How to use ado to visit the database in C++.
It's better to show me some samples or links.
Thanks!

Howdy codies,
I'm getting a little bored with the plain old text editing in VS.Net for some of the code I have to edit (particularly makefiles), and I've been scouring MSDN for information on hwo to implement a new code editor, but to no avail.
Theres hints alluding to some secret SDK that VSIP (Visual Studio Intregration Partners), but no concrete information.
I als had a quick look at a .resx editor, which relied on the VSIPExtras package, but thats not publically available apparently.
So anyone know where to start for building a new code editor in VS.Net?

I'm getting a value that represents my ip address in a long - 16951488. I can then ping that number and see my IP in network byte order - 1.2.168.192
Does anyone know of a function that will take the first long and convert it to an IP address?
Cheers,

Cheesy solution, but should work. (Warning: untested!) 
void convertLongToIpAddress
(long nLong,
unsigned char& ch0, <code>
unsigned char& ch1,
unsigned char& ch2,
unsigned char& ch3) <code>
{
ch0 = (unsigned char) (nLong & 0xFF000000) / (256 * 256 * 256);
ch1 = (unsigned char) (nLong & 0x00FF0000) / (256 * 256);
ch2 = (unsigned char) (nLong & 0x0000FF00) / 256);
ch3 = (unsigned char) nLong % 256;

Thanks Ravi, but this resulted in nothing in each of the char values.

It's an order of operations problem - put brackets around everything after the cast to unsigned char, the number is getting cast first, then divided.
I'd also replace the 256 divides with shifts.
void convertLongToIpAddress (long nLong,
unsigned char& ch0,
unsigned char& ch1,
unsigned char& ch2,
unsigned char& ch3) // lowest part
{
ch0 = (unsigned char) ((nLong & 0xFF000000) >> 24);
ch1 = (unsigned char) ((nLong & 0x00FF0000) >> 16);
ch2 = (unsigned char) ((nLong & 0x0000FF00) >> 8);
ch3 = (unsigned char) (nLong % 256);
}

Why the '&' operation? The shifts cause the bits you need to be in the LS byte not? So the cast should truncate the other bits...
So the following code does the same in less CPU cycles:
void convertLongToIpAddress2 (long nLong,
unsigned char& ch0,
unsigned char& ch1,
unsigned char& ch2,
unsigned char& ch3)
{
ch0 = (unsigned char) (nLong >> 24);
ch1 = (unsigned char) (nLong >> 16);
ch2 = (unsigned char) (nLong >> 8);
ch3 = (unsigned char) (nLong);
}

Yeah, this occured to me in the shower a half hour ago. Does that make me a total nerd ?

Nah. I think that most developers are not nerds, even if they think about IT related stuff when they are taking a shower! Other people think about their work all the time. They even talk about it during dinner. I bet that most developers don't do that, since we know that nobody is going to understand what we will say about 95% of the time... So the real nerds (in terms of being obsessed with their work and talk about nothing else) is everybody else!

Well, I thought of a faster way again on the way to work this morning...
void ConvertLongToIPAddress( long nLong,
unsigned char& ch0,
unsigned char& ch1,
unsigned char& ch2,
unsigned char& ch3) // lowest part
{
unsigned char * pIP = (unsigned char *) & nLong;
ch0 = pIP[3];
ch1 = pIP[2];
ch2 = pIP[1];
ch3 = pIP[0];
}
I seem to recall a Dilbert cartoon where he has to hand in a timesheet and says 'the time I spent doing nothing in meetings is marked as work, and the time I spent designing circuits in the shower is not on there'.

LOL! Where do you get some rest?
I give up here. I might be able to prduce a slightly better result in assembly, but I want get back to something I left behind...

About five hours a night. Except when I have sticky programming problems, then I dream about them. Not that I'm obsessive or anything.

Yeah, they rule. NEver had a bad boss, so I can't relate, but I still love it. The books are even better, especially 'The Dilbert Future'. If you don't have it, get it. It's REALLY funny

Not totally but close. 
It used to be a running joke between me and my boss. I would always come up with my best ideas in the shower so one day after several instances of this he said, "you know, we should pay your water bill."

*grin* Now that would be nice. I often wake up with the answer to my programming questions, I wonder what bill i could give my boss in that instance ?

There's also:
in_addr ia;
ia.S_un.S_addr = 16951488;
TRACE(_T("%u.%u.%u.%u\n"),
ia.S_un.S_un_b.s_b4,
ia.S_un.S_un_b.s_b3,
ia.S_un.S_un_b.s_b2,
ia.S_un.S_un_b.s_b1);

That's just what I was thinking. I had forgotten it was already built though.

Install the Platform SDK.
I don't think those two files came with the Visual Studio 6.0 distribution.
Make your Visual Studio development environment search into the platform SDK include and library folder ahead of the one delivered with Visul Studio 6.0.
