Re: Turning on/off caps lock, num lock and scroll lock

Try the knowledge base for article Q177674. It's old but should help you out.

You first need to query the state and then depending upon the OS, use different API calls to toggle the state. Not as simple as say 'Turn on NUMLOCK', unfortunately.

I use such code to turn Capslock on/off in WinNT/2000:

// Description :
// Turn CapsLock on/off
// Source: MSDN topic "keybd_event"
void SetCapsLock(BOOL bState)
{
BYTE keyState[256];

GetKeyboardState((LPBYTE)&keyState);
if( (bState && !(keyState[VK_CAPITAL] & 1)) ||
(!bState && (keyState[VK_CAPITAL] & 1)) )
{
// Simulate a key press
keybd_event( VK_CAPITAL,
0,
KEYEVENTF_EXTENDEDKEY | 0,
0 );

// Simulate a key release
keybd_event( VK_CAPITAL,
0,
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
0);
}
}

File size in FTP server...

27-Dec-01 1:22

I've got a problem...
I've used "CFtpConnection::OpenFile()" to open a file at a FTP server. It returns a CInternetFile*. I've called it "pInternetFile"...
My problem is that I'm trying to use "pInternetFile -> GetLength()" to retrieve its size in bytes, but the function always returns 0 !
What's wrong ?

There is a good chance that your hardware guy connected the PC-speaker to your sound-card. I am not sure about this, but it seems a likely possibility.

I have Win 2000. The beep comes out of my PC speaker and not through my speakers [I don't have speakers though I have a sound card. I use ear-phones]

I physically disconnect the speaker on every PC I use, and Beep works through my soundcard ( possibly as a result ?? )

Well,that's confusing. Maybe, it's a feature in your motherboard that when it finds the speaker disconnected it connects to the sound-card

Track a Machine

26-Dec-01 22:14

Hi,

How is it possible to tack the monitor of a client machine in a networking environment from another client machine?

Thanks

Re: Track a Machine

26-Dec-01 22:30

:-DHello,
Ya it's possible. But I what way do you want ? by programming or by any available tool ?

If you want to do it by programming then you will have to learn socket programming.
And if you want some readymade utility then WinVNC is there.You can capture online desktop of any client machine in network.

MprAdminMIBEntryGet is failing!!!!

Nish Nishant26-Dec-01 21:18

26-Dec-01 21:18

Hello guys

I can't get MprAdminMIBEntryGet to work properly Frown | :-(

HANDLE _hMibSrv;  
MIB_OPAQUE_QUERY  MibOpaqueQuery; 
PMIB_OPAQUE_INFO  pMibOpaqueInfo = NULL; 
DWORD  dwInSize, dwOutSize, dwResult; 
PMIB_IFTABLE  pIntfTable; 
MibOpaqueQuery.dwVarId = IF_TABLE; 
dwInSize = sizeof( MIB_OPAQUE_QUERY ); 
dwOutSize = 0; 
if(MprAdminMIBServerConnect(NULL,&_hMibSrv)!= NO_ERROR)
{
	cout << "MprAdminMIBServerConnect failed\r\n";
	return -1;
}
dwResult = MprAdminMIBEntryGet ( _hMibSrv,PID_IP,IPRTRMGR_PID, 
(PVOID)&MibOpaqueQuery,dwInSize, 
(PVOID *)&pMibOpaqueInfo,&dwOutSize );

The documentation says that dwResult is either NO_ERROR [which it is not for me Frown | :-(

] or one of the following values

ERROR_ACCESS_DENIED, ERROR_CANNOT_COMPLETE,
ERROR_UNKNOWN_PROTOCOL_ID, ERROR_NOT_ENOUGH_MEMORY

So I put a switch statement to figure out the error :-

if ( dwResult != NO_ERROR )
{			
	switch(dwResult)
	{
	case ERROR_ACCESS_DENIED:
		cout << "1`\r\n";
		break;
//	case ERROR_CANNOT_COMPLETE:
//		cout << "2`\r\n";
//		break;
	case ERROR_UNKNOWN_PROTOCOL_ID:
		cout << "3`\r\n";
		break;
	case ERROR_NOT_ENOUGH_MEMORY:
		cout << "4`\r\n";
		break;
	}
nRetCode=1;    
}

As you can observe I was forced to comment out three lines because I didnt find ERROR_CANNOT_COMPLETE defined in my entire hard disk Frown | :-(

Sucks as you might guess....

any help is hugely appreciated Frown | :-(
