How to handle command line arguements from simple MFC application ?

m_lpCmdLine Corresponds to the lpCmdLine parameter passed by Windows to WinMain. Points to a null-terminated string that specifies the command line for the application. Use m_lpCmdLine to access any command-line arguments the user entered when the application was started. m_lpCmdLine is a public variable of type LPTSTR.

Code ex.

BOOL CMyApp::InitInstance()
{
// ...

if (m_lpCmdLine[0] == _T('\0'))
{
// Create a new (empty) document.
OnFileNew();
}
else
{
// Open a file passed as the first command line parameter.
OpenDocumentFile(m_lpCmdLine);
}

// ...
}
