You may try this !

#define MAX_AVAIL_COM_PORTS 250
int i = 0;
char chTemp[3];
CString strCOMPort;
HANDLE hndCurrCOMPortObj;

for (i = 0; i < MAX_AVAIL_COM_PORTS; i ++)
{
itoa (i + 1, chTemp, 10);
strCOMPort = "COM";
strCOMPort += chTemp;
// Create handle for selected COM port and check its Avilability
hndCurrCOMPortObj = CreateFile (strCOMPort,GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, 0, 0);

if (INVALID_HANDLE_VALUE == hndCurrCOMPortObj)
{
strCOMPort += strCOMPort + " port not available !!";
AfxMessageBox (strCOMPort);
}
else
{
strCOMPort += " port Available !!";
AfxMessageBox (strCOMPort);
CloseHandle (hndCurrCOMPortObj);
}
}

It won't work for ports having number >= 10.

I suspected so. Roll eyes | :rolleyes:

Because you must use UNC [^] names for serial ports with number >= 10, e.g. port 12 UNC is \\.\COM12 (you may use always UNC names).

CMenu Item Problem

Dhiraj kumar Saini29-Sep-08 22:33

Dhiraj kumar Saini

29-Sep-08 22:33

I have CMenu Items for a ClsiCtrl Corresponding to certain buttons.

I have kept all the buttons disabled except one.

Now the problem is in CMenu Item List the respective menu items for enabled button is enabled and for the remaining disabled buttons one menu items is being displayed as enabled. WHat can be the reason.

Please help me. My code is as follows:

CMenu mnu;
mnu.LoadMenu(IDR_VLIST_MENU);
CMenu* pSubMenu = mnu.GetSubMenu(0);

if(!m_btnViewDetails.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VLIST_DETAILS, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

if(!m_btnFootPrints.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VLIST_FOOTPRINT, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

if(!m_btnAccept.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VLIST_ACCEPT, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

if(!m_btnInvite.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VLIST_INVITE, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

if(!m_btnDelete.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VISITOR_DELETE, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED );

if(!m_btnIPBlocking.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VLIST_BLOCKIP, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

if(!m_btnDeny.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VLIST_BUSY, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);

pSubMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON ,point.x,point.y,this,0);

In the aboce code
if(!m_btnDelete.IsWindowEnabled())
pSubMenu->EnableMenuItem(ID_VISITOR_DELETE, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED );
is seen as enabled although it should be disabled. m_btnDelete is also disabled.

Thanks in advance

You cannot use CopyFile to copy content of a folder.. Other wise you have to copy all the files in folder one by one..
