IEnumCERTVIEWEXTENSION::GetName method (certview.h)

Article
02/22/2024

The GetName method retrieves the name of the current extension in the extension-enumeration sequence.

The returned extension name is an object identifier (OID) string, as in L"2.5.29.31".

Syntax

HRESULT GetName(
  [out] BSTR *pstrOut
);

Parameters

[out] pstrOut

A pointer to a value of BSTR type that contains the name of the extension.

Return value

C++

If the method succeeds, the method returns S_OK and tat the pstrOut parameter is set to the name of the extension.

To use this method, create a variable of BSTR type, set the variable equal to NULL, and pass the address of this variable as pstrOut. When you have finished using the BSTR, free it by calling the SysFreeString function.

If the method fails, it returns an HRESULT value that indicates the error. For a list of common error codes, see Common HRESULT Values.

VB

The return value is a String that contains the name of the extension.

Remarks

This function is used to retrieve the name of the extension currently referenced by the extension-enumeration sequence.

If the extension-enumeration sequence is not referencing a valid extension, GetName will fail. Use one of the following methods to navigate through the enumeration:

IEnumCERTVIEWEXTENSION::Reset: Moves to the next extension in the enumeration sequence.
IEnumCERTVIEWEXTENSION::Next: Moves to the next extension in the enumeration sequence.
IEnumCERTVIEWEXTENSION::Skip: Skips a specified number of extensions.

Examples

BSTR  bstrExtName = NULL;

// pEnumExt is previously instantiated IEnumCERTVIEWEXTENSION object
hr = pEnumExt->GetName(&bstrExtName);
if (S_OK == hr)
    printf("Extension name is: %ws\n", bstrExtName);
else
    printf("GetName failed: %x\n", hr);

// free memory when done
if (NULL != bstrExtName)
    SysFreeString(bstrExtName);
