mfc >> Adding support for GetObject in a MFC exe

by Q2xpbnQ » Mon, 24 Nov 2003 01:01:05 GMT

I would like to use GetObject in vb/vb script to access a running instance of my com object

So I spent a huge amount of time trying to get a dialog based MFC .exe generate by the MFC Appwizard to register it self in the running object table (ROT). I have found many samples that work with MDI / SDI but not Dialog based MFC projects.

Here is a post for SDI http://communities2.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.vc.mfc&mid=1b88790b-4ff4-4546-a54e-ed5c43b784c

I tried the following

DWORD dwCookie=0

HRESULT hr=RegisterActiveObject(GetControllingUnknown()
MyApp_CLSID, ACTIVEOBJECT_WEAK, &dwCookie)

In the Dialog base application the GetControllingUnknown() function seems to fail
Also

RegisterActiveObject(GetInterface(&IID_IUnknown)
CCalcDlg::guid, NULL, & dwCookie)

The GetInterface(&IID_Iunknown) does not seem to work properly

At this point I decide there must be something simple that I am missing
