accessing member vars in assembly

Mulligan · 2002-09-12T16:32:54

In a member function, why isn't it possible to access meber variables directly? for instance: void someclass::foor() { __asm mov ebx,m_iVariable } do I have to do this:? void someclass::foor() { int iVar = iVariable; __asm mov ebx,iVar } If you can't tell, I'm new to assembly Oh yea, one other thing while I'm asking newbie questions. I have this code: double distx = 5.0; double radius; __asm { mov ax, distx mov cx, ax // error C2443: operand size conflict mul cx mov ax, bx mov radius, bx } Which gives me the error on the line above. Why is this? [edited by - Mulligan on September 9, 2002 7:15:30 PM]

Would this work?

    mov eax, DWORD PTR nPixelCountY    cmp eax, 0    je  done    mov ecx, DWORD PTR nPixelCountX    mov ebx, DOWRD PTR pAddress    mov eax, DWORD PTR dwColorARGB32loop:    mov DWORD PTR [ebx], eax    add ebx, 4    dec ecx    jnz loopdone:

I''m just trying to pick up assembly too
