In your dialog based application create the main dialog for taking the user input for id and password.
Check and validate the password. If they are correct,

if(bIsPasswordCorrect)
{
CMYDlg myDlg;
myDlg.DoModal();
}
set bIsPasswordCorrect to true only if the credentials are correct.

You need to google first, if you have "It's urgent please" mentioned in your question.

Did you make your dialogs(with CDialog or CreateWindow)?

Hi,

I am working on VS 2005 on Vista platform.

I have an mobile data card which exposes an Modem Port and this port appears as an device entry under "Modems" in the Device Manager.

In addition to this, the device has another port which i figured out by scanning through the registry and this port does not appear in the device manager.
This port appears in the list of available ports displayed by HyperTerminal and also in PortMon and I can connect and talk to the device via HyperTerminal.

But in my application when I try to do an CreateFile with that port name, the call fails with GetLastError() returning 2.

    TCHAR szPortName[MAX_PATH]=_T("");
_tcscpy(szPortName, _T("\\\\.\\"));
_tcscat(szPortName, _T("COM6:");    //assume the non-exposed port is COM6.

HANDLE hDeviceFile = CreateFile(szPortName,
    GENERIC_READ | GENERIC_WRITE,
    0,
    NULL,
    OPEN_EXISTING,
    0,
    NULL);
DWORD dwReturn = GetLastError();

Is there something wrong in the CreateFile() function call above.
Or is it that Vista allows only ports that are expose/displayed in the Device Manager for an Device to be used by an application?

Found the problem.
I was specifying Port Name as _T("COM6:") while the correct was is _T("COM6") i.e, without the colon at the end.

You can't. C++ knows nothing of this sort of thing. You'll need to call NetUserModalsGet() to get such information.

You could use a decompiler like Reflector[^] if the binary was built with managed code (and wasn't obfuscated[^]).

With a Win32 DLL, well, good luck.

You need to probably restructure your problem. First: Do you really need to display 1 lac lines in the list box...
I don't really think that any user for your application would be really interested in reading or going through that many lines of text at a time.
If not can you use some kind of paging mechanism rather than reading the whole file. Only read the number of records that you can display at a time.

You need to google first, if you have "It's urgent please" mentioned in your question.
