How to set command line argument in dialog based program?

Use GetCommandLine function as following:

BOOL CColdBootApp::InitInstance()
{
// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need.
LPTSTR lCmd = ::GetCommandLine();

// MessageBox(NULL, lCmd, L"", MB_OK);

if(_tcscmp(lCmd, L"/nobar")==0)
{
//cold boot
// MessageBox(NULL, L"Cold boot now!", L"", MB_OK);
ColdReboot();
return FALSE;
}

CColdBootDlg dlg;
m_pMainWnd = &dlg;

int nResponse = dlg.DoModal();
...


}

(
CString aa = ::GetCommandLine();
aa.MakeLower();
BOOL bShowBar = FALSE;
BOOL bDoAsk = FALSE;
if(aa.Find(L"/nobar")==-1)
bShowBar = TRUE;
else
bShowBar = FALSE;

if(aa.Find(L"/noask")==-1)
bDoAsk = TRUE;
else
bDoAsk = FALSE;

if(bDoAsk)
{
if(MessageBox(NULL, L"Are you sure?", L"Cold Boot", MB_YESNOCANCEL|MB_TOPMOST|MB_ICONEXCLAMATION )!=IDYES)
return FALSE;
else
{
if(!bShowBar)
{
ColdReboot();
return FALSE;
}
}
}else
{
if(!bShowBar)
{
ColdReboot();
return FALSE;
}
}
)
