbox, % hserver " " hTopic  " " hItem " "  hConv  " " hData " sData" sData
   DllCall("DdeFreeStringHandle","UPtr",idInst,"UPtr",hServer)
   DllCall("DdeFreeStringHandle","UPtr",idInst,"UPtr",hTopic)
   DllCall("DdeFreeStringHandle","UPtr",idInst,"UPtr",hItem)
   DllCall("DdeUnaccessData","UPtr",hData)
   DllCall("DdeFreeDataHandle","UPtr",hData)
   DllCall("DdeDisconnect","UPtr",hConv)
   DllCall("DdeUninitialize","UPtr",idInst)
   result:=StrGet(&sData,"cp0")
   return result
   }

Maybe have a look at this extended and updated version by atnbueno:
Get the URL of the current (active) browser tab

Thank you very much for testing!
Could it be x86 / x64 problem? At work (code is working) i've a x64 hardware/windows. But i don't believe this..
I know i used this code some time ago...before win10 ...i think it was xp. :-)
I also deactiveted my addons without improvement.
