Cool, that works fine as long as I only load the 16x16 size, but that's the size I need anyway. Now my app is very nice looking.

Hi,

use wndReportControl.GetImageManager() to get ImageManager of report.

That worked great for everything except for the report column icons. Those come from an image list and I don't see a method in CXTPReportColumn that uses an icon.

Any ideas on that?

Thanks! I was thinking I was going to have to have somebody redraw all my icons...

yes, don't use CImageList to load icons.

set icons directly

CXTPImageManagerIconHandle hIcon;

hIcon.CreateIconFromResource(iconInst, iconIds[x].cmd, szResourceIcon, FALSE)

XTPImageManager()->SetIcon(hIcon, cmd);

I don't know if it's a black problem or not, but my alpha channel on my custom icons looks like a big black hole around the icons. I've noticed in other places in this forum that i should stop using CImageList, but I'm not sure how to do that. Here's my icon loading code (I load icons from a resource-only DLL so I can share between apps):

 HINSTANCE iconInst = (HINSTANCE)LoadLibrary();
 if(iconInst)
 {
  CImageList imgList32;
  CImageList imgList16;
  HRESULT hr;
  imgList32.Create(32,32,ILC_COLORDDB|ILC_MASK,0,1);
  imgList16.Create(16,16,ILC_COLORDDB|ILC_MASK,0,1);
  stdButtons = new UINT[btnCount];
  int howMany32=0;
  int howMany16=0;
  for(int x=0;x  {
   stdButtons[x] = iconIds[x].cmd;
   HICON hIcon = ::LoadIcon(iconInst,MAKEINTRESOURCE(iconIds[x].icon));
   if(!hIcon)
   {
    hIcon = AfxGetApp()->LoadStandardIcon(IDI_QUESTION);
   }
   howMany32 = imgList32.Add(hIcon);  // load the 32x32 one
   howMany16 = imgList16.Add(hIcon);  // and the 16x16
  }
  // now set both sizes of the images for XTP...
  hr= XTPImageManager()->SetIcons((CImageList&)imgList32,stdButtons,btnCount,CSize(32,32));
  hr= XTPImageManager()->SetIcons((CImageList&)imgList16,stdButtons,btnCount,CSize(16,16));

Any ideas?

Thanks!
