hello does anyone know why GdipCreateBitmapFromScan0 causes memory leak, next a very simple example with a timer calling the function and removing the image.

In the task manager you can see how VB6.exe gradually increases its memory
Code:
Option Explicit
Private Declare Sub GdiplusShutdown Lib "gdiplus" (ByVal Token As Long)
Private Declare Function GdiplusStartup Lib "gdiplus" (Token As Long, inputbuf As GdiplusStartupInput, Optional ByVal outputbuf As Long = 0) As Long
Private Declare Function GdipDisposeImage Lib "gdiplus" (ByVal Image As Long) As Long
Private Declare Function GdipCreateBitmapFromScan0 Lib "GdiPlus.dll" (ByVal Width As Long, ByVal Height As Long, ByVal stride As Long, ByVal PixelFormat As Long, scan0 As Any, BITMAP As Long) As Long

Private Type GdiplusStartupInput
    GdiplusVersion              As Long
    DebugEventCallback          As Long
    SuppressBackgroundThread    As Long
    SuppressExternalCodecs      As Long
End Type
Private Const PixelFormat32bppPARGB     As Long = &HE200B
Private Const GDIP_OK As Long = 0&
Dim GdipToken As Long

Private Sub Form_Load()
    Dim GdipStartupInput As GdiplusStartupInput
    GdipStartupInput.GdiplusVersion = 1&
    Call GdiplusStartup(GdipToken, GdipStartupInput, ByVal 0&)
    Timer1.Interval = 100
End Sub

Private Sub Timer1_Timer()
    Dim hImage As Long
    If GdipCreateBitmapFromScan0(16&, 16&, 0&, PixelFormat32bppPARGB, ByVal 0&, hImage) = GDIP_OK Then
        Debug.Print hImage
        GdipDisposeImage hImage
    End If
End Sub

Private Sub Form_Unload(Cancel As Integer)
    Call GdiplusShutdown(GdipToken)
End Sub
