Loading XP Icons from resource

Hi,

Is there anyway to load XP icons( not bitmaps ) from resource ?

Xtreme has a very nice function HBITMAP CXTPImageManagerIcon::LoadAlphaIcon(LPCTSTR pszFileName, int nWidth), but it only loads icons from a file.

I build my own LoadAlphaIcon( HINSTANCE h, LPCSTR sid, int w ), but I want to know if it is there anyway simpler to do it, because I had to add the icons to a diferent resource group than ICON.

myresource.rc

<..>

DELETE                IMAGE     DISCARDABLE     "res\delete.ico"

<..>

An this raises another question, why do Visual studio seems to damage( remove alpha layer ) on XP icons when they are added to the ICON group on the resource ?

Thankx

Hi Oleg,

thankx,

But I did no found any sample that actualy loads a XP Icon( with alpha layer ) from the resource( RT_GROUP_ICON ), is there any sample ?

<...>

SetIcon( IDI_ICON, 0x100 ); // where IDI_ICON is a XP Icon

<...>

I did however found a lot of bitmap and toolbars examples but that's not what I need.

Actualy one of the reasons that I insist on icons and not bitmaps, is that the Icon is much easer to deal with and much smaller than bitmaps on the resource, ( it probably have some kind of compression ) ?

And also one the reasons I do not use SetIcon is because I think Visualstudio 6 does not like icons with alpha layer( not just 16milion  ), everytime I add one, the alpha layer is damaged.

That is why I need to see a sample to see how it's done.

Hi Oleg,

A small bug...

HBITMAP CXTPImageManagerIcon::LoadAlphaIcon(LPCTSTR pszFileName, int nWidth)
{

 HANDLE hFile = CreateFile(pszFileName, GENERIC_READ, 0, NULL,
  OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

 if (!hFile)
  return NULL;

should be...

 if (hFile==INVALID_HANDLE_VALUE)
  return NULL;
