SHGetFileInfo does not work for large icons

[nilam2477]

I need to use SHGetFileInfo to display large icons.For small icon display it works fine. If i change the parameter to display large icon (SHGFI_LARGEICON) it does not display the file with large icon, it always displays small icon. Could you pls help me hImgSmall = Win32.SHGetFileInfo(fName, 0, ref shinfo, (uint)Marshal.SizeOf(shinfo), Win32.SHGFI_ICON | Win32.SHGFI_SMALLICON); hImgLarge = Win32.SHGetFileInfo(fName, 0, ref shinfo, (uint)Marshal.SizeOf(shinfo), Win32.SHGFI_ICON | Win32.SHGFI_LARGEICON]);

Have you defined the constants correctly? public const uint SHGFI_ICON = 0x100; public const uint SHGFI_LARGEICON = 0x0; // 'Large icon public const uint SHGFI_SMALLICON = 0x1; // 'Small icon

After a bit of 'googling' is appears that SHGetFileInfo ... _LARGEICON returns the 32x32 icon, not any greater than that. You need to call SHGetFileInfo to get the image list index, then SHGetImageList to get the larger icons. Some code here[^] that may be useful.
