RE: [REQ/HELP] Display Picture as Window Icon
That doesn't work since GdipCreateHICONFromBitmap requires Bitmap to be a GDI+ Bitmap and not a HBITMAP.

However, I managed to get this working by using the code in matty's reply to [REQ/HELP] Display Picture as Window Icon. The only real thing that needed changing was that the hIcon had to be read from the DataBloc before being passed to WM_SETICON or DestroyIcon since those normal Win32 functions use the handle as a regular DWORD. Oh, and of course you made some typos. :P
js code:
var objChatWnds = {};

// Let's not forget the already opened chats
function OnEvent_Initialize(MessengerStart) {
    if(Messenger.MyStatus > 0) {
        for( var oChatWnd = new Enumerator ( Messenger.CurrentChats ); !oChatWnd.atEnd ( ); oChatWnd.moveNext ( ) ) {
            OnEvent_ChatWndCreated( oChatWnd.item() );
        }
    }
}

// Destroy our generated icons on shutdown
function OnEvent_Uninitialize() {
    for( var hChatWnd in objChatWnds ) {
        Interop.Call ( 'user32' , 'DestroyIcon' , objChatWnds [ oChatWnd.Handle ] );
        delete objChatWnds [ oChatWnd.Handle ];
    }
}

// Main function
function setDpAsIcon ( sDpLocation , oChatWnd ) {
    var GdipToken = Interop.Allocate ( 4 );
    var GdipStartupInput = Interop.Allocate ( 16 );
        GdipStartupInput.WriteDWORD( 0 , 1 );

    // Initialize GDI+
    var bInitialized = Interop.Call( 'gdiplus' , 'GdiplusStartup' , GdipToken , GdipStartupInput , 0 ) === 0;

    if ( bInitialized === true ) {
        // Load a GDI+ Image from the file
        var nImgPtr = Interop.Allocate ( 4 );
        Interop.Call( 'gdiplus' , 'GdipLoadImageFromFile' , sDpLocation , nImgPtr );
        var hImage = nImgPtr.ReadDWORD ( 0 ) !== 0 ? nImgPtr.ReadDWORD ( 0 ) : false;

        if ( hImage !== false ) {
            // Get a HICON from the GDI+ Bitmap
            var hIcon = Interop.Allocate ( 4 );
            Interop.Call ( 'gdiplus' , 'GdipCreateHICONFromBitmap' , hImage , hIcon );
            // Read the actual handle and save it
>>>            hIcon = hIcon.ReadDWORD ( 0 );<<<
            objChatWnds [ oChatWnd.Handle ] = hIcon;
            // Set the chat window icon
            Interop.Call( 'user32' , 'SendMessageW' , oChatWnd.Handle , 0x80 /* WM_SETICON */ , 0 /* ICON_SMALL */ , hIcon );
            Interop.Call( 'user32' , 'SendMessageW' , oChatWnd.Handle , 0x80 /* WM_SETICON */ , 1 /* ICON_BIG */ , hIcon );
        }
    }

    // Shutdown GDI+
    Interop.Call( 'gdiplus' , 'GdiplusShutdown' , GdipToken.ReadDWORD ( 0 ) );
}

// Set the icon on new chat windows
function OnEvent_ChatWndCreated ( oChatWnd ) {
    if ( oChatWnd.Contacts.Count === 1 ) {
        var oContact = new Enumerator ( oChatWnd.Contacts ).item();
        setDpAsIcon ( oContact.DisplayPicture , oChatWnd );
    }
}

// Remove the icon when a chat window is closed
function OnEvent_ChatWndDestroyed ( oChatWnd ) {
    if ( typeof objChatWnds [ oChatWnd.Handle ] === 'object' ) {
        Interop.Call( 'user32' , 'SendMessageW' , oChatWnd.Handle , 0x80 /* WM_SETICON */ , 0 /* ICON_SMALL */ , 0 );
        Interop.Call( 'user32' , 'SendMessageW' , oChatWnd.Handle , 0x80 /* WM_SETICON */ , 1 /* ICON_SMALL */ , 0 );
        Interop.Call ( 'user32' , 'DestroyIcon' , objChatWnds [ oChatWnd.Handle ] );
        delete objChatWnds [ oChatWnd.Handle ];
    }
}}
Just one small note: when tabbed chats are enabled, the big icon won't show up, but the small ones will still work in the title bar.

Enjoy! ;)

Luckily, it doesn't.

So my guess would be that the Image class resulted from the loaded file will already be a Bitmap instance, it simply decides which derived class to use based on the type of the loaded file.

Yes, like oChatWd where you want oChatWnd and typeof o === 'object ' where you want typeof o === 'object'. (note the loss of the space between object and ' )
But I'll forgive you because you couldn't test it. :)
