IsStringSupported function (recapis.h)

Returns a value that indicates whether a word, date, time, number, or other text that is passed in is contained in the dictionary.

The results of this test depend on the factoid setting.

Syntax

HRESULT IsStringSupported(
  HRECOCONTEXT hrc,
  ULONG        wcString,
  const WCHAR  *pwcString
);

Parameters

hrc

The handle to the recognizer context.

wcString

The count, in Unicode (wide) characters, of pwcString.

pwcString

The Unicode (wide) characters to test.

Return value

This function can return one of these values.

Return code Description
S_OK
Success.

This function also returns S_OK if the recognizer does not support this function.

E_OUTOFMEMORY
Unable to allocate memory to complete the operation.
S_FALSE
The string is not supported.
E_POINTER
One of the parameters is an invalid pointer.
E_FAIL
An unspecified error occurred.
E_INVALIDARG
An invalid argument was received.

Remarks

This function is optional.

The results of this test depend on the factoid setting. For example, if the factoid setting is set to default, then "hello","555-1234", and "10/19/2002" all return S_OK. However, if the factoid is set to TELEPHONE, only "555-1234" returns S_OK, the others return S_FALSE. For more information about factoids, see Supported Factoids from Version 1.

Note that this function should take into consideration any information specified in SetTextContext when returning a value. For example, if the recognizer receives calls to SetTextContext ("http:", "") and receives a URL factoid, SetFactoid ((!IS_URL)) then IsStringSupported("www.microsoft.com") should return S_FALSE because it is missing the "//".

The COERCE flag has no effect on IsStringSupported.
