How would one get the icon of a particular file type like in ''My Computer''. I have a list box with a list of files of various extensions, and I need to get the file-type icon and specify the icon when the ListBox item is inserted. For example if I had a BMP file to add to the listbox, the icon would be the icon with the shapes and brush.

Look in HKEY_CLASSES_ROOT in the registry. The ".bmp" key will have a value (Default) which is the name of another key in HKEY_CLASSES_ROOT. Look in there and you'll find another key named "Default Icon". The (Default) value in there is the name of the icon (the path + the icon's number in that file).

You can use ExtractIcon to get the handle of the icon (HICON) from that file.

Programmatically, you''ll need to use SHGetFileInfo( most of these ''shell'' type functions begin with SH.. helpful for MSDN searching )...

Here is a code snippet:

SHFILEINFO stInfo;
ZeroMemory( &stInfo, sizeof( SHFILEINFO ) );

//--Lets get the HICON, as well as the location info..
// Note that you are responsible for cleaning up the HICON
// with DestroyIcon( HICON ), after you have used it..
// ie, you''re done drawing...
if( SHGetFileInfo( "c:\\bug.txt", 0, &stInfo,
sizeof(SHFILEINFO),
SHGFI_ICON | SHGFI_ICONLOCATION ) )
{
//--Let''s display the icon...
m_staticImage.SetIcon( stInfo.hIcon );
}//endif

m_staticImage is a CStatic object. If you wanted to display in a list ctrl, you''d need to create an image list..

Hope that is helpful..
