I am working on VC++ compiler. I want to accomplish the following

The variables s.AddrFrame.Offset and s.AddrStack.Offset contain the value of EBP and ESP respectively. I want to extract the value of old EBP and the return address. Assuming the address EBP + 1 contains the old 32 bit EBP value and EBP + 5 the return address I wrote the following code:

unsigned int old_ebp = 0;
unsigned int ret_addr = 0;

__asm{

mov old_ebp, DWORD PTR [s.AddrFrame.Offset + 1] 
mov ret_addr, DWORD PTR [s.AddrStack.Offset + 5]

}

But this is not compiling

xxxx.cpp(1130) : error C2415: improper operand type

Please Help
