Gets the displayable name of the document that contains this document context.

Syntax

HRESULT GetName(
    GETNAME_TYPE gnType,
    BSTR*        pbstrFileName
);

int GetName(
    enum_GETNAME_TYPE  gnType,
    out string         pbstrFileName
);

Parameters

gnType
[in] A value from the GETNAME_TYPE enumeration that specifies the type of name to return.

pbstrFileName
[out] Returns the name of the file.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Remarks

This method typically forwards the call to the GetName method, unless the document context is written to store the document name itself (as the Example show).

Example

The following example shows how to implement this method for a simple CDebugContext object that exposes the IDebugDocumentContext2 interface.

HRESULT CDebugContext::GetName(GETNAME_TYPE gnType, BSTR* pbstrFileName)
{
    HRESULT hr;

    // Check for a valid file name argument.
    if (pbstrFileName)
    {
        *pbstrFileName = NULL;

        switch (gnType)
        {
            case GN_NAME:
            case GN_FILENAME:
            {
                // Copy the member file name into the local file name.
                *pbstrFileName = SysAllocString(m_sbstrFileName);
                // Check for successful copy.
                hr = (*pbstrFileName) ? S_OK : E_OUTOFMEMORY;
                break;
            }
            default:
            {
                hr = E_FAIL;
                break;
            }
        }
    }
    else
    {
        hr = E_INVALIDARG;
    }

    return hr;
}
