OleRun (Windows CE 5.0)
This function puts an OLE compound document object into the running state.
WINOLEAPIOleRun(LPUNKNOWNpUnknown);
Parameters
- pUnknown
[in] Pointer to the IUnknown interface on the object, with which it will query for a pointer to the IRunnableObject interface, and then call its IRunnableObject::Run method.
Return Values
The following HRESULT values can be returned.
| Value | Description |
|---|---|
| S_OK | The object was placed in the running state. |
| OLE_E_CLASSDIFF | The source of an OLE link was converted to a different class. |
| E_INVALIDARG | The function failed. |
| E_OUTOFMEMORY | The function failed. |
Remarks
Passing invalid (and under some circumstances NULL) pointers into this function causes an unexpected termination of the application.
The OleRun function puts an object in the running state.
The implementation of OleRun was changed in OLE 2.01 to coincide with the publication of the IRunnableObject interface.
You can use OleRun and IRunnableObject::Run interchangeably.
OleRun queries the object for a pointer to IRunnableObject.
If successful, the function returns the results of calling the IRunnableObject::Run method.
The implementation of OleRun in earlier versions of OLE differs from that described here.
