The suggested wrapper is .NET based which is what I'm trying to avoid so any info you can dig up will be very much appreciated.

I'm testing against 2007 but I assume whatever I come up with will be compatible with 2010.

How can I read /write an EEPROM on a PCB from my computer. Any help and or example plaese?

is this an existing PCB? what else does it hold? is there a micro-controller? what kinds of interfaces have been provided? and what kind of EEPROM (manufacturer, model, capacity, databus width, timing specs, ...)?

or is this something you still have to design?
and what is it for?

It is an existing PCB, contains a PIC16C771 connected to an EEPROM (X24C04) via I2C and all connected to a IDC connector via I2C. this IDC is connected to computer via DIO48 PCI I/O card. I2C connects both, PIC & EPROM directly to computer. I need to read and write data from EEPROM which is already having existing data in it. Here I need some method to connect and R/W to EEPROM using I2C from my computer.

so you need:
1. software that implements I2C protocol on your interface (DIO48)
2. software that implements the specific EEPROM programming on top of (1)

I've done similar things on embedded systems, long ago, and not on PC although it is perfectly doable. I'm not aware of any existing solution, although they probably exist. Try Google. For EEPROM make sure to obey the timing specifications.

Hello,

is there a specified ~~Data~~ Date variable type that i can use it with C++? I don't like to use a structure including three integers for this aim.

Thank you

Do you mean a date?
If you're using ATL/MFC then class CTime is avalable [^].

great one but when i write this code it said that the CTime is not a class or a namespace. How to help

#include<time.h>
#include<iostream>
using namespace std;

void main()
{
	//char date[9];
//	_strdate(date);
//	cout << date << endl;
	
	CTime t1(1999, 3, 19, 22, 15, 0); // 10:15 PM March 19, 1999
	CTime t2(1999, 3, 20, 22, 15, 0); // 10:15 PM March 20, 1999
	CTimeSpan ts = t2 - t1;             // Subtract 2 CTimes
  
}

That's why Carlo said "if you are using MFC/ATL", which is not your case so forget about it.

You need to include atltime.h header in order to use the CTime class. (In case you are using MFC/ATL).
I see that you have already included time.h so you can use the struct tm[^] from this header. See here[^] for standard date/time functions, macros and types. Smile | :)

Yup Thank you. I even found another Class zhicgh is CTimeSpan (based on CTime and do operations on time which the most suitable class for now.

Thnak you again and @ Cedric: the errors from VS saying that CTilme t1 is undeclarated was due to a line which end with no ; and now it works i forget to say that i was under MFC so excuse me again we are humains and we do mistakes. Hmmm | :|
