我的程序GDI对象数猛增，大侠们给找找我哪里没释放啊

我在做我的需求的时候要在MFC里两个CStatic框里显示两幅图片，函数如下// 显示图片hWnd 为窗口句柄
int CAlertClientDlg::ShowPic(HWND hWndSnapshot1,HWND hWndSnapshot2,char * ReceivedData)
{ 
    if (NULL==ReceivedData)
    {
        return 0;
    }
HDC hDCsnapshot1=::GetDC(hWndSnapshot1);
HDC hDCsnapshot2=::GetDC(hWndSnapshot2);
CWnd * pWndSnapshot1= parentPointer->FromHandle(hWndSnapshot1);
CDC * pDCSnapshot1 =pWndSnapshot1->GetDC();
CWnd * pWndSnapshot2= parentPointer->FromHandle(hWndSnapshot2);
CDC * pDCSnapshot2 =pWndSnapshot2->GetDC();
    
    IPicture *pIPictureSnapShot1;
    IStream *pStmSnapShot1;
    BOOL bResultSnapShot1;
IPicture *pIPictureSnapShot2;
IStream *pStmSnapShot2;

memcpy(&structureSize,ReceivedData+4,4);
memcpy(&snapShot1Size,ReceivedData+8,4);
memcpy(&snapShot2Size,ReceivedData+12,4);
memcpy(&alertXMLlength,ReceivedData+16,4);
AlertDetail * detail = (AlertDetail *)(ReceivedData+32);
    
    //图片1分配全局存储空间
    HGLOBAL hGlobalSnapShot1 = GlobalAlloc(GMEM_MOVEABLE, snapShot1Size);

我注释掉这个函数时没事，用上后一会程序没反应了，看GDI对象数上千的也在不停增长，因为我也在不停的刷屏，自己也释放了些对象可是还是没有解决？那位大哥给看下？
