First-chance exception in DWB.exe (OLEAUT32.DLL): 0xC0000005: Access Violation.

Could any one tell me the meaning of the above sentence ?

try
{
	throw 100;
}
catch (...)
{
	cout << "exception";
}

try // SEH is enabled
{
	int *ptr = (int *)0x01;
	*ptr = 1000;
}
catch (...)
{
	cout << "exception";
}

I know memcpy will work but it will also wipe the data that is already in the buffer.

/* memcpy example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char str1[]="Sample string";
  char str2[]="Another string";
  memcpy (str2,str1,strlen(str1)+1);
  printf ("Contents of buffer2:",str2);
  return 0;

The only programmers that are better that C programmers are those who code in 1's and 0's

I suggest you use a std::string instead of plain char arrays,
