IBindCtx::RevokeObjectParam

Removes the specified key and its associated pointer from the bind context's string-keyed table of objects. The key must have previously been inserted into the table with a call to IBindCtx::RegisterObjectParam.

HRESULT RevokeObjectParam(
  LPOLESTR pszKey  //Pointer to the key to be revoked
);

Parameter

pszKey: [in] Pointer to a zero-terminated wide character string (two bytes per character) containing the key to remove. Key string comparison is case-sensitive.

Return Values

S_OK: The specified key was successfully removed from the table.
S_FALSE: No object has been registered with the specified key.

Remarks

A bind context maintains a table of interface pointers, each associated with a string key. This enables communication between a moniker implementation and the caller that initiated the binding operation. One party can store an interface pointer under a string known to both parties so that the other party can later retrieve it from the bind context.

This method is used to remove an entry from the table. If the specified key is found, the bind context also releases its reference to the object.
