I have not been able to get any function inside ComCtl32.dll to be found. Here is an example function call. I've tried many variations and on 2 computers, so I believe it is a bug.

There is no function called ListView_SetSelectionMark in comctl32.dll

Look at http://msdn2.microsoft.com/en-us/library/ms671362.aspx

MS commctrl.h says:
#define ListView_SetSelectionMark(hwnd, i) \
(int)SNDMSG((hwnd), LVM_SETSELECTIONMARK, 0, (LPARAM)(i))

#define LVM_SETSELECTIONMARK (LVM_FIRST + 67)

#define LVM_FIRST 0x1000 // ListView messages

Hence: should be something like:
SendMessage 0x1000+67,0, 1, , ahk_id %HWND%

In other words, Microsoft describes them as macro functions, meaning they are not real functions to be called with DllCall, but rather wrappers, syntax sugar hiding, under a familiar look, some barbaric method... Wink

These macros cannot be used outside the C-family languages.
As JGR advises, you have to use SendMessage (often documented at the same place).
