I am managing exceptions using C++ MFC using the catch(...) option. Is there any way to get more information using this exception handler, more than just "and exception occurred"? Like Windows getLastError() or something?
Any help would be appreciated.

void myProgram
{
CStdioFile file;
CString szPath = _T("Myfile.txt");
CString szData,szError;
bool bFound = false;
int nErrors = 0;
TCHAR szCause[255];
try
{
file.Open(szPath, CFile::modeNoTruncate | CFile::modeReadWrite);
file.SeekToEnd();
while( file.ReadString(szData) && !bFound && !nErrors )
{
if( szData.Find(_T("MyName="),0) >= 0 )
{
someProcessProgram(szData);
bFound = true;
}
}
file.Close();
}
catch( CException* e )
{
e->GetErrorMessage(szCause,255);
e->Delete();
szError.Format(_T("An exception occurred while reading data.\nWindows reports: %s"),szCause);
nErrors++;
AfxMessageBox(szError);
}
catch( std::exception* e )
{
szError.Format(_T("An exception occurred while reading data.\nWindows reports: %s"),e->what());
nErrors++;
AfxMessageBox(szError);
}
catch(...)
{
szError = _T("An exception occurred while reading data.");
nErrors++;
AfxMessageBox(szError);
}
}
