Re: [perl-win32-gui-users] Merging Win32::GUI and Win32::GuiTest. (Was: Attaching to a window created by some other application)

[Jeremy White]

And finally, to make function work with windows owned by other process:

void
GetItem(handle,item, subitem=0)
    HWND handle
    int item
    int subitem
ALIAS:
    Win32::GUI::ListView::ItemInfo = 1
PREINIT:
    LV_ITEM lv_item;
    char pszText[1024];
PPCODE:
->    int thisproc = GetCurrentProcessId();
->    int calledproc = 0;
->    GetWindowThreadProcessId( handle, &calledproc );

Imagine this situation. A list view is created in a different thread from 
the 'main' thead. The main thread then calls GetItem for the listview that 
was created in the other thread. Would this still work? I guess what I'm 
trying to say is that if we do make all Win32::GUI function calls work 
across processes, they should also work across all threads within the same 
process that is running Win32::GUI.

Cheers,
