Any sample of AccessibleObjectFromWindow ? (IID_IAccessible with compiler error)

[alex100]

Hi
I am trying to make a kind of screen reader using gcc (mingw) Wxwidgets in windows 7

To start, I am trying to use and test AccessibleObjectFromWindow win function like this:

#include <Oleacc.h>
#include <OleAuto.h>
//Also included the related libs on the project


void testDialog::OnButton1Click(wxCommandEvent& event)
{
    IAccessible* accessibleFrame = NULL;
    if (S_OK != AccessibleObjectFromWindow((HWND) GetHWND(), OBJID_CLIENT,IID_IAccessible, (void**) & accessibleFrame))
    {
        return;
    }
}

Then I will call get_accName..


But compiler says this:

C:\test\testMain.cpp|96|undefined reference to `IID_IAccessible'|


I already tried to use &IID_IAccessible instead but compiler says:

C:\test\testMain.cpp|96|error: invalid initialization of reference of type 'const IID& {aka const _GUID&}' from expression of type 'const IID* {aka const _GUID*}'|
c:\mingw\include\oleacc.h|219|error: in passing argument 3 of 'HRESULT AccessibleObjectFromWindow(HWND, DWORD, const IID&, void**)'|

Please, could you help me?

Many thanks

Alex

IID_IAccessible resides in libuuid library. And when posting code, please use [code][/code] tags.
