SYMPTOMS
========
If the OLE .DLL files are not initialized with a call to AfxOleInit(),
subsequent OLE calls will fail. For 32-bit MFC applications, debug output sent
to a debugging window may show these errors:
Throwing exception of type COleException
sCode = 0x8007000E E_OUTOFMEMORY
- or -
sCode = 0x80030008 STG_E_INSUFFICIENTMEMORY
For 16-bit MFC applications, debug output may show:
Throwing exception of type COleException
sCode = 0x80000002 E_OUTOFMEMORY
- or -
sCode = 0x80030008 STG_E_INSUFFICIENTMEMORY
RESOLUTION
==========
AfxOleInit() calls OleInitialize(LPMALLOC), which sets the task memory allocator
used by OLE. If this is not done, OLE cannot perform memory allocations and any
OLE calls will fail. Placing a call to AfxOleInit() in the InitInstance() of an
MFC application will fix this problem. The first few lines from the
InitInstance() of HIERSVR (MFC OLE sample provided with Visual C++) below, shows
the proper syntax for calling AfxOleInit().
Sample Code
-----------
/* Compile options needed: standard MFC project
*/
BOOL CServerApp::InitInstance()
{
// OLE 2.0 initialization
if (!AfxOleInit())
{
AfxMessageBox(IDP_OLE_INIT_FAILED);
return FALSE;
}
... function continues ....
STATUS
======
This behavior is by design.
