Hi, if you remember i asked here this question not long ago.

I need to write 2 applications which runs at the same time on the
computer (Windows-2000) and share same piece of memory for 
exchanging data between each other (this piece of memory will
contain a matrix of 400 x 500 float numbers (or 'int' , i still 
don't know) so if for example one application change this matrix,
the anther application can take the matrix from the memory and 
use it, or display it for example...

Can i allocate an array like this - 

float array[500][400];

then write it's address ( &array[0][0] ) and size (500x400) in
a file, so the other application can read the file and access
the array by using the pointer and the size from this file?

--  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  

This is what i tried to do and it's not working OK - 

First i run the 'Master' application and press it's button - 

int MyBuff[50], *BuffPtr = NULL; // Globals 

void __fastcall TForm1::SpeedButton1Click( TObject *Sender )
{
  MyBuff[0] = 1;
  MyBuff[1] = 2;
  MyBuff[2] = 3;
  MyBuff[3] = 7;
  MyBuff[4] = 11;
  MyBuff[5] = 13;
  MyBuff[6] = 17;
  MyBuff[7] = 21;
  BuffPtr = &MyBuff[0];
  MyBuff[8] = 99;
}

and i can see that BuffPtr points to the address 0x40371C.

then (without stopping the 'Master' running) i'm running the
'Slave' application and press it's button which have the code -

int MyBuff[50], *BuffPtr = NULL; // Globals 

void __fastcall TForm1::SpeedButton1Click( TObject *Sender )
{
  BuffPtr = (int *)0x40371C; // Same address as i saw in master!
  MyBuff[0] = BuffPtr[0];
  MyBuff[1] = BuffPtr[1];
  MyBuff[2] = BuffPtr[2];
  MyBuff[3] = BuffPtr[3];
  MyBuff[4] = BuffPtr[4];
  MyBuff[5] = BuffPtr[5];
  MyBuff[6] = BuffPtr[6];
  MyBuff[7] = BuffPtr[7]; 
}

But Although that i see that 'BuffPtr' points to the same 
address in the 2 applications (0x40371C) in the 'Slave' watch i 
see that MyBuff[] buffer have 0 in all it's cells, and not 
as i expected to see, the numbers 1, 2, 3, 7.... which i set in 
the 'Master'.

Why does it not working? please.

Thanks,
Ramy
