How to get the command line arguments in MFC applications?

Question

I wish to have a small dialog based application which is passed command line parameters, so, using VC++6 I ran the application wizard and chose an MFC dialog application.

Answer 1

Yes, see CWinApp:ParseCommandLine. Also take a look at the CCommandLineInfo class.

Answer 2

In MFC applications, the entry point function is 'initInstance()', like main() or wmain(). Use CWinApp::m_lpCmdLine in initInstance() to access the command line.

Answer 3

To get the raw command line use the following code (will work on any Win32 / MFC application):

TCHAR *pCommandLine = ::[GetCommandLine()][1];
int nArgc = 0;
LPWSTR *pArgv = ::CommandLineToArgvW(pCommandLine, &nArgc);

nArgc should be 1 when no arguments given and larger than 1 when there are. Then, pArgv1 will be the first argument, and so on...

Answer 4

Use GetCommandLine(), which returns the name of the file being executed, followed by the arguments.

The application member m_lpCmdLine (used like yourApp.m_lpCmdLine) contains only the arguments.

There is also CWinApp::ParseCommandLine() that you may find useful.

Also try the ATL COM wizard to create a non-MFC dialog application (chose the .exe option, not .dll).
