我在资源字典中有一个图像,我想将它作为带有 SetMenuBitMaps API 的菜单的图标,所以我在资源字典中有图像的字节数组,如何将字节转换为 IPictureDisp?我找到了这个 :
      Private Declare Function CreateStreamOnHGlobal Lib "ole32.dll" (ByRef hGlobal As Any, ByVal fDeleteOnResume As Long, ByRef ppstr As Any) As Long
Private Declare Function OleLoadPicture Lib "olepro32.dll" (ByVal lpStream As IUnknown, ByVal lSize As Long, ByVal fRunMode As Long, ByRef riid As GUID, ByRef lplpObj As Any) As Long
Private Declare Function CLSIDFromString Lib "ole32.dll" (ByVal lpsz As Long, ByRef pclsid As GUID) As Long
Private Const SIPICTURE As String = "{7BF80980-BF32-101A-8BBB-00AA00300CAB}"
Public Function PictureFromArray(ByRef b() As Byte) As IPicture
      On Error GoTo errorhandler
      Dim istrm As IUnknown
      Dim tGuid As GUID
      If Not CreateStreamOnHGlobal(b(LBound(b)), False, istrm) Then
        CLSIDFromString StrPtr(SIPICTURE), tGuid
        OleLoadPicture istrm, UBound(b) - LBound(b) + 1, False, tGuid, PictureFromArray
      End If
      Set istrm = Nothing
      Exit Function
    errorhandler:
      Debug.Print "Could not convert to IPicture!"
    End Function
但它对我不起作用,它总是返回“Nothing”。
