リソース ディクショナリにイメージがあり、SetMenuBitMaps API を使用してメニューのアイコンとして配置したいので、リソース ディクショナリにイメージのバイト配列があります。バイトを IPictureDisp に変換するにはどうすればよいですか? 私はこれを見つけました :
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
しかし、それは私にとってはうまくいきません。常に「Nothing」を返します。
