SYS in assembly

[Ric]

Could someone please explain why this doesnt work, when converting this

Code: Select all

SYS DevCon.UpdateSubresource%, DevCon%, CBMenu2D%,       0, 0, CBMenu2D{},             0, 0

into this

Code: Select all

        push                   0
        push                   0
        push             DWORD [^CBMenu2D{}]
        push                   0
        push                   0
        push             DWORD [^CBMenu2D%]
        push             DWORD [^DevCon%]
        CALL             DWORD [^DevCon.UpdateSubresource%]

Thanks in advance

Could someone please explain why this doesn't work

Since CBMenu2D{} is a vector, not scalar, object shouldn't you be passing it as:

Code: Select all

        push    DWORD CBMenu2D{}

or if you prefer:

Code: Select all

        push    DWORD PTR(CBMenu2D{})

The indirection you are using in your original code definitely doesn't look right to me.

Incidentally the x86-32 CPU can only push 32-bit values, making the DWORD qualifiers superfluous I would expect.

Thanks Richard, I'll try in the morning

Thanks Richard, it worked a charm.

The code you have now changed:

Code: Select all

        push             DWORD [^CBMenu2D{}]
