There's many problems here. Firstly you haven't escaped the post properly so it's hard to read. For example:
K ARUN KUMAR wrote:
reinterpret_cast(CoTaskMemAlloc(sSize * sizeof(BYTE)));

You didn't escape the < and > so some important code is missing.

You didn't bother to point out explicitly which code is in the client and which is in the server.

Surrounding code in <pre> and </pre> tags is generally considered polite, not to mention the fact that it makes the code more readable (uses a fixed width font).
You also didn't bother to ensure the code was properly indented.

In short, if you want help, put some effort in asking for it (at least as much as I do in replying!).

Now onto the code....

BYTE byt[6];
int i=0;
for(;*bytArray!=0;i++)

byt[i]=*bytArray;

::MessageBox(NULL,(LPCTSTR)"he","Msg",MB_OK);
bytArray++;
}
byt[i]=0;


This doesn't make use of size. Ever heard of buffer overruns?
What's with the (LPCTSTR)"he"? Get rid of the cast. If the string is of the wrong type casting just turns what would have been a compiler error into a runtime error and solves nothing.

//Allocate the shared Memory
pBytes = reinterpret_cast(CoTaskMemAlloc(sSize * sizeof(BYTE)));
if(pBytes == NULL)
return;


CoTaskMemAlloc does ***NOT*** allocate shared memory! You don't need to use it in this case (although there is no harm in using it).

Can you tell me more about what actually happens when you run it. Does the CDataProvider::SetData function get called? Does it display a MessageBox? How many times?
