Title: Starting with DirectX - A couple of problems

Hi there,

Always experimenting I am ::)

I have taken on a few challenges here to reach this problem. But, I am sure you guru's will be able to assist.

I have started playing around with creating my own inc files and what better way to experiment than using DirectX? :lol

I have made the following include file which appears to be ok;

Code Select

D3D_SDK_VERSION equ <32>

D3DDISPLAYMODE		typedef DWORD
IDirect3D9		typedef DWORD

GetAdapterDisplayMode	PROTO :DWORD,:DWORD
Direct3DCreate9 	PROTO :DWORD
ExitProcess 		PROTO :DWORD

And my main project

Code Select

.386 
.model flat,stdcall 
option casemap:none 

includelib \masm32\lib\kernel32.lib
include directx.inc
includelib D3d9.lib

.data 

.data?
md3dObject		IDirect3D9	?
mode			D3DDISPLAYMODE	?

.code 
start:

	invoke Direct3DCreate9,D3D_SDK_VERSION
	mov md3dObject,eax

	;md3dObject->GetAdapterDisplayMode(D3DADAPTER_DEFAULT,&mode);		// C++ code
	coinvoke md3dObject,IDirect3D9,GetAdapterDisplayMode,D3DADAPTER_DEFAULT,ADDR mode

	invoke ExitProcess,eax

end start

Everything compiles ok until I get to the 'coinvoke' line. Where I get a syntax error md3dObject. I can't figure out why I am getting this syntax error. Can anyone help guide me to where I have gone wrong?

Thanks in advance :)

A sample to start is better

I have translated the six tutorials of directx 9.C.The last is meshes.
This samples seems to be improve now.
The translator is better now than when i write them,you can translate others with it and verify them.
