SHAutoComplete & current working directory? - windows

Question

I am using SHAutoComplete with the SHACF_FILESYSTEM option. The problem is, files relative to the current working directory are not autocompleted. There are no suggestions for relative paths -- for example, the working directory contains settings.txt, but I can type "settings" into the edit and nothing appears.
Is there a relatively easy solution? Or do I have to override the autocomplete behaviour with some own lookup?
Thank you in advance!

Please take a look at the documentation at:

You need to explicit specify the "Current directory" as an option. This must be done throu IACList2::SetOptions http://msdn.microsoft.com/en-us/library/windows/desktop/bb776376
==> You must use the COM interface, to set the options you want... Here is an example:
HRESULT EnableAutoComplete(HWND hWndEdit, LPWSTR szCurrentWorkingDirectory = NULL, AUTOCOMPLETELISTOPTIONS acloOptions = ACLO_NONE, AUTOCOMPLETEOPTIONS acoOptions = ACO_AUTOSUGGEST, REFCLSID clsid = CLSID_ACListISF)
{
IAutoComplete *pac;
HRESULT hr = CoCreateInstance(CLSID_AutoComplete,
NULL,
CLSCTX_INPROC_SERVER,
IID_PPV_ARGS(&pac));
if (FAILED(hr))
{
return hr;
}
IUnknown *punkSource;
hr = CoCreateInstance(clsid,
NULL,
CLSCTX_INPROC_SERVER,
IID_PPV_ARGS(&punkSource));
if (FAILED(hr))
{
pac->Release();
return hr;
}
if ( (acloOptions != ACLO_NONE) || (szCurrentWorkingDirectory != NULL) )
{
IACList2 *pal2;
hr = punkSource->QueryInterface(IID_PPV_ARGS(&pal2));
if (SUCCEEDED(hr))
{
if (acloOptions != ACLO_NONE)
{
hr = pal2->SetOptions(acloOptions);
}
if (szCurrentWorkingDirectory != NULL)
{
ICurrentWorkingDirectory *pcwd;
hr = pal2->QueryInterface(IID_PPV_ARGS(&pcwd));
if (SUCCEEDED(hr))
{
hr = pcwd->SetDirectory(szCurrentWorkingDirectory);
pcwd->Release();
}
}
pal2->Release();
}
}
hr = pac->Init(hWndEdit, punkSource, NULL, NULL);
if (acoOptions != ACO_NONE)
{
IAutoComplete2 *pac2;
hr = pac->QueryInterface(IID_PPV_ARGS(&pac2));
if (SUCCEEDED(hr))
{
hr = pac2->SetOptions(acoOptions);
pac2->Release();
}
}
punkSource->Release();
pac->Release();
}
you can call it via:
wchar_t szCurDir[MAX_PATH];
GetCurrentDirectoryW(MAX_PATH, szCurDir);
EnableAutoComplete(m_txtBox1.m_hWnd, szCurDir, ACLO_CURRENTDIR);
