hILSmall = ImageList_Create(CX_ICON_SMALL, CY_ICON_SMALL, FALSE, NUM_ICONS, 0);
hILLarge = ImageList_Create(CX_ICON_LARGE, CY_ICON_LARGE, FALSE, NUM_ICONS, 0);


::SHGetFileInfo(_T("E:\\v.doc"),0, &shfi, sizeof(shfi),SHGFI_SYSICONINDEX|SHGFI_SMALLICON);

HICON hIcon = LoadIcon(hInstance,shfi.iIcon);

ImageList_AddIcon(hILSmall, hIcon);
ImageList_AddIcon(hILLarge, hIcon);

int t = ImageList_GetImageCount(hILSmall);
int b = t;

但是，当我在b = t行中调试时，结果是t =0.:((谁能帮我?

But when i debug in line b = t, result is t = 0. :(( who can help me?

推荐答案

SHGetFileInfo将句柄返回到图标，所以在那里无需显式加载LoadIcon.

SHGetFileInfo return the handle to the icon so there is no need to LoadIcon explicitly.

HICON hIcon = ::SHGetFileInfo(_T("E:\\v.doc"),0, &shfi, sizeof(shfi),SHGFI_SYSICONINDEX|SHGFI_SMALLICON);
ImageList_AddIcon(hILSmall, hIcon);
int t = ImageList_GetImageCount(hILSmall);
