为什么 D2D1CreateFactory 在程序集中发送错误消息

Question

到目前为止，我有一个程序，它所做的只是尝试创建一个，D2D1Factory但我收到错误消息E_NOINTERFACE，我认为我是正确的，IID_ID2D1Factory并且我已经在多个地方多次检查过。有人可以告诉我为什么它失败和/或如何修复它。

我的代码

include externals.asm
include wincons.asm
include vtable.asm
.data
include variables.asm
;include pic.asm
include riid.asm
.code
start proc frame
    DB 48h
    push rbx
    .pushreg rbx
    push r13
    .pushreg r13
    push rbp
    .pushreg rbp
    sub rsp, 80
    .allocstack 80
    lea rbp, [rsp + 80]
    .setframe rbp, 80
    .endprolog
    mov rcx, D2D1_FACTORY_TYPE_SINGLE_THREADED
    lea rdx, IID_ID2D1Factory
    mov r8, D2D1_DEBUG_LEVEL_NONE
    lea r9, ID2D1Factory
    call __imp_D2D1CreateFactory
drawscreen:

    jnc drawscreen
    xor rcx, rcx
    call __imp_ExitProcess
    mov rsp, rbp
    pop rbp
    pop r13
    pop rbx
    ret
start endp
end

外部.asm

变量.asm

Answer 1

您没有正确定义 IID_ID2D1Factory 的 UUID。问题是 UUID 的 Microsoft 二进制编码要求 UUID {06152247-6f50-465a-9245-118bfd3b6007} 的最后两个组件采用大端格式，这与采用小端顺序的前三个组件不同。所以应该是：

IID_ID2D1Factory    Dword   006152247h
                    word    06f50h
                    word    0465ah
                    byte    092h
                    byte    045h
                    byte    011h
                    byte    08bh
                    byte    0fdh
                    byte    03bh
                    byte    060h
                    byte    007h

与其自己定义此 UUID，不如使用uuid.libWindows SDK中包含的定义更容易且不易出错。
