[求助]：对话框中如何显示dwg文件或幻灯片

沉沉

我现在需要在对话框中显示多个dwg图片，以给用户一个直观的印象，然后用户在选择相应的零件。
以前用DCL编写对话框，好像是直接显示幻灯片，不知道用ARX在VC编写的对话框中能不能实现这一功能。如果不能那有什么变通的方法吗？
这里先谢谢各位了！！！

Include File

dbmain.h

Adesk::Boolean

acdbDisplayPreviewFromDwg(
    const char *pszDwgfilename,

    void* pPreviewWnd);

pszDwgfilename        Input path\filename string
pPreviewWnd        Input HWND for window within which to display preview

This function obtains the preview image (if any) of the drawing specified by pszDwgfilename and displays it in the window identified by the HWND argument pPreviewWnd.
The image size varies up to a maximum size no larger than 256 x 188 pixels. If the pPreviewWnd window is larger than the image, then the image will be stretched to fit. But, if the window is smaller than the image, the image will not be adjusted and will spill out beyond the window's borders.

Returns Adesk::kTrue if successful, otherwise it returns Adesk::kFals
