Easy: Append line to CStdioFile

Here's an easy one for you experts...
I need to open a file and append one line to it. I tried the following code, but it just overwrites the text in the file:

CStdioFile objFile( (LPCTSTR) m_strCurrentExportFile,  CFile::modeCreate |CFile::modeWrite |CFile::typeText );
         
objFile.SeekToEnd();
objFile.WriteString( (LPCTSTR) strOutput );      
objFile.Close();

Hi! Yor modes for opening file is incorrect. CFile:modeCreate - truncate file to 0 if it already exist. You must check if file to append already exist and add CFile::modeCreate if it isn`t true.
