Hi,

 Many thanks’ for you patient, it works correctly now.

I have just I suggest to you : how you could know I can load icon with alpha support on .res directly but I can load it how custom resource. This sub loads a custom resource and returns a byte array.

Public Function LoadDllData(ByVal Index As Long, Optional ByVal ResFormat As String = "CUSTOM") As Byte()

'*************************************************************************

'* Loads raw data from a dll

'* Parameter:

'*           Index (required) :   Integer specifying the Identifier (Id) of

'*                                the data in the resource file.

'*           resformat (optional):   Constant that specifies the type of

'*                                the data:

'*                                AVI, WAVE, RTF ,RCDATA ......

'*                                default value: CUSTOM

'* Return value :    Byte-Array

'*************************************************************************

    Dim hResInfo As Long

    Dim hResData As Long

    Dim pBuffer As Long

    Dim nCount As Long

    Dim bBuffer() As Byte

    On Error Resume Next

    Debug.Assert (m_hInstance <> 0)

    ' If you get this debug assertion, you forgot to load a dll

    ' Set the DllName property to a valId file before calling

    ' this method

    hResInfo = FindResource(m_hInstance, Index, ResFormat)

    ' If you get this debug assertion, the resource you

    ' specified, was not found in the resource dll you are using

    ' Check the Id and the resource type

    Debug.Assert (hResInfo <> 0)

    If hResInfo > 0 Then

        nCount = SizeofResource(m_hInstance, hResInfo)

        ' We do not want to load empty data

        If nCount = 0 Then

            Exit Function

        End If

        ' Load the resource into memory

        hResData = LoadResource(m_hInstance, hResInfo)

        If hResData > 0 Then

            ' and lock it

            pBuffer = LockResource(hResData)

            ' Fill byte array with memory block

            ReDim bBuffer(nCount - 1)

            CopyMemory bBuffer(0), ByVal pBuffer, nCount

        Else

            Err.Raise 31037, , "Error loading from file"

            Exit Function

        End If

    Else

        Err.Raise 326, , "Custom resource with Identifier " & Format$(Index) & " not found."

    End If

    LoadDllData = bBuffer

End Function

Public Property Let DllName(ByVal vData As String)

'*************************************************************************

'* Setting this property loads the specified dll. A previous loaded dll

'* will be unloaded.

'*************************************************************************

    On Error Resume Next

    If m_hInstance <> 0 Then FreeLibrary (m_hInstance)

    m_hInstance = LoadLibrary(vData)

    ' If you get this debug assertion, your program cannot load

    ' the dll. Check the Path and the filename. The dll itself

    ' may be corrupt.

    Debug.Assert (m_hInstance <> 0)

    ' Generate an runtime-error Identical to VB LoadResString

    If m_hInstance = 0 Then

        Err.Raise 48, , "Error in loading DLL: " & vData

        m_sDllName = vbNullString

    Else

        m_sDllName = vData

    End If

End Property

….

I think may be a good improvement create a new function like this:

ImageManager.Icons.LoadIconData(IconData() As Byte, Command as Long, imageState as XTPImageState)

Or load a custom resource directly from a module like the function ImageManager.Icons.LoadBitmapFromResource, so every user can import alpha icons in a resource file as custom resources and use them.

Best regards,

This is my test application. ddIcon and ddIcons are GDI+ support class for draw icons with alpha support. I don't understand why it work with xtpImageHot (and other) but not with xtpImageNormal.

Thanks' you
