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(<someDLLname>);
 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<btnCount;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!

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);

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...

Hi,

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

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.
