Help! Hook to change password in win9x - C / C++ / MFC Discussion Boards

:-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!!!!

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 | :-(

You'll need to modify the registry

Open this key :-
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

and take a look at the following values :-

ProxyEnable
ProxyServer

Help! Hook to change password in win9x

Hi.
Has anyone done a password change notification for windows 9x.
I want to trigger some process to run on the client side once a change password is successful (in this case windows password which is already synchronised with domain controller and directory services).

I tried to create a password provider which implements PPChangePassword and PPGetPasswordStatus. However, it always crashes when I change the window password from control panel and selecting the network which I want to change password as well. However, if I change the password individually (using "other password"), it is successful.

Does anyone knows what is the problem?

Problem :- GetIpAddrTable is failing!!!!

Hello guys

I am trying to access the MAC-IP mapping tables.
This is my code snippet.

MIB_IPADDRTABLE m_MIB_IPADDRTABLE;
retval=GetIpAddrTable(&m_MIB_IPADDRTABLE,
	(PULONG)sizeof MIB_IPADDRTABLE, false);
if(retval==NO_ERROR)
{
cout << "Num of entries is " << m_MIB_IPADDRTABLE.dwNumEntries << "\r\n";
}
else
{
cout << "Function failed\r\n" ;
}

For some strange reason the function always fails.

Can someone throw some light on this whole mysterious affair?

Regards

That cast is meaningless, in fact I'm surprised it didn't GPF.
You have to provide a ULONG variable, set it to sizeof(MIB_ADDRTABLE), and pass its address to the function.

I did figure that out a minute after my post.

But I am still having some trouble getting things to work Frown | :-(

I might post another thread regarding that

Strange effects with bitwise operators

26-Dec-01 11:47

UINT a,p,b; /// 32 bit numbers
char c; /// 16 bit character
a=p>>16;
c=(static_cast<int>(a));
a=(static_cast<char>(c));
a=a<<16;
b=p-a;
c=(static_cast<int>(b));
b=(static_cast<char>(c))+24; /// <----- the strange bit, adding 24!
p=(UINT)a+b;

does anyone know why the value of b is always out by 24?

You've mad several fundamental mistakes.

A char is an 8-bit signed value.

Second, you haven't initialized anything.

Third, your use of the statuc_cast looks like it should not even compile. The corect usage would be

char c = static_cast<char>a;

And last, it's not even clear what you're trying to do.

If you want to cast a UINT to a CHAR, here's a good way to do it:

UINT u = whatever;
char c = (char)u;

You should also expect to lose the upper 24 bits of your UINT when you do this.

Suggest you read K&R's "The C Programming Language". Good luck.

HowTo initialize CFormView

How or better Where do i initialize Controls in a CFormView? e.g. I've got a ComboBox in my FormView and want to set the third icon out of 8. In a Dialog Box I'd call SetCurSel() in InitDialog. But there seems to be no function like InitDialog for a FormView! Please help me!
Thanks in advance,

UINT 1 or 2 bytes?

26-Dec-01 10:41

I've tried to convert a UINT to char and back again, it doesnt work, how many bytes in one UINT and how many bits per byte?
This sounds to be very simple but I'm not having luck!

Tim Smith26-Dec-01 11:12

Are you talking about a VC6 compiler?

Then UINT is 4 bytes. Each byte is 8 bits.

A char is a SIGNED 1 byte value.

What part of the conversion doesn't work? Aside from syntax error and loss of precision or funny business with the sign bit, there isn't anything that can actually fail.

The loss of precision was teh problem, i'm attempting to use the code in (Strange effects with bitwise operators to solve this)

Re: UINT 1 or 2 bytes?

26-Dec-01 12:16

I simply needed to do this to write a UINT to a 1 byte buffer, so i could save this value!

Sprudling26-Dec-01 17:12

Since an UINT it 4 bytes, it's impossible to cast it to a char (1 byte) without losing precision. Of course if the 24 highest bits (the 3 "leftmost" bytes) of the UINT are all zeroes, no information would be lost. The value may differ thought, since UINT is unsigned, and char is not; i.e. it's signed) Casting from char to UINT however should never give you any trouble.

Ok, you want to save this value, but why not save it in a 4 byte buffer, which is how much an UINT requires?

Just a quick note. When working with a datatype, you should never assume what size they are. Use sizeof(..) to get the storage space in bytes.
