   int nImage  
);

Parameters

  • nImage
    Zero-based index of the image.

This method relies on the behavior of the ImageList_ExtractIcon macro to create the icon. Refer to the ImageList_ExtractIcon macro for more information on icon creation and cleanup.

Example

int   i, dx, cx, cy, nCount = m_myImageList.GetImageCount();
HICON hIcon;

::ImageList_GetIconSize(m_myImageList, &cx, &cy);

// Draw the images of the image list on the DC. 
for (dx = 0, i = 0; i < nCount; i++)
{
   hIcon = m_myImageList.ExtractIcon(i);

   dc.DrawIcon(dx, 0, hIcon);
   dx += cx;
}
