Error Indication Support

There is a built-in, simple, and flexible mechanism that allows you to specify incorrect words or spelling errors, display them with a red curved line under the text, and show a list of suggested corrections in the context menu for each word.

Sample code:

BOOL CCustomEditCtrl::IsCorrectWord(
	const CString& strWord, 
	int iWordStart, 
	int nColorBlockID) const
{
	UNREFERENCED_PARAMETER(iWordStart);
	UNREFERENCED_PARAMETER(nColorBlockID);
		
	if (theApp.m_lstCustomDictionary.Find(strWord) != NULL)
	{
		return TRUE;
	}
	
	if (theApp.m_lstIgnoreSpelling.Find(strWord) != NULL)
	{
		return TRUE;
	}
		
	// Used in C++ example:
	return 	strWord != _T("CMyClaass") && 
		strWord != _T("toobar") && 
		strWord != _T("examle");
}

void CCustomEditCtrl::GetWordCorrections(
	const CBCGPEditErrorIndicator& wordInfo, 
	CStringArray& arSuggestions, 
	CStringArray& arCustomActions) const
{
	arSuggestions.RemoveAll();	
	
	if (wordInfo.m_nColorBlock == -1)
	{
		// Default text, no suggestions.
		return;
	}
	
	if (wordInfo.m_strWord == _T("toobar"))
	{
		arSuggestions.Add(_T("toolbar"));
		arSuggestions.Add(_T("toolbox"));
		arSuggestions.Add(_T("2 bars"));
	}
	else if (wordInfo.m_strWord == _T("examle"))
	{
		arSuggestions.Add(_T("example"));
	}
	
	arCustomActions.Add(_T("&Ignore All"));
	arCustomActions.Add(_T("&Add to Dictionary"));
}
