MFC中创建console窗口

HANDLE m_hConsoleOutput = NULL;
if (!m_hConsoleOutput)
{
AllocConsole();
m_hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
char str[512] = "start Console Log...\n";
WriteConsole(m_hConsoleOutput, str, strlen(str), NULL, NULL);
}
if (m_hConsoleOutput)
{
char str[512] = "destroy console...\n";
WriteConsole(m_hConsoleOutput, str, strlen(str), NULL, NULL);
CloseHandle(m_hConsoleOutput);
FreeConsole();
}
