Hi

I am trying to transfer data from one application to another by sending a
pointer to a memory block. To test this out I have two applications, a
sender and a receiver. The sender fills an integer buffer and sets a pointer
to its address. Then I send a message via the interop SendMessage();.

I get the message in the Receiver ok and the pointer value received is the
same as the one sent. But when I try to get the data all I get is garbage.

To simplify things both applications are set as an unsafe class;

Send code is

fixed(int* p1=outbuff)
{
    SendMessage(recHandle, msg, (IntPtr)(p1),(IntPtr)(p1));
}

Receive code is

protected override void WndProc(ref Message m)
{
    if(m.Msg==msg)
    {
       int* pptr=(int*)m.WParam.ToPointer();
       for(int i=0;i<100;i++) richTextBox1.AppendText(i+";
"+(*pptr++).ToString()+"\n");
    }
   base.WndProc(ref m);
}
