ITypeLib::FindName method (oaidl.h)

  • Article

Finds occurrences of a type description in a type library. This may be used to quickly verify that a name exists in a type library.

Syntax

HRESULT FindName(
  [in, out] LPOLESTR  szNameBuf,
  [in]      ULONG     lHashVal,
  [out]     ITypeInfo **ppTInfo,
  [out]     MEMBERID  *rgMemId,
  [in, out] USHORT    *pcFound
);

Parameters

[in, out] szNameBuf

The name to search for.

[in] lHashVal

A hash value to speed up the search, computed by the LHashValOfNameSys function. If lHashVal = 0, a value is computed.

[out] ppTInfo

An array of pointers to the type descriptions that contain the name specified in szNameBuf. This parameter cannot be null.

[out] rgMemId

An array of the found items; rgMemId[i] is the MEMBERID that indexes into the type description specified by ppTInfo[i]. This parameter cannot be null.

[in, out] pcFound

On entry, indicates how many instances to look for. For example, *pcFound = 1 can be called to find the first occurrence. The search stops when one is found.

On exit, indicates the number of instances that were found. If the in and out values of *pcFound are identical, there may be more type descriptions that contain the name.

Return value

This method can return one of these values.

Return code Description
S_OK
Success.
E_INVALIDARG
One or more of the arguments is not valid.
E_OUTOFMEMORY
Insufficient memory to complete the operation.

Remarks

Passing *pcFound = n indicates that there is enough room in the ppTInfo and rgMemId arrays for n (ptinfo, memid) pairs. The function returns MEMBERID_NIL in rgMemId[i], if the name in szNameBuf is the name of the type information in ppTInfo[i].
