HICON CAntivirusPopWnd::fileIcon(std::string extention)
{
HICON icon = NULL;
if (extention.length() > 0)
{
LPCSTR name = extention.c_str();

	SHFILEINFOA info;
	if (SHGetFileInfoA(name,
		FILE_ATTRIBUTE_NORMAL,
		&info,
		sizeof(info),
		SHGFI_SYSICONINDEX | SHGFI_ICON | SHGFI_USEFILEATTRIBUTES))
	{
		icon = info.hIcon;
	}
}

return icon;

}
// 获取文件夹图标
HICON CAntivirusPopWnd::folderIcon()
{
std::string str = “folder”;
LPCSTR name = str.c_str();

HICON icon = NULL;

SHFILEINFOA info;
if (SHGetFileInfoA(name,
	FILE_ATTRIBUTE_DIRECTORY,
	&info,
	sizeof(info),
	SHGFI_SYSICONINDEX | SHGFI_ICON | SHGFI_USEFILEATTRIBUTES))
{
	icon = info.hIcon;
}

return icon;

}
