Article
01/07/2021

Returns the type of warning that occurred by using the AnalysisWarningCode enumeration.

Syntax

HRESULT GetWarningCode(
  [out] AnalysisWarningCode *pWarningCode
);

Parameters

pWarningCode [out]: The type of warning that occurred.

Return value

For a description of the return values, see Classes and Interfaces - Ink Analysis.

Examples

The following example shows an outline of an event handler for the _IAnalysisEvents::Results event. The handler checks IAnalysisStatus::IsSuccessful. If the analysis operation generated warnings, the handler iterates through the collection of IAnalysisWarning objects.

// _IAnalysisEvents::Results event handler.
STDMETHODIMP CMyClass::Results(
    IInkAnalyzer *pInkAnalyzer,
    IAnalysisStatus *pAnalysisStatus)
{
    // Check the status of the analysis operation.
    VARIANT_BOOL bResult = VARIANT_FALSE;
    HRESULT hr = pAnalysisStatus->IsSuccessful(&bResult);

    if( SUCCEEDED(hr) )
    {
        if( bResult )
        {
            // Insert code that handles a successful result.
        }
        else
        {
            // Get the analysis warnings.
            IAnalysisWarnings* pAnalysisWarnings = NULL;
            hr = pAnalysisStatus->GetWarnings(&pAnalysisWarnings);
            if (SUCCEEDED(hr))
            {
                // Iterate through the warning collection.
                ULONG warningCount = 0;
                hr = pAnalysisWarnings->GetCount(&warningCount);
                if (SUCCEEDED(hr))
                {
                    IAnalysisWarning *pAnalysisWarning = NULL;
                    AnalysisWarningCode analysisWarningCode;
                    for (ULONG index=0; index<warningCount; index++)
                    {
                        // Get an analysis warning.
                        hr = pAnalysisWarnings->GetAnalysisWarning(
                            index, &pAnalysisWarning);

                        if (SUCCEEDED(hr))
                        {
                            // Get the warning code for the warning.
                            hr = pAnalysisWarning->GetWarningCode(
                                &analysisWarningCode);

                            if (SUCCEEDED(hr))
                            {
                                // Insert code that handles each
                                // analysis warning.
                            }
                        }

                        // Release this reference to the analysis warning.
                        if (pAnalysisWarning != NULL)

                        }

                }
